TECHNICAL FIELD
[0001] The utility model relates to vehicle technical field especially relates to a door type clip and connecting piece. BACKGROUND
[0002] The automobile industry is currently in a period of great change and development. Traditional car companies are advancing boldly. For consumers, the automobile product consumer market has more choices, making consumers increasingly demanding of the quality and details of automobile products.
[0003] Among them, for the door type clip widely used in the connecting structure of automobile bumpers, wheel covers and other parts, the existing product assembly will cause the door type clip to deform, and the door type clip cannot rebound to the natural state, resulting in a loose clip condition, affecting the overall quality of the automobile product.

[0006] It should be noted that the clamping tongue is elastic. During the process of the door type clip extending into the cooperating hole, the inner wall of the cooperating hole will extrude the clamping tongue, so that the door type clip can pass through the cooperating hole. When the clamping tongue extends out of the cooperating hole, the clamping tongue will recover to its natural state (i.e. the state of the clamping tongue without force) under the action of elasticity, so that the clamping tongue can abut against the edge of the cooperating hole to limit the insertion direction of the door type clip.
[0007] The reset rib is also elastic. During the process of the clamping tongue extending into the cooperating hole, the clamping tongue is extruded and tilted. The reset rib is connected between the clamping tongue and the second frame, and the reset rib is stretched. When the clamping tongue extends out of the cooperating hole, the clamping tongue deforms towards its natural state. However, in actual use, the clamping tongue may not recover to the natural state, resulting in a loose clamping between the door type clip and the cooperating hole, affecting the quality of the assembled parts after the assembly of the body piece and the cooperating piece. By providing the reset rib, the reset rib can provide tension to the clamping tongue during the resetting process, helping the clamping tongue reset and ensuring the full rebound of the clamping tongue, reducing the condition that the clamping tongue cannot recover to the natural state, ensuring the stability of the abutment between the door type clip and the cooperating hole, and further ensuring the stability of the clamping between the body piece and the cooperating piece.
[0008] In some embodiments of the present application, the clamping tongue comprises opposite first and second surfaces, at least part of the first surface is convex to form a limiting convex in a direction away from the second surface, and the limiting convex is clamped with the matching part.
[0009] In some embodiments of the present application, the clamping tongue comprises a third surface opposite to the second frame, the third surface comprises a first end edge connected with the second surface; the second frame comprises a fifth surface and a sixth surface, the fifth surface is in the same direction as the second surface, and the sixth surface is opposite to the third surface, the sixth surface comprises a second end edge connected with the fifth surface; one end of the reset rib is connected with the first end edge, and the other end is connected with the second end edge.
[0010] In some embodiments of the present application, the third surface is coplanar with the side surface of the limiting convex toward the second frame, and the third surface extends obliquely toward the sixth surface in the direction of the first surface toward the second surface.
[0011] In some embodiments of the present application, the included angle between the third surface and the first surface is greater than or equal to 60° and less than or equal to 75°.
[0012] In some embodiments of the present application, the reset rib comprises a third end edge connected with the first end edge and a fourth end edge connected with the second end edge, and the length of the fourth end edge is greater than the length of the third end edge.
[0013] In some embodiments of the present application, the thickness of the reset rib is greater than or equal to 0.8 mm and less than or equal to 1.2 mm in the direction of the first surface toward the second surface.
[0014] In some embodiments of the present application, the first frame, the second frame, the clamping tongue and the reset rib are integrally formed.

[0027] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the accompanying drawings needed to be used in the embodiments or prior art description will be briefly introduced as follows. Obviously, those skilled in the art can obtain other drawings from these drawings without creative labor.
[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the examples in the specification are only some of the embodiments of the present application, not all the embodiments.
[0029] The automobile industry is currently in a period of great change and development. Traditional car companies are advancing boldly, and for consumers, the automobile product consumer market has more choices, making consumers' requirements for the quality and details of automobile products continue to improve.
[0030] Among them, for the door type clip widely used in the connection structure of automobile bumpers, wheel covers and other parts, the existing product assembly will cause the door type clip tongue to deform, which cannot rebound and cause the door type clip to be loose, affecting the overall quality of the automobile product.
[0031] To solve the above technical problems, the application provides a connecting piece applied to a vehicle, which can include a body piece, a matching piece and a door type clip 100, the door type clip 100 is arranged on the body piece, the matching piece is provided with a matching hole matched with the door type clip 100, and the connection between the body piece and the matching piece is realized through the cooperation between the door type clip 100 and the matching hole.
[0032] Specifically, the body piece can be the rear side wall of the vehicle, the matching piece can be the rear bumper support of the vehicle, the door type clip 100 is arranged on the rear side wall, and the door type clip 100 can be integrally formed with the rear side wall. The door type clip 100 extends into the matching hole on the rear bumper support to realize the connection between the rear side wall and the rear bumper support of the vehicle.
[0033] Among them, please refer to Figures 1 to 3 , the door type clip 100 can include a first frame 110, a second frame 120, a third frame 130 and a fourth frame 140, the first frame 110 and the second frame 120 are arranged opposite to each other, the third frame 130 and the fourth frame 140 are arranged opposite to each other, and the first frame 110, the third frame 130, the second frame 120 and the fourth frame 140 are connected in sequence to form a door type structure, wherein the second frame 120 is connected with the body piece, and the connection position of the first frame 110 and the third frame 130 and the connection position of the first frame 110 and the fourth frame 140 are formed as an angle.
[0034] It should be noted that when the door type clip 100 extends into the matching hole of the matching piece, the two ends of the first frame 110 extend into the matching hole first, and by setting the connection position of the first frame 110 and the third frame 130 and the connection position of the first frame 110 and the fourth frame 140 as an angle, the width of the free end of the door type clip 100 can be reduced, the interference of the door type clip 100 extending into the matching hole can be reduced, the assembly difficulty of the assembly personnel can be reduced, and the assembly efficiency can be improved.
[0035] In order to realize the clamping effect of the door-shaped clasp 100 and the matching hole, the door-shaped clasp 100 further comprises a clamping tongue 150 and a reset rib 160. The clamping tongue 150 is located between the first frame 110 and the second frame 120 and is connected with the first frame 110. The reset rib 160 is connected between the clamping tongue 150 and the second frame 120.
[0036] When the door-shaped clasp 100 is matched with the matching hole, the clamping tongue 150 abuts against the edge of the matching hole, thereby realizing the clamping cooperation between the body member and the matching member.
[0037] It should be noted that the clamping tongue 150 is elastic. During the process that the door-shaped clasp 100 is inserted into the matching hole, the inner wall of the matching hole will extrude the clamping tongue 150, so that the door-shaped clasp 100 can pass through the matching hole. When the clamping tongue 150 is stretched out of the matching hole, the clamping tongue 150 will restore its natural state (i.e. the state that the clamping tongue 150 is not forced) under the action of elasticity, so that the clamping tongue 150 can abut against the edge of the matching hole and provide the limit of the insertion direction of the door-shaped clasp 100 between the body member and the matching member.
[0038] The reset rib 160 is also elastic. During the process that the clamping tongue 150 is inserted into the matching hole, the clamping tongue 150 is extruded and deformed by tilting. The reset rib 160 is connected between the clamping tongue 150 and the second frame 120. The reset rib 160 is deformed by stretching. When the clamping tongue 150 is stretched out of the matching hole, the clamping tongue 150 deforms towards its natural state. However, in the actual use process, the clamping tongue 150 may not be able to restore to the natural state, which leads to the fact that the clamping between the door-shaped clasp 100 and the matching hole is not tight, thereby affecting the quality of the assembled member after the body member and the matching member are assembled.
[0039] By arranging the reset rib 160, the reset rib 160 can provide a pulling force to the clamping tongue 150 during the resetting process, thereby helping the clamping tongue 150 to reset and ensuring that the clamping tongue 150 fully pops out, reducing the situation that the clamping tongue 150 cannot return to the natural state, ensuring the stability of the abutment between the door-shaped clasp 100 and the matching hole, and further ensuring the stability of the clamping between the body member and the matching member.
[0040] For details, please refer to Figures 1 to 3 The clamping tongue 150 comprises a first surface 151 and a second surface 152 in the up-down direction. The clamping tongue 150 is provided with a limiting protrusion 153. The limiting protrusion 153 is protruded from at least part of the first surface 151 in a direction away from the second surface 152 (for example, the upward direction shown in Figure 1 Thus, the clamping tongue 150 realizes the clamping cooperation with the matching member through the limiting protrusion 153 on the clamping tongue 150.
[0041] In some embodiments of the present application, the card tongue 150 further comprises a third surface 154 opposite to the second frame 120, the third surface 154 comprising a first end edge connected with the second surface 152. The second frame 120 comprises a fourth surface, a fifth surface and a sixth surface, the fourth surface being the same as the first surface 151 (for example, upward as shown in Figure 1 Figure 1 the fifth surface being the same as the second surface 152 (for example, downward as shown in Figure 1 ), and the sixth surface being opposite to the third surface 154, the sixth surface comprising a second end edge connected with the fifth surface, one end of the reset rib 160 being connected with the first end edge and the other end being connected with the second end edge.
[0042] It should be noted that, referring to Figure 1 and Figure 2 , the reset rib 160 can be formed in a thin plate shape, the thickness of the reset rib 160 being less than the thickness of the card tongue 150 and the thickness of the second frame 120, by connecting the reset rib 160 between the first end edge and the second end edge, the recess formed by the card tongue 150, the reset rib 160 and the second frame 120 being upward, and the side surface of the reset rib 160 being downward being coplanar with the second surface 152 and the fifth surface.
[0043] In this way, during the forming of the card tongue 150, the reset rib 160 and the second frame 120 of the door-type card 100, only a forming block needs to be arranged in the opening direction of the recess corresponding to the reset rib 160, and the forming process is simple and the yield is high.
[0044] It should be noted that the first frame 110, the second frame 120, the card tongue 150 and the reset rib 160 are integrally formed, thereby ensuring the connection reliability of the first frame 110, the second frame 120, the card tongue 150 and the reset rib 160.
[0045] In some embodiments of the present application, referring to Figures 1 to 3 , in the direction of the first surface 151 toward the second surface 152 (for example, the direction from top to bottom as shown in Figure 1 ), the thickness of the reset rib 160 is greater than or equal to 0.8 mm and less than or equal to 1.2 mm.
[0046] In the specific implementation process, the thickness of the reset rib 160 can be 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm or 1.2 mm.
[0047] In this way, on the one hand, the reset rib 160 can be thin to ensure that the reset rib 160 has elasticity, and on the other hand, the reset rib 160 can be prevented from being too thin to affect the yield of the product.
[0048] In some embodiments of the present application, please refer to Figures 1 to 3 In the direction that the first surface 151 faces the second surface 152, the third surface 154 extends obliquely towards the sixth surface.
[0049] It should be noted that in the specific implementation process, the side surface of the limiting protrusion 153 facing the second frame 120 is coplanar with the third surface 154, when the body piece is used to disassemble the cooperating piece, the door-shaped clip 100 needs to be pulled out of the cooperating hole, by setting the third surface 154 as an inclined surface, the force received by the clamping tongue 150 in the pulling-out direction can be converted into the force of the clamping tongue 150 obliquely deforming when the door-shaped clip 100 is pulled out, so that the clamping tongue 150 can pass through the cooperating hole to realize the pulling-out of the door-shaped clip 100.
[0050] Among them, in order to ensure the limiting effect of the clamping tongue 150 and the guiding effect when pulling out the door-shaped clip 100 at the same time, in the specific implementation process, the angle between the third surface 154 and the first surface 151 is greater than or equal to 60° and less than or equal to 75°.
[0051] Specifically, the angle between the first surface 151 and the third surface 154 can be 60°, 62°, 64°, 66°, 68°, 70°, 72° or 75°.
[0052] In some embodiments of the present application, please refer to Figure 1 and Figure 2 The reset rib 160 can include a third end edge 161 connected to the first end edge and a fourth end edge 162 connected to the second end edge, and the length of the fourth end edge 162 is greater than the length of the third end edge 161.
[0053] It should be noted that the third end edge 161 is connected to the clamping tongue 150, the fourth end edge 162 is connected to the second frame 120, the clamping tongue 150 is located in the door-shaped structure surrounded by the first frame 110, the second frame 120, the third frame 130 and the fourth frame 140, and the width of the clamping tongue 150 is less than the width of the second frame 120, so in the specific implementation process, the maximum width of the third end edge 161 can be equal to the width of the first end edge, and the maximum width of the fourth end edge 162 can be equal to the width of the second frame 120.
[0054] Therefore, in the specific implementation process, the reset rib 160 can be set to a trapezoidal shape, which maximizes the connection length of the reset rib 160 between the clamping tongue 150 and the second frame 120, and further enhances the stability of the reset rib 160 during use.
[0055] In some other embodiments of the present application, the reset rib 160 can also be formed in a rectangular shape, i.e., the third end edge 161 has the same width as the fourth end edge 162.
[0056] In the door-shaped clip 100, the first frame 110, the second frame 120, the third frame 130, the fourth frame 140, the card tongue 150 and the reset rib 160 are all made of plastic material.
