[0047] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0048] like Figure 1 As shown in the embodiment of this application, a test fixture is proposed, including: a lower base plate 11, an upper base plate 12, and a clamping mechanism 14; a connector is provided on the lower base plate 11 for connecting to a preset mounting mechanism; the upper base plate 12 is connected to the lower base plate 11 through an adjustment mechanism 13, so that the position of the upper base plate 12 relative to the lower base plate 11 can be adjusted by the adjustment mechanism 13; the clamping mechanism 14 is detachably disposed on the top surface of the upper base plate 12 away from the lower base plate 11, and at least a portion of the clamping mechanism 14 protrudes in the direction away from the top surface of the upper base plate 12, so that a mounting cavity 15 capable of accommodating a target part is formed between the protruding portion of the clamping mechanism 14 and the top surface of the upper base plate 12.

[0049] The testing fixture provided in this embodiment includes a lower base plate 11, an upper base plate 12, and a clamping mechanism 14. The target part is detachably mounted on the upper base plate 12 via the clamping mechanism 14, enabling rapid assembly and disassembly of the target part without damaging its own structure. The clamping mechanism 14 presses the target part tightly onto the upper base plate 12. The clamping mechanism 14 mainly relies on pressure to fasten the target part, so it does not have requirements on the shape or size of the target part, and can adapt to different target part models, improving the compatibility of the testing fixture with different target part models. The lower base plate 11 is mounted on a preset mounting mechanism, and the upper base plate 12 is adjustablely mounted on the lower base plate 11 via an adjustment mechanism 13. The position of the upper base plate 12 relative to the lower base plate 11 can be adjusted by the adjustment mechanism 13, that is, the position of the upper base plate 12 relative to the preset mounting mechanism can be adjusted, thereby adjusting the position of the target part relative to the preset mounting mechanism, realizing rapid testing from multiple angles and directions, reducing the difficulty of installing and adjusting the target part, and improving the testing efficiency of the target part.

[0050] Furthermore, during testing, the target component is mounted on a pre-set mounting mechanism using a test fixture to verify its performance and safety on the mechanism. In some examples, the target component can be a radar, or other devices used for measuring distance and position such as sensors, detection devices, and positioning devices; the pre-set mounting mechanism can be a vehicle, or other movable objects such as robots or toys. As a preferred embodiment, the target component is a radar, and the pre-set mounting mechanism is a vehicle. The radar is mounted on the vehicle using the test fixture, and the position of the radar is adjusted by adjusting the test fixture to test the radar.

[0051] Furthermore, a pre-installed mounting mechanism is provided on the vehicle roof, and a lower base plate 11 is installed on the vehicle roof. The lower base plate 11 has several mounting points, which are fixed to the vehicle's pre-installed mounting mechanism by fasteners or clamps to adapt to the roof structure of different vehicle models. It is understandable that during installation, a suitable lower base plate 11 can be selected according to the size and shape of the vehicle roof.

[0052] It is understandable that the radar is clamped and fixed by the clamping mechanism 14. Only the clamping mechanism 14 needs to be fixed on the upper base plate 12. There is no need to set corresponding mounting holes on the upper base plate 12 according to different radar models. This reduces the manufacturing and processing difficulty of the test fixture. Before the clamping mechanism 14 is fully locked, the position of the radar on the upper base plate 12 can be moved and adjusted slightly. The radar does not need to be completely disassembled during adjustment. The installation and adjustment of the radar is simple and convenient.

[0053] like Figure 2 As shown, in one feasible embodiment, the clamping mechanism 14 includes: an adjusting pad 141 and a pressure plate 142; the adjusting pad 141 is detachably mounted on the upper base plate 12; the pressure plate 142 includes a contact section and a connecting section, the contact section protrudes in a direction away from the top surface of the upper base plate to form a mounting cavity 15; the connecting section is connected to the upper base plate 12 by a connector.

[0054] Furthermore, the shape of the mounting cavity 15 formed by the selected pressure plate 142 and the upper base plate 12 is adapted to the shape of the target part, so as to reduce the gap between the pressure plate 142 and the target part and ensure the stability of the pressure plate 142 in pressing and fixing the target part.

[0055] In some examples, the mounting cavity 15 can be designed in a standardized shape to fit the mainstream target part models on the market. When changing the target part to be tested, it is not necessary to completely remove and replace the pressure plate 142, making the installation and replacement of the target part to be tested simpler.

[0056] like Figures 2 to 4 As shown, in one feasible embodiment, multiple mounting points corresponding to the second locking member 145 are provided on the upper base plate 12. The second locking member 145 passes through the adjusting pad 141 and is threadedly connected to the mounting points of the upper base plate 12 to achieve fixation. When it is necessary to adjust the position of the adjusting pad 141, the position of the adjusting pad 141 can be adjusted by connecting the second locking member 145 with different mounting points.

[0057] like Figures 2 to 4As shown, in one feasible embodiment, the pressing mechanism 14 further includes: a first adjusting hole 143 and a first locking member 144; a plurality of mounting holes corresponding to the first locking member 144 are provided on the upper base plate; the first adjusting hole 143 is elongated and disposed on the adjusting pad 141; the first locking member 144 passes through the pressure plate 142 and the first adjusting hole 143 and is threadedly connected to the mounting hole on the upper base plate 12. Furthermore, the first locking member 144 can move within the first adjusting hole 143, that is, it can connect with different mounting holes on the upper base plate 12 within the range of the first adjusting hole 143. Under the condition that the position of the adjusting pad 141 is fixed, the relative position of the pressure plate 142 with respect to the adjusting pad 141 can be finely adjusted, increasing the adjustable range of the pressure plate.

[0058] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the adjusting mechanism 13 includes: a locking plate 131 and a guide locking member 133; the locking plate 131 is connected to the lower base plate 11 and extends along the outer edge of the lower base plate 11 towards the outer edge of the upper base plate 12; a guide hole 132 is provided on the locking plate 131; the guide hole 132 extends towards the upper base plate 12. The guide locking member 133 is movably disposed in the guide hole 132 and is threadedly connected to the upper base plate 12. By pressing the locking plate 131 with the guide locking member 133, the position of the upper base plate 12 relative to the lower base plate 11 is fixed.

[0059] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the adjustment mechanism 13 includes two parts, with one adjustment mechanism 13 arranged at each end of the upper and lower base plates, which helps to ensure the synchronicity and consistency of the adjustment at both ends of the upper base plate 12; the locking plate 131 is provided with a guide hole 132, the locking plate 131 is fixed on the lower base plate 11, and the guide locking member 133 is threadedly connected to the upper base plate 12. The guide locking member 133 passes through the guide hole 132 and can slide along the guide hole 132, so as to adjust the position of the upper base plate 12 relative to the lower base plate 11, thereby adjusting the position of the target part.

[0060] It is understandable that when adjusting the upper base plate 12, visual or angle scale design can be used to assist in positioning to ensure the precise adjustment of the position of the upper base plate 12, thereby achieving precise adjustment of the target part's position.

[0061] like Figure 2 As shown, in one possible embodiment, the guide hole 132 is arc-shaped. The guide hole 132 guides the upper base plate 12 to rotate slightly relative to the lower base plate 11.

[0062] like Figure 2 and Figure 3As shown, in one feasible embodiment, the lower base plate 11 is rectangular, and the locking plate 131 is disposed at the top corner of the first side of the lower base plate 11; the upper base plate 12 is rectangular, and the upper base plate 12 is disposed above the lower base plate 11, and the guide locking member 133 is disposed at the top corner of the first side of the upper base plate 12.

[0063] In this technical solution, when both the lower base plate 11 and the upper base plate 12 are rectangular, the adjustment mechanism 13 is arranged at the two apex corners on the same side of the upper base plate 12 so that the upper base plate 12 has a larger rotatable space, thereby increasing the angle adjustment range of the upper base plate 12.

[0064] It is understandable that when the rotation axis of the upper base plate 12 is close to the edge of the first side of the upper base plate 12, the opening angle of the second side of the upper base plate 12 is larger, and the adjustable angle range of the upper base plate 12 is larger. Compared to the first side, the clamping mechanism can be positioned closer to the second side to achieve a larger rotation angle. The first side and the second side are opposite sides. Figure 2 .

[0065] In some examples, when the upper base plate 12 is of other shapes, the guide locking member 133 is provided at the edge of the upper base plate 12, so that the rotation axis of the upper base plate 12 is away from the center position of the upper base plate 12.

[0066] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the testing fixture further includes a bracket 16, which is disposed on the top surface of the lower base plate 11. The bracket 16 includes a positioning part, which is disposed perpendicular to the lower base plate 11 and protrudes towards the upper base plate 12. The second side and the first side of the lower base plate 11 are opposite sides of the lower base plate 11. The number of brackets 16 can be set to two, with each bracket 16 located at one of the two apex corners of the second side of the lower base plate 11.

[0067] In this technical solution, the bracket 16 is vertically mounted on the top surface of the lower base plate 11 and protrudes upward. The bracket 16 and the adjustment mechanism 13 are located on both sides of the pressing mechanism 14, so that the bracket 16 provides limiting support below the upper base plate 12, so that the upper base plate 12 and the lower base plate 11 remain parallel when the upper base plate 12 is in contact with the bracket 16. This serves as a positioning structure for the starting position of the adjustment of the upper base plate 12, which facilitates the determination of the subsequent rotation adjustment angle of the upper base plate 12 and helps to improve the accuracy of the angle adjustment of the upper base plate 12.

[0068] Specifically, the support 16 is L-shaped.

[0069] like Figures 1 to 3As shown, in one feasible implementation, the test fixture further includes: an adjusting support column 17, which passes through the upper base plate and is threadedly connected to the upper base plate, so that the connection position between the adjusting support column 17 and the upper base plate 12 is adjustable. By rotating the adjusting support column 17, the adjusting support column can move up and down relative to the upper base plate 12 to contact the top surface of the lower base plate 11.

[0070] In this technical solution, the adjusting support column 17 is threadedly connected to the upper base plate 12. By turning the adjusting support column 17, the length of the bottom end of the adjusting support column 17 extending from the upper base plate 12 can be changed, so that the bottom end of the adjusting support column 17 can abut against the lower base plate 11, thereby providing auxiliary support for the upper base plate 12. This prevents the target part from sliding down under pressure and its own gravity after the upper base plate 12 is raised by the adjusting mechanism 13, thereby improving the stability and reliability of the upper base plate 12 after adjustment.

[0071] like Figures 1 to 4 As shown, in one feasible embodiment, the test fixture further includes: a second adjustment hole 18, a first corner block 19, a third locking member 20, a third adjustment hole 21, a second corner block 22, and a fourth locking member 23; the second adjustment hole 18 is disposed on the top surface of the upper base plate 12 and extends along a first direction; the first corner block 19 is slidably disposed within the second adjustment hole 18; the third locking member 20 passes through the second adjustment hole 18 and is threadedly connected to the first corner block 19 to press the first corner block 19 tightly onto the upper base plate 12;

[0072] The third adjustment hole 21 is provided on the top surface of the upper base plate 12 and extends along the second direction. The second corner block 22 is slidably provided in the third adjustment hole 21. The fourth locking member 23 passes through the third adjustment hole 21 and is threadedly connected to the second corner block 22 to press the second corner block 22 tightly onto the upper base plate 12. The first direction and the second direction are perpendicular to each other, and the first corner block 19 and the second corner block 22 are located on both sides of the pressing mechanism 14.

[0073] In this technical solution, a first corner block 19 and a second corner block 22 are provided on the top surface of the upper base plate 12. The position of the first corner block 19 is adjusted through a second adjustment hole 18 cooperating with a third locking member 20, allowing the first corner block 19 to move in a first direction. The position of the second corner block 22 is adjusted through a third adjustment hole 21 cooperating with a fourth locking member 23, allowing the second corner block 22 to move in a second direction. By adjusting the positions of the first corner block 19 and the second corner block 22, small-amplitude position adjustments and limits on the target part can be achieved in both the first and second directions. Furthermore, by using a pressure plate, the target part can be limited in the vertical direction, where the first direction, the second direction, and the vertical direction are mutually perpendicular. That is, by using the first corner block 19 and the second corner block 22 in conjunction with the pressure plate, the position of the target part can be precisely limited, preventing slippage in all directions, further improving the stability of the target part after fixation, and achieving precise positioning of the target part on the upper base plate 12.

[0074] Preferred, refer to Figure 3 There are two first corner blocks 19 and two second corner blocks 22, which are installed opposite each other on the same side of the upper base plate 12. After the target part is installed in place, both first corner blocks 19 abut against the surface of the target part in the first direction, and both second corner blocks 22 abut against the surface of the target part in the second direction. This achieves the limiting of the target part in the first and second directions.

[0075] In one feasible implementation, the lower base plate 11 and the preset mounting mechanism are slidably connected.

[0076] In one feasible implementation, the pre-installed mounting mechanism located on the roof includes a guide rail and a lower base plate mounting position. The lower base plate mounting position and the guide rail are slidably connected. The lower base plate 11 of the test fixture is threadedly connected to the lower base plate mounting position. By sliding the lower base plate mounting position on the guide rail, the entire test fixture slides on the guide rail, thereby achieving a sliding connection between the lower base plate and the pre-installed mounting mechanism. This allows for a significant adjustment of the target part's position, enabling the target part to quickly reach the vicinity of the designated position. Then, the fixture is used to precisely adjust the position of the target part, ensuring the efficiency of adjusting the position of the target part under test.

[0077] Furthermore, the lower base plate mounting position is mounted on the slider of the guide rail via a connector. The slider is equipped with a locking mechanism to lock the final position of the tooling on the guide rail, ensuring the overall stability of the tooling.

[0078] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0079] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
