As shown in fig. 1 to 4, an embodiment of the present application provides a hinge device, which is used in an automobile and is connected between a vehicle body and a vehicle door, and includes a fixed hinge assembly 200 and a movable hinge assembly 100, wherein the fixed hinge assembly 200 is connected with the vehicle body, and the movable hinge assembly 100 is connected with the vehicle door, so that the movable hinge assembly 100 can rotate relative to the fixed hinge assembly 200 during the process of rotating and opening the vehicle door relative to the vehicle body.

The fixed hinge assembly 200 comprises a revolving body 210, a moving groove 211 is arranged on the surface of the revolving body 210, the moving groove 211 can extend along the revolving circumferential direction of the revolving body 210, the movable hinge assembly 100 comprises an elastic mechanism 110, the elastic mechanism 110 is configured to move along the moving groove 211 along with the opening and closing of the vehicle door, namely, the elastic mechanism 110 is abutted against the surface of the revolving body 210, meanwhile, in the rotating opening and closing process of the vehicle door, the elastic mechanism 110 also rotates along with the vehicle door relative to the revolving body 210, and the elastic mechanism 110 has different elastic forces when being matched with different positions of the moving groove 211.

It can be understood that the multi-gear function of opening the vehicle door can be realized through the cooperation of the elastic mechanism 110 and the revolving body 210, that is, the elastic mechanism 110 can ensure a certain resistance to the revolving body 210 in the opening and closing process of the vehicle door, the kept gear feeling is clear, and the resistance can change along with the rotation of the movable hinge assembly, and meanwhile, because the elastic mechanism 110 only has the rotation around the revolving body 210 and the compression of part of the mechanism per se can rebound, the arrangement of the whole hinge device can reduce the occupied space in the vehicle door, improve the space utilization rate, further reduce the stamping depth of the vehicle door shell, and increase and expand the riding space in the vehicle.

In addition, the vehicle door does not need to be provided with a large-size avoiding space along the length direction of the vehicle door, so that the integral forming of the vehicle door is simpler, and the manufacturing difficulty and the production cost of a mold are reduced.

It should be noted that, when the vehicle door drives the movable hinge assembly 100 to rotate relative to the fixed hinge assembly 200, the rotation center of the movable hinge assembly 100 may be the center of the revolving body 210, and in the process that the elastic mechanism 110 rotates relative to the revolving body 210, the distance from the surface of the moving groove 211 to the rotation center of the revolving body 210 may be different, so that when the elastic mechanism 110 slides along the moving groove 211, the abutting state is maintained, and meanwhile, the distance from the center of the revolving body 210 also changes along with the rotation of the vehicle door, so that the elastic mechanism 110 can apply elastic forces of different magnitudes at different opening and closing positions of the vehicle door.

First, the specific structure of the elastic mechanism 110 and the manner of engaging with the moving groove 211 will be described in detail.

With continued reference to fig. 1 to 4, in a possible implementation manner, the elastic mechanism 110 may include an elastic member 111 and an abutting member 112, the abutting member 112 abuts against a groove surface of the moving groove 211, and the elastic member 111 is connected to the abutting member 112 and applies an elastic force to the abutting member 112 toward the rotation body 210.

It can be understood that the elastic member 111 indirectly abuts against the moving groove 211 through the abutting member 112, meanwhile, the elastic force of the elastic member 111 can ensure that the abutting member 112 always keeps an abutting state with the moving groove 211, and the extension lines of the compression and rebound directions of the elastic member 111 can pass through the center of the revolving body 210, so that the obvious gear entering and gear passing feeling can be ensured in the opening and closing process of the vehicle door, and the user experience is improved.

For example, the elastic member 111 may be a spring, and a connection manner of one end of the spring facing the rotation body 210 and the abutting member 112 may include, but is not limited to, clamping, welding, or the like, and in the product design process, the damping coefficient of the elastic member 111 may be selected according to a model of a specific automobile to which the hinge device is applied, that is, the model of the spring is selected to meet requirements of different application occasions for different elastic force ranges, which is not specifically limited in the embodiment of the present application.

In some embodiments, the abutting member 112 may be provided with a receiving groove 1121, the elastic mechanism 110 may further include a ball 113, the ball 113 may be disposed in the receiving groove 1121, and the ball 113 at least partially protrudes from the receiving groove 1121, and the ball 113 is configured to roll along the moving groove 211 with the opening and closing of the door.

It can be understood that the size of the opening of the receiving groove 1121 toward the revolving body 210 may be smaller than the diameter of the ball 113, so as to prevent the ball 113 from falling out of the receiving groove 1121, and during the opening and closing process of the vehicle door, the friction between the abutting member 112 and the receiving groove 1121 may be reduced by the rolling of the ball 113 relative to the moving groove 211, thereby ensuring the smoothness of the opening or closing process of the vehicle door.

In the case that the damping coefficient of the elastic member 111 is determined, the extension shape of the moving groove 211 determines the degree of compression of the elastic member 111 and the magnitude of the specific elastic force generated during the opening and closing of the door, and determines the position of the door opening position, which will be described below.

In a possible implementation manner, the groove surface of the moving groove 211 may extend along the circumferential direction of the rotator 210, and at least part of the groove surface has different distances from the rotation center of the rotator 210, and the groove surface of the moving groove 211 has different undulation states relative to the center of the rotator 210, that is, when the elastic mechanism 110 rotates relative to the rotator 210 and slides along the moving groove 211, the elastic member 111 is compressed and rebounds.

It can be understood that, in the door switching process, because the elasticity size of elastic component 111 can change, consequently, the different angle position that opens and shuts of door has the feel of the opening and shutting power of equidimension not, has clear gear lever promptly to can improve user experience, in addition, can maintain the state of door when different gears.

It should be noted that, according to the habit of a user normally opening or closing the door, the opening force required by the door immediately after opening is usually the largest, and when the door is closed, the door usually requires an auxiliary force having a closing tendency, so in the hinge device provided in the embodiment of the present application, when the groove surface of the moving groove 211 transits from the initial position (corresponding to the position where the abutment member 112 abuts when the door is closed) to the final position (corresponding to the position where the abutment member 112 abuts when the door is opened), the slope thereof increases, that is, transits from the lower position to the higher position of the moving groove 211, thereby ensuring that when the door is opened, the abutment member 112 initially slides along the moving groove 211 with a large damping force, and when the door is closed, the abutment member 112 moves from the higher position to the lower position of the moving groove 211 by the elastic force of the elastic member 111, and has an auxiliary force for closing the door.

In order to ensure the clarity of the gear sense when the movable hinge assembly 100 rotates relative to the rotator 210, a clamping slot 2111 may be provided on the slot surface of the moving slot 211, and the ball 113 on the abutting member 112 needs to overcome the elastic force of the elastic member 111, i.e., needs a certain over-gear force, to slide into and out of the clamping slot 2111.

With continued reference to fig. 1 to 4, in a possible implementation manner, the slot surface of the moving slot 211 may be provided with at least two clamping slots 2111, when the movable hinge assembly 100 rotates to a corresponding shift position, the clamping slots 2111 are used for clamping the balls 113, different clamping slots 2111 may be spaced along the extending direction of the moving slot 211, and each clamping slot is recessed relative to the moving slot 211.

It can be understood that when the door rotates to a certain gear, the ball 113 can be clamped into the corresponding clamping slot 2111 to provide a certain gear-passing force, and meanwhile, the stability of the opening state of the door is ensured, the door is prevented from excessively shaking, and the opening angle of the door corresponds to the setting position of the clamping slot 2111.

For example, there may be two detent slots 2111, namely a first detent slot 2111a and a second detent slot 2111b, and the maximum opening angle of the door may be 90 °, when the opening angle of the door is 40 °, the ball 113 slides into the first detent slot 2111a, and when the opening angle of the door is 70 °, the ball 113 slides into the second detent slot 2111 b. The specific setting number of the clamping slots 2111 and the corresponding relation with the opening angle of the vehicle door can be adjusted according to requirements, and the embodiment of the application is not particularly limited thereto.

It will be appreciated that the spacing between the first mounting element 120 and the abutment element 112 allows the resilient element 111 some deformation space to accommodate the opening and closing of the door, so that different positions of the door opening and closing have different opening or overtravel forces.

For example, a guide may be disposed in the mounting groove 121, and an end of the elastic member 111 inserted into the mounting groove 121 may be fixedly connected to the guide, thereby ensuring stability of the elastic member 111 in the mounting groove 121.

In some embodiments, the moveable hinge assembly 100 may further include an adjusting member 130, the adjusting member 130 is movably connected to the mounting groove 121, and the adjusting member 130 may abut against the elastic member 111 to change a compression amount of the elastic member 111.

It can be understood that the elastic member 111 has a certain initial compression amount, so that the user can adjust and change the elastic force of the elastic member 111 according to the requirement, thereby adjusting the opening and closing force of the door. When a user feels that the force for opening the vehicle door is larger, the adjusting piece 130 can be moved in the direction away from the revolving body 210, so that the compression amount of the elastic piece 111 is reduced, namely, the opening and closing force of the vehicle door is reduced, and when the user feels that the opening force of the vehicle door is smaller, or after the vehicle door is used for a period of time, the elastic force of the elastic piece 111 is attenuated, the adjusting piece 130 can be moved in the direction towards the revolving body 210, so that the compression amount of the elastic piece 111 is increased, namely, the opening and closing force of the vehicle door is improved, and by the arrangement, the user experience can be improved, and the service life is prolonged.

For example, the adjusting member 130 may be coaxially disposed with the elastic member 111, the adjusting member 130 may be a threaded fastener such as a bolt or a stud, the first mounting member 120 may be provided with a corresponding threaded hole, the adjusting member 130 may be screwed with the threaded hole, and the degree of compression of the elastic member 111 may be adjusted by rotating the direction of the adjusting member 130, and an end of the adjusting member 130 may abut against the guide member.

It can be understood that, by the installation of the second mounting member 220 with the vehicle body, the stability and reliability of the connection of the whole of the fixed hinge assembly 200 with the vehicle body can be ensured.

In some embodiments, the rotator 210 may further have a support portion 213 and a wrapping portion 214, the support portion 213 is connected to the hinge portion 212, the wrapping portion 214 may be wrapped around a circumferential outer side of the support portion 213, and an outer surface of the wrapping portion 214 may be used to form the moving groove 211.
