[0028] Figure 1A is a three-dimensional diagram of the fastener in this application, Figure 1B yes Figure 1A Exploded view of the fasteners. Figure 1A and Figure 1B As shown, the fastener 100 is used to connect the first component and the second component. The fastener 100 includes a clamp seat 101 and a clip 102. The clip 102 is installed in the clamp seat 101, and when subjected to a certain external force, the clip 102 can be separated from the clamp seat 101. That is to say, the clip 102 is detachably connected to the clamp seat 101, and multiple plugging and unplugging can be achieved between the two. The clamp seat 101 is made of plastic material and has a certain strength. The clip 102 is made by stamping of metal sheets. The clip 102 and the clamp seat 101 are retained in the clamp seat 101 by interference fit. The clamp seat 101 can be connected to the first component, and the clip 102 can be connected to the second component, so that the fastener 100 can connect the first component and the second component. The fastener 100 has a length direction L, a height direction H and a width direction W. In the present application, the length direction L is the first direction, the width direction W is the second direction, and the first direction is approximately perpendicular to the second direction.
[0029] Figure 2A yes Figure 1B A three-dimensional view of the middle clamp seat. Figure 2B yes Figure 2A Side view of the middle clamp. Figure 2A and Figure 2B As shown, the clamp seat 101 includes a head 211, a support portion 212, and a pair of side walls 215 and 216. The support portion 212 is generally in the shape of a plate and has a first side 221 and a second side 222. The first side 221 of the support portion 212 is connected to the head 211. The side walls 215 and 216 are respectively connected to both ends of the support portion 212 in the width direction and extend in a direction away from the head 211. The side walls 215 and 216 and the support portion 212 and the second side 222 are surrounded by three sides with an open accommodation space 250, and the accommodation space 250 is used to accommodate the clamp 102. The opening formed between the far ends of the side walls 215 and 216 is an insertion port 290, and the clamp 102 can enter the accommodation space 250 from the insertion port 290 along the height direction H of the fastener 100.
[0030] The side wall 215 has a window 255 that penetrates the inside and outside thereof along the width direction W of the fastener 100. The window 255 is substantially square and is located in the middle of the side wall 215. The side wall 216 has a window 256 that penetrates the inside and outside thereof along the width direction W of the fastener 100. The window 256 is substantially square and is located in the middle of the side wall 215. In the length direction L of the fastener 100, the windows 255 and 256 have certain lengths L1 and L2, respectively. The windows 255 and 256 form receiving portions that can receive corresponding portions of the clip 102. The windows 255 and 256 have lower edges 291 and 292, respectively.
[0031] The clamp seat 101 has a clamp seat guide portion 280 at one end near the insertion opening 290, and the inner sides of the side walls 215 and 216 extend obliquely toward each other from the insertion opening 290 along the height direction of the fastener 100 at the clamp seat guide portion 280. Viewed along the length direction of the fastener 100, the clamp seat guide portion 280 is a trumpet shape that gradually narrows from the insertion opening 290 to the head 211.
[0032] The head 211 includes an upper section 241 and a lower section 242, and the upper section 241 is connected to the support portion 212 through the lower section 242. In one embodiment of the present application, the outer diameter of the upper section 241 is slightly larger than the outer diameter of the lower section 242, and the upper section 241 includes a pair of grooves 267 and 268 formed by inward depression from opposite sides of the upper section 241 in the circumferential direction, and the grooves 267 and 268 are used to cooperate with corresponding parts of the first component, so that the first component can be inserted into the grooves 267 and 268. The upper section 241 has a hook portion 277 extending from the outer side of the upper section 241, and the distal end of the hook portion 277 has a protrusion 279, which can enter the corresponding recess of the first component to prevent the clamp seat 101 from falling off the first component. The grooves 267 and 268 extend along the width direction W of the fastener.
[0033] In another embodiment of the present application, the grooves 267 and 268 are formed by the upper section 241, the lower section 242 and the support portion 212. In yet another embodiment of the present application, the head 211 includes only the upper section 241.
[0034] Figure 3A yes Figure 1B The stereogram of the middle clip, Figure 3B yes Figure 3A Side view of the middle clip. Figure 3A and Figure 3BAs shown, the clip 102 includes a top 311, a pair of side portions 312 and 313, a pair of retaining portions 321 and 322, and two pairs of elastic arms 323 and 324, 325 and 326. The side portions 312 and 313 extend away from each other from both sides of the top 311. A clamping space 350 is formed between the side portions 312 and 313, and a corresponding portion of the second component can enter the clamping space 350.
[0035] The clamp 102 is symmetrically shaped when viewed along the length direction of the fastener. The top 311 is roughly in the shape of an arched arc, and its two ends are connected to the side parts 312 and 313 respectively. The side part 312 includes a main body 341 and a bending part 342, and the two ends of the main body 341 are connected to the top 311 and the bending part 342 respectively. The side part 313 includes a main body 343 and a bending part 344, and the two ends of the main body 343 are connected to the top 311 and the bending part 344 respectively. The angle between the main bodies 341 and 343 is smaller than the angle between the bending parts 342 and 344. The bending parts 342 and 344 form a clamp guide part 390, and the inner side of the clamp guide part 390 forms a trumpet-shaped opening. The clamp guide part 390 is used to guide the second component into the clamping space 350. The main bodies 341 and 343 have hollow parts 371 and 372 running through the inner and outer sides thereof, respectively.
[0036] The elastic arms 323 and 324 extend from one end of the bent portions 342 and 344 close to the corresponding main body toward the top 311 and toward each other, respectively. Similarly, the elastic arms 325 and 326 extend from one end of the bent portions 342 and 344 close to the corresponding main body toward the top 311 and toward each other. The distal ends of the elastic arms 323 and 324 overlap in the width direction of the fastener 100, and the distal ends of the elastic arms 325 and 326 overlap in the width direction of the fastener 100. In one embodiment of the present application, the extension direction of the elastic arms 323 and 325 is the same as the extension direction of the bent portion 342, and the extension direction of the elastic arms 324 and 326 is the same as the extension direction of the bent portion 344. In the length direction of the fastener 100, the elastic arms 323 and 325 are close to both sides of the hollow portion 371, and the elastic arms 324 and 326 are close to both sides of the hollow portion 372.
[0037] The two ends of the retaining portion 321 are connected to the top 311 and the bent portion 342, and protrude in a direction away from the side portion 313, thereby protruding from the outer surface of the main body 341 to form a first protrusion 381. In the length direction of the fastener, the retaining portion 321 is located between the elastic arms 323 and 325. The two ends of the retaining portion 322 are connected to the top 311 and the bent portion 344, and protrude in a direction away from the side portion 312, thereby protruding from the outer surface of the main body 343 to form a second protrusion 382. In the length direction of the fastener, the retaining portion 322 is located between the elastic arms 324 and 326. The first protrusion 381 and the second protrusion 382 have contact surfaces 385 and 386, respectively, and the contact surfaces 385 and 386 extend away from each other in a direction toward the top 311. The contact surfaces 385 and 386 cooperate with the windows 255 and 256 of the clamp seat 101, respectively, to retain the clamp 102 in the clamp seat 102. In the length direction of the fastener, the lengths of the retaining portions 321 and 322 are shorter than the lengths of the windows 255 and 256 , respectively.
[0038] Figure 4 yes Figure 1A A cross-sectional view of a fastener in FIG. Figure 4 As shown, when the clip 102 is located in the clip seat 101, the top 311 of the clip 102 is close to the second side of the support portion 212, and the support portion 212 can prevent the clip 102 from moving toward the head 211 along the height direction. The first protrusion 381 and the second protrusion 382 enter the windows 255 and 256 respectively, and the first contact surfaces 385 and 386 abut against the lower edge 291 of the window 255 and the lower edge 292 of the window 256 respectively, thereby limiting the movement of the clip 102 away from the head 211 along the height direction. The bent portions 342 and 344 of the clip 102 abut against the side walls 215 and 216 of the clip seat 101, and the clip 102 is in a compressed state, and the bent portions 342 and 344 of the clip 102 apply a certain elastic force to the side walls 215 and 216 respectively to connect the clip 102 to the clip seat 101, so that the clip 102 cannot shake or slide relative to the clip seat 101 along the length direction. As shown in FIG. Figure 4 As shown, when the clip 102 is installed in place in the clip seat 101 , the clip 102 and the clip seat 101 are not easily moved relative to each other, and the clip 102 and the clip seat 101 together form the fastener 100 .
[0039] The clip guide portion 390 and the clip seat guide portion 280 match in shape and together form a trumpet-shaped fastener guide portion 490 to guide the corresponding portion of the second component into the fastener.
[0040] Figure 5A is a schematic diagram of the clamp being in the first position relative to the clamp seat, Figure 5B It is a schematic diagram when the clamp is in the second position relative to the clamp seat.
[0041] like Figure 5A and Figure 5B As shown, the dotted box indicates the relative position of the clip 102. Since the lengths of the retaining portions 321 and 322 are respectively smaller than the lengths of the windows 255 and 256, the clip 102 can have multiple installation positions relative to the clip seat 101. Figure 5A As shown, when the clip 102 is in the first installation position relative to the clip seat 101, the clip 102 is in a position close to the left relative to the clip seat. At this time, the left edge of the retaining portion 321 is close to the left edge of the window 255, and there is a gap between the right edge of the retaining portion 321 and the right edge of the window 255. Figure 5B As shown, when the clip 102 is in the second installation position relative to the clip base 101, the clip 102 is in a position close to the right side relative to the clip base. At this time, the right edge of the retaining portion 321 is close to the right edge of the window 255, and there is a gap between the left edge of the retaining portion 321 and the left edge of the window 255. Figure 5A and Figure 5B Two installation positions of the clip 102 relative to the clamp seat 101 are shown respectively. Along the length direction L of the fastener, the clip 102 can be installed at any position between the first position and the second position relative to the clamp seat 101. After the clamp seat 102 of the present application is separated from the clip 102, when the clip 102 is installed in the clamp seat 101 again, a certain position can be changed in the length direction of the fastener to meet the needs of repeated installation.
[0042] Fig. 6A yes Figure 1A FIG. 1 is an exploded view of a fastener and a first component and a second component. Figure 6B yes Figure 1A A three-dimensional diagram of the fastener in the embodiment and the first component and the second component when connected. Figure 6C yes Figure 1A A three-dimensional view of the clamp seat and the second part of the fastener when separated from the clamp.
[0043] like Fig. 6A and Figure 6B As shown, the first component 601 has a pair of convex ribs 611 and 612, which can enter the pair of grooves 267 and 268 of the clamp seat 101 and can move along the width direction of the fastener relative to the clamp seat 101. The second component 602 has a generally plate-shaped mounting portion 613, which has a certain thickness and can enter the insertion port 290 of the fastener 100.
[0044] When connecting the first component 601 with the second component 602, first insert the ribs 611 and 612 of the first component 601 into the grooves 267 and 268 of the clamp seat 101, so that the first component 601 is connected to the fastener 100, and then the fastener 100 connected to the first component 601 is pushed toward the second component 602 along the height direction, so that the mounting portion 613 enters the clamping space 350, so that the mounting portion 613 is between the elastic arms 323, 325 and the elastic arms 324 and 326, and cannot move relative to the fastener, and the fastener is connected to the second component 602.
[0045] Figure 6B The connection state of the first component 601 and the second component 602 is shown. When the fastener 100 is connected to the second component, due to the limited operation field of view, the clamping space 350 may not be directly aligned with the mounting portion 613 of the first component, and the shape of the fastener guide portion 490 is easy to guide the mounting portion 613 into the insertion port 290, and thus into the clamping space 350.
[0046] In one application of the present application, the first component 601 is an interior panel of a vehicle, and the second component 602 is an aluminum alloy sheet of the vehicle. Sometimes, the first component 601 and the second component 602 need to be separated and then reconnected. Figure 6C As shown, when the first component 601 is separated from the second component 602, an external force is applied to the first component 601 away from the second component 602, and the second component 602 and the clamp seat 101 and the clip 102 are separated. The clip 102 is retained on the second component 602. When the first component 601 and the second component 602 are connected again, the clamp seat 101 is moved toward the clip 102 so that the clamp seat 101 and the clip 102 are connected again. In the process of reconnecting the clamp seat 101 and the clip 102 for the second time, it may be that the clamp seat 101 and the clip 102 cannot reach the initial installation position due to position offset. In the present application, the fastener 100 can adapt to the offset of a certain distance between the clamp seat 101 and the clip 102 in the length direction, so that the reconnection of the first component 601 and the second component 602 is easy to operate.
