Description

Technical Field

[0001] The present invention relates to the technical field of special detection equipment for vehicle seats, and particularly to an auxiliary device for the static strength test of vehicle seat headrests. Background Art

[0002] Vehicle seats are given the same important status as the entire vehicle. Their safety and comfort directly affect the overall vehicle quality. In recent decades, countries have carried out extensive research on the detection methods of vehicle seats themselves. However, to this day, the most widely used and applied method is still based on the seat H-point inspection method, that is, the strength of most seats is based on the seat H-point.

[0003] However, due to the inconsistency of each seat model, when conducting seat strength tests, complex adjustments need to be made to the test equipment to ensure that the force application point contacts the H-point properly. Especially for the static strength test of the headrest, due to its special position, the process of aligning it with the H-point is particularly complex, greatly reducing the test efficiency and restricting the effective development and progress of test technology. Summary of the Invention

[0004] To solve the above problems, the present invention provides an auxiliary device for the static strength test of vehicle seat headrests to improve the corresponding efficiency between the test device and the seat H-point, that is, to improve the test efficiency and promote the progress of test technology.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] An auxiliary device for the static strength test of vehicle seat headrests, which is characterized in that: it includes a bottom plate and a support plate vertically installed on the bottom plate. The bottom of the bottom plate has a guiding convex rib arranged along its length direction, and locking holes are provided on both sides of the guiding convex rib. A laser generator is provided on the support plate. The laser generator is arranged parallel to the bottom plate, and its laser emission port is located on the side away from the support plate. The support plate is provided with an adjustment structure for driving the laser generator to move along the height direction and width direction of the support plate.

[0007] With the above solution, when in use, the device is placed on the test bench. By moving it back and forth and cooperating with the adjustment structure, three-axis adjustment of the laser emitter is achieved, so that the laser can quickly align with the H-point of the seat to be tested. And the test device is synchronously adjusted according to the adjustment amount, so that the force application part of the test device on the headrest can quickly correspond to the seat H-point, and the next step of the experiment can be carried out, which can adapt to the static strength tests of headrests of different seat models.

[0008] Preferably, the adjustment structure includes a vertical lead screw and a vertical guide rod arranged in parallel along the height direction of the support plate. A vertical mounting block is slidably engaged with the vertical guide rod, and a vertical nut seat is threadedly engaged with the vertical lead screw. A transfer plate connected to the nut seat is fixed on the vertical mounting block;

[0009] The transfer plate is provided with a horizontal lead screw and a horizontal guide rod arranged along the width direction of the support plate. A horizontal nut seat is threadedly engaged with the horizontal lead screw, and a horizontal mounting block is slidably engaged with the horizontal guide rod. A mounting plate connected to the horizontal nut seat is fixed on the vertical mounting block. Both the mounting plate and the transfer plate are parallel to the support plate, and the laser generator is located on the mounting plate. The adjustment structure adopting the above scheme is beneficial to improving the adjustment smoothness, and has a simple structure, is easy to implement, and has a low economic cost.

[0010] Preferably, the mounting plate is provided with a fixed seat parallel to the bottom plate. The fixed seat is in an "L" shape and has a first abutting surface and a second abutting surface perpendicular to each other. The first abutting surface is parallel to the support plate. One side of the laser generator is closely attached to the second abutting surface, and the rear end is closely attached to the first abutting surface. Adopting the above scheme, by the way of abutting on two surfaces, it is ensured that the laser generator is installed in a horizontal posture, reducing experimental errors.

[0011] Preferably, handwheels A and B are respectively arranged at the end parts of the vertical lead screw and the horizontal lead screw. Adopting the above scheme, through handwheel adjustment, the device cost is further reduced, and at the same time, the operability of the device is improved, and the experimenter can perform quick manual adjustment according to needs.

[0012] Preferably, the locking hole is a strip-shaped hole. Adopting the above structure, infinite adjustment in the front-rear direction of the bottom plate can be realized in cooperation with the installation groove of the experimental table, reducing experimental errors.

[0013] Preferably, the bottom plate is in a "T" shape, and symmetrically arranged supporting ears are provided on both sides of its front end. The locking holes are located on the supporting ears, and the guiding convex rib is located in the middle of the bottom plate. Adopting the above scheme is beneficial to improving the stability when the bottom plate is fixed and the smoothness of the front-rear sliding, preventing the device from tipping or being difficult to move due to the center of gravity deviation.

[0014] Preferably, at least one side of the left and right of the support plate has a vertical reference surface, and a pointer A extending towards the vertical reference surface is provided on the vertical mounting block or the vertical nut seat or the transfer plate;

[0015] At least one side of the upper and lower of the transfer plate has a horizontally arranged horizontal reference surface, and a pointer B extending towards the horizontal reference surface is provided on the horizontal nut seat or the horizontal mounting block or the mounting plate.

[0016] By adopting the above scheme, scales can be marked on the vertical reference plane and the horizontal reference plane, or a steel ruler can be fixed, etc. Then, by recording the scale indicated by the pointer, the moving distance parameter can be quickly calculated, and the calculated parameter can be assigned to the experimental device, thereby improving the efficiency of the experimental device for aligning the H point.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] By using the static strength test auxiliary device for automotive seat headrests provided by the present invention and adopting the method of reference and comparison, the adjustment parameters for aligning the H point of the seat to be tested can be obtained through the auxiliary device, and then this parameter is given to the experimental device, so that the experimental device can quickly align the H point of different models of seats, thereby improving the experimental efficiency and promoting the development of experimental technology.

[0022] The present invention will be further described below in conjunction with the embodiments and the drawings.

[0023] Referring to Figures 1 to 3 the static strength test auxiliary device for automotive seat headrests shown, it mainly includes a bottom plate 1 and a support plate 2 that are perpendicular to each other and both have a plate-like structure. The bottom plate 1 is horizontally arranged, the support plate 2 is vertically fixed on the bottom plate 1 and is fastened by a triangular rib plate 5. The bottom of the bottom plate 1 has a guiding rib 10 arranged along its length direction, and locking holes 11 are provided on both sides of the bottom plate 1. A laser generator 3 is detachably provided on the support plate 2. The laser generator 3 is arranged parallel to the bottom plate 1, and its laser emission port is located on the side away from the support plate 2. At the same time, an adjustment structure is provided on the support plate 2 to enable the laser generator 3 to move along the height direction and width direction of the support plate 2. By moving the bottom plate 1 back and forth and driving by the adjustment structure, three-axis movement of the laser emission line of the laser generator 3 can be realized, so that it can quickly align the H point of the seat to be tested.

[0024] The specific structure of the adjustment structure is shown in the figure. It mainly includes a vertical lead screw 20 and a vertical guide rod 21 that are arranged in parallel along the height direction of the support plate 2. The vertical lead screw 20 and the vertical guide rod 21 are located on the front side of the support plate 2. The upper and lower ends of the vertical lead screw 20 are rotatably fixed on the support plate 2. A vertical nut seat 200 that is threadedly engaged with the vertical lead screw 20 is provided on the vertical lead screw 20. A vertical mounting block 210 that is slidably engaged with the vertical guide rod 21 is provided on the vertical guide rod 21. The front side of the vertical mounting block 210 is fixedly installed with a transfer plate 22, and the transfer plate 22 is also fixedly connected to the nut seat 200. In this way, when the vertical lead screw 20 rotates, the transfer plate 22 can be driven to perform vertical lifting movement through the vertical nut seat 200.

[0025] The length direction of the transfer plate 22 is perpendicular to the height direction of the support plate 2. A horizontal lead screw 23 that is arranged along the width direction of the support plate 2 (i.e., the length direction of the transfer plate 22) and a horizontal guide rod 24 that is arranged in parallel with the horizontal lead screw 23 are provided thereon. Similarly, the two ends of the horizontal lead screw 23 are rotatably fixed to the transfer plate 22. A horizontal nut seat 230 that is threadedly engaged with the horizontal lead screw 23 is provided on the horizontal lead screw 23. A horizontal mounting block 240 that is slidably engaged with the horizontal guide rod 24 is provided on the horizontal guide rod 24. An installation plate 25 is provided on the front side of the horizontal mounting block 240. The installation plate 25 is arranged vertically and is parallel to both the transfer plate 22 and the support plate 2. The laser generator 3 is fixedly provided on the installation plate 25.

[0026] In this embodiment, to ensure that the laser generator 3 can be quickly installed to a horizontal posture, improve the installation efficiency, and ensure the measurement accuracy, etc., a fixed seat 4 is fixedly provided on the front side of the installation plate 25, as Figure 3 shown. The fixed seat 4 is generally in an "L" shape. It has a first abutting surface 40 that is parallel to the installation plate 25 and a second abutting surface 41 that is perpendicular to the first abutting surface 40. And the second abutting surface 41 is also perpendicular to the bottom plate 1. When installing the laser generator 3, after the rear end face and one side face of the laser generator 3 are respectively closely attached to the first abutting surface 40 and the second abutting surface 41, and then it is locked, it can be ensured that the emission direction of the laser generator 3 remains horizontal and is in the direct front of the support plate 2.

[0027] Considering factors such as the operability and labor-saving of the adjustment, a handwheel A 26 and a handwheel B 27 are respectively fixedly connected to the vertical lead screw 20 and the horizontal lead screw 23.

[0028] In this embodiment, the bottom plate 1 is generally in a "T" shape. There are symmetrically arranged supporting lugs 12 on both sides of its front end. The locking holes 11 are located within the supporting lugs 12 and are strip-shaped holes arranged along the length direction of the bottom plate 1. The cam 10 is located in the middle of the bottom plate 1, and the supporting plate 2 is located at the rear end of the bottom plate 1. Adopting such a distribution structure is beneficial to improving the overall center of gravity stability of the device. Even when the bottom plate 1 is not fixed, the device will not accidentally tilt or topple. Moreover, the locking holes 11 with a strip-shaped hole structure can be better fixed to the assembly groove on the experimental table through bolts for stepless adjustment.

[0029] In addition, in order to quickly correspond the adjustment result of this device to the experimental device, a recording or indicating structure is correspondingly provided on the device. For example, at least one of the left and right sides of the supporting plate 2 is a vertically smooth plane, and this vertically smooth plane constitutes a vertical reference plane 2a. Any one of the vertical mounting block 210, the vertical nut seat 200, and the adapter plate 22 has a pointer A2b extending towards the vertical reference plane 2a. As shown in the figure, in this embodiment, the left side of the supporting plate 2 is configured as the vertical reference plane 2a, and the vertical nut seat 200 has a pointer A2b extending towards the supporting plate 2 and located outside the vertical reference plane 2a.

[0030] Similarly, at least one of the upper and lower sides of the adapter plate 22 is a horizontally arranged smooth surface, and its horizontally arranged smooth surface constitutes a transverse reference plane 2c. The transverse nut seat 230, the transverse mounting block 240, or the mounting plate 25 has a pointer B2d extending towards the transverse reference plane 2c. Specifically, as shown in the figure, in this embodiment, the upper side of the adapter plate 22 is configured as the transverse reference plane 2c, and the transverse nut seat 230 has a pointer B2d extending towards the adapter plate 22. The pointer B2d is at least partially located above the transverse reference plane 2c. During actual use, scales can be directly marked on the vertical reference plane 2a and the transverse reference plane 2c, or a steel ruler can be fixed on them. In this way, during the adjustment process, only the corresponding scales before and after the corresponding pointer need to be recorded to obtain the adjustment parameters of the device. When applying this parameter to the experimental device, it can quickly align with the seat H point, achieving the purpose of improving the experimental efficiency.

[0031] Finally, it should be noted that the above description is only the preferred embodiment of the present invention. Under the inspiration of the present invention, those of ordinary skill in the art can make various similar representations without violating the purpose and claims of the present invention. Such transformations all fall within the protection scope of the present invention.
