Description

Technical Field

[0001] The present invention relates to the technical field of vehicle accessories, and particularly to a damping buffer door handle and a vehicle. Background Art

[0002] Automobile door handles generally include a base body and a handle. One end of the handle is connected to a rotating shaft, and a torsion spring is arranged on the rotating shaft. One end of the handle is rotatably connected to the base body. Pulling the other end of the handle can open the door. After releasing the hand, under the action of the torsion spring, the handle can be rotated back to its original position.

[0003] In related technologies, some door handles lack a damping buffer structure, resulting in excessive rebound noise. Although some door handles are provided with a damping buffer structure, they have the defect of poor user experience. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a damping buffer door handle, which can provide damping buffer for the rebound of the handle and can improve the user experience.

[0005] The present invention also provides a vehicle.

[0006] The damping buffer door handle according to the first aspect embodiment of the present invention includes: a base having an open accommodation space, and a sliding groove is provided on the side wall of the accommodation space; a torsion spring arranged in the accommodation space; a handle, one end of which is rotatably connected to the base to enter and exit the accommodation space, and the torsion spring is connected to the handle and the base for driving the handle to rotate back to the inside of the accommodation space; an abutting block is elastically connected to the side of the handle, and the abutting block abuts against the bottom wall of the sliding groove, and the distance between the bottom wall of the sliding groove and the side of the handle gradually increases from inside to outside.

[0007] The damping buffer door handle according to the embodiments of the present invention has at least the following beneficial effects: The base can be installed on the car door. The base has an open accommodating space, and a chute is provided on the side wall of the accommodating space. One end of the handle is rotatably connected to the base. By rotating the handle outward or inward, the handle can enter and exit the accommodating space. Appropriately, a contact block is elastically connected to the side of the handle. The contact block abuts against the bottom wall of the chute, and the distance between the bottom wall of the chute and the side of the handle gradually increases from inside to outside. When the user pulls the handle to rotate outward against the torsion of the torsion spring, through the elastic connection between the side of the handle and the contact block, the contact block remains in contact with the bottom wall of the chute, thereby providing a certain damping. Since the distance between the bottom wall of the chute and the side of the handle gradually increases from inside to outside, as the handle rotates outward gradually, the pressure exerted by the contact block on the bottom wall of the chute gradually decreases, that is, the damping of the handle rotating outward gradually decreases, so as to facilitate the user to rotate the handle outward. The torsion spring is connected to the handle and the base, and is used to drive the handle to rotate and reset inward into the accommodating space. When the user releases the pulling force on the handle, under the action of the torsion spring, the handle rotates and resets inward into the accommodating space. Since the distance between the bottom wall of the chute and the side of the handle gradually decreases from outside to inside, as the handle rotates inward gradually, the pressure exerted by the contact block on the bottom wall of the chute gradually increases, that is, the damping of the handle rotating inward gradually increases, which can effectively buffer the impact force of the handle rotating inward and reduce the noise generated by the rebound. That is, the damping buffer door handle improves the user experience through the gradually decreasing damping force of the handle rotating outward and the gradually increasing damping force of the handle rotating inward.

[0008] According to some embodiments of the present invention, the damping buffer door handle further includes a compression elastic member. A clamping groove opposite to the chute is provided on the side wall of the handle. The compression elastic member is arranged in the clamping groove, and two ends of the compression elastic member respectively abut against the bottom wall of the clamping groove and one end of the contact block, so as to drive the other end of the contact block to abut against the bottom wall of the chute.

[0009] According to some embodiments of the present invention, the compression elastic member is a spring. A positioning post extending towards the chute is provided on the bottom wall of the clamping groove, and the spring is sleeved on the positioning post.

[0010] According to some embodiments of the present invention, the upper end of the handle is rotatably connected to the base. A concave grip groove is provided on the lower end of the handle. The contact block is connected to the left or right side of the handle; when the handle is embedded in the accommodating space, a distance is left between the lower end of the handle and the lower wall surface of the accommodating space.

[0011] According to some embodiments of the present invention, the handle includes a housing and a rotating arm. The grip groove is arranged on the housing. The rotating arm includes a first sub-bar and a second sub-bar arranged at an angle. The upper end of the first sub-bar is rotatably connected to the base. The lower end of the first sub-bar inclines inward and is fixedly connected to the upper end of the second sub-bar. The lower end of the second sub-bar is fixedly connected to the housing.

[0012] According to some embodiments of the present invention, the card slot is provided at the junction of the first sub-bar and the second sub-bar.

[0013] According to some embodiments of the present invention, the damped buffer door handle further includes a rotating shaft connected to the base. There are two rotating arms. Perforations are respectively provided at the upper ends of the two rotating arms. The two ends of the rotating shaft are respectively inserted into the two perforations, and a torsion spring is sleeved on the rotating shaft.

[0014] According to some embodiments of the present invention, the accommodating space includes a through hole, an inner cavity and an outer cavity. The inner cavity opens inward, the outer cavity opens outward, the two ends of the through hole are respectively communicated with the inner cavity and the outer cavity. The handle is inserted through the through hole. One end of the handle is rotatably connected to the base and is arranged in the inner cavity. The handle can abut against the two opposite side walls of the through hole, so that the other end of the handle can enter and exit the outer cavity.

[0015] According to some embodiments of the present invention, the damped buffer door handle has a closed state, and the closed state is that the handle is embedded in the accommodating space, and the outer end surface of the handle is flush with the outer end surface of the base.

[0016] The vehicle according to the second aspect embodiment of the present invention includes the damped buffer door handle shown in any item of the first aspect.

[0017] The vehicle according to the embodiment of the present invention has at least the following beneficial effects: The vehicle includes the damped buffer door handle shown in any item of the first aspect. The base can be installed on the car door. The base has an open accommodating space, and a chute is provided on the side wall of the accommodating space. One end of the handle is rotatably connected to the base. By rotating the handle outward or inward, the handle can enter and exit the accommodating space. Appropriately, an abutting block is elastically connected to the side of the handle. The abutting block abuts against the bottom wall of the chute, and the distance between the bottom wall of the chute and the side of the handle gradually increases from inside to outside. When the user pulls the handle to rotate outward against the torsion force of the torsion spring, through the elastic connection between the side of the handle and the abutting block, the abutting block remains in contact with the bottom wall of the chute, thereby providing a certain damping. Since the distance between the bottom wall of the chute and the side of the handle gradually increases from inside to outside, as the handle gradually rotates outward, the pressure exerted by the abutting block on the bottom wall of the chute gradually decreases, that is, the damping of the handle rotating outward gradually decreases, so as to facilitate the user to rotate the handle outward. The torsion spring is connected to the handle and the base, and is used to drive the handle to rotate and reset inward into the accommodating space. When the user releases the pulling force on the handle, under the action of the torsion spring, the handle rotates and resets inward into the accommodating space. Since the distance between the bottom wall of the chute and the side of the handle gradually decreases from outside to inside, as the handle gradually rotates inward, the pressure exerted by the abutting block on the bottom wall of the chute gradually increases, that is, the damping of the handle rotating inward gradually increases, which can effectively buffer the impact force of the handle rotating inward and reduce the noise generated by the rebound. That is, the damped buffer door handle improves the user experience by gradually decreasing the damping force of the handle rotating outward and gradually increasing the damping force of the handle rotating inward.

[0018] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0036] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0037] Refer to Figures 1 to 7 As shown, a damping buffer door handle according to an embodiment of the present invention is applied to the door of a vehicle. The damping buffer door handle includes: a base 100, a torsion spring 200, and a handle 300.

[0038] Among them, the base 100 has an open accommodating space 110. The base 100 can be connected to the vehicle door so that the damping buffer door handle can be used as a door handle of an automobile. The base 100 can provide a supporting function for components such as the torsion spring 200 and the handle 300. The base 100 has an open accommodating space 110, and a chute 120 is provided on the side wall of the accommodating space 110.

[0039] The torsion spring 200 is disposed in the accommodating space 110. One end of the handle 300 is rotatably connected to the base 100. By rotating the handle 300 outward or inward, the handle 300 can enter and exit the accommodating space 110. A torsion spring 200 is provided at the rotational connection between the handle 300 and the base 100. The torsion spring 200 abuts against the handle 300 and the base 100. Due to the torsion force of the torsion spring 200, the handle 300 has a tendency to rotate and reset relative to the inside of the accommodating space 110.

[0040] An abutting block 410 is elastically connected to the side of the handle 300 of the damping buffer door handle, so that the abutting block 410 has a tendency to move towards the sliding groove 120, and the abutting block 410 abuts against the bottom wall of the sliding groove 120, thereby providing a certain damping force for the rotation of the handle 300. And the distance between the bottom wall of the sliding groove 120 and the side of the handle 300 gradually increases from inside to outside.

[0041] When the user pulls the handle 300 to rotate outwards against the torsion of the torsion spring 200, through the elastic connection between the side of the handle 300 and the abutting block 410, the abutting block 410 remains in contact with the bottom wall of the sliding groove 120, thereby providing a certain damping. Since the distance between the bottom wall of the sliding groove 120 and the side of the handle 300 gradually increases from inside to outside, as the handle 300 gradually rotates outwards, the pressure exerted by the abutting block 410 on the bottom wall of the sliding groove 120 gradually decreases, that is, the damping for the handle 300 to rotate outwards gradually decreases, so as to facilitate the user to rotate the handle 300 outwards.

[0042] The torsion spring 200 is connected to the handle 300 and the base 100 to drive the handle 300 to rotate and reset towards the inside of the accommodating space 110. When the user releases the pulling force on the handle 300, under the action of the torsion spring 200, the handle 300 rotates and resets towards the inside of the accommodating space 110. Since the distance between the bottom wall of the sliding groove 120 and the side of the handle 300 gradually decreases from outside to inside, as the handle 300 gradually rotates inwards, the pressure exerted by the abutting block 410 on the bottom wall of the sliding groove 120 gradually increases, that is, the damping for the handle 300 to rotate inwards gradually increases, which can effectively buffer the impact force when the handle 300 rotates inwards and reduce the noise generated by the rebound.

[0043] Compared with some door handle structures that use air springs and one-way dampers to achieve damping and buffering, the damping buffer door handle provided by the embodiment of the present invention has a gradually decreasing damping force when the handle 300 rotates outwards and a gradually increasing damping force when the handle 300 rotates inwards, thereby improving the user experience.

[0044] It can be understood that the upper end of the handle 300 is rotatably connected to the base 100, so that the handle 300 can rotate around an axis extending left and right to realize the outward rotation or inward rotation of the handle 300, that is, the damping buffer door handle is an upward-lifting door handle, and the user can lift the handle 300 upwards, so that the handle 300 passes through the accommodating space 110 to realize the unlocking of the car door.

[0045] The lower end of the handle 300 is provided with an upwardly concave grip groove 321. The abutting block 410 is connected to the left or right side of the handle 300. When the handle 300 is embedded in the accommodating space 110, there is a gap between the lower end of the handle 300 and the lower wall surface of the accommodating space 110. The gap between the lower end of the handle 300 and the lower wall surface of the accommodating space 110 allows the user's finger to penetrate and hold the grip groove 321. By pulling the handle 300 upward and rotating it outward, the unlocking of the vehicle door can be achieved.

[0046] The damped buffer door handle has a closed state. The closed state is that the handle 300 is embedded in the accommodating space 110, and the outer end surface of the handle 300 is flush with the outer end surface of the base 100. That is, the damped buffer door handle can be a hidden door handle. When the damped buffer door handle is in the closed state, the handle 300 is built into the accommodating space 110, that is, the outer end surface of the handle 300 is flush with the outer end surface of the base 100, so as to reduce the wind resistance caused by the exposure of the handle 300 and improve the endurance and high-speed driving stability of the vehicle applying the damped buffer door handle.

[0047] It should be understood that in some other embodiments, the handle 300 can be rotatably connected to the base 100 around an axis extending vertically, and the handle 300 can also be rotated in and out of the accommodating space 110.

[0048] It can be understood that in this embodiment, specifically, the damped buffer door handle further includes a compression elastic member 420. The compression elastic member 420 can specifically be a spring. A clamping groove 330 opposite to the sliding groove 120 is provided on the side wall of the handle 300. The compression elastic member 420 is arranged in the clamping groove 330. By the abutment of the compression elastic member 420 with the peripheral wall of the clamping groove 330, the telescopic direction of the compression elastic member 420 can be restricted, ensuring that both ends of the compression elastic member 420 are respectively abutted against the bottom wall of the clamping groove 330 and one end of the abutting block 410. When the compression elastic member 420 is compressed, the compression elastic member 420 can apply an elastic force towards the sliding groove 120 to the abutting block 410, so as to ensure that the other end of the abutting block 410 remains in abutment with the bottom wall of the sliding groove 120.

[0049] Taking the chute 120 provided on the right side wall of the accommodation space 110 as an example, the bottom wall of the chute 120 is gradually inclined to the right from the inside to the outside, that is, the bottom wall of the chute 120 is inclined, so that a high slope is formed inside the chute 120 and a low slope is formed outside the chute 120. When the handle 300 rotates from the inside to the outside, with the elastic action of the compression elastic member 420, the abutting block 410 slides from the high slope of the chute 120 to the low slope, so that the pressure exerted by the abutting block 410 on the bottom wall of the chute 120 gradually decreases, that is, the damping force for rotating the handle 300 gradually decreases, facilitating the user to rotate the handle 300 outwards. Conversely, when the handle 300 rotates from the outside to the inside, with the elastic action of the compression elastic member 420, the abutting block 410 slides from the low slope of the chute 120 to the high slope, so that the pressure exerted by the abutting block 410 on the bottom wall of the chute 120 gradually increases, that is, the damping force for rotating the handle 300 gradually increases, which can effectively buffer the impact force when the handle 300 rotates inwards and reduce the noise generated by the rebound.

[0050] It should be understood that in some other embodiments, the chute 120 is provided on the left side wall of the accommodation space 110.

[0051] It can be understood that in this embodiment, the cross-section of the card slot 330 is square. Accordingly, the abutting block 410 is arranged in a square column shape, so that the outer peripheral wall of the abutting block 410 can be in mutual abutting cooperation with the inner peripheral wall of the card slot 330, thereby restricting the rotation of the abutting block 410 and enhancing the guiding effect on the abutting block 410, and cooperating with the elastic force of the compression elastic member 420 to ensure that the abutting block 410 remains in abutment with the bottom wall of the chute 120.

[0052] It should be understood that in some other embodiments, the card slot 330 can be a cylindrical groove body. Accordingly, the abutting block 410 can be a cylinder to realize the guiding of the card slot 330 to the abutting block 410.

[0053] It can be understood that in this embodiment, the compression elastic member 420 is a spring. A positioning post 340 extending towards the chute 120 is provided on the bottom wall of the card slot 330. The spring is sleeved on the positioning post 340. By the mutual abutment of the positioning post 340 and the spring, the telescopic direction of the spring can be effectively restricted, ensuring that the elastic force provided by the spring for the abutting block 410 is more stable and reliable.

[0054] It should be understood that in some other embodiments, the compression elastic member 420 can be made of elastic materials such as rubber columns and silicone columns.

[0055] It can be understood that in this embodiment, one end of the abutting block 410 close to the chute 120 has an abutting end, and the abutting end gradually narrows towards the direction close to the bottom wall of the chute 120 to reduce the contact area between the abutting block 410 and the bottom wall of the chute 120, ensuring the smoothness of the rotation of the handle 300.

[0056] It is understandable that a positioning groove is provided at one end of the abutting block 410 facing away from the sliding groove 120. One end of the positioning column 340 close to the sliding groove 120 and one end of the spring close to the sliding groove 120 can be embedded in the positioning groove. Through the setting of the positioning groove, it can effectively prevent the abutting block 410 from colliding with the positioning column 340 during the sliding process. The other end of the spring can exert pressure on the bottom wall of the positioning groove, thereby driving the abutting block 410 to have a tendency to approach the bottom wall of the sliding groove 120, so as to ensure that the abutting block 410 can keep abutting against the bottom wall of the sliding groove 120.

[0057] It is understandable that the handle 300 includes a housing 320 and a rotating arm 310. A holding groove 321 is provided on the housing 320. The rotating arm 310 includes a first sub-bar 311 and a second sub-bar 312 arranged at an angle. The first sub-bar 311 and the second sub-bar 312 are arranged at an obtuse angle. The upper end of the first sub-bar 311 is rotatably connected to the base 100. The first sub-bar 311 gradually inclines inward toward the accommodating space 110 from top to bottom. The lower end of the first sub-bar 311 is fixedly connected to the upper end of the second sub-bar 312. The lower end of the second sub-bar 312 is fixedly connected to the housing 320.

[0058] Compared with the way that the housing 320 is rotatably connected to the base 100 through a straight rod, the rotating arm 310 of this damping buffer door handle has a first sub-bar 311 and a second sub-bar 312 arranged at an angle. And when the handle 300 is embedded in the accommodating space 110, the connection part of the first sub-bar 311 and the second sub-bar 312 is located inside the accommodating space 110, which can effectively reduce the obstruction caused by the rotating arm 310 to the rotation of the housing 320, so that the housing 320 has a larger rotation angle, makes full use of the internal space of the accommodating space 110, and realizes the accommodation and rotational connection of the rotating arm 310.

[0059] Specifically, a clamping groove 330 is provided at the connection part of the first sub-bar 311 and the second sub-bar 312. Specifically, the first sub-bar 311 and the second sub-bar 312 can be integrally formed parts by processes such as injection molding, and a clamping groove 330 is formed at the connection part of the first sub-bar 311 and the second sub-bar 312. Correspondingly, the compression elastic member 420 and the abutting block 410 are both arranged in the clamping groove 330. Appropriately, one end of the sliding groove 120 extends outward from the inside of the accommodating space 110, and the sliding groove 120 adapted to the swinging track of the housing 320 can be arranged in an arc shape.

[0060] It is understandable that the damped buffer door handle further includes a rotating shaft 500 connected to the base 100. There are two swing arms 310. Perforations are respectively provided at the upper ends of the two swing arms 310, and both ends of the rotating shaft 500 are respectively inserted through the two perforations to achieve the rotational connection between the rotating shaft 500 and the two swing arms 310. Considering that this damped buffer door handle is an upward-opening door handle and the handle 300 has a relatively large length in the left-right direction, the rotational connection between the housing 320 and the base 100 is achieved through the two swing arms 310, which is beneficial to improving the rotational stability of the housing 320.

[0061] The torsion spring 200 is sleeved on the rotating shaft 500, and the torsion spring 200 abuts against the base 100 and the swing arm 310. When the swing arm 310 rotates relative to the base 100, the torsion spring 200 can generate a torsional force. And when the user releases the pulling force on the handle 300, under the action of the torsional force of the torsion spring 200, the handle 300 can rotate and reset towards the inside of the accommodating space 110.

[0062] It is understandable that the accommodating space 110 includes a through hole 113, an inner cavity 112 and an outer cavity 111. The inner cavity 112 opens inwards, the outer cavity 111 opens outwards, and the inner cavity 112 and the outer cavity 111 are arranged vertically. The through hole 113 is provided between the inner cavity 112 and the outer cavity 111, and the upper end of the through hole 113 communicates with the inner cavity 112, and the lower end of the through hole 113 communicates with the outer cavity 111.

[0063] The handle 300 is inserted through the through hole 113. One end of the handle 300 is rotatably connected to the base 100 and is arranged at the inner cavity 112. During assembly, the user can insert the handle 300 through the through hole 113 and achieve the combination of the swing arm 310, the rotating shaft 500, the torsion spring 200 and the base 100, and then connect the base 100 to the outer door to be provided, so as to hide components such as the rotating shaft 500 and the torsion spring 200. The outer cavity 111 opens outwards, allowing the user to insert the hand into the outer cavity 111 and hold the housing 320.

[0064] The through hole 113 has a first side wall and a second side wall arranged oppositely. The first side wall is located at the end close to the outside, and the second side wall is located at the end close to the inside. The other end of the handle 300 can enter and exit the outer cavity 111. The through hole 113 can limit the rotation angle of the handle 300. When the handle 300 rotates outwards to the maximum angle, the handle 300 can abut against the first side wall of the through hole 113 to limit the maximum outward rotation angle of the handle 300. When the handle 300 rotates inwards to the maximum angle under the action of the torsion spring 200, the handle 300 can abut against the second side wall of the through hole 113 to support the handle 300.

[0065] A vehicle provided by an embodiment of the present invention includes a damping buffer door handle as shown in any of the above embodiments. The base 100 can be installed on the vehicle door. The base 100 has an open accommodation space 110, and a chute 120 is provided on the side wall of the accommodation space 110. One end of the handle 300 is rotatably connected to the base 100. By rotating the handle 300 outward or inward, the handle 300 can enter and exit the accommodation space 110. A chute 120 is provided on the side wall of the accommodation space 110. Correspondingly, a contact block 410 is elastically connected to the side of the handle 300. The contact block 410 abuts against the bottom wall of the chute 120, and the distance between the bottom wall of the chute 120 and the side of the handle 300 gradually increases from inside to outside. When the user pulls the handle 300 to rotate outward against the torsion of the torsion spring 200, through the elastic connection between the side of the handle 300 and the contact block 410, the contact block 410 abuts against the bottom wall of the chute 120, thereby providing a certain damping. Since the distance between the bottom wall of the chute 120 and the side of the handle 300 gradually increases from inside to outside, as the handle 300 rotates outward gradually, the pressure exerted by the contact block 410 on the bottom wall of the chute 120 gradually decreases, that is, the damping for the handle 300 to rotate outward gradually decreases, so as to facilitate the user to rotate the handle 300 outward. The torsion spring 200 is connected to the handle 300 and the base 100 to drive the handle 300 to rotate inward and reset into the accommodation space 110. When the user releases the pulling force on the handle 300, under the action of the torsion spring 200, the handle 300 rotates inward and resets into the accommodation space 110. Since the distance between the bottom wall of the chute 120 and the side of the handle 300 gradually decreases from outside to inside, as the handle 300 rotates inward gradually, the pressure exerted by the contact block 410 on the bottom wall of the chute 120 gradually increases, that is, the damping for the handle 300 to rotate inward gradually increases, which can effectively buffer the impact force when the handle 300 rotates inward and reduce the noise generated by the rebound. That is, the damping buffer door handle has a gradually decreasing damping force when the handle 300 rotates outward and a gradually increasing damping force when the handle 300 rotates inward, thereby improving the user experience.

[0066] The vehicle can be a private car, such as a sedan, an SUV, an MPV or a pickup truck, etc. The vehicle can also be an operating vehicle, such as a minivan, a bus, a small truck or a large trailer, etc. The vehicle needs to have an electric motor that can output power or store mechanical energy as a generator. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0067] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
