Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Referring to fig. 1, a shock wave energy density testing apparatus 10 can be used to detect the shock wave energy density of a drive 20. The driver 20 may be, for example, a shock wave therapy device. Specifically, the shock wave therapy apparatus is an air pressure ballistic shock wave therapy apparatus. The shock wave energy density test apparatus 20 is capable of determining the shock wave energy density of a treatment handle of an air ballistic shockwave treatment apparatus. It will be appreciated that the driver 20 is not limited to a shock wave treatment apparatus, and may be any other apparatus in which it is desirable to measure the energy density of shock waves.

The shock wave energy density testing device 10 comprises a limiting mechanism 100 and a detecting mechanism 300. The spacing mechanism 100 includes a support 110 and a mass 120 slidably coupled to the support 110. The mass 120 is movable along the length of the support 110 under impact of the driver 20. The detecting mechanism 300 is used for acquiring the moving distance D of the mass 120 on the support 110, and sending data of the moving distance D to an operation module (not shown), so that the operation module calculates the energy density of the shock wave received by the mass 120.

In the shock wave energy density testing apparatus 10, the mass block 120 is slidably connected to the support 110, and the mass block 120 can move along the length direction of the support 110 under the impact of the driver 20, so that the friction generated when the mass block 120 moves on the support 110 can be accurately predicted and calculated, so as to prevent unpredictable friction and collision generated during the movement of the mass block 120, further reduce errors possibly generated during the testing process, and facilitate the improvement of the accuracy of the testing result. In addition, the moving distance D of the mass block 120 on the support 110 is obtained by the detection mechanism 300, and the effective moving distance D is sent to the operation module to calculate the energy density of the shock wave borne by the mass block 120, so that errors possibly generated by manual visual inspection and calculation are avoided, and the accuracy of the test result is further improved.

It should be noted that the supporting member 110 may be a straight rod or a curved rod. When the support member 110 is a straight rod, the energy lost by friction when the mass 120 moves any distance on the support member 110 can be easily calculated through simple force analysis so as to calculate the shock wave energy density; when the support member 110 is a curved rod, as long as the shape, the placing position and the placing angle of the support member 110 are determined, the energy lost by friction when the mass 120 moves any distance on the support member 110 can be calculated by multiple measurements and the like, and the energy is recorded so as to calculate the shock wave energy density.

Specifically, when the supporting member 110 is a straight rod and the supporting member 110 is perpendicular to the horizontal plane, the calculation of the energy density of the shock wave received by the mass 120 becomes more convenient.

It should be noted that, for the convenience of understanding the moving distance D, taking fig. 1 as an example, the moving distance of the mass 120 on the support 110 is indicated by the arrow D.

In one embodiment, referring to fig. 1 and 3, the shock wave energy density testing apparatus 10 further comprises a base 400 coupled to the support member 110. Wherein the extension plane (the plane indicated by the arrow T shown in fig. 3) of the base 400 is parallel to the horizontal plane. The base 400 is perpendicular to the length direction of the support 110. Therefore, the support 110 perpendicular to the base 400 is also perpendicular to the horizontal plane, so that the distance that the mass 120 moves on the support 110 after being hit (i.e. the height of the mass moving in the vertical direction) and the energy loss between the mass 120 and the support 110 due to friction can be calculated, and the energy density of the shock wave borne by the mass 120 can be obtained according to the related calculation formula.

It should be noted that the extending direction of the supporting member 110 shown in fig. 1 is any direction indicated by the arrow a.

It should be further noted that, when the supporting member 110 is perpendicular to the horizontal plane, the impulse wave energy density borne by the mass 120 is calculated by the following formula:en is the shock wave energy density, E is the shock wave energy to which the mass 120 is subjected, and S is the area of the striking face of the driver 20 striking the mass 120. The formula for calculating the shock wave energy E borne by the mass 120 is as follows: e-mgh + μmgh; m is the mass of the mass 120; g is the acceleration of gravity and h is the movement of the mass 120 on the support 110Height (i.e., distance of movement D); μ is the friction factor between the mass 120 and the support 110.

Specifically, when the driver 20 is a shock wave therapy apparatus, S is the surface area of the impact head of the shock wave therapy apparatus, and the calculation formula of S is:pi is the circumference ratio and d is the diameter of the treatment head.

In one embodiment, referring to fig. 3, the shock wave energy density testing apparatus 10 further includes a level 500 and an adjustment member 600. The level 500 is mounted to the base 400. The adjusting member 600 can adjust the levelness of the base 400 according to the level 500. Therefore, the operator can accurately adjust the levelness of the base 400 according to the levelness displayed on the level gauge 500, so that the inclination error of the device is eliminated, and the accuracy of the detection result is further improved.

It should be noted that the position relationship between the level 500 and the base 400 is: when the level 500 is level, the base 400 is also level.

Further, referring to fig. 3, a mounting portion (not shown) is disposed on the base 400. The level 500 is at least partially embedded in the mounting portion. Thus, the level gauge 500 cannot fall off the base 400 in the process of adjusting the base 400, and the efficiency and accuracy of adjusting the levelness of the base 400 are improved.

The mounting portion may be integrally formed with the base 400. At this moment, the installation department can be the through-hole of seting up on the base 400, this through-hole shape and spirit level 500 adaptation to make spirit level 500 can stably inlay establish with the installation department, and then make spirit level 500 can be stably connected with base 400. Of course, the mounting portion may be any connecting structure that can stably connect the level 500 and the base 400.

It will also be appreciated that the adjustment member 600 may be an adjustment stud, adjustment block, or the like that is capable of adjusting the position of the base 400. Meanwhile, the number of the regulating member 600 may be one, two or more.

Specifically, referring to fig. 3, the adjusting member 600 is an adjusting stud. The number of the regulating members 600 is four. The base 400 is square. Four corners of the base 400 are respectively provided with mounting screw holes (not shown). The four adjusting members 600 are respectively screwed to the four mounting screw holes. Therefore, the levelness of the base 400 can be adjusted by adjusting the heights of the adjusting studs in the four mounting screw holes of the base 400, so that the efficiency of adjusting the levelness of the base 400 is improved.

In one embodiment, referring to fig. 1, the detecting mechanism 300 includes a detector 310 and a positioning member 320 fixedly connected to the detector 310. The positioning member 320 is fixedly connected to an end of the supporting member 110 away from the base 400. The detector 310 can acquire the moving distance of the mass 120.

It can be seen that the position of the detector 310 is fixed, so as to ensure that the detector 310 obtains the moving distance D of the mass 120 during the sliding of the mass 120 along the support 110.

It is understood that the moving distance D of the mass 120 can be measured by, but not limited to: directly measuring the distance between the initial position and the moved-to-high position of the mass 120 to obtain the moving distance D of the mass 120; or measuring the distance between the mass 120 and the detector 310 when the mass 120 is at the initial position and the distance between the mass 120 and the detector 310 when the mass 120 moves to the high point position, and subtracting the two distances to obtain the moving distance D of the mass 120.

It should be noted that the initial position is a position on the support member 110 when the mass 120 is hit by the driver 20; the high position is a position on the support member 110 when the mass 120 moves to the highest point (velocity position 0) along the length direction of the support member 110 after being hit by the driver 20.

Further, referring to fig. 1 and 2, the detector 310 may be, but not limited to, an ultrasonic range finder, an infrared range finder, or other devices capable of measuring distance.

Specifically, the detector 310 is an ultrasonic range finder.

In one embodiment, referring to fig. 1 and 2, the shock wave energy density testing apparatus 10 further includes a display 700. The display 700 is electrically connected to the detecting mechanism 300 to display the maximum value of the moving distance D acquired by the detecting mechanism 300. It is understood that the display 700 can visually display the maximum value of the moving distance D acquired by the detecting mechanism 300 for the convenience of the tester to observe and record.

Further, the detecting mechanism 300 is electrically connected to an operation module (not shown). The calculation module stores the calculation method of the shock wave energy density, sorts the moving distances D acquired by the detection mechanism 300, and brings the maximum value of the moving distances D into the calculation method to obtain the numerical value of the shock wave energy density.

In one embodiment, referring to fig. 1 and 2, the display 700 is electrically connected to the computing module for displaying the shockwave energy density calculated by the computing module. Therefore, the display 700 directly displays the calculated shock wave energy density in the form of a numerical value on the display 700.

It should be noted that the display 700 is not limited to the above-mentioned parameters, and may also display other parameters, such as: shock wave energy (E), and the like.

In one embodiment, referring to fig. 1 and 2, the mass 120 includes a slider 121 and a striking block 122. The slider 121 is slidably coupled to the support 110. The striking block 122 is fixedly connected to the slider 121 and can slide with the slider 121 relative to the support 110. The striking block 122 can move along the length direction of the support 110 with the slider 121 under the striking of the driver 20.

Therefore, the striking block 122 is slidably connected with the support 110 through the sliding block 121, so that the sliding block 121 is not in direct contact with the driver 20, the sliding block 121 can be better protected, and the service life of the sliding block 121 is prolonged.

Further, the striking block 122 is detachably connected to the slider 121. Therefore, the striking block 122 may be made of a striking resistant and low cost material, thereby reducing the manufacturing cost of the device. In addition, after a plurality of tests, the striking block 122 or the sliding block 121 can be replaced respectively according to actual needs, which is beneficial to reducing the maintenance cost of the equipment.

It is understood that the support member 110 may have a guide rail 111 mounted thereon. The guide rail 111 is slidably fitted with the slider 121. When the driver 20 strikes the striking block 122, the striking block 122 drives the slider 121 to move together along the length direction of the guide rail 111. When the extension plane of the base 400 is horizontal and the supporting member 110 is perpendicular to the base 400, the striking block 122 can drive the sliding block 121 to move along the guide rail 111 in the vertical direction under the striking of the driver 20. Accordingly, it is understood that the friction force generated during the movement of the mass 120 can be further reduced and the error due to the additional friction force can be reduced by the cooperation between the guide rail 111 and the slider 121. In this case, μ in the formula for calculating the shock wave energy is a friction factor between the guide rail 111 and the slider 121.

Specifically, in the present embodiment, the guide rail 111 is a linear guide rail.

In one embodiment, referring to fig. 1, the shock wave energy density testing apparatus 10 further comprises a clamp 800. The clamping member 800 is connected to the supporting member 110. Clamp 800 is used to clamp drive 20. The mass 120 is located between the sensing mechanism 300 and the driver 20 and reciprocates between the sensing mechanism 300 and the driver 20.

It can be seen that after the mass 120 is hit by the driver 20, the detection mechanism 300 and the driver 20 have enough space between them for the mass 120 to slide.

Referring to fig. 1 and 2, a method for measuring shock wave energy density is provided, which is suitable for the shock wave energy density measuring apparatus 10. The method for testing the energy density of the shock wave comprises the following steps: mounting the driver 20 on the shock wave energy density testing apparatus 10 and disposing the output end of the driver 20 toward the support 110; actuating the driver 20 strikes the mass 120; the mass 120 is driven to move along the length of the support 110 towards the extreme position; controlling the detection mechanism 300 to detect the mass block 120 every preset time to obtain a moving distance D of the mass block 120 on the support 110; based on the obtained moving distance D, the energy density of the shock wave received by the mass 120 is calculated. Wherein, when energized, the driver 20 strikes the mass 120 at a frequency that causes it to move along the length of the support 110.

In this embodiment, the driver 20 strikes the mass 120 at a frequency of 1 Hz. At which time the impact energy of the driver 20 to the mass block 120 is maximized.

The above-mentioned extreme position is a position on the support member 110 when the mass 120 moves to the maximum point (speed is 0) along the length direction of the support member 110 after being hit by the driver 20.

It should be noted that the "preset time" is only required to satisfy the condition that the highest height can be acquired within 300 ms. In the present embodiment, the "preset time" is 5 ms. I.e., every 5ms, the detection mechanism 300 detects the position of the mass 120 to improve the detection accuracy.

In one embodiment, referring to fig. 1, the step of calculating the energy density of the shock wave received by the mass 120 according to the obtained moving distance D includes: the acquired moving distances D are sorted, the maximum value of the moving distances D is acquired, and the energy density of the shock wave borne by the mass block 120 is calculated according to the maximum value of the moving distances D.

Further, referring to fig. 1, the step of calculating the energy density of the shock wave received by the mass 120 according to the obtained moving distance D includes: according to the moving distance D, the friction force between the mass 120 and the support 110 is corrected to calculate the energy density of the shock wave received by the mass 120.

In one embodiment, the formula for calculating the energy density of the shock wave received by the mass 120 when the support 110 is in the vertical state is as follows:en is the shock wave energy density, E is the shock wave energy to which the mass 120 is subjected, and S is the area of the striking face of the driver striking the mass 120. The formula for calculating the shock wave energy E borne by the mass 120 is as follows: e-mgh + μmgh; m is the mass of the mass 120; g is the gravitational acceleration, h is the moving height of the mass 120 on the support; μ is the friction factor between the mass 120 and the support 110.

Specifically, when the driver 20 is a shock wave therapy apparatus, S is the surface area of the impact head of the shock wave therapy apparatus, and the calculation formula of S is:pi is the circumference ratio and d is the diameter of the treatment head.

It should be noted that, when the support 110 and the mass 120 are slidably fitted to the slider 121 through the guide rail 111, μ in the formula for calculating the shock wave energy is a friction factor between the guide rail 111 and the slider 121.

Therefore, in the shock wave energy density testing method, the mass block 120 is slidably connected to the support 110, and the driver 20 strikes the mass block 120, so that the mass block 120 moves along the length direction of the support 110, and the friction generated when the mass block 120 moves on the support 110 can be accurately predicted and calculated, so that unpredictable friction and collision generated in the moving process of the mass block 120 can be prevented, further errors possibly generated in the testing process can be reduced, and the accuracy of the testing result can be improved. In addition, the detection mechanism 300 is used for acquiring the moving distance D of the mass block 120 on the support 110, and sending the effective moving distance D to the operation module, and the operation module corrects the friction force between the mass block 120 and the support 110 according to the moving distance D to calculate and obtain the energy density of the shock wave borne by the mass block 120, so that errors possibly generated by manual visual inspection and calculation are avoided, the accuracy of the test result is further improved, and automatic data acquisition and analysis are realized.

In the present invention, unless otherwise expressly stated or limited, the terms "connected," "secured," "mated" and the like are to be construed broadly and can, for example, be fixedly connected, releasably connected, or integral; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
