[0027] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0028] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. During actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0029] It is generally necessary to open the door for maintenance, inspection or other operations. Once the door is opened, it is necessary to ensure that it is in a stable position and will not be accidentally closed or moved. When the door is open, you can use the door stopper to limit it, which can ensure that the door remains stable in a specific position. The door stopper allows the door to remain in a predetermined position when it is opened, and will not be accidentally closed or moved.

[0030] Door checkers are an important part of vehicle door design, helping to limit the door's opening range and controlling the door's position. The main function of a door check is to limit the door's opening range. It ensures that the door does not open beyond a certain angle. Door checkers also help the door maintain a stable position when it is open. This makes it easier for passengers to enter and exit the vehicle, while also helping to prevent the door from being blown away by strong winds. By controlling the door's opening range, door checkers help reduce the risk of damage to the door by hitting other objects, such as walls or other vehicles, when it is opened or closed. Door checkers are usually made of metal or reinforced plastic and have a curved shape that connects to the door and the body of the vehicle, limiting the door's opening.

[0031] However, setting the door check and hinge separately may increase the complexity of the overall system. This involves more parts and mechanical connections, which may increase the risk of failure and also increase the difficulty of maintenance and repair. Due to the separate settings, the two systems may need to be maintained separately. This may lead to higher maintenance costs because the performance and reliability of both systems need to be considered. If the adjustment between the door check and hinge is not correct, it may cause the door to not find and lock the proper position correctly. This may cause the door to not close completely, or make noise or other problems during driving. Separating the door check and hinge may require more space and add some additional weight. This may have some impact on the overall performance and fuel efficiency of the vehicle. Separate settings may involve different parts from different suppliers, which may cause some system integration issues. The compatibility and working together of different parts may require more debugging and testing.

[0032] like Figure 1 , 2 As shown in FIG. 3 , a vehicle door hinge includes a first hinge seat 10 , a second hinge seat 20 , a limiting plate 30 , a limiting column 40 and an elastic unit 50 .

[0033] The first hinge seat 10 is preferably a hinge seat connected to a vehicle door, and its specific shape is selected according to the vehicle model.

[0034] The second hinge seat 20 is hinged to the first hinge seat 10 through the first hinge shaft 11. The second hinge seat 20 is preferably a hinge seat connected to the vehicle frame, and its specific shape is selected according to the vehicle model. The door in this application refers to the passenger compartment door of the vehicle, and may also be a trunk door or an engine compartment door, etc. The axis direction of the first hinge shaft 11 may be the up-down direction, the vehicle width direction, the vehicle length direction, etc. according to different door opening methods. The axis direction of the first hinge shaft 11 in this application is preferably the up-down direction, and is mainly used in the passenger compartment door of conventional vehicles.

[0035] The limit plate 30 is arranged on the first hinge seat 10, and a plurality of limit grooves 31 are arranged on the limit plate 30 at circumferential intervals along the first hinge axis 11; each limit groove 31 is for an opening position, and a limit groove 31 must be set corresponding to the closing and full opening of the vehicle respectively, and at least one limit groove 31 is set between the two limit grooves 31 to ensure that the vehicle has a middle limit, and the number of limit grooves 31 can be increased or decreased according to the needs of door limit.

[0036] The limit column 40 is arranged on the second hinge seat 20, and the limit column 40 is located on the circumference of the first hinge shaft 11. When the limit column 40 is embedded in the limit groove 31, the vehicle door will reach the opening corresponding to each limit groove 31. The groove wall of the limit groove 31 can limit the limit column 40 to fix the vehicle door at the opening to prevent the vehicle door from swinging due to gravity, wind force, etc., and the limit groove 31 is separated from the limit column 40 to cause the vehicle door to close.

[0037] The elastic unit 50 is used to make the limiting column 40 embedded in the limiting groove 31. When the door opening needs to be changed, the door can be pushed, and the groove wall of the limiting groove 31 will press the limiting column 40, thereby overcoming the elastic force of the elastic unit 50 to make the limiting column 40 disengage from the current limiting groove 31 and enter other limiting grooves 31 to complete the opening and closing action of the door.

[0038] like Figure 1 , 2 As shown in FIG. 3 , the limit plate 30 is an arc-shaped plate, and the curvature center of the limit plate 30 is the axis of the first hinge shaft 11. The car door itself is a device that rotates around the first hinge shaft 11, so the limit groove 31 also needs to be arranged around the first hinge shaft 11. Therefore, the limit plate 30 used to arrange the limit groove 31 is arranged along the circumference of the first hinge shaft 11 to ensure that the length of the groove bottom of each limit groove 31 and the axis of the first hinge shaft 11 are equal. If different limit forces are required for different limit grooves 31, the limit feature height and curvature between each two adjacent limit grooves 31 can also be adjusted. At the same time, by designing the limit plate 30 into an arc, the position of the car door when opening and closing can be controlled more accurately. The arc design allows the car door to move on a specific trajectory, ensuring that it accurately finds and locks in the desired position. The design of the arc-shaped limit plate 30 may cause the car door to move in a smooth arc during movement, rather than sudden or irregular movement. This can improve the operational stability of the door, making the opening and closing process smoother. The center of curvature being located at the axis of the first hinge axis 11 may mean that the force and pressure applied to the door during movement is more uniform. This helps to reduce friction and stress during the opening and closing process and improve the durability of the system.

[0039] like Figure 1 , 2 As shown in Figures 3 and 4, the limiting groove 31 is provided on the side of the limiting plate 30 close to the first hinge shaft 11, and the limiting column 40 is located on the side of the limiting plate 30 close to the first hinge shaft 11. The side of the limiting plate 30 close to the first hinge shaft 11 is an occupied space, and arranging the limiting column 40 in this space can avoid setting up additional space for setting up the limiting column 40, thereby reducing space occupation. Concentrating the limiting groove 31 and the limiting column 40 on one side of the limiting plate 30 helps to simplify system design, reduce manufacturing costs, and improve the reliability of the entire door system.

[0040] like Figure 1 , 2 As shown in Figures 3 and 4, one end of the limit plate 30 is hinged to the first hinge seat 10 via the second hinge shaft 12. That is, the limit plate 30 is swingably arranged on the first hinge seat 10, and can swing around the second hinge shaft 12. When the limit post 40 needs to be separated from the limit slot 31, the limit plate 30 can be swung away from the limit post 40, so that the limit post 40 is separated from the bottom of the current limit slot 31 to pass over the slot wall. When limiting is required, the limit plate 30 can swing toward the limit post 40, so that the limit post 40 is embedded in the limit slot 31.

[0041] like Figure 1 , 2 As shown in FIG. 3 , the elastic unit 50 is a tension spring, one end of which is connected to the end of the limiting plate 30 away from the second hinge shaft 12, and the other end of which is connected to the first hinge shaft 11. The tension spring is used to provide a fitting force for the limiting column 40 to be embedded in the limiting groove 31, so that the limiting column 40 will not be easily separated from the limiting groove 31.

[0042] like Figure 1 , 2 As shown in FIG. 3 , the groove walls between adjacent limiting grooves 31 have rounded transitions, and the groove bottoms of the limiting grooves 31 are arc-shaped groove structures. The rounded transition can ensure that when the door passes through adjacent limiting grooves 31 during the movement of the door, there will be no sharp turns or edge capture. This helps to achieve smoother door movement and improves the operational smoothness of the system. The rounded transition reduces the sharp edges between adjacent groove walls, helping to reduce friction and wear. This is beneficial to the durability and life of the system, especially when the door needs to be opened and closed frequently. The rounded design can reduce the stress concentration caused by the movement of the door and prevent the door from getting stuck or blocked during movement. This improves the reliability and safety of the door system.

[0043] like Figure 1 , 2 As shown in FIG. 3 , the limit column 40 is a cylindrical roller structure. The cylindrical roller structure can roll easily in the limit groove 31, so that the opening and closing movement of the door is smoother. This design helps to reduce friction and improve the operating efficiency of the door system. The rolling of the cylindrical roller structure in the limit groove 31 can provide more accurate positioning, ensuring that the door can be accurately locked in the desired position.

[0044] like Figure 1 , 2As shown in Figure 3, the width of the limit groove 31 adjacent to the second hinge shaft 12 is greater than the width of the limit groove 31. The limit groove 31 adjacent to the second hinge shaft 12 is the limit groove 31 corresponding to the closing of the car door, and the limit column 40 in the limit groove 31 can swing at a certain angle along the wider groove bottom. Since it is difficult to directly complete the action of pushing the car door when pulling the inner door handle, when opening the door, the occupants in the car usually unlock the car door and slightly open the car door to a certain angle to make the car door half-closed, and then change their posture to push the car door open. In this application, the width of the bottom of the limit groove 31 adjacent to the second hinge shaft 12 corresponds to the door opening angle from half-closed to fully closed.

[0045] like Figure 4 As shown, the utility model further provides a vehicle, including a door, wherein at least one door hinge is provided on a single door. A single door usually requires two hinges for articulation, but only one stopper is required, so one of the two hinges on the door in the present application is a common hinge and the other is a hinge with a stopper function in the above solution.

[0046] To sum up, the utility model proposes a door hinge and a vehicle. In the above scheme, a limiting device is arranged on the hinge, that is, an integrated device of the hinge and the limiter is formed. During installation, only the hinge needs to be installed, and only the original hinge space will be occupied. The device is easy to install and occupies little space, and can simultaneously complete the limitation of the opening of multiple doors.
