[0036] To make the objectives, technical solutions and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts shall fall within the scope of protection of this application.

[0037] The following disclosure provides many different embodiments or examples for implementing different structures of this application. To simplify the disclosure of this application, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit this application. In addition, this application may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0038] For ease of description, spatially relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms such as "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. This spatially relative relationship term is intended to include different orientations of the device in use or operation other than the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip, posture change or movement state change, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will subsequently be oriented as "above other elements or features" or "over other elements or features". Therefore, the exemplary term "below" can include both the upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0039] See Figures 1 to 6, an embodiment of the present application provides a test fixture, including: a fixture platform 100 having a fixing position for installing a radar module 10 to be tested, and the radar module 10 to be tested is provided with a first test terminal 11 and a second test terminal 12 that are electrically connected; a first clamping assembly 200 disposed near the fixing position on the fixture platform 100, the first clamping end of the first clamping assembly 200 clamps and is electrically connected to the first test terminal 11, and the first clamping end is electrically connected to the detection tooling 2; and a second clamping assembly 300 disposed on the fixture platform 100, the second clamping assembly 300 and the first clamping assembly 200 are arranged on opposite sides of the fixing position, the second clamping end of the second clamping assembly 300 clamps and is electrically connected to the second test terminal 12, and the second clamping end is electrically connected to the detection tooling 2.

[0040] In this embodiment, first, the radar module 10 to be tested is fixed at the fixing position on the fixture platform 100 to improve the position stability of the radar module 10 to be tested during the test process; then, the first test terminal 11 of the radar module 10 to be tested is clamped by the first clamping assembly 200, and the second test terminal 12 is clamped by the second clamping assembly 300 to improve the position stability and reliability of the first test terminal 11 and the second test terminal 12 during the test process; meanwhile, the first test terminal 11 is electrically connected to the first clamping end of the first clamping assembly 200, and the second test terminal 12 is electrically connected to the second clamping end of the second clamping assembly 300. In this way, an electrical circuit is formed between the radar module 10 to be tested and the detection tooling 2, and the detection tooling 2 can detect the performance of the first test terminal 11 and the second test terminal 12. Compared with the layout mode of directly connecting the FPC (flexible printed circuit) test terminal and the detection component through a wiring harness in the traditional test equipment, the test fixture 3 provided in this embodiment can not only realize the electrical connection between the two FPC test terminals and the detection tooling 2 through the first clamping end and the second clamping end respectively to detect the performance of the radar module 10 to be tested; but also clamp the two FPC test terminals of the radar module 10 to be tested on the first clamping assembly 200 and the second clamping assembly 300 respectively to improve the position stability of the two FPC test terminals and the accuracy and reliability of the test results. The structure of the entire test fixture 3 is simple, the layout is compact, the cost is low, which is conducive to miniaturization and industrial layout.

[0041] Specifically, the test fixture 3 is configured as a combined component including at least a fixture platform 100, a first clamping component 200, and a second clamping component 300. The fixture platform 100 can be a rectangular plate-like structure, and the fixing position thereon can be configured at the middle position to facilitate the fixing and performance testing of the radar module 10 to be tested. The fixing position can be a sunken square groove body, and a positioning post and a limiting sunk groove are provided at the bottom thereof. The radar module 10 to be tested can be an approximately square component, and a first test terminal 11 and a second test terminal 12 which are spaced apart and flexible are provided at the top thereof, and a positioning structure and a limiting post are provided at the bottom thereof. The radar module 10 to be tested is inserted into the fixing position, the positioning structure at the bottom thereof corresponds to the positioning post, and the limiting post at the bottom thereof is inserted into the limiting sunk groove, so as to improve the connection tightness and installation accuracy between the radar module 10 to be tested and the fixture platform 100, and improve the accuracy of the test result. The first test terminal 11 at the top of the radar module 10 to be tested can be a transmitting FPC test terminal, and the second test terminal 12 can be a receiving FPC test terminal. Both of them can be nearly long strip metal sheets with a certain flexibility and can be bent to a certain extent. Thus, by bending the first test terminal 11 and the second test terminal 12, they can be electrically connected and clamped to the first clamping end and the second clamping end respectively, so as to fix the upper and lower end positions of the radar module 10 to be tested, and improve the position stability and reliability of the radar module 10 to be tested during the test process. The first clamping component 200 and the second clamping component 300 are respectively arranged on the opposite sides of the fixing position to respectively clamp and fix the first test terminal 11 and the second test terminal 12.

[0042] It should be noted that both the first clamping component 200 and the second clamping component 300 include an open state and a clamping state, corresponding to the non-working state and the working state of the test fixture 3 respectively. When both the first clamping component 200 and the second clamping component 300 are in the clamping state, that is to say, the first clamping end clamps the first test terminal 11 and the second clamping end clamps the second test terminal 12. At this time, the test fixture 3 is in the working state, and the first clamping end emits a signal, which sequentially passes through the first clamping end, the detection tooling 2, and the second clamping end, and then is received by the second test terminal 12, so as to realize the performance testing of the radar module 10 to be tested such as noise points, current, distance, or electrical properties. When both the first clamping component 200 and the second clamping component 300 are in the open state, that is to say, the first test terminal 11 can be pulled out from the first clamping end and the second test terminal 12 can be pulled out from the second clamping end. At this time, the test fixture 3 is in the non-working state, and the tested radar module can be taken out from the test fixture 3.

[0043] In a possible implementation manner, the first clamping assembly 200 includes a first fixing bracket 210, a first clamping member 220, and a first electrical connection member 230. The first fixing bracket 210 is disposed on the jig platform 100. The first clamping member 220 and the first electrical connection member 230 are spaced apart and disposed on the side of the first fixing bracket 210 away from the jig platform 100. The first clamping member 220 is movably arranged. When the first test terminal 11 is electrically connected to the first electrical connection member 230, the first clamping member 220 clamps the first test terminal 11.

[0044] In this embodiment, the specific configuration of the first clamping assembly 200 is optimized. Specifically, the first clamping assembly 200 is configured as a combined component at least including the first fixing bracket 210, the first clamping member 220, and the first electrical connection member 230. The first fixing bracket 210 can be a wedge-shaped support with an inclined tabletop. The bottom of the support can be a platform structure similar to an inverted T shape, and it can be connected to the jig platform 100 through structures such as screws / bolts. The inclined tabletop at the top of the support faces the fixed position, so that the first test terminal 11 of the radar module 10 to be tested assembled at the fixed position is easily bent and aligned to the inclined tabletop, realizing the connection between the first test terminal 11 and the first fixing bracket 210. The first electrical connection member 230 can be a square block structure, on which a plurality of electrical connection holes are provided, and a conductive body is arranged in each electrical connection hole. When the first test terminal 11 is pressed onto the first electrical connection member 230, the conductive body can be conducted with the first test terminal 11, thereby realizing the electrical connection between the first electrical connection member 230 and the first test terminal 11. The first clamping member 220 can be a long plate-like structure, and its bottom end can be rotatably connected above the inclined tabletop through a torsion spring member. An abutting protrusion is arranged on the side of its top end facing the inclined tabletop. The abutting protrusion has a certain flexibility. For example, a soft rubber sleeve can be arranged outside the abutting protrusion, which can not only prevent the abutting protrusion from pressing and damaging the first test terminal 11 and the first electrical connection member 230, improving the mechanical protection of the first test terminal 11 and the first electrical connection member 230, but also realize the insulation protection of the first test terminal 11 and the first electrical connection member 230, improving the operation safety. When the first clamping member 220 abuts on the inclined tabletop, the abutting protrusion can press the first test terminal 11 electrically connected to the first electrical connection member 230, strengthening the connection tightness between the first test terminal 11 and the first electrical connection member 230 / the first fixing bracket 210, further improving the stable clamping of the first test terminal 11 of the radar module 10 to be tested by the first clamping assembly 200, and ensuring the reliability and accuracy of the test results.

[0045] It can be understood that the setting of the inclined table on the first fixing bracket 210 can, on the one hand, reduce the bending difficulty of the first test terminal 11, reduce the alignment and fixing difficulty between the first test terminal 11 and the first fixing bracket 210, and facilitate the operation of the operator; on the other hand, the slope of the inclined table can effectively reduce the length requirement for the first test terminal 11, improve the adaptability of the test fixture 3 to different models of radar modules 10 to be tested, and increase the applicable range of the test fixture 3. In addition, it can also improve the connection stability between the first test terminal 11 and the inclined table, and improve the reliability and accuracy of the detection results.

[0046] In a possible implementation manner, the second clamping assembly 300 includes a second fixing bracket 310, a second clamping member 320, and a second electrical connector 330. The second fixing bracket 310 is disposed on the fixture platform 100. The second clamping member 320 and the second electrical connector 330 are spaced apart and disposed on the side of the second fixing bracket 310 away from the fixture platform 100. The second clamping member 320 is movably arranged. When the second test terminal 12 is electrically connected to the second electrical connector 330, the second clamping member 320 clamps the second test terminal 12.

[0047] In this embodiment, the specific configuration of the second clamping assembly 300 is optimized. Specifically, the second clamping assembly 300 is configured as a combined component at least including a second fixing bracket 310, a second clamping member 320, and a second electrical connector 330. The second fixing bracket 310 can be a wedge-shaped support with an inclined tabletop. The bottom of the support can be a nearly inverted T-shaped platform structure, and it can be connected to the fixture platform 100 through structures such as screws / bolts. The inclined tabletop at the top of the support faces the fixed position, so that the second test terminal 12 of the radar module 10 to be tested assembled at the fixed position is easily bent and aligned to the inclined tabletop, realizing the connection between the second test terminal 12 and the second fixing bracket 310. The second electrical connector 330 can be a square block structure, with a plurality of electrical connection holes provided thereon. Each electrical connection hole is provided with a conductor, and the conductor can be conducted with the second test terminal 12 when the second test terminal 12 is pressed against the second electrical connector 330, thereby realizing the electrical connection between the second electrical connector 330 and the second test terminal 12. The second clamping member 320 can be a long plate-shaped structure. Its bottom end can be rotatably connected above the inclined tabletop through a torsion spring member. The top end thereof is provided with an abutting protrusion on the side facing the inclined tabletop. The abutting protrusion has a certain flexibility. For example, a soft rubber sleeve can be provided outside the abutting protrusion, which can not only prevent the abutting protrusion from pressing and damaging the second test terminal 12 and the second electrical connector 330, improving the mechanical protection of the second test terminal 12 and the second electrical connector 330, but also realize the insulation protection of the second test terminal 12 and the second electrical connector 330, improving the operation safety. The abutting protrusion can press the second test terminal 12 electrically connected to the second electrical connector 330 when the second clamping member 320 abuts on the inclined tabletop, strengthening the connection firmness between the second test terminal 12 and the second electrical connector 330 / the second fixing bracket 310, further improving the stable clamping of the second clamping assembly 300 on the second test terminal 12 of the radar module 10 to be tested, and ensuring the reliability and accuracy of the test results.

[0048] It can be understood that the setting of the inclined tabletop on the second fixing bracket 310 can, on the one hand, reduce the bending difficulty of the second test terminal 12, reduce the alignment and fixing difficulty between the second test terminal 12 and the second fixing bracket 310, and facilitate the operation of the operator; on the other hand, the slope of the inclined tabletop can effectively reduce the length requirement for the second test terminal 12, improve the adaptability of the test fixture 3 to different models of radar modules 10 to be tested, and increase the applicable range of the test fixture 3. In addition, it can also improve the connection stability between the second test terminal 12 and the inclined tabletop, and improve the reliability and accuracy of the detection results.

[0049] In a possible implementation manner, the first electrical connector 230 includes a first connection base 231, a first electrical connection portion 232, and a first telescopic portion 233. The first connection base 231 is connected to the first fixing frame 210 and is electrically connected to the detection tooling 2. The first electrical connection portion 232 is disposed on a side of the first connection base 231 away from the first fixing frame 210 and is electrically connected to the first connection base 231. The first telescopic portion 233 is telescopically disposed in the first connection base 231 and is located outside the first electrical connection portion 232.

[0050] In this embodiment, the specific configuration of the first electrical connector 230 is optimized. Specifically, the first electrical connector 230 is configured as a combined component including at least the first connection base 231, the first electrical connection portion 232, and the first telescopic portion 233. The first connection base 231 may be a rectangular block structure, and an installation sink is provided at its top. A connection position electrically connected to the detection tooling 2 is provided at the bottom of the installation sink. There are a plurality of connection positions, and the plurality of connection positions are arranged in a matrix. The first electrical connection portion 232 may be a structural member similar to a socket-and-plug, and it is inserted into the installation sink. A plurality of conductive pins arranged in a matrix are provided on the first electrical connection portion 232. The bottom of the conductive pins is electrically connected to the connection position, and the top of the conductive pins is used to electrically connect to the first test terminal 11. In this way, the electrical connection between the first test terminal 11 and the first electrical connector 230 is achieved. The first telescopic portion 233 may be a C-shaped block structure, an L-shaped block member, or a U-shaped block member. It is inserted into the installation sink and semi-circularly surrounds the periphery of the first electrical connection portion 232 for insulating protection of the first electrical connection portion 232. Specifically, when the first clamping member 220 is not in contact with the first electrical connector 230, the first telescopic portion 233 protrudes from the first electrical connection portion 232. At this time, the first telescopic portion 233 can not only achieve insulating protection for the first electrical connection portion 232 and the first test terminal 11, but also achieve limiting and guiding for the first test terminal 11, facilitating the electrical connection between the first test terminal 11 and the first electrical connection portion 232.
