Description

Technical Field

[0001] This utility model relates to the field of interface testing technology, and in particular to a rapid positioning vehicle flow test module and an automated testing device. Background Technology

[0002] A domain controller is a new type of automotive electronic controller that divides the functions of various automotive electronics into several domains, such as the powertrain domain, body electronics domain, and driver assistance domain. It then utilizes the powerful processing capabilities of multi-core CPUs / GPUs within these relatively centralized control domains to address most of the functions originally belonging to individual ECUs, thus meeting the growing needs of vehicle electronics. Domain controllers enable vehicles to perform multi-sensor fusion, localization, path planning, and decision-making control. Functions typically requiring external connection of multiple cameras, millimeter-wave radars, lidar, etc., include image recognition and data processing.

[0003] Because the types and number of interfaces of domain controllers in different vehicles vary, the existing test modules have weak compatibility and cannot meet the testing requirements of different domain controllers at the same time. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rapid positioning vehicle flow test module and an automated test device, which has good compatibility and can simultaneously meet the testing needs of different types of domain controllers.

At the same time, a first guide part is formed at one end of the connecting unit and a second guide part is formed at one end of the adapter unit. One of the first guide part and the second guide part is constructed as a first guide groove, and the other is constructed as a first guide protrusion. The cooperation of the first guide protrusion and the second guide groove is used for guidance, ensuring that the multiple connecting units and multiple adapter units can be connected smoothly one by one, reducing the risk of damage to the connecting units and adapter units.

[0008] In one embodiment of this implementation, one of the fixed seat and the movable seat is provided with a second guide protrusion, and the other is provided with a second guide groove. The second guide groove includes two first sidewalls arranged opposite to each other.

[0011] In one embodiment of this implementation, the bottom wall of the limiting groove is provided with a protrusion, which can abut against the top surface of the limiting protrusion facing away from the second side wall, and the distance between the protrusion and the limiting protrusion is greater than the distance between the second guide protrusion and the opening of the second guide groove.

[0012] In one embodiment of this implementation, the limiting protrusion is provided with a first inclined surface connected to the top surface, and the protrusion can slide along the first inclined surface to abut against the top surface.

[0013] In one embodiment of this implementation, the bump is provided with a second inclined surface that matches the first inclined surface.

[0014] In one embodiment of this implementation, the end of the second guide protrusion is provided with a first conical surface, and the sidewall at the opening of the second guide groove is constructed as a second conical surface.

[0035] Please see Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of a rapid positioning vehicle flow test module 100 according to one embodiment of the present invention; Figure 2 yes Figure 1 A schematic diagram of the structure of the fixed module 10 in the rapid positioning vehicle flow test module 100; Figure 3 yes Figure 1 A schematic diagram of the structure of the moving module 20 in the rapid positioning carrier flow test module 100. This utility model provides a rapid positioning carrier flow test module 100, which includes a fixed module 10 and multiple moving modules 20, each used for electrical connection with different types of test products. The fixed module 10 includes a fixed base 11 and multiple connecting units 12 mounted on the fixed base 11. One end of each connecting unit 12 has a first guide portion 121, and the other end is used for electrical connection with a test instrument. The moving module 20 includes a moving base 21 and multiple adapter units 22 mounted on the moving base 21. One end of each adapter unit 22 has a second guide portion 221, and the other end is used for electrical connection with the test product. One of the first guide portion 121 and the second guide portion 221 is constructed as a first guide groove, and the other is constructed as a first guide protrusion. The movable seat 21 is used to be mounted on the carrier and driven by the carrier to approach the fixed seat 11, so that the first guide protrusion extends into the first guide groove to cooperate, and the connecting unit 12 is connected to the transfer unit 22.

[0036] Specifically, the connection unit 12 has a connection terminal, one end of which is connected to the testing instrument via a cable to receive the test signal from the testing instrument, and the other end of the connection terminal is a female terminal. The adapter unit 22 has an adapter terminal, one end of which is connected to the test adapter via a cable. The test adapter is electrically connected to the test product, and the other end of the adapter terminal is a male terminal that can be plugged into the female terminal to realize the transmission of the test signal, so that the test product receives the test signal and meets the test requirements of the test product.

[0037] Specifically, the mounting base 11 includes a first top plate 115, a first bottom plate 116 and two first side plates 117. The first top plate 115 and the first bottom plate 116 are arranged opposite to each other and are connected to the two first side plates 117 to define a first installation area. Multiple connecting units 12 are installed in the first installation area.

[0038] Specifically, the movable seat 21 includes a second top plate 215, a second bottom plate 216 and two second side plates 217. The second top plate 215 and the second bottom plate 216 are arranged opposite to each other and are connected to the two second side plates 217 to define a second installation area. Multiple adapter units 22 are installed in the second installation area.

[0039] In this embodiment, the first guide portion 121 is configured as a first guide protrusion, and the second guide portion 221 is configured as a first guide groove. In other embodiments, the first guide portion 121 may also be configured as a first guide groove, and the second guide portion 221 may be configured as a first guide protrusion.

[0040] It is understood that in this embodiment, the number of connecting units 12 on the fixed base 11 is eight, and the number of adapter units 22 on the movable base 21 is eight, with each of the eight connecting units 12 and the eight adapter units 22 corresponding to one another. All eight connecting units 12 on the fixed base 11 are electrically connected to the testing instrument, while the eight adapter units 22 on the movable base 21 are selectively electrically connected to the testing product according to the test product that the current movable module 20 needs to test. For example, if the eight adapter units 22 are defined to correspond to product interfaces A, B, C, D, E, F, G, and H respectively, and the current test product needs to test interfaces A, B, C, and D, then the test product only needs to be electrically connected to the corresponding four adapter units 22 to complete the test. For other movable modules 20, if the required test interfaces are C, D, E, F, G, and H, then the test product only needs to be electrically connected to the corresponding six adapter units 22 to complete the test.

[0041] Understandably, due to the need for testing to be compatible with multiple products, the number of connecting units 12 on the fixed base 11 and the number of adapter units 22 on the movable base 21 are relatively large, and the shapes of different connecting units 12 and different adapter units 22 are different, which can easily lead to damage due to misalignment.

[0042] By setting up a fixed module 10 and multiple moving modules 20, the connecting unit 12 in the fixed module 10 is electrically connected to the testing instrument, and the transfer units 22 in the multiple moving modules 20 are electrically connected to different types of testing products, so that different types of testing products can be tested by the same testing instrument, thereby improving compatibility and meeting the testing needs of different testing products at the same time. At the same time, a first guide part 121 is formed at one end of the connecting unit 12, and a second guide part 221 is formed at one end of the transfer unit 22. One of the first guide part 121 and the second guide part 221 is constructed as a first guide groove, and the other is constructed as a first guide protrusion. The cooperation of the first guide protrusion and the second guide groove 211 is used for guidance, ensuring that the multiple connecting units 12 and the multiple transfer units 22 can be connected smoothly one by one, reducing the risk of damage to the connecting units 12 and the transfer units 22.

[0043] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 One of the fixed base 11 and the movable base 21 is provided with a second guide protrusion 111, and the other is provided with a second guide groove 211. The second guide groove 211 includes two opposing first sidewalls 2111. When the carrier moves the movable base 21 closer to the fixed base 11, the second guide protrusion 111 extends into the second guide groove 211 and abuts against the two first sidewalls 2111. Specifically, the two first sidewalls 2111 are arranged opposite each other in the vertical direction. With this arrangement, the second guide protrusion 111 can abut against the two first sidewalls 2111 of the second guide groove 211, thereby completing the vertical positioning of the fixed base 11 and the movable base 21, so that the multiple connecting units 12 and the multiple adapter units 22 can be aligned and connected one by one.

[0044] In this embodiment, the second guide protrusion 111 is disposed on the fixed base 11, and the second guide groove 211 is formed in the movable base 21. In other embodiments, the second guide protrusion 111 may also be disposed on the movable base 21, and the second guide groove 211 may be formed in the fixed base 11.

[0045] In this embodiment, there are two second guide protrusions 111, which are respectively disposed on the two first side plates 117. There are also two second guide grooves 211, which are respectively disposed on the two second side plates 217.

[0046] In one embodiment of this implementation, please refer to Figure 1The distance between the second guide protrusion 111 and the opening of the second guide groove 211 is less than the distance between the first guide protrusion and the opening of the first guide groove. With this configuration, during testing, positioning can be achieved first through the second guide protrusion 111 and the second guide groove 211, and then guided by the second guide protrusion 111 and the second guide groove 211, allowing multiple connecting units 12 and multiple transition units 22 to be aligned and connected.

[0047] In one embodiment of this implementation, please refer to Figures 2 to 5 , Figure 4 yes Figure 2 A schematic diagram of the structure of a portion of the fixing seat 11 in the fixing module 10; Figure 5 yes Figure 3 This is a schematic diagram of the structure of a portion of the movable seat 21 in the movable module 20. The second guide protrusion 111 has a limiting groove 1111. The second guide groove 211 includes a second sidewall 2112 connecting the two first sidewalls 2111. The second sidewall 2112 forms a limiting protrusion 2113. When the second guide protrusion 111 extends into the second guide groove 211, the limiting protrusion 2113 abuts against the bottom wall of the limiting groove 1111. Specifically, there are two second sidewalls 2112, which are arranged opposite each other in the left-right direction. This arrangement allows the fixed seat 11 and the movable seat 21 to be positioned in the left-right direction by the abutment between the limiting protrusion 2113 and the bottom wall of the limiting groove 1111, ensuring that multiple connecting units 12 and multiple transition units 22 can be aligned one by one.

[0048] In this embodiment, one of the second sidewalls 2112 forms a limiting protrusion 2113, which abuts against the bottom wall of the limiting groove 1111, and the other second sidewall 2112 abuts against the surface of the second guide protrusion 111, thereby completing the positioning in the left and right directions.

[0049] In one embodiment of this implementation, please refer to Figures 2 to 5 The bottom wall of the limiting groove 1111 is provided with a protrusion 1112. The protrusion 1112 can abut against the top surface 2115 of the limiting protrusion 2113 facing away from the second side wall 2112. The distance between the protrusion 1112 and the limiting protrusion 2113 is greater than the distance between the second guide protrusion 111 and the opening of the second guide groove 211. With this configuration, during the process of the second guide protrusion 111 extending into the second guide groove 211, the vertical positioning can be completed first by the abutment of the second guide protrusion 111 against the two first side walls 2111, and then the horizontal positioning can be completed by the abutment of the protrusion 1112 against the top surface 2115 of the limiting protrusion 2113. Thus, the positioning in both directions is completed sequentially, reducing the risk of hard collision due to misalignment between the second guide protrusion 111 and the second guide groove 211, and improving reliability.

[0050] In one embodiment of this implementation, please refer to Figures 2 to 5 The limiting protrusion 2113 has a first inclined surface 2114 that connects to the top surface 2115, and the protrusion 1112 can slide along the first inclined surface 2114 to abut against the top surface 2115. This configuration ensures that the protrusion 1112 can be positioned left and right with the limiting protrusion 2113, thus improving the fault tolerance rate.

[0051] In one embodiment of this implementation, please refer to Figures 2 to 5 The protrusion 1112 is provided with a second inclined surface 1113 that matches the first inclined surface 2114. This configuration can further improve the fault tolerance of left and right positioning.

[0052] In one embodiment of this implementation, please refer to Figures 2 to 5 The end of the second guide protrusion 111 is provided with a first conical surface 1114, and the side wall at the opening of the second guide groove 211 is constructed as a second conical surface 2116. The second conical surface 2116 can abut against the first conical surface 1114, so that the second guide protrusion 111 can extend into the second guide groove 211 along the second conical surface 2116. This arrangement ensures that the second guide protrusion 111 can smoothly extend into the second guide groove 211, improving the fault tolerance of guidance and the fault tolerance of vertical positioning.

[0053] In one embodiment of this implementation, please refer to Figures 2 to 5 The first guide protrusion has a third conical surface 1211 at its end, and the sidewall at the opening of the first guide groove is constructed as a fourth conical surface 2211. The third conical surface 1211 can abut against the fourth conical surface 2211, allowing the first guide protrusion to extend into the first guide groove along the fourth conical surface 2211. This arrangement ensures that the first guide protrusion can smoothly extend into the first guide groove, enabling the connection terminal and the adapter terminal to be connected.

[0054] Please see Figure 1 This invention provides an automated testing device, which includes multiple carriers (not shown), a motion mechanism, and a rapid positioning carrier flow testing module 100. Multiple movable seats 21 are respectively mounted on corresponding carriers. The motion mechanism is connected to the multiple carriers and can drive the multiple carriers to connect the transfer units 22 on the corresponding movable seats 21 with the connection units 12 on the fixed base 11. By incorporating the rapid positioning carrier flow testing module 100 provided in this invention into the automated testing device, the device can simultaneously meet the automated testing needs of different types of products, improving testing efficiency.

[0055] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
