[0037] Embodiments of the present invention are described in detail below, examples of which 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0039] A door check device 10 for a vehicle according to an embodiment of a first aspect of the present invention will be described below with reference to the accompanying drawings.

[0040] like Figures 1 to 9As shown, a door limiter 10 for a vehicle according to an embodiment of the first aspect of the present invention comprises: a box body 1, a limit arm 2 and a limit mechanism 3, the box body 1 is suitable for being installed in a door of a vehicle, the limit arm 2 comprises a connecting rod 21 and a limit fitting portion 22, the connecting rod 21 is inserted into the box body 1, and one end of the connecting rod 21 located outside the box body 1 is suitable for being connected to a body side panel 200 of the vehicle, the limit fitting portion 22 is arranged on a portion of the connecting rod 21 located in the box body 1, the limit mechanism 3 is arranged in the box body 1 and is used to limit the movement of the limit fitting portion 22, the limit mechanism 3 is formed with a limit space 31 extending along a first direction e1, the first direction e1 is perpendicular to the up-down direction, the limit fitting portion 22 is slidably arranged in the limit space 31 along the first direction e1 and is rotatable relative to the limit mechanism 3, the limit fitting portion 22 can generate movement in the first direction e1 relative to the limit mechanism 3 and rotate around a rotation axis extending along the up-down direction and passing through its own center.

[0041] That is to say, the limit fitting part 22 is located in the box body 1 and is slidably matched with the limit space 31 formed by the limit mechanism 3. The limit space 31 can better limit the freedom of movement of the limit fitting part 22, so that the limit fitting part 22 can only move in the first direction e1 relative to the limit mechanism 3 and rotate around the rotation axis extending in the up and down directions and passing through its own center. Therefore, in the process of opening or closing the door, the movement trajectory of the limit fitting part 22 is a straight line extending along the first direction e1, and the connecting rod 21 can swing to a certain extent around the rotation axis of the limit fitting part 22, thereby forming an inward swing movement of the limit arm 2 relative to the box body 1.

[0042] Thus, the space required for the limit arm 2 to be occupied during the extension and retraction process can be reduced, thereby reducing the installation space occupied by the door stopper 10 inside the door. At the same time, the movement trajectory of the limit arm 2 inside the door is limited within the box body 1, which can avoid the movement trajectory of the limit arm 2 from interfering with other components in the door, such as the glass 40, and thus improve the reliability of the door stopper 10. In addition, only one through hole 111 is required to be provided on the box body 1 for the connecting rod 21 to pass through, thereby improving the sealing effect of the box body 1, thereby reducing the accumulation of dust and sand from the external space into the box body 1 to increase the movement resistance of the limit arm 2, thereby improving the dustproof performance of the door stopper 10.

[0043] The door limiter 10 for a vehicle according to the first aspect of the embodiment of the present invention can effectively reduce the space required by the limit arm 2 during the extension and retraction process, thereby reducing the installation space occupied by the door limiter 10 inside the door. At the same time, the movement trajectory of the limit arm 2 inside the door is restricted within the box body 1, which can avoid interference contact between the movement trajectory of the limit arm 2 and other components in the door, such as the glass 40, and is conducive to improving the reliability of the door limiter 10.

[0044] According to some embodiments of the present invention, a through hole 111 is formed on the box body 1 for the connecting rod 21 to be inserted into the limiting space 31, and the extension dimension of the through hole 111 in the second direction e2 is greater than the width dimension of the connecting rod 21 in the second direction e2, and the second direction e2 is perpendicular to the first direction e1 and the up-down direction. Among them, the width dimension of the connecting rod 21 in the second direction e2 is the maximum distance between the two side edges of the cross section of the connecting rod 21 in the second direction e2, and when the cross section of the connecting rod 21 is circular, the width dimension of the connecting rod 21 in the second direction e2 is the diameter of the circle. For the convenience of description, the end of the connecting rod 21 located inside the box body 1 is defined as the first end, and the end of the connecting rod 21 located outside the box body 1 is defined as the second end.

[0045] That is, the first end of the connecting rod 21 is inserted into the limiting space 31 in the box body 1 through the through hole 111, and since the extension dimension of the through hole 111 in the second direction e2 is greater than the width dimension of the connecting rod 21 in the second direction e2, the through hole 111 can provide a certain activity space for the connecting rod 21 in the second direction e2, that is, the connecting rod 21 can move in the through hole 111 along the second direction e2, thereby ensuring that the through hole 111 can better adapt to the swing of the connecting rod 21 relative to the box body 1. Specifically, the through hole 111 is provided on the side wall of the box body 1 in the first direction e1.

[0046] In a specific example, the connecting rod 21 is a round rod, so that the contact area between the connecting rod 21 and the inner circumference of the through hole 111 can be reduced, and the friction between the connecting rod 21 and the box body 1 can be reduced. It should be noted that this is only an example of one shape of the connecting rod 21, and it is not a limitation on the shape of the connecting rod 21. In another specific example, the connecting rod 21 can also be formed as a square rod, etc., and the connecting rod 21 and the through hole 111 can have a certain swing space in the through hole 111 along the second direction e2.

[0047] In addition, it should be noted that the extension dimension of the through hole 111 in the second direction e2 is smaller than the width dimension of the limiting fitting portion 22 in the second direction e2 to prevent the limiting fitting portion 22 from coming out of the box body 1, thereby preventing the limiting arm 2 from being separated from the box body 1. In a specific example, the connecting rod 21 and the limiting fitting portion 22 are formed independently, so during the assembly process of the door limiter 10, the first end of the connecting rod 21 can be inserted into the box body 1 through the through hole 111, and then the limiting fitting portion 22 can be installed and fixed on the first end of the connecting rod 21, which can reduce the difficulty of assembling the limiting arm 2 and the box body 1.

[0048] According to some embodiments of the present invention, the position-limiting matching portion 22 is fixedly connected to the connecting rod 21. That is, the relative position between the position-limiting matching portion 22 and the connecting rod 21 remains fixed, and the position-limiting matching portion 22 cannot generate relative movement relative to the connecting rod 21. Thus, the connection structure between the position-limiting matching portion 22 and the connecting rod 21 can be simplified, such as being connected by a relatively simple connection method such as welding or screw connection, so as to reduce the difficulty of producing the position-limiting arm 2.

[0049] According to some embodiments of the present invention, the position-limiting matching portion 22 is located at one end of the connecting rod 21 inserted into the box body 1. In other words, the position-limiting matching portion 22 is located at the first end of the connecting rod 21, so that in the process of opening or closing the door, the axis of the swing of the connecting rod 21 relative to the box body 1 is located at the first end of the connecting rod 21, thereby avoiding occupying the space on the side of the position-limiting matching portion 22 away from the second end during the swinging process of the connecting rod 21, thereby better reducing the space required to be occupied by the limit arm 2 during the extension and retraction process, so as to reduce the installation space occupied by the door limiter 10 inside the door.

[0050] According to some embodiments of the present invention, the position-limiting mating portion 22 is spherical. The space occupied by the spherical structure remains unchanged when it rotates around an axis passing through its own center. Therefore, by setting the position-limiting mating portion 22 to be spherical, it is possible to avoid the position-limiting mating portion 22 occupying additional space when rotating. In addition, the position-limiting mating portion 22 of the spherical structure can reduce the friction between the position-limiting mechanism 3, thereby reducing the resistance of the position-limiting mating portion 22 to slide relative to the position-limiting mechanism 3, so as to improve the smoothness of the use of the door stopper 10.

[0051] It should be noted that this is only an example of the shape of one of the limit fitting parts 22, in order to facilitate the understanding of the cooperation between the limit fitting part 22 and the limit mechanism 3, and it is not a limitation on the shape of the limit fitting part 22. The shape of the limit fitting part 22 only needs to satisfy the requirement that the space occupied by the limit fitting part 22 remains unchanged when it rotates around an axis extending in the up-down direction and passing through its own center. For example, the limit fitting part 22 may be cylindrical, olive-shaped, biconical, etc. extending in the up-down direction, and they will not be described one by one here.

[0052] According to some embodiments of the present invention, the limiting mechanism 3 includes two groups of limiting components 32 distributed on the upper and lower sides of the limiting matching part 22, each group of limiting components 32 includes a limiting body 321 and an elastic member 322, the limiting body 321 extends along the first direction e1 and contacts and cooperates with the limiting matching part 22, the two limiting bodies 321 jointly define the limiting space 31, and the elastic member 322 is arranged between the limiting body 321 and the box body 1 and is used to drive the limiting body 321 to approach the limiting matching part 22. That is to say, the position-limiting mating part 22 is located between the two position-limiting bodies 321, and the elastic member 322 of the position-limiting assembly 32 located on the upper side of the position-limiting mating part 22 applies a downward thrust to the corresponding position-limiting body 321, and the elastic member 322 of the position-limiting assembly 32 located on the lower side of the position-limiting mating part 22 applies an upward thrust to the corresponding position-limiting body 321, so that the two position-limiting bodies 321 can clamp the position-limiting mating part 22 from both sides in the up-down direction through the elastic members 322 of the two groups of position-limiting assemblies 32. Thus, the two groups of position-limiting assemblies 32 can evenly apply a position-limiting force to the position-limiting mating part 22 from both sides in the up-down direction, so that the position-limiting mating part 22 can be better maintained in the up-down direction, and the position-limiting mating part 22 can be prevented from being offset in the up-down direction to affect the extraction or insertion of the connecting rod 21, which is conducive to improving the reliability of the door stopper 10.

[0053] In a specific example, the side of the limiting body 321 facing the limiting fitting part 22 is formed as a limiting track, and the limiting tracks of the two limiting bodies 321 jointly define the limiting space 31. The cross-section of the limiting track in the first direction e1 is a concave arc, and the limiting track matches the shape of the limiting fitting part 22, so that the limiting track can better limit the freedom of movement of the limiting fitting part 22 in the second direction e2, while ensuring that the limiting fitting part 22 can slide along the first direction e1 relative to the limiting body 321.

[0054] According to some embodiments of the present invention, a plurality of limiting grooves 3211 arranged along the first direction e1 are formed on the side of the limiting body 321 facing the limiting matching part 22, and the limiting grooves 3211 are used to accommodate the ends of the limiting matching part 22 in the up-down direction. That is to say, when the limiting matching part 22 is located in the limiting grooves 3211, the limiting grooves 3211 have a certain limiting effect on the limiting matching part 22 to limit the sliding of the limiting matching part 22 along the first direction e1 relative to the limiting body 321. Therefore, in the process of opening or closing the door, when the limiting matching part 22 moves into the limiting grooves 3211, the limiting grooves 3211 limit the freedom of movement of the limiting matching part 22 in the first direction e1, so that the door can be suspended. In addition, the plurality of limiting grooves 3211 are arranged along the first direction e1, so when the limiting matching part 22 is located in different limiting grooves 3211, the door can be suspended at different openings, which is highly flexible. It should be noted that the number of the limiting grooves 3211 of the two limiting bodies 321 is the same and corresponds one to one, and the corresponding two limiting grooves 3211 are relatively arranged in the up and down directions, so that the limiting matching part 22 can be limited by the limiting grooves 3211 of the two limiting bodies 321.

[0055] In a specific example, the door limiter 10 has at least a first gear, a second gear and a third gear. Each limit body 321 has three limit grooves 3211 arranged at intervals along the first direction e1 on the side facing the limit matching part 22. When the limit matching part 22 is located in the three limit grooves 3211, it corresponds to the first gear, the second gear and the third gear respectively, so that the door can at least hover at three different openings.

[0056] According to some embodiments of the present invention, at least one of the box body 1 and the stopper 321 is provided with a mounting groove 3212 for accommodating the end of the elastic member 322. That is, when the elastic member 322 is assembled, the elastic member 322 is aligned with the mounting groove 3212 and inserted. Thus, the difficulty of positioning and installing the elastic member 322 can be reduced, which is conducive to improving the assembly efficiency of the door stopper 10. At the same time, the freedom of movement of the elastic member 322 can be better limited by the mounting groove 3212, so that the stability of the elastic member 322 after installation can be improved.

[0057] According to some embodiments of the present invention, each group of limiting components 32 includes a plurality of elastic members 322. That is, each group of limiting components 32 applies a force to the corresponding limiting body 321 to move toward the limiting matching portion 22 through the plurality of elastic members 322, and at the same time, the thrust of the limiting matching portion 22 acting on the limiting body 321 can be distributed on the corresponding plurality of elastic members 322. Thus, the force on each elastic member 322 can be reduced, so that the elastic force attenuation of the elastic member 322 can be reduced, so as to ensure the limiting force of the limiting component 32 on the limiting matching portion 22.

[0058] According to some embodiments of the present invention, the multiple elastic members 322 of each group of the limiting assembly 32 are arranged at intervals along the first direction e1. In other words, the arrangement direction of the multiple elastic members 322 is the same as the extension direction of the limiting body 321. In the first direction e1, the multiple elastic members 322 can provide support forces for multiple positions of the limiting body 321, thereby ensuring the uniformity of the multiple elastic members 322 supporting the limiting body 321 in the first direction e1. Therefore, when the limiting fitting part 22 moves along the limiting body 321 in the first direction e1, the limiting body 321 can be pushed by the elastic members 322 at different positions in the first direction e1 to apply a limiting force to the limiting fitting part 22, thereby preventing the limiting fitting part 22 from shaking in the up and down directions during the movement along the first direction e1, so as to improve the stability of the door stopper 10.

[0059] According to some embodiments of the present invention, the box body 1 includes a box body 11 and a cover body 12 that are detachably connected, and the cover body 12 is connected to one side of the box body 11 in the up-down direction. Therefore, by providing a detachably connected box body 11 and a cover body 12, the difficulty of installing the limiting mechanism 3 into the box body 1 can be reduced, which is conducive to improving the assembly efficiency of the door limiter 10. Specifically, the box body 11 has a cavity open to the cover body 12, the limiting mechanism 3 is installed in the cavity of the box body 11, and the cover body 12 is used to close the opening of the cavity of the box body 11.

[0060] For the convenience of description, the limiting body 321 and the elastic member 322 located on the upper side of the limiting matching part 22 are defined as the first limiting body and the first elastic member respectively, and the limiting body 321 and the elastic member 322 located on the lower side of the limiting matching part 22 are defined as the second limiting body and the second elastic member respectively, and the through hole 111 is provided on the box body 11, and the upper side surface of the first limiting body and the lower side surface of the second limiting body are both formed with a plurality of mounting grooves 3212 arranged along the first direction e1, and at the same time, the inner bottom wall of the box body 11 and the side surface of the cover body 12 opposite to the first limiting body are both formed with mounting grooves 3212 arranged along the first direction e1, wherein the inner bottom wall of the box body 11 refers to the inner wall surface opposite to the box body 11 and the cover body 12 in the up and down directions. Therefore, when the limiting mechanism 3 is installed to the box body 1 During the process, the box body 11 can be inverted first, that is, the opening of the box body 11 is facing upward, and then one end of the multiple first elastic members is inserted into the installation groove 3212 of the inner bottom wall of the box body 11, and then the first limiting body is placed in the box body 11 so that the other ends of the multiple first elastic members are inserted into the multiple installation grooves 3212 of the first limiting body, and the first end of the connecting rod 21 is inserted into the box body 11 through the through hole 111, and the limiting matching part 22 is installed on the first end, and then the second limiting body is installed in the box body 11, and one ends of the multiple second elastic members are aligned with the multiple installation grooves 3212 of the second limiting body and inserted respectively, and finally the cover body 12 is installed on the box body 11, and the other ends of the multiple second elastic members are respectively located in the multiple installation grooves 3212 of the cover body 12.

[0061] According to some embodiments of the present invention, the door stopper 10 further includes a fixing seat 4, which is suitable for connecting to the vehicle body side 200, and one end of the connecting rod 21 located outside the box body 1 is rotatably connected to the fixing seat 4. That is, the door stopper 10 is connected to the vehicle body side 200 through the fixing seat 4, which is conducive to improving the stability of the connection between the door stopper 10 and the vehicle body side 200. Among them, the second end of the connecting rod 21 is hinged to the fixing seat 4, so as to ensure that the connecting rod 21 can rotate relative to the vehicle body side 200 together with the vehicle door.

[0062] In a specific example, the second end of the connecting rod 21 is connected to the fixing seat 4 through a fixing rivet 5. The fixing rivet 5 is arranged on the fixing seat 4. The connecting rod 21 can rotate relative to the fixing rivet 5. The connecting rod 21 extends in the up and down direction relative to the rotation axis of the fixing rivet 5.

[0063] The vehicle door assembly 100 according to a second embodiment of the present invention will be described below with reference to the accompanying drawings.

[0064] The vehicle door assembly 100 according to the second embodiment of the present invention comprises: a vehicle door stopper 10, a vehicle door inner panel 20 and a reinforcing connecting plate 30. The vehicle door stopper 10 is arranged on the inner side of the vehicle door inner panel 20, and the reinforcing connecting plate 30 is connected to the box body 1 and the vehicle door inner panel 20 at the same time. That is to say, the vehicle door stopper 10 is directly connected to the vehicle door inner panel 20 and is also connected to the vehicle door inner panel 20 through the reinforcing connecting plate 30. Therefore, the connection position of the vehicle door stopper 10 and the vehicle door inner panel 20 can be increased by the reinforcing connecting plate 30, so that the installation position of the vehicle door stopper 10 can be better maintained by the reinforcing connecting plate 30, so as to ensure that the vehicle door stopper 10 is firmly installed in the vehicle door.

[0065] According to the vehicle door assembly 100 of the second embodiment of the present invention, the installation space occupied by the vehicle door limiter 10 inside the vehicle door can be reduced. The vehicle door limiter 10 is arranged on the inner side of the vehicle door inner panel 20, and the reinforcing connecting plate 30 is connected to the box body 1 and the vehicle door inner panel 20 at the same time. The connection position of the vehicle door limiter 10 and the vehicle door inner panel 20 can be better increased by reinforcing the connecting plate 30, so that the installation position of the vehicle door limiter 10 can be better maintained by reinforcing the connecting plate 30 to ensure that the vehicle door limiter 10 is firmly installed in the vehicle door.
