Description

Technical Field

[0001] The present invention belongs to the technical field of automotive interior and exterior trim parts, and particularly relates to an anti-misassembly tooling for an automotive radar bracket. Background Art

[0002] An automotive radar is a radar used for automobiles or other ground motor vehicles, which includes various different radars based on different technologies (such as laser, ultrasonic, microwave) and has different functions (such as detecting obstacles, predicting collisions, adaptive cruise control). It can undertake some tasks that require attention, judgment, and technical skills, thereby reducing the driving intensity and the burden on the driver.

[0003] A radar bracket is a connecting device that connects an automotive rearview radar to an automotive bumper. The radar bracket needs to be welded to the bumper on a welding device first, and finally, the radar is installed on the general assembly line. To achieve a better parking effect, generally 6 - 12 radar sensors need to be arranged on each of the front and rear bumpers, so 6 - 12 radar brackets are required. Since the radars have the same appearance, the radar brackets look similar, and it is very easy to misassemble the radar brackets on the welding device, which not only wastes time but also causes unnecessary economic losses. Therefore, there is an urgent need to develop an effective anti-misassembly device for radar brackets. Summary of the Invention

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide an anti-misassembly tooling for an automotive radar bracket, which is used to solve the problem that the radar bracket is easily misassembled during welding in the prior art.

[0005] To achieve the above purpose and other related purposes, the present invention provides an anti-misassembly tooling for an automotive radar bracket, which includes an anti-misassembly mechanism and a power source connected in series in a circuit. The anti-misassembly mechanism includes a welding base and a limiting boss and a touch component arranged on the welding base. Conductive components are symmetrically arranged at both ends of the touch component, and each conductive component is connected to a wire connected to the power source. The limiting boss is used to install the radar bracket. When the radar bracket is correctly assembled, the radar bracket presses on the touch component, so that the touch component is simultaneously connected to the conductive components at both ends to conduct the circuit; when the radar bracket is misassembled, the radar bracket does not contact the touch component.

[0006] Further, the touch component includes a touch pillar and a pillar seat arranged on the welding base. The touch pillar is arranged in the pillar seat and can reciprocate vertically, and a pillar hole penetrating radially is arranged at the bottom of the touch pillar, and a main copper sheet is inserted into the pillar hole.

[0007] Further, a main spring is sleeved on the touch pillar. The top of the touch pillar has a pillar disc head, and the main spring is arranged between the pillar disc head and the pillar seat.

[0008] Further, one end of the top of the radar bracket has a bracket boss. When the radar bracket is correctly assembled, the bracket boss is aligned with the touch pillar.

[0009] Further, the conduction component includes a guide post and a limit disc head arranged on the welding base. The guide post is arranged in the limit disc head and can reciprocate vertically. And the top end of the guide post has a guide post platform. A copper shunt is connected to the guide post platform through a first bolt. Insulating bushings are sleeved on both ends of the copper shunt, and the top surface of the copper shunt is aligned with one end of the main copper sheet.

[0010] Further, a sub-spring is sleeved on the guide post, and the sub-spring is arranged between the guide post platform and the limit disc head.

[0011] Further, a housing is sleeved outside the touch component and the conduction component. A housing hole is opened at the top of the housing, and the touch pillar can reciprocate vertically in the housing hole.

[0012] Further, both ends of the housing have through wire holes. The wire passes through the wire holes and is connected to the conduction component. The housing is connected to the welding base through a second bolt.

[0013] Further, a stop step is arranged at the top of the limit boss, and the stop step defines the displacement of the downward movement of the radar bracket.

[0014] Further, locking buckles are symmetrically arranged on the outer wall of the limit boss. There are buckle holes on the radar bracket. When the radar bracket moves downward in place, the buckle holes are clamped on the locking buckles.

[0015] As described above, the anti-misassembly tooling for an automotive radar bracket of the present invention has the following beneficial effects:

[0016] By designing the anti-misassembly tooling for the automotive radar bracket in the welding circuit of the radar bracket, when correctly assembled, the radar bracket will press against the touch component, so that the touch component is connected to the conduction component to conduct the circuit for welding work. On the contrary, when misassembled, an open circuit will be formed and the welding work cannot be achieved. The present invention can effectively prevent the mixed assembly and misassembly of products, thereby avoiding unnecessary economic losses. Moreover, the development cost is low, the structure is stable, it is durable, the operation of workers is simple, and it can be applied to various types of radar brackets.

[0035] Figure 1 It is a layout schematic diagram of the anti - error tooling for the automotive radar bracket of the present invention. Figure 2 It is a schematic diagram of the anti - error mechanism. Figure 3 It is an axonometric view of the anti - error mechanism. Figure 1 , Figure 4 It is an axonometric view of the anti - error mechanism (excluding the housing). Figure 2 , please refer to Figures 1 to 4As shown in the figure, the present invention provides an anti-misassembly tooling for an automotive radar bracket, which includes an anti-misassembly mechanism 100 and a power supply 200 connected in series in a circuit. The anti-misassembly mechanism 100 includes a welding base 10, a limiting boss 11 and a touch component arranged on the welding base 10. Conducting components are symmetrically arranged at both ends of the touch component, and each conducting component is connected to a wire 400 connected to the power supply 200. The limiting boss 11 is used for installing the radar bracket 50. When the radar bracket 50 is correctly assembled, the radar bracket 50 moves downward along the limiting boss 11 and presses on the touch component, so that the touch component is simultaneously connected to the conducting components at both ends, and the circuit is in a conducting state; when the radar bracket 50 is incorrectly assembled, the radar bracket 50 does not contact the touch component, and the circuit is in an open state.

[0036] Specifically, a switch 300 is also connected in series in the circuit formed by the anti-misassembly mechanism 100 and the power supply 200. When the radar bracket 50 is correctly assembled, the radar bracket 50 can press on the touch component during installation, so that the touch component is connected to the conducting component to conduct the circuit. At this time, if the switch 300 is turned on, the welding work on the radar bracket 50 can be carried out normally; when the radar bracket 50 is incorrectly assembled, the radar bracket 50 does not contact the touch component during downward installation, so that the circuit cannot be conducted. If the switch 300 is turned on, the work cannot be carried out, thus effectively preventing the mixed assembly and misassembly of the radar bracket 50 and avoiding unnecessary economic losses.

[0037] Among them, referring to Figure 5 、 Figure 6 and Figure 8 ,the touch component includes a touch pillar 21 and a pillar seat 22 arranged on the welding base 10. The touch pillar 21 is arranged in the pillar seat 22 and can move vertically back and forth, and a pillar hole 212 penetrating radially is arranged at the bottom of the touch pillar 21. A main copper sheet 23 is inserted into the pillar hole 212. Specifically, the pillar seat 22 is cylindrical, and the pillar seat 22 is arranged in a pillar seat mounting hole 12 on the welding base 10 (see Figure 14) The pillar seat mounting hole 12 is a blind hole, which plays a role in supporting the pillar seat 22 and providing planar limit. A through pillar mounting hole 221 is provided inside the pillar seat 22, and the touch pillar 21 is arranged in the pillar mounting hole 221, enabling the touch pillar 21 to reciprocate vertically in the pillar mounting hole 221. The main copper sheet 23 is inserted into the pillar hole 212, and the pillar hole 212 is in interference fit with the main copper sheet 23 to ensure that the main copper sheet 23 can be firmly installed with the touch pillar 21 and move together with the touch pillar 21. A copper sheet stop hole 222 penetrating radially is provided on the side wall of the pillar seat 22, and both ends of the main copper sheet 23 are located in the copper sheet stop hole 222 after extending out of the pillar hole 212.

[0038] Moreover, a main spring 24 is sleeved on the touch pillar 21. The top of the touch pillar 21 has a pillar disc head 211, and the main spring 24 is arranged between the pillar disc head 211 and the pillar seat 22. Specifically, both ends of the main spring 24 are respectively defined by the pillar disc head 211 and the pillar seat 22, and the fitting clearance between the pillar mounting hole 221 at the top of the pillar seat 22 and the touch pillar 21 is small (it can be 0.1 mm). The bottom end of the main spring 24 is defined by the top end of the pillar seat 22 to prevent it from falling off. And the main spring 24 can play a role in supporting and resetting the touch pillar 21. When the touch pillar 21 is vertically moved downward under the action of the force F of the radar bracket 50, the main spring 24 is compressed. When the pressure on the touch pillar 21 is removed, the main spring 24 rebounds, causing the touch pillar 21 and the main copper sheet 23 to move vertically upward together. At the same time, the displacement of the main copper sheet 23 is limited by the copper sheet stop hole 222, enabling the touch pillar 21 and the main copper sheet 23 to be reset.

[0039] Refer to Figure 4 and Figure 7 , the conduction component includes a guide post 31 and a limit disc head 32 arranged on the welding base 10. The guide post 31 is arranged in the limit disc head 32 and can reciprocate vertically. Specifically, a limit disc head mounting hole 13 (see Figure 14 ) is provided on the welding base 10. The limit disc head mounting hole 13 is a blind hole, and a guide post mounting hole 14 is provided at the center of the limit disc head mounting hole 13. The guide post mounting hole 14 is a through hole. A disc head hole is provided at the center of the limit disc head 32, and a disc head groove penetrating the disc head hole radially is further provided on the limit disc head 32. A clamping platform is provided at the bottom end of the guide post 31. The clamping platform of the guide post 31 passes through the disc head hole and the disc head groove of the limit disc head 32, and the displacement of the guide post 31 is limited by the clamping platform.

[0040] The top end of the guide post 31 has a guide post platform 311, and a copper shunt 33 is arranged on the guide post platform 311. The copper shunt 33 is U-shaped, and the copper shunt 33 is connected to the guide post platform 311 by two first bolts 34. A wire 400 can be connected between the first bolt 34 and the copper shunt 33. The top surface of the copper shunt 33 aligns with one end of the main copper sheet 23, so that both ends of the main copper sheet 23 can be in contact with or separated from the two copper shunts 33 simultaneously. In the free state, the main copper sheet 23 and the two copper shunts 33 are in a separated state, and the circuit is in an open state; when the touch pillar 21 is pressed and moves downward, both ends of the main copper sheet 23 are pressed against the two copper shunts 33 simultaneously, thereby conducting the circuit.

[0041] Insulating guide sleeves 35 are sleeved on both ends of the copper shunt 33, and insulating guide sleeve mounting holes 15 (see Figure 14 ) are arranged on the welding base 10. The insulating guide sleeve mounting holes 15 are through holes. The insulating guide sleeves 35 are arranged in the insulating guide sleeve mounting holes 15 and are in interference fit with the insulating guide sleeve mounting holes 15, so that the insulating guide sleeves 35 are firmly installed. The copper shunt 33 is in interference fit with the insulating guide sleeves 35, so that both ends of the copper shunt 33 are fixed firmly.

[0042] Moreover, a sub-spring 36 is sleeved on the guide post 31, and the sub-spring 36 is arranged between the guide post platform 311 and the limit disc head 32. Specifically, both ends of the sub-spring 36 are defined by the guide post platform 311 and the limit disc head 32. The sub-spring 36 can play a supporting role and a resetting role for the guide post 31. When the touch pillar 21 moves vertically downward under the action of the radar bracket 50, the main copper sheet 23 presses the two copper shunts 33 at both ends, and the sub-spring 36 is compressed. After the pressure on the touch pillar 21 is removed, the touch pillar 21 and the main copper sheet 23 move vertically upward together, and the sub-spring 36 rebounds to reset the guide post 31 and the copper shunt 33.

[0043] In addition, referring to Figure 3 、 Figure 9 and Figure 10 , a housing 40 is sleeved outside the touch assembly and the conduction assembly. A housing hole 41 is opened at the top of the housing 40, and the touch pillar 21 can reciprocate vertically in the housing hole 41. The clearance between the housing hole 41 and the touch pillar 21 is small (it can be 0.1 mm) to ensure that the touch pillar 21 reciprocates vertically without falling off.

[0044] Both ends of the housing 40 are provided with through wire holes 42. The wire 400 passes through the wire holes 42 and is connected to the conduction component. The housing 40 is connected to the welding base 10 by the second bolts 44. Specifically, for each conduction component, by loosening the first bolt 34, the wire 400 can be arranged between the first bolt 34 and the copper shunt 33, and then the first bolt 34 is tightened to fix the wire. Bolt mounting holes 43 are provided at the four corners of the housing 40. Correspondingly, referring to Figure 14 , four bolt positioning holes 16 are provided on the welding base 10. The housing 40 is connected and fixed to the welding base 10 by passing four second bolts 44 through the bolt mounting holes 43 and the bolt positioning holes 16.

[0045] Referring to Figures 11 to 13 , the limiting boss 11 is arranged on the welding base 10, and the limiting boss 11 is cylindrical. A stop step 111 is provided at the top of the limiting boss 11. The stop step 111 defines the displacement of the radar bracket 50 moving downward. The stop step 111 is arranged in a circle around the circumferential direction of the limiting boss 11. Since a plurality of limiting ribs 53 are provided on the inner wall of the top of the radar bracket 50, the limiting ribs 53 ensure that the radar bracket 50 will not loosen when assembled to the base, and the stop step 111 can define the limiting ribs 53, thereby defining the displacement of the radar bracket 50 when moving downward. (When the radar bracket 50 moves downward, it first presses the touch pillar 21, so that the main copper sheet 23 on the touch pillar 21 is pressed against the copper shunts 33 at both ends. When the radar bracket 50 continues to move downward until the stop step 111 touches the limiting ribs 53 to limit the continuous movement of the radar bracket 50)

[0046] The limiting boss 11 simulates the assembly of the radar. Locking buckles 112 are symmetrically arranged on the outer wall of the limiting boss 11. The radar bracket 50 has buckle holes 52. When the radar bracket 50 moves downward in place, the buckle holes 52 are clamped on the locking buckles 112. In this way, it can be ensured that the radar bracket 50 will not rebound or move around after moving downward in place. In this embodiment, the clamping angle of the locking buckle 112 is 40°, which is convenient for the subsequent disassembly of the radar bracket 50.

[0047] In order to be able to distinguish whether the radar bracket 50 is correctly assembled, one end of the top of the radar bracket 50 has a bracket boss 51. When the radar bracket 50 is correctly assembled, the bracket boss 51 is located above the touch pillar 21, and the bracket boss 51 is aligned with the touch pillar 21. In this way, during the downward pressing process of the radar bracket 50, the bracket boss 51 can press the touch pillar 21, causing the touch pillar 21 to move downward, so that the main copper sheet 23 presses the sub-copper sheet 33, making the circuit conductive; conversely, if the assembly is incorrect, the touch pillar 21 cannot be pressed. For radar brackets 50 at different positions, the position of the bracket boss 51 can be changed, and at the same time, the position of the anti-misassembly mechanism 100 is correspondingly changed. In this way, if the radar bracket 50 is misassembled, it cannot contact the touch pillar 21 to connect the power supply 200.

[0048] When specifically used, first, the radar bracket 50 is assembled on the limit boss 11 for welding preparation. During the downward assembly process of the radar bracket 50, when the distance between the bottom end of the radar bracket 50 and the locking buckle 112 on the limit boss 11 is 5 mm, the bracket boss 51 of the radar bracket 50 starts to contact the touch pillar 21. Continuing to install downward, the main spring 24 (set stroke 5 mm) is compressed. When the main spring 24 is compressed by 4 mm, the main copper sheet 23 contacts the sub-copper sheets 33 at both ends simultaneously (in this embodiment, the thickness of the sub-copper sheet 33 is 0.7 mm for easy deformation). Continuing to compress by 1 mm, the sub-copper sheet 33 compresses the sub-spring 36 through the guide post 31. Here, it is set to continue pressing down by 1 mm to ensure that the main copper sheet 23 is in close contact with the sub-copper sheets 33 at both ends. Even after multiple contacts, they can be closely attached together and move downward together (the downward stroke together can be adjusted) until the radar bracket 50 is locked by the two locking buckles 112 on the limit boss 11, stopping the movement of the entire anti-misassembly mechanism 100. At this time, both the main spring 24 and the sub-spring 36 are in a compressed state, the main copper sheet 23 is in close contact with the sub-copper sheet 33, and the circuit is conductive. After that, the entire device is installed in the bumper, the switch 300 is turned on, and welding starts. After the welding is completed, the welding equipment removes the bumper (the radar bracket 50 is welded to the bumper and falls off with the bumper. Here, the removal force is greater than the clamping force of the radar bracket 50 on the limit boss 11). Since the radar bracket 50 is removed, the entire anti-misassembly mechanism 100 removes the downward pressure, the main spring 24 and the sub-spring 36 rebound, the main copper sheet 23 and the sub-copper sheet 33 are separated, forming an open circuit, and it can enter the next welding preparation.

[0049] In summary, in the anti-misassembly tooling for an automotive radar bracket provided in the embodiments of the present invention, by designing the anti-misassembly tooling for the automotive radar bracket in the welding circuit of the radar bracket, when correctly assembled, the radar bracket presses against the touch component, causing the touch component to be connected to the conduction component to conduct the circuit for welding work. Conversely, when misassembled, an open circuit is formed and the welding work cannot be achieved. The present invention can effectively prevent the mixed assembly and misassembly of products, thereby avoiding unnecessary economic losses. Moreover, it has a low development cost, a stable structure, is durable, is simple for workers to operate, and can be applied to various types of radar brackets.

[0050] The above embodiments are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
