Detailed Description

To make the objects, technical solutions and advantages of the present disclosure more apparent, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

The disclosed embodiment provides a light joint adjusting mechanism for adjusting the irradiation positions of a low beam reflector 100 and a high beam reflector 200 of an automobile. Fig. 1 is a top view of a light joint debugging mechanism, specifically corresponding to a left lamp of a vehicle, as shown in fig. 1, the light joint debugging mechanism includes a base 1 and a joint debugging component 2.

The base 1 is fixedly installed in the lamp housing 300, and the base 1 includes a low beam reflector fixed hinge portion and a high beam reflector fixed hinge portion.

The joint debugging component 2 comprises a joint debugging support 21, an electric adjusting module 22 and a manual adjusting module 23, the joint debugging support 21 is slidably installed in the lamp shell 300, the joint debugging support 21 comprises a low beam reflector movable hinging part and a high beam reflector movable hinging part, the electric adjusting module 22 is slidably installed in the lamp shell 300, the sliding direction of the electric adjusting module 22 is the same as that of the joint debugging support 21, and the electric adjusting module 22 is used for driving the joint debugging support 21 to move towards or back to the low beam reflector fixed hinging part.

Fig. 2 is a schematic structural diagram of a manual adjustment module, and referring to fig. 2, the manual adjustment module 23 includes an adjustment screw 231 and an adjustment gear 232, a middle portion of the adjustment screw 231 is rotatably mounted on the lamp housing 300, an axial direction of the adjustment screw 231 is the same as a sliding direction of the electric adjustment module 22, one end of the adjustment screw 231 is in threaded fit with the electric adjustment module 22, and the other end of the adjustment screw 231 is engaged with the adjustment gear 232.

When the light joint adjusting mechanism provided by the present disclosure adjusts the dipped headlight reflector 100 and the high beam reflector 200, the dipped headlight reflector 100 is hinged on the base 1 through the fixed hinge part of the dipped headlight reflector, and is hinged on the joint adjusting support 21 through the movable hinge part of the low beam reflector, and the high beam reflector 200 is hinged on the base 1 through the fixed hinge part of the high beam reflector, and is hinged on the joint adjusting support 21 through the movable hinge part of the high beam reflector.

Since the joint adjusting bracket 21 is slidably installed in the lamp housing 300 and the electric adjusting module 22 can drive the joint adjusting bracket 21 to move toward or away from the low beam reflector hinge, the rotation of the low beam reflector 100 with respect to the low beam reflector hinge and the rotation of the high beam reflector 200 with respect to the high beam reflector hinge can be realized by the driving of the joint adjusting bracket 21 by the electric adjusting module 22. That is, synchronous electrical adjustment of the irradiation positions of the low beam reflector 100 and the high beam reflector 200 is achieved.

Since the manual adjustment module 23 includes the adjustment screw 231 and the adjustment gear 232, and one end of the adjustment screw 231 is screw-fitted to the electric adjustment module 22, and the other end of the adjustment screw 231 is engaged with the adjustment gear 232, the adjustment screw 231 can be driven to rotate by screwing the adjustment gear 232, so that the electric adjustment module 22 is driven to move in the same direction as the joint adjuster bracket 21 by screw-fitting between the adjustment screw 231 and the electric adjustment module 22, and thus the electric adjustment module 22 and the joint adjuster bracket 21 move together, that is, the low-beam reflector 100 can be rotated with respect to the low-beam reflector fixed hinge, and the high-beam reflector 200 can be rotated with respect to the high-beam reflector fixed hinge. That is, synchronous manual adjustment of the irradiation positions of the low beam reflector 100 and the high beam reflector 200 is achieved.

As can be seen from the above, the light joint adjusting mechanism provided by the present disclosure can achieve synchronous adjustment of the low beam reflector 100 and the high beam reflector 200, thereby improving the adjustment efficiency. Also, since the low beam reflector 100 and the high beam reflector 200 are adjusted in synchronization, the relative position of the irradiation positions therebetween does not change (based on the last correct relative position), thereby ensuring the correct relative positions.

In this embodiment, the electric adjustment module 22 is used for adjusting the light of the driver in the vehicle, that is, the electric adjustment module 22 may be electrically connected to a driving computer, and the light adjustment is realized through an electric control button in the vehicle. The manual adjusting module 23 adjusts the light of the driver outside the vehicle, i.e. opens the engine cover and manually screws the adjusting gear 232 to adjust the light.

With continued reference to fig. 2, in the present embodiment, the electric adjustment module 22 includes a motor bracket 221 and a linear motor 222, the motor bracket 221 is slidably installed in the lamp housing 300, and the sliding direction of the motor bracket 221 is the same as the sliding direction of the joint adjustment bracket 21, the linear motor 222 is fixedly installed on the motor bracket 221, and the output shaft of the linear motor 222 is hinged to the joint adjustment bracket 21.

In the above implementation, the motor bracket 221 provides a mounting base for the linear motor 222, and the motor bracket 221 is slidably mounted in the lamp housing 300, so as to drive the linear motor 222 to move. The linear motor 222 is used for realizing the movement of the joint adjusting bracket 21 towards or back to the fixed hinge part of the low beam reflector through the driving shaft thereof, thereby realizing the synchronous electric adjustment of the light. Note that the axial direction of the output shaft of the linear motor 222 is the same as the sliding direction of the joint adjusting bracket 21.

Optionally, a sliding rail is disposed in the lamp housing 300, and the motor bracket 221 is slidably mounted on the sliding rail.

In this way, the sliding direction of the motor bracket 221 may be defined by the slide rail, thereby improving the sliding stability of the motor bracket 221.

Optionally, one end of the output shaft of the linear motor 222 is in a ball shape, a motor ball bowl 211 is arranged on the joint adjusting bracket 21, and the motor ball bowl 211 and the output shaft of the linear motor 222 are assembled together in a ball hinge manner.

In the above implementation manner, the output shaft of the linear motor 222 and the joint adjusting bracket 21 are assembled together in a spherical hinge manner, so that the degree of freedom between the output shaft of the linear motor 222 and the joint adjusting bracket 21 can be improved, and the influence on the driving of the joint adjusting bracket 21 due to low assembly precision (the axial direction of the output shaft of the linear motor 222 is different from the sliding direction of the joint adjusting bracket 21) is avoided.

Illustratively, the joint debugging support 21 and the motor support 221 can be slidably mounted on the same slide rail, so as to ensure that the sliding direction of the motor support 221 is the same as the sliding direction of the joint debugging support 21.

With continued reference to fig. 2, optionally, a rack 223 is disposed on the motor bracket 221, the rack 223 extends along the sliding direction of the motor bracket 221, and one end of the adjusting screw 231 is in threaded engagement with the rack 223.

In the above implementation manner, when the adjusting screw 231 is driven by the adjusting gear 232 to rotate, the motor support 221 can move along the axial direction of the adjusting screw 231 through the threaded fit between the adjusting screw 231 and the rack 223, so as to drive the linear motor 222 to move together, and the joint adjusting support 21 moves together under the driving of the linear motor 222, so as to achieve the synchronous manual adjustment of the light.

Fig. 3 is a schematic structural diagram of the joint-adjusting bracket, and referring to fig. 3, in the present embodiment, the joint-adjusting bracket 21 includes a low beam arm 212, a high beam arm 213 and a connecting arm 214, the low beam arm 212 and the high beam arm 213 are arranged in parallel, and the connecting arm 214 is connected between the low beam arm 212 and the high beam arm 213.

In this embodiment, the low beam arm 212 is used to provide a mounting base for the low beam hinge, the high beam arm 213 is used to provide a mounting base for the high beam hinge, and the connecting arm 214 connects the low beam arm 212 and the high beam arm 213 together to achieve the synchronous adjustment of the low beam reflector 100 and the high beam reflector 200.

Further, since the mounting positions of the low beam reflector 100 and the high beam reflector 200 are usually staggered, the mounting positions of the low beam reflector 100 and the high beam reflector 200 can be better adapted by disposing the low beam arm 212 and the high beam arm 213 separately.

Optionally, a stiffener 215 is provided on the connecting arm 214.

Thus, the structural strength of the connecting arm 214 can be improved to improve the reliability of the light joint debugging mechanism.

Illustratively, the reinforcing bars 215 may be truss structures, which may improve the structural strength of the reinforcing bars 215 by a lighter weight.

In the present embodiment, the low beam reflector hinge is a low beam driving shaft 216, the low beam driving shaft 216 is disposed on the low beam arm 212, and one end of the low beam driving shaft 216 is ball-shaped and protrudes from the low beam arm 212.

In the above-described implementation, the proximity lamp drive shaft 216 and the proximity lamp reflector 100 are assembled together by means of a ball joint, which improves the degree of freedom between the proximity lamp drive shaft 216 and the proximity lamp reflector 100, thereby improving the flexibility in adjusting the proximity lamp reflector 100.

Alternatively, the low beam reflector fixed hinge and the low beam reflector 100 may be assembled together by means of a ball joint, thereby further increasing the flexibility in adjusting the low beam reflector 100.

Fig. 4 is a schematic structural diagram of the movable hinge portion of the high beam reflector, and referring to fig. 4, the movable hinge portion of the high beam reflector is a high beam driving shaft 217, the high beam driving shaft 217 is disposed on the high beam support arm 213, and one end of the high beam driving shaft 217 is ball-shaped and protrudes out of the high beam support arm 213.

In the above implementation, the high beam drive shaft 217 and the high beam reflector 200 are assembled together in a spherical hinge manner, which can improve the degree of freedom between the high beam drive shaft 217 and the high beam reflector 200, thereby improving the flexibility in adjusting the high beam reflector 200.

Alternatively, the high beam reflector hinge and the high beam reflector 200 may be assembled together by a ball joint, thereby further increasing the flexibility in adjusting the high beam reflector 200.

Optionally, the middle portion of the high beam driving shaft 217 is inserted into the joint adjusting bracket 21 and is in threaded fit with the joint adjusting bracket 21, and the axial direction of the high beam driving shaft 217 is the same as the moving direction of the joint adjusting bracket 21.

In the above implementation, when the relative position between the irradiation position of the low beam mirror 100 and the irradiation position of the high beam mirror 200 is incorrect, the high beam mirror 200 can be adjusted by the high beam drive shaft 217 alone. During the realization, the high beam drive shaft 217 is twisted to the manual commentaries on classics to screw-thread fit between high beam drive shaft 217 and the joint adjusting support 21 to drive high beam drive shaft 217 axial displacement, thereby drive the removal of high beam lamp speculum 200, and then realize the regulation to high beam lamp speculum 200 alone.

Optionally, an end cap 218 is detachably mounted on the housing of the lamp, and the end cap 218 is disposed corresponding to the other end of the high beam driving shaft 217.

In the above implementation, the end cap 218 may function to protect the high-beam drive shaft 217 to prevent the high-beam drive shaft 217 from being touched by mistake.

The working principle of the light joint adjusting mechanism is briefly described as follows:

electric regulation: since the ganging bracket 21 is slidably mounted in the lamp housing 300 and the electric adjustment module 22 can drive the ganging bracket 21 to move toward or away from the low beam reflector fixed hinge, the rotation of the low beam reflector 100 relative to the low beam reflector fixed hinge and the rotation of the high beam reflector 200 relative to the high beam reflector 200 fixed hinge can be achieved by the driving of the ganging bracket 21 by the electric adjustment module 22. That is, synchronous electrical adjustment of the irradiation positions of the low beam reflector 100 and the high beam reflector 200 is achieved.

Manual adjustment: since the manual adjustment module 23 includes the adjustment screw 231 and the adjustment gear 232, and one end of the adjustment screw 231 is screw-fitted to the electric adjustment module 22, and the other end of the adjustment screw 231 is engaged with the adjustment gear 232, the adjustment screw 231 can be driven to rotate by screwing the adjustment gear 232, so that the electric adjustment module 22 is driven to move in the same direction as the joint adjuster bracket 21 by screw-fitting between the adjustment screw 231 and the electric adjustment module 22, and thus the electric adjustment module 22 and the joint adjuster bracket 21 move together, that is, the low-beam reflector 100 can be rotated with respect to the low-beam reflector fixed hinge, and the high-beam reflector 200 can be rotated with respect to the high-beam reflector fixed hinge. That is, synchronous manual adjustment of the irradiation positions of the low beam reflector 100 and the high beam reflector 200 is achieved.

Adjusting the high beam reflector individually: the high beam driving shaft 217 is manually screwed to drive the high beam driving shaft 217 to axially move through the screw-thread fit between the high beam driving shaft 217 and the joint adjusting bracket 21, so that the high beam reflector 200 is driven to move, and the high beam reflector 200 is adjusted independently.

As can be seen from the above, the light joint adjusting mechanism provided by the present disclosure can achieve synchronous adjustment of the low beam reflector 100 and the high beam reflector 200, thereby improving the adjustment efficiency. Also, since the low beam reflector 100 and the high beam reflector 200 are adjusted in synchronization, the relative position of the irradiation positions therebetween does not change (based on the last correct relative position), thereby ensuring the correct relative positions. In addition, since the high beam reflector 200 can be adjusted individually, even if there is a deviation in the relative position between the low beam reflector 100 and the high beam reflector 200, the relative position between the two can be corrected by adjusting the high beam reflector 200 individually.

The above description is intended to be exemplary only and not to limit the present disclosure, and any modification, equivalent replacement, or improvement made without departing from the spirit and scope of the present disclosure is to be considered as the same as the present disclosure.
