Description

Technical Field

[0001] This disclosure generally relates to the field of metal skeleton technology, and specifically to a roll shearing tension misaligned metal skeleton and sealing strip. Background Technology

[0002] Engine compartments, luggage compartments, and door openings of vehicles, ships, and airplanes are all equipped with sealing strips. Taking automotive sealing strips as an example, they mainly consist of a metal frame and an outer layer of sealing plastic material. Before or after being wrapped with the sealing material, the metal frame is bent into a U-shaped clamping structure, clamping onto the sealing flange of the opening to provide support and reduce deformation of the sealing strip. For example, the traditional process for automotive door inner and outer water-cutting sealing strips and glass guide channel sealing strips uses a steel strip as the metal frame, and then applies a coating of sealing plastic material to the surface of the steel strip to form the sealing strip.

[0003] The utility model patent with authorization announcement number CN 209892738 U discloses a metal frame for sealing strips. Cutting slits on both sides of the metal frame can improve flexibility. However, this method can only improve the flexibility of the two sides of the metal frame, but cannot improve the flexibility of the main body of the metal frame. It is not convenient to bend the position of the central axis of the metal frame. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a roll shearing stretch misaligned metal skeleton and sealing strip to solve the above problems.

[0005] The first aspect of this application provides a roll-shear stretch misaligned metal skeleton, comprising:

[0006] A substrate, the central axis of which extends along a first direction, and multiple toothed wings arranged along the first direction are formed on both sides of the substrate. An edge cut is formed between two adjacent toothed wings on the same side of the substrate, and the edge cut extends to the central axis. The toothed wings on both sides of the substrate are staggered along the first direction so that the edge cuts on both sides of the substrate form a bridging structure at the central axis position.

[0007] According to the technical solution provided in the embodiments of this application, the edge cut includes:

[0008] A pair of first sidewalls, the pair of first sidewalls extending along a second direction and parallel to each other, the second direction being perpendicular to the first direction;

[0009] A pair of second sidewalls are respectively disposed at one end of a pair of first sidewalls near the central axis, and the ends of the pair of second sidewalls near the central axis intersect to form a V-shaped structure.

[0010] According to the technical solution provided in the embodiments of this application, the two second sidewalls that are close to each other in adjacent edge cuts are parallel to each other, and the distance between the two second sidewalls that are close to each other in all adjacent edge cuts is equal.

[0011] According to the technical solution provided in the embodiments of this application, the toothed wing is provided with a dividing cut, the dividing cut extends along the second direction, and the dividing cut divides the toothed wing into a first sub-wing and a second sub-wing that are independent of each other.

[0012] According to the technical solution provided in the embodiments of this application, the dividing cut on one side of the substrate corresponds one-to-one with the edge cut on the other side, and the dividing cut and the corresponding edge cut are collinear.

[0013] A second aspect of this application provides a sealing strip, comprising a roll-shear-stretch-misaligned metal skeleton as described above, and a sealing material wrapped around the outside of the metal skeleton.

[0014] According to the technical solution provided in the embodiments of this application, the sealing material is made of plastic.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: By setting multiple toothed wings on both sides of the substrate and forming edge cuts between the toothed wings, the plastic material can pass through and fill the edge cuts when making the sealing strip, thereby making the edge of the metal skeleton more firmly bonded to the plastic material; since the toothed wings on both sides of the substrate are arranged in an alternating manner and the edge cuts extend to the central axis position, on the one hand, each toothed wing has a greater degree of freedom, thereby allowing the metal skeleton to be bent into more complex shapes when making the sealing strip, and also increasing the degree of freedom of the central axis position of the substrate, making it easier to bend the central axis position of the substrate; on the other hand, the metal skeleton is connected through the bridging structure formed by the edge cuts, the bridging structure has strong tensile strength, and since adjacent toothed wings are only connected through the bridging structure, it is convenient to cut the sealing strip into different lengths when making the sealing strip.

[0019] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example 1

[0022] Please refer to Figure 1 This application provides a roll-shear-stretch misaligned metal skeleton, comprising:

[0023] A base 1, the central axis 2 of the base 1 extends along a first direction, and a plurality of toothed wings 3 are formed on both sides of the base 1 arranged along the first direction. An edge cut 4 is formed between two adjacent toothed wings 3 on the same side of the base 1, and the edge cut 4 extends to the central axis 2. The toothed wings 3 on both sides of the base 1 are staggered along the first direction so that the edge cut 4 on both sides of the base 1 forms a bridging structure at the position of the central axis 2.

[0024] Specifically, the substrate 1 is a metal sheet, with the first direction being... Figure 1 In the vertical direction, multiple toothed wings 3 are formed on both sides of the central axis 2 on the base 1. The toothed wings 3 extend outward in a direction perpendicular to the central axis 2. By bending the toothed wings 3 to different degrees, different shapes can be formed for the metal skeleton. An edge cutout 4 is cut between adjacent toothed wings 3. The edge cutout 4 allows plastic material to pass through when making the sealing strip, and the plastic material fills the edge cutout 4, thereby making the edge of the metal skeleton more firmly bonded to the plastic material. All the edge cutouts 4 on the metal skeleton have the same width.

[0025] The edge cut 4 extends to the position of the central axis 2. The toothed wings 3 on one side of the base 1 are staggered relative to the toothed wings 3 on the other side. On this basis, the edge cuts 4 on both sides of the base 1 are also staggered. In the extension direction of the central axis 2, two adjacent edge cuts 4 and the base 1 between them form a bridging structure. That is, multiple toothed wings 3 on both sides of the base 1 are connected by multiple bridging structures. The bridging structure connection improves the tensile strength of the toothed wings 3. At the same time, extending the edge cut 4 to the position of the central axis 2 also makes the bending degree of each toothed wing 3 greater, so that the metal skeleton can be bent into more complex shapes to adapt to various irregular sealing strips. In addition, compared with the traditional case where the metal skeleton is filled with the base 1 at the position of the central axis 2, since two adjacent toothed wings 3 are only connected by bridging structures, the metal skeleton provided in this embodiment is convenient to cut into sealing strips after being made into sealing strips.

[0026] Furthermore, the edge cut 4 includes:

[0027] A pair of first sidewalls 5, the pair of first sidewalls 5 extending along a second direction and parallel to each other, the second direction being perpendicular to the first direction;

[0028] A pair of second sidewalls 6 are respectively disposed at one end of a pair of first sidewalls 5 near the central axis 2, and the ends of the pair of second sidewalls 6 near the central axis 2 intersect to form a V-shaped structure.

[0029] Specifically, the second direction is Figure 1 In the horizontal direction, since the pair of first sidewalls 5 of each edge cut 4 are parallel to each other, and the pair of second sidewalls 6 of each edge cut 4 intersect to form a V-shaped structure, the toothed wings 3 have the same width at the position away from the central axis 2 and the width increases at the end closer to the central axis 2. This arrangement increases the connection area of ​​two adjacent toothed wings 3 at the connection position, thereby making the adjacent bridging structures arranged in an S-shape, and allowing the toothed wings 3 to be adjusted to a greater extent while ensuring the connection strength.

[0030] Furthermore, the two adjacent second sidewalls 6 in the adjacent edge cuts 4 are parallel to each other, and the distance between the two adjacent second sidewalls 6 in all adjacent edge cuts 4 is equal.

[0031] For details, please refer to Figure 1In the extending direction of the central axis 2, since the two adjacent second sidewalls 6 in the adjacent edge cuts 4 are parallel to each other, and the distance between the two adjacent second sidewalls 6 in all adjacent edge cuts 4 is equal, the width of each of the bridging structures is equal at each position, and the width of all bridging structures is equal. This arrangement makes the metal skeleton uniform in strength at each bridging structure position, so that there is no limitation on the cutting position when making the sealing strip and cutting it.

[0032] Furthermore, the toothed wing 3 is provided with a dividing cut 7, which extends along the second direction and divides the toothed wing 3 into a first sub-wing 8 and a second sub-wing 9 that are independent of each other.

[0033] Specifically, the dividing cut 7 is located in the middle of the toothed wing 3. By cutting the dividing cut 7 on the toothed wing 3, the toothed wing 3 is divided into two parts: the first sub-wing 8 and the second sub-wing 9. The first sub-wing 8 and the second sub-wing 9 can be combined together to form the toothed wing 3, or they can be separated and bent and shaped separately. When the first sub-wing 8 and the second sub-wing 9 are separated, the metal frame has better shaping freedom. Among two adjacent toothed wings 3, the first sub-wing 8 of one toothed wing 3 and the second sub-wing 9 of the other toothed wing 3 can be regarded as two adjacent toothed wings 3 with smaller volume.

[0034] Furthermore, the dividing cut 7 on one side of the substrate 1 corresponds one-to-one with the edge cut 4 on the other side, and the dividing cut 7 and the corresponding edge cut 4 are collinear.

[0035] Specifically, since the dividing cut 7 on one side of the base 1 corresponds one-to-one with the edge cut 4 on the other side, and since the dividing cut 7 is located in the middle of the toothed wing 3, the dividing cut 7 and the corresponding edge cut 4 are collinear, thus ensuring that all the first sub-wings 8 and second sub-wings 9 on the metal frame have the same width, guaranteeing the uniformity of the structure at each position of the metal frame. The distance between the ends of the dividing cut 7 and the edge cut 4 that are close to each other is greater than half the width of the toothed wing 3, that is, the distance between the ends of the dividing cut 7 and the edge cut 4 that are close to each other is greater than the width of the first sub-wing 8 and the second sub-wing 9. Because stress is concentrated at the smaller width position, this arrangement ensures that when the metal frame is stretched, the stress is concentrated on the first sub-wing 8 or the second sub-wing 9, avoiding stress concentration at the connection position between the ends of the dividing cut 7 and the edge cut 4 that could cause the metal frame to break.

[0039] Specifically, the plastic material is preferably EPDM rubber, but other rubbers may also be selected.
