Description

Technical Field

[0001] The invention relates to the technical field of vehicle parts detection, and in particular to a device for quickly detecting the quality of a vehicle lamp bracket. Background Art

[0002] Headlight brackets are important parts used to fix and support headlights on cars. They ensure that the headlights can be stably installed in the designated positions of the car and can be adjusted at angles as needed. The design and material selection of headlight brackets are crucial to ensure the normal use of headlights and driving safety.

[0003] Existing headlights use modern manufacturing technology, advanced design concepts and high-quality materials. They are not only beautiful in appearance but also conform to the principles of aerodynamics. Headlights are mainly installed on bumpers or other connecting parts through headlight brackets. The quality of the headlight brackets determines the stability of the headlights. At present, due to the high cost of headlights, the headlights are easily damaged when the vehicle encounters a collision, resulting in a high cost for replacing headlights. Energy-absorbing components are gradually being used, that is, the headlight brackets use structural parts and supporting energy-absorbing parts. The structural parts are used to protect the headlight body. The supporting energy-absorbing parts are connected to the structural parts and bumpers. When the vehicle is hit by an external impact, the supporting energy-absorbing parts absorb energy and are damaged first, reducing the impact force on the structural parts and the headlight body, and reducing the damage to the headlights. During maintenance, only the headlight bracket needs to be replaced, which greatly reduces the maintenance cost.

[0004] The headlight bracket with supporting energy-absorbing parts needs to be strictly controlled in the manufacturing process to ensure the stability of product quality. However, in the prior art, the inspection of the headlight bracket is mainly carried out by inspecting the mold, which is unable to detect and simulate the changes of the headlight bracket when the vehicle is hit, resulting in incomplete quality inspection of the headlight.

[0005] Therefore, technical personnel in this field are committed to developing a device for quickly detecting the quality of a headlight bracket, which can not only detect the external shape of the headlight bracket, but also detect and simulate the changes of the headlight bracket when the vehicle is hit, thereby improving the detection range of the headlight bracket and providing a basis for subsequent improvements to the headlight bracket. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a device for quickly detecting the quality of a headlight bracket, which can not only detect the external shape of the headlight bracket, but also detect and simulate the changes of the headlight bracket when the vehicle is hit, thereby improving the detection range of the headlight bracket and providing a basis for subsequent improvements to the headlight bracket.

[0007] The technical solution of the present invention to solve the above technical problems is as follows:

[0008] A quick quality detection device for a vehicle lamp bracket, comprising:

[0009] A detection mold, wherein the detection mold has a detection cavity, and the detection cavity is adapted to the vehicle lamp bracket;

[0010] A detection core, wherein the detection core is located in the detection cavity and a coil component is installed in the detection core;

[0011] A telescopic component, wherein the telescopic component is mounted on the side wall of the detection mold and a telescopic end of the telescopic component extends into the detection cavity and is connected to the detection core;

[0012] A sliding component, the sliding component is directly opposite to the detection core, and an electromagnetic component cooperating with the coil component is arranged inside the sliding component, and the sliding component is slidably mounted on a support seat;

[0013] A detection component, wherein the detection component is rotatably mounted on the detection mold, and a detection end of the detection component abuts against the energy absorbing member supporting the vehicle lamp bracket;

[0014] A control module, wherein the control module sends a retraction signal to the telescopic component so that the telescopic component drives the detection core to retract, and then the control module transmits a detection current to the coil component and generates a magnetic field. Under the action of the magnetic field force, the electromagnetic component drives the sliding component to move toward the detection mold to hit the headlight bracket. The detection component is used to detect the deformation of the headlight bracket and convert the deformation acting on itself into an electrical signal, which is then transmitted to the control module. The control module determines the quality of the headlight bracket based on the electrical signal.

[0015] The beneficial effects of the above scheme are as follows: the headlight bracket is made of structural parts and supporting energy-absorbing parts. The structural parts are located outside the headlights to fix and protect the headlights. The supporting energy-absorbing parts are mainly used to connect the structural parts and the bumper, etc. The supporting energy-absorbing parts are mostly made of injection molded parts. The headlight bracket is placed in the detection cavity to detect the external shape of the headlight bracket. The gap between the headlight bracket and the detection mold is used to determine whether the external shape of the headlight bracket meets the manufacturing requirements. The detection core is used to simulate the headlight to detect whether the shape of the structural parts meets the requirements.

[0016] When the shape detection of the headlight bracket is completed, the control module sends a retraction signal to the telescopic component. After receiving the retraction signal, the telescopic component controls the telescopic end to move and drive the detection core to retract. Then the control module energizes the coil component in the detection core so that the coil component generates a magnetic field. Since the sliding component is directly opposite to the detection core and an electromagnetic component that cooperates with the coil component is installed in the sliding component, the electromagnetic component drives the sliding component to move toward the coil component and hit the headlight bracket under the action of the magnetic field generated by the coil component to simulate the situation when the vehicle is hit. At this time, the detection end of the detection component abutting against the energy absorbing part of the headlight bracket (i.e., the supporting energy absorbing part) is used to detect the deformation of the supporting energy absorbing part and convert the deformation amount acting on itself into an electrical signal, which is then transmitted to the control module, so as to judge whether the supporting energy absorbing part meets the manufacturing requirements according to the electrical signal generated by the deformation of the supporting energy absorbing part, so as to ensure that the vehicle can absorb energy in time and break when it is hit to achieve the purpose of protecting the structural parts and the headlights;

[0017] The front driving force collision generated by the combination of the coil component and the electromagnetic component is closer to the scene when the headlight bracket is hit in actual work than using the rear driving force (pushing from the back of the sliding component) to push the sliding component to move.

[0018] At the same time, the detection current passed into the coil component can be adjusted according to the actual detection requirements to achieve the generation of magnetic fields with different magnetic field strengths. The electromagnetic component generates different accelerations and terminal velocities under the magnetic action of different magnetic strengths, simulating the deformation of the supporting energy-absorbing parts when the vehicle is subjected to different impacts;

[0019] Furthermore, when the headlight is working, the headlight bracket is in a working environment of 40℃ to 80℃. Since the coil components will generate heat during the detection process and transfer it to the detection core, the temperature around the detection core is relatively high. Combined with the fact that the headlight bracket is in a magnetic field state, the headlight bracket is in a complex electromagnetic environment. Compared with the movement of the rear-wheel drive sliding components, the magnetic field force and temperature are easy to control, which is convenient for accurately simulating the situation under the working state of the headlight. Through the impact of the sliding components and the detection data of the detection components, the performance and quality of the headlight bracket under the working conditions of the headlight can be judged, the detection range of the headlight bracket can be improved, and a basis can be provided for subsequent improvements to the headlight bracket.

[0020] In summary, the inspection mold is used to inspect the external shape of the headlight bracket, and the coil component and the electromagnetic component cooperate to simulate whether the headlight bracket meets the quality requirements when the vehicle is hit to protect the headlight.

[0021] Based on the above technical solution, the present invention can also be improved as follows.

[0022] Furthermore, the detection mold is provided with a leg detection cavity, a plurality of leg detection cavities are communicated with the detection cavity, and a detection pin is installed in the leg detection cavity.

[0023] The beneficial effect of adopting the above further solution is that the bracket detection cavity is used to detect whether the shape of the supporting energy absorbing member meets the manufacturing requirements, and the detection pin is used to detect whether the position of the connecting bolt hole meets the design requirements.

[0024] Furthermore, the detection component includes a detection piece, one end of which is rotatably mounted on the side wall of the detection mold through a rotating rod, and the other end of the detection piece is penetrated by a fixing rod, and the side wall of the detection mold is provided with a fixing hole that cooperates with the fixing rod, and a first pressure strain gauge is installed on the inner wall of the detection piece, and the first pressure strain gauge is abutted against the energy absorbing part supporting the headlight bracket.

[0025] The beneficial effect of adopting the above further scheme is: before placing the headlight bracket, the fixing rod is disengaged from the fixing hole and the detection piece is rotated to the non-working position, so as to facilitate the placement of the headlight bracket. After the headlight bracket is placed, the detection piece is installed to the designated position, so as to facilitate the detection of the deformation of the supporting energy absorbing part.

[0026] Furthermore, the telescopic component comprises a telescopic cylinder, and an output end of the telescopic cylinder extends into the detection cavity and is connected to the detection core.

[0027] The beneficial effect of adopting the above further solution is that the telescopic cylinder drives the detection core to move, thereby avoiding damage to the detection core during the simulated vehicle collision.

[0028] Furthermore, the sliding component includes a sliding rubber block, the electromagnetic component is installed in the sliding rubber block, the sliding rubber block is installed on a sliding base, both ends of the sliding base have guide holes, and the guide column passes through the guide hole and is connected to the support seat.

[0029] The beneficial effect of adopting the above further solution is that the sliding rubber block slides along the guide column to simulate the external force acting on the headlight bracket, thereby improving the detection accuracy and detection range of the headlight bracket.

[0030] Furthermore, a pushing component is installed on the support seat, and an output end of the pushing component is connected to the sliding component.

[0031] The beneficial effect of adopting the above further solution is that the pushing component is used to detect the strength of the vehicle lamp bracket.

[0032] Furthermore, the pushing component includes a pushing torque electric cylinder, and an output end of the pushing torque electric cylinder is connected to the sliding component through a connector.

[0033] The beneficial effect of adopting the above further scheme is: the pushing component is used to simulate the deformation of the supporting energy-absorbing component when the headlight is hit in a non-working state (i.e., at normal temperature). Specifically, the control module controls the output end of the pushing torque electric cylinder to extend quickly, and the output torque acts on the headlight bracket. The quality of the headlight bracket is judged by the deformation data detected by the detection component. At the same time, the change of the headlight bracket when the vehicle is subjected to different impact forces is simulated by continuously changing the output torque. Furthermore, the pushing torque cylinder is also used to detect the structural strength of the headlight bracket. When detecting the strength of the headlight bracket, the control module controls the output torque of the pushing torque electric cylinder and continuously increases it to detect at what output torque the headlight bracket is damaged, thereby judging the structural strength of the headlight bracket, improving the detection range of the headlight bracket, and providing a basis for subsequent improvements to the headlight bracket.

[0034] Furthermore, a second pressure strain gauge and a temperature sensor are installed in the support leg detection cavity, the second pressure strain gauge is in contact with the lamp bracket support energy absorbing member, and the temperature sensor is electrically connected to the control module.

[0035] The beneficial effect of adopting the above further scheme is: after the headlight bracket is placed in the detection cavity, the second pressure strain gauge is used to detect the deformation of the end of each headlight bracket supporting the energy absorbing member (the part connected to the bumper and other components), the second pressure strain gauge converts the deformation of the end of the headlight bracket supporting the energy absorbing member into an electrical signal, and transmits the electrical signal to the control module, the control module determines whether the end of each headlight bracket supporting the energy absorbing member is uniformly stressed according to the electrical signal transmitted by each second strain gauge, and avoids forcibly placing the headlight frame in the detection cavity, which causes the headlight bracket to have internal stress, thereby causing inaccurate detection;

[0036] The temperature sensor is used to detect the ambient temperature near the mold and transmit the temperature signal to the control module. After receiving the temperature signal, the control module determines whether the ambient temperature is appropriate. If the temperature is too high, a first instruction is generated and transmitted to the signal output end of the control module to reduce the current delivered to the coil component to reduce temperature compensation; if the temperature is too low, a second instruction is generated and transmitted to the signal output end of the control module to increase the current delivered to the coil component to increase temperature compensation.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, a quick detection device for the quality of a vehicle lamp bracket includes:

[0047] A detection mold 1, wherein the detection mold 1 has a detection cavity 2, and the detection cavity 2 is adapted to the vehicle lamp bracket;

[0048] A detection core 3, the detection core 3 is located in the detection cavity 2, and a coil component is installed in the detection core 3;

[0049] A telescopic component 4, wherein the telescopic component 4 is mounted on the side wall of the detection mold 1 and the telescopic end of the telescopic component 4 extends into the detection cavity 2 and is connected to the detection core 3;

[0050] A sliding component 5, the sliding component 5 is directly opposite to the detection core 3, and an electromagnetic component cooperating with the coil component is arranged inside the sliding component 5, and the sliding component 5 is slidably mounted on the support seat 6;

[0051] A detection component 7, the detection component 7 is rotatably mounted on the detection mold 1, and a detection end of the detection component 7 abuts against the lamp bracket support energy absorbing member;

[0052] The control module sends a retraction signal to the telescopic component 4 so that the telescopic component 4 drives the detection core 3 to retract. The control module then transmits a detection current to the coil component and generates a magnetic field. Under the action of the magnetic field force, the electromagnetic component drives the sliding component 5 to move toward the detection mold 1 to hit the headlight bracket. The detection component 7 is used to detect the deformation of the headlight bracket and convert the deformation acting on itself into an electrical signal, which is then transmitted to the control module. The control module determines the quality of the headlight bracket based on the electrical signal.

[0053] In the present invention, the headlight bracket is made of structural parts and supporting energy absorbing parts. The structural parts are located outside the headlights to fix and protect the headlights. The supporting energy absorbing parts are mainly used to connect the structural parts and the bumpers, etc. The supporting energy absorbing parts can be made of injection molded parts. The headlight bracket is placed in the detection chamber 2 to detect the external shape of the headlight bracket. The gap between the headlight bracket and the detection mold 1 is used to determine whether the external shape of the headlight bracket meets the manufacturing requirements. When the headlight bracket appearance is detected, the detection core 3 is used to simulate the headlight to detect whether the shape of the structural parts meets the requirements.

[0054] When the appearance inspection of the headlight bracket is completed, the telescopic component 4 drives the inspection core 3 to retract, and then the control module (not shown in the figure) energizes the coil component in the inspection core 3 so that the coil component generates a magnetic field. Since the sliding component 5 is directly opposite to the inspection core 3 and an electromagnetic component that cooperates with the coil component is installed in the sliding component 5, the electromagnetic component drives the sliding component 5 to move toward the coil component under the action of the magnetic field generated by the coil component and hits the headlight bracket to simulate the situation when the vehicle is hit. At this time, the detection end of the detection component 7 abutting against the headlight bracket energy absorbing member (i.e., the headlight bracket support energy absorbing member) is used to detect the deformation of the support energy absorbing member and transmit the detection information to the control module (not shown in the figure), so as to judge whether the support energy absorbing member meets the manufacturing requirements according to the deformation of the support energy absorbing member, so as to ensure that the vehicle can absorb energy and break in time when it is hit to achieve the purpose of protecting the structural parts and the headlights;

[0055] At the same time, the current flowing into the coil component can be adjusted according to the actual detection requirements to simulate the deformation of the supporting energy-absorbing parts when the vehicle is subjected to different impacts;

[0056] Furthermore, when the headlight is working, the headlight bracket is in a working environment of 40°C to 80°C. Since the coil component will generate heat during the detection process and transfer it to the detection core 3, the temperature around the detection core 3 is relatively high. At this time, it is used to simulate the situation when the headlight is in working condition. Through the impact of the sliding component 5 and the detection data of the detection component 7, the performance and quality of the headlight bracket under the working condition of the headlight can be judged, the detection range of the headlight bracket can be improved, and a basis can be provided for the subsequent improvement of the headlight bracket.

[0057] like Figure 1 , Figure 2 As shown, in some embodiments, the detection mold 1 is installed on the base, and the detection mold 1 has a support leg detection cavity 8. In this embodiment, four support leg detection cavities 8 are provided, and the four support leg detection cavities 8 are all arranged on the outside of the detection cavity 2. Multiple support leg detection cavities 8 are communicated with the detection cavity 2, and detection pins 9 are installed in the support leg detection cavity 8. The detection pins 9 are used to detect whether the mounting holes on the support energy absorbing parts meet the manufacturing requirements.

[0058] A second pressure strain gauge and a temperature sensor are installed in the support leg detection cavity 8. The second pressure strain gauge abuts against the headlight bracket support energy absorbing member. The second pressure strain gauge can be a resistive pressure strain gauge or a capacitive pressure strain gauge. The second pressure strain gauge is used to detect the stress of each support energy absorbing member. Since the support energy absorbing member has a certain deformation capacity, in order to avoid the detection personnel forcibly placing the headlight bracket into the detection cavity 2 to meet the shape of the headlight bracket, the headlight bracket has a certain internal stress, resulting in inaccurate data during subsequent headlight bracket detection. At the same time, when the headlight bracket itself has internal stress due to process and other problems during the manufacturing process of the headlight bracket, it can be detected and analyzed and judged through the data detection and analysis of each second pressure strain gauge, thereby improving the quality detection range of the headlight bracket.

[0059] The temperature sensor is used to detect the ambient temperature near the mold 1 and transmit the temperature signal to the control module. After receiving the temperature signal, the control module determines whether the ambient temperature is appropriate. If the temperature is too high, a first instruction is generated and transmitted to the signal output end of the control module to reduce the current delivered to the coil component to reduce temperature compensation; if the temperature is too low, a second instruction is generated and transmitted to the signal output end of the control module to increase the current delivered to the coil component to increase temperature compensation.

[0060] like Figure 1 , Figure 2As shown, in some embodiments, the detection component 7 includes a detection piece 10, one end of the detection piece 10 is rotatably mounted on the side wall of the detection mold 1 through a rotating rod 11, the other end of the detection piece 10 is penetrated by a fixing rod 12, and the side wall of the detection mold 1 is provided with a fixing hole that cooperates with the fixing rod 12. Specifically, the rotating rod 11 is fixedly mounted on the side wall of the detection mold 1, one side of the detection piece 10 is sleeved on the rotating rod 11 so that the detection piece 10 can rotate around the rotating rod 11, the other end of the detection piece 10 is penetrated by a fixing rod 12, and a return spring is also installed between the fixing rod 12 and the detection piece 10. During the detection process, the detection piece 10 rotates around the rotating rod 11 so that the end of the fixing rod 12 is inserted into the fixing hole, so that the detection piece 10 is in the working position.

[0061] A first pressure strain gauge is installed on the inner wall of the detection piece 10, and the first pressure strain gauge abuts against the lamp bracket support energy absorbing member. In this embodiment, the first pressure strain gauge is electrically connected to the control module, and the first pressure strain gauge can be a resistive pressure strain gauge or a capacitive pressure strain gauge. When the detection piece 10 is in the working position, the first pressure strain gauge mainly abuts against the side wall of the support energy absorbing member, which is conducive to detecting the deformation of the support energy absorbing member.

[0062] In another embodiment, the telescopic component 4 includes a telescopic cylinder 13, which is connected to the control module. The telescopic cylinder 13 is installed on the side wall of the detection mold 1 through a cylinder mounting part. The output end of the telescopic cylinder 13 extends into the detection cavity 2 and is connected to the detection core 3. The telescopic cylinder 13 drives the detection core 3 to move to prevent the sliding component 5 from causing damage to the detection core 3 when it hits the headlight bracket.

[0063] like Figure 1 , Figure 3 As shown, in some embodiments, the sliding component 5 includes a sliding rubber block 14, an electromagnetic component is installed in the sliding rubber block 14, the sliding rubber block 14 is installed on a sliding base 15, the sliding base 15 is installed on a base, and the sliding base 15 has guide holes at both ends, and a guide column 16 passes through the guide hole and is connected to the support seat 6. During operation, when the control module passes current into the coil component, the coil component generates a magnetic field, and the electromagnetic component drives the sliding rubber block 14 to move along the guide column 16 under the action of the magnetic field force to hit the headlight bracket. The control module controls the input current to control the magnetic field force generated by the coil component, thereby adjusting the impact force of the sliding rubber block 14.

[0064] In this embodiment, a pushing component 17 is also installed on the support seat 6, and the output end of the pushing component 17 is connected to the sliding component 5. Specifically, the pushing component 17 includes a pushing torque electric cylinder, and the output end of the pushing torque electric cylinder is connected to the sliding component 5 through a connector 18. When the structural strength of the lamp bracket is detected when the lamp is working, the output end of the pushing torque cylinder is disconnected from the sliding rubber block 14, and when the structural strength of the lamp bracket is detected when the lamp is not working, the output end of the pushing torque cylinder is connected to the sliding rubber block 14 through the connector 18.

[0065] The pushing torque electric cylinder is used to simulate the deformation of the supporting energy-absorbing parts when the headlight is hit in a non-working state (i.e., at normal temperature). Specifically, the control module controls the output end of the pushing torque electric cylinder to extend quickly, and the output torque acts on the headlight bracket. The quality of the headlight bracket is judged by the deformation data detected by the detection component 7. At the same time, the output torque is continuously changed to simulate the change of the headlight bracket when the vehicle is subjected to different impact forces. Furthermore, the pushing torque cylinder is also used to detect the structural strength of the headlight bracket. When detecting the strength of the headlight bracket, the control module controls the output torque of the pushing torque electric cylinder and continuously increases it to detect at what output torque the headlight bracket is damaged, thereby judging the structural strength of the headlight bracket, improving the detection range of the headlight bracket, and providing a basis for subsequent improvements to the headlight bracket.
