Technical Field

The invention relates to the technical field of machinery, in particular to a pitching adjusting device and display equipment.

Background

The screen size and weight of the current flat panel display are gradually increased, and along with the increasingly expanded application range and scenes of the flat panel display screen, the requirement for the flexibility of the flat panel display is continuously increased, and the pitching angle adjusting function which is not taken into consideration in the past is gradually important.

Most current flat panel displays are not adjustable in pitch angle or can only support pitch adjustment over a small angular range (typically within 15 deg.). Meanwhile, the locking force requirement of the fixed flat panel display device at the pitching angle is high, and when the locking force is insufficient, the flat panel display easily slides down and turns over, so that the problems of labor waste, safety and the like in the adjusting process of the flat panel display are caused.

The pitch adjustment of the existing small and medium-sized display is generally realized by utilizing two joint supports, wherein one joint support is fixed on the support, the other joint support is fixed on the display, a common rotating shaft (similar to a door hinge) is arranged between the two joint supports, and two ends of the rotating shaft are locked, so that a certain damping force is generated when the flat panel display pitches. When the weight of the flat panel display is not large, the method is simple and reliable, and the adjustment of the pitching angle of the flat panel display can be effectively realized. However, when the weight of the display is large, it becomes laborious to perform the tilt adjustment of the flat panel display using the above-described structure. To solve the problem of adjustment effort, technicians have begun to add torsion springs between the two knuckle supports to adjust the torsion force to provide a counter-torsion force to counteract the force of the display sagging. However, when the weight of the flat panel display is further increased, the above-mentioned joint bracket with the additional torsion spring cannot solve the problem of the adjustment difficulty. In addition to the above-mentioned structure for adjusting the flat panel display, the existing manufacturers also use gas spring assistance or electric assistance to solve the problem of laborious adjustment. However, even if the problem of laborious adjustment is solved, the pitching adjustment angle of the flat panel display cannot be increased, and the effect of simply, conveniently and reliably adjusting the flat panel display cannot be realized.

As shown in fig. 1 and 2, a typical flat tv stand in the prior art is used to fixedly mount a flat tv on a wall. The support comprises a first fixing frame 1 'and a second fixing frame 2', wherein the first fixing frame 1 'is used for being fixed with a wall, and the second fixing frame 2' is used for being fixed with the flat-panel television. The first fixing frame 1 ' and the second fixing frame 2 ' are detachably connected through a connecting frame 3 ', the connecting frame 3 ' comprises a first adjusting unit 31 ' in an X shape and a second adjusting unit 32 ' fixedly connected with the first adjusting unit 31 ', the first adjusting unit 31 ' is used for adjusting the horizontal distance between the first fixing frame 1 ' and the second fixing frame 2 ', and the second adjusting unit 32 ' is used for adjusting the pitching angle of the flat-panel television relative to the horizontal plane. The second fixing frame 2 ' is provided with a rotation fixing part 21 ', the rotation fixing part 21 ' is fixedly connected with the second adjusting unit 32 ' to form a rotation center point, and the second fixing frame 2 ' rotates around a horizontal shaft passing through the rotation center point in a pitching manner. The second fixing frame 2 'is further provided with a rotating chute, the second adjusting unit 32' is provided with a sliding block 321 'extending into the rotating chute 22', the sliding block 321 'is provided with threads, the second fixing frame 2' rotates under the action of external force, the sliding block 321 'slides along the rotating chute 22', and when the second fixing frame rotates to a position required by a customer, the locking nut 4 'and the sliding block 321' are matched and locked in a threaded mode, so that the flat-panel television is fixed to the position required by the customer, and pitching adjustment is achieved.

As can be seen from fig. 1 and 2, the angle at which the flat tv can tilt is equal to the arc of the rotating chute 22 ', and due to the size limitation, the arc of the rotating chute 22' can be limited to a small range, such as +8 ° to-10 °. And, when the flat tv is vertically disposed, its center of gravity is in front of the second mount 2 'and the center point of rotation is behind the second mount 2'. When the mass of the flat-panel television is larger, the common locking nut 4' cannot realize the locking effect.

Therefore, the device for adjusting the display equipment such as the flat-panel television and the like in the prior art has the following defects:

1. the pitching adjusting angle is small, the problem of difficult locking can occur when the angle is slightly large, and potential safety hazards exist;

2. the adjustment is labor-consuming, if fine position adjustment is required, at least two persons are required to cooperate together, and one person cannot complete fine adjustment;

3. can not be stopped at any position according to the needs of users, and is inconvenient to use.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Compared with the pitching adjusting device in the prior art, the pitching adjusting device in the invention has the advantages that the adjustable pitching range is larger, the adjusting process is more time-saving and labor-saving, the adjusting process can be easily completed by one person, in addition, the pitching adjusting device in the invention is used for adjusting the pitching angle of the display unit, the effect of random stop can be realized at any position in the adjusting range without manual locking operation, the use satisfaction of users can be greatly improved, and the core competitiveness of products is effectively enhanced.

Because the pitching adjusting device in the background art has the defects that the pitching adjusting angle is small, the locking is difficult to occur easily due to a slightly larger angle, the potential safety hazard exists, the adjusting process is time-consuming and labor-consuming, the device cannot be stopped at a position required by a client at will, and the like, the applicant carries out deep research in order to solve the problems. In the research process, the applicant finds that the mirror capable of being turned up and down around the rotating shaft can be used in daily life, pitching adjustment of any angle can be carried out under the action of external force, and the mirror can be stopped at any position in a state that locking is not needed after the external force disappears. The applicant researches and discovers that the rotating shaft of the mirror penetrates through the center of the mirror, and only the inertia of the mirror and a little rotation damping need to be overcome in the up-down overturning process, so that the method is the most labor-saving method for up-down pitching adjustment. Because the upper part, the lower part, the front part and the rear part of the mirror are balanced, the mirror can easily rotate even if the mirror is large and heavy, and can stop at any position.

The applicant then conceived to apply the above-described method applied to the mirror-flipping adjustment process to the pitch adjustment process of a display unit such as a flat panel display. In continuing research and experimentation, the applicant found that the above method is feasible when the size of the display unit is small, but is not applicable when the size of the display unit is large, for example, several tens of inches large, and thus the support frame for supporting the display unit is actually too large, too heavy, and too obtrusive. More importantly, the standard fixed interface of the display unit such as a flat panel display is arranged in the middle of the back of the display unit, if rotating shafts are added on two sides of the display unit, adjusting devices matched with the display unit in structure need to be customized for different displays, which is obviously unrealistic, and meanwhile, the customization of a special adjusting device is not convenient enough, is not beneficial to popularization and use, and is not beautiful.

Although it is not desirable to add a frame to the display unit that mimics the way the mirror is turned, the results of the above studies are desirable, i.e., the pitch adjustment is easiest when the axis of rotation passes through the center of gravity of the object. Further research by the applicant has found that the centre of gravity of a display unit such as a flat panel display is generally located within the display unit, making it impossible to use a rotating shaft through the centre of gravity to provide a rotational support position. Further, all the supporting members for supporting and the adjusting members for position adjustment in the display unit are provided on the back case of the display unit or at a position outside the back case, which makes it impossible to mount a solid shaft as a rotation shaft passing through the center of gravity. However, the applicant has found that if the display unit such as a flat panel display can be rotated up and down around a virtual rotation axis passing through the center of gravity of the display unit, the pitch adjustment angle can be increased, and the display unit can be stopped freely within the range of the pitch angle.

The schematic diagram of the pitch adjustment mechanism of the present invention will be described in detail with reference to fig. 3. A virtual axis X is set, which is displayed as a point in fig. 3 for reasons of viewing direction, and the point of the center of gravity B coincides with the virtual axis X in fig. 3. When the display unit 100 is mounted on the pitch adjusting apparatus, the display unit 100 is turned up and down about the axis X as shown in fig. 3. It should be noted that the virtual axis X does not exist when the pitch adjustment device is actually manufactured, and the pitch adjustment device in the present invention is designed in an ideal manner, ignoring the influence of some factors, that is, assuming that the center of gravity of the display unit 100 is located inside the display unit 100 and at a half of the thickness of the display unit 100, that is, the center of gravity is located at a distance equivalent to the distance between the display surface of the display unit 100 and the inner side surface of the rear side wall of the display unit 100 (the inside of the display unit is the inside, and the outside of the display unit is the outside). The solid lines in fig. 3 indicate that the solid lines exist at positions where the solid structures exist when designing and manufacturing the pitch adjustment apparatus; the dashed line indicates that no solid structure is present at the location of the dashed line when the pitch adjustment device is manufactured, and is provided only for illustrating the principle.

In FIG. 3, BD is perpendicular to AC and point D is the drop foot; b ' D ' is perpendicular to A ' C ', and the point D ' is a drop foot; b ' D ' is perpendicular to A ' C ', and the point D ' is a drop foot. ABC, a 'B' C ', a "B" C "are three congruent triangles, and AB equals BC, so BD equals B' D ═ B" D ". AA ″, CC "is set so AA" is also parallel to CC ". B 'B "is fixed in position and B' B ═ a 'a ═ C' C, and the three are parallel to each other. It can be deduced from the above conditions that when a 'B' C 'and a "B" C "are rotated about B' and B", respectively, AC is also rotated about the virtual axis X, whereby a wide range of pitch angles can be achieved, such as a pitch angle in the range of 45 ° with respect to the vertical plane.

Here, the length of the BD is a set distance from the center of gravity of the display unit to the mounting backplate of the display unit, and it should be noted that, in order to explain the principle of the pitch adjustment device in the present invention, it is assumed that the length of the BD is constant, but in the actual application process, the size of the BD is changed with the thickness of the display unit, and needs to be adjusted according to actual needs. When the adjustment is carried out, the adjustment is realized by installing different sizes of parts at the position B 'D' and the position B 'D' on the pitch adjusting device. In the prior art, the display unit such as a flat panel display is thinnest and can be less than 20mm, and the thickest can exceed 200mm, and the BD is set by selecting a common intermediate value, for example, 50mm, in this case, basically, the virtual axis of the pitch adjusting device can pass through the center of gravity of the display unit (there may be some errors, but the adjustment of the pitch angle is not greatly affected), so that the pitch adjusting range is large, and the adjustment is easy.

Further, in order to prevent the rotation from being too flexible, some damping force may be added appropriately when designing the pitch adjustment device, and the damping force may well offset some error between a smaller virtual axis and the center of gravity of the display unit 100. However, if the vertical distance between the virtual axis X and the center of gravity is large, the pitch adjusting device is difficult to automatically lock, and at this time, the error between the two cannot be cancelled, the BD value needs to be adjusted again, and the parts located at the positions a ' B ' C ' and a "B" C "are replaced, so that the adjustment is difficult and the disassembly and assembly are laborious.

Further, in order to solve the above problem, the applicant has studied and found that the problem can be solved by adding an adjustment structure (not shown in the drawings) for adjusting the lateral displacement between the AC position and the display unit 100. The display unit 100 is fixed on an adjustment structure, the adjustment structure is connected to the AC, and when the center of gravity of the display unit 100 is closer to the back plate of the display unit 100, the adjustment structure moves toward the virtual axis direction; when the center of gravity of the display unit 100 is far from the back plate of the display unit 100, the adjusting structure moves away from the virtual axis. Of course, the adjustment structure is located between BDs regardless of the adjustment.

As shown in fig. 4 to 6, the present invention provides a pitch adjustment apparatus to which the above-described principle is applied. The pitching adjusting device comprises a first fixing part 1 and a second fixing part 2, wherein the first fixing part 1 is used for fixedly mounting a device to be adjusted (not shown in the figure), the device to be adjusted is a display unit such as a flat panel display, and the second fixing part 2 is used for being fixed on a fixing structure, and the fixing structure can be a wall or other structures which are arranged on the wall, can move relative to the wall, but have certain bearing performance and certain rigidity, such as a fixing mounting rack and the like. The structure of the first fixing portion 1 and the second fixing portion 2 is not specifically limited, and is usually preferred to facilitate installation, manufacture and processing, and considering that the flat panel display unit is mostly of an approximate flat panel structure, the wall is of a planar structure, and problems such as installation reliability and stability, the first fixing portion 1 and the second fixing portion 2 should have an installation plane, so as to facilitate installation and fixation. In a specific embodiment, as shown in fig. 4, the first fixing portion 1 and the second fixing portion 2 are both concave, the openings of the first fixing portion 1 and the second fixing portion 2 are opposite, and a certain distance is left between the first fixing portion 1 and the second fixing portion 2 for accommodating a pitch adjusting assembly 3 (described in detail later). Specifically, the first fixing portion 1 includes two first fixing side plates 11 and a first fixing panel 12 located between the two first fixing side plates 11, and the first fixing panel 12 is parallel to the display surface of the display unit. The second fixing portion 2 includes two second fixing side plates 21 and a fixing second fixing panel 22 located between the two second fixing side plates 21, and the second fixing panel 22 is parallel to a fixing structure (e.g., a wall). Wherein, a plurality of mounting holes can be arranged on the second fixing part 2 according to the mounting requirement to facilitate the mounting. The first fixing portion 1 and the second fixing portion 2 are both of an integral structure, and are preferably made of a metal material so as to have certain rigidity and strength and play a good supporting role. Preferably, a plurality of through holes are formed in the second fixing panel 22 and the second fixing side plate 21 of the second fixing portion 2 in a regular arrangement, so that the second fixing portion 2 can be lightened and the appearance of the second fixing portion 2 can be enhanced.

Further, the pitch adjustment device further includes a pitch adjustment assembly 3, and the pitch adjustment assembly 3 is disposed between the first fixing portion 1 and the second fixing portion 2. The pitching adjusting assembly 3 comprises two groups of pitching adjusting units 31 symmetrically arranged relative to a center line of the first length of the device to be adjusted, each group of pitching adjusting units 31 comprises two connecting structures 311 arranged side by side along the second length direction of the device to be adjusted, each connecting structure 311 extends along the third length direction of the device to be adjusted, and each connecting structure 311 is rotatably connected with the first fixing portion 1 through a connecting end portion 3111. In a specific embodiment, the display surface of the display unit is generally rectangular, the first length direction is the length direction of the display surface, the second length direction is the thickness direction of the display unit, and the third length direction is the width direction of the display surface, which can also be understood as the height direction of the display unit. In this embodiment, the connecting structure 311 is two connecting rods, two connecting rods are arranged on each first fixing side plate 11 of the first fixing portion 1, and the two connecting rods are arranged in parallel up and down along the height direction of the display unit, so that the structure is simple, the processing is convenient, and the cost of the pitching adjusting device can be effectively reduced while the function of the pitching adjusting device is realized. As shown in fig. 4, the connecting structure 311 is located outside the first fixed side plate 11 and inside the second fixed side plate 21 for easy installation, and while avoiding interference, the second fixed side plate 21 can also protect the structure located inside the second fixed side plate, so as to avoid the external environment from affecting the normal operation of the pitch adjusting assembly. The connecting structure 311 is rotatably connected to the first fixed side plate 11 and the second fixed side plate 21 through the first connecting end portion 3111A and the second connecting end portion 3111B, respectively, and it is understood that the connecting structure 311 in this embodiment is a single straight rod, but in other embodiments, the connecting structure 311 may also be other structures, such as a multi-branch rod, etc., or other types of structural members, without affecting the pitch adjusting effect of the pitch adjusting device, and is not limited to a rod.

Further, two pitching adjusting pieces 32 are arranged between the two connecting structures 311, the two pitching adjusting pieces 32 are parallel to each other along the length direction of the display surface of the device to be displayed, and the two pitching adjusting pieces 32 are arranged in a staggered manner along the second length direction. In the present embodiment, the pitch adjusting member 32 is a substantially triangular plate member formed integrally, but it should be understood that the pitch adjusting member 32 may have other structures as long as the connecting line between the pitch adjusting member and the connecting structure 311 and the second fixing portion 2 is a triangular structure. The first pitch adjustment member 322 of the two pitch adjustment members 32 in this embodiment corresponds to a 'B' C in fig. 3, and the second pitch adjustment member 323 corresponds to a "B" C in fig. 3.

A straight line extending in the first longitudinal direction through the center of gravity of the device to be adjusted is perpendicular to the plane in which the two connection structures 311 lie, and the connecting line of the drop foot and the center point of the two connection end portions 3111 encloses a reference triangle. The center point of the connecting end portion 3111 is the position where the connecting structure 311 is connected to the first fixing portion 1, and is not changed with the structure of the connecting end portion 3111. The connecting lines of the central points of the three rotating end portions 321 form an adjusting triangle, the adjusting triangle and the reference triangle are congruent triangles, and the plane where the adjusting triangle is located is parallel to the plane where the reference triangle is located. The reference triangle in this embodiment corresponds to ABC in fig. 3, and the adjustment triangle corresponds to a ' B ' C ' and a "B" C ".
