Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicles, in particular to a hinge assembly, a vehicle door and a vehicle. BACKGROUND

[0002] With the continuous development of automobile technology, in order to bring better riding experience to users, the functions of vehicles are more and more diverse.

[0003] The door of the automobile is usually connected with the vehicle body through a hinge, and the opening and closing of the door is realized through the opening and closing movement of the hinge.

[0004] However, when opening the door, a small force can directly open the door to the maximum position, and if there are obstacles around the vehicle, the door is easy to collide. CONTENT OF THE UTILITY MODEL

[0005] The purpose of the present application is to provide a hinge assembly, a vehicle door and a vehicle, aiming to solve the problem of how to reduce the collision when opening the door.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] In the first aspect, the present application provides a hinge assembly, which can include a first hinge base with a hinge shaft and a second hinge base with a hinge hole, the hinge shaft is rotatably connected with the hinge hole, so that the first hinge base and the second hinge base can rotate around the central axis of the hinge shaft.

[0008] One of the first hinge base and the second hinge base is adapted to be connected with the vehicle body, and the other is adapted to be connected with the door, so that when the first hinge base and the second hinge base rotate around the central axis of the hinge shaft, the door can rotate around the central axis of the hinge shaft, thereby realizing the opening and closing of the door.

[0009] The limiting module can include a stop piece connected with the hinge shaft, and a stop base connected with the second hinge base; the stop piece is provided with a protruding part, and the stop base is provided with a groove matched with the protruding part; when the stop piece rotates with the hinge shaft, the protruding part can slide into and out of the groove.

[0010] When the door is subjected to the opening force, the protruding part can slide into the groove, and when a constant and small force is applied, the protruding part is matched with the groove and placed in the groove, and as the opening force increases, the static friction force between the protruding part and the peripheral wall of the groove increases, finally making the protruding part slide out of the groove and disengage from the groove. In this way, the cooperation of the stop piece and the stop base can make the door hover to the position where the protruding part cooperates with the groove when the door is opened, so as to reduce the door from being uncontrollably opened to the maximum position and colliding with the obstacle.

[0011] In some embodiments, the limiting module further comprises a cover connected to the second hinge base, the cover is provided with a containing space, and the protrusion and the groove are arranged in the containing space.

[0012] In this way, the lubricating grease can be saved between the protrusion and the groove, the opening of the door is smoother, the sealed limiting module can avoid foreign matters from entering the limiting module, the generation of abnormal sound is reduced, and the service life of the limiting module is improved.

[0013] In some embodiments, the cover comprises a second cover, and the containing space is formed after the gear base and the second cover are closed.

[0014] Since the gear base and the second cover are designed in a split type, the containing space is formed after the gear base and the second cover are closed, and therefore, the limiting module can be conveniently overhauled and adjusted.

[0015] In some embodiments, the cover comprises a first cover and a second cover, the containing space is formed after the first cover and the second cover are closed, and the gear base is connected between the first cover and the gear piece.

[0016] Since the first cover and the second cover are designed in a split type, the containing space is formed after the first cover and the second cover are closed, and therefore, the limiting module can be conveniently overhauled and adjusted.

[0017] In some embodiments, the limiting module further comprises a second elastic piece, and the second elastic piece is elastically supported between the second cover and the gear piece.

[0018] In this way, when the protrusion slides out of the groove, the second elastic piece is extruded and compressed, at this time, the elastic force of the second elastic piece is increased, so that the pressure between the protrusion and the peripheral wall of the groove is increased, the static friction force is increased, and a larger force needs to be applied to make the protrusion slide out of the groove. When the protrusion slides into the groove, the second elastic piece is deformed and restored, elastically supports the protrusion and the groove, and the door can be suspended at this position to form a gear.

[0019] In some embodiments, a guide surface is formed between a side wall surface of the gear piece facing the gear base and a bottom wall of the groove, the protrusion is adapted to abut against the guide surface and can slide along the guide surface.

[0020] The guide surface can facilitate the sliding of the protrusion into and out of the groove, so that the opening and closing of the door are smooth, the abnormal sound and jamming when the door is opened are reduced, and the service life of the limiting module is improved.

[0021] In some embodiments, the guide surface is a circular arc surface or an inclined surface. When the guide surface is a circular arc surface, the guide surface can provide a smooth motion track, which helps to reduce vibration and noise and improve the stability of operation. When the guide surface is an inclined surface, the guide surface is simple to manufacture, and the cooperation accuracy of the groove and the protrusion can be improved.

[0022] In some embodiments, the gear is provided with an annular groove on one side close to the second cover, and at least part of the second elastic member is arranged in the annular groove. Arranging at least part of the second elastic member in the annular groove helps to save the space requirement of the second elastic member.

[0023] In some embodiments, the gear base is provided with a limiting groove on one side away from the gear, and the limiting module further comprises a limiting block connected with the hinge shaft, and the limiting block is capable of sliding in the limiting groove.

[0024] In this way, the limiting groove can limit the movement track of the limiting block, so as to limit the rotation of the hinge shaft, and further limit the opening and closing of the door.

[0025] In some embodiments, the limiting block has at least a first limit position and a second limit position in the limiting groove. When the limiting block is located at the first limit position, the first hinge base and the second hinge base cooperate to adapt to the complete opening of the door. When the limiting block is located at the second limit position, the first hinge base and the second hinge base cooperate to adapt to the closing of the door.

[0026] In this way, the simple limiting module can limit the maximum opening angle of the door, when the limiting block is located at the first limit position.

[0027] In some embodiments, the limiting module has at least a first working state and a second working state. When the limiting module is located at the first working state, the limiting module limits the rotation of the hinge shaft. When the limiting module is located at the second working state, the limiting module is free from the rotation limitation of the hinge shaft.

[0028] When the limiting module is located at the first working state, the limiting module can limit the rotation of the hinge shaft, so as to limit the movement of the door. When the limiting module is located at the second working state, the limiting module is free from the rotation limitation of the hinge shaft, so that the hinge shaft can rotate, thereby enabling the door to rotate.

[0029] In this way, the hinge assembly can adjust the limiting module to be in the first working state or the second working state, so as to limit or release the rotation of the hinge shaft, thereby locking or unlocking the door, and further improving the safety during driving to prevent passengers from falling off due to the door being opened by mistake.

[0030] In some embodiments, the limiting module comprises a driving member, a limiting member, and a limiting structure connected with the hinge shaft. The driving member is in transmission connection with the limiting member to enable the limiting member to rotate, and has at least a first position and a second position. When the limiting member is located at the first position, the limiting module is located at the first working state. When the limiting member is located at the second position, the limiting module is located at the second working state.

[0031] The driving member can drive the limiting member to rotate. When the limiting member rotates to the first position, the limiting member can limit the movement of the limiting structure. Since the limiting structure is connected to the hinge shaft, the limiting member can limit the rotation of the hinge shaft, thereby limiting the movement of the door, and achieving the locking of the door. When the limiting member rotates to the second position, the limiting member is disengaged from the limiting structure, and the hinge shaft can rotate, thereby opening the door.

[0032] In some embodiments, the limiting structure includes a limiting rod arranged circumferentially around the hinge shaft; the limiting member includes a block, the driving member is adapted to drive the block to rotate in a first direction, and the block is elastically connected to the driving member in the first direction, which is the direction of the central axis of the hinge shaft; the block is provided with a guide slope; when the limiting member is in the first position, the limiting rod abuts against the peripheral wall of the block; and when the limiting member is in the second position, the limiting rod can slide along the guide slope.

[0033] The driving member can drive the block to rotate in the direction of the central axis of the hinge shaft. Since the block is provided with a guide slope, when the driving member drives the block to rotate to the second position, i.e., when the guide slope is opposite to the limiting rod, the limiting rod can pass over the block by the guiding action of the guide slope. At this time, the block is disengaged from the limiting rod, thereby allowing the door to be normally opened and closed.

[0034] When the driving member drives the block to rotate to the first position, i.e., when the guide slope intersects with the limiting rod, the peripheral wall of the block abuts against the limiting rod, and the limiting rod cannot pass over the block. At this time, the block can limit the movement of the limiting rod, thereby limiting the clockwise rotation of the hinge shaft from the current position, and further limiting the opening of the door, and completing the locking of the door. In this way, the limiting module can complete the driving locking function and the child locking function, reduce the safety accidents caused by the accidental opening of the door by the passengers, and ensure the safety of the children left alone in the car.

[0035] In some embodiments, the limiting module includes a first elastic member arranged between the driving member and the block, and adapted to elastically support the block.

[0036] In this way, when the limiting rod slides on the guide slope, the first elastic member can be compressed, thereby allowing the block to move towards the driving member, and further allowing the limiting rod to smoothly pass through the block, and realizing the opening and closing of the door.

[0037] In some embodiments, the first elastic member includes a compression spring. The compression spring can absorb and store energy. When the limiting rod slides upward along the guide slope, the spring can be deformed by contraction. When the limiting rod moves away from the block, the spring can recover to the original shape. Since the spring structure is simple, easy to manufacture, and has high reliability, the block can be well elastically supported.

[0038] In some embodiments, the limiting module comprises a transmission shaft, the transmission shaft is in transmission connection with the hinge shaft, and the limiting rod is connected to the circumferential wall of the transmission shaft.

[0039] The transmission shaft is in transmission connection with the hinge shaft, and when the hinge shaft rotates, the transmission shaft can rotate following the rotation of the hinge shaft. Since the limiting rod is connected to the circumferential wall of the transmission shaft, the stop block can limit the rotation of the transmission shaft, thereby limiting the rotation of the hinge shaft. Through the transmission connection between the transmission shaft and the hinge shaft, the position of the limiting module is not limited by the position of the hinge shaft, so that the space can be reasonably utilized, and the multifunctionalization of the vehicle is facilitated.

[0040] In some embodiments, the cover comprises a first cover connected with the second cover, and the limiting member is connected to the first cover; the limiting module further comprises a fixing block connected to the first cover, the fixing block and the limiting member are arranged in the circumferential direction of the hinge shaft, and the limiting structure can move between the limiting member and the fixing block.

[0041] In this way, the fixing block can limit the maximum displacement of the limiting structure in the clockwise direction, thereby limiting the maximum opening angle of the vehicle door.

[0042] In some embodiments, the limiting module further comprises a third elastic member, at least part of the third elastic member is arranged between the limiting structure and the fixing block.

[0043] Since at least part of the third elastic member is arranged between the limiting structure and the fixing block, when the vehicle door is opened to the maximum opening angle, the third elastic member can buffer the vehicle door and the fixing block, preventing damage to the vehicle door or the limiting module due to excessive opening force, thereby prolonging the service life of the limiting module.

[0044] In some embodiments, the third elastic member comprises a torsion spring, one end of the torsion spring is connected to the stop block base, the other end of the torsion spring is connected to the first cover, the torsion spring comprises a torsion portion, the torsion portion can be in contact with the limiting structure, and at least part of the torsion portion is arranged between the limiting structure and the fixing block.

[0045] The two ends of the torsion spring are connected to the stop block base and the first cover, at least part of the torsion portion is arranged between the limiting structure and the fixing block, when the external object collides with the vehicle door, the torsion portion is extruded and twisted to the position of the fixing block, the torsion spring can absorb energy, buffer the impact caused by the collision, and reduce the damage. Since the torsion spring has a high elastic limit range, in the case of a large torsion angle, the torsion spring can maintain good elasticity and repeatability, thereby improving the service life of the limiting module.

[0046] In some embodiments, the hinge assembly can further comprise a driving assembly connected to the hinge shaft.

[0047] The rotation of the hinge shaft can be controlled by the driving assembly, and the opening and closing of the door can be driven, so that one-key opening or one-key closing of the door can be realized by the vehicle control system in rainy and snowy weather or when the user has sundries in hand and cannot open the door conveniently, and the convenience of the vehicle is improved.

[0048] In some embodiments, the driving assembly can include a motor, and an output shaft of the motor is connected with the hinge shaft.

[0049] In this way, the output shaft of the motor and the rotation shaft of the door can be on the same axis, the power output is more stable, and power loss caused by the transmission process is reduced.

[0050] In some embodiments, the hinge assembly can further include a transmission assembly connected between the limiting module and the hinge shaft.

[0051] In this way, the position of the limiting module is not limited by the position of the hinge shaft, so that the space can be reasonably utilized, and the multifunctionalization of the vehicle is facilitated.

[0052] In some embodiments, the transmission assembly can include first and second gears engaged with each other, the first gear is connected with the transmission shaft and rotates synchronously, and the second gear is connected with the hinge shaft and rotates synchronously.

[0053] In this way, the limiting module and the hinge shaft can be on different axes, and the installation and fixation of the limiting module are facilitated. The first gear is connected with the transmission shaft and rotates synchronously, and the second gear is connected with the hinge shaft and rotates synchronously. When the hinge shaft rotates, the second gear, the first gear and the transmission shaft can be sequentially driven to rotate, so that the present function and the gear suspension function of the limiting module are realized.

[0054] In some embodiments, the diameter of the first gear is smaller than the diameter of the second gear.

[0055] Since the diameter of the first gear is smaller than the diameter of the second gear, when the hinge shaft rotates, the rotation angle of the hinge shaft is smaller than the rotation angle of the gear piece. When the protruding part rotates one circle along the circumferential direction of the gear base, the door is not opened to the maximum position, and the protruding part can continue to rotate to form more gears.

[0056] In a second aspect, the application further provides a door, which can include the hinge assembly.

[0057] In a third aspect, the application further provides a vehicle, which can include the hinge assembly or the door. It should be noted that the technical effects brought by the implementation manners of the second aspect and the third aspect can be referred to the technical effects brought by the corresponding implementation manners in the first aspect, and will not be described here.

[0084] With the continuous development of automobile technology, in order to bring users a more comfortable and safe driving experience, the functions of the vehicle are more and more diverse. In the prior art, the door of the automobile is usually connected with the vehicle body through a hinge, and the opening and closing of the door is realized through the opening and closing movement of the hinge.

[0085] However, when opening the door, a small force can directly open the door to the maximum position, and if there are obstacles around the vehicle, the door is easy to collide.

[0086] In view of this, the embodiments of the present application provide a hinge assembly, which is provided with a limiting module, the protruding part in the limiting module can slide into or out of the groove, through the cooperation of the protruding part and the groove, the door can be suspended to the cooperation position of the protruding part and the groove, so as to reduce the uncontrollable opening of the door to the maximum position and the collision with the obstacle.

[0087] The embodiments provided by the present application will be specifically introduced below in combination with the drawings of the specification.

[0088] Please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a hinge assembly 1000 provided by the embodiments of the present application, Figure 2 is Figure 1 the exploded view of the hinge assembly 1000 shown in the figure, the hinge assembly 1000 can include a first hinge base 100 and a second hinge base 200, wherein the first hinge base 100 has a hinge shaft 101, the second hinge base 200 has a hinge hole 201, the hinge shaft 101 can be rotatably connected with the hinge hole 201, so that the first hinge base 100 and the second hinge base 200 can rotate around the central axis of the hinge shaft 101.

[0089] One of the first hinge base 100 and the second hinge base 200 can be connected with the vehicle body, and the other can be connected with the door, so that when the first hinge base 100 and the second hinge base 200 rotate around the central axis of the hinge shaft 101, the door can rotate around the central axis of the hinge shaft 101, thereby realizing the opening and closing of the door.

[0090] The hinge assembly 1000 can further include a limiting module 300, which can have at least a first working state and a second working state. When the limiting module 300 is in the first working state, the limiting module 300 can limit the rotation of the hinge shaft 101, thereby limiting the movement of the door. In this way, when the vehicle starts to run, the limiting module 300 can be adjusted to the first working state, and the passenger cannot open the door by turning the wrench, thereby reducing the risk of door opening and ensuring driving safety.

[0091] When the limit module 300 is in the second working state, the limit module 300 is released from the rotation restriction of the hinge shaft 101, and the hinge shaft 101 can rotate, thereby allowing the door to rotate and the door to be opened. Thus, when the vehicle stops and the door needs to be opened, the limit module 300 is adjusted to the second working state to release the lock on the door, and passengers can open the door using the door opening wrench to complete the boarding or alighting.

[0092] In this way, the hinge assembly 1000 can adjust the limit module 300 to be in the first working state or the second working state, so that the rotation of the hinge shaft 101 is restricted or unrestricted, thereby locking or unlocking the door, which can improve safety during driving and prevent passengers from falling out when the door is accidentally opened.

[0093] In some embodiments, the limit module 300 can be controlled by the vehicle control system to realize the automatic door locking function while driving. When the vehicle control system detects that the vehicle has started to move, it automatically switches the limit module 300 from the second working state to the first working state to lock the door.

[0094] In addition, when the vehicle stops driving, the limit module 300 can also be manually adjusted to a first working state and a second working state. For example, when there are children in the car and the guardian leaves the vehicle briefly, the limit module 300 can be manually controlled to adjust to the first working state to limit the rotation of the hinge shaft 101, thereby locking the car door and preventing children from accidentally opening the car door and getting lost, or the car door from being opened by strangers from the outside.

[0095] Please refer to Figure 2 , Figure 3 and Figure 4 , Figure 3 for Figure 2 The exploded view of the limit module 300 shown is shown. Figure 4 for Figure 3 The enlarged view of the limiting module 300 at point A shows that, in some embodiments of this application, the limiting module 300 may include a driving member 301, a limiting member 302, and a limiting structure 303 connected to the hinge shaft 101. The driving member 301 is kinetically connected to the limiting member 302 to cause the limiting member 302 to rotate, and has at least a first position and a second position. When the limiting member 302 is in the first position, the limiting module 300 is in a first working state; when the limiting member 302 is in the second position, the limiting module 300 is in a second working state.

[0096] The driving member 301 can drive the limiting member 302 to rotate. When the limiting member 302 rotates to a first position, the limiting member 302 can limit the movement of the limiting structure 303. Since the limiting structure 303 is connected to the hinge shaft 101, the limiting member 302 can limit the rotation of the hinge shaft 101, thereby limiting the movement of the door and achieving the locking of the door. When the limiting member 302 rotates to a second position, the limiting member 302 is disengaged from the limiting structure 303, and the hinge shaft 101 can rotate, thereby enabling the door to be opened.

[0097] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 5 is a schematic view of the limiting module 300 in the first working state when the door is closed in the embodiment of the application, Figure 6 is a schematic view of the limiting module 300 in the second working state when the door is closed in the embodiment of the application. In some embodiments of the application, the limiting structure 303 can include a limiting rod 3031 arranged circumferentially on the hinge shaft 101. The limiting member 302 can include a stop block 3021. The driving member 301 is adapted to drive the stop block 3021 to rotate in a first direction, and the stop block 3021 is elastically connected to the driving member 301 in the first direction, which is the direction of the central axis of the hinge shaft 101. The stop block 3021 is provided with a guide slope 3022. When the limiting member 302 is in the first position, the limiting rod 3031 abuts against the circumferential wall of the stop block 3021. When the limiting member 302 is in the second position, the limiting rod 3031 can slide along the guide slope 3022.

[0098] The driving member 301 can drive the stop block 3021 to rotate in the direction of the central axis of the hinge shaft 101. Since the stop block 3021 is provided with the guide slope 3022, as Figure 6 shown, when the driving member 301 drives the stop block 3021 to rotate to the second position, i.e., when the guide slope 3022 is opposite to the limiting rod 3031, the limiting rod 3031 can pass over the stop block 3021 by the guiding action of the guide slope 3022. At this time, the stop block 3021 is disengaged from the limiting of the limiting rod 3031, thereby enabling the door to be normally opened and closed.

[0099] As Figure 5As shown, when the driving member 301 drives the block 3021 to rotate to the first position, that is, the guide slope 3022 intersects with the limiting rod 3031, the peripheral wall of the block 3021 abuts against the limiting rod 3031, the limiting rod 3031 cannot pass the block 3021, at this time, the block 3021 can limit the movement of the limiting rod 3031, thereby limiting the clockwise rotation of the hinge shaft 101 from the current position, further limiting the opening of the door, and completing the locking of the door. In this way, the limiting module 300 can complete the driving locking function and the child locking function, reduce the safety accidents caused by the accidental opening of the door by the passenger, and ensure the safety of the child alone in the vehicle.

[0100] Please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 , Figure 7 is a schematic view of the limiting module 300 in the first working state when the door is opened in the embodiment of the present application, Figure 8 is a schematic view of the limiting module 300 in the second working state when the door is opened in the embodiment of the present application, Figure 8 In the second position, the block 3021 rotates to the second position, that is, the guide slope 3022 is opposite to the limiting rod 3031, the limiting rod 3031 can pass the block 3021 through the guide action of the guide slope 3022, and the block 3021 has no limiting effect on the limiting rod 3031, at this time, the door can be switched from the open state to the closed state.

[0101] Figure 7 In the first position, when the limiting rod 3031 rotates to the block 3021, the peripheral wall of the block 3021 abuts against the limiting rod 3031, the limiting rod 3031 cannot pass the block 3021, and the hinge shaft 101 can be limited to rotate counterclockwise from the current position, and the door cannot be normally closed. In this way, the limiting module 300 can reduce the injury caused by the accidental closing of the door to the hand.

[0102] In some embodiments, the driving member 301 can be a micro motor. Since the micro motor is small in size, light in weight, and high in movement precision, it can be integrated with the block 3021 into the limiting module 300, thereby realizing the control of the block 3021.

[0103] In order to facilitate the limiting rod 3031 to pass the block 3021 through the guide slope 3022 when the limiting module 300 is in the second working state, in some embodiments of the present application, the limiting module 300 can further include a first elastic member 304, the first elastic member 304 is arranged between the driving member 301 and the block 3021, and is adapted to elastically support the block 3021.

[0104] In this way, when the limiting rod 3031 abuts against the guide slope 3022 and slides, the first elastic member 304 can be compressed, so that the stop block 3021 can move towards the driving member 301, and then the limiting rod 3031 can smoothly pass through the stop block 3021, thereby realizing the opening and closing of the vehicle door.

[0105] In some embodiments of the present application, the first elastic member 304 can include a compression spring 3041. The compression spring 3041 can absorb and store energy, and when the limiting rod 3031 slides upwards along the guide slope 3022, the spring can be deformed by contraction, and when the limiting rod 3031 leaves the stop block 3021, the spring can recover to the original shape. Since the spring structure is simple, easy to manufacture, and has high reliability, the stop block 3021 can be well elastically supported.

[0106] Please continue to refer to Figure 2 and Figure 3 In some embodiments of the present application, the limiting module 300 can further include a transmission shaft 305, the transmission shaft 305 is in transmission connection with the hinge shaft 101, and the limiting rod 3031 is connected to the peripheral wall of the transmission shaft 305.

[0107] The transmission shaft 305 is in transmission connection with the hinge shaft 101, and when the hinge shaft 101 rotates, the transmission shaft 305 can rotate following the rotation of the hinge shaft 101. Since the limiting rod 3031 is connected to the peripheral wall of the transmission shaft 305, the stop block 3021 can limit the rotation of the transmission shaft 305, thereby limiting the rotation of the hinge shaft 101.

[0108] By transmission connection between the transmission shaft 305 and the hinge shaft 101, the position of the limiting module 300 can not be limited by the position of the hinge shaft 101, so that the space can be reasonably utilized, which is beneficial to the multifunctionalization of the vehicle.

[0109] Please refer to Figure 2 and Figure 9 , Figure 9 for Figure 3 the structural schematic view of the transmission shaft 305, in some embodiments, a square hole 3051 is arranged in the transmission shaft 305, and at least part of the hinge shaft 101 has a square cross section, so that at least part of the hinge shaft 101 can cooperate with the transmission shaft 305 and cannot rotate in the interior of the transmission shaft 305. In this way, the hinge shaft 101 can rotate synchronously with the transmission shaft 305.

[0110] Please continue to refer to Figure 2 and Figure 3In a possible structural design, at least part of the hinge shaft 101 can pass through the hinge hole 201 to the limiting module 300, so that the first hinge base 100 rotates relative to the second hinge base 200 around the central axis direction of the hinge shaft 101.

[0111] In this way, the connecting relationship of the door hinge itself does not need to be changed, and the limiting module 300 can directly act on the rotating shaft and does not need to be changed due to the change of the door size, and is simple to manufacture and install.

[0112] In another possible structural design, at least part of the hinge shaft 101 can also pass through the limiting module 300 to the hinge hole 201.

[0113] In other possible structural designs, the limiting module 300 can also be integrated into the hinge hole 201, that is, a containing cavity can be formed in at least part of the hinge hole 201, the driving member 301, the limiting member 302, the limiting structure 303 and the first elastic member 304 are arranged in the containing cavity, and the rotation of the hinge shaft 101 is limited by the limiting action of the limiting member 302. In this way, the integration of the hinge assembly 1000 can be improved, and space can be saved.

[0114] In some embodiments of the present application, the limiting module 300 can further include a cover 306 connected with the second hinge base 200, the cover 306 has a containing space, and the driving member 301, the limiting member 302 and the limiting structure 303 are arranged in the containing space.

[0115] In this way, when the first hinge base 100 with the hinge shaft 101 rotates relative to the second hinge base 200, the cover 306 can be stationary relative to the second hinge base 200, and at least part of the hinge shaft 101 can rotate relative to the cover 306.

[0116] In addition, since the driving member 301, the limiting member 302 and the limiting structure 303 are arranged in the containing space, the influence of external sundries on the limiting module 300 can be reduced, and the stability of the limiting function can be improved.

[0117] In some embodiments of the present application, the cover 306 can include a first cover 3061 and a second cover 3062, the first cover 3061 is connected with the limiting member 302, and the first cover 3061 and the second cover 3062 form the containing space after being covered.

[0118] In this way, when the hinge shaft 101 rotates, the limiting structure 303 does not drive the limiting member 302 to rotate together, causing the limiting module 300 to fail, so that the reliability of the limiting module 300 can be ensured.

[0119] Since the first cover 3061 and the second cover 3062 are designed in a split type, the two covers form a containing space, so that the limit module 300 can be conveniently overhauled and adjusted.

[0120] Please refer to Figures 3-8 In some embodiments of the present application, the limit module 300 can further include a fixed block 307 connected to the first cover 3061, the fixed block 307 and the limit piece 302 are arranged along the circumferential direction of the hinge shaft 101, and the limit structure 303 can move between the limit piece 302 and the fixed block 307.

[0121] In this way, the fixed block 307 can limit the maximum displacement of the limit structure 303 in the clockwise direction, so as to limit the maximum opening angle of the door.

[0122] Please refer to Figure 3 、 Figure 8 and Figure 10 , Figure 10 is a structural schematic view of the door being opened to the maximum opening angle in the embodiments of the present application, and in some embodiments of the present application, the limit module 300 can further include a third elastic piece 308, at least part of the third elastic piece 308 is arranged between the limit structure 303 and the fixed block 307.

[0123] Since at least part of the third elastic piece 308 is arranged between the limit structure 303 and the fixed block 307, when the door is opened to the maximum opening angle, the third elastic piece 308 can buffer the door and the fixed block 307, preventing damage to the door or the limit module 300 due to excessive opening force, thereby prolonging the service life of the limit module 300.

[0124] Since the third elastic piece 308 can elastically deform, it can compress and deform when subjected to an external force, and it can return to the initial position when the external force is removed, so when the door is in the open state and is not subjected to force, the limit structure 303 is in the position shown in Figure 7 .

[0125] When an external object hits the door due to an unexpected situation, for example, a bicycle or a motorcycle passes by the vehicle and hits the door when the passenger opens the door, at this time, the limit structure 303 rotates from the position shown in Figure 8 to the position shown in Figure 10 , the third elastic piece 308 is extruded to generate compression and absorb the energy generated by the collision, reducing the damage caused by direct collision.

[0126] For example, the distance from the center axis of the hinge shaft 101 to the free end of the door is 1 meter, and the third elastic member 308 can generate a buffer of 175 mm at the free end of the door, so as to slow down the bicycle or motorcycle in a collision and reduce personal injury.

[0127] In some embodiments of the present application, the third elastic member 308 can include a torsion spring 3081, one end of the torsion spring 3081 is connected with the gear base 310, the other end is connected with the first cover 3061, and the torsion spring 3081 can include a torsion portion 3082, the torsion portion 3082 can be in contact with the limiting structure 303, and at least part of the torsion portion 3082 is arranged between the limiting structure 303 and the fixed block 307.

[0128] The torsion spring 3081 is connected at both ends with the gear base 310 and the first cover 3061, and at least part of the torsion portion 3082 is arranged between the limiting structure 303 and the fixed block 307. When a collision occurs, the torsion portion 3082 is extruded and twisted to the position shown in the figure, the torsion spring 3081 can absorb energy and buffer the impact caused by the collision, thereby reducing injury. Figure 10

[0129] Due to the high elastic limit range of the torsion spring 3081, the torsion spring 3081 can maintain good elasticity and repeatability in the case of a large torsion angle, so as to improve the service life of the limiting module 300.

[0130] The hinge assembly 1000 in the embodiments of the present application sets a limiting function at the maximum opening position and the closed position of the door, thereby improving the safety of the vehicle. However, during the opening of the door, a small force applied to the door can directly open the door to the maximum position, that is, a small force applied to the door can open the door to the position where the limiting structure 303 is in contact with the torsion portion 3082 of the torsion spring 3081. If there are obstacles around the vehicle, such as other vehicles or walls, the door is likely to collide with the obstacles.

[0131] Therefore, please refer to Figure 2 , Figure 3 , Figure 11 and Figure 12 , Figure 11 for Figure 3 the structural schematic diagram of the gear 309, Figure 12 for Figure 3 ​The second structural schematic diagram of the stop piece 309 shown, in some embodiments of the present application, the limiting module 300 can further include a stop piece 309 and a stop base 310, the stop piece 309 is connected with the hinge shaft 101, and the stop base 310 is connected between the first cover 3061 and the stop piece 309; the stop piece 309 is provided with a protruding part 3091, and the stop base 310 is provided with a groove 3101 matched with the protruding part 3091; when the stop piece 309 rotates with the hinge shaft 101, the protruding part 3091 can slide into and out of the groove 3101.

[0132] The stop piece 309 is connected with the hinge shaft 101, the stop piece 309 is provided with a protruding part 3091, and the stop base 310 is provided with a groove 3101 matched with the protruding part 3091, when the stop piece 309 rotates with the hinge shaft 101, the protruding part 3091 can slide into and out of the groove 3101, when the door is opened by force, the protruding part 3091 can slide into the groove 3101, when a constant and small force is applied, the protruding part 3091 is matched with the groove 3101 and placed in the groove 3101, as the opening force increases, the static friction between the protruding part 3091 and the peripheral wall of the groove 3101 increases, and finally the protruding part 3091 slides out of the groove 3101 and is separated from the groove 3101.

[0133] In this way, the cooperation of the stop piece 309 and the stop base 310 can make the door hover to the position where the protruding part 3091 is matched with the groove 3101 when the door is opened by using only a small force, so as to reduce the uncontrollable opening of the door to the maximum position and the collision with the obstacle.

[0134] In a possible structural design, the stop piece 309 connected with the hinge shaft 101 can include that the stop piece 309 is directly connected with the hinge shaft 101 through a matching part, so that the stop piece 309 rotates synchronously with the hinge shaft 101.

[0135] In another possible structural design, the stop piece 309 connected with the hinge shaft 101 can include that the stop piece 309 and the hinge shaft 101 can be connected through a transmission part, for example, the stop piece 309 is connected with the transmission shaft 305 through a matching part, and the transmission shaft 305 is in transmission connection with the hinge shaft, so that the stop piece 309 can rotate following the rotation of the hinge shaft 101.

[0136] In some embodiments, the matching part can be a limiting strip matched with each other, for example, a first limiting strip 3093 can be arranged on the inner wall of the stop piece 309, and a second limiting strip 3052 can be arranged on the outer wall of the transmission shaft 305, the first limiting strip 3093 and the second limiting strip 3052 are matched with each other, so that the stop piece 309 rotates synchronously with the transmission shaft 305.

[0137] In other embodiments, the matching component can also be an internal thread arranged on the inner wall of the gear 309 and an external thread arranged on the outer wall of the transmission shaft 305, which is not limited in the present application.

[0138] In some embodiments, the gear base 310 can be provided with a plurality of grooves 3101 arranged along the circumferential direction of the gear base 310, so that when the gear 309 rotates with the hinge shaft 101, the protruding portions 3091 can be sequentially slid out of and into the plurality of grooves 3101, so that the door can hover at multiple angles according to different scenes, improving the flexibility of the door.

[0139] In some embodiments, the gear 309 can also be provided with a plurality of protruding portions 3091 arranged along the circumferential direction of the gear base 310, and the plurality of protruding portions 3091 correspond one-to-one to the plurality of grooves 3101. In this way, when the door is opened, the plurality of protruding portions 3091 can be slid out of one groove 3101 and into the next adjacent groove 3101, which can increase the stability of the cooperation between the gear 309 and the gear base 310.

[0140] Please continue to refer to Figure 2 and Figure 3 In some embodiments of the present application, the limiting module 300 can also include a second elastic member 311 elastically supported between the second cover 3062 and the gear 309.

[0141] In this way, when the protruding portion 3091 slides out of the groove 3101, the second elastic member 311 is extruded and compressed, at which time the elastic force of the second elastic member 311 increases, so that the pressure between the protruding portion 3091 and the circumferential wall of the groove 3101 increases, and the static friction force increases. If the protruding portion 3091 is to be slid out of the groove 3101, a relatively large force needs to be applied. When the protruding portion 3091 slides into the groove 3101, the second elastic member 311 recovers from deformation and elastically supports the cooperation between the protruding portion 3091 and the groove 3101, so that the door can hover at this position, forming a gear.

[0142] In some embodiments of the present application, a guide surface 3102 is formed between the side wall of the gear base 310 facing the gear 309 and the bottom wall of the groove 3101, the protruding portion 3091 is adapted to abut against the guide surface 3102 and can slide along the guide surface 3102.

[0143] The guide surface 3102 can make the protruding part 3091 smoothly slide into and out of the groove 3101, so that the opening and closing of the door can be more smooth, thereby reducing the abnormal sound and jamming when the door is opened. In some embodiments, the guide surface 3102 can be a circular arc surface or an inclined surface. When the guide surface 3102 is a circular arc surface, the guide surface 3102 can provide a smooth motion trajectory, which helps to reduce vibration and noise and improve the smoothness of operation. When the guide surface 3102 is an inclined surface, the guide surface 3102 is simple to manufacture and can improve the matching accuracy of the groove 3101 and the protruding part 3091.

[0144] In some embodiments of the present application, the gear 309 is provided with an annular groove 3092 on one side close to the second cover 3062, and at least part of the second elastic member 311 is arranged in the annular groove 3092. Arranging at least part of the second elastic member 311 in the annular groove 3092 helps to save the space requirement of the second elastic member 311.

[0145] In some embodiments, the second elastic member 311 can include a spring. Since the spring can have a larger carrying capacity, the gear 309 and the gear base 310 can be well supported, and the door is less likely to shake when hovering.

[0146] In addition, since the gear base 310 is connected between the first cover 3061 and the gear 309, and the second elastic member 311 is elastically supported between the second cover 3062 and the gear 309, the gear base 310 and the gear 309 are arranged in the accommodation space. In this way, the protruding part 3091 and the groove 3101 can be arranged inside the sealed limiting module 300, the grease can be saved between the protruding part 3091 and the groove 3101, the opening of the door can be more smooth, the sealed limiting module 300 can avoid foreign matters from entering the limiting module 300, the generation of abnormal sound is reduced, and the service life of the limiting module 300 is improved.

[0147] Since the second cover 3062 and the first cover 3061 cover to form the accommodation space, and the second elastic member 311 is elastically supported between the second cover 3062 and the gear 309, the compression degree of the second elastic member 311 can be adjusted by adjusting the covering degree of the second cover 3062 and the first cover 3061, so that the elastic force of the second elastic member 311 can be adjusted according to the user's use habit, and the gear force of opening or closing the door can be changed, thereby forming a gear feeling that meets the user's habit.

[0148] Please refer to Figure 13 , Figure 13A structural schematic diagram of a limiting module 300 provided in an embodiment of the present application is shown in the figure. The limiting module 300 can include a second cover 3062, a blocking member 309, and a blocking base 310. The blocking base 310 and the second cover 3062 form a containing space after being closed.

[0149] In this way, the limiting module 300 can realize the blocking hovering function. Since the limiting module 300 does not include the first cover 3061, the limiting module 300 requires less space and is more convenient to install.

[0150] Please refer to Figure 13 and Figure 14 , Figure 14 for Figure 13 a structural schematic diagram of the blocking base 310. In some embodiments, the blocking base 310 is provided with a limiting slot 3103 on the side away from the blocking member 309. The limiting module 300 further includes a limiting block 3032 connected with the hinge shaft 101. The limiting block 3032 can slide in the limiting slot 3103.

[0151] In this way, the limiting slot 3103 can limit the movement track of the limiting block 3032, thereby limiting the rotation of the hinge shaft 101, and further limiting the opening and closing of the vehicle door.

[0152] In some embodiments, the limiting block 3032 has at least a first limit position and a second limit position when sliding in the limiting slot 3103. When the limiting block 3032 is located at the first limit position, the first hinge base 100 and the second hinge base 200 cooperate to adapt to the complete opening of the vehicle door. When the limiting block 3032 is located at the second limit position, the first hinge base 100 and the second hinge base 200 cooperate to adapt to the closing of the vehicle door.

[0153] In this way, the limiting module 300 can limit the maximum opening angle of the vehicle door. When the limiting block 3032 is located at the first limit position, the vehicle door is opened to the maximum angle.

[0154] Please continue to refer to Figure 1 and Figure 2 In some embodiments of the present application, the hinge assembly 1000 can further include a driving assembly 400 connected to the hinge shaft 101.

[0155] The rotation of the hinge shaft 101 can be controlled by the driving assembly 400, thereby driving the opening and closing of the vehicle door. In this way, in rainy and snowy weather or when it is inconvenient to open the door due to having sundries in hand, one-key opening or one-key closing of the door can be realized through the vehicle control system, thereby improving the convenience of the vehicle.

[0156] The driving assembly 400 is connected with the hinge shaft 101, which can include that the driving assembly 400 is directly connected with the hinge shaft 101, or the driving assembly 400 is connected with the hinge shaft 101 through a transmission component.

[0157] In some embodiments of the present application, the driving assembly 400 can include a motor 401, and an output shaft of the motor 401 is connected with the hinge shaft 101. In this way, the output shaft of the motor 401 can be in the same axis as the rotating shaft of the door, the power output is more stable, and the power loss caused by the transmission process is reduced.

[0158] Please refer to Figure 15 , Figure 15 A structure schematic diagram of a hinge assembly 1000 provided by an embodiment of the present application is shown in FIG. 6. In some embodiments of the present application, the hinge assembly 1000 can further include a transmission assembly 500, which is connected between the limiting module 300 and the hinge shaft 101. In this way, the position of the limiting module 300 is not limited by the position of the hinge shaft 101, so that the space can be reasonably utilized, which is beneficial to the multifunctionalization of the vehicle.

[0159] For example, the transmission assembly 500 can be a bevel gear, a chain or a belt, which is not limited in the present application. Through the transmission assembly 500, the limiting module 300 can be in different positions and directions, and the door space can be saved.

[0160] In some embodiments of the present application, the transmission assembly 500 can include a first gear and a second gear engaged with each other, the first gear is connected with and synchronously rotates with the transmission shaft 305, and the second gear is connected with and synchronously rotates with the hinge shaft 101. In this way, the limiting module 300 and the hinge shaft 101 can be in different axes, which is beneficial to the installation and fixation of the limiting module 300. The first gear is connected with and synchronously rotates with the transmission shaft 305, and the second gear is connected with and synchronously rotates with the hinge shaft 101. When the hinge shaft 101 rotates, the second gear, the first gear and the transmission shaft 305 can be sequentially driven to rotate, so that the present function and the gear suspension function of the limiting module 300 can be realized.

[0161] In some embodiments of this application, the diameter of the first gear is smaller than the diameter of the second gear. Since the first gear is connected to and rotates synchronously with the drive shaft 305, and the second gear is connected to and rotates synchronously with the hinge shaft 101, if the diameters of the first and second gears are equal, when the hinge shaft 101 rotates, the rotation angle of the hinge shaft 101 is the same as the rotation angle of the gear shift member 309. Therefore, the number of grooves 3101 provided on the gear shift base 310 is equal to the number of door opening positions. Because the diameter of the first gear is smaller than the diameter of the second gear, when the hinge shaft 101 rotates, the rotation angle of the hinge shaft 101 is smaller than the rotation angle of the gear shift member 309. When the protrusion 3091 rotates one revolution along the circumference of the gear shift base 310, the door is not fully opened, and the protrusion 3091 can continue to rotate, forming more gear positions.

[0162] Please refer to Figure 15 and Figure 16 , Figure 16 for Figure 5 The schematic diagram of the gearbox 510 shown illustrates that, in some embodiments, the transmission assembly 500 includes a gearbox 510, which may include a first gear 511 and a second gear 512, wherein the diameter of the first gear 511 is smaller than the diameter of the second gear 512. The gearbox 510 can protect the first gear 511 and the second gear 512, preventing foreign objects from causing gear jamming.

[0163] In some embodiments, the gearbox 510 may include a meshing third gear 513 and a fourth gear 514. The fourth gear 514 is coaxially arranged with the first gear 511, and the diameter of the third gear 513 is smaller than the diameter of the fourth gear 514. The third gear 513 is connected to the drive shaft 305 and rotates synchronously, and the second gear 512 is connected to the hinge shaft 101 and rotates synchronously.

[0164] This allows for a further increase in the angle difference between the drive shaft 305 and the hinge shaft 101, creating more gears.

[0165] In some embodiments, the hinge assembly 1000 may further include a thrust ring 600 connected between the limiting module 300 and the second hinge base 200, which can reduce the axial movement of the hinge shaft 101 and make the hinge assembly 1000 operate more stably.

[0166] In some embodiments, the hinge assembly 1000 may include only a first hinge base 100, a second hinge base 200, and an electric module, thereby enabling the function of electrically opening and closing the door.

[0167] In some embodiments, the hinge base may include only the first hinge base 100, the second hinge base 200, and the limiting module 300, thereby realizing the limiting function.

[0168] In some embodiments, the hinge base can integrate the first hinge base 100, the second hinge base 200, the limiting module 300 and the electric module, for example, the functions of the limiting module 300 and the electric module can be directly integrated in the hinge hole 201, so that the functions are more flexible.

[0169] The application further provides a vehicle door, which can comprise the hinge assembly 1000.
