DETAILED DESCRIPTION

[0040] The following are preferred implementations of the present application. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications are also considered to be within the scope of protection of the present application.

[0041] The following is a detailed introduction to the relevant technology. In a vehicle, a water-cut sealing strip is usually provided on the outer surface and inner surface of the vehicle peripheral parts, so that the sealing part of the water-cut sealing strip overlaps the vehicle peripheral parts. The water-cut sealing strip is also called a door water-cut, which is usually a sealing strip in the window groove, located between the window glass and the door frame. Its main functions include cleaning and aesthetics. Cleaning function: When raising or lowering the window glass, the water-cut sealing strip can gently wipe off the water droplets, water mist and dust on the window glass, so that the window remains clear and the clarity of the driving field of vision is improved. Aesthetics: It adds a touch of beauty to the entire vehicle and improves the overall appearance quality of the vehicle.

[0042] In a humid environment, there may be more condensation on the surface of the vehicle, causing the water vapor on the window glass surface to slide to the bottom due to gravity. When the vehicle is parked in a cold environment, the water will cool rapidly, especially at night or in the early morning, which will cause the water to condense and freeze. Specifically, the condensed water droplets will gather in the reservoir, and the gathered water droplets cannot be quickly discharged and will quickly condense into ice in winter, thereby freezing the doors and windows of the vehicle and making it impossible to raise or lower them normally. In addition, the more water accumulates in the reservoir, the thicker the frozen ice will be, and the space in the reservoir is relatively narrow, making it difficult to de-ice normally with tools. The solutions of the related art mainly use defrost sprays or heaters, which have limited effects and are not convenient enough. Therefore, how to achieve the rapid defrosting and de-icing function of the reservoir of the sealing strip is an urgent problem to be solved.

[0043] Please refer to Figure 1-Figure 8 This embodiment provides a sealing strip 1, which is applied to a vehicle peripheral part 2. The sealing strip 1 includes a main body 11, a sealing portion 12 connected to the main body 11, and a heating portion 13 embedded in the sealing portion 12. The sealing portion 12 is arranged at an angle to the main body 11, and the end of the sealing portion 12 away from the main body 11 is used to abut the vehicle peripheral part 2.

[0044] A liquid storage tank 14 is formed between the main body 11 , the sealing portion 12 and the vehicle peripheral component 2 , and the heating portion 13 is used for heating the liquid in the liquid storage tank 14 .

[0045] The vehicle peripheral part 2 may be a vehicle window glass or a vehicle body panel. The vehicle window glass may be a front windshield, a rear windshield, a side window glass, a corner window glass, etc. The vehicle peripheral part 2 includes an outer surface 21 and an inner surface that are arranged opposite to each other, the outer surface 21 is arranged to face the outside, and the inner surface is arranged to face the inside of the vehicle. Optionally, the heating part 13 is arranged on the sealing part 12 that abuts against the outer surface 21; and / or, the heating part 13 is arranged on the sealing part 12 that abuts against the inner surface. Figure 1 and Figure 4 , Figure 7 and Figure 8 As shown, the vehicle peripheral component 2 is a vehicle window glass.

[0046] The sealing strip 1 includes a main body 11, a sealing portion 12 and a heating portion 13. The sealing portion 12 is elastic. The main body 11 and the sealing portion 12 are an integrated structure, and the main body 11 is bent to connect the sealing portion 12. One end of the sealing portion 12 is connected to the main body 11, and the other end abuts against the vehicle peripheral part 2. The vehicle peripheral part 2 can move relative to the sealing strip 1. The main body 11 and the sealing portion 12 are arranged at an angle, for example, the angle between the main body 11 and the sealing portion 12 is an acute angle. The materials of the main body 11 and the sealing portion 12 can be plastics such as PVC, TPE, or EPDM, and rubber and other adhesives. The sealing portion 12 can abut against the edge of the vehicle window glass. For example, as Figure 7 and Figure 8 As shown, the sealing portion 12 abuts against the top edge of the window glass. Figure 1 and Figure 4 As shown, the sealing portion 12 abuts against the bottom edge of the vehicle window glass. For another example, the sealing portion 12 abuts against the side edge of the vehicle window glass. The sealing portion 12 can abut against the edge of the vehicle body panel. For example, the sealing portion 12 abuts against the top edge of the vehicle body panel. For another example, the sealing portion 12 abuts against the bottom edge of the vehicle body panel. For another example, the sealing portion 12 abuts against the side edge of the vehicle body panel. By making the sealing portion 12 abut against the edges of the vehicle peripheral component 2, the sealing performance between the vehicle peripheral component 2 and the vehicle body can be improved, dust can be reduced from entering the vehicle interior, and the noise generated by friction can be reduced, thereby improving the user experience.

[0047] The heating part 13 is embedded in the sealing part 12, and it can also be understood that the sealing part 12 wraps the heating part 13. The heating part 13 can be connected to a power supply through a wire. When the heating part 13 is in a powered state, the heating part 13 generates heat to heat the liquid storage tank 14. There is a gap between the heating part 13 and the vehicle peripheral part 2. Optionally, the extension direction of the heating part 13 is the same as the extension direction of the sealing part 12. The material of the heating part 13 can be a conductive and thermally conductive material such as a metal or an alloy. Specifically, the material of the heating part 13 can be a metal or alloy such as silver, copper, gold, aluminum, iron, nickel, or tungsten. The cross-sectional shape of the heating part 13 can be circular, rectangular, square, etc., which is not limited in this embodiment. The shape of the heating part 13 can be a sheet, a strip, a filament, a block, etc., which is not limited in this embodiment.

[0048] In one embodiment, the heating part 13, the sealing part 12 and the main body 11 are integrally formed structural parts. Specifically, the heating part 13 is used as an insert, and the rubber sealing part 12 and the main body 11 are co-extruded on the insert. Such preparation can not only improve the connection performance between the main body 11, the sealing part 12 and the heating part 13, thereby improving the structural stability of the sealing strip 1, but also the heating part 13 can play a role in supporting and shaping the sealing part 12 and the main body 11, further improving the structural stability of the sealing strip 1.

[0049] Specifically, when the vehicle peripheral component 2 moves relative to the sealing strip 1, at least part of the liquid accumulates in the liquid reservoir 14. The heating unit 13 can heat the liquid reservoir 14 to evaporate the liquid in the liquid reservoir 14, thereby achieving the defrosting and deicing function of the sealing strip 1, avoiding the phenomenon that the vehicle peripheral component 2 cannot be used normally due to the condensation of the liquid in the liquid reservoir 14 into ice, thereby improving the reliability of the vehicle.

[0050] Furthermore, the heating part 13 is embedded in the sealing part 12, which reduces the requirement for the heating part 13 to be waterproof, reduces the risk of the heating part 13 failing due to water vapor, and plays a role in waterproofing, moisture-proofing, and preventing the risk of short circuits.

[0051] Please refer to Figure 1-Figure 6 In one embodiment, the heating portion 13 is disposed adjacent to the bottom wall of the liquid storage tank 14 ; or, the heating portion 13 is disposed corresponding to the bottom wall of the liquid storage tank 14 .

[0052] For example, the heating portion 13 is disposed in the middle and lower part of the sealing portion 12, adjacent to the bottom wall of the liquid storage tank 14. For another example, at least part of the heating portion 13 is disposed in the portion of the sealing portion 12 corresponding to the bottom wall of the liquid storage tank 14. In summary, this embodiment is conducive to heating and evaporating the liquid from the bottom of the liquid storage tank 14 by limiting the position of the heating portion 13 in the liquid storage tank 14, which can effectively reduce the phenomenon of condensation into ice and avoid liquid remaining in the liquid storage tank 14, thereby improving the defrosting and deicing effect of the heating portion 13.

[0053] Please refer to Figure 1-Figure 6 In one embodiment, the bottom wall of the liquid storage tank 14 is set at an angle to the main body 11, and the bottom wall of the liquid storage tank 14 includes an arc segment 141 and an inclined segment 142, the arc segment 141 is connected between the main body 11 and the inclined segment 142, and the arc segment 141 is farther away from the opening of the liquid storage tank 14 than the inclined segment 142; the heating part 13 is arranged adjacent to the arc segment 141; or, the heating part 13 is arranged corresponding to the arc segment 141.

[0054] The arc segment 141 is closer to the bottom of the liquid storage tank 14 than the inclined segment 142, and it can also be understood that the depth of the arc segment 141 is greater than the depth of the inclined segment 142. The arc segment 141 is protruding in the direction away from the opening of the liquid storage tank 14. The angle between the arc segment 141 and the main body 11 is an acute angle, and the angle between the inclined segment 142 and the main body 11 is an acute angle. For example, the heating part 13 is arranged corresponding to the arc segment 141. For another example, the heating part 13 is arranged corresponding to the arc segment 141 and the inclined segment 142. For another example, the heating part 13 is arranged corresponding to the connection between the arc segment 141 and the inclined segment 142. For another example, the heating part 13 is arranged corresponding to the part of the inclined segment 142 close to the arc segment 141.

[0055] Optionally, the width of the arc segment 141 gradually decreases along the direction from the bottom wall of the liquid storage tank 14 to the opening. Optionally, the width between the arc segment 141 and the main body 11 is smaller than the width between the inclined segment 142 and the main body 11.

[0056] In summary, in this embodiment, the bottom wall of the liquid storage tank 14 is divided into an arc segment 141 and an inclined segment 142, and the arc segment 141 is closer to the bottom of the storage tank than the inclined segment 142. On the one hand, by further optimizing the shape of the liquid storage tank 14, the arc segment 141 can increase the contact area between the liquid in the liquid storage tank 14 and the bottom wall of the liquid storage tank 14, which is conducive to rapid heating and evaporation of the liquid. The inclined segment 142 makes the liquid in the liquid storage tank 14 have a tendency to slide toward the arc segment 141 under the action of gravity, reducing the probability of liquid remaining in the liquid storage tank 14, which is further conducive to rapid heating and evaporation of the liquid. On the other hand, the position of the heating part 13 will be further limited, so that the heating part 13 is arranged adjacent to or corresponding to the arc segment 141, and the heat is more concentrated on the arc segment 141 where the contact area between the liquid in the liquid storage tank 14 and the bottom wall of the liquid storage tank 14 is larger, thereby further improving the defrosting and deicing effect of the heating part 13.

[0057] Further optionally, the width of the heating portion 13 provided in the arc segment 141 is greater than the width of the heating portion 13 provided in the inclined segment 142. In this embodiment, by limiting the width of the heating portion 13 in the arc segment 141 and the inclined segment 142, the heat provided by the heating portion 13 to the arc segment 141 is greater than the heat provided by the heating portion 13 to the inclined segment 142, so that in the process of evaporating the liquid in the liquid storage tank 14, the arc segment 141 can be heated to evaporate the liquid, and the inclined segment 142 can be used as an auxiliary to slowly heat and melt the frost, so that the frost turns into liquid and slides toward the arc segment 141 under the action of gravity. In addition, such a setting can also save energy, control the heat in the liquid storage tank 14, and concentrate more heat on the arc segment 141 away from the opening of the liquid storage tank 14, thereby avoiding the possibility of scalding accidents.

[0058] Please refer to Figure 1-Figure 3In one embodiment, the heating portion 13 includes a heating plate, and the heating plate is arranged corresponding to the arc segment 141 and the inclined segment 142 , and the shape of the heating plate is adapted to the shapes of the arc segment 141 and the inclined segment 142 .

[0059] On the one hand, the heating portion 13 is provided with a heating sheet, which not only increases the heating area and heat conduction effect of the heating portion 13, but also provides greater support force for the main body 11 and the sealing portion 12, thereby improving the stability of the sealing strip 1. On the other hand, the heating sheet is provided corresponding to the arc segment 141 and the inclined segment 142, which can further increase the contact area between the heating sheet and the liquid storage tank 14, further increase the heating area and heat conduction effect of the heating portion 13, and thus improve the defrosting and deicing effect of the heating portion 13.

[0060] In one embodiment, the heating portion 13 includes a heating plate, and a width W of the heating plate satisfies the following condition: W ≥ 0.1 mm; and / or a length L of the heating plate satisfies the following condition: L ≥ 0.5 mm.

[0061] Specifically, the width W of the heating plate can be 0.1 mm, or 0.2 mm, 0.3 mm, or 0.4 mm, or 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, etc. The length L of the heating plate can be 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, or 1.5 mm, or 2 mm, etc.

[0062] This embodiment limits the width W ≥ 0.1 mm and / or the length L ≥ 0.5 mm of the heating plate, which can not only prevent the heating plate from being too thin, reduce the probability of the heating plate being easily deformed and broken, and improve the reliability of the heating plate, but also prevent the heating plate from failing to shape the sealing portion 12, thereby reducing the difficulty of preparation.

[0063] Please refer to Figure 4-Figure 6 In one embodiment, the heating portion 13 includes a heating wire, and the heating wire is correspondingly arranged at the connection between the main body 11 and the arc segment 141; and / or, the heating wire is correspondingly arranged at the connection between the arc segment 141 and the inclined segment 142.

[0064] The number of heating wires is at least one. For example, the heating wire is only correspondingly provided at the connection between the main body 11 and the arc segment 141. For another example, the heating wire is only correspondingly provided at the connection between the arc segment 141 and the inclined segment 142. For another example, the number of heating wires is two, correspondingly provided at both the connection between the main body 11 and the arc segment 141 and the connection between the arc segment 141 and the inclined segment 142.

[0065] On the one hand, by providing the heating wire, the difficulty of preparation can be reduced, and the main body 11 and the sealing part 12 can firmly fix the heating wire, thereby improving the stability of the sealing strip 1. On the other hand, the heating wire is provided at the connection between the main body 11 and the arc segment 141, and at the connection between the arc segment 141 and the inclined segment 142, which can help to supply more heat of the heating part 13 to the arc segment 141, and then partially to the inclined segment 142, so that the arc segment 141 can be heated to evaporate the liquid, and the inclined segment 142 can be used as an auxiliary to slowly heat and melt the frost, so that the frost turns into liquid and slides toward the arc segment 141 under the action of gravity.

[0066] Moreover, such a configuration can also save energy, control the heat in the liquid storage tank 14, and concentrate more heat on the arc section 141 away from the opening of the liquid storage tank 14, thereby avoiding the possibility of scalding accidents.

[0067] In one embodiment, the heating part 13 includes a heating wire, and a diameter D of the heating wire satisfies the following condition: D ≥ 0.1 mm.

[0068] Specifically, the diameter D of the heating wire can be 0.1 mm, or 0.2 mm, 0.3 mm, or 0.4 mm, or 0.5 mm, or 0.6 mm, or 0.7 mm, or 0.8 mm, or 0.9 mm, or 1 mm, etc.

[0069] This embodiment limits the diameter D of the heating wire to 0.1 mm or more, which can not only prevent the heating wire from being too small, reduce the probability of the heating wire being easily deformed and broken, and improve the reliability of the heating wire, but also prevent the heating wire from failing to shape the sealing portion 12, thereby reducing the difficulty of preparation.

[0070] Please refer to Figure 3 and Figure 6 In one embodiment, the distance H1 between the heating portion 13 and the bottom wall of the liquid storage tank 14 satisfies the following condition: H1 ≥ 0.5 mm.

[0071] Specifically, the distance H1 between the heating portion 13 and the bottom wall of the liquid storage tank 14 can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, 1.5 mm, 2 mm, etc.

[0072] This embodiment limits the spacing H1 between the heating part 13 and the bottom wall of the liquid storage tank 14 to ≥0.5mm. This can not only avoid the problem that the heating part 13 is easily exposed from the sealing part 12 during the preparation process due to the gap H1 being too small, but also can make the heating part 13 close to the bottom wall of the liquid storage tank 14, thereby improving the heat conduction effect of the heating part 13, thereby improving the defrosting and de-icing effect of the heating part 13.

[0073] Please refer to Figure 1-Figure 6 In one embodiment, the sealing portion 12 includes at least one sealing sub-portion, and the heating portion 13 is embedded in at least one of the sealing sub-portions; when there are multiple sealing sub-portions, the multiple sealing sub-portions are arranged at intervals along the extension direction of the main body 11.

[0074] For example, each sealing sub-section is embedded with a heating section 13. For another example, some sealing sub-sections are embedded with heating sections 13, and other sealing sub-sections are not embedded with heating sections 13. A plurality of sealing sub-sections are disposed on the main body 11 from top to bottom.

[0075] In summary, by setting at least one sealing sub-part, the present embodiment can embed a heating part 13 on the corresponding sealing sub-part according to user needs or product needs, which can not only improve the cleaning function of the sealing strip 1, but also expand the scope of application, improve the defrosting and deicing effect of the heating part 13, and achieve effective and accurate defrosting and deicing.

[0076] Please refer to Figure 1-Figure 6 In one embodiment, the sealing sub-portion includes a first sealing sub-portion 121 and a second sealing sub-portion 122 , and the heating portion 13 is embedded in the first sealing sub-portion 121 and the second sealing sub-portion 122 .

[0077] The liquid storage tank 14 includes a first storage sub-groove 143 and a second storage sub-groove 144, the main body 11, the first sealing sub-portion 121, and the vehicle peripheral part 2 form the first storage sub-groove 143, the main body 11, the second sealing sub-portion 122, the vehicle peripheral part 2 and the first sealing sub-portion 121 form the second storage sub-groove 144, and the heating part 13 is used to heat the first storage sub-groove 143 and the second storage sub-groove 144.

[0078] The first sealing sub-portion 121 is closer to the outside world than the second sealing sub-portion 122, which can also be understood as the first sealing sub-portion 121 and the second sealing sub-portion 122 are arranged on the main body 11 from top to bottom. Specifically, since the first sealing sub-portion 121 is closer to the outside world than the second sealing sub-portion 122, when the vehicle peripheral part 2 moves relative to the sealing strip 1, the liquid is more likely to accumulate in the first storage sub-groove 143, for example, most of the liquid accumulates in the first storage sub-groove 143, and a small amount of liquid accumulates in the second storage sub-groove 144; for another example, all the liquid accumulates in the first storage sub-groove 143.

[0079] The heating element provided in the first sealing sub-portion 121 is used to heat the first storage sub-slot 143, and the heating element provided in the second sealing sub-portion 122 is used to heat the second storage sub-slot 144. The heating element provided in the first sealing sub-portion 121 can be controlled to heat alone, or the heating element provided in the second sealing sub-portion 122 can be controlled to heat alone, or the heating element provided in the first sealing sub-portion 121 and the heating element provided in the second sealing sub-portion 122 can be controlled to heat at the same time. The user can adjust the heating element according to the needs of defrosting and deicing.

[0080] In summary, this embodiment can further improve the cleaning function of the sealing strip 1 by setting the first storage sub-groove 143 and the second storage sub-groove 144 to cooperate with each other, and by respectively setting heating elements on the first sealing sub-portion 121 and the second sealing sub-portion 122, the heating elements can realize deicing and defogging of the first storage sub-groove 143 and deicing and defogging of the second storage sub-groove 144, thereby further improving the defrosting and deicing effect of the heating portion 13.

[0081] Please refer to Figure 1-Figure 6 In one embodiment, the bottom wall of the first storage sub-groove 143 is set at an angle to the main body 11, and the bottom wall of the first storage sub-groove 143 includes an arc segment 141 and a first inclined sub-segment 1421, and the arc segment 141 is connected between the main body 11 and the first inclined sub-segment 1421, and the arc segment 141 is farther away from the opening of the first storage sub-groove 143 than the first inclined sub-segment 1421; the heating portion 13 provided in the first sealing sub-portion 121 is provided adjacent to the arc segment 141; or, the heating portion 13 provided in the first sealing sub-portion 121 is provided corresponding to the arc segment 141.

[0082] The bottom wall of the second storage sub-groove 144 is arranged at an angle with the main body 11, and the bottom wall of the second storage sub-groove 144 includes a second inclined sub-segment 1422 bent and connected to the main body 11, and the heating part 13 arranged in the second sealing sub-portion 122 is arranged adjacent to the second inclined sub-segment 1422; or, the heating part 13 arranged in the second sealing sub-portion 122 is arranged corresponding to the second inclined sub-segment 1422.

[0083] In summary, since liquid is more likely to accumulate in the first storage sub-groove 143, the shape of the first storage sub-groove 143 is optimized. The arc segment 141 can increase the contact area between the liquid in the first storage sub-groove 143 and the bottom wall of the first storage sub-groove 143, which is beneficial to quickly heating and evaporating the liquid. The first inclined sub-segment 1421 makes the liquid in the first storage sub-groove 143 tend to slide toward the arc segment 141 under the action of gravity, reducing the probability of liquid remaining in the first storage sub-groove 143, which is further beneficial to quickly heating and evaporating the liquid.

[0084] Furthermore, since only a small amount of liquid accumulates in the second storage sub-groove 144, the defrosting and de-icing of the second storage sub-groove 144 can be effectively achieved by bending the main body 11 and the second inclined sub-segment 1422, and the heating part 13 is arranged adjacent to or corresponding to the second inclined sub-segment 1422, and the arc segment 141 in the second storage sub-groove 144 can be omitted to reduce the difficulty of preparation.

[0085] Please refer to Figure 1-Figure 6 In one embodiment, the vehicle peripheral component 2 has an outer surface 21 facing the outside, and the heating portion 13 is disposed on the sealing portion 12 that abuts against the outer surface 21 .

[0086] Specifically, the sealing strip 1 includes an outer sealing strip 1a and an inner sealing strip 1b, wherein the sealing portion 12 of the outer sealing strip 1a abuts against the outer surface 21 of the vehicle peripheral component 2, and the sealing portion 12 of the inner sealing strip 1b abuts against the inner surface of the vehicle peripheral component 2. The sealing portion 12 of the outer sealing strip 1a is embedded with a heating portion 13, while the sealing portion 12 of the inner sealing strip 1b is not provided with a heating portion 13.

[0087] In summary, since water vapor condenses more easily on the outer surface 21 of the vehicle peripheral part 2 and less easily on the inner surface, the present embodiment realizes the function of rapid defrosting and deicing of the outer sealing strip 1a by arranging the heating portion 13 on the sealing portion 12 that abuts against the outer surface 21, thereby reducing costs and saving energy.

[0088] In one embodiment, the spacing H2 between the heating portion 13 and the outer surface 21 satisfies the following condition: H2 ≥ 1 mm. Specifically, the spacing H2 between the heating portion 13 and the outer surface 21 may be 1 mm, or 2 mm, 3 mm, or 4 mm, or 5 mm, or 6 mm, or 7 mm, or 8 mm, or 9 mm, or 10 mm, etc.

[0089] In this embodiment, by setting the spacing H2 between the heating part 13 and the outer surface 21 to be ≥1 mm, it is possible to avoid the gap between the heating part 13 and the vehicle peripheral part 2 being too small, causing the sealing part 12 to be unable to deform, and avoiding the vehicle peripheral part 2 causing large lifting resistance and difficulty in lifting.

[0090] Please refer to Fig. 9 In one embodiment, the sealing strip 1 further includes a first electrode 151 and a second electrode 152, one of the first electrode 151 and the second electrode 152 is a positive electrode, and the other is a negative electrode; the first electrode 151 and the second electrode 152 are arranged on the same side of the heating part 13, or the first electrode 151 and the second electrode 152 are respectively arranged on opposite sides of the heating part 13.

[0091] The heating part 13 is electrically connected to the positive and negative poles of the vehicle wires by connecting the first electrode 151 and the second electrode 152 to form a loop, and can be electrically heated. The voltage of the heating part 13 is equal to the voltage of the vehicle power supply, which can be 6V-48V. The first electrode 151 and the second electrode 152 are arranged on the same side of the heating part 13, which can also be understood as the positive and negative electrodes are arranged on a single side of the heating part 13. The first electrode 151 and the second electrode 152 are respectively arranged on opposite sides of the heating part 13, which can also be understood as the positive and negative electrodes are arranged on opposite sides of the heating part 13.

[0092] Among them, different resistances and powers can be matched by designing the heating part 13 with different cross-sections, so as to adjust the heating effect of the heating part 13 according to user needs and product requirements.

[0093] In one embodiment, the heating power density E of the heating unit 13 to the liquid storage tank 14 satisfies the following condition: E ≥ 450 W / m 2 .

[0094] Specifically, the heating power density E of the heating unit 13 to the liquid storage tank 14 can be 450 W / m 2 , or 475W / m 2 , or 500W / m 2 , or 525W / m 2 , or 550W / m 2 , or 575W / m 2 , or 600W / m 2 , or 650W / m 2 , or 700W / m 2 , or 800W / m 2 wait.

[0095] In this embodiment, the heating power density E of the heating unit 13 to the liquid storage tank 14 is limited to 450 W / m 2 , the accumulated water and ice in the liquid storage tank 14 can be quickly removed, the defrosting and deicing effect of the heating unit 13 is improved, and no excessive burden is imposed on the vehicle power supply, thereby ensuring the reliability of the vehicle.

[0096] Please refer to Figure 10-12 In one embodiment, there are multiple heating parts 13 , and the extension direction of each heating part 13 is the same as the extension direction of the sealing part 12 . The multiple heating parts 13 are arranged at intervals along the width direction of the sealing part 12 .

[0097] Optionally, the spacing between two adjacent heating parts 13 is not equal. Optionally, the spacing between at least some of the adjacent two heating parts 13 is equal. For example, the spacing between all the adjacent two heating parts 13 is not equal. For another example, the spacing between all the adjacent two heating parts 13 is equal. For another example, the spacing between some of the adjacent two heating parts 13 is not equal, and the spacing between another part of the adjacent two heating parts 13 is equal.

[0098] In summary, this embodiment limits the arrangement of the multiple heating parts 13 so that the multiple heating parts 13 heat the liquid storage tank 14 uniformly, thereby improving the uniformity of the heating parts 13 heating the liquid storage tank 14 and further improving the defrosting and deicing function of the heating parts 13.

[0099] Please refer to Figure 10-12 In one embodiment, a plurality of the heating units 13 are arranged in series; and / or a plurality of the heating units 13 are arranged in parallel.

[0100] For example, all the heating units 13 are arranged in series. For another example, all the heating units 13 are arranged in parallel. For another example, some of the heating units 13 are arranged in series, and another part of the heating units 13 are arranged in parallel. According to user needs and product needs, multiple heating units 13 can be arranged in series and / or in parallel, so that the sealing strip 1 is applicable to more scenarios.

[0101] The present application also provides a vehicle, which includes a vehicle peripheral component and a sealing strip as provided above in the present application, wherein a sealing portion of the sealing strip abuts against the vehicle peripheral component.

[0102] The vehicle provided in this embodiment adopts the sealing strip provided by the above application, and a heating part is embedded in the sealing part of the sealing strip. Specifically, when the vehicle peripheral parts move relative to the sealing strip, at least part of the liquid accumulates in the liquid storage tank; the heating part can heat the liquid storage tank to evaporate the liquid in the liquid storage tank, thereby realizing the defrosting and de-icing function of the sealing strip, avoiding the phenomenon that the liquid in the liquid storage tank condenses into ice and causes the vehicle peripheral parts to be unable to be used normally, thereby improving the reliability of the vehicle.
