[0023] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0024] The sealing strip 10 is widely used in vehicle doors, trunks, front hoods and other locations, and provides excellent sealing functions at the gaps in these locations. In the prior art, after the sealing strip 10 is assembled in the vehicle and subjected to extrusion, the compression load of the sealing strip 10 is not smooth, which will cause the sealing function of the sealing strip 10 to fail when the gap between the door and the sheet metal is too large, and the user needs to increase the closing force of the door when the gap between the door and the sheet metal is too small.

[0025] In view of the above problems, the present invention provides a sealing strip 10. Figure 1 , including a clamping member 11, a support bar assembly 12, a first support bar 13 and a second support bar 14.

[0026] The support bar assembly 12 is connected to the clamping member 11. Optionally, the clamping member 11 cooperates with the parts of the vehicle, and the clamping member 11 includes a clamping top edge 23, a clamping side edge 24 and a clamping bottom edge 25, and the bottom of the support bar assembly 12 is connected to the clamping top edge 23 as a whole. Optionally, the clamping member 11 also includes a core strip 27, which is bent and arranged inside the clamping top edge 23, the clamping side edge 24 and the clamping bottom edge 25. When the sealing strip 10 is squeezed, the core strip 27 provides a certain supporting force. Optionally, the clamping top edge 23, the clamping side edge 24 and the clamping bottom edge 25 enclose a clamping cavity with an open end, and the clamping member 11 also includes a plurality of lips 26, which are arranged at intervals on the clamping top edge 23 or the clamping bottom edge 25, and the plurality of lips 26 all extend into the clamping cavity. Optionally, when manufacturing the sealing strip 10 , the support strip assembly 12 and the clamping member 11 are integrally formed.

[0027] One end of the first support bar 13 is connected to the clamping member 11 , and the other end is connected to the support bar assembly 12 .

[0028] One end of the second support bar 14 is connected to one end of the first support bar 13 away from the clamping member 11 , and the other end is connected to the support bar assembly 12 . The second support bar 14 and the first support bar 13 have an included angle.

[0029] By arranging the clamping member 11, the support bar assembly 12, the first support bar 13 and the second support bar 14, the support bar assembly 12 is connected to the clamping member 11, one end of the first support bar 13 is connected to the clamping member 11, and the other end is connected to the support bar assembly 12, one end of the second support bar 14 is connected to the end of the first support bar 13 away from the clamping member 11, and the other end is connected to the support bar assembly 12, the second support bar 14 and the first support bar 13 have an angle, when the sealing strip 10 is squeezed, the first support bar 13, the second support bar 14 and the support bar assembly 12 will be deformed, because the second support bar 14 and the first support bar 13 have an angle, the elastic force is larger, thereby improving the pressure smoothness of the sealing strip 10.

[0030] In one embodiment, please refer to Figure 1 The clamping member 11 has a first opening, the first support bar 13 and the second support bar 14 form a second opening, and the opening directions of the first opening and the second opening are the same.

[0031] Specifically, the above arrangement improves the structure of the sealing strip 10 . After the sealing strip 10 is assembled, the directions of the elastic forces of the first support strip 13 and the second support strip 14 are appropriate, which is beneficial to improving the pressure smoothness of the sealing strip 10 .

[0032] In one embodiment, please refer to Figure 1The support bar assembly 12 includes a third support bar 121, a fourth support bar 122 and a first connecting bar 123 that are connected to each other. One end of the third support bar 121 is connected to the clamping member 11, and the other end is connected to the fourth support bar 122. One end of the first connecting bar 123 is connected to an end of the first support bar 13 away from the clamping member 11, and the other end is connected to an end of the third support bar 121 away from the clamping member 11.

[0033] Optionally, grooves may appear on the third support bar 121 and the fourth support bar 122 after being pressed, which is beneficial to the drainage of the sealing strip 10 .

[0034] Specifically, when the third support bar 121 or the fourth support bar 122 is squeezed, the first connecting bar 123 provides support force to the third support bar 121 or the fourth support bar 122, thereby reducing the possibility of overall structural collapse and permanent deformation.

[0035] In one embodiment, please refer to Figure 1 The support bar assembly 12 also includes a second connecting bar 124, one end of the second connecting bar 124 is connected to an end of the fourth support bar 122 away from the third support bar 121, and the other end is connected to an end of the second support bar 14 away from the first support bar 13.

[0036] Optionally, the second connecting strip 124 is in an arc shape, and the arc shape improves the aesthetics of the second connecting strip 124. The second connecting strip 124 protrudes toward a side away from the clamping member 11. Optionally, the second connecting strip 124 is a bubble tube.

[0037] Optionally, the second connecting strip 124 is chemically polished. The specific process is to use an oxidant solution to oxidize the surface of the second connecting strip 124 under certain conditions. The oxide layer can gradually dissolve into the solution. The micro-protrusions of the second connecting strip 124 are oxidized faster and more, while the micro-concave parts are oxidized slowly and less. Similarly, the oxide layer at the protrusions spreads more and faster than everywhere else and dissolves in the solution, so that the surface of the second connecting strip 124 is gradually flattened to prevent the rough surface of the second connecting strip 124 from scratching other parts when squeezed. Using chemical polishing to treat the second connecting strip 124 can protect the thin wall of the second connecting strip 124, avoid affecting the rigidity of the material, and make the second connecting strip 124 smooth and glossy. This type of polishing is simple to operate and has high processing efficiency.

[0038] Optionally, the second support bar 14, the first connecting bar 123, the fourth support bar 122 and the second connecting bar 124 enclose a deformation cavity, which can change when squeezed, thereby giving the second support bar 14, the first connecting bar 123, the fourth support bar 122 and the second connecting bar 124 a certain deformation space.

[0039] In one embodiment, please refer to Figure 1 The wall thickness of the first support bar 13 , the wall thickness of the second support bar 14 , the wall thickness of the third support bar 121 and the wall thickness of the fourth support bar 122 are all the same.

[0040] Optionally, the wall thickness of the first support bar 13, the wall thickness of the second support bar 14, the wall thickness of the third support bar 121 and the wall thickness of the fourth support bar 122 are all the same, and the preparation materials of the first support bar 13, the second support bar 14, the third support bar 121 and the fourth support bar 122 are also the same, so that the stiffness of the first support bar 13, the second support bar 14, the third support bar 121 and the fourth support bar 122 are all the same.

[0041] Specifically, the wall thickness of the first support bar 13, the wall thickness of the second support bar 14, the wall thickness of the third support bar 121 and the wall thickness of the fourth support bar 122 are all the same, so that when the first support bar 13, the second support bar 14, the third support bar 121 and the fourth support bar 122 are squeezed, there will be no large difference in deformation of the first support bar 13, the second support bar 14, the third support bar 121 and the fourth support bar 122.

[0042] Optionally, if different compressive force values ​​are encountered, the compressive force value may be adjusted by adjusting the wall thickness of the first support bar 13 , the wall thickness of the second support bar 14 , the wall thickness of the third support bar 121 , and the wall thickness of the fourth support bar 122 .

[0043] Specifically, the above arrangement can better solve the problem of uneven compression load of the sealing strip 10. When the above sealing strip 10 is used for a vehicle door, it solves the problem of sealing failure when the gap between the vehicle door and the sheet metal is too large, and the problem of increasing the closing force of the vehicle door when the gap between the vehicle door and the sheet metal is too small.

[0044] In one embodiment, please refer to Figure 1 There is a first angle A between the third support bar 121 and the fourth support bar 122, which satisfies: 90°≤A≤170°; and / or there is a second angle B between the first support bar 13 and the second support bar 14, which satisfies: 90°≤B≤170°.

[0045] Optionally, the first angle A may be, but is not limited to, 90°, 130°, 150°, and 170°. Optionally, the above angles may be set so that the third support bar 121 and the fourth support bar 122 can buffer and effectively share the pressure when being squeezed.

[0046] Specifically, when different compressive force values ​​are required, the compressive force value can be adjusted by adjusting the angle of the first angle A to adapt to the requirements of different vehicle models while meeting the requirements of compressive smoothness.

[0047] Optionally, the second angle B may be, but is not limited to, 90°, 130°, 150°, and 170°. Optionally, the above angles may be set so that the first support bar 13 and the second support bar 14 can buffer and effectively share pressure when being squeezed.

[0048] Specifically, when different compressive force values ​​are required, the compressive force value can be adjusted by adjusting the angle of the second angle B to adapt to the requirements of different vehicle models while meeting the requirements of compressive smoothness.

[0049] In one embodiment, please refer to Figure 1 , the angle of the second angle B is the same as the angle of the first angle A.

[0050] Optionally, during compression, the above arrangement ensures that the elastic forces generated by material deformation on the supporting structures on both sides are the same. This structure can make the compressive force value increase more slowly after crushing, and the smoothness of the compression load can be achieved by using this structure.

[0051] Optional, please refer to Figure 1 The first support bar 13, the third support bar 121, the first connecting bar 123 and the surface of the clamping member 11 facing the first connecting bar 123 enclose a buffer cavity 20, and the surface of the clamping member 11 facing the first connecting bar 123 is provided with a protrusion 21, and the protrusion 21 extends into the buffer cavity 20.

[0052] Optionally, when at least one of the first support bar 13, the third support bar 121 and the first connecting bar 123 is squeezed, at least one of the first support bar 13, the third support bar 121 and the first connecting bar 123 may extend into the buffer cavity 20, thereby playing a certain buffering function.

[0053] Optionally, a recessed portion may be provided on the surface of the clamping member 11 facing the first connecting strip 123 , and the recessed portion is connected to the raised portion 21 .

[0054] Specifically, when the sealing strip 10 is squeezed, the raised portion 21 can prevent the sealing strips 10 from sticking to each other. Optionally, a recessed portion can be provided on the surface of the clamping member 11 facing the first connecting strip 123, and the recessed portion is connected to the raised portion 21, thereby increasing the anti-sticking effect between the internal supporting structures of the sealing strip 10.

[0055] Optional, please refer to Figure 1 The number of the protrusions 21 is multiple, and the multiple protrusions 21 are arranged at intervals.

[0056] Optionally, when the sealing strip 10 is squeezed, the plurality of raised portions 21 increase the anti-adhesion effect between the internal supporting structures of the sealing strip 10. Optionally, the surface of the clamping member 11 facing the first connecting strip 123 may also be provided with a plurality of recessed portions, and each raised portion 21 is provided between two adjacent recessed portions. Specifically, the above arrangements all increase the anti-adhesion effect between the internal supporting structures of the sealing strip 10.

[0057] In one embodiment, please refer to Figure 1 There is a third angle C between the first support bar 13 and the surface of the clamping member 11, which satisfies: 90°≤C≤170°; and / or there is a fourth angle D between the second support bar 14 and the surface of the clamping member 11, which satisfies: 90°≤D≤170°.

[0058] Optionally, the surface of the clamping member 11 is the surface of the clamping top edge 23 facing the first connecting strip 123. Optionally, the above angle setting can make the first support strip 13 and the surface of the clamping member 11 buffer and effectively share the pressure when being squeezed.

[0059] Optionally, the third angle C may be, but is not limited to, 90°, 130°, 150° and 170°.

[0060] Specifically, when different compressive force values ​​are required, the compressive force value can be adjusted by adjusting the angle of the third angle C to adapt to the requirements of different vehicle models while meeting the requirements of compressive smoothness.

[0061] Optionally, the surface of the clamping member 11 is the surface of the clamping top edge 23 facing the first connecting strip 123. Optionally, the above angle setting can make the second support strip 14 and the surface of the clamping member 11 buffer and effectively share the pressure when being squeezed.

[0062] Optionally, the fourth angle D may be, but is not limited to, 90°, 130°, 150° and 170°.

[0063] Optionally, the third angle C and the fourth angle D have the same direction, and the angle of the third angle C is the same as the angle of the fourth angle D, so that when the first support bar 13, the second support bar 14, the third support bar 121 and the fourth support bar 122 are squeezed, the directions of the elastic forces formed are close, which is beneficial to improving the pressure smoothness of the sealing strip 10.

[0064] Specifically, when different compressive force values ​​are required, the compressive force value can be adjusted by adjusting the angle of the fourth angle D to adapt to the requirements of different vehicle models while meeting the requirements of compressive smoothness.

[0065] It should be noted that, in the present invention, optionally, the material of the clamping member 11 may be a thermoplastic elastomer, specifically thermoplastic vulcanized rubber, but the type of the material of the clamping member 11 is not limited.

[0066] In one embodiment, please refer to Figure 1 The sealing strip 10 further includes an auxiliary support strip 22 , one end of which is connected to the second support strip 14 , and the other end of which is connected to the clamping member 11 .

[0067] Optionally, the auxiliary support bar 22 is a bubble tube. Optionally, the auxiliary support bar 22 plays a role of auxiliary support. Optionally, the auxiliary support bar 22 is in an arc shape, which improves the aesthetics of the auxiliary support bar 22, and the auxiliary support bar 22 protrudes toward the side away from the support bar assembly 12.

[0068] Optionally, the auxiliary support bar 22 is polished, and the polishing method may be fluid polishing, mechanical polishing, ultrasonic polishing, chemical polishing, electrolytic polishing, etc. Polishing the auxiliary support bar 22 improves the smoothness and glossiness of the auxiliary support bar 22 and avoids scratching other components.

[0069] Optionally, the first support bar 13 , the second support bar 14 and the auxiliary support bar 22 enclose a variable cavity, and when squeezed, the variable cavity can change, thereby providing the first support bar 13 , the second support bar 14 and the auxiliary support bar 22 with a certain deformation space.

[0070] The embodiment of the utility model further provides a vehicle, comprising the aforementioned sealing strip 10 .
