[0038] Figure 1A-1E Fasteners are used to connect two parts, such as connecting a vehicle's interior panel to a sheet metal. Figure 1A-1E As shown, the fastener 100 includes a support disk 102, a connecting portion 130, a sealing portion 150 and an operating portion 180. The support disk 102 is generally in the shape of a circular plate and has a central axis X1. In the axial direction of the support disk 102, the support disk 102 has a first side 121 and a second side 122 that are arranged opposite to each other, and the surface of the first side 121 and the surface of the second side 122 both extend along the radial direction of the support disk 102. The connecting portion 130 is connected to the middle part of the first side 121 of the support disk 102 and extends along the axial direction of the support disk 102. The sealing portion 150 is connected to the circumferential edge 190 of the support disk 102 and extends in a direction away from the connecting portion 130. The operating portion 180 is connected to the second side 122 of the support disk 102 and is used to cooperate with a screwing tool to rotate the fastener 100. The screwing tool can be a tool such as a wrench or a screwdriver, or a robot with a corresponding shape.

[0039] In use Figure 1AThe fastener in the embodiment connects two components, the fastener 100 is pre-installed on the first component, and then the fastener connected with the first component is installed in the second component, so that the fastener 100 connects the first component and the second component. When the fastener 100 connects the first component and the second component, the sealing portion 150 of the fastener 100 cooperates with the corresponding position of the first component, so that a seal is formed between the fastener 100 and the first component.

[0040] like Figure 1A-1E As shown, the sealing portion 150 includes a side wall 151 and an extension portion 152. The proximal end 156 of the side wall 151 is connected to the edges of the supporting disk 102. In one embodiment of the present application, the side wall 151 extends outwardly in a direction away from the connecting portion 130 of the supporting disk 102, that is, it extends in a direction away from the central axis X1 along the axial direction of the supporting disk 102. In another embodiment of the present application, the side wall 151 extends in the axial direction of the supporting disk 102. The extension portion 152 is connected to the distal end 157 of the side wall 151 and extends outwardly in a direction away from the supporting disk 102, that is, it extends in a direction away from the central axis X1 along the axial direction of the supporting disk 102. In the axial direction of the supporting disk, the height of the extension portion 152 does not exceed the supporting disk 102, that is, there is a distance between the distal end of the extension portion 152 and the supporting disk 102, and the height of the extension portion 152 is not less than 1 / 3 of the height of the side wall 151. The thickness of the extension 152 is less than the thickness of the side wall 151, and the thickness of the distal end of the extension 152 is less than the thickness of the proximal end of the extension 152. A receiving groove 155 is formed between the extension 152 and the side wall 151, and the opening 159 of the receiving groove 155 faces the plane where the support plate 102 is located. The receiving groove 155 is used to accommodate the corresponding part of the first component. The thickness of the receiving groove 155 gradually increases in the direction from the connection between the extension 152 and the side wall 151 to the opening 159, so as to facilitate guiding the corresponding parts of the first component into the receiving groove 155. The connection between the extension 152 and the side wall 151 has a smooth transition.

[0041] like Figure 1A-1EAs shown, the connection portion 130 extends from the middle of the first side 121 of the support plate 102 in the axial direction. The connection portion 130 includes a locking portion 160 and a pair of elastic arms 171 and 172. The locking portion includes a pair of first side portions 161 and 162 arranged opposite to each other, and a pair of second side portions 163 and 164 arranged opposite to each other. One end of the first side portions 161 and 162 is connected to the first side 121 of the support plate 102, and the other end has a pair of protrusions 191 and 192 protruding outward from the outer surface of the first side portions 161 and 162. The protrusions 191 and 192 respectively have a pair of inclined surfaces 168 and 169 facing the support plate 102. The inclined surface 168 has a top 195 and a bottom 196, and the inclined surface 168 extends obliquely in a direction away from the support plate 102 in the direction from the second side portion 163 to the second side portion 164, that is, the top 195 is close to the second side portion 163, and the bottom 196 is close to the second side portion 164. The inclined surface 169 has a top 197 and a bottom 198, and the inclined surface 169 extends obliquely in a direction toward the support plate 102 in the direction from the second side portion 163 to the second side portion 164, that is, the bottom 198 is close to the second side portion 163, and the top 197 is close to the second side portion 164. That is, the inclined surfaces 168 and 169 are inclined in opposite directions in the direction from the second side portion 163 to the second side portion 164. The inclined surfaces 168 and 169 cooperate with the support plate 102 to clamp the first component and the second component to be connected. The inclined surfaces 168 and 169 have a spacing from the first side 121 of the support plate 102 , which spacing is dependent on the thickness of the first component and the second component to be connected.

[0042] The connecting portion 130 further includes a pair of retaining arms 171 and 172, which are arranged on the outer sides of a pair of second side portions 163 and 164 and have a spacing between the second side portions 163 and 164. The retaining arms 171 and 172 are used to retain the fastener in the first component. The proximal ends of the retaining arms 171 and 172 are connected to the first side 121 and the second side portion 163 of the support disk 102, and the distal ends can be deflected toward the locking portion 160. The outer sides of the retaining arms 171 and 172 include first recesses 191 and 193 arranged along the axial direction of the support disk 102, and main body sections 187 and 188. In one embodiment of the present application, the main body sections 187 and 188 include second recesses 192 and 194, respectively. The first recesses 191 and 193 are closer to the support disk 102 than the second recesses 192 and 194. The first recesses 191 and 193 include upper guide surfaces 136 and 137, which are located at one end of the first recesses 191 and 193 away from the support plate 102, and the upper guide surfaces 136 and 137 extend obliquely away from each other in a direction away from the support plate 102. The second recesses 192 and 194 include lower guide surfaces 138 and 139, and stop surfaces 146 and 147. The lower guide surfaces 138 and 139 are located at one end of the second recesses 192 and 194 close to the support plate 102, and the stop surfaces 146 and 147 are located at one end away from the support plate 102. The lower guide surfaces 138 and 139 extend obliquely toward each other in a direction away from the support plate 102, and the stop surfaces 146 and 147 extend substantially parallel to the support plate 102.

[0043] After the fastener 100 is loaded into the first component, the fastener 100 can move relative to the first component. The first recesses 191 and 193 are used to pre-install the fastener in the first component so that the matching portion of the first component is retained in the first recesses 191 and 193. During the installation of the fastener, if the connecting portion 130 is subjected to a corresponding external force, the fastener can move relative to the first component so that the matching portion of the first component enters the second recesses 192 and 194. The angle between the upper guide surfaces 136 and 137 and the lower guide surfaces 138 and 139 and the extension direction of the support plate 102 is greater than 45°, and the upper guide surfaces 136 and 137 and the lower guide surfaces 138 and 139 are used to guide the corresponding matching portion of the first component to move between the first recesses 191 and 193 and the second recesses 192 and 194. The limiting surfaces 146 and 147 are used to prevent the fastener 100 from leaving the first component. A transition portion 166 is formed between the upper guide surface 136 and the lower guide surface 138, and a transition portion 167 is formed between the upper guide surface 137 and the lower guide surface 139. The transition portion 166 forms a smooth transition with the upper guide surface 136 and the lower guide surface 138, and the transition portion 167 forms a smooth transition with the upper guide surface 136 and the lower guide surface 139, thereby facilitating the fastener 100 to slide between the first recesses 191, 193 and the second recesses 192 and 194 relative to the first component. The main body section 187 includes the transition portion 166 and the second recess 192, and the main body section 188 includes the transition portion 167 and the second recess 194.

[0044] In another embodiment of the present application, the main body sections 187 and 188 are smooth surfaces without recessed portions.

[0045] The holding arm 171 and the holding arm 172 are symmetrically arranged with respect to the central axis of the support plate 102. The holding arm 171 includes a fixed portion 175 and a movable portion 176, wherein the fixed portion 175 is connected to the second side portion 163 and the first side 121 of the support plate 102. The fixed portion 175 has an outer portion 144 away from the second side portion 163, and the movable portion 176 is connected to the outer portion 144 of the fixed portion 175 and extends in a direction away from the support plate 102. There is a gap between the movable portion 176 and the second side portion 163, and a step surface 145 is formed between the movable portion 176 and the fixed portion 175, and the step surface 145 is located between the second side portion 163 and the proximal end of the movable portion 176. That is, in the direction from the second side portion 163 to the second side portion 164, the thickness of the fixed portion 175 is greater than the thickness of the movable portion 176. Similarly, the holding arm 172 includes a fixed portion 177 and a movable portion 178.

[0046] The movable portions 176 and 178 can deflect toward the second side portions 163 and 164. The lengths of the fixed portions 175 and 177 in the axial direction of the support plate 102 can be adjusted according to the elastic force required by the movable portion 176. When the lengths of the fixed portions 175 and 177 increase, a greater force needs to be applied to the movable portion 176 to deform it. In other words, when the lengths of the fixed portions 175 and 177 increase, the pull-out force of the fastener relative to the first component is greater.

[0047] The connection portion 130 further includes limiting portions 185 and 186. The limiting portion 185 extends from the first side portion 161 toward the fixed portion 175 of the elastic arm 171 and is connected to the fixed portion 175. The upper portion of the limiting portion 185 is connected to the support plate 102, and the lower portion is substantially flush with the fixed portion 175. Similarly, the limiting portion 186 extends from the inside of the first side portion 162 toward the fixed portion 177 of the elastic arm 172 and is connected to the fixed portion 177. The upper portion of the limiting portion 186 is connected to the support plate 102, and the lower portion is substantially flush with the fixed portion 177. In other words, the limiting portion 185 and the limiting portion 186 are both connected to the movable portion of the corresponding retaining arm and the support plate 102, so that the connection portion 130 has a certain strength at the limiting portions 185 and 186, and is not easily damaged when the limiting portions 185 and 186 are subjected to a force in the rotation direction. The limiting portions 185 and 186 are used to prevent the fastener from further over-rotating when the fastener is rotated into place.

[0048] The fastener 100 also includes an operating portion 180, which is connected to the second side 122 of the support disk 102 and is surrounded by the sealing portion 150. The operating portion 180 has a side wall 182 extending along the circumferential direction, and the side wall 182 includes a matching portion 189, and the matching portion 189 can be matched with a screwing tool so that the screwing tool can drive the fastener to rotate. In one embodiment of the present application, the outer contour of the side wall 182 is a hexagonal prism, and the matching portion 189 includes six planes, which can be matched with a hexagonal wrench. In another embodiment of the present application, the matching portion 189 includes at least one pair of planes, which can be matched with pliers or clamps. In the present application, the outer contour of the side wall 182 is an anti-rotation shape, which can be matched with a tool with a matching shape to rotate with the tool, for example, the cross section of the operating portion is a polygon, a plum blossom or an irregular shape. In one embodiment of the present application, the outer contour of the operating portion 180 is a hexagon. The operating portion 180 further includes an operating slot 183, the inner side wall of which has a plurality of recesses. In one embodiment of the present application, the cross section of the operating slot 183 is plum blossom-shaped, which can be matched with a correspondingly shaped screwing tool (e.g., a screwdriver). In another embodiment of the present application, the inner side wall of the operating slot 183 has a plurality of planes, forming a prism shape, which can be matched with a correspondingly shaped wrench.

[0049] The inner side wall 199 of the operation groove 183 and the outer side of the operation portion 180 surround the annular portion 149, and the annular portion 149 has a plurality of grooves 148, and the plurality of grooves 148 extend from the end surface of the annular portion 149 toward the support disk along the axial direction of the support disk 102. The plurality of grooves 148 are evenly distributed along the circumferential direction. The plurality of grooves 148 can reduce the shrinkage problem that may be generated in the molding process of the annular portion 149, and can enhance the strength of the annular portion 149.

[0050] In another embodiment of the present application, the operating portion 180 does not include the operating groove 183 , and a plurality of grooves 148 are evenly arranged in the operating portion 180 .

[0052] like Figure 2A and Figure 2B As shown, a receiving groove 155 is formed between the side wall 151 and the extension portion 152, and the thickness of the receiving groove 155 gradually increases from the bottom opening to form a trumpet shape, so as to facilitate guiding the corresponding part of the first component into the receiving groove 155. The receiving groove 155 has a first contact surface 208 and a second contact surface 209. The first contact surface 208 is formed by the side wall 151, and the first contact surface 208 is arranged toward the extension portion 152, and extends obliquely along the direction away from the second side 122 of the support disk 102 and away from the central axis of the support disk. The second contact surface 209 is formed by the extension portion 152, and the second contact surface 209 is arranged toward the side wall 151, and extends obliquely along the direction toward the second side 122 of the support disk 102 and away from the central axis of the support disk. The first contact surface 208 and the second contact surface 209 are used to cooperate with the corresponding part of the first component, so that a seal is formed between the fastener 100 and the first component.

[0053] Each of the first holding arms 171 and 172 has a spacing from the locking portion 160 so as to be deflectable toward the locking portion 160 .

[0054] A plurality of grooves 148 extend from the end surface of the operating portion 180 in a radial direction toward the support disk 102, and exceed the surface of the second side 122 of the support disk 102. In one embodiment of the present application, the grooves 148 are cylindrical. In other embodiments of the present application, the grooves may be prismatic, trumpet-shaped, conical, or other shapes. Along the radial direction of the support disk, the maximum thickness of the grooves 148 is not less than 1 / 2 of the average thickness of the annular portion 149. In one embodiment of the present application, the maximum thickness of the grooves 148 is not less than 2 / 3 of the average thickness of the annular portion 149. In other words, the grooves 148 have a certain thickness, which can improve the problem of voids caused by material collapse during the molding process.

Figure 4A and Figure 4B As shown, the first component 301 is generally plate-shaped and has a first side 411 and a second side 412 that are oppositely disposed. The first opening 331 is generally rectangular and penetrates the first side 411 and the second side 412. The first side 411 includes a flange portion 460 surrounding the first opening 331, and the flange portion 460 is higher than the surface of the first side 411. The first opening 331 has a pair of length side edges 421 and 422, and a pair of width side edges 423 and 424. When the fastener 100 is inserted into the first opening 331, the length side edges 421 and 422 correspond to the second side edges 163 and 164 of the locking portion 160, and the width side edges 423 and 424 correspond to the first side edges 161 and 162 of the locking portion 160.

[0057] The first component 301 further includes a pair of receiving portions 436 and 437, which are recessed from the end surface of the flange portion 460 toward the second side 412 and have a spacing therebetween. The pair of receiving portions 436 and 437 are respectively located at the length side edges 421 and 422 and communicate with the first opening 331. The pair of receiving portions 436 and 437 are used to receive the pair of retaining arms 171 and 172 of the fastener 100. Connecting mating portions 441 and 442 are formed between the bottom of the receiving portions 436 and 437 and the second side 412, and the connecting mating portions 441 and 442 can be matched with the first recesses 191 and 193 and the second recesses 192 and 194 of the retaining arms 171 and 172.

[0058] The first component 301 further includes a sealing mating portion 450, which has an annular wall 451, a first end of which is connected to the second side 412 of the first component 301 and is disposed around the first opening 331. The diameter of the annular wall 451 matches the size of the sealing portion 150 of the fastener 100, so that the second end of the annular wall 451 can enter the receiving groove 155 of the sealing portion 150 and contact the first contact surface 208 and / or the second contact surface 209, so that a seal is formed between the sealing mating portion 450 and the sealing portion 150.

[0059] Figure 5A is a cross-sectional view of the fastener in the pre-installed position in the first component, Figure 5B is a cross-sectional view of the fastener when it leaves the pre-installed position in the first component. Figure 5A As shown, when the fastener 100 is inserted into the first opening 331 from the second side 412 of the first component and reaches the pre-installed position, the sealing mating portion 450 enters the receiving groove 155 of the fastener 100; the connecting mating portions 441 and 442 of the first component 301 enter the first recesses 191 and 193 and are retained in the first recesses 191 and 193. At this time, the connecting mating portions 441 and 442 are blocked by the upper guide surfaces 136 and 137 of the first recesses 191 and 192, so that the fastener 100 is not easy to be separated from the first component, and the fastener 100 reaches the pre-installed position relative to the first component 301. In the pre-installed position, the connecting portion 130 of the fastener 100 exceeds the first side 411 of the first component 301.

[0060] During the process of connecting the fastener 100 connected to the first component 301 and the second component 302, there may be a situation where the connecting portion 130 of the fastener 100 is not aligned with the second opening 332 of the second component 302, and is blocked by the second component 302. At this time, if force is applied to the first component 301 or the second component 302 to make them approach, the fastener 100 will move relative to the first component 301. Figure 5BAs shown in FIG. 1 , when the connecting portion 130 is subjected to a downward external force as indicated by the arrow, the retaining arms 171 and 172 are squeezed by the connecting fitting portions 441 and 442 and deflected inwardly, so that the transition portions 166 and 167 of the connecting portion 130 can pass over the connecting fitting portions 441 and 442, so that the connecting fitting portions 441 and 442 can enter the second recesses 192 and 194. At this time, the fastener 100 has left the pre-installed position relative to the first component 301. Figure 5B In the position shown, the connecting portion 130 is flush with the first side 411 of the first component 301, which does not affect the first component 301 approaching the second component 302, but Figure 5B In the position shown in FIG. 1 , the fastener 100 is in an unstable position relative to the first component 301. When the external force is removed, the retaining arms 171 and 172 have a tendency to deflect outward, so that the fastener 100 can slide upward relative to the first component 301, so that the fastener 100 returns to the position shown in FIG. Figure 5A That is, after the connection portion 130 is aligned with the second opening 332, the fastener 100 can return to the position where the connection matching portions 441 and 442 enter the first recesses 191 and 193 of the retaining arms 171 and 172 under the elastic force of the retaining arms 171 and 172, and the connection portion 130 passes through the second opening 332. When the fastener 100 leaves the pre-installed position relative to the first component 301, the connection matching portions 441 and 442 may be aligned with any position of the main body sections 187 and 188, and the second recesses 192 and 194 are the farthest positions that the connection matching portions 441 and 442 can reach.

[0061] Fig. 6A is a three-dimensional diagram of a fastener installed in a first component and a second component, Figure 6B is a three-dimensional diagram of a fastener fastening and connecting a first component and a second component, Figure 6C yes Figure 6B Another perspective of the stereogram.

[0062] like Fig. 6A As shown, when the first component 301 and the second component 302 are connected, the fastener 100 is pre-installed in the first component 301. When the fastener 100 is pre-installed in the first component 301, the connection matching portions 441 and 442 enter the first recesses 191 and 193 of the retaining arms 171 and 172, so that the retaining arms 171 and 172 retain the fastener 100 in the first component 301. In the pre-installed position of the fastener 100, the connection portion 130 exceeds the first side 411 of the first component 301. At this time, the tops of the inclined surfaces 168 and 169 are higher than the first component 301. Then, a tool is used to apply force to the operating portion 180, so that the fastener 100 moves along the first component 301 as shown in FIG. Fig. 6A By rotating the fastener 100 in the clockwise direction as shown, the fastener 100 is Figure 6BIn the position shown, the first component 301 and the second component 302 are firmly connected.

[0063] like Figure 6B and Figure 6C As shown, the bottom of the inclined surfaces 168 and 169 of the connecting portion 130 abuts against the surface of the second component 302, and the first component 301 abuts against the first side 121 of the supporting plate 102, so that the first component 301 and the second component 302 are held between the inclined surfaces 168 and 169 and the supporting plate 102. Rotating the fastener 100 can change the contact point of the inclined surfaces 168 and 169, so that the first component 301 and the second component 302 have a suitable pressing force, and the first component 301 and the second component 302 are tightly connected. Figure 6B and Figure 6C In the position shown, the stopper 185 abuts against the length side 421 of the first opening 331, and the stopper 186 abuts against the length side 422 of the first opening 331, which can prevent the fastener 100 from excessively rotating. The stoppers 185 and 186 have a certain strength and can withstand a certain rotation force.

[0064] Figure 7 yes Figure 6B A cross-sectional view, as shown in Figure 6, when the fastener 100 rotates in the first component 301 and the second component 302, the sealing fitting portion 450 enters the receiving groove of the sealing portion 150 and squeezes the side wall 151 and the extension portion 152, so that the side wall 151 and the extension portion 152 are slightly deformed, so that the sealing fitting portion 450 contacts at least one of the first contact surface 208 and the second contact surface 209 and forms a seal, so that the fluid on both sides of the first component 301 and the second component 302 cannot be connected through the first opening 331 and the second opening 332.

[0065] In one embodiment of the present application, the first component is a vehicle door module, and the second component is a vehicle door sheet metal. The fastener 100 in the present application is an integrally formed part made of thermoplastic material, and its sealing part does not require secondary processing, and the manufacturing process is simple.

[0066] In the present application, the fastener 100 is first inserted into the opening of the component to be connected, and is rotated a certain angle to be installed in place. During the rotation process, a screwing tool is used to apply force to the operating part 180 so that the fastener 100 rotates with the tool. The tool applies a certain pressure to the operating part 180, and the operating part 180 needs to have a certain strength to avoid being damaged by the tool. In the present application, the fastener 100 is made of a thermoplastic material integrally molded. If the thickness of the operating part is too thick, it is easy to produce internal gaps during the processing process, affecting the strength of the operating part. In the present application, the operating part is provided with a plurality of grooves, which can improve this problem.

[0067] When the fastener 100 is rotated into place, the stoppers 185 and 186 can limit the further rotation of the fastener. The stoppers 185 and 186 have a certain thickness and are connected to the fixed portion of the retaining arm and the support plate, are not prone to deformation and damage, and can withstand large rotational torque.

[0068] In the present application, the retaining arms 171 and 172 of the fastener 100 have a fixed portion and a movable portion. The provision of the fixed portion enables the fastener to have a larger pull-out force relative to the first component, making it difficult to separate from the first component.
