Description

Technical Field

[0001] This application relates to the field of automotive parts testing technology, specifically to a door outward opening durability testing device. Background Technology

[0002] The automotive door closure system mainly consists of doors, front hood, and tailgate. To ensure high reliability of the door system during daily use, durability testing is required.

[0003] Car door handles come in various structural forms, such as traditional non-concealed, concealed, and semi-concealed types. Each type of handle has different unlocking and opening methods. Semi-concealed door handles include at least two unlocking methods, such as mechanical unlocking and electronic unlocking. Mechanical unlocking allows the door to be unlocked and opened by directly pulling the handle. Electronic unlocking requires pressing a switch button on the handle to unlock the door, and then pulling the handle opens the door.

[0004] Therefore, it is necessary to design a door outward opening durability test device that can adapt to multiple unlocking and opening methods in order to improve the utilization rate of the test device. Utility Model Content

[0005] To address the problem of low utilization rate caused by the low compatibility of outward-opening vehicle door durability testing devices, this application provides an outward-opening vehicle door durability testing device.

[0006] This application provides a side impact reinforcement structure for a vehicle body, including a base, a first drive mechanism, a frame member, and a second drive mechanism. The first drive mechanism is connected to the base, and the frame member is connected to the first drive mechanism. The first drive mechanism is used to drive the frame member to switch between a first preset position and a second preset position. The second drive mechanism is connected to the frame member, and when the frame member is in the first preset position, the second drive mechanism is configured to press, contact, and engage with a door handle.

[0007] According to the aforementioned technical means, by configuring the second drive mechanism to have pressing contact and snap-on hooking actions, the snap-on hooking action can be adapted to snap onto different door handles such as conventional, concealed, and semi-concealed structures. The pressing contact action can be used to touch a button, thereby releasing the safety lock or directly unlocking the concealed and semi-concealed door handles, facilitating snap-on adaptation of the door handles through the snap-on hooking action. In this way, the first drive mechanism located on the base can move from a first preset position to a second preset position via the frame component, thereby driving the door to open and completing the automated durability test of the outward opening of the door.

[0008] Thus, this application effectively solves the dual-action testing challenge of semi-concealed door handles. Through the coordinated control of frame positioning and composite drive, it achieves accurate simulation of both mechanical and electronic unlocking modes. Furthermore, this door outward opening durability testing device can flexibly adapt to structures such as conventional and concealed door handles according to different execution actions, thereby being compatible with the testing requirements of door handles of different structural forms and significantly improving the utilization rate of automated testing devices and the accuracy of test data.

[0009] Optionally, the second drive mechanism includes a hook, a first drive assembly, and a second drive assembly. The first drive assembly is connected to the frame member, and the second drive assembly is connected to at least the first drive assembly and the hook. One of the first and second drive assemblies is configured to drive the hook to perform a pressing action, and the other is configured to drive the hook to perform a latching action.

[0010] According to the above technical means, through the setting of the first driving component and the second driving component, the coordinated work of the two driving components enables a single hook to complete a combination of actions in different directions, which facilitates the flexible configuration of the second driving mechanism and helps to improve the adaptability of the test decoration.

[0011] Optionally, the second drive component is used to drive the hook to extend and retract in a straight line.

[0012] Based on the above-mentioned technical means, the linear motion trajectory can precisely control the displacement of the hook, ensuring the repeatability of the pressing or hooking action, and adapting to the testing needs of semi-concealed door handles of different sizes or shapes.

[0013] Optionally, the first driving assembly includes a first linear drive member, a first support, and a second support. The first linear drive member is connected to the frame member via the first support, the second support is connected to the frame member, and the second driving assembly is hinged to the second support. The driving end of the first linear drive member is hinged to the second driving assembly, and is used to drive the hook to rotate and switch between a third preset position and a fourth preset position.

[0014] Based on the aforementioned technical means, the linear drive mode can be converted into a rotational displacement mode with a suitable amplitude to meet the precise switching between the alignment action of the hook contact or the hooking action, and can be adapted to semi-concealed door handles with different unlocking methods.

[0015] Optionally, the second drive assembly includes a rocker arm, a guide block, and a second linear drive. The rocker arm is hinged to the second support, and one end of the rocker arm is hinged to the drive end of the first linear drive. The other end of the rocker arm is used to connect to the guide block, which has a guide hole. The second linear drive is connected to the rocker arm, and the drive end of the second linear drive is connected to the hook via the guide hole, for driving the hook to move axially and retract along the guide hole.

[0016] Based on the above technical means, two motion modes can be integrated in one drive mechanism, which effectively solves the incompatibility problem of test devices caused by the difference in unlocking methods of semi-concealed door handles. At the same time, the modular design makes the extension stroke and rotation angle of the hook adjustable to meet the size change requirements of door handles of different models, which significantly improves the versatility and testing efficiency of the test device.

[0017] Optionally, the second drive assembly includes an extension rod along the axial direction of the guide hole, and the guide block and the rocker are spaced apart and connected by the extension rod.

[0018] Based on the aforementioned technical means, the function of the extension rod is to maintain the relative position between the guide block and the rocker arm, and to prevent structural displacement due to external forces.

[0019] Optionally, the first linear drive is a linear motor or a cylinder. And / or,

[0020] The second linear drive component is a linear motor or cylinder.

[0021] Based on the aforementioned technical methods, the modular combination design of linear motors and / or cylinders not only simplifies the spatial layout of the drive mechanism but also reduces equipment maintenance costs while ensuring motion accuracy through the complementary characteristics of pneumatic and electric drives. For example, in high-temperature or low-temperature testing environments, cylinders exhibit better resistance to temperature interference than traditional electric drive mechanisms.

[0022] Optionally, the frame component includes a support frame, a support arm, and a buffer positioning member. The support frame is detachably connected to the second drive mechanism. One end of the support arm is connected to the support frame, and the other end of the support arm is connected to the drive end of the first drive mechanism, so that the first drive mechanism drives the support frame to move and switch between a first preset position and a second preset position. The buffer positioning member is connected to the support frame. When the support frame is in the first preset position, the buffer positioning member is located on the side of the support frame facing the door handle, and the buffer positioning member is used to abut against the door.

[0023] Based on the aforementioned technical means, by configuring the bracket frame and the second drive mechanism to be detachably connected, it is convenient to adjust the multiple installation positions of the second drive structure and the bracket frame to adapt to door handles of different heights and positions. Since the positioning component makes buffer contact with the door, it will not cause wear to the exterior finish of the door (such as the paint).

[0024] Optionally, the buffer positioning component includes a third support and a buffer wheel. When the bracket frame is in the first preset position, the third support is located on the side of the bracket frame facing the door handle, and the third support is connected to the bracket frame. The buffer wheel is connected to the end of the third support away from the bracket frame, for buffering and supporting the door.

[0025] Based on the above technical means, the cooperation between the buffer wheel and the third support not only achieves flexible buffering when the door is closed, but also ensures precise control of the door opening and closing position during the test, and avoids damage to the door's exterior surface by sliding friction and rigid contact.

[0026] Optionally, the first drive mechanism is a geared motor, used to drive the bracket frame to rotate and switch between a first preset position and a second preset position.

[0027] According to the above-mentioned technical means, by setting the first drive mechanism as a geared motor, the power device can reduce the output speed and increase the torque, thereby providing stable power for the rotation switching of the bracket frame between the first preset position and the second preset position.

[0028] The beneficial effects of this application are:

[0029] By employing coordinated control of frame positioning and composite drive, this device achieves precise simulation of both mechanical and electronic unlocking modes, effectively solving the dual-action testing challenge of semi-concealed door handles. Furthermore, this door outward opening durability testing device can flexibly adapt to structures such as conventional and concealed door handles according to different execution actions, thus meeting the testing requirements of door handles with different structural forms and significantly improving the utilization rate of automated testing equipment and the accuracy of test data.

[0046] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0047] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0048] To address the problem of low utilization rate caused by the low compatibility of outward-opening vehicle door durability testing devices, this application provides an outward-opening vehicle door durability testing device, such as... Figure 1 The outward-opening durability testing device 100 for car doors (hereinafter referred to as the testing device) includes a base 10, a first drive mechanism 20, a frame member 30, and a second drive mechanism 40. The first drive mechanism 20 is connected to the base 10, and the frame member 30 is connected to the first drive mechanism 20. The first drive mechanism 20 is used to drive the frame member 30 to switch between a first preset position and a second preset position. The second drive mechanism 40 is connected to the frame member 30. When the frame member 30 is in the first preset position, the second drive mechanism 40 is configured to press and engage the door handle 201.

[0049] The base 10 refers to the basic support structure that supports the test device, and is used for supporting and positioning the test device. It can be fixedly connected by frame components or plate components to form the main structure of the base 10, which is used for positioning and installing the first drive mechanism 20, and at the same time supports other structural components.

[0050] The first drive mechanism 20 can be a linear drive structure or a rotary drive structure, as long as it can drive the frame member 30 to switch between a first preset position and a second preset position. For example, the first drive mechanism 20 can be a rotary motor structure to drive the frame member 30 to rotate and switch between the first preset position and the second preset position. Alternatively, the first drive mechanism 20 can also be a linear drive structure such as a cylinder or a linear motor to drive the frame member 30 to move and switch between the first preset position and the second preset position.

[0051] For example, the first drive mechanism 20 is a geared motor, including a rotary motor and a reduction gear set, so as to reduce the speed of the rotary motor through the reduction gear set, thereby driving the connected frame member 30 to reciprocate stably between a first preset position and a second preset position, and having a high torque.

[0052] In the embodiments of this application, such as Figure 1 As shown, the first preset position is the position of the frame member 30 near the door 200. At the first preset position, the actuating component of the second drive mechanism 40 connected to the frame member 30 can engage and hook the door handle 201, thereby unlocking and opening the door 200 through the door handle 201, simulating a mechanical unlocking operation. Alternatively, at the first preset position, the actuating component of the second drive mechanism 40 can also move slightly to press the unlock button on the door handle 201 to unlock the door 200. Subsequently, it can engage and hook the door handle 201 to open the unlocked door 200, simulating an electronic unlocking operation.

[0053] For example, during the outward opening durability test of the vehicle door, the first drive mechanism 20 moves the frame member 30 to a first preset position. At the first preset position, the actuating component of the second drive mechanism 40 can optionally perform an action of engaging and hooking the door handle 201, thereby unlocking the door handle 201 and opening the vehicle door. Alternatively, at the first preset position, the second drive mechanism 40 can first perform an action of pressing and contacting the door handle 201, thereby unlocking the vehicle door by pressing a button on the door handle 201 before engaging and hooking the door handle 201. After the second drive mechanism 40 engages and hooks the door handle 201, the first drive mechanism 20 moves the frame member 30 and the second drive mechanism 40 to a second preset position, thereby opening the vehicle door 200 and completing the durability test of one opening action of the vehicle door 200.

[0054] Thus, by configuring the second drive mechanism 40 to have pressing contact and snap-on hooking actions, the snap-on hooking action can be adapted to snap onto different door handles 201 such as conventional structure, concealed structure, and semi-concealed structure, while the pressing contact action can be used to touch a button to release the safety lock state of the concealed and semi-concealed door handles 201 or to unlock them directly, facilitating snap-on adaptation of the door handles 201 through the snap-on hooking action. In this way, the first drive mechanism 20 located on the base 10 can be moved from a first preset position to a second preset position through the frame member 30, thereby driving the door 200 to open to complete the automated durability test of the door opening outwards.

[0055] Through the above technical solution, this application effectively solves the dual-action testing problem of semi-concealed door handles 201. By coordinating frame positioning and composite drive control, it achieves accurate simulation of both mechanical unlocking and electronic unlocking modes. Furthermore, the door outward opening durability testing device 100 can flexibly adapt to structures such as conventional door handles 201 and concealed door handles 201 according to different execution actions, thereby being compatible with the testing requirements of door handles of different structural forms and significantly improving the utilization rate of automated testing devices and the accuracy of test data.

[0056] Among them, such as Figure 1 and Figure 2 As shown, the frame component 30 includes a support frame 31 and a support arm 32. The support frame 31 is detachably connected to the second drive mechanism 40. One end of the support arm 32 is connected to the support frame 31, and the other end of the support arm 32 is connected to the drive end of the first drive mechanism 20, so that the first drive mechanism 20 drives the support frame 31 to move and switch between a first preset position and a second preset position.

[0057] The bracket frame 31 refers to the frame structure used to support and fix other components. By configuring the bracket frame 31 to be detachably connected to the second drive mechanism 40, it is convenient to adjust the multiple installation positions of the second drive mechanism 40 and the bracket frame 31 to adapt to door handles 201 at different heights and positions. The load-bearing arm 32 refers to the force-transmitting component connecting the first drive mechanism 20 and the bracket frame 31. While supporting and connecting the bracket frame 31 and the second drive mechanism 40, the load-bearing arm 32 allows for flexible adjustment of the installation position and spacing between the bracket frame 31 and the first drive mechanism 20.

[0058] Taking the first drive mechanism 20 as an example, which can drive the bearing arm 32 and the support frame 31 to rotate and switch between the first preset position and the second preset position, the rotation displacement radius of the support frame 31 can be flexibly adjusted by the bearing arm 32.

[0059] For example, such as Figure 2 As shown, the frame member 30 also includes a buffer positioning member 33, which is connected to the bracket frame 31. When the bracket frame 31 is in the first preset position, the buffer positioning member 33 is located on the side of the bracket frame 31 facing the door handle, and the buffer positioning member 33 is used to abut against the door.

[0060] Specifically, by setting the buffer positioning member 33, after the second drive mechanism 40 engages and hooks the door handle 201, the buffer positioning member 33 abuts against the door 200 and the bracket frame 31, preventing the second drive mechanism 40 from wobbling relative to the door handle 201 and the door at the door handle 201. When the bracket frame 31 moves the door from the first preset position to the second preset position, the bracket frame 31 drives the door 200 to open synchronously through the second drive mechanism 40. When the bracket frame 31 moves from the second preset position to the first preset position, the bracket frame 31 moves the door 200 from the open state to the locked state through the buffer positioning member 33, thus completing one cycle of the door opening test. During this test, because the positioning member makes buffer contact with the door 200, it will not cause wear to the exterior surface (such as the paint) of the door 200.

[0061] Specifically, such as Figure 2 As shown, the buffer positioning member 33 includes a third support 331 and a buffer wheel 332. When the bracket frame 31 is in the first preset position, the third support 331 is located on the side of the bracket frame 31 facing the door handle, and the third support 331 is connected to the bracket frame 31. The buffer wheel 332 is connected to the end of the third support 331 away from the bracket frame 31, and is used to buffer and support the door.

[0062] The third support 331 refers to the support structure connected to the bracket frame 31, which can be implemented by welding metal plates or fixing with bolts to form a rigid support. The buffer wheel 332 refers to a wheel structure with an elastic material, which can be implemented by rubber wheels or polyurethane wheels. It buffers the impact force when the door 200 closes through rolling contact, and absorbs mechanical impact through elastic deformation during the closing process of the door 200. The cooperation between the buffer wheel and the third support achieves flexible buffering when the door closes, ensures precise control of the door opening and closing position during the test, and avoids damage to the exterior surface of the door 200 by sliding friction and rigid contact.

[0063] For example, the third support 331 can be designed as an H-shaped or U-shaped bent plate structure. Its two side plates with openings are used to clamp the buffer wheel 332 and are rotatably connected to the buffer wheel 332 via a rotating shaft. The buffer wheel 332 can be a polyurethane wheel supported by double-row ball bearings, with annular grooves on the wheel surface to increase the frictional contact area.

[0064] In some embodiments of the functionality, such as Figure 1 As shown, the support arm 32 can be a metal rod structure or an aluminum profile structure. The support arm 32 is approximately an L-shaped structure. One end of the support arm 32 is connected to the output end of the first drive mechanism 20, and the other end of the support arm 32 is connected to the bracket frame 31. The structure is simple and practical.

[0065] Reference Figure 2 The support frame 31 includes a first support rod 311, a second support rod 312, and a connector 313. Taking the first support rod 311 as a vertically extending rod-like structure and the second support rod 312 as a horizontally extending rod-like structure as an example, at least two first support rods 311 and at least two second support rods 312 are connected in an alternating manner by multiple connectors 313 to form a frame structure.

[0066] One end of the third support 331 is connected to either the first support rod 311 or the second support rod 312. The second drive mechanism 40 is connected and installed at different positions of the first support rod 311 and the second support rod 312, and its installation position can be adjusted along the length of the first support rod 311 and the second support rod 312 to adapt to door handles 201 in different positions.

[0067] For example, the first support rod 311 and the second support rod 312 can be metal rod structures or aluminum profile structures. If the first support rod 311 and the second support rod 312 are aluminum profile structures, they are lightweight and not easily rusted. The third support 331 and the second drive mechanism 40 can be flexibly adjusted in installation position through the guide groove of the aluminum profile.

[0068] To enable the second drive mechanism 40 to flexibly perform pressing and snapping actions, such as Figure 3As shown, the second drive mechanism 40 includes a hook 41, a first drive assembly 42, and a second drive assembly 43. The first drive assembly 42 is connected to the frame member 30, and the second drive assembly 43 is connected to at least the first drive assembly 42 and the hook 41. One of the first drive assembly 42 and the second drive assembly 43 is configured to drive the hook 41 to perform a pressing contact action, and the other of the first drive assembly 42 and the second drive assembly 43 is configured to drive the hook 41 to perform a latching and hooking action.

[0069] The hook 41 refers to an end-effector with a hook-like structure, which can be made of metal or high-strength composite material, and is used to directly contact the door handle 201 to perform pressing and hooking actions. The first drive assembly 42 refers to a power unit for generating linear or rotary motion, and its output end is connected to the second drive assembly 43 to drive the second drive assembly 43 and the hook 41 to perform linear or rotary motion. The second drive assembly 43 refers to a power unit with telescopic or rotary displacement, used to drive the hook 41 to perform telescopic or rotary displacement.

[0070] In this way, the first drive component 42 can drive the hook 41 to perform a snap-fit ​​action, and the second drive component 43 can drive the hook 41 to perform a pressing action. Alternatively, the second drive component 43 can drive the hook 41 to perform a snap-fit ​​action, and the first drive component 42 can drive the hook 41 to perform a pressing action. This is not limited, allowing for flexible configuration of the second drive mechanism 40.

[0071] The latching and pressing actions can be either linear movements of the hook 41 or rotational movements of the hook 41. The hook 41 can also be configured to perform the latching and pressing actions through linear and rotational movements, respectively.

[0072] For example, when the bracket frame 31 is in the first preset position, the first drive assembly 42 drives the second drive assembly 43 and the hook 41 to rotate as a whole through the hinge structure, so that the hook 41 approaches the door handle 201. At this time, if a pressing contact action is required, the linear drive component in the second drive assembly 43 can push the hook 41 to extend, so that its end contacts the button at the door handle 201 and applies pressure to perform the electric unlocking action. If a snap-on hooking action is required, the position of the hook 41 can be adjusted in advance by the second drive assembly 43 so that the first drive assembly 42 drives the hook 41 to rotate, so that its hook-shaped part is embedded in the door handle 201 structure. Then, the second drive assembly 43 retracts and drives the hook 41 to complete the hooking action to perform the mechanical unlocking action. The coordinated work of the two drive assemblies allows a single hook to complete different directional action combinations, which facilitates the flexible configuration of the second drive mechanism 40 and helps to improve the adaptability of the test decoration.

[0073] Thus, the outward-opening durability testing device 100 of this application can adapt to the testing needs of vehicle doors 200 with door handles 201 of different structural forms, especially for semi-concealed door handles that have both press-to-unlock and mechanical hook functions. The independent control of the two drive components avoids the need for equipment modification. By adjusting the sequence and amplitude of the drive components' movements, the testing requirements of different vehicle models can be matched, significantly improving the versatility and testing efficiency of the testing device.

[0074] For example, the second drive component 43 is used to drive the hook 41 to extend and retract in a straight line.

[0075] Linear telescopic movement refers to the hook 41 performing linear reciprocating motion in a single direction. Specifically, it can be achieved by using a linear motor or cylinder to drive the guide mechanism. The movement trajectory is limited by the guide hole to ensure the stability of the hook 41's movement direction.

[0076] In practical applications, the second drive assembly 43 outputs power through a linear drive component, driving the hook 41 to extend and retract linearly along the axial direction of the guide hole. When the switch button on the door handle 201 needs to be pressed, the hook 41 extends in a linear direction and contacts the button. When the door handle 201 needs to be hooked for mechanical unlocking, the second drive assembly 43 drives the hook 41, which is in a latched state, to retract in a linear direction, thereby unlocking and opening the door 200. When the door handle 201 needs to be hooked, the hook 41 maintains a suitable extended state, and the hooking angle can be adjusted by the first drive assembly 42 to complete the latching action. The linear motion trajectory can precisely control the displacement of the hook, ensuring the repeatability of the pressing or hooking action, and adapting to the testing needs of semi-concealed door handles of different sizes or shapes.

[0077] In some embodiments, such as Figure 2 and Figure 3As shown, the first drive assembly 42 includes a first linear drive member 421, a first support 422, and a second support 423. The first linear drive member 421 is connected to the frame member 30 (i.e., the bracket frame 31) via the first support 422. The second support 423 is connected to the frame member 30 (i.e., the bracket frame 31), and the second drive assembly 43 is hinged to the second support 423. The drive end of the first linear drive member 421 is hinged to the second drive assembly 43, and is used to drive the hook 41 to rotate and switch between a third preset position and a fourth preset position.

[0078] The first linear drive component 421 refers to a power device capable of outputting linear motion, which can be implemented by a cylinder or a linear motor. Its function is to drive the second drive component 43 to perform angle adjustment through linear reciprocating motion.

[0079] The first support 422 refers to the support structure used to fix the first linear drive component 421. Specifically, it can be implemented by a metal plate or a mounting base. Its function is to stably install the first linear drive component 421 at the first support rod 311 or the second support rod 312.

[0080] The second support 423 refers to the hinged structure used to support the second drive assembly 43. Specifically, it can be implemented using a connecting seat with a pin. By connecting the second support 423 to the first support rod 311 or the second support rod 312, a rotation fulcrum is provided for the second drive assembly 43. The hinge refers to a rotational connection method achieved through a pin or shaft. Its function is to allow the second drive assembly 43 to change its angle under the push of the first linear drive member 421 through rotational freedom, thereby driving the hook 41 to adjust its angle.

[0081] The first support 422 and the second support 423 are detachably connected to the bracket frame 31 so as to adapt to door handles at different heights by adjusting the installation position of the first support 422 and the second support 423 on the bracket frame 31.

[0082] For example, when the frame member 30 is in the first preset position, the first linear drive member 421 drives the second drive assembly 43 to rotate around the hinge point of the second support 423 through the linear motion of the drive end, thereby switching the hook 41 from the third preset position to the fourth preset position. During this process, the fixing effect of the first support 422 ensures the stability of the movement trajectory of the first linear drive member 421, and the hinge effect of the second support 423 converts the linear motion into a rotational action. The third preset position can be the state where the hook 41 is below the door handle 201, and the fourth preset position can be the position where the hook 41 is aligned with the unlock button of the door handle 201 after rotating a certain angle, or the fourth position can be used to engage and hook the door handle 201. Through the cooperation of the linear drive and the hinge structure, the hook 41 can accurately complete the alignment action of pressing contact or the hooking action.

[0083] Through the above technical solution, the linear drive mode can be converted into a rotational displacement mode with a suitable amplitude to meet the precise switching between the alignment action of the hook 41 in pressing contact or the hooking action, and can be adapted to semi-concealed door handles with different unlocking methods.

[0084] The second drive component 43 can be a linear drive structure or a rotary drive structure.

[0085] Taking the second drive component 43 as an example, which is a linear drive structure, continue to refer to... Figure 3 The second drive assembly 43 includes a rocker arm 431, a guide block 432, and a second linear drive member 433. The rocker arm 431 is hinged to the second support 423, and one end of the rocker arm 431 is hinged to the drive end of the first linear drive member 421. The other end of the rocker arm 431 is used to connect to the guide block 432, and the guide block 432 is provided with a guide hole. The second linear drive member 433 is connected to the rocker arm 431, and the drive end of the second linear drive member 433 is connected to the hook 41 through the guide hole, for driving the hook 41 to move axially and retract along the guide hole.

[0086] The rocker arm 431 is a rigid component that achieves lever transmission through a hinge fulcrum. It can be made of sheet metal or a rod. The rocker arm 431 swings around the hinge point due to the pushing and pulling action of the first linear drive 421, thus converting linear motion into rotational motion. The guide block 432 is a positioning component with a guide hole, which can be made of aluminum alloy or engineering plastic. Its guide hole constrains the movement trajectory of the hook 41, ensuring that the hook 41 extends or retracts along a preset linear path. The second linear drive 433 is a power element that outputs linear reciprocating motion. It can be implemented using a cylinder, linear motor, or electric actuator. Its drive end is rigidly connected to the hook 41 through the guide hole, directly controlling the extension or retraction of the hook 41.

[0087] For example, when a pressing action is required, the second linear drive 433 drives the hook 41 to extend axially along the guide hole, so that the front end of the hook 41 contacts the unlock button at the door handle 201. When a latching action is required, the first linear drive 421 pushes the rocker arm 431 to rotate around the hinge point, causing the guide block 432, the second linear drive 433, and the hook 41 to deflect by an overall angle to latch and hook the door handle 201. At this time, the second linear drive 433 can control the hook 41 to retract to hook the door handle 201 and unlock the door 200. By adjusting the hinge position and swing amplitude of the rocker arm 431, it can adapt to the different installation positions of door handles 201 of different sizes, while the axial constraint of the guide hole can ensure that the hook 41 does not shift during extension and retraction, thereby accurately pressing the unlock button to perform the electronic unlocking action.

[0088] Through the above technical solution, this application can integrate two motion modes in one drive mechanism, effectively solving the problem of incompatibility of test devices caused by the difference in unlocking method of semi-hidden door handles. At the same time, through modular design, the extension stroke and rotation angle of hook 41 are adjustable to meet the size change requirements of door handle 201 of different models, which significantly improves the versatility and testing efficiency of the test device.

[0089] Among them, such as Figure 3 As shown, the second drive assembly 43 also includes an extension rod 434. Along the axial direction of the guide hole, the guide block 432 and the rocker piece 431 are spaced apart and connected by the extension rod 434.

[0090] The extension rod 434 is a rigid connecting component that connects the guide block 432 and the rocker arm 431. It can be made of metal or plastic, and its length is determined based on the axial spacing requirements of the guide holes. The function of the extension rod 434 is to maintain the relative position between the guide block 432 and the rocker arm 431, preventing structural displacement due to external forces.

[0091] The extension rod 434 extends axially along the guide hole, fixing the guide block 432 and the rocker arm 431 together, maintaining a preset spatial distance between them. When the first linear drive 421 pushes the rocker arm 431 to rotate around the hinge point, the extension rod 434 can additionally increase the rotation trajectory radius at the hook 41. That is, the extension rod 434 allows for flexible control and adjustment of the rotation trajectory radius of the hook 41, ensuring that the operation of the door handle 201 during the test is consistent with the actual use scenario. It also enhances the adaptability of the device to door handles 201 of different sizes and installation positions, meeting the diverse testing needs of semi-concealed door handles.

[0092] The first linear drive unit 421 can be configured as a linear motor or a cylinder. The second linear drive unit 433 can also be configured as a linear motor or a cylinder.

[0093] A linear motor is a drive device that directly generates linear motion through electromagnetic action. Specifically, it can be implemented using a coreless linear motor or a flat linear motor. It features high-precision positioning and can accurately control the rotation angle and extension length of the hook 41. A cylinder is an actuator that uses compressed air to push a piston for linear motion. Specifically, it can be implemented using a double-acting cylinder or a rotary cylinder. It features rapid response and is suitable for pressing and contact scenarios requiring high-frequency actions. It has the advantages of simple structure and low cost. The combination of linear motors and cylinders can be flexibly configured according to actual testing needs. For example, linear motors are preferred for hooking and latching actions requiring high-precision positioning, while cylinders are preferred for pressing and contact actions requiring rapid reciprocating motion.

[0094] Alternatively, the first linear drive component 421 and the second linear drive component 433 can be set as cylinders, which have a simple structure and good stability and cost advantages.

[0095] Compared to existing technologies, traditional testing devices often employ servo motors in conjunction with linkage mechanisms to achieve compound motion, resulting in complex structures that struggle to accommodate different driving modes. In contrast, the modular combination design of linear motors and / or cylinders simplifies the spatial layout of the drive mechanism and, through the complementary characteristics of pneumatic and electric drives, reduces equipment maintenance costs while ensuring motion accuracy. For example, in high-temperature or low-temperature testing environments, cylinders exhibit superior resistance to temperature interference compared to traditional electric drive mechanisms.

[0096] Through the above technical solution, this application achieves accurate simulation of different unlocking actions of semi-concealed door handles, solving the problem that existing devices cannot meet the dual testing requirements of mechanical unlocking and electronic unlocking. The independent control characteristics of the linear motor and cylinder enable the device to quickly adjust the drive parameters according to the structural characteristics of door handles of different models. For example, by adjusting the cylinder stroke to adapt to the button pressing stroke of different depths, or by modifying the motion curve of the linear motor to match the hooking action of a specific angle.

[0097] like Figure 4 As shown, by setting the first drive mechanism 20 as a geared motor, the power unit can reduce the output speed and increase the torque. For example, a servo motor with a planetary gear reducer can be used, whose output shaft is connected to the bearing arm 32 through a coupling, thereby providing stable power for the rotational switching of the support frame 31 between the first preset position and the second preset position.

[0098] For example, the geared motor is mounted on the base 10 via a flange, and its output shaft is connected to the end of the support arm 32 via a keyway through a reduction gear set. When the geared motor starts, the output shaft drives the support arm 32 to rotate around its axis, thereby driving the bracket frame 31 to rotate and switch between a first preset position and a second preset position. When the bracket is in the first preset position, the buffer positioning member 33 contacts the door surface to form a support reference, and causes the hook 41 to engage and unlock the door handle 201. As the bracket frame 31 rotates to the second preset position, the door 200 is simultaneously fully opened.

[0099] Multiple rollers can be installed under the base 10 to facilitate flexible movement of the door outward opening durability testing device 100. A braking mechanism can be installed at the rollers to lock them in place, preventing the base 10 from shaking during the test.
