[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] Reference below Figures 1-7 The vehicle door stopper 100 according to an embodiment of the present invention is described as follows. Figures 6-7 As shown, the door stopper 100 can be mounted on a vehicle. Specifically, the door stopper 100 is mounted on a door sheet metal 200 of the vehicle to limit the door.

[0040] like Figures 1-4 As shown, the door limiter 100 according to the embodiment of the utility model includes: a shell 1 and an arm 2, the arm 2 is inserted into the shell 1; a plurality of sliders 3 and a plurality of elastic members 4, the plurality of sliders 3 and the plurality of elastic members 4 are all arranged in the shell 1, the plurality of sliders 3 are arranged around the arm 2, and each slider 3 is provided with a rotatable cylinder 5, the corresponding slider 3 is movable along the arrangement direction of the corresponding slider 3 and the arm 2, and the side of each slider 3 away from the arm 2 is provided with an elastic member 4, and the elastic member 4 is compressed to make the peripheral wall of the corresponding cylinder 5 abut against the arm 2.

[0041] Among them, the door limiter 100 includes a housing 1, an arm rod 2, a plurality of sliders 3 and a plurality of elastic members 4. The housing 1 may include a bottom plate 13 and a cover 12. As some embodiments of the present application, the bottom plate 13 and the cover 12 may be connected by rivets to form the housing 1. As some embodiments of the present application, the bottom plate 13 and the cover 12 may be connected by snap connection to form the housing 1. The bottom plate 13 and the cover 12 jointly define an installation space, and both the slider 3 and the elastic member 4 are arranged in the installation space. Along the first direction, that is Figure 1 the X direction in [[]], one end of the cover 12 is open, and a through hole is formed at the other end of the cover 12. The bottom plate 13 is formed with a through hole. The size of the through hole of the cover 12 and the size of the through hole of the bottom plate 13 are both adapted to the size of the arm rod 2, so that the arm rod 2 can be assembled in the through holes of the cover 12 and the bottom plate 13, thereby achieving the effect that the arm rod 2 passes through the housing 1. The arm rod 2 may include a metal skeleton 21 and plastic coating 22. As some embodiments of the present application, the metal skeleton 21 may be configured as a steel core. By covering the steel core with the plastic coating 22, the risk of rigid impact between the steel core and the housing 1 can be reduced, and the risk of rigid impact between the steel core and other structures in the housing 1 can be reduced, thereby improving the use experience of the door limiter 100.

[0042] As some embodiments of the present application, both the slider 3 and the elastic member 4 may be provided in two, three, four or more. As some embodiments of the present application, the slider 3 may be made of plastic material, which is beneficial to reducing the production cost of the door limiter 100 and is also beneficial to the lightweight design of the vehicle. As some embodiments of the present application, the slider 3 may be made of metal material, which is beneficial to improving the strength of the slider 3, thereby improving the service life of the door limiter 100. The plurality of sliders 3 can be assembled into the cover 12 from the open end of the cover 12. The bottom plate 13 is used to cover the open end of the cover 12, so that the plurality of sliders 3 are arranged in the housing 1, reducing the risk that the sliders 3 move out of the housing 1 through the open end of the cover 12, which is beneficial to improving the structural reliability of the door limiter 100, and thus beneficial to the smooth realization of the limiting function of the door limiter 100.

[0043] As some embodiments of the present application, the slider 3 is provided in two, and the two sliders 3 are along the second direction, that is Figure 1The Y direction therein is arranged on both sides of the arm 2. The second direction is perpendicular to the first direction, that is to say, the X direction and the Y direction are perpendicular. As some embodiments of the present application, four sliders 3 are provided, and the four sliders 3 are arranged around the arm 2 at uniform intervals. As some embodiments of the present application, the cylinder 5 can be snap-connected to the slider 3. As some embodiments of the present application, the cylinder 5 can be pivotally connected to the slider 3. Such an arrangement enables each slider 3 to be provided with a rollable cylinder 5, facilitating the rolling fit between the slider 3 and the arm 2, which is beneficial to reducing the risk of damage to the plastic coating 22 or noise caused by direct friction between the slider 3 and the arm 2, thereby improving the quality of the door limiter 100.

[0044] Furthermore, compared with each slider 3 being provided with a ball, each slider 3 being provided with a rollable cylinder 5 can reduce the production cost of the door limiter 100, and is also beneficial to increasing the force-bearing area of the arm 2, enabling the arm 2 to move smoothly, thereby enhancing the user experience of the door limiter 100, and also reducing the risk of damage to the plastic coating 22 caused by stress concentration on the arm 2, and further improving the service life of the door limiter 100.

[0045] As some embodiments of the present application, the arm 2 is arranged with different gears so that the door can stop rotating at different gears. As some embodiments of the present application, along the length direction of the arm 2, that is Figure 1 the X direction therein, the gears of the arm 2 can be configured to form different grooves at different positions. Along the arrangement direction of the corresponding slider 3 and the arm 2, the slider 3 can reciprocate so that the cylinder 5 on the slider 3 can be snap-connected into the grooves of different gears of the arm 2, thereby enabling the user to adjust the opening degree of the door according to the usage needs, which is beneficial to enhancing the user experience.

[0046] As some embodiments of the present application, the elastic member 4 can be configured as a metal spring. As some embodiments of the present application, the elastic member 4 can be configured as a metal spring sheet. The present application takes the elastic member 4 being configured as a metal spring as an example for illustration. By configuring the elastic member 4 as a metal spring, the risk of aging of the elastic member 4 can be reduced, which is beneficial to further improving the quality of the door limiter 100. Moreover, since the size of the metal spring is small, such an arrangement is beneficial to reducing the size of the door limiter 100, thereby being beneficial to reducing the occupied space of the door limiter 100 for the vehicle, and further being beneficial to the layout of the vehicle.

[0047] A plurality of elastic members 4 are all arranged in the installation space of the housing 1, and the elastic members 4 are all arranged on the side of each slider 3 facing away from the arm 2. Such an arrangement enables the elastic member 4 to be compressed between the housing 1 and the slider 3, so that the elastic member 4 can always apply a pressure to the side of the slider 3 facing away from the arm 2, so that the peripheral wall of the corresponding cylinder 5 on the corresponding slider 3 can be reliably abutted against the arm 2.

[0048] Specifically, the door limiter 100 may further include a bracket 6, and the bracket 6 is connected to one end of the arm rod 2. In some embodiments of the present application, the bracket 6 and the arm rod 2 may be connected by riveting. In some embodiments of the present application, the bracket 6 and the arm rod 2 may be connected by bolts. By assembling the bracket 6 on the vehicle side panel, one end of the arm rod 2 can be assembled on the vehicle side panel through the bracket 6. In some embodiments of the present application, the housing 1 may be formed with a connecting portion 11. In some embodiments of the present application, the connecting portion 11 and the door sheet metal 200 may be connected by screws. In some embodiments of the present application, the connecting portion 11 and the door sheet metal 200 may be connected by bolts, so that the housing 1 is fixedly connected to the door sheet metal 200, thereby realizing the assembly of the door limiter 100 between the vehicle side panel and the door sheet metal 200.

[0049] When the door needs to be rotated to the target position, the door rotates around the axis of the door hinge. At this time, the arm rod 2 applies pressure to the slider 3 so that the corresponding elastic member 4 is compressed. And the slider 3 drives the cylinder 5 to roll and slide on the arm rod 2, so that the cylinder 5 moves to the gear groove corresponding to the target position. At this time, the compressed elastic member 4 applies pressure to the slider 3, so that the cylinder 5 is clamped in the corresponding groove, thereby realizing the effect of limiting the door at the target position.

[0050] Furthermore, one end of the arm rod 2 is connected with a bracket 6, and a buffer block 7 may be arranged at the other end of the arm rod 2. When the opening degree of the door reaches the maximum, the buffer block 7 contacts the housing 1, playing a buffering role for the door, reducing the risk of damage to the door limiter 100 caused by excessive opening force of the door, and being beneficial to further improving the service life of the door limiter 100.

[0051] Thus, by arranging a plurality of sliders 3 around the arm rod 2, and each slider 3 is provided with a rollable cylinder 5, the cylinder 5 and the arm rod 2 can be in rolling fit, reducing the risk of damage to the door limiter 100 caused by long-term sliding friction between the cylinder 5 and the arm rod 2, thereby improving the use reliability of the door limiter 100. And the rolling fit between the cylinder 5 and the arm rod 2 can effectively improve the use feeling of the door limiter 100, being beneficial to enhancing the user's vehicle use experience, and further improving the market competitiveness of the vehicle.

[0052] In some embodiments of the present invention, as Figure 1 shown, at least two sliders 3 are arranged opposite to each other.

[0053] Among them, by setting the slider 3 to at least two, the two sliders 3 can be arranged oppositely on both sides of the arm 2, which is beneficial for the corresponding cylinders 5 on the two sliders 3 to roll and slide on both sides of the arm 2. Compared with setting the slider 3 to one, it is beneficial for both sides of the arm 2 to be evenly stressed, improving the stress balance of the arm 2, thereby reducing the risk of damage to the plastic coating 22 caused by stress concentration on one side of the arm 2, being beneficial for improving the service life of the arm 2, and further improving the service life of the door limiter 100.

[0054] In some embodiments of the present invention, as Figure 1 shown, a plurality of sliders 3 and a plurality of elastic members 4 correspond to each other one by one.

[0055] Among them, a plurality of sliders 3 and a plurality of elastic members 4 correspond to each other one by one, that is to say, one slider 3 corresponds to one elastic member 4. Such a setting can reduce the risk of increased production costs caused by one slider 3 corresponding to a plurality of elastic members 4.

[0056] In some embodiments of the present invention, as Figure 1 shown, along the arrangement direction of the corresponding slider 3 and the arm 2, both ends of the elastic member 4 are respectively in contact with the housing 1 and the corresponding slider 3.

[0057] Among them, along the arrangement direction of the corresponding slider 3 and the arm 2, both ends of the elastic member 4 are respectively in contact with the housing 1 and the corresponding slider 3, so that the elastic member 4 is compressed between the housing 1 and the corresponding slider 3. Since the housing 1 is fixedly arranged on the door sheet metal 200 and the position of the housing 1 remains unchanged, by respectively contacting both ends of the elastic member 4 with the housing 1 and the corresponding slider 3, the elastic member 4 can always apply pressure to the slider 3, so that the peripheral wall of the corresponding cylinder 5 on the corresponding slider 3 can always be in contact with the arm 2, which is beneficial for limiting the cylinder 5 in the grooves at different positions on the arm 2, and thus is beneficial for further realizing the limiting function of the door limiter 100.

[0058] In some embodiments of the present invention, as Figure 1 shown, a limiting post 34 is formed on the side of the slider 3 facing away from the arm 2, and the elastic member 4 is sleeved on the limiting post 34.

[0059] Among them, the slider 3 can form a limiting post 34, and the limiting post 34 is formed on the side of the slider 3 facing away from the arm 2. Such a setting can make the position of the limiting post 34 reasonably arranged, which is beneficial for the elastic member 4 to be smoothly sleeved on the limiting post 34. By forming a limiting post 34 on the side of the slider 3 facing away from the arm 2, the limiting post 34 can reliably limit the elastic member 4. When the elastic member 4 is compressed, the risk of bending of the elastic member 4 can be reduced, which is beneficial for the realization of the function of the elastic member 4.

[0060] In some embodiments of the present invention, as Figure 5As shown, on the other side of the slider 3 facing the arm lever 2, a mounting groove 31 is formed, and a part of the cylinder 5 is assembled in the mounting groove 31.

[0061] Among them, the slider 3 can also form a mounting groove 31. The mounting groove 31 is recessed towards the inside of the slider 3 so that the slider 3 can provide an assembly position for the cylinder 5. The mounting groove 31 is open towards the arm lever 2, and a part of the cylinder 5 can be assembled in the mounting groove 31 through the open end of the mounting groove 31. As some embodiments of the present application, the cylinder 5 can be snap-connected to the slider 3 so that a part of the cylinder 5 is snap-connected in the mounting groove 31. As some embodiments of the present application, the cylinder 5 can be pivotally connected to the slider 3 so that the cylinder 5 can roll in the mounting groove 31.

[0062] The mounting groove 31 is formed on the other side of the slider 3 facing the arm lever 2, and a part of the cylinder 5 is assembled in the mounting groove 31. Such a setting can make another part of the cylinder 5 protrude from the mounting groove 31, facilitating the part of the cylinder 5 protruding from the mounting groove 31 to abut against the arm lever 2, reducing the risk of direct friction between the slider 3 and the arm lever 2 caused by the entire cylinder 5 being assembled in the mounting groove 31, thereby reducing the risk of damage to the plastic coating 22 of the arm lever 2 caused by direct friction between the slider 3 and the arm lever 2, and also reducing the risk of noise generation in the door limiter 100 caused by direct friction between the slider 3 and the arm lever 2, thereby improving the quality of the door limiter 100.

[0063] In some embodiments of the present utility model, as Figure 5 shown, a limiting structure 32 is formed on the other side surface of the slider 3 facing the arm lever 2. The limiting structure 32 abuts against the corresponding cylinder 5 to limit the cylinder 5 from moving out of the mounting groove 31.

[0064] Among them, a limiting structure 32 is formed on the surface of the slider 3. The limiting structure 32 is formed on the other side surface of the slider 3 facing the arm lever 2. As some embodiments of the present application, the limiting structure 32 and the slider 3 can be integrally formed. As some embodiments of the present application, the limiting structure 32 and the slider 3 can be processed and formed separately and then heat-melted and connected. The present application takes the integral formation of the limiting structure 32 and the slider 3 as an example for illustration. That is to say, the limiting structure 32 and the slider 3 are constructed as an integrally formed part. The integrally formed part has good structural strength. By integrally forming the limiting structure 32 and the slider 3, the connection reliability between the limiting structure 32 and the slider 3 can be improved, the probability of fracture at the connection between the limiting structure 32 and the slider 3 can be reduced, thereby reducing the risk of the cylinder 5 falling out of the mounting groove 31 due to the fracture of the limiting structure 32, and further improving the structural stability and service life of the door limiter 100. Moreover, by constructing the limiting structure 32 and the slider 3 as an integrally formed part, the number of molds can be reduced, thereby further reducing the production cost of the door limiter 100.

[0065] The limiting structures 32 may be, but are not limited to, two, three, four or more, which is beneficial to improving the limiting reliability of the limiting structures 32. The multiple limiting structures 32 may be arranged circumferentially along the open end of the installation groove 31, and the limiting structures 32 partially block the open end of the installation groove 31, so that the slider 3 can be clamped and connected with the corresponding cylinder 5. Compared with other assembly methods, such an arrangement can reduce the assembly difficulty between the slider 3 and the corresponding cylinder 5, thereby reducing the assembly difficulty of the car door stopper 100 and improving the assembly efficiency of the car door stopper 100. The limiting structure 32 abuts against the corresponding cylinder 5 so that the limiting structure 32 can limit the cylinder 5 from moving out of the installation groove 31, which is beneficial to the reliable clamping of the cylinder 5 in the installation groove 31, so that a part of the cylinder 5 is reliably assembled in the installation groove 31, and further reduces the risk of the cylinder 5 falling from the open end of the installation groove 31 and causing direct friction between the slider 3 and the arm rod 2.

[0066] In some embodiments of the present utility model, such as Figure 5 shown, the slider 3 is formed with a first guiding portion 33, and the housing 1 is formed with a second guiding portion (not shown in the figure). The first guiding portion 33 and the second guiding portion are in guiding cooperation to guide the corresponding slider 3 in the arrangement direction of the corresponding slider 3 and the arm rod 2.

[0067] Among them, the slider 3 may be formed with a first guiding portion 33, and the housing 1 may be formed with a second guiding portion. The sizes and shapes of the first guiding portion 33 and the second guiding portion are adapted so that the first guiding portion 33 and the second guiding portion can be in guiding cooperation. Along the arrangement direction of the corresponding slider 3 and the arm rod 2, the first guiding portion 33 and the second guiding portion are in guiding cooperation, which can achieve the effect of guiding the corresponding slider 3, is beneficial to the movement of the corresponding slider 3 along the arrangement direction of the corresponding slider 3 and the arm rod 2, and reduces the risk that the moving direction of the corresponding slider 3 deviates from the preset direction. When the cylinder 5 is in rolling cooperation with the arm rod 2, it can also reduce the vibration risk of the corresponding slider 3 in the housing 1, thereby reducing the risk of noise generated by the car door stopper 100 due to the vibration of the housing 1 and the slider 3, and further improving the quality of the car door stopper 100.

[0068] In some embodiments of the present utility model, such as Figure 5 shown, one of the first guiding portion 33 and the second guiding portion is a sliding groove, and the other of the first guiding portion 33 and the second guiding portion is a sliding table, and the sliding table is assembled in the sliding groove.

[0069] Among them, in some embodiments of the present application, the first guiding portion 33 is configured as a sliding groove, and the second guiding portion is configured as a sliding table. In some embodiments of the present application, the first guiding portion 33 is configured as a sliding table, and the second guiding portion is configured as a sliding groove. By configuring one of the first guiding portion 33 and the second guiding portion as a sliding groove and the other as a sliding table, and assembling the sliding table into the sliding groove, the guiding cooperation effect of the first guiding portion 33 and the second guiding portion can be achieved, which is beneficial to the first guiding portion 33 and the second guiding portion guiding the corresponding slider 3 in the arrangement direction of the corresponding slider 3 and the arm rod 2.

[0070] Compared with the first guiding portion 33 and the second guiding portion being configured in other forms, configuring the first guiding portion 33 and the second guiding portion as a sliding groove and a sliding table structure can improve the guiding reliability of the first guiding portion 33 and the second guiding portion, reduce the damage risk of any one of the first guiding portion 33 and the second guiding portion, thereby improving the structural reliability of the door limiter 100, and further improving the quality of the door limiter 100.

[0071] According to the vehicle of the embodiment of the present invention, it includes the door limiter 100 of the above embodiment. By arranging a plurality of sliders 3 around the arm rod 2, and each slider 3 is provided with a rollable cylinder 5, the cylinder 5 and the arm rod 2 can be in rolling cooperation, reducing the damage risk of the door limiter 100 caused by the long-term sliding friction between the cylinder 5 and the arm rod 2, thereby improving the use reliability of the door limiter 100. Moreover, the rolling cooperation between the cylinder 5 and the arm rod 2 can effectively improve the use feeling of the door limiter 100, which is beneficial to improving the user's vehicle use experience, and further improving the market competitiveness of the vehicle.
