Description

Technical Field

[0001] This application belongs to the technical field of vehicle curtains, and particularly relates to a retrofit type vehicle curtain guide rail structure. Background Art

[0002] With the booming development of the logistics and transportation industry, the demand for trucks has been increasing year by year. At the same time, with the continuous improvement of living standards, people's requirements for "home on wheels" are also getting higher and higher. Therefore, vehicle curtains have emerged, which can effectively improve the comfort of users' rest in the vehicle and enhance the privacy during the rest process.

[0003] Currently, truck curtain guide rails are divided into two types. One is the original curtain guide rail provided by vehicle manufacturers, which has the advantages of strong specificity, good integrity, and stable structure. However, this type of curtain guide rail is designed and developed synchronously with the whole vehicle. It uses aluminum profile bending and forming processes, has extremely high requirements for supporting mating parts, requires the synchronous design and layout of the curtain guide rail structure during the whole vehicle development, and also needs to reserve curtain guide rail installation points on the white body. This leads to extremely high requirements for development synchronization and relatively high development costs. The other is the aftermarket retrofit curtain guide rail, which has the advantage of strong versatility. However, it mostly uses PP extruded guide rails and is fixed to the vehicle interior with exposed screws. After installation, the guide rail is not coordinated with the overall shape of the vehicle, and there are also problems such as poor stability and durability. Summary of the Utility Model

[0004] This application provides a retrofit type vehicle curtain guide rail structure to solve at least one of the above technical problems.

[0005] The technical solution adopted in this application is as follows:

[0006] A retrofit type vehicle curtain guide rail structure includes a guide rail body and a mounting seat. The mounting seat includes a clamping portion and a connecting portion. The clamping portion is in clamping fit with the guide rail body. A receiving opening is provided in the lining of the vehicle ceiling, and the connecting portion is in clamping fit with the lining through the receiving opening.

[0007] By adopting the above technical solution, when retrofitting a curtain on a vehicle, first install the mounting seat on the lining of the vehicle ceiling so that the connecting portion is in clamping fit with the lining through the receiving opening, and then the lining supports the mounting seat. Then, assemble the guide rail body to the mounting seat so that the guide rail body is in clamping fit with the clamping portion. Finally, install the curtain on the guide rail body to complete the retrofit of the curtain on the vehicle.

[0008] Since the curtain rail structure in this application is assembled on the inner lining of the vehicle roof, compared with the original curtain in the prior art, the development cost of the curtain rail is reduced, the requirement for vehicle development synchronization is reduced, and at the same time, the situation of reserving installation positions on the white body is avoided, thus greatly reducing the cost of installing curtains on the vehicle; in addition, compared with the solution of installing a curtain rail in the aftermarket, the situation of needing to use screws to fix it is avoided, increasing the coordination between the curtain rail structure and the overall shape of the vehicle, and at the same time increasing the stability and durability of the curtain rail structure.

[0009] Optionally, the connecting portion includes a first connecting section, a second connecting section, and a third connecting section located between the first connecting section and the second connecting section. The first connecting section and the second connecting section form a receiving space for receiving the inner lining on opposite sides of the third connecting section, and the clamping portion is connected to the second connecting section.

[0010] By adopting the above technical solution, when installing the mounting seat, first align the first connecting section with the receiving opening, then extend the first connecting section through the receiving opening to the outside of the inner lining, and then rotate the mounting seat by 90 degrees, so that the first connecting section abuts against the outside of the inner lining, the third connecting section is located in the receiving opening, and the second connecting section is located inside the inner lining, that is, a part of the inner lining is located in the receiving space, and then the connecting portion is clamped and matched with the inner lining to complete the installation of the mounting seat. In this process, only the mounting seat needs to be pushed and rotated, thus greatly reducing the installation difficulty of the mounting seat, improving the assembly efficiency of the mounting seat, and greatly reducing the difficulty of installing curtains on the vehicle; at the same time, after the guide rail body is clamped to the clamping portion, the guide rail can also limit the mounting seat to avoid the situation that the connecting portion is in contact with the inner lining and falls off due to the vibration of the vehicle, thus greatly ensuring the installation stability of the curtain rail structure.

[0011] Optionally, the length L1 of the first connecting section and the length L2 of the second connecting section satisfy: L1 > L2.

[0012] By adopting the above technical solution, since the length of the first connecting section is greater than the length of the second connecting section, the stop matching area between the first connecting section and the inner lining is increased, and the situation that the first connecting section breaks away from the outside of the inner lining through the receiving opening is greatly avoided, thereby increasing the clamping and matching stability between the connecting portion and the inner lining, increasing the connection stability between the mounting seat and the inner lining, and thus increasing the connection stability between the curtain rail structure and the inner lining.

[0013] Optionally, the width D1 of the first connecting section, the width D2 of the second connecting section, the length L1 of the first connecting section, and the length L2 of the second connecting section satisfy: D1 < L2 < L1 < D2.

[0014] By adopting the above technical solution, since the width of the second connecting section is greater than the length of the first connecting section, after the connecting part is clamped and matched with the inner lining, the second connecting section can block the accommodating opening, so as to increase the aesthetics of the vehicle interior, thereby improving the user experience. At the same time, the width of the second connecting section is greater than the width of the first connecting section, avoiding the situation that when the first connecting section extends to the outside of the inner lining through the accommodating opening, the second connecting section can extend to the outside of the inner lining through the accommodating opening, thus greatly reducing the assembly difficulty of the mounting seat and greatly improving the assembly efficiency of the mounting seat.

[0015] Optionally, the length L3 of the third connecting section and the thickness D of the inner lining satisfy: D > L3 ≥ 0.9D.

[0016] By adopting the above technical solution, since the length of the third connecting section is less than the thickness of the inner lining, the distance between the first connecting section and the second connecting section is less than the thickness of the inner lining. Thus, after the connecting part is clamped and matched with the inner lining, the connecting part is in interference fit with the inner lining to further increase the clamping stability between the connecting part and the inner lining. At the same time, it avoids the noise generated by the relative shaking between the clamping part and the inner lining during the driving of the vehicle, so as to ensure the driving quality of the vehicle and further ensure the user experience.

[0017] Optionally, guiding surfaces are provided on both sides of the first connecting section facing the second connecting section, so that the thicknesses of both sides of the second connecting section gradually decrease in the direction away from the third connecting section.

[0018] By adopting the above technical solution, since guiding surfaces are provided on both sides of the first connecting section facing the second connecting section, the opening size of the accommodating space is increased. Thus, when the mounting seat is rotated to make the connecting part clamped and matched with the inner lining, the guiding surfaces can guide the inner lining and the first connecting section, so as to greatly reduce the difficulty of clamping and matching the connecting part with the inner lining. At the same time, it reduces the force required to rotate the mounting seat, so as to greatly improve the installation efficiency of the mounting seat, and avoids the situation that the inner lining may be damaged when the mounting seat is rotated, so as to ensure the structural strength of the inner lining, and further ensure the supporting stability of the inner lining for the curtain rail structure, so as to greatly improve the stability of the curtain rail structure.

[0019] Optionally, the peripheral surface of the third connecting section has a guiding curved surface.

[0020] By adopting the above technical solution, since the circumferential surface of the third connecting section has a guiding curved surface, the situation where the third connecting section interferes with the wall of the accommodating port during the rotation of the mounting seat is avoided, thereby increasing the smoothness when rotating the mounting seat, and at the same time reducing the force required for rotating the mounting seat, so as to greatly improve the assembly efficiency of the mounting seat and achieve the effect of facilitating the assembly of the mounting seat. In addition, it can make the third connecting section abut against two opposite walls of the accommodating port to prevent a gap between the third connecting section and two opposite walls of the accommodating port, which may cause the mounting seat to move relative to the inner lining, further reducing the noise generated during vehicle driving and increasing the installation stability of the curtain rail structure.

[0021] Optionally, clamping grooves are oppositely arranged on both sides of the guide rail body. The clamping part includes a supporting section arranged on the connecting section and clamping sections arranged on opposite sides of the supporting section. A clamping space for accommodating the guide rail body is formed between the two clamping sections, and the two clamping sections are respectively clamped in the two clamping grooves.

[0022] By adopting the above technical solution, when installing the guide rail body, first align the guide rail body with the opening of the clamping space, and then push the guide rail body upward, so that the top of the guide rail body enters the clamping space, and the two clamping sections are respectively clamped in the two clamping grooves to complete the installation of the guide rail body. In this process, only pushing the guide rail body upward is needed, thus greatly improving the installation efficiency of the guide rail body.

[0023] Optionally, the wall bodies on both sides of the top of the guide rail body are recessed towards the inside of the guide rail body to form an avoidance space, and the wall bodies on the top of the guide rail body extend towards both sides to form blocking wall bodies. The blocking wall bodies and the avoidance space together form the clamping groove. The distance K between the opposite ends of the two blocking wall bodies and the width W of the guide rail body satisfy: K < W.

[0024] By adopting the above technical solution, since the distance between the opposite ends of the two blocking wall bodies is less than the width of the guide rail body, the width of the top of the guide rail body is reduced. Then, when assembling the guide rail body to the clamping part, the blocking wall bodies can guide the guide rail body, so that the guide rail body can more easily enter the clamping space and be clamped and matched with the clamping section, greatly reducing the installation difficulty of the guide rail body and further improving the installation efficiency of the guide rail body.

[0025] Optionally, the clamping section includes a limiting wall body connected to the supporting section and an elastic wall body arranged on the limiting wall body. The elastic wall body is clamped in the clamping groove.

[0026] By adopting the above technical solution, when assembling the guide rail body, first align the guide rail body with the opening of the clamping space, and then push the guide rail body upward so that the guide rail body abuts against the elastic wall body. Continue to push the guide rail body, so that the elastic wall body undergoes elastic deformation, and the top end of the guide rail body enters the clamping space. Then the elastic wall body resumes deformation and extends into the clamping groove to be clamped and matched with the groove wall of the clamping groove to complete the installation of the guide rail body. Due to the existence of the elastic wall body, the force required for assembling the guide rail body is reduced, thereby greatly improving the installation efficiency of the guide rail body.

[0027] Optionally, the clamping portion is provided with an elastic limiting portion, and the elastic limiting portion can abut against the guide rail body to apply an elastic force to the guide rail body in a direction away from the connecting portion. [[ID=__5]]

[0028] By adopting the above technical solution, after the guide rail body is installed on the clamping portion, the elastic limiting portion abuts against the guide rail body and applies a force to the guide rail body in a direction away from the connecting portion, thereby making the guide rail body and the clamping portion tightly clamped, so as to avoid the situation that the guide rail body and the clamping portion can relatively shake in the vertical direction, which causes the guide rail body to be not firmly fixed. Furthermore, the fixing stability of the guide rail body is greatly increased, and at the same time, the stability of the mounting seat can also be increased, avoiding the situation that noise is generated due to the relative movement between the mounting seat and the guide rail.

[0029] Optionally, the elastic limiting portion is an elastic sheet provided at both ends of the clamping portion, and the elastic sheet extends obliquely in a direction approaching the guide rail body along a direction away from the clamping portion.

[0030] By adopting the above technical solution, since the elastic limiting portion is an elastic sheet provided at both ends of the clamping portion, on the one hand, the structure of the elastic limiting portion is simplified to reduce the production difficulty and production cost of the mounting seat, and at the same time, the elastic contact points between the clamping portion and the guide rail body are increased to further increase the connection stability between the guide rail body and the clamping portion.

[0031] Optionally, an included angle is provided between the connecting portion and the clamping portion, so that the opening of the guide rail body faces downward.

[0032] By adopting the above technical solution, since the position where the vehicle needs to install the curtain is usually on the side of the interior space of the vehicle, and the inner lining on the side is usually bent, then setting the connecting portion and the clamping portion to be at an included angle can make the installation direction of the guide rail body vertically upward and the opening of the guide rail body downward, so as to ensure the smoothness when pulling the curtain, thereby improving the user experience.

[0033] Optionally, a plurality of mounting seats are arranged at intervals along the length direction of the guide rail body.

[0034] By adopting the above technical solution, since a plurality of mounting seats are arranged at intervals along the length direction of the guide rail body, the number of fixed points for the guide rail body is increased, thereby enhancing the stability of the guide rail body, further increasing the stability of the curtain guide rail structure, and at the same time enabling the structure of the mounting seat to be as small as possible to ensure the structural strength of the inner lining and enhance the connection stability between the mounting seat and the inner lining.

[0035] Optionally, a plurality of sliders for hanging curtains are slidably connected in the guide rail body, and magnets are arranged on both sides of each slider; or, magnets are arranged on one side of each slider, and iron sheets are arranged on the other side of each slider, so that two adjacent sliders can be magnetically connected.

[0036] By adopting the above technical solution, since magnets are arranged on both sides of each slider; or, magnets are arranged on one side of each slider and iron sheets are arranged on the other side of each slider, after the curtain is pulled to the storage position, two adjacent sliders can be magnetically attracted together, so as to enhance the stability of the curtain moving to the storage position, avoid the situation that the slider moves along the guide rail body during the vehicle driving process and affects the driver's line of sight, and further improve the driving safety of the vehicle.

[0037] Due to the adoption of the above technical solution, the beneficial effects obtained by this application are as follows:

[0038] 1. The curtain guide rail structure in this application includes a guide rail body and a mounting seat. The mounting seat includes a clamping portion and a connecting portion. The clamping portion is in clamping fit with the guide rail body. A receiving opening is provided on the inner lining of the vehicle roof, and the connecting portion is in clamping fit with the inner lining through the receiving opening. Since the curtain guide rail structure in this application is assembled on the inner lining of the vehicle roof, compared with the original curtain in the prior art, the development cost of the curtain guide rail is reduced, the requirement for the vehicle development synchronization is reduced, and at the same time, the situation of reserving a mounting position on the white vehicle body is avoided, thus greatly reducing the cost of installing the curtain on the vehicle; in addition, compared with the solution of installing the curtain guide rail in the aftermarket, the situation of needing to use screws for fixing is avoided, the coordination between the curtain guide rail structure and the overall shape of the whole vehicle is increased, and at the same time, the stability of the curtain guide rail structure and the durability are increased.

[0039] 2. The connecting part in this application includes a first connecting section, a second connecting section, and a third connecting section located between the first connecting section and the second connecting section. The first connecting section and the second connecting section form a receiving space for the inner lining on opposite sides of the third connecting section. The clamping part is connected to the second connecting section. When installing the mounting seat, first align the first connecting section with the receiving opening, then insert the first connecting section through the receiving opening to the outside of the inner lining, and then rotate the mounting seat by 90 degrees, so that the first connecting section abuts against the outside of the inner lining. The third connecting section is located in the receiving opening, and the second connecting section is located inside the inner lining, that is, part of the inner lining is located in the receiving space, and then the connecting part is clamped and cooperated with the inner lining to complete the installation of the mounting seat. In this process, only the mounting seat needs to be pushed and rotated, which greatly reduces the installation difficulty of the mounting seat, improves the assembly efficiency of the mounting seat, and greatly reduces the difficulty of installing curtains on the vehicle; at the same time, after the guide rail body is clamped to the clamping part, the guide rail can also limit the mounting seat to avoid the situation that the connecting part contacts and is clamped and falls off due to the vibration of the vehicle, thus greatly ensuring the installation stability of the curtain guide rail structure.

[0040] 3. In this application, the length L1 of the first connecting section and the length L2 of the second connecting section satisfy: L1 > L2, which increases the stop cooperation area between the first connecting section and the inner lining, greatly avoids the situation that the first connecting section disengages from the outside of the inner lining through the receiving opening, thereby increasing the clamping cooperation stability between the connecting part and the inner lining, increasing the connection stability between the mounting seat and the inner lining, and thus increasing the connection stability between the curtain guide rail structure and the inner lining.

[0056] Referring to Figures 1 to 7 , a retrofit vehicle window curtain rail structure is disclosed, which includes a rail body 1 and a mounting seat 2. The mounting seat 2 includes a clamping portion 21 and a connecting portion 22. The clamping portion 21 is in clamping cooperation with the rail body 1. A receiving opening 31 is provided in the lining 3 of the vehicle roof, and the connecting portion 22 is in clamping cooperation with the lining 3 through the receiving opening 31.

[0057] When retrofitting a window curtain for a vehicle, first install the mounting seat 2 on the lining 3 of the vehicle roof so that the connecting portion 22 is in clamping cooperation with the lining 3 through the receiving opening 31, and then the lining 3 supports the mounting seat 2. Then, assemble the rail body 1 to the mounting seat 2 so that the rail body 1 is in clamping cooperation with the clamping portion 21. Finally, install the window curtain on the rail body 1 to complete the retrofitting of the window curtain for the vehicle.

[0058] Since the window curtain rail structure in this application is assembled to the lining 3 of the vehicle roof, compared with the original window curtain in the prior art, the development cost of the window curtain rail is reduced, the requirement for the vehicle development synchronization is reduced, and at the same time, the situation of reserving a mounting position on the white body is avoided, thus greatly reducing the cost of installing the window curtain on the vehicle. In addition, compared with the solution of retrofitting a window curtain rail in the aftermarket, the situation of needing to use screws for fixing is avoided, the coordination between the window curtain rail structure and the overall shape of the vehicle is increased, and at the same time, the stability of the window curtain rail structure is increased and the durability is increased.

[0059] This application does not specifically limit the structure of the connecting portion 22. Preferably, referring to Figure 3 , Figure 5 and Figure 6 , the connecting portion 22 includes a first connecting section 221, a second connecting section 222, and a third connecting section 223 located between the first connecting section 221 and the second connecting section 222. The first connecting section 221 and the second connecting section 222 form a receiving space 224 for receiving the lining 3 on opposite sides of the third connecting section 223, and the clamping portion 21 is connected to the second connecting section 222.

[0060] It can be understood that the first connecting segment 221 and the second connecting segment 222 are arranged relative to each other, and one end of the third connecting segment 223 is fixedly connected to the first connecting segment 221, and the other end of the third connecting segment 223 is fixedly connected to the second connecting segment 222, so that the first connecting segment 221 and the second connecting segment 222 are fixedly connected through the third connecting segment 223.

[0061] When installing the mounting base 2, first align the first connecting section 221 with the receiving opening 31, then extend the first connecting section 221 through the receiving opening 31 to the outside of the liner 3, and then rotate the mounting base 2 90 degrees, so that the first connecting section 221 is in contact with the outside of the liner 3, the third connecting section 223 is located in the receiving opening 31, and the second connecting section 222 is located on the inside of the liner 3, that is, part of the liner 3 is located in the receiving space 224, and then the connecting portion 22 is snap-fitted with the liner 3 to complete the installation. During the installation of the paired mounting bases 2, it is only necessary to push and rotate the mounting bases 2, thereby greatly reducing the difficulty of installing the mounting bases 2 and improving the assembly efficiency of the mounting bases 2, so as to greatly reduce the difficulty of installing curtains on the vehicle; at the same time, after the guide rail body 1 is clamped to the clamping portion 21, the guide rail can also limit the mounting base 2 to avoid the connection portion 22 and the lining 3 from contacting and clamping and falling due to the vibration of the vehicle, thereby greatly ensuring the installation stability of the curtain guide rail structure.

[0062] It should be noted that the inner side of the lining 3 mentioned in this application refers to the side of the lining 3 facing the interior space of the vehicle, that is, the side of the lining 3 away from the outer contour of the vehicle; and the outer side of the lining 3 refers to the side of the lining 3 facing the space outside the vehicle, that is, the side of the lining 3 facing the outer contour of the vehicle.

[0063] Further, refer to Figure 6 The length L1 of the first connecting section 221 and the length L2 of the second connecting section 222 satisfy: L1>L2, thereby increasing the stop fitting area between the first connecting section 221 and the lining 3, greatly avoiding the first connecting section 221 from escaping from the outside of the lining 3 through the accommodating opening 31, thereby increasing the snap-fitting stability between the connecting portion 22 and the lining 3, thereby increasing the connection stability between the mounting seat 2 and the lining 3, and thereby increasing the connection stability between the curtain guide rail structure and the lining 3.

[0064] Further, refer to Figure 4 and Figure 6 , the width D1 of the first connecting segment 221 , the width D2 of the second connecting segment 222 , the length L1 of the first connecting segment 221 , and the length L2 of the second connecting segment 222 satisfy: D1 < L2 < L1 < D2 .

[0065] Specifically, since the width of the second connecting section 222 is greater than the length of the first connecting section 221, after the connecting portion 22 is snap-fitted with the inner lining 3, the second connecting section 222 can block the accommodating opening 31, thereby increasing the aesthetic property of the vehicle interior, improving the user experience. At the same time, the width of the second connecting section 222 is greater than the width of the first connecting section 221, avoiding the situation where the second connecting section 222 extends to the outside of the inner lining 3 through the accommodating opening 31 when the first connecting section 221 extends to the outside of the inner lining 3 through the accommodating opening 31, thus greatly reducing the assembly difficulty of the mounting seat 2 and greatly improving the assembly efficiency of the mounting seat 2.

[0066] Further, referring to Figure 3 and Figure 6 , the length L3 of the third connecting section 223 and the thickness D of the inner lining 3 satisfy: D > L3 ≥ 0.9D, so that the distance between the first connecting section 221 and the second connecting section 222 is less than the thickness of the inner lining 3. After the connecting portion 22 is snap-fitted with the inner lining 3, the connecting portion 22 is in interference fit with the inner lining 3, further increasing the snap-fitting stability between the connecting portion 22 and the inner lining 3. At the same time, it avoids the noise generated by the relative shaking between the snap-fitting portion 21 and the inner lining 3 during the vehicle driving, ensuring the driving quality of the vehicle and thus ensuring the user experience.

[0067] Further, referring to Figure 6 , guiding surfaces 225 are provided on both sides of the first connecting section 221 facing the second connecting section 222, so that the thickness of both side edges of the second connecting section 222 gradually decreases in the direction away from the third connecting section 223, thereby increasing the opening size of the accommodating space 224. When the mounting seat 2 is rotated to make the connecting portion 22 snap-fitted with the inner lining 3, the guiding surfaces 225 can guide the inner lining 3 and the first connecting section 221, greatly reducing the difficulty of snap-fitting the connecting portion 22 with the inner lining 3. At the same time, it reduces the force required to rotate the mounting seat 2 when rotating the mounting seat 2, greatly improving the installation efficiency of the mounting seat 2, and avoiding the situation where the inner lining 3 may be damaged when rotating the mounting seat 2, ensuring the structural strength of the inner lining 3, and thus ensuring the supporting stability of the inner lining 3 for the curtain rail structure, greatly improving the stability of the curtain rail structure.

[0068] The present application does not specifically limit the structure of the third connecting section 223. Preferably, the circumferential surface of the third connecting section 223 has a guiding curved surface, thereby avoiding the interference between the third connecting section 223 and the wall of the receiving port 31 during the rotation of the mounting seat 2, increasing the smoothness of the rotation of the mounting seat 2, reducing the force required for rotating the mounting seat 2, greatly improving the assembly efficiency of the mounting seat 2, achieving the effect of facilitating the assembly of the mounting seat 2, and enabling the third connecting section 223 to abut against two opposite walls of the receiving port 31, avoiding the situation that there is a gap between the third connecting section 223 and two opposite walls of the receiving port 31, which may cause relative movement between the mounting seat 2 and the inner lining 3, further reducing the noise generated during vehicle driving and increasing the installation stability of the curtain rail structure.

[0069] The present application does not specifically limit the formation method of the guiding curved surface. Preferably, the cross-section of the third connecting section 223 is circular, and thus the outer circumferential surface of the third connecting section 223 constitutes the guiding curved surface. In other embodiments, the cross-section of the third connecting section 223 can also be oval or racetrack-shaped.

[0070] In other embodiments, the third connecting section 223 can also be Figure 5 square as shown in

[0071] In other embodiments, the connecting portion 22 can also be a snap structure, as long as it can achieve snap-fit with the inner lining 3.

[0072] In a preferred embodiment, referring to Figure 3 , Figure 5 , Figure 6 and Figure 7 , clamping grooves 11 are oppositely arranged on both sides of the guide rail body 1. The clamping portion 21 includes a supporting section 211 provided on the connecting portion 22 and clamping sections 212 provided on opposite sides of the supporting section 211. A clamping space for accommodating the guide rail body 1 is formed between the two clamping sections 212, and the two clamping sections 212 are respectively clamped in the two clamping grooves 11.

[0073] When installing the guide rail body 1, first align the guide rail body 1 with the opening of the clamping space, and then push the guide rail body 1 upward, so that the top of the guide rail body 1 enters the clamping space, and the two clamping sections 212 are respectively clamped in the two clamping grooves 11 to complete the installation of the guide rail body 1. In this process, only the guide rail body 1 needs to be pushed upward, thus greatly improving the installation efficiency of the guide rail body 1.

[0074] The present application does not specifically limit the formation method of the clamping grooves 11. Preferably, referring to Figure 7, the wall bodies on both sides of the top of the guide rail body 1 are recessed towards the inside of itself to form an avoidance space, and the top wall body of the guide rail body 1 extends towards both sides to form a blocking wall body 12. The blocking wall body 12 and the avoidance space together form a clamping groove 11. The distance K between the two ends of the blocking wall body 12 facing away from each other and the width W of the guide rail body 1 satisfy: K < W.

[0075] Since the distance between the two ends of the blocking wall body 12 facing away from each other is less than the width of the guide rail body 1, the width of the top of the guide rail body 1 is reduced. Then, when the guide rail body 1 is assembled to the clamping part 21, the blocking wall body 12 can guide the guide rail body 1, so that the guide rail body 1 can more easily enter the clamping space and be clamped with the clamping section 212, greatly reducing the installation difficulty of the guide rail body 1, and further improving the installation efficiency of the guide rail body 1.

[0076] Further, referring to Figure 2 、 Figure 4 and Figure 5 , the clamping section 212 includes a limiting wall body 213 connected to the supporting section 211 and an elastic wall body 214 provided on the limiting wall body 213. The elastic wall body 214 is clamped in the clamping groove 11.

[0077] When assembling the guide rail body 1, first align the guide rail body 1 with the opening of the clamping space, and then push the guide rail body 1 upward so that the guide rail body 1 abuts against the elastic wall body 214. Continue to push the guide rail body 1, so that the elastic wall body 214 undergoes elastic deformation, and one end of the top of the guide rail body 1 enters the clamping space. Then the elastic wall body 214 resumes deformation and extends into the clamping groove 11 to be clamped with the groove wall of the clamping groove 11 to complete the installation of the guide rail body 1. Due to the existence of the elastic wall body 214, the force required for assembling the guide rail body 1 is reduced, and the installation efficiency of the guide rail body 1 is greatly improved.

[0078] Preferably, the wall surface of the avoidance space is curved so that the depth of the avoidance space gradually increases from bottom to top. The shape of the elastic wall body 214 is adapted to the wall surface of the avoidance space to increase the clamping stability between the two.

[0079] In a preferred embodiment, the clamping part 21 is provided with an elastic limiting part 23, and the elastic limiting part 23 can abut against the guide rail body 1 to apply an elastic force to the guide rail body 1 in a direction away from the connecting part 22.

[0080] After the guide rail body 1 is installed on the clamping part 21, the elastic limiting part 23 abuts against the guide rail body 1 and applies a force to the guide rail body 1 in a direction away from the connecting part 22, thereby clamping the guide rail body 1 and the clamping part 21 tightly, so as to prevent the guide rail body 1 and the clamping part 21 from relatively shaking in the vertical direction, which may cause the guide rail body 1 to be fixed insecurely. Furthermore, the fixing stability of the guide rail body 1 is greatly increased. At the same time, the stability of the mounting seat 2 can also be increased, and the situation of generating noise due to the relative movement between the mounting seat 2 and the guide rail can be avoided.

[0081] This application does not specifically limit the structure of the elastic limiting part 23. Preferably, referring to Figure 2 , Figure 4 and Figure 5 , the elastic limiting part 23 is an elastic piece arranged at both ends of the clamping part 21, and the elastic piece extends obliquely in a direction approaching the guide rail body 1 along a direction away from the clamping part 21.

[0082] Since the elastic limiting part 23 is an elastic piece arranged at both ends of the clamping part 21, on the one hand, the structure of the elastic limiting part 23 is simplified, so as to reduce the production difficulty and production cost of the mounting seat 2. At the same time, the elastic contact points between the clamping part 21 and the guide rail body 1 are increased, so as to further increase the connection stability between the guide rail body 1 and the clamping part 21. In addition, the assembly difficulty of the guide rail body 1 can also be reduced.

[0083] In other embodiments, the elastic limiting part 23 can also be an elastic structure arranged on the clamping part 21, such as a spring, an elastic column, and the like.

[0084] In a preferred embodiment, referring to Figure 3 and Figure 5 , an included angle is formed between the connecting part 22 and the clamping part 21, so that the opening of the guide rail body 1 faces downward.

[0085] Since the position where the vehicle needs to install the curtain is usually on the side of the interior space of the vehicle, and the inner lining 3 on the side is usually bent, setting the connecting part 22 and the clamping part 21 to form an included angle can make the installation direction of the guide rail body 1 vertically upward and the opening of the guide rail body 1 downward, so as to ensure the smoothness of pulling the curtain, and thus improve the user experience.

[0086] Furthermore, referring to Figure 4 and Figure 5 , a reinforcing rib 24 is arranged between the connecting part 22 and the clamping part 21. The reinforcing rib 24 is fixedly connected to the connecting part 22 and the clamping part 21 to increase the connection stability between the connecting part 22 and the clamping part 21, and thus ensure the fixing effect on the guide rail body 1.

[0087] In a preferred embodiment, referring to Figure 1, A plurality of mounting seats 2 are arranged at intervals along the length direction of the guide rail body 1, thereby increasing the fixed points of the guide rail body 1, thus increasing the stability of the guide rail body 1 to further increase the stability of the curtain rail structure, and at the same time enabling the structure of the mounting seat 2 to be as small as possible to ensure the structural strength of the inner lining 3 and increase the connection stability between the mounting seat 2 and the inner lining 3.

[0088] In a preferred embodiment, a plurality of sliders for hanging curtains are slidably connected in the guide rail body 1, and magnets are arranged on both sides of each slider; or, magnets are arranged on one side of each slider, and iron sheets are arranged on the other side of each slider, so that adjacent two sliders can be magnetically connected.

[0089] Since magnets are arranged on both sides of each slider; or, magnets are arranged on one side of each slider and iron sheets are arranged on the other side of each slider, after the curtain is pulled to the storage position, adjacent two sliders can be magnetically attracted together to increase the stability of the curtain moving to the storage position, avoid the situation that the slider moves along the guide rail body 1 during the vehicle driving and affects the driver's line of sight, and further increase the driving safety of the vehicle; at the same time, it can also make the sliders at the mutually approaching ends of the two curtains be magnetically connected together after the curtain is pulled to the closed position, so as to avoid the situation of curtain gaps, and further improve the user experience.

[0090] Preferably, in this application, the scheme of arranging magnets on both sides of each slider is adopted to reduce the installation difficulty of the slider.

[0091] In this application, the places not described can be realized by adopting or referring to the existing technologies.

[0092] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between each embodiment can be referred to each other. The key points of each embodiment are the differences from other embodiments.

[0093] The above description is only for the embodiments of this application and is not intended to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the scope of the claims of this application.
