Description

Technical Field

[0001] This utility model relates to the field of vehicle door handle testing technology, specifically a dual-capacitor commercial vehicle door handle testing platform with a dual-clamp structure. Background Technology

[0002] Commercial vehicles, such as trucks, buses, and special-purpose vehicles, are core tools for transportation and production operations. The reliability and safety of their components directly affect the operational efficiency of the vehicles and the safety of the drivers and passengers. Door handles, as key components of commercial vehicle bodies, play a crucial role in the core functions of opening, closing, and locking doors. Furthermore, with the development of automotive electronics and intelligence, modern commercial vehicle door handles often integrate electronic sensing elements, such as capacitive sensors, to achieve functions such as keyless entry and touch unlocking, further enhancing ease of use.

[0003] While existing technologies can test capacitive commercial vehicle door handles, most existing test benches have single-clamp or simple fixed structures, which are not convenient for testing capacitive commercial vehicle door handles with double clamps. This can lead to significant limitations in use. Furthermore, the fixed clamp structure only fits specific door handle models, resulting in poor practicality when testing capacitive commercial vehicle door handles of different sizes and shapes. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a dual-clip structure test bench for commercial vehicle door handles with dual clamps. It can effectively solve the problem that although existing test benches can test capacitive commercial vehicle door handles, most of them have single clamps or simple fixed structures, which are not convenient for testing dual-clip capacitive commercial vehicle door handles. This can lead to a large limitation in use. In addition, the fixed clamp structure can only be adapted to specific door handle models. It is difficult to test capacitive commercial vehicle door handles of different sizes and shapes, resulting in poor practicality.

[0005] The technical solution adopted by this utility model is: a dual-capacitor commercial vehicle door handle test bench with a dual-clamp structure, including a test bench body and a limiting component. The test bench body is fixedly installed with a clamping platform, a wire harness assembly, a movable clamping assembly and a detection seat. The end of the clamping platform away from the test bench body is clamped to the dual-capacitor commercial vehicle door body. The end of the dual-capacitor commercial vehicle door body near the wire harness assembly is provided with a connecting wire harness. The end of the connecting wire harness away from the dual-capacitor commercial vehicle door body is provided with a connector.

[0006] The movable clamping assembly includes a push rod body and a slide rail. A connecting column is fixedly installed at one end of the push rod body near the slide rail, and a slide table and a fixing plate are fixedly installed at the other end of the connecting column away from the push rod body. An installation groove is provided on the inner edge of the fixing plate.

[0007] The limiting component includes a limiting sleeve, which is installed by insertion with the fixing plate through a mounting groove. A plastic sleeve is fixedly installed at the end of the limiting sleeve away from the moving clamping component. Slot 1 and Slot 2 are provided on the inner edge of the limiting sleeve.

[0008] Preferably, a positioning post is fixedly installed on the card platform, the positioning post is adapted to the dual-capacitor commercial vehicle door body, an mounting plate is fixedly installed on the end of the card platform near the wiring harness assembly, and a protective sleeve is fixedly installed on the end of the mounting plate away from the test platform body, the protective sleeve is in contact with the connecting wiring harness.

[0009] Through the above technical solution, by adapting the positioning post to the dual-capacitor commercial vehicle door body, the positioning post can be used to position the dual-capacitor commercial vehicle door body during testing, which facilitates the placement of the dual-capacitor commercial vehicle door body on the card table. In addition, the protective sleeve design can protect the connecting wire harness and prevent wear at the connection point, thus avoiding affecting its normal use.

[0010] Preferably, the wire harness assembly includes a wire harness base, with a positioning bolt threaded to one of the four corners of the wire harness base and extending to the inner surface of the test bench body. A slant plate and a protective sleeve are fixedly installed at the end of the wire harness base away from the test bench body, and the connecting wire harness is in contact with the protective sleeve.

[0011] The above technical solution guides the wiring harness by fixing it to the test bench body with a positioning bolt, preventing excessive bending of the harness. In addition, the protective sleeve fits the harness, which not only fixes the position of the harness to prevent shaking, but also reduces friction between the harness and the wiring harness, thus preventing wear and tear on the wiring harness during testing.

[0012] Preferably, two identical wire harness assemblies are provided, and both wire harness assemblies are attached to the connecting wire harness.

[0013] The above technical solution uses two wire harness components to attach and connect the wire harness from different positions to form a multi-point fixing structure. This can disperse the tension of the wire harness, avoid excessive local stress caused by fixing at a single point, keep the wire harness in a natural and relaxed state, reduce signal interference caused by pulling, and improve the accuracy of test data.

[0014] Preferably, the end of the limiting sleeve away from the plastic sleeve has an installation hole, and a positioning bolt is threaded through the fixing plate and the installation hole at the outer edge of the fixing plate.

[0015] With the above technical solution, during testing, the limiting sleeve can be inserted into the mounting slot, and the positioning bolt 2 can be locked through the fixing plate and the mounting hole to firmly fix the limiting component and prevent the limiting sleeve from shifting due to vibration during testing. The detachable structure of the limiting sleeve makes it easy to replace different limiting sleeves according to the connector specifications, enhancing the versatility of the equipment, thereby realizing quick switching between dual-head and single-head, and improving the versatility of the overall testing device.

[0016] Preferably, a detection head is fixedly installed on the detection seat, the detection head and the connecting head are located on the same horizontal plane, and a gripper is fixedly installed on the end of the fixing plate away from the limiting component, the gripper being adapted to the detection seat.

[0017] The above technical solution, with the detection head and connector on the same horizontal plane, allows the clamp to dock with the detection seat when the fixed plate slides above the slide rail, enabling the two to be inserted and avoiding poor contact caused by misalignment.

[0018] Preferably, the diameter of the plastic sleeve is larger than the diameter of the connector, the first slot and the second slot are interconnected, and the first slot and the second slot are the same size as the connector.

[0019] The above technical solution, by using a plastic sleeve with a diameter larger than the connector, can form a protective wrap around the connector during docking, avoiding collision damage. It can also limit the connector, preventing it from easily detaching from slot one and slot two. Furthermore, the interconnected slot one and slot two are the same size as the connector, which can help position the connector.

[0020] Compared with the prior art, this utility model provides a dual-capacitor commercial vehicle door handle test stand with a dual-clamp structure, which has the following advantages:

[0021] 1. This dual-capacitor commercial vehicle door handle test bench with a dual-clamp structure, through the cooperation of the limiting sleeve and the mounting groove, allows the limiting sleeve to be inserted into the mounting groove, and the positioning bolt 2 passes through the fixing plate and the mounting hole to lock it, which can firmly fix the limiting component and prevent the limiting sleeve from shifting due to vibration during testing. The detachable structure of the limiting sleeve makes it easy to replace different limiting sleeves according to the connector specifications, enhancing the versatility of the equipment, thereby realizing quick switching between dual-head and single-head, and improving the versatility of the overall testing device in use;

[0022] 2. This dual-capacitor commercial vehicle door handle test stand with a dual-clamp structure has a plastic sleeve with a diameter larger than the connector head, which can form a protective wrap around the connector head during docking to avoid collision damage. At the same time, it can also limit the connector head to prevent it from easily detaching from slot one and slot two. Furthermore, the interconnected slot one and slot two are the same size as the connector head, which can play a positioning role for the connector head. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: As Figure 1-8As shown, the present invention provides a dual-capacitor commercial vehicle door handle test bench with a dual-clamp structure, including a test bench body 1 and a limiting component 13. The test bench body 1 is fixedly installed with a clamping platform 2, a wire harness component 9, a movable clamping component 10 and a detection seat 11. The end of the clamping platform 2 away from the test bench body 1 is clamped to the dual-capacitor commercial vehicle door body 6. The end of the dual-capacitor commercial vehicle door body 6 near the wire harness component 9 is provided with a connecting wire harness 7, and the end of the connecting wire harness 7 away from the dual-capacitor commercial vehicle door body 6 is provided with a connector 8.

[0034] The movable clamping assembly 10 includes a push rod body 1001 and a slide rail 1002. A connecting post 1003 is fixedly installed at one end of the push rod body 1001 near the slide rail 1002. A slide table 1004 and a fixing plate 1005 are fixedly installed at the other end of the connecting post 1003 away from the push rod body 1001. An installation groove 1006 is provided at the inner edge of the fixing plate 1005.

[0035] The limiting component 13 includes a limiting sleeve 1301, which is installed by insertion with the fixing plate 1005 through the mounting groove 1006. A plastic sleeve 1303 is fixedly installed at the end of the limiting sleeve 1301 away from the moving clamping component 10. A slot 1 1304 and a slot 2 1305 are provided on the inner edge of the limiting sleeve 1301.

[0036] Specifically, a positioning post 3 is fixedly installed on the card holder 2. The positioning post 3 is adapted to the dual-capacitor commercial vehicle door body 6. A mounting plate 4 is fixedly installed on the end of the card holder 2 near the wiring harness assembly 9. A protective sleeve 5 is fixedly installed on the end of the mounting plate 4 away from the test stand body 1. The protective sleeve 5 is in contact with the connecting wire harness 7. The advantage is that, through the design of the positioning post 3 adapting to the dual-capacitor commercial vehicle door body 6, the positioning post 3 can be used to position the dual-capacitor commercial vehicle door body 6 during testing, which makes it easy to place the dual-capacitor commercial vehicle door body 6 on the card holder 2. In addition, the design of the protective sleeve 5 can protect the connecting wire harness 7 and prevent wear at the connection point, thus affecting its normal use.

[0037] Specifically, the cable harness assembly 9 includes a cable harness holder 901. Positioning bolts 902, extending through to the inner surface of the test bench body 1, are threaded to the four corners of the cable harness holder 901. An inclined plate 903 and a protective sleeve 904 are fixedly installed at the end of the cable harness holder 901 away from the test bench body 1. The connecting cable harness 7 fits snugly against the protective sleeve 904. The advantage is that by fixing the cable harness holder 901 to the test bench body 1 via the positioning bolts 902, the direction of the connecting cable harness 7 can be guided, preventing excessive bending of the cable harness. Furthermore, the protective sleeve 904 fits snugly against the cable harness, fixing its position to prevent shaking and reducing friction between the cable harness and the cable harness holder 901, thus preventing wear and tear on the connecting cable harness 7 during testing.

[0038] Specifically, there are two identical wire harness assemblies 9, both of which are attached to the connecting wire harness 7. The advantage is that by attaching the two wire harness assemblies 9 to the connecting wire harness 7 from different positions, a multi-point fixing structure is formed, which can disperse the tension of the wire harness, avoid excessive local stress caused by single-point fixing, keep the wire harness in a natural and relaxed state, reduce signal interference caused by pulling, and improve the accuracy of test data.

[0039] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0040] Specifically, the end of the limiting sleeve 1301 away from the plastic sleeve 1303 has an installation hole 1302. A positioning bolt 1007 is threaded through the fixing plate 1005 and the installation hole 1302 at the outer edge of the fixing plate 1005. The advantage is that during testing, the limiting sleeve 1301 can be inserted into the installation groove 1006, and the positioning bolt 1007 can be locked through the fixing plate 1005 and the installation hole 1302, which can firmly fix the limiting component 13 and prevent the limiting sleeve 1301 from shifting due to vibration during testing. The detachable structure of the limiting sleeve 1301 makes it easy to replace different limiting sleeves 1301 according to the specifications of the connector 8, enhancing the versatility of the equipment, thereby realizing quick switching between dual-head and single-head, and improving the versatility of the overall testing device.

[0041] Specifically, a detection head 12 is fixedly installed on the detection seat 11. The detection head 12 and the connector 8 are located on the same horizontal plane. A gripper 1008 is fixedly installed on the end of the fixing plate 1005 away from the limiting component 13. The gripper 1008 is adapted to the detection seat 11. The advantage is that, by designing that the detection head 12 and the connector 8 are on the same horizontal plane, when the fixing plate 1005 slides above the slide rail 1002, the gripper 1008 can dock with the detection seat 11, which can assist the two in plugging in and avoid poor contact caused by misalignment.

[0042] Specifically, the diameter of the plastic sleeve 1303 is larger than the diameter of the connector 8. Slot 1 1304 and Slot 2 1305 are interconnected. Slot 1 1304 and Slot 2 1305 are the same size as the connector 8. The advantage is that, since the diameter of the plastic sleeve 1303 is larger than that of the connector 8, it can form a protective enclosure for the connector 8 during docking, avoiding collision damage. At the same time, it can also limit the connector 8, preventing it from easily detaching from Slot 1 1304 and Slot 2 1305. Furthermore, the interconnected Slot 1 1304 and Slot 2 1305 are the same size as the connector 8, which can play a positioning role for the connector 8.

[0043] Working Principle: During use, the positioning post 3 is designed to fit the dual-capacitor commercial vehicle door body 6. During testing, the positioning post 3 positions the dual-capacitor commercial vehicle door body 6, facilitating its placement on the test stand 2. Furthermore, the protective sleeve 5 protects the connecting harness 7, preventing wear at the connection points and ensuring its proper function. The harness is fixed to the test stand body 1 via the harness holder 901 and positioning bolt 902, guiding the wiring harness 7 and preventing excessive bending. The wire harness is secured with a protective sleeve 904, which not only fixes the harness position to prevent shaking but also reduces friction between the harness and the harness holder 901. This prevents wear on the connecting harness 7 during testing. Two harness assemblies 9 attach to the connecting harness 7 from different positions, forming a multi-point fixing structure. This disperses the tension of the harness, avoiding excessive localized stress caused by single-point fixing, allowing the harness to maintain a natural, relaxed state, reducing signal interference caused by pulling, and improving the accuracy of test data. During testing, the limiting sleeve 1301 can be inserted into the mounting slot. After 1006, the second positioning bolt 1007 passes through the fixing plate 1005 and locks into the mounting hole 1302, which can firmly fix the limiting component 13 and prevent the limiting sleeve 1301 from shifting due to vibration during testing. The detachable structure of the limiting sleeve 1301 makes it easy to replace different limiting sleeves 1301 according to the specifications of the connector 8, enhancing the versatility of the equipment and realizing quick switching between dual-head and single-head operation, thus improving the versatility of the overall testing device. The design of the detection head 12 and the connector 8 being on the same horizontal plane allows the fixing plate 1005 to be positioned on the slide rail 1. When sliding upwards, the gripper 1008 can dock with the detection seat 11, allowing the two to be inserted and avoiding poor contact due to misalignment. Since the plastic sleeve 1303 has a larger diameter than the connector 8, it can form a protective enclosure for the connector 8 during docking to avoid collision damage. At the same time, it can also limit the connector 8 to prevent it from easily disengaging from slot 1304 and slot 21305. Furthermore, the interconnected slot 1304 and slot 21305 are the same size as the connector 8 and can play a positioning role for the connector 8.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
