[0002] OTA (Over-The-Air) is a technology that uses mobile communication networks to remotely upgrade automotive software. It enables the iteration of vehicle system functions, fault repair, and performance optimization. It is one of the core technologies of intelligent connected vehicles. OTA involves the entire process from software development, packaging, transmission to installation, and requires rigorous testing at different stages to ensure the safety, stability, and compatibility of the upgrade.

[0003] In the existing technology, the OTA device needs to be tested during the production and processing of the device. However, the test bench is difficult to stably adapt to OTA devices of different sizes and specifications, which will affect the stability of the test process. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the test bench is difficult to stably adapt to OTA devices of different sizes and specifications during the production and processing of OTA devices, which affects the stability of the test process. Therefore, this invention proposes a test bench for automated testing of OTA devices for connected vehicles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A test bench for OTA automated testing of connected vehicles includes a test bench, a support plate fixedly connected to the side wall of the test bench, a controller provided on the top side wall of the support plate, a groove formed on the inner wall of the top of the test bench, a bidirectional lead screw rotatably connected to the inner wall of the groove, a motor fixedly connected to the side wall of the test bench, the output shaft of the motor fixedly connected to the end of the bidirectional lead screw, two sliders threadedly connected to the wall of the bidirectional lead screw, clamps fixedly connected to the top ends of the two sliders respectively, and a wire electrically connected to the side wall of the controller, with a terminal electrically connected to the end of the wire away from the controller.

[0007] Preferably, an anti-slip pad is fixedly connected to the side wall of the clamping block.

[0008] Preferably, the conductor is configured as a helical conduit.

[0009] Preferably, a fixing plate is fixedly connected to the top of the clamping block, an opening is provided on the inner wall of the top of the fixing plate, a lever is fixedly connected to the side wall of the connector, and the connector is placed on the inner wall of the opening.

[0010] Preferably, a metal bracket is fixedly connected to the bottom of the connector, and a slot is provided on the inner wall of the opening of the fixing plate, with the metal bracket clamped to the inner wall of the slot.

[0011] Preferably, a magnetic block is fixedly connected to the inner wall of the card slot on the fixing plate, and the magnetic block is adsorbed onto the metal card holder.

[0012] Compared with the prior art, this utility model provides a test bench for automated OTA testing of connected vehicles, which has the following advantages:

[0013] 1. This test bench for OTA automated testing of connected vehicles uses a bidirectional lead screw with opposite thread directions at both ends to move two sliders along the inner wall of the groove towards or away from each other, synchronously adjusting the spacing between the clamping blocks. When testing vehicle modules of different sizes, the motor can automatically adjust the position of the clamping blocks according to a preset program to adapt to equipment with different widths. The anti-slip pads on the inner side of the clamping blocks are made of silicone rubber, which increases the friction of the contact surface to fix the equipment. When the sliders move to the clamping position, the anti-slip pads fit tightly against the equipment shell, and together with the self-locking characteristics of the lead screw, prevent the equipment from shifting during the test.

[0014] 2. The test bench for OTA automated testing of connected vehicles uses a spiral tube structure for the wires, which can freely extend and retract with the movement of the clamps, avoiding wire breakage due to frequent pulling. The spiral tube contains multi-strand twisted shielded wires, which can resist electromagnetic interference and ensure the stability of data transmission during OTA testing.

[0015] 3. This test bench for OTA automated testing of connected vehicles uses a connector to engage with the slot of the fixed plate via a metal bracket, ensuring reliable contact. A magnetic block attracts the metal bracket to prevent the connector from loosening due to vibration. During testing, a lever is used to manually adjust the angle of the connector. After aligning it with the equipment interface, press it down, and the bracket will automatically snap into the slot to complete the connection. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A test bench for OTA automated testing of connected vehicles includes a test bench 1. A support plate 2 is fixedly connected to the side wall of the test bench 1. A controller 3 is provided on the top side wall of the support plate 2. A groove is opened on the inner wall of the top of the test bench 1. A bidirectional lead screw 4 is rotatably connected to the inner wall of the groove. A motor 5 is fixedly connected to the side wall of the test bench 1. The output shaft of the motor 5 is fixedly connected to the end of the bidirectional lead screw 4. Two sliders 6 are threadedly connected to the rod wall of the bidirectional lead screw 4. Clamping blocks 7 are fixedly connected to the top of the two sliders 6 respectively. A wire 9 is electrically connected to the side wall of the controller 3. A terminal 10 is electrically connected to the end of the wire 9 away from the controller 3.

[0022] Anti-slip pads 8 are fixedly connected to the side wall of clamp 7, and wires 9 are set as spiral conduits.

[0023] After the motor 5 starts, it drives the bidirectional lead screw 4 to rotate. The threads at both ends of the lead screw turn in opposite directions, causing the two sliders 6 to move towards or away from each other along the inner wall of the groove. The spacing of the clamping blocks 7 is adjusted synchronously. When testing vehicle modules of different sizes, the motor 5 can automatically adjust the position of the clamping blocks 7 according to the preset program to adapt to equipment with different width ranges. The anti-slip pad 8 on the inner side of the clamping block 7 is made of silicone rubber. It fixes the equipment by increasing the friction of the contact surface. When the slider 6 moves to the clamping position, the anti-slip pad 8 fits tightly against the equipment shell. Combined with the self-locking characteristics of the lead screw, it prevents the equipment from shifting during the test.

[0024] The conductor 9 adopts a spiral tube structure, which can freely extend and retract with the movement of the clamp 7, avoiding the conductor from breaking due to frequent pulling. The inside of the spiral tube is a multi-strand twisted shielded wire, which can resist electromagnetic interference and ensure the stability of data transmission during OTA testing.

[0025] To prevent connector 10 from loosening due to vibration, such as Figure 1-3 As shown, a fixing plate 11 is fixedly connected to the top of the clamping block 7. An opening is provided on the inner wall of the top of the fixing plate 11. A lever 12 is fixedly connected to the side wall of the connector 10. The connector 10 is placed on the inner wall of the opening. A metal card holder 13 is fixedly connected to the bottom of the connector 10. A card slot is provided on the inner wall of the opening of the fixing plate 11. The metal card holder 13 is clamped and set on the inner wall of the card slot. A magnetic block 14 is fixedly connected to the inner wall of the card slot of the fixing plate 11. The magnetic block 14 is attracted to the metal card holder 13.

[0026] The connector 10 is engaged with the slot of the fixing plate 11 via the metal bracket 13 to ensure reliable contact. The magnetic block 14 attracts the metal bracket 13 to prevent the connector 10 from loosening due to vibration. During testing, the lever 12 is used to manually adjust the angle of the connector 10. After aligning it with the equipment interface, it is pressed down, and the bracket automatically snaps into the slot to complete the connection.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
