Description

Technical Field

[0001] The present application relates to the field of automobile technology, and in particular to a zipper structure of a seat slide rail. Background Art

[0002] The seat rail is mainly composed of an upper rail and a lower rail, of which the upper rail is shorter and the lower rail is longer, and the upper rail can slide relatively along the extension direction of the lower rail. Since the upper rail cannot completely cover the lower rail, foreign objects can easily fall into the hollow area of ​​the lower rail from above, thereby affecting the sliding performance of the rail. In particular, foreign objects falling on the screw rod will shorten the service life of the rail, and there is also a risk of the rail being blocked, causing the rail to fail to operate normally.

[0003] In order to solve the problem of foreign objects entering the slide rail, the prior art designs a zipper structure on the slide rail to avoid the risk of foreign objects falling into the rail. The zipper structure is to install a zipper on the lower rail, and install a zipper head at each end of the upper rail. The zipper teeth between the two zipper heads are separated to provide space for accommodating the upper rail, and the zipper teeth in other areas are engaged to cover the upper rail to prevent foreign objects from entering the slide rail.

[0004] However, in this zipper structure, the zipper teeth are easily turned over, causing the waterproof film on the zipper surface to be scratched by the edge of the zipper head, thereby reducing the service life of the zipper waterproof film. Utility Model Content

[0005] The present application provides a zipper structure for a seat slide rail, which is used to solve the problem that a waterproof film on the surface of the zipper is easily scratched.

[0006] The present application provides a zipper structure of a seat slide rail, comprising a lower rail, an upper rail, two groups of elastic cloths and a zipper assembly, wherein the lower rail comprises: a first slide rail side wall and a second slide rail side wall arranged opposite to each other, a slide rail being formed between the first slide rail side wall and the second slide rail side wall; at least a portion of the upper rail is arranged in the slide rail and can slide along the extension direction of the slide rail; a zipper rack is arranged at one end of each of the two groups of elastic cloths, the other end of one group of elastic cloths in the two groups of elastic cloths is connected to the first slide rail side wall, and the other end of the other group of elastic cloths in the two groups of elastic cloths is connected to the second slide rail side wall; the zipper assembly is connected to the upper rail, and the zipper assembly comprises: a zipper head and a guide, wherein at least a portion of the zipper rack is located in the zipper head, so that when the zipper head slides, the two groups of zipper racks are engaged with or separated from each other; the guide is connected to the zipper head, and is used to guide the two groups of zipper racks into the zipper head.

[0007] The zipper structure of the seat slide rail in the present application includes a lower rail and an upper rail, wherein the lower rail includes a first slide rail side wall and a second slide rail side wall that are arranged opposite to each other, and a slide rail is formed between the first slide rail side wall and the second slide rail side wall; at least a portion of the upper rail is arranged in the slide rail and can slide along the extension direction of the slide rail. In this way, the upper rail can slide on the slide rail of the lower rail along the extension direction of the slide rail.

[0008] The zipper structure of the seat slide rail in the present application also includes two groups of elastic cloth and a zipper assembly, one end of the two groups of elastic cloth are provided with a zipper rack, the other end of one group of the two groups of elastic cloth is connected to the side wall of the first slide rail, and the other end of the other group of the two groups of elastic cloth is connected to the side wall of the second slide rail; the zipper assembly is connected to the upper rail, and the zipper assembly includes a zipper head, and at least part of the zipper rack is located in the zipper head, so that when the zipper head slides, the two groups of zipper racks are engaged or separated with each other.

[0009] In this way, when the upper rail slides, the zipper head of the zipper assembly can be driven to slide, and the two sets of zipper teeth are engaged or separated with each other, so that the elastic cloth covers or reveals the slide rail. In this way, when the zipper teeth are engaged, the elastic cloth covers the slide rail, thereby preventing foreign objects from entering the slide rail.

[0010] In addition, the zipper assembly also includes a guide member, which is connected to the zipper head and is used to guide the two sets of zipper racks into the zipper head. In this way, the guide member can guide the zipper racks before entering the zipper head to prevent the zipper racks from turning over when entering the zipper head, thereby preventing the waterproof film on the zipper surface from being scratched by the edge of the zipper head, thereby increasing the service life of the zipper waterproof film.

[0011] In some embodiments of the present application, the lower rail also includes a bottom wall, which is respectively connected to the first slide rail side wall and the second slide rail side wall; the zipper head also includes a rack channel, which is used to pass the zipper rack; a guide slide is provided on the guide member, which is used to pass the zipper rack so that the zipper rack located in the guide slide is flush with the rack channel.

[0012] In this way, when the zipper rack passes through the guide slide and the rack channel, since the guide slide is flush with the zipper rack in the rack channel, the zipper rack will not rotate when it is in the two positions (i.e., located at the guide slide and located at the rack channel), so the zipper rack will not flip over when entering the rack channel, thereby avoiding scratches on the waterproof film on the surface of the zipper and increasing the service life of the zipper waterproof film.

[0013] In some embodiments of the present application, the rack channel includes an upper wall surface away from the bottom wall, and the guide slide includes a first wall surface away from the bottom wall, and an end of the first wall surface close to the rack channel is flush with the upper wall surface.

[0015] In some embodiments of the present application, the rack channel further includes: a lower wall surface close to the bottom wall, and an end of the guide slope close to the rack channel is flush with the lower wall surface.

[0016] In some embodiments of the present application, the guiding slope is a curved surface.

[0017] In some embodiments of the present application, the zipper assembly also includes a connecting portion and a baffle. The connecting portion is arranged between the guide member and the zipper head and is connected to both the guide member and the zipper head. There is a gap between the connecting portion and the two sets of zipper racks; the baffle is connected to the guide member and is located below the gap.

[0018] In this way, the baffle located below the gap can prevent foreign matter from falling onto the screw rod through the gap, thereby preventing the normal operation of the slide rail from being affected.

[0019] In some embodiments of the present application, the zipper head is located above the baffle, and along the second direction, the baffle is gradually bent toward the side close to the bottom wall, wherein the second direction is the direction from the baffle to the side wall of the first slide rail; and or, the second direction is the direction from the baffle to the side wall of the second slide rail.

[0020] In some embodiments of the present application, the zipper structure also includes a first dustproof rubber cover and a second dustproof rubber cover, and one group of the two groups of elastic cloth is connected to the side wall of the first slide rail through the first dustproof rubber cover; the other group of the two groups of elastic cloth is connected to the side wall of the second slide rail through the second dustproof rubber cover.

[0021] The present application also provides a seat, which includes a seat body and a zipper structure of a seat slide rail in any of the above embodiments, wherein the seat body is connected to an upper rail.

[0022] In this way, when the upper rail slides, it can drive the seat body to slide on the slide rail along the extension direction of the slide rail, and at the same time drive the zipper head and the guide member to slide. In this way, the two sets of zipper racks engage or separate with each other as the zipper head slides, so that the elastic cloth covers or reveals the slide rail. Among them, the two sets of zipper racks that engage with each other extend the elastic cloth to cover the slide rail, thereby preventing foreign objects from entering the slide rail. During the sliding process of the zipper head and the guide member, the guide member guides the zipper racks to prevent the separated zipper racks from flipping when entering the zipper head, thereby preventing the waterproof film on the surface of the zipper from being scratched, thereby increasing the service life of the zipper waterproof film.

[0047] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0048] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0049] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0050] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances. In addition, when describing a pipeline, the "connected" and "connection" used in this application have the meaning of conduction. The specific meaning needs to be understood in conjunction with the context.

[0051] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0052] The seat rail is mainly composed of an upper rail and a lower rail, of which the upper rail is shorter and the lower rail is longer, and the upper rail can slide relatively along the extension direction of the lower rail. Since the upper rail cannot completely cover the lower rail, foreign objects can easily fall into the hollow area of ​​the lower rail from above, thereby affecting the sliding performance of the rail. In particular, foreign objects falling on the screw rod will shorten the service life of the rail, and there is also a risk of the rail being blocked, causing the rail to fail to operate normally.

[0053] In order to solve the problem of foreign objects entering the slide rail, the prior art designs a zipper structure on the slide rail to avoid the risk of foreign objects falling into the rail. The zipper structure is to install a zipper on the lower rail, and install a zipper head at each end of the upper rail. The zipper teeth between the two zipper heads are separated to provide space for accommodating the upper rail, and the zipper teeth in other areas are engaged to cover the upper rail to prevent foreign objects from entering the slide rail.

[0054] However, in this zipper structure, the zipper teeth are easily turned over, causing the waterproof film on the zipper surface to be scratched by the edge of the zipper head, thereby reducing the service life of the zipper waterproof film.

[0055] In a first aspect, the present application provides a zipper structure for a seat slide rail, which is used to solve the problem that a waterproof film on the surface of the zipper is easily scratched.

[0056] Figure 1 A zipper structure of a seat slide rail provided in an embodiment of the present application is shown. Figure 1 As shown, the zipper structure 100 includes a bottom rail 1 . Figure 2 The embodiment of the present application provides Figure 1 The local schematic diagram at A in the figure is as follows: Figure 2 As shown, the lower rail 1 includes a first slide rail side wall 11 and a second slide rail side wall 12 that are oppositely arranged, and a slide rail 13 is formed between the first slide rail side wall 11 and the second slide rail side wall 12 .

[0057] like Figure 1 As shown, the zipper structure 100 further includes an upper rail 2 . Figure 3 A schematic diagram of the structure of an upper rail, a lower rail and a screw rod provided in an embodiment of the present application is shown. Figure 2 and Figure 3 As shown, at least a portion of the upper rail 2 is disposed in the slide rail 13 and is capable of sliding along the extension direction of the slide rail 13 .

[0058] like Figure 3 As shown, a screw rod 14 is also provided in the lower rail 1, and the screw rod 14 is located in the slide rail 13, and the extension direction of the screw rod 14 is parallel to the extension direction of the slide rail 13. The upper rail 2 is slidably matched with the screw rod 14, so that the upper rail 2 slides along the extension direction of the screw rod 14, that is, the upper rail 2 slides in the extension direction of the slide rail 13.

[0059] Another example Figure 1 and Figure 2 As shown, the zipper structure 100 also includes two groups of elastic cloths 3, one end of each of the two groups of elastic cloths 3 is provided with a zipper rack 31, the other end of one group of the two groups of elastic cloths 3 is connected to the first slide rail side wall 11, and the other end of the other group of the two groups of elastic cloths 3 is connected to the second slide rail side wall 12.

[0060] Among them, Figure 2 As shown, the two groups of elastic cloth 3 may include: a first elastic cloth 3A and a second elastic cloth 3B, the first elastic cloth 3A is connected to the first slide rail side wall 11, the second elastic cloth 3B is connected to the second slide rail side wall 12, and the first elastic cloth 3A is located on the side of the second elastic cloth 3B away from the second slide rail side wall 12.

[0061] Similarly, the zipper rack 31 may include: a first zipper rack 311 and a second zipper rack 312, and the first zipper rack 311 and the second zipper rack 312 are both provided with a plurality of meshing teeth, and the arrangement direction of the plurality of meshing teeth on the first zipper rack 311 is parallel to the arrangement direction of the plurality of meshing teeth on the second zipper rack 312 and are arranged opposite to each other, so that the meshing teeth on the first zipper rack 311 can mesh with the meshing teeth on the second zipper rack 312.

[0062] In addition, the materials of the first elastic cloth 3A and the second elastic cloth 3B can be the same or different. The materials of the first elastic cloth 3A and the second elastic cloth 3B can be elastic materials such as polyester fiber or nylon, and the present application does not impose any limitation on this.

[0063] Figure 4 The structure diagram of the zipper assembly provided in the embodiment of the present application is shown as follows: Figure 4 As shown, the zipper structure 100 further includes a zipper assembly 4 , which is connected to the upper rail 2 . Figure 5 The embodiment of the present application provides Figure 4 The local schematic diagram at B is as follows: Figure 5 As shown, the zipper assembly 4 includes a zipper head 41 , and at least a portion of the zipper teeth 31 is located in the zipper head 41 , so that when the zipper head 41 slides, the two groups of zipper teeth 31 are engaged with or separated from each other.

[0064] So, like Figure 4 and Figure 5 As shown, when the upper rail 2 slides, the zipper head 41 of the zipper assembly 4 slides, and the two sets of zipper racks 31 are engaged or separated with each other, so that the two sets of elastic cloths 3 cover or reveal the slide rail 13. In this way, when the zipper racks 31 are engaged, the two sets of elastic cloths 3 cover the slide rail 13, thereby preventing foreign matter from entering the slide rail 13.

[0065] Optionally, the zipper assembly 4 is detachably fixedly connected to the upper rail 2. For example, the detachable fixed connection can be a threaded connection, a clamping connection, etc.

[0066] Optionally, the zipper assembly 4 is in a non-detachable fixed connection with the upper rail 2. For example, the non-detachable fixed connection can be riveting, welding, etc.

[0067] like Figure 5 As shown, the zipper assembly 4 further includes a guide member 42 , which is connected to the zipper head 41 and is used to guide the two groups of zipper racks 31 into the zipper head 41 .

[0068] Optionally, the connection between the guide member 42 and the zipper head 41 may be a detachable fixed connection, for example, Figure 5 As shown, the guide member 42 and the zipper head 41 can be fixedly connected by screws, so that the installation or removal of the guide member 42 is simple. Optionally, the connection between the guide member 42 and the zipper head 41 can also be a non-detachable fixed connection, which is not limited in the present application.

[0069] Optionally, the material of the guide member 42 can be plastic. In this way, the cost of the guide member 42 is low, and the plastic material has a certain elasticity and is not easy to cause damage to the zipper.

[0070] Optionally, the material of the guide member 42 may also be a metal material, so that the guide member 42 has good wear resistance and a long service life.

[0071] The zipper structure 100 of the seat slide in the present application includes two sets of elastic cloth 3 and a zipper assembly 4. One end of each of the two sets of elastic cloth 3 is provided with a zipper rack 31. The other end of one set of elastic cloth in the two sets of elastic cloth 3 is connected to the first slide side wall 11, and the other end of the other set of elastic cloth in the two sets of elastic cloth 3 is connected to the second slide side wall 12. The zipper assembly 4 is connected to the upper rail 2. The zipper assembly 4 includes a zipper head 41. At least part of the zipper rack 31 is located in the zipper head 41, so that when the zipper head 41 slides, the two sets of zipper racks 31 are engaged or separated with each other. In this way, when the upper rail 2 slides, the zipper head 41 of the zipper assembly 4 can be driven to slide, and the two sets of zipper racks 31 are engaged or separated with each other, so that the elastic cloth 3 covers or reveals the slide 13. In this way, when the zipper rack 31 is engaged, the elastic cloth 3 blocks the slide 13, thereby preventing foreign matter from entering the slide 13.

[0072] In addition, the zipper assembly 4 further includes a guide member 42, which is connected to the zipper head 41 and is used to guide the two sets of zipper racks 31 into the zipper head 41. In this way, the guide member 42 can guide the zipper racks 31 before entering the zipper head 41, thereby preventing the zipper racks 31 from turning over when entering the zipper head 41, thereby preventing the waterproof film on the zipper surface from being scratched by the edge of the zipper head 41, thereby improving the service life of the zipper waterproof film.

[0073] Figure 6 A schematic diagram of the structure of a guide member, a zipper head and a lower rail provided in an embodiment of the present application is shown. Figure 7 The embodiment of the present application provides Figure 6 The local schematic diagram at C in the figure is as follows: Figure 6 and Figure 7 As shown, the lower rail 1 further includes a bottom wall 15, and the bottom wall 15 is connected to the first slide rail side wall 11 and the second slide rail side wall 12 respectively.

[0074] Figure 8 One of the structural schematic diagrams of a guide member and a zipper head provided in an embodiment of the present application is shown. Fig. 9 The embodiment of the present application provides Figure 8 The right view of Figure 8 and Fig. 9 As shown, the zipper slider 41 further includes a rack channel 411 . Fig.10 FIG. 1 shows one of the structural schematic diagrams of a zipper rack and a zipper head provided in an embodiment of the present application, such as Fig. 9 and Fig.10 As shown, the rack channel 411 is used for the zipper rack 31 to pass through.

[0075] Among them, Figure 8 and Fig. 9As shown, the rack channel 411 may include: a first rack channel 411A and a second rack channel 411B, the first rack channel 411A and the second rack channel 411B are connected at a side away from the guide member 42, and the first rack channel 411A and the second rack channel 411B are provided with a rack outlet 411C at the end away from the guide member 42; a first rack inlet 411A1 is provided at the end of the first rack channel 411A close to the guide member 42, and a second rack inlet 411B1 is provided at the end of the second rack channel 411B close to the guide member. Fig. 9 and Fig.10 As shown, the first rack channel 411A is used for passing the first zipper rack 311 , and the second rack channel 411B is used for passing the second zipper rack 312 .

[0076] In this way, the first zipper rack 311 and the second zipper rack 312 can be engaged with or separated from each other through the rack channel 411 .

[0077] In a possible structural design, a zipper head 41 is connected to each end of the upper rail 2. The two zipper heads 41 may be a first zipper head and a second zipper head, which are arranged opposite to each other, wherein the specific structures of the first zipper head and the second zipper head can refer to the above description of the zipper head 41, and the present application will not repeat them here.

[0078] In this way, when the upper rail 2 slides toward the third direction in the extension direction of the slide rail 13, the third direction can be the direction from the first zipper head to the second zipper head, the second zipper head separates the first zipper rack 311 and the second zipper rack 312, and the first zipper head engages the first zipper rack 311 and the second zipper rack 312 to ensure that all zipper racks 31 passed by the upper rail 2 are engaged to prevent foreign objects from falling into the slide rail 13.

[0079] Similarly, when the upper rail 2 slides toward the fourth direction in the extension direction of the slide rail 13, the fourth direction can be the direction from the second zipper head to the first zipper head, the first zipper head separates the first zipper rack 311 and the second zipper rack 312, and the second zipper head engages the first zipper rack 311 and the second zipper rack 312 to ensure that all zipper racks 31 passed by the upper rail 2 are engaged to prevent foreign objects from falling into the slide rail 13.

[0080] In addition, if Figure 8 and Fig. 9 As shown, the guide member 42 is also provided with a guide slide 421. Figure 8 and Fig.10 As shown, the guide slide 421 is used for passing the zipper rack 31 so that the zipper rack 31 located in the guide slide 421 is flush with the rack channel 411 .

[0081] In some embodiments, the guide slide 421 is located at one end of the rack channel 411 close to the upper rail 2 .

[0082] In this way, the separated zipper racks 31 first pass through the guide slideway 421 and then enter the rack channel 411 . After passing through the rack channel 411 , the zipper racks 31 mesh with each other.

[0083] In this way, the zipper rack 31 smoothly enters the rack channel 411 in the zipper head 41 after passing through the guide slide 421 , thereby preventing the zipper rack 31 from flipping when entering the zipper head 41 , thereby preventing the waterproof film on the zipper surface from being scratched by the edge of the zipper head 41 .

[0084] Fig.11 FIG. 2 shows a second structural schematic diagram of a guide member and a zipper head provided in an embodiment of the present application. Figure 7 and Fig.11 As shown, the rack channel 411 includes an upper wall surface 4111 away from the bottom wall 15 , and the guide slide 421 includes a first wall surface 4211 away from the bottom wall 15 , and one end of the first wall surface 4211 close to the rack channel 411 is flush with the upper wall surface 4111 .

[0085] So, like Fig.10 and Fig.11 As shown, the upper surface of the zipper rack 31 in the guide slide 421 is flush with the upper surface of the zipper rack 31 in the rack channel 411, which can prevent the zipper rack 31 from flipping over and being scratched by the edge of the zipper head 41 when entering the rack channel 411.

[0086] Fig.12 FIG. 1 shows one of the structural schematic diagrams of a first wall and an upper wall provided in an embodiment of the present application, such as Fig.11 and Fig.12 As shown, in a possible structural design, one end of the first wall 4211 close to the rack channel 411 is flush with the upper wall 4111 , and the first wall 4211 is parallel to the upper wall 4111 .

[0087] In this way, after the zipper rack 31 enters the guide slide 421, it is limited by the first wall 4211, so that the zipper rack 31 located in the guide slide 421 is flush and parallel with the zipper rack 31 located in the rack channel 411, and the zipper rack 31 can smoothly enter the rack channel 411, thereby avoiding the zipper rack 31 from flipping over when entering the zipper head 41, thereby avoiding the waterproof film on the zipper surface from being scratched.

[0088] Fig.13 FIG. 2 shows a second structural schematic diagram of a first wall and an upper wall provided in an embodiment of the present application. Fig.11 and Fig.13As shown, in another possible mechanism design, one end of the first wall 4211 close to the rack channel 411 is flush with the upper wall 4111 , and the first wall 4211 is not parallel to the upper wall 4111 .

[0089] Exemplarily, the angle between the extended surface of the first wall 4211 and the extended surface of the upper wall 4111 may be in the range of 0-30°, which is not limited in the present application.

[0090] In other embodiments, the end of the first wall 4211 close to the rack channel 411 may not be flush with the upper wall 4111. The height difference between the first wall 4211 and the upper wall 4111 may be set according to the height of the zipper rack, which is not limited in the present application.

[0091] In some embodiments, the first wall surface 4211 is smoothly configured, so as to reduce the friction between the zipper rack 31 and the first wall surface 4211 when the zipper rack 31 passes through the first wall surface 4211 .

[0092] In some embodiments, Figure 8 and Fig.11 As shown, the end of the first wall 4211 away from the zipper head 41 is also provided with a first transition surface 42111 integrally formed therewith, the angle between the first transition surface 42111 and the first wall 4211 is less than 90°, the end of the first transition surface 42111 away from the first wall 4211 is higher than the end of the first transition surface 42111 close to the first wall 4211, and the connecting portion between the first transition surface 42111 and the first wall 4211 is smooth.

[0093] In this way, when the zipper rack 31 enters the guide slide 421, it first passes through the first transition surface 42111, is guided by the first transition surface 42111, and then passes through the first wall surface 4211, thereby reducing the friction between the zipper rack 31 and the edge of the first wall surface 4211 during the process of entering the guide slide 421, thereby improving the service life of the zipper rack 31.

[0094] In some embodiments, the guide member 42 has two groups of guide slides 421, and the two groups of guide slides 421 are divided into a first guide slide and a second guide slide. The first guide slide and the first rack channel 411A are located on the same side of the zipper head 41, and the second guide slide and the second rack channel 411B are located on the same side of the zipper head 41. In this way, the first zipper rack 311 can enter the first rack channel 411A through the first guide slide, and the second zipper rack 312 can enter the second rack channel 411B through the second guide slide.

[0095] The first wall surface 4211 in the guide slide 421 is also correspondingly set to two groups, and the two groups of first wall surfaces 4211 are divided into the first wall surface 4211 in the first guide slide and the first wall surface 4211 in the second guide slide. At the same time, the upper wall surface 4111 in the rack channel 411 is also correspondingly set to two groups, and the two groups of upper wall surfaces 4111 are divided into the upper wall surface 4111 in the first rack channel 411A and the upper wall surface 4111 in the second rack channel 411B.

[0096] Optionally, the first wall surface 4211 in the first guide slideway is symmetrically arranged with the first wall surface 4211 in the second guide slideway. Exemplarily, one end of the first wall surface 4211 in the first guide slideway close to the first rack channel 411A is flush with the upper wall surface 4111 in the first rack channel 411A, and one end of the first wall surface 4211 in the second guide slideway close to the second rack channel 411B is flush with the upper wall surface 4111 of the second rack channel 411B.

[0097] like Figure 7 and Figure 8 As shown, in some embodiments, the guide slide 421 also includes a guide slope 4212 close to the bottom wall 15 , and the guide slope 4212 extends along a first direction toward a side close to the bottom wall 15 ; the first direction is the direction from the guide member 42 to the zipper head 41 .

[0098] So, like Figure 8 and Fig.10 As shown, the guiding slope 4212 can make the zipper rack 31 enter the zipper head 41 more smoothly, thereby preventing the waterproof film on the zipper surface from being scratched by the edge of the zipper head 41 .

[0099] like Figure 7 and Figure 8 As shown, the rack channel 411 further includes a lower wall surface 4112 close to the bottom wall 15 , and one end of the guide slope 4212 close to the rack channel 411 is flush with the lower wall surface 4112 .

[0100] So, like Figure 8 and Fig.10 As shown, the lower surface of the zipper rack 31 in the guide slide 421 is flush with the lower surface of the zipper rack 31 in the rack channel 411, which can avoid the lower surface of the zipper rack 31 from scratching the zipper head 41 when the zipper rack 31 enters the rack channel 411.

[0101] In some embodiments, the guide slope 4212 is a curved surface. The curved surface gradually extends along the first direction toward the side close to the bottom wall 15, and the curved surface gradually extends from away from the first direction toward the side close to the bottom wall 15 along a direction perpendicular to the first direction. The first direction is the direction from the guide member to the zipper head.

[0102] Optionally, the curved surface may be convex toward the side away from the bottom wall 15. In this way, the curved surface can better support the zipper rack 31 and can make the zipper rack 31 enter the rack channel 411 more smoothly.

[0103] In some embodiments, the guide slope 4212 is a plane, which facilitates the production and manufacture of the guide slope 4212.

[0104] Fig.14 The following is a schematic diagram showing the changes of the waterproof membrane after the two zipper structures provided in the embodiments of the present application slide. Fig.14 The schematic diagrams of the structures of the waterproof film on the zipper surface of the zipper structure without the guide member 42 and the zipper structure with the guide member 42 after a certain number of cycles are shown in Figure 2. According to the durability test, for the zipper structure without the guide member 42, after 4000 cycles of sliding, the waterproof film on the zipper surface began to peel and break; for the zipper structure with the guide member 42, after 30000 cycles of sliding, the waterproof film on the zipper surface was still intact. Among them, one cycle means that the zipper structure completes the closing of a whole zipper rack 31 and the separation of a whole zipper rack 31. It can be seen that the zipper structure with the guide member 42 can effectively prevent the zipper waterproof film from being scratched and improve the service life of the zipper waterproof film.

[0105] In some embodiments, the guide slide 421 is divided into two groups, and the guide slopes 4212 in the guide slide 421 are also divided into two groups, and the two groups of guide slopes 4212 are respectively the guide slopes 4212 in the first guide slide and the guide slopes 4212 in the second guide slide. At the same time, the lower wall surface 4112 in the rack channel 411 is also divided into two groups, and the two groups of lower wall surfaces 4112 are divided into the lower wall surface 4112 in the first rack channel 411A and the lower wall surface 4112 in the second rack channel 411B.

[0106] Optionally, the guide slope 4212 in the first guide slide is symmetrically arranged with the guide slope 4212 in the second guide slide. Exemplarily, one end of the guide slope 4212 in the first guide slide close to the first rack channel 411A is flush with the lower wall 4112 in the first rack channel 411A, and one end of the guide slope 4212 in the second guide slide close to the second rack channel 411B is flush with the lower wall 4112 in the second rack channel 411B.

[0107] like Figure 5 As shown, the zipper assembly 4 further includes a connecting portion 43 , which is disposed between the guide member 42 and the zipper head 41 , and is connected to both the guide member 42 and the zipper head 41 .

[0108] In some embodiments, Figure 5As shown, the zipper head 41 and the connecting portion 43 are an integral structure. The zipper head 41 and the connecting portion 43 are integrally formed by an integral molding process. For example, the integral molding process can be die casting, sand casting, investment casting, etc.

[0109] Fig.15 The second structural schematic diagram of a zipper rack and a zipper head provided in an embodiment of the present application is shown. Fig.16 The embodiment of the present application provides Fig.15 The local schematic diagram at D in the figure is as follows: Fig.15 and Fig.16 As shown, there are gaps 45 between the connecting portion 43 and the two groups of zipper racks 31 .

[0110] It is understandable that some foreign matter can easily pass through the gap 45 and fall onto the screw rod 14 , thus affecting the normal operation of the slide rail 13 .

[0111] Fig.17 A schematic diagram of the structure of a baffle and a gap provided in an embodiment of the present application is shown. Figure 7 and Fig.17 As shown, the zipper assembly 4 further includes a baffle 44 , which is connected to the guide member 42 .

[0112] The baffle 44 and the guide member 42 are integrally formed by an integral molding process, such as die casting, sand casting, investment casting, and the like.

[0113] like Fig.16 and Fig.17 As shown, the baffle 44 is located below the gap 45 .

[0114] In this way, some foreign matter can fall onto the baffle 44 through the gap 45 , thereby preventing it from falling onto the screw rod 14 , thereby preventing the normal operation of the slide rail 13 from being affected.

[0115] like Figure 7 and Fig.17 As shown, the zipper head 41 is located above the baffle 44, and along the second direction, the baffle 44 is gradually bent toward the side close to the bottom wall 15, and the second direction is the direction from the baffle 44 to the first slide rail side wall 11; and or, the second direction is the direction from the baffle 44 to the second slide rail side wall 12.

[0116] In this way, some foreign matter (for example, sand) falls onto the baffle plate 44 through the gap 45, and slides from the baffle plate 44 to the side close to the bottom wall 15, and finally falls onto the slide rail 13 from the side of the baffle plate 44 close to the first slide rail side wall 11, and / or the side close to the second slide rail side wall 12, thereby preventing these foreign matter from falling directly onto the screw rod 14 and causing blockage, thereby preventing the normal operation of the slide rail 13 from being affected.

[0117] In some embodiments, Figure 1 and Figure 2 As shown, the zipper structure 100 further includes two groups of dustproof rubber covers 5, which are a first dustproof rubber cover 51 and a second dustproof rubber cover 52. One group of the two groups of elastic fabrics 3 is connected to the first slide rail side wall 11 through the first dustproof rubber cover 51; the other group of the two groups of elastic fabrics 3 is connected to the second slide rail side wall 12 through the second dustproof rubber cover 52. The first dustproof rubber cover 51 and the second dustproof rubber cover 52 cooperate with each other to shield the lower rail 1 and prevent external foreign matter from entering the lower rail 1.

[0118] Exemplarily, the connection between the two sets of dustproof rubber covers 5 and the lower rail 1 is a detachable fixed connection, such as a snap connection, a screw connection, etc. This makes it easy to disassemble or install the dustproof rubber covers 5.

[0119] Exemplarily, the connection between the two sets of dustproof rubber covers 5 and the lower rail 1 is a non-detachable fixed connection, such as riveting, gluing, etc.

[0120] In some embodiments, the two sets of elastic cloth 3 are located between the two sets of dustproof rubber covers 5 and the lower rail 1, and the two sets of elastic cloth 3 can also be connected to the two sets of dustproof rubber covers 5. In this way, the two sets of elastic cloth 3 are indirectly connected to the lower rail 1, which is convenient for fixing or replacing the elastic cloth 3.

[0121] like Figure 2 As shown, in some embodiments, a mounting groove 53 is provided on the dustproof rubber cover 5, and the shape of the mounting groove 53 on the cross section perpendicular to the extension direction of the mounting groove 53 is an inverted trapezoid, and a mounting portion 32 is sewn on one side of the elastic cloth 3 connected to the dustproof rubber cover, and the mounting portion 32 is in a mother-and-child fit with the mounting groove 53.

[0122] In this way, the elastic cloth 3 and the dustproof rubber cover 5 can be connected through the installation groove 53, so that the elastic cloth 3 can be easily replaced, installed or removed.

[0123] Fig.18 , Fig.19 , Fig. 20 , Fig.21 , Fig. 22 and Fig.23 Schematic diagrams of the structure of the dustproof rubber cover and the elastic cloth provided in the embodiments of the present application are shown. Fig.18 , Fig.19 , Fig. 20 , Fig.21 , Fig. 22 and Fig.23 As shown, the shape of the mounting groove 53 in the cross section perpendicular to the extension direction of the mounting groove 53 can also be arrow-shaped, heart-shaped, elliptical, rectangular, triangular and circular, and the shape of the mounting portion 32 in the cross section perpendicular to the extension direction of the mounting groove 53 matches the shape of the mounting groove 53.

[0124] In some embodiments, the connection between the two sets of elastic fabrics 3 and the two sets of dustproof rubber covers 5 can also be bonded and fixed, and the bonding method can be strong glue or secondary injection molding.

[0125] In a second aspect, the present application further provides a seat, comprising: a seat body and a zipper structure 100 of a seat slide rail as described in the first aspect above, wherein the seat body is connected to an upper rail 2 .

[0126] In this way, when the upper rail 2 slides, it can drive the seat body to slide on the slide rail 13 along the extension direction of the slide rail 13, and at the same time drive the zipper head 41 and the guide member 42 to slide. In this way, the two sets of zipper racks 31 are meshed or separated with the sliding of the zipper head 41, so that the elastic cloth 3 covers or reveals the slide rail 13. Among them, the two sets of zipper racks 31 meshed with each other extend the elastic cloth 3 to cover the slide rail 13, thereby preventing foreign objects from entering the slide rail 13. In the process of sliding the zipper head 41 and the guide member 42, the guide member 42 guides the zipper rack 31 to prevent the zipper rack 31 from turning over before entering the zipper head 41, thereby preventing the waterproof film on the zipper surface from being scratched, thereby improving the service life of the zipper waterproof film.

[0127] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
