Abstract
Description
Technical Field
[0001] This utility model relates to a vehicle lock component, and more particularly to a door handle, a car door, and a vehicle. Background Technology
[0002] With the continuous development of electronic technology, more and more electronic technologies are being applied to automobiles, making their functions increasingly rich. Currently, some cars use concealed door handles. Concealed handles are not only neat and aesthetically pleasing, making the door appear smoother and flatter, but they also reduce wind resistance and noise during driving. However, due to internal space limitations, current concealed door handles mainly rely on a single drive source to move the handle. When the handle is fully retracted into the door, a spring or other elastic component is usually needed to maintain its position. But for multi-stage handles, a single elastic component cannot provide stable restoring force throughout the handle's multiple strokes, resulting in the handle not fully retracting into the door. Therefore, there is an urgent need for a door handle that can control the movement of the handle more stably. Utility Model Content
[0003] The purpose of this utility model is to provide a door handle, a car door, and a vehicle to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The solution to the technical problem of this utility model is:
[0005] A door handle includes: a housing with an opening on one side; a rotating block rotatably connected to the housing, the rotating block having a guide groove, one end of the guide groove being a starting end and the other end being an ending end, the ending end being inclined in a direction close to the opening; a handle movably connected to the housing, a driven arm rotatably connected to the side of the handle away from the opening, a driven shaft connected to the driven arm, the driven shaft extending into the guide groove; a first elastic element disposed between the driven shaft and the rotating block, the first elastic element having a tendency to move the driven shaft to the starting end; and a second elastic element disposed between the rotating block and the housing, the second elastic element having a tendency to allow the handle to enter the opening.
[0006] This technical solution has at least the following beneficial effects: The handle and driven arm are connected to the transmission assembly of the peripheral device, which provides power to the handle and driven arm. Initially, the handle is located inside the housing, and the driven shaft is at the beginning of the guide groove. When the handle and driven arm are subjected to external force, the driven shaft on the driven arm moves along the guide groove. Since the end of the guide groove is inclined towards the opening, when the driven shaft reaches the end, the driven shaft and the handle as a whole move horizontally out of the housing from the opening. During this process, the elastic force of the first elastic element is mainly overcome. As force continues to be applied to the handle and driven arm, the rotating block can be driven to rotate, causing the handle to rotate further out of the housing to form a larger opening. During the process, since the first elastic element also rotates along with the rotating block, it mainly overcomes the elastic force of the second elastic element. When the handle needs to enter the opening, the handle and driven arm are driven by external force to rotate and reset first. At this time, the restoring elastic force of the second elastic element can drive the rotating block to rotate, thereby ensuring that the handle can move into place in this stroke. Then the handle is moved horizontally into the housing. At this time, the driven shaft moves from the end to the beginning. The restoring elastic force of the first elastic element can assist the driven shaft to move, thereby ensuring that the handle can be fully reset. In this way, the first elastic element and the second elastic element provide reset force in different stroke paths of the handle, which is conducive to the stable return of the handle to the reset. Moreover, the overall structure is simple and highly practical.
[0007] As a further improvement to the above technical solution, the first elastic element is a first torsion spring, one arm of the first torsion spring is connected to the driven shaft, and the other arm of the first torsion spring is connected to the rotating block.
[0008] As a further improvement to the above technical solution, a first arc-shaped rib is provided on the side of the rotating block near the handle, and the spring coil of the first torsion spring is located inside the first arc-shaped rib.
[0009] As a further improvement to the above technical solution, the second elastic element is a second torsion spring, one arm of the second torsion spring is connected to the rotating block, and the other arm of the second torsion spring is connected to the outer shell.
[0010] As a further improvement to the above technical solution, a second arc-shaped rib is provided on the side of the rotating block away from the handle, and the spring coil of the desired second torsion spring is located inside the second arc-shaped rib.
[0011] As a further improvement to the above technical solution, the torque of the second torsion spring is greater than that of the first torsion spring.
[0012] As a further improvement to the above technical solution, the rotating block is located on the outside of the housing, and the housing is provided with a clearance groove corresponding to the position of the guide groove. The driven arm passes through the clearance groove and extends into the guide groove, and the length of the clearance groove is greater than the length of the guide groove.
[0013] As a further improvement to the above technical solution, the outer shell is provided with an anti-collision pad, and when the driven shaft is located at the starting end, the rotating block abuts against the anti-collision pad.
[0014] A vehicle door includes a door panel, the aforementioned door handle, and the housing is connected within the door panel.
[0015] A vehicle that includes the aforementioned door.

[0026] Reference Figures 1 to 3 A door handle includes a housing 100, a rotating block 200, a handle 300, a first elastic element 400, and a second elastic element 500. The housing 100 has an opening on one side. The rotating block 200 is rotatably connected to the housing 100 and has a guide groove 210. One end of the guide groove 210 is a starting end, and the other end is an ending end. The ending end is inclined towards the opening. In practical applications, the guide groove 210 may be inclined only near the ending end towards the opening, or it may be inclined entirely towards the opening. The handle 300 is movably connected to the housing. Within 100, a driven arm 310 is rotatably connected to the side of the handle 300 away from the opening. The rotation axis of the driven arm 310 extends horizontally, and a driven shaft 311 is connected to the driven arm 310, extending into the guide groove 210. A first elastic member 400 is disposed between the driven shaft 311 and the rotating block 200, and the first elastic member 400 has a tendency to move the driven shaft 311 to the beginning end. A second elastic member 500 is disposed between the rotating block 200 and the outer casing 100, and the second elastic member 500 has a tendency to cause the handle 300 to enter the opening.
[0027] As described above, the handle 300 and driven arm 310 are connected to the transmission assembly of the peripheral device. The transmission assembly of the peripheral device provides power to the handle 300 and driven arm 310. In the initial state, the handle 300 is located inside the housing 100, and the driven shaft 311 is located at the beginning of the guide groove 210. When the handle 300 and driven arm 310 are subjected to external force, the driven shaft 311 on the driven arm 310 moves along the guide groove 210. Since the end of the guide groove 210 is inclined in the direction close to the opening, when the driven shaft 311 moves to the end, the driven shaft 311 and the handle 300 as a whole move out of the housing 100 from the opening. In this process, the elastic force of the first elastic element 400 is mainly overcome. As force continues to be applied to the handle 300 and driven arm 310, the rotating block 200 can be driven to rotate, so that the handle 300 can be further rotated out of the housing 100 to form a larger opening. During this process, since the first elastic element 400 also rotates along with the rotating block 200, it mainly overcomes the elastic force of the second elastic element 500. When the handle 300 needs to enter the opening, the handle 300 and the driven arm 310 are driven by external force to rotate and reset first. At this time, the restoring elastic force of the second elastic element 500 can drive the rotating block 200 to rotate, thereby ensuring that the handle 300 can move into place during this stroke. Then, the handle 300 is moved into the housing 100. At this time, the driven shaft 311 moves from the end to the beginning. The restoring elastic force of the first elastic element 400 can assist the driven shaft 311 to move, thereby ensuring that the handle 300 can be fully reset. In this way, the first elastic element 400 and the second elastic element 500 provide reset force in different stroke paths of the handle 300, which is conducive to the stable return of the handle 300 to the reset position. Moreover, the overall structure is simple and highly practical.
[0028] Naturally, the housing 100 is equipped with a transmission component that can drive the handle 300 to move, thereby providing a driving force for the handle 300 to enter and exit the opening. Specifically, the transmission component includes a drive source, a first transmission arm and a second transmission arm. The drive source has a drive end that can reciprocate in a linear direction. The drive source can be an electric screw, a cylinder or a hydraulic cylinder, etc. One end of the first transmission arm is rotatably connected to the drive end along a horizontal axis. One end of the driven arm 310 is rotatably connected to one side of the handle 300. The other end of the driven arm 310 is rotatably connected to the other end of the first transmission arm along a horizontal axis. One end of the second transmission arm is rotatably connected to the middle of the first transmission arm along a horizontal axis. The other end of the second transmission arm is rotatably connected to the other side of the handle 300 along a horizontal axis. During operation, the drive source pushes out the first transmission arm, which in turn drives the driven shaft 311 on the driven arm 310 to move from the beginning to the end of the guide groove 210. The handle 300 moves out of the housing 100 from the opening. As the drive source continues to push the first transmission arm, the handle 300 rotates with the driven arm 310 and the second transmission arm as the pivot points, thereby further opening to increase the opening degree of the extension from the housing 100.
[0029] The first elastic element 400 is mainly used to provide elastic force to the driven shaft 311, thereby causing the driven shaft 311 to tend to move to the end of the guide groove 210. The first elastic element 400 can have various structural forms, such as springs, rubber, etc. In this embodiment, the first elastic element 400 is a first torsion spring. One arm of the first torsion spring is connected to the driven shaft 311, and the other arm of the first torsion spring is connected to the rotating block 200. The rotating block 200 may be provided with a structure for clamping and fixing the arm of the first torsion spring, thereby positioning one arm of the first torsion spring relatively on the rotating block 200, while the other arm of the first torsion spring can form a hook, which is hooked on the outside of the driven shaft 311, thereby positioning the other arm of the first torsion spring relatively. When the driven shaft 311 is moved by an external force, it drives the arm of the first torsion spring to move at the same time, thus overcoming the torque of the first torsion spring. When the external force on the driven shaft 311 is removed, the first torsion spring provides torque to make the driven shaft 311 return to its original position.
[0030] To facilitate the positioning of the first torsion spring on the rotating block 200, in this embodiment, the rotating block 200 is provided with a first arc-shaped rib 220 on the side near the handle 300, and the spring coil of the first torsion spring is located within the first arc-shaped rib 220. The first arc-shaped rib 220 extends arc-shaped on the rotating block 200, forming an area for accommodating the first torsion spring. When installing the first torsion spring, the spring coil portion of the first torsion spring can be directly inserted into this area. At this time, the lever arm of the first torsion spring can extend from the part outside the first arc-shaped rib 220, and the first arc-shaped rib 220 will not interfere with the movement of the lever arm.
[0031] The second elastic element 500 mainly provides elastic force for the reset of the rotating block 200. Its structural form can vary, such as a spring or rubber. In this embodiment, the second elastic element 500 is a second torsion spring. One arm of the second torsion spring is connected to the rotating block 200, and the other arm is connected to the outer casing 100. The rotating block 200 and the outer casing 100 are provided with structures that can lock the arm of the second torsion spring. When the rotating block 200 is rotated by an external force, it drives one arm of the second torsion spring to rotate simultaneously, thus overcoming the torque of the second torsion spring. When the external force on the rotation of the rotating block 200 is removed, the second torsion spring provides torque to cause the rotating block 200 to return to its reset position.
[0032] To facilitate the positioning of the second torsion spring on the rotating block 200, in this embodiment, a second arc-shaped rib 230 is provided on the side of the rotating block 200 away from the handle 300, and the coil of the second torsion spring is located within the second arc-shaped rib 230. The second arc-shaped rib 230 extends arc-shaped on the other side of the rotating block 200, forming an area for accommodating the second torsion spring. When installing the second torsion spring, the coil portion of the second torsion spring can be directly inserted into this area. At this time, the lever arm of the second torsion spring can extend from the part outside the second arc-shaped rib 230, and the second arc-shaped rib 230 will not interfere with the movement of the lever arm.
[0033] To better provide restorative force segmentally from the first torsion spring and the second torsion spring, in this embodiment, the torque of the second torsion spring is greater than that of the first torsion spring. When the driven shaft 311 moves from the beginning to the end of the guide groove 210, because the torque of the second torsion spring is greater than that of the first torsion spring, the driven shaft 311 overcomes the torque of the first torsion spring and moves along the guide groove 210, making it difficult for the rotating block 200 to be driven to rotate. When the driven shaft 311 moves to the end of the guide groove 210, it is necessary to overcome the torque of the second torsion spring to make the rotating block 200 rotate. This is beneficial for the first torsion spring and the second torsion spring to provide restorative force in different stroke paths of the handle 300.
[0034] The rotating block 200 can be disposed on the outer side or the inner side of the housing 100. In order to reduce the occupation of the internal space of the housing 100, in this embodiment, the rotating block 200 is located on the outer side of the housing 100. The housing 100 is provided with a clearance groove corresponding to the position of the guide groove 210. The driven arm 310 passes through the clearance groove and extends into the guide groove 210. The length of the clearance groove is greater than the length of the guide groove 210. The clearance groove itself can further stabilize the driven shaft 311. When the driven shaft 311 moves from the beginning to the end along the guide groove 210, and when the driven shaft 311 drives the rotating block 200 to rotate, since the length of the clearance groove is greater than the length of the guide groove 210, the driven shaft 311 always moves along the clearance groove and will not interfere with the housing 100 itself, thereby improving the stability of the movement of the driven shaft 311.
[0035] To provide elastic cushioning for the driven shaft 311 as it moves to the end of the guide groove 210, in this embodiment, a shock absorber 600 is provided on the housing 100. When the driven shaft 311 is at the beginning, the rotating block 200 abuts against the shock absorber 600. When the first elastic member 400 provides elastic force to the driven shaft 311, causing the driven shaft 311 to move to the end position, the rotating block 200 abuts against the shock absorber 600, reducing the impact of the driven shaft 311 on the end position of the guide groove 210, thereby reducing noise and improving the overall structural stability of operation.
[0036] A vehicle door includes a door panel, the aforementioned door handle, and the housing 100 connected within the door panel.
[0037] In this car door, due to the aforementioned door handle, the first elastic element 400 and the second elastic element 500 can respectively provide a restoring force in different stroke paths of the handle 300, which is conducive to the stable return of the handle 300 to its reset position. Furthermore, the overall structure is simple and highly practical.
[0038] A vehicle includes the aforementioned door, wherein the aforementioned door handle is provided on the door, thereby improving the stability and service life of the handle 300 when it is moved out of or retracted from the housing 100.
[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
