[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] The following is for reference. Figures 1-7 The present invention describes a dustproof device 10 for a door limiter 20 according to an embodiment of the present invention. The dustproof device 10 can be installed in a door limiter system 100, which can be installed in a vehicle 1.

[0022] According to the first aspect of the present invention, a dustproof device 10 for a door limiter 20 is provided, such as Figures 1-7 As shown, the dustproof device 10 for the door limiter 20 may include: a dustproof body 11, the dustproof body 11 defining a mounting groove 111 with one end open, the mounting groove 111 for mounting the door limiter 20, the dustproof body 11 having a first groove sidewall 112, the first groove sidewall 112 forming a drain port 113, the drain port 113 being adapted to allow liquid in the mounting groove 111 to drain out of the dustproof body 11.

[0023] It should be noted that existing dustproof devices for door limiters are ineffective at preventing dust from entering the door limiters. Dust, sand, and other contaminants can easily adhere to the door limiters, and water can easily accumulate inside the dustproof devices, which can easily lead to problems such as wear and corrosion of the door limiters.

[0024] Based on this, this application provides a dustproof device 10 for a door limiter 20. The dustproof device 10 may include a dustproof body 11, which may define a mounting groove 111 with one open end. The mounting groove 111 may have an open end. When the dustproof device 10 and the door limiter 20 are used together, and the door limiter 20 is installed on the vehicle 1, along the depth direction of the mounting groove 111, the open end of the mounting groove 111 may be located on the side of the dustproof body 11 facing the door 200 of the vehicle 1. The mounting groove 111 can be used to install the door limiter 20, at least a portion of the door limiter 20 may be located within the mounting groove 111, the door limiter 20 may pass through the open end of the mounting groove 111, and the door limiter 20 may be connected to the body and door 200 of the vehicle 1. The dustproof body 11 can cover at least a portion of the door limiter 20. The dustproof body 11 can protect the door limiter 20 and reduce the probability of dust, sand and other pollutants adhering to the door limiter 20. The dustproof device 10 can prevent dust from entering the door limiter 20, which can reduce the mechanical wear of the door limiter 20 and extend its service life.

[0025] The dustproof body 11 may have a first groove sidewall 112, and the first groove sidewall 112 may have a drain port 113. The drain port 113 may communicate with the mounting groove 111, and the liquid in the mounting groove 111 may be discharged from the dustproof body 11 through the drain port 113. When the vehicle 1 is in a humid environment, the liquid in the humid environment may enter the mounting groove 111 through the open end of the mounting groove 111, or when the vehicle 1 is in a low temperature environment, condensation may form in the mounting groove 111. That is, under certain working conditions, there will be liquid in the mounting groove 111. By setting the drain port 113, it is beneficial to allow the liquid in the mounting groove 111 to be discharged from the dustproof body 11. The dustproof device 10 can waterproof the door limiter 20, which helps to reduce the probability of corrosion of the door limiter 20 and extends the service life of the door limiter 20.

[0026] In this embodiment, the dustproof device 10 can protect the door limiter 20 from dust and water, which helps reduce the probability of wear and corrosion of the door limiter 20 and extends its service life.

[0027] As an example, the door limiter 20 can be used to control the opening and closing angle of the door 200. The door limiter 20 may include a limiter bracket 21, a limiter housing 22, and a limiter main arm 23. One end of the limiter main arm 23 can be hinged to the limiter bracket 21, and the limiter main arm 23 can rotate relative to the limiter bracket 21. The other end of the limiter main arm 23 away from the limiter bracket 21 can be located in the mounting groove 111. The limiter bracket 21 can be connected to the vehicle body of the vehicle 1 by bolts. The limiter housing 22 can be connected to the door 200 of the vehicle 1 by bolts.

[0028] In some embodiments of this utility model, such as Figure 4 and Figure 7 As shown, there are two first groove sidewalls 112, which are opposite to each other and spaced apart, and the mounting groove 111 is located between the two first groove sidewalls 112.

[0029] There can be two first groove sidewalls 112, which can be arranged opposite to each other or spaced apart. The mounting groove 111 can be located between the two first groove sidewalls 112. When the dustproof device 10 is installed on the vehicle 1, the two first groove sidewalls 112 can be arranged opposite to each other and spaced apart along the height direction of the vehicle 1. Both first groove sidewalls 112 can have drain ports 113. The liquid in the mounting groove 111 can fall onto the lower first groove sidewall 112 under the action of gravity. The liquid in the mounting groove 111 can be discharged from the dustproof body 11 through the drain port 113 on the lower first groove sidewall 112. When the dustproof device 10 is installed on the left door 200 and the right door 200 of the vehicle 1 respectively, the two dustproof devices 10 are placed in opposite directions along the height direction of the vehicle 1. By setting drain ports 113 on the side walls 112 of the two first grooves, it is beneficial to improve the versatility and practicality of the dustproof device 10.

[0030] As an example, the two first groove sidewalls 112 can be referred to as first sidewall 1121 and second sidewall 1122, respectively. When the dustproof device 10 is installed on the left front door 200 of the vehicle 1, the first sidewall 1121 can be located above the second sidewall 1122, and the liquid in the mounting groove 111 can be discharged from the dustproof body 11 through the drain port 113 on the second sidewall 1122. When the dustproof device 10 is installed on the right front door 200 of the vehicle 1, the second sidewall 1122 can be located above the first sidewall 1121, and the liquid in the mounting groove 111 can be discharged from the dustproof body 11 through the drain port 113 on the first sidewall 1121.

[0031] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the first tank sidewall 112 has a plurality of drain ports 113, which are arranged along the depth direction of the mounting tank 111.

[0032] Multiple drain ports 113 can be formed on the side wall 112 of the first groove. Liquid in the mounting groove 111 can be discharged from the dustproof body 11 through the multiple drain ports 113, which helps to improve the efficiency of liquid discharge from the mounting groove 111 to the dustproof body 11. The multiple drain ports 113 on the side wall 112 of the first groove can be arranged along the depth direction of the mounting groove 111, and the multiple drain ports 113 can be spaced apart along the depth direction of the mounting groove 111. Liquid in the mounting groove 111 can be discharged from different positions on the corresponding side wall 112 of the first groove along the depth direction of the mounting groove 111, which helps to reduce the probability of liquid accumulating in the mounting groove 111, further reduces the probability of corrosion of the door limiter 20, and further extends the service life of the door limiter 20.

[0033] In some embodiments of this utility model, such as Figure 7 As shown, a flow guiding structure is formed on the inner surface of the first tank sidewall 112, which is used to guide the liquid in the installation tank 111 to the corresponding drain port 113.

[0034] The liquid in the mounting groove 111 can flow on the inner surface of the first groove sidewall 112. A flow-guiding structure can be formed on the inner surface of the first groove sidewall 112 to guide the liquid in the mounting groove 111. A drain port 113 can be formed on the first groove sidewall 112. The flow-guiding structure can direct the liquid in the mounting groove 111 to the corresponding drain port 113. The liquid in the mounting groove 111 can flow to the corresponding drain port 113 under the action of the flow-guiding structure, which helps to further reduce the probability of liquid accumulation in the mounting groove 111, further reduces the probability of corrosion of the door limiter 20, and further extends the service life of the door limiter 20.

[0035] In some embodiments of this utility model, such as Figure 7 As shown, the flow guiding structure is a flow guiding channel 114, which is connected to the corresponding drain port 113.

[0036] The flow guiding structure can be a flow guiding groove 114. The flow guiding groove 114 can be recessed into the inner surface of the corresponding first groove sidewall 112. The liquid in the installation groove 111 can flow in the flow guiding groove 114. The flow guiding groove 114 can be connected to the corresponding drain port 113. The liquid in the installation groove 111 can flow into the flow guiding groove 114 and then be discharged from the dustproof body 11 through the corresponding drain port 113. This is beneficial to further realize the effect of the flow guiding structure guiding the liquid in the installation groove 111 to the corresponding drain port 113.

[0037] As an example, the guide channel 114 can be arranged adjacent to the corresponding drain port 113, and the guide channel 114 can be connected to the corresponding drain port 113. There can be multiple guide channels 114, and multiple guide channels 114 can be arranged one-to-one with multiple drain ports 113. Each guide channel 114 has a corresponding drain port 113 connected to it, which is conducive to further realizing the effect of the guide channel 114 guiding the liquid in the installation tank 111 to the corresponding drain port 113, and improving the efficiency of liquid discharge from the installation tank 111 to the dustproof body 11.

[0038] In some embodiments of this utility model, such as Figure 7 As shown, the guide channel 114 and the corresponding drain port 113 are arranged along the depth direction of the installation channel 111. The bottom wall of the guide channel 114 extends inclinedly along the depth direction of the installation channel 111, and from the direction of the guide channel 114 to the corresponding drain port 113, the bottom wall of the guide channel 114 is inclined in the direction away from the installation channel 111.

[0039] The guide channel 114 and the corresponding drain port 113 can be arranged along the depth direction of the mounting groove 111, and the guide channel 114 can extend along the depth direction of the mounting groove 111. The bottom wall of the guide channel 114 can extend obliquely along the depth direction of the mounting groove 111. Along the depth direction of the mounting groove 111, one end of the bottom wall of the guide channel 114 can be connected to the inner surface of the first groove side wall 112, and the other end of the bottom wall of the guide channel 114 can be connected to the corresponding drain port 113. From the direction of the guide channel 114 to the corresponding drain port 113, the bottom wall of the guide channel 114 can be inclined in a direction away from the mounting groove 111. Along the arrangement direction of the two first groove side walls 112, the distance between one end of the bottom wall of the guide channel 114 and the mounting groove 111 is less than the distance between the other end of the bottom wall of the guide channel 114 and the mounting groove 111. When the liquid in the mounting groove 111 flows into the guide groove 114, the liquid in the mounting groove 111 can flow from the guide groove 114 to the corresponding drain port 113 under the action of gravity. This helps to achieve the effect of the liquid in the mounting groove 111 automatically flowing out of the mounting groove 111, which helps to further improve the efficiency of the liquid in the mounting groove to drain from the dustproof body 11, helps to further reduce the probability of liquid accumulating in the mounting groove 111, helps to further reduce the probability of door limiter 20 corrosion, and helps to further extend the service life of door limiter 20.

[0040] In some embodiments of this utility model, such as Figure 4 As shown, the dustproof body 11 has a first limiting part 115, which is used to cooperate with the door limiter 20 to limit the relative position of the door limiter 20 and the dustproof body 11 along the depth direction of the mounting groove 111.

[0041] The dustproof body 11 may have a first limiting part 115, which can be used to limit the engagement with the door limiter 20. The dustproof body 11 can be connected to the door limiter 20 through the first limiting part 115. As an example, the dustproof body 11 can be snapped together with the door limiter 20 through the first limiting part 115, which facilitates the disassembly and installation of the dustproof body 11 and improves the installation efficiency of the dustproof device 10. When the first limiting part 115 and the door limiter 20 are engaged, it helps to limit the relative position of the door limiter 20 and the dustproof body 11 along the depth direction of the mounting groove 111, keeps the relative position of the door limiter 20 and the dustproof body 11 along the depth direction of the mounting groove 111 unchanged, reduces the probability of the dustproof body 11 falling off the door limiter 20, and improves the reliability of the dustproof device 10.

[0042] As an example, the limiter housing 22 is fixed to the door 200. The limiter housing 22 may have a second limiting part 221, and the first limiting part 115 and the second limiting part 221 can be engaged for limiting. When the door 200 is opened, the relative position of the limiter housing 22 and the door 200 remains unchanged, and the relative position of the dustproof body 11 and the limiter housing 22 also remains unchanged.

[0043] As an example, the first limiting part 115 can be one of a limiting block or a limiting groove, and the second limiting part 221 can be the other of a limiting block or a limiting groove. The limiting block can be assembled into the limiting groove, thereby achieving the effect of limiting cooperation between the first limiting part 115 and the door limiter 20. In this embodiment, the first limiting part 115 is used as a limiting groove and the first limiting part 115 is used as a limiting block as an example for explanation.

[0044] In some embodiments of this utility model, such as Figure 1 , Figure 5 and Figure 7 As shown, the dustproof device 10 may further include: a flange structure 12, which is arranged around the open end of the mounting groove 111 in the circumferential direction. The flange structure 12 is fixedly connected to the dustproof body 11 and bends outward from the dustproof body 11. The flange structure 12 is used to assemble with the door 200 of the vehicle 1.

[0045] The flange structure 12 can be arranged circumferentially around the open end of the mounting groove 111. The flange structure 12 can be connected to the dustproof body 11, or it can be bonded to the dustproof body 11. The flange structure 12 can be integrally formed with the dustproof body 11. The flange structure 12 can be bent outward toward the dustproof body 11, and it can be bent to connect with the dustproof body 11. An angle can be formed between the flange structure 12 and the dustproof body 11, and the angle can be an obtuse angle. When the dustproof device 10 is installed on the vehicle 1, the flange structure 12 can be used to assemble with the door 200 of the vehicle 1. The flange structure 12 can abut and limit the door 200 of the vehicle 1, which helps to increase the contact area between the flange structure 12 and the door 200 of the vehicle 1, improves the sealing effect between the dustproof device 10 and the door 200 of the vehicle 1, reduces the probability of dust, sand and other pollutants entering the mounting groove 111 through the gap between the dustproof device 10 and the door 200, further reduces the mechanical wear of the door limiter 20, and further extends the service life of the door limiter 20.

[0046] It should be noted that, taking the mounting groove 111 of the dustproof body 11 as the boundary, the side inside the mounting groove 111 is the inner side of the dustproof body 11, and the side outside the mounting groove 111 is the outer side of the dustproof body 11.

[0047] As an example, the door 200 may include an inner door panel 210 and an inner panel reinforcing plate 220. The inner panel reinforcing plate 220 is located inside the inner door panel 210 and is welded to the inner door panel 210. When the door limiter 20 is installed on the vehicle 1 and the dustproof device 10 and the door limiter 20 are used together, the flange structure 12 can abut against and limit the inner panel reinforcing plate 220. This helps to improve the sealing effect between the dustproof device 10 and the inner panel reinforcing plate 220, reduces the probability of dust, sand and other pollutants entering the mounting groove 111 through the gap between the dustproof device 10 and the inner panel reinforcing plate 220, further reduces the mechanical wear of the door limiter 20, and further extends the service life of the door limiter 20.

[0048] As an example, the dustproof device 10 can be made of a flexible sealing material, such as silicone or thermoplastic elastomer, which helps improve its elasticity and anti-aging properties. By assembling the flanged structure 12 with the door 200, the flanged structure 12 can abut against and limit the door 200, and it can fit tightly against the inner panel reinforcement plate 220 without gaps. When the flanged structure 12 abuts against the door 200, it can undergo slight deformation, which further improves the sealing effect between the dustproof device 10 and the door 200 of the vehicle 1, reduces the probability of dust, sand, and other contaminants entering the mounting groove 111 through the gap between the dustproof device 10 and the inner panel reinforcement plate 220, reduces mechanical wear on the door limiter 20, and extends its service life.

[0049] According to a second aspect of the present invention, a door limiter system 100 includes a door limiter 20 and a dustproof device 10 for the door limiter 20 in the above embodiment, wherein at least a portion of the door limiter 20 is installed in a mounting groove 111.

[0050] The door limiter system 100 according to the embodiments of this application includes a door limiter 20 and a dustproof device 10 for the door limiter 20 in the above embodiments. At least a portion of the door limiter 20 can be installed in the mounting groove 111. The door limiter 20 can pass through the open end of the mounting groove 111. The dustproof device 10 can cover at least a portion of the door limiter 20. The dustproof device 10 can protect the door limiter 20. The dustproof device 10 can prevent dust and water from entering the door limiter 20, which helps to reduce the probability of wear and corrosion of the door limiter 20, extend the service life of the door limiter 20, improve the reliability of the door limiter system 100, and extend the service life of the door limiter system 100.

[0051] The vehicle 1 according to the third aspect of the present invention includes the door limiter system 100 in the above embodiment.

[0052] According to the embodiments of this application, the use of the door limiter system 100 in the above embodiments of the vehicle 1 is beneficial to improving the reliability of the door 200 when opening and closing, reducing the frequency of maintenance of the door limiter system 100, and reducing costs.
