Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a sealing strip and a vehicle. Background Technology

[0002] The tailgate is an integral part of a vehicle's structure. In some vehicles, the tailgate window is separate from the tailgate itself, and the tailgate is opened by side opening or by lifting the glass. In related technologies, weatherstripping is installed on the windows for waterproofing. However, in these technologies, after the weatherstripping is installed on the window, a relatively sealed cavity is formed between the weatherstripping and the window. Water can seep into this cavity along the contact surface between the weatherstripping and the window and cannot drain out, resulting in water accumulation in the vehicle's windows and poor drainage.

[0003] It is evident that the relevant technology suffers from poor drainage in the cavity between the window and the sealing strip. Summary of the Invention

[0004] This invention provides a sealing strip and a vehicle to solve the problem of poor drainage in the cavity between the window and the sealing strip in related technologies.

[0005] To achieve the above objectives, embodiments of the present invention provide a sealing strip, comprising:

[0006] The main body is a long, hollow structure. A partition extending along the axis of the main body is provided inside the hollow structure, which divides the hollow structure into a first cavity and a second cavity. The main body is provided with at least one first through hole, through which the first cavity communicates with the outside.

[0007] A first fastener is connected to one end of the main body. The first fastener has a drainage hole that communicates with the first cavity. The first fastener is used to fix the outer frame of the vehicle window.

[0008] A support portion is located on the side of the main body near the at least one first through hole, and the support portion is arranged along the axis of the main body;

[0009] When the first fastener is fixed to the outer frame, the main body and the supporting part abut against the outer frame respectively to form a closed structure. The closed structure is connected to the first cavity through the at least one first through hole.

[0010] In one embodiment, the distance between each of the at least one first through hole and the support portion is greater than or equal to a first predetermined distance threshold.

[0011] In one embodiment, each of the at least one first through hole is located on a first straight line, the first straight line being parallel to the axis of the body;

[0012] The distance between each of the first through holes is matched.

[0013] In one embodiment, the distance between each of the at least one first through hole and the abutment position between the body and the outer frame is greater than or equal to a second predetermined distance threshold.

[0014] In one embodiment, the main body is provided with at least one second through hole, and the second cavity communicates with the outside through the at least one second through hole.

[0015] In one embodiment, each of the at least one second through hole is located on a second straight line, the second straight line being parallel to the axis of the body;

[0016] The distance between each of the second through holes is matched.

[0017] In one embodiment, a second fastener is further included, which is a U-shaped structure used to fix the outer frame.

[0018] In one embodiment, the U-shaped structure has at least one elastic protrusion, which is used to abut against the outer frame when the U-shaped structure is fixed to the outer frame.

[0019] In one embodiment, a third fastener is further included, which is connected to the end of the main body away from the first fastener. The third fastener is provided with the drainage hole, which communicates with the first cavity. The third fastener is used to fix the outer frame.

[0020] This invention also provides a vehicle that includes a sealing strip as described in any of the preceding embodiments.

[0021] One of the above technical solutions has the following advantages or beneficial effects:

[0022] In this embodiment of the invention, the sealing strip includes: a main body, which is a long, hollow structure with a partition extending along the axis of the main body inside, dividing the hollow structure into a first cavity and a second cavity; the main body has at least one first through hole, through which the first cavity communicates with the outside; a first fixing member, which is connected to one end of the main body and has a drainage hole communicating with the first cavity, and is used to fix the first fixing member to the outer frame of the window; and a support portion, which is located on the side of the main body near the at least one first through hole and is arranged along the axis of the main body; wherein, when the first fixing member is fixed to the outer frame, the main body and the support portion abut against the outer frame respectively, forming a closed structure, and the closed structure communicates with the first cavity through the at least one first through hole. Thus, water accumulated in the closed structure is guided into the first cavity through the at least one first through hole, and water inside the first cavity is drained through the drainage hole, thereby improving the drainage effect of the cavity between the window and the sealing strip.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the present invention provides a sealing strip, comprising:

[0031] The main body 10 is a long, hollow structure. A partition extending along the axis of the main body 10 is provided inside the hollow structure, which divides the hollow structure into a first cavity 101 and a second cavity 102. The main body 10 is provided with at least one first through hole 1011, through which the first cavity 101 communicates with the outside.

[0032] The first fastener 20 is connected to one end of the main body 10. The first fastener 20 is provided with a drainage hole 201, which communicates with the first cavity 101. The first fastener 20 is used to fix the outer frame of the vehicle window.

[0033] A support portion 30 is located on the side of the main body 10 near the at least one first through hole 1011, and the support portion 30 is arranged along the axis of the main body 10;

[0034] When the first fixing member 20 is fixed to the outer frame, the main body 10 and the support part 30 respectively abut against the outer frame to form a closed structure. The closed structure is connected to the first cavity 101 through the at least one first through hole 1011.

[0035] The aforementioned main body 10 is used to seal the outer edge of the vehicle window frame. The shape of the main body 10 can be adapted to the shape of the vehicle window frame, so that after the main body 10 is installed with the vehicle window, it can completely cover the gap between the vehicle window and the vehicle frame.

[0036] At least one first through hole 1011 in the main body 10 is used to guide water accumulated in the closed structure into the first cavity 101, so that the water in the closed structure can be smoothly discharged, thereby improving the efficiency of water drainage. The number of first through holes 1011 needs to be set according to the length of the main body 10; the longer the main body 10 is, the more first through holes 1011 are required.

[0037] It should be noted that the car windows are in a vertical position when closed, such as... Figure 4 As shown, the water will flow downwards under the influence of gravity. Therefore, in actual use, it is only necessary to install the main body 10 of this embodiment of the invention below the horizontal level of the car window to drain the water below the car window, thereby improving the efficiency of draining the water.

[0038] The aforementioned first fastener 20 is used to fix the body 10 to the outer frame of the window. The first fastener 20 is located at one end of the main body 10, thus enabling the main body 10 to be installed to the outer frame of the window. The first fastener 20 is provided with a drainage hole 201, which allows water to be drained from the first cavity 101 of the main body 10.

[0039] In some embodiments, the main body 10 is inclined and the connection between the main body 10 and the first fixing member 20 is located at the lowest horizontal point. In this way, the water in the first cavity 101 flows towards the first fixing member 20 under the action of gravity and is discharged through the drain hole 201, thereby further improving the drainage efficiency.

[0040] In some implementations, such as Figure 3 As shown, the first fixing member 20 is provided with a guide slope. The guide slope has a certain angle with the horizontal direction. The water flow of the first fixing member 20 can be guided away by the guide slope to avoid water accumulation in the first fixing member 20.

[0041] The aforementioned support portion 30 supports the main body 10, enabling the main body 10 and the outer frame of the window to form a stable closed structure. This stable closed structure allows accumulated water to continuously enter the first cavity 101 through at least one first through hole 1011, thereby facilitating the smooth drainage of the accumulated water. For example, as shown... Figure 1 As shown, the main body 10, the support part 30 and the outer frame form a triangular closed structure. Under the action of gravity, water flows down the triangular closed structure and into the first cavity 101, thereby draining the accumulated water.

[0042] In this embodiment of the invention, both the main body 10 and the support portion 30 are elastic structures.

[0043] In this embodiment of the invention, the sealing strip includes: a main body 10, which is a long, hollow structure. A partition extending along the axis of the main body 10 is provided within the hollow structure, dividing the hollow structure into a first cavity 101 and a second cavity 102. The main body 10 has at least one first through hole 1011, through which the first cavity 101 communicates with the outside. A first fixing member 20 is connected to one end of the main body 10, and has a drainage hole 201 communicating with the first cavity 101. The first fixing member 20 is used to fix the outer frame of the vehicle window. A support portion 30 is located on the side of the main body 10 near the at least one first through hole 1011, and is arranged along the axis of the main body 10. When the first fixing member 20 is fixed to the outer frame, the main body 10 and the support portion 30 abut against the outer frame, forming a closed structure. The closed structure communicates with the first cavity 101 through the at least one first through hole 1011. In this way, water accumulated in the closed structure is introduced into the first cavity 101 through at least one first through hole 1011, and then water accumulated inside the first cavity 101 is discharged through the drain hole 201, thereby improving the drainage effect of the cavity between the window and the sealing strip.

[0044] In one embodiment, the distance between each of the at least one first through hole 1011 and the support portion 30 is greater than or equal to a first set distance threshold.

[0045] It should be noted that the sealing strip is used to isolate the vehicle's internal and external environments. After prolonged use, dust will accumulate on the outside of the sealing strip, and in the presence of water, the dust will accumulate inside the sealed structure. In this embodiment of the invention, by setting the distance between each of the at least one first through hole 1011 and the support portion 30 to be greater than or equal to a first preset distance threshold, when water carries dust, the dust at the bottom of the water cannot enter the first cavity 101 through the first through hole 1011, thereby avoiding blockage of the first through hole 1011 and the first cavity 101.

[0046] The first set distance threshold can be set based on experience, and can usually be set to 1 to 3 millimeters.

[0047] Furthermore, a filter structure can be provided in each of the first through holes 1011 to filter out larger dust or particles, thereby preventing the first cavity 101 from being blocked by larger dust or particles.

[0048] In one embodiment, each of the at least one first through hole 1011 is located on a first straight line, which is parallel to the axis of the body 10;

[0049] The distances between each of the first through holes 1011 are matched.

[0050] In an embodiment of the invention, each of the at least one first through hole 1011 is located on a first straight line, the first straight line is parallel to the axis of the main body 10, and the distance between each first through hole 1011 is adapted so that each first through hole 1011 guides the water accumulated at different positions of the main body 10 to flow into the first cavity 101.

[0051] In this case, when each first through hole 1011 is located on the first straight line, the distance between each first through hole 1011 and the support part 30 is greater than or equal to the first set distance threshold, thereby avoiding blockage of each first through hole 1011 and the first cavity 101.

[0052] In one embodiment, the distance between each of the at least one first through hole 1011 and the abutment position between the body 10 and the outer frame is greater than or equal to a second preset distance threshold.

[0053] In this embodiment of the invention, the distance between each first through hole 1011 and the contact position between the main body 10 and the outer frame is greater than or equal to a second set distance threshold, so that each first through hole 1011 is kept facing the inside of the closed structure, avoiding the part of the first through hole 1011 directly facing the external environment, causing dust or larger particles in the external environment to enter the first cavity 101 through the first through hole 1011.

[0054] The first set distance threshold can be set based on experience, and can usually be set to 1 to 3 millimeters.

[0055] Furthermore, a filter structure can be provided in each of the first through holes 1011 to filter out larger dust or particles, thereby preventing the first cavity 101 from being blocked by larger dust or particles.

[0056] In one embodiment, the main body 10 is provided with at least one second through hole 1021, and the second cavity 102 communicates with the outside through the at least one second through hole 1021.

[0057] In this embodiment of the invention, the main body 10 is provided with at least one second through hole 1021, and the second cavity 102 is connected to the outside through at least one second through hole 1021. In this way, the gas inside the second cavity 102 can be discharged through the second through hole 1021, thereby achieving the sealing of the door by the shape of the sealing strip matching the gap between the door and the outer frame when the door is closed and the sealing strip is in a compressed state.

[0058] In one embodiment, each of the at least one second through hole 1021 is located on a second straight line, the second straight line being parallel to the axis of the body 10;

[0059] The distance between each of the second through holes 1021 is adapted.

[0060] In this embodiment of the invention, each of the at least one second through hole 1021 is located on a second straight line, and the second straight line is parallel to the axis of the main body 10; the distance between each second through hole 1021 is adapted so that each second through hole 1021 can discharge gas from different positions of the main body 10, ensuring that the degree of deformation at different positions of the main body 10 is the same.

[0061] In one embodiment, a second fastener 40 is further included, which is a U-shaped structure used to fix the outer frame.

[0062] It should be noted that the outer frame of a car window is used to secure the window, and different frames have different shapes. For example... Figure 1 The outer frame shown is an L-shaped structure. In order to strengthen the connection between the sealing strip and the outer frame, in this embodiment of the invention, the sealing strip also includes a second fixing member 40. The second fixing member 40 is a U-shaped structure, which is used to fix it to the outer frame, thereby improving the connection strength between the sealing strip and the outer frame.

[0063] Furthermore, the second fastener 40 can be a long strip structure arranged along the axis of the main body 10, or it can include multiple sub-fasteners arranged along the axis of the main body 10, with the multiple sub-fasteners spaced apart, thereby improving the connection strength between the sealing strip and the outer frame.

[0064] In this embodiment of the invention, the second fastener 40 is an elastic structure.

[0065] In one embodiment, the U-shaped structure is provided with at least one elastic protrusion 401, which is used to abut against the outer frame when the U-shaped structure is fixed to the outer frame.

[0066] In this embodiment of the invention, at least one elastic protrusion 401 is provided in the U-shaped structure. The elastic protrusion 401 is used to abut against the outer frame when the U-shaped structure is fixed to the outer frame. The connection strength between the sealing strip and the outer frame is further improved by the elastic protrusion 401.

[0067] In one embodiment, a third fixing member 21 is further included. The third fixing member 21 is connected to the end of the main body 10 away from the first fixing member 20. The third fixing member 21 is provided with the drainage hole 201, which communicates with the first cavity 101. The third fixing member 21 is used to fix the outer frame.

[0068] In this embodiment of the invention, the sealing strip further includes a third fixing member 21, which is connected to the end of the main body 10 away from the first fixing member 20. The third fixing member 21 is provided with a drainage hole 201, which communicates with the first cavity 101. The third fixing member 21 is used to fix the outer frame. In this way, the first fixing member 20 and the third fixing member 21 fix both ends of the sealing strip to the outer frame, which can effectively improve the connection strength between the sealing strip and the outer frame.

[0069] This invention also provides a vehicle door, including the aforementioned sealing strip.
