Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a door handle, a vehicle door and a vehicle. Background Art

[0002] At present, automobile door handles can be roughly divided into hidden handles and non-hidden handles according to their matching positions. Among them, the hidden inward-retracting door handle requires a space to accommodate the retraction of the handle. After the handle is retracted, another space that is completely independent of the retracted envelope of the handle is set. The relevant structure for opening the car door is set in this space. The human hand can operate the corresponding mechanism in this space to open the car door. That is, the hidden inward-retracting door handle solution requires two independent spaces, and the design solution must be made into an electric solution to drive the retraction of the handle, which makes the overall structure complex, costly, and heavy.

[0048] like Figure 1 、 Figure 2 and Figure 5 As shown, some embodiments of the present application provide a door handle, which is applied to a vehicle door to simplify the overall structure of the door handle, thereby reducing the production cost of the door handle.

[0049] The door handle includes a base 100, a handle 200, a first elastic member 300, an unlocking arm 400, a second elastic member 500, and a zipper 600. The first elastic member 300 and the second elastic member 500 can each be a spring or a torsion spring. Specifically, in this embodiment, the first elastic member 300 is a main torsion spring, and the second elastic member 500 is a torsion spring for the unlocking arm.

[0050] One side of the base 100 in the thickness direction defines a clearance groove 110. It should be noted that in this embodiment, the clearance groove 110 is a handle wrist body.

[0051] In addition, the handle 200 is rotatably connected to the base 100, that is, the handle 200 can rotate relative to the base 100. In this embodiment, the handle 200 is received in the clearance groove 110 and partially covers the notch of the clearance groove 110, that is, a portion of the clearance groove 110 is not covered by the handle 200, so that the user can pull the handle 200 through the clearance groove 110, thereby driving the handle 200 to rotate relative to the base 100.

[0052] Specifically, the side of the handle 200 facing away from the base 100 is flush with the notch of the clearance groove 110 to improve the aesthetics of the door handle.

[0053] In this embodiment, the handle 200 has a first state and a second state. The first state is the initial state of the handle 200, i.e., the state when the handle 200 is not subjected to external force. In this state, the handle 200 partially covers the notch of the clearance groove 110, and the side of the handle 200 facing away from the base 100 is flush with the notch of the clearance groove 110. The second state is the open state of the handle 200, i.e., the handle 200 rotates away from the base 100 under the action of external force. In this state, the handle 200 can open the vehicle door.

[0054] The first elastic member 300 is disposed on a side of the base 100 away from the handle 200. Specifically, the first elastic member 300 is disposed on a side of the base 100 away from the notch of the clearance groove 110. The first elastic member 300 is elastically connected to the handle 200 and exerts an elastic force on the handle 200, so that the handle 200 maintains the first state under the elastic force of the first elastic member 300.

[0055] In addition, when an external force acts on the handle 200, causing the handle 200 to rotate from the first state to the second state, the first elastic member 300 stores elastic potential energy to provide elastic resistance to the handle 200 through the first elastic member 300, and after the external force acting on the handle 200 is removed, the handle 200 is controlled to reset under the action of the elastic force of the first elastic member 300, that is, the handle 200 is controlled to return to the first state from the second state.

[0056] The unlocking arm 400 is rotatably arranged on a side of the base 100 away from the handle 200 , and the unlocking arm 400 is transmission-connected to the handle 200 so as to drive the unlocking arm 400 to rotate relative to the base 100 while the handle 200 rotates relative to the base 100 .

[0057] Specifically, the second elastic member 500 is elastically connected to the unlocking arm 400, and the second elastic member 500 exerts an elastic force on the unlocking arm 400, so that the unlocking arm 400 maintains its initial state. It should be noted that when the handle 200 is in the first state, the unlocking arm 400 abuts against the handle 200. At this time, the unlocking arm 400 is in the initial state, that is, the unlocking arm 400 and the handle 200 maintain a relatively stable state; when the handle 200 rotates from the first state to the second state, the handle 200 drives the unlocking arm 400 to rotate to a preset position. At the same time, the second elastic member 500 stores elastic potential energy and exerts an elastic resistance on the unlocking arm 400, so that the unlocking arm 400 can return to its initial state under the elastic resistance of the second elastic member 500. In addition, when the handle 200 is restored from the second state to the first state, that is, the force exerted by the handle 200 on the unlocking arm 400 is cancelled, the unlocking arm 400 rotates to the initial state under the elastic force of the second elastic member 500, so as to control the reset of the unlocking arm 400 through the second elastic member 500.

[0058] In this embodiment, the initial state of the unlocking arm 400 refers to the state of the unlocking arm 400 relative to the handle 200 when the handle 200 is in the first state. At this time, the unlocking arm 400 abuts against the handle 200 and is in a relatively static state with the handle 200.

[0059] In addition, the zipper 600 is arranged on the side of the base 100 away from the handle 200, and one end of the zipper 600 is connected to the unlocking arm 400 so that the zipper 600 can be pulled while the unlocking arm 400 rotates relative to the base 100. In this embodiment, the other end of the zipper 600 is used to be connected to the door lock mechanism of the vehicle door so that the zipper 600 can be pulled by the unlocking arm 400 while the door lock mechanism of the vehicle door is pulled by the zipper 600, thereby unlocking the vehicle door.

[0060] Specifically, when the handle 200 rotates from the first state to the second state under the action of an external force, the handle 200 drives the unlocking arm 400 to rotate synchronously, and the unlocking arm 400 rotates while pulling the zipper 600, which pulls the door lock mechanism of the vehicle door, thereby unlocking the vehicle door. When the external force acting on the handle 200 is removed, the handle 200 returns to the first state from the second state under the elastic force of the first elastic member 300. During this process, the unlocking arm 400 is driven by the second elastic member 500 to return to its original state, and the unlocking arm 400 pulls the zipper 600 to return to its original state, so that the vehicle door can be unlocked again through the zipper 600.

[0061] The first elastic member 300 provides elastic resistance to the handle 200, so that the handle 200 can rotate from the first state to the second state under the action of an external force. The handle 200 drives the unlocking arm 400 to rotate synchronously, and the unlocking arm 400 pulls the zipper 600, so that the door lock mechanism of the vehicle door is pulled through the zipper 600, thereby unlocking the vehicle door. When the external force acting on the handle 200 is removed, the handle 200 can be restored from the second state to the first state under the elastic force of the first elastic member 300, and the unlocking arm 400 can be restored to the initial state under the elastic force of the second elastic member 500. The unlocking arm 400 drives the zipper 600 to be restored to the initial state, so that the vehicle door can be unlocked again. This application simplifies the overall structure of the door handle, which not only improves the production efficiency of the door handle, but also reduces the production cost of the door handle.

[0062] like Figure 5 As shown, in some embodiments of the present application, the handle 200 includes a body 210, a first driving arm 220 and a second driving arm 230, and the first driving arm 220 and the second driving arm 230 are arranged at intervals on a side of the body 210 facing the base 100.

[0063] In addition, the handle 200 also includes a handle cover 250, which is arranged on the side of the main body 210 away from the first driving arm 220 and the second driving arm 230, and the connection method between the handle cover 250 and the main body 210 includes any one of bonding, snap connection or one-piece molding.

[0064] Specifically, in this embodiment, the handle cover 250 is mounted on the body 210 via internal snaps, that is, the handle cover 250 and the body 210 are snap-connected.

[0065] Specifically, one end of the first driving arm 220 and the second driving arm 230 is connected to the main body 210, and the first driving arm 220 and the second driving arm 230 are respectively passed through the base 100 at one end away from the main body 210, and are rotatably connected to the side of the base 100 away from the main body 210.

[0066] In this embodiment, the first driving arm 220 and the second driving arm 230 are respectively "L"-shaped structures to improve the smoothness and stability of the handle 200 during rotation relative to the base 100 and avoid collision between the handle 200 and the base 100.

[0067] It should be noted that a clearance space is provided on the side of the body 210 away from the first driving arm 220 and the second driving arm 230 , so that the user's hand can be inserted into the clearance space through the clearance groove 110 to facilitate turning the handle 200 .

[0068] Among them, a convex portion 240 is provided on the side of the first driving arm 220 facing the second driving arm 230, so that the convex portion 240 abuts against the unlocking arm 400, so that when the handle 200 rotates under the action of external force, the unlocking arm 400 is pushed to rotate synchronously through the convex portion 240.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the base 100 is provided with a first mounting hole 120 and a second mounting hole 130 that are oppositely arranged on the side facing away from the main body 210, wherein the aperture of the first mounting hole 120 is equal to the aperture of the second mounting hole 130, the axis of the first mounting hole 120 coincides with the axis of the second mounting hole 130, and the first mounting hole 120 and the second mounting hole 130 are both blind holes.

[0070] like Figure 2 and Figure 5 As shown, in some embodiments of the present application, the first elastic member 300 includes a first torsion spring 310, a support rod 320, and a sleeve 330. It should be noted that, in this embodiment, the first torsion spring 310 is a main torsion spring, the support rod 320 is a main pin, and the sleeve 330 is a through pin.

[0071] One end of the support rod 320 passes through the end of the first driving arm 220 away from the body 210 and is inserted into the first mounting hole 120. It is understandable that the axis of the support rod 320 coincides with the axis of the first mounting hole 120.

[0072] In this embodiment, one end of the support rod 320 close to the first driving arm 220 abuts against the inner wall of the first mounting hole 120 to enhance the stability of the connection between the support rod 320 and the hole wall of the first mounting hole 120 .

[0073] In addition, the end of the support rod 320 facing away from the first driving arm 220 is passed through the end of the second driving arm 230 facing away from the main body 210, and is inserted into the second mounting hole 130. It can be understood that the axis of the support rod 320 coincides with the axis of the second mounting hole 130.

[0074] In this embodiment, one end of the second connecting rod 420 close to the second driving arm 230 abuts against the inner wall of the second mounting hole 130 to improve the stability of the connection between the second connecting rod 420 and the hole wall of the second mounting hole 130, so as to form a limiting effect on the support rod 320 through the first mounting hole 120 and the second mounting hole 130, so as to improve the stability of the connection between the support rod 320 and the base 100.

[0075] Furthermore, the shaft sleeve 330 is sleeved on the support rod 320 and disposed between the first driving arm 220 and the second driving arm 230. The shaft sleeve 330 is limited by the first driving arm 220 and the second driving arm 230, thereby improving the stability of the shaft sleeve 330 between the first driving arm 220 and the second driving arm 230. The shaft sleeve 330 is rotatably connected to the support rod 320, so that the shaft sleeve 330 can rotate relative to the support rod 320.

[0076] In addition, the first torsion spring 310 is sleeved on the shaft sleeve 330. It should be noted that the first torsion spring 310 includes a first torsion spring arm 311 and a second torsion spring arm 312, wherein the elastic forces of the first torsion spring arm 311 and the second torsion spring arm 312 are opposite. For example, if the elastic force of the first torsion spring arm 311 acts in a clockwise direction, the elastic force of the second torsion spring arm 312 acts in a counterclockwise direction; if the elastic force of the first torsion spring arm 311 acts in a counterclockwise direction, the elastic force of the second torsion spring arm 312 acts in a clockwise direction.

[0077] Specifically, the first torsion spring arm 311 abuts against the base 100, and the second torsion spring arm 312 abuts against the first driving arm 220 and the second driving arm 230, so that the second torsion spring arm 312 provides elastic resistance to the first driving arm 220 and the second driving arm 230, thereby ensuring that the handle 200 can be stably in the first state.

[0078] When the handle 200 rotates from the first state to the second state under the action of external force, the first driving arm 220 and the second driving arm 230 respectively squeeze the second torsion spring arm 312, and make the second torsion spring arm 312 bend and store elastic potential energy, so that the second torsion spring arm 312 applies elastic force to the first driving arm 220 and the second driving arm 230, and after the external force acting on the handle 200 is removed, the first driving arm 220 and the second driving arm 230 respectively restore their initial states under the elastic force of the second torsion spring arm 312, thereby driving the handle 200 to rotate from the second state to the first state, thereby ensuring the stability of the handle 200 in the first state.

[0079] In addition, in some embodiments, a convex rib 140 is provided on the side of the base 100 facing the first elastic member 300, and there is a gap between the convex rib 140 and the shaft sleeve 330, and the first torsion spring arm 311 is sleeved on the convex rib 140, so that the convex rib 140 forms a limiting effect on the first torsion spring arm 311, thereby improving the stability of the first torsion spring 310 between the first driving arm 220 and the second driving arm 230, and improving the stability of the connection between the first elastic member 300 and the base 100.

[0080] like Figure 6 and Figure 7As shown, in some embodiments of the present application, the unlocking arm 400 includes a connecting block 410 and a connecting rod 420 .

[0081] The connection method between the connecting block 410 and the connecting rod 420 includes at least one of threaded connection, bolt connection, clamping, bonding, and integral molding, which can be specifically set according to actual conditions.

[0082] In this embodiment, the connecting block 410 and the connecting rod 420 are integrally formed and connected to improve the strength and stability of the overall structure of the unlocking arm 400.

[0083] Specifically, the connecting rod 420 is provided at one end of the connecting block 410 , the axial direction of the connecting rod 420 is parallel to the thickness direction of the connecting block 410 , and the connecting rod 420 is rotatably connected to the base 100 .

[0084] It can be understood that the connecting block 410 rotates around the axis of the connecting rod 420 .

[0085] In addition, a curved burr 411 is provided on the side of the connecting block 410 facing the first driving arm 220. The curved burr 411 is smoothly connected to the connecting block 410, so that the unlocking arm 400 can be driven to rotate smoothly during the rotation of the handle 200 relative to the base 100, thereby improving the smoothness of the rotation of the unlocking arm 400 relative to the base 100 and the smoothness of the synchronous rotation of the unlocking arm 400 relative to the handle 200. Since the unlocking arm 400 is used to connect to the door lock mechanism of the vehicle door, the smoothness of the movement of the door lock mechanism is improved, thereby ensuring smooth door opening.

[0086] In this embodiment, a slot 413 is provided on the side of the connecting block 410 away from the arc-shaped burr 411. The slot 413 is arranged at the end of the connecting block 410 away from the connecting rod 420. The notch of the slot 413 faces the second driving arm 230, and a guide notch 414 is provided on the side of the slot 413 away from the connecting rod 420. The guide notch 414 is an "L"-shaped notch.

[0087] like Figures 2 to 4 As shown, in some embodiments, a clamping portion 150 is provided on the side of the base 100 facing away from the main body 210, and the zipper 600 is clamped on the clamping portion 150 to provide a limiting and fixing function for the zipper 600 through the clamping portion 150, so as to improve the stability of the connection between the zipper 600 and the base 100.

[0088] Among them, one end of the zipper 600 is accommodated in the card slot 413, and the other end of the zipper 600 is passed through the guide notch 414, so that the zipper 600 is limited by the card slot 413 and the guide notch 414 to improve the stability of the connection between the zipper 600 and the connecting block 410.

[0089] It should be noted that, by providing a guide notch 414 on one side of the slot 413 , the efficiency of connecting or disassembling the zipper 600 and the connecting block 410 is improved, so as to facilitate maintenance or replacement.

[0090] like Figures 5 to 7 As shown, in some embodiments of the present application, the arc-shaped burr 411 has a convex surface and a concave surface, and the protrusion 240 is slidingly connected to the convex surface of the arc-shaped burr 411, that is, the side wall of the protrusion 240 abuts against the convex surface of the arc-shaped burr 411, and the side wall of the protrusion 240 is slidingly connected to the convex surface of the arc-shaped burr 411, so that during the rotation of the handle 200 relative to the base 100, the protrusion 240 can be driven to rotate by the first driving arm 220, and the protrusion 240 abuts against the arc-shaped burr 411 and pushes the arc-shaped burr 411 to rotate. Since the protrusion 240 is slidingly connected to the convex surface of the arc-shaped burr 411, that is, the protrusion 240 can slide along the arc-shaped burr 411, so as to improve the smoothness and fluidity of the unlocking arm 400 relative to the rotation of the base 100.

[0091] Furthermore, there is a gap between the side of the protrusion 240 facing the unlocking arm 400 and the unlocking arm 400 to avoid friction between the protrusion 240 and the side of the unlocking arm 400 facing the protrusion 240 during the rotation relative to the unlocking arm 400, thereby improving the smoothness of the rotation of the unlocking arm 400.

[0092] In addition, a stopper 412 is provided at the end of the arc-shaped burr 411 facing away from the connecting rod 420. The stopper 412 limits the handle 200 to prevent the handle 200 from being disengaged from the unlocking arm 400, thereby ensuring the stability of the connection between the handle 200 and the unlocking arm 400. Specifically, the stopper 412 limits the protrusion 240 to prevent the handle 200 from being disengaged from the unlocking arm 400, thereby ensuring the stability of the sliding connection between the unlocking arm 400 and the handle 200 and improving the rotational stability of the unlocking arm 400 and the handle 200.

[0093] like Figure 2 and Figure 5 As shown, in some embodiments of the present application, the second elastic member 500 is sleeved on the connecting rod 420 .

[0094] Among them, the second elastic member 500 includes a third torsion spring arm 510 and a fourth torsion spring arm 520, the third torsion spring arm 510 abuts against the base 100, and the fourth torsion spring arm 520 abuts against the connecting block 410, so as to provide an elastic limiting effect on the connecting block 410 through the second elastic member 500, so as to ensure that the connecting block 410 can restore to its initial state under the elastic force of the second elastic member 500.

[0095] Specifically, when the handle 200 rotates from the first state to the second state under the action of external force, the unlocking arm 400 rotates to a preset position under the push of the handle 200. At this time, the fourth torsion spring arm 520 bends under the pressure of the connecting block 410 and stores elastic potential energy; when the handle 200 rotates from the second state to the first state, the external force acting on the unlocking arm 400 is cancelled, so that the unlocking arm 400 returns to its initial state under the elastic force of the fourth torsion spring arm 520, thereby making the unlocking arm 400 abut against the first driving arm 220 to ensure that the handle 200 can push the unlocking arm 400 to rotate synchronously.

[0096] Some embodiments of the present application also provide a vehicle door, comprising the door handle described in any one of the above embodiments.
