Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, in particular to an integrated sunroof sunshade structure and a vehicle. BACKGROUND

[0002] The existing manual sunroof sunshade curtain sunroof assembly structure usually includes: a sunroof lower cover, a sunshade curtain, a sunshade curtain middle beam, sunshade curtain beam two side sliding blocks and mounting structures, sunshade curtain two side guide rails and mounting structures, a sunroof frame, a sunroof glass assembly, etc. The sunshade curtain guide rail and the sunshade curtain are usually mounted on the sunroof lower cover or the sunroof frame. The fixed position of the sunshade curtain after being opened is realized by the sliding blocks at both ends of the sunshade curtain beam being clamped into the guide rail slot of the sunshade curtain.

[0003] However, as shown in the prior art, the existing manual sunroof sunshade curtain structure has the following problems: Figure 1 The existing manual sunroof sunshade curtain structure has a large number of structure parts, including a sliding rail 2, a sunshade curtain sliding block 31, a screw for mounting the sunshade curtain guide rail, etc., and the assembly process is long. The relative accuracy of the two side sliding rails 2 and the sunshade curtain is not easy to guarantee, and problems such as sunshade curtain rolling and jamming and sunshade curtain operation not smooth are prone to occur. The sliding block fixing structure after the sunshade curtain is opened is not convenient to operate. When the sunshade curtain is opened, the sunshade curtain can only be kept in the sunshade curtain opening position when the sunshade curtain handle is manually operated to pull the beam to the appropriate position and the limiting structure of the sunshade curtain sliding block 31 at both ends of the sunshade curtain beam is clamped into the opening slot of the guide rail at the same time. When the force of the manual operator operating the handle is not perpendicular to the sunshade curtain opening direction, the two side sliding blocks are prone to be out of synchronization and cannot be smoothly inserted into the slot of the two side sliding rails 2 at the same time. When the sunshade curtain sliding block is clamped to the insufficient depth of the sliding rail slot, the automatic rebound fault is prone to occur during the driving of the automobile. SUMMARY

[0004] In view of the defects in the prior art, the purpose of the present application is to provide an integrated sunroof sunshade structure and a vehicle, which can solve the problem that the sunshade curtain sliding block is clamped to the insufficient depth of the sliding rail slot, and the automatic rebound problem is prone to occur during the driving of the automobile.

[0005] To achieve the above purpose, the technical scheme adopted by the present application is as follows:

[0006] On the one hand, the present application provides an integrated sunroof sunshade structure, comprising:

[0007] a sunroof lower cover, a sunshade curtain, a sunshade curtain middle beam, sunshade curtain beam two side sliding blocks and mounting structures, sunshade curtain two side guide rails and mounting structures, a sunroof frame, a sunroof glass assembly, etc. The sunshade curtain guide rail and the sunshade curtain are usually mounted on the sunroof lower cover or the sunroof frame. The sunshade curtain after being opened is realized by the sliding blocks at both ends of the sunshade curtain beam being clamped into the guide rail slot of the sunshade curtain.

[0008] Two slide rails are arranged along the direction of the pull-up sunshade curtain and located at both sides of the window in the direction of the pull-up sunshade curtain and connected with the sunroof lower cover, the slide rail is provided with a sliding groove facing the window and at least one limiting slot communicated with the sliding groove, the sliding groove comprises a straight section and a raised section corresponding to the limiting slot, one end of the raised section is connected with the straight section and the other end is raised away from the car compartment along the direction of the pull-up sunshade curtain, the limiting slot is communicated with the raised end of the raised section and extends to the extension line of the straight section;

[0009] A sliding rod is slidably arranged in the sliding groove and clamped in the limiting slot.

[0010] In some optional solutions, the angle between the extending direction of the limiting slot and the straight section is obtuse.

[0011] In some optional solutions, the width of the straight section and the raised section is greater than the diameter of the sliding rod.

[0012] In some optional solutions, the limiting slot comprises a guiding area and a limiting area, the guiding area is connected with the sliding groove, the width of the guiding area is greater than the diameter of the sliding rod, the limiting area is matched with the shape of the sliding rod in shape and the guiding area and the limiting area are smoothly connected.

[0013] In some optional solutions, a limiting protrusion is arranged in the limiting area and the end of the sliding rod is provided with a positioning slot matched with the limiting protrusion.

[0014] In some optional solutions, the starting end of the sliding groove in the direction of the pull-up sunshade curtain is a gradual change section, the width of the gradual change section gradually increases from being matched with the sliding rod to being the same as the straight section.

[0015] In some optional solutions, when the limiting slot is located in the middle of the sliding groove, the raised section corresponding to the limiting slot is provided with a straight section at both ends, the raised end of the raised section is connected with the straight section through a downward sliding section and the limiting slot is communicated with the downward sliding section.

[0016] In some optional solutions, the raised section and the downward sliding section are smoothly connected in an arc shape.

[0017] In some optional solutions, the position where the limiting slot in the middle of the sliding groove is communicated with the downward sliding section is located at the end where the downward sliding section is connected with the raised section.

[0018] In another aspect, the application further provides a vehicle comprising the integrated sunroof sunshade structure.

[0019] Compared with existing technologies, the advantages of this invention are as follows: When it is necessary to restrict the position of the sunshade, the sliding rod is slid into the corresponding limiting groove. Since the sliding groove includes a straight section and a raised section corresponding to the limiting groove, one end of the raised section is connected to the straight section, and the other end raises away from the vehicle compartment along the direction of pulling up the sunshade. The limiting groove communicates with the raised end of the raised section and extends to the extension line of the straight section. When the sliding rod slides into the corresponding limiting groove, it is blocked by the raised section and will not come out of the limiting groove, slide back into the straight section, and be rolled up by the retracting rod. This prevents the sunshade from being rolled up due to vibrations during vehicle operation, improving the stability of use. Furthermore, since the limiting groove extends to the extension line of the straight section, when the sliding rod slides into the limiting groove, the sliding rod is flush with the straight section, which can ensure that the sunshade maintains a flat state when it is in any limited position. The limiting groove will not cause the sunshade to be uneven when it is opened to the set position, thus ensuring the aesthetics of the car interior when the sunshade is open.

[0027] In order to make the purposes, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0028] The embodiments of the present application will be further described below with reference to the drawings.

[0029] As shown in Figure 2 , Figure 3 and Figure 4 , the present application provides an integrated sunroof sunshade structure, which comprises a sunroof lower cover 1, a sliding rod 3, and two slide rails 2. The sunroof lower cover 1 is provided with a window 11. The two slide rails 2 are arranged along the direction in which a sunshade curtain is pulled up and are located on both sides of the window 11 in the direction in which the sunshade curtain is pulled up, and are connected with the sunroof lower cover 1. The slide rail 2 is provided with a sliding groove 21 facing the window 11 and at least one limiting groove 22 communicating with the sliding groove 21. The sliding groove 21 comprises a straight section 211 and a raised section 212 corresponding to the limiting groove 22. One end of the raised section 212 is connected with the straight section 211, and the other end is raised away from the side of the vehicle compartment in the direction in which the sunshade curtain is pulled up. The limiting groove 22 communicates with the raised end of the raised section 212 and extends to the extension line of the straight section 211. The sliding rod 3 is slidably arranged at both ends in the sliding groove 21 and can be clamped in the limiting groove 22.

[0030] In use of the integrated sunroof sunshade structure, one limiting groove 22 is arranged at the end of the sliding groove 21, and a winding rod 4 is arranged at the starting end of the sliding groove 21. The winding rod 4 is rotatable relative to the sliding groove 21. The sunshade curtain is wound on the winding rod 4, and one end of the sunshade curtain is fixedly connected with the winding rod 4, and the other end is connected with the sliding rod 3. The two ends of the winding rod 4 are rotatably connected with the slide rail 2 or the sunroof lower cover 1, and are connected with the sliding groove 21 or the sunroof lower cover 1 through a winding spring. One end of the winding spring is connected with the winding rod 4, and the other end is connected with the sliding groove 21 or the sunroof lower cover 1, for providing a winding force for the winding rod 4. The limiting grooves 22 are arranged at the set limiting positions, and the limiting grooves 22 on both sides are arranged at the corresponding positions of the entire sliding groove 21. One limiting groove 22 is arranged at the end of the sliding groove 21. The number and positions of the limiting grooves 22 are determined according to actual requirements and settings.

[0031] When the sunshade curtain needs to be pulled up, the sliding rod 3 is manually pulled, and the two ends of the sliding rod 3 slide in the sliding grooves 21 of the sliding rails 2 on both sides of the window 11 in the direction of pulling up the sunshade curtain. When the position of the sunshade curtain needs to be limited, the sliding rod 3 is slid into the limiting groove 22 at the corresponding position. Since the sliding groove 21 includes a flat section 211 and a raised section 212 corresponding to the limiting groove 22, one end of the raised section 212 is connected to the flat section 211, and the other end is raised away from the vehicle compartment in the direction of pulling up the sunshade curtain. The limiting groove 22 is in communication with the raised end of the raised section 212 and extends to the extension line of the flat section 211. When the sliding rod 3 is slid into the limiting groove 22 at the corresponding position, it is blocked by the raised section 212 and cannot fall out of the limiting groove 22. When it is slid into the flat section 211 again, it is rolled up by the rolling rod 4. The sunshade curtain cannot be rolled up due to vibration during vehicle driving, improving the stability of use. Moreover, since the limiting groove 22 extends to the extension line of the flat section 211, when the sliding rod 3 is slid into the limiting groove 22, the sliding rod 3 is flush with the flat section 211, which can ensure that the sunshade curtain maintains a flush state at any limited position, and the sunshade curtain will not be uneven when it is opened to the set position due to the limiting groove, thereby realizing the beauty of the interior when the sunshade curtain is opened.

[0032] In this example, pulling up the sunshade curtain refers to unfolding the sunshade curtain, and retracting the sunshade curtain refers to folding up the sunshade curtain.

[0033] In addition, a plurality of limiting grooves 22 can be arranged between the end and the starting end of the sliding groove 21, and a plurality of raised sections 212 can be correspondingly arranged, so as to limit the sliding rod 3 at different positions, that is, to realize different opening degrees of the sunshade curtain.

[0034] In some optional embodiments, the angle between the extension direction of the limiting groove 22 and the flat section 211 is obtuse.

[0035] In the embodiments, the limiting groove 22 extends to the extension line of the flat section 211, and the angle between the extension direction of the limiting groove 22 and the flat section 211 is obtuse, that is, the limiting groove 22 is inclined to the starting end of the sliding groove 21, forming an inverted hook groove. When the sliding rod 3 is slid into the limiting groove 22, the sliding rod 3 is limited, which can further prevent the sliding rod 3 from falling off the limiting position. Of course, in other embodiments, the limiting groove 22 can also be arranged to extend in the vertical direction of the flat section 211, which can also have a similar effect, but in this way, the sliding rod 3 has a certain risk of falling off.

[0036] In some optional embodiments, the width of the flat section 211 and the raised section 212 is greater than the diameter of the sliding rod 3.

[0037] In the existing scheme, the sunshade curtain slider cooperates with the guide rail, the relative accuracy of the two side guide rails and the sunshade curtain slider is not easy to guarantee, and problems such as jamming of the sunshade curtain during winding and unsmooth operation of the sunshade curtain are prone to occur; and the operation convenience of the slider fixing structure after the sunshade curtain is opened is poor. When the sunshade curtain is opened, the sunshade curtain handle needs to be manually operated to pull the cross beam to the appropriate position, and the slider limiting structure at both ends of the sunshade curtain cross beam needs to be simultaneously clamped into the opening clamping groove of the guide rail, and the sunshade curtain can only be kept in the sunshade curtain opening position. When the manual operator operates the handle in a direction that is not perpendicular to the sunshade curtain opening direction, the two side sliders are prone to be out of sync and cannot simultaneously and smoothly enter the clamping grooves of the two side guide rails.

[0038] In the present scheme, the two ends of the sliding rod 3 always slide in the sliding groove 21 of the sliding rail 2, and the width of the flat section 211 and the raised section 212 is greater than the diameter of the sliding rod 3. Even if the two ends of the sliding rod 3 are slightly out of sync, the sliding rod 3 will not be jammed, improving user experience and operation convenience.

[0039] As shown in Figure 4 In some optional embodiments, the limiting groove 22 includes a guide area 221 and a limiting area 222. The guide area 221 is connected with the sliding groove 21, and the width of the guide area 221 is greater than the diameter of the sliding rod 3. The shape of the limiting area 222 matches the shape of the sliding rod 3, and the guide area 221 and the limiting area 222 are smoothly connected.

[0040] In the present embodiment, in order to avoid the sliding rod 3 from shaking in the limiting groove 22 due to vehicle vibration when the sliding rod 3 is located in the limiting groove 22, causing the sliding rod 3 to emit abnormal noise in the limiting groove 22, which will cause the user experience to decrease. Since the width of the flat section 211 and the raised section 212 of the sliding groove 21 is greater than the diameter of the sliding rod 3, if the width of the limiting groove 22 is directly designed to be the same as the diameter of the sliding rod 3, it will be difficult for the sliding rod 3 to be clamped into the limiting groove 22. In the present scheme, the width of the guide area 221 is designed to be greater than the diameter of the sliding rod 3, the shape of the limiting area 222 matches the shape of the sliding rod 3, and the guide area 221 and the limiting area 222 are smoothly connected. When the sliding rod 3 is slid into the limiting groove 22, the sliding rod 3 is first slid into the guide area 221 with a width greater than the diameter of the sliding rod 3, and then the sliding rod 3 is slid into the limiting area 222 with a shape matching the sliding rod 3, and the guide area 221 and the limiting area 222 are smoothly connected. This way, the sliding rod 3 can be more easily slid into the limiting groove 22. In addition, the limiting area 222 is located on the extension line of the flat section 211, and when the sliding rod 3 is slid into the limiting area 222, the sliding rod 3 is flush with the flat section 211, which can ensure that the sunshade curtain maintains a flush state when it is in any limited position, thereby achieving the purpose of ensuring the beauty of the vehicle interior when the sunshade curtain is opened.

[0041] In some optional embodiments, a limiting protrusion 223 is arranged in the limiting area 222 of the limiting groove 22, and the end of the sliding rod 3 is provided with a positioning slot matched with the limiting protrusion 223.

[0042] In the embodiment, the limiting protrusion 223 is arranged in the limiting area 222 of the limiting groove 22, and the end of the sliding rod 3 is provided with a positioning slot matched with the limiting protrusion 223. When the limiting protrusion 223 is clamped in the limiting area 222, the limiting protrusion 223 is clamped in the positioning slot, so that the sliding rod 3 and the limiting groove 22 are prevented from shaking and generating noise, and the user experience is improved.

[0043] As shown in Figure 5 In some optional embodiments, the starting end of the sliding groove 21 in the direction of pulling up the sunshade curtain is a gradual change section 214, and the width of the gradual change section 214 gradually increases from being matched with the sliding rod 3 to being the same as the flat section 211.

[0044] In the embodiment, when it is needed to change the sunshade curtain from the pulled-up state to the retracted state, the sliding rod 3 is taken out of the limiting area 222, the starting end of the sliding groove 21 in the direction of pulling up the sunshade curtain provides a winding force to the sunshade curtain, the sunshade curtain is wound, so as to drive the sliding rod 3 to move to the starting end in the direction of pulling up the sunshade curtain, and finally make the sliding rod 3 enter the gradual change section 214 from the flat section 211. Since the width of the gradual change section 214 gradually increases from being matched with the sliding rod 3 to being the same as the flat section 211, the sliding rod 3 is clamped at the starting end in the direction of pulling up the sunshade curtain, and the diameter of the sliding rod 3 is the same, the sliding rod 3 is well clamped at the starting end of the sliding groove 21 in the direction of pulling up the sunshade curtain, and the abnormal sound caused by vibration during driving of the vehicle is avoided. In addition, since the width of the gradual change section 214 gradually increases from being matched with the sliding rod 3 to being the same as the flat section 211, the width of the flat section 211 and the raised section 212 is greater than the diameter of the sliding rod 3, and the sliding groove 21 will not be clamped with the sliding rod 3. In addition, the starting end of the sliding groove 21 in the direction of pulling up the sunshade curtain is also provided with a limiting protrusion matched with the positioning slot of the end of the sliding rod 3, so as to further improve the stability of the sliding rod 3 at the starting end of the sliding groove 21.

[0045] As shown in Figure 3 and 4 In some optional embodiments, when the limiting groove 22 is located in the middle of the sliding groove 21, the raised section 212 corresponding to the limiting groove 22 is provided with flat sections 211 at both ends, one end of the raised section 212 is connected with the flat section 211 through the downward sliding section 213, and the limiting groove 22 is communicated with the downward sliding section 213.

[0046] In the present embodiment, when the limiting groove 22 needs to be arranged in the middle part of the sliding groove 21, a plurality of straight sections 211 are arranged on the limiting groove 22, the limiting groove 22 extends to the extension line of the corresponding straight section 211, and the extending direction of the limiting groove 22 forms an obtuse angle with the extension line of the corresponding straight section 211. The straight section 211 corresponding to the limiting groove 22 is a straight section 211 close to the starting end of the sliding groove 21. The limiting groove 22 arranged in the middle part of the sliding groove 21 is also arranged behind the raised section 212, and a descending section 213 is arranged at one end of the raised section 212, and the descending section 213 is connected with the next straight section 211. Through the design, when the sunshade curtain does not need to be pulled up as a whole, the sliding rod 3 can smoothly pass through the limiting groove 22 in the middle part, and the comfort of the lifting operation is improved. In the present embodiment, the raised section 212 and the descending section 213 are equivalent to arching between the straight sections 211, and the limiting groove 22 is arranged at the descending section 213, so that the sliding rod 3 can be ensured to fall out of the limiting groove 22.

[0047] In some optional embodiments, the raised section 212 and the descending section 213 are smoothly connected through a circular arc.

[0048] In the present embodiment, the raised section 212 and the descending section 213, the raised section 212 and the straight section 211, and the descending section 213 and the straight section 211 are smoothly connected through a circular arc, so that the fluency of the user during use is improved.

[0049] In some optional embodiments, the position where the limiting groove 22 arranged in the middle part of the sliding groove 21 communicates with the descending section 213 is located at the end where the descending section 213 is connected with the raised section 212.

[0050] In the present embodiment, the position where the limiting groove 22 arranged in the middle part of the sliding groove 21 communicates with the descending section 213 is arranged at the end where the descending section 213 is connected with the raised section 212, so that the guiding area 221 and the limiting area 222 of the limiting groove 22 have a flowing space, the limiting area 222 is ensured to be located on the extension line of the straight section 211, and the arching height of the raised section 212 is ensured to be as low as possible, so that the vehicle body space is avoided.

[0051] In some optional embodiments, the sliding rail 2 and the sunroof lower cover 1 are integrally formed.

[0052] In the present embodiment, the sliding rail 2 and the sunroof lower cover 1 are integrally formed, so that the manufacturing precision is improved.

[0053] In addition, the slide rail 2 has a U-shaped cross-section, including a base plate and two spaced-apart sidewalls connected to the base plate, and the base plate and the two spaced-apart sidewalls forming a U-shaped groove, i.e., a sliding groove. The two spaced-apart sidewalls are an upper wall plate and a lower wall plate. At the location where the limiting groove 22 is provided, the upper wall plate and the lower wall plate arch upward to form a raised section 212 and a lower sliding section 213, and an opening is provided on the lower wall plate to connect to the limiting groove 22. When the user needs to engage the sliding rod 3 into the next limiting groove 22, the sliding rod 3 is pressed against the lower wall plate of the slide rail 2 as it slides along the previous straight section 211 and the raised section 212 corresponding to the limiting groove 22. In this way, when the sliding rod 3 passes through the limiting groove 22 connected to the lower wall plate, it will smoothly engage into the limiting groove 22. When the user does not need to engage the sliding rod 3 into the next limiting groove 22, the sliding rod 3 can be pressed against the upper wall plate of the slide rail 2. In this way, when the sliding rod 3 passes through the limiting groove 22 connected to the lower wall plate at the raised position, it will not engage into the limiting groove 22, but will smoothly slide through the limiting groove 22.

[0054] On the other hand, the present invention also provides a vehicle comprising: any of the above-described integrated sunroof sunshade structures.

[0055] When using this integrated sunroof shading structure, one of the limiting grooves 22 is set at the end of the slide rail 21, and a retractable rod 4 is set at the beginning of the slide rail 21. The retractable rod 4 can rotate relative to the slide rail 21. A sunshade curtain is rolled up on the retractable rod 4, and one end of the sunshade curtain is fixedly connected to the retractable rod 4, while the other end is connected to the sliding rod 3. Both ends of the retractable rod 4 are rotatably connected to the slide rail 21 or the lower sunroof cover 1, and are also connected to the slide rail 21 or the lower sunroof cover 1 through a coil spring. One end of the coil spring is connected to the retractable rod 4, and the other end is connected to the slide rail 21 or the lower sunroof cover 1, which is used to provide retracting force to the retractable rod 4. The limiting groove 22 is set at a set limiting position, and the limiting grooves 22 on both sides are set at corresponding positions on the entire slide rail 21. One limiting groove 22 is set at the end of the slide rail 21. The number and position of the limiting grooves 22 are determined according to actual needs and settings.

[0056] When the sunshade curtain needs to be pulled up, the sliding rod 3 is manually pulled, and the two ends of the sliding rod 3 slide in the sliding groove 21 of the sliding rail 2 on both sides of the window 11 in the direction of pulling up the sunshade curtain. When the position of the sunshade curtain needs to be limited, the sliding rod 3 is slid into the limiting groove 22 at the corresponding position. Since the sliding groove 21 includes a flat section 211 and a raised section 212 corresponding to the limiting groove 22, one end of the raised section 212 is connected with the flat section 211, and the other end is raised away from the vehicle compartment in the direction of pulling up the sunshade curtain. The limiting groove 22 is in communication with the raised end of the raised section 212 and extends to the extension line of the flat section 211. When the sliding rod 3 is slid into the limiting groove 22 at the corresponding position, it is blocked by the raised section 212 and cannot be pulled out of the limiting groove 22. When it is slid into the flat section 211 again, it is rolled up by the rolling rod 4. The sunshade curtain cannot be rolled up due to vibration during vehicle driving, and the stability of use is improved. Moreover, since the limiting groove 22 extends to the extension line of the flat section 211, the sliding rod 3 is flush with the flat section 211 when it is slid into the limiting groove 22. When the sunshade curtain is in any limited position, it can maintain a flush state, and the sunshade curtain will not be in an uneven state when it is opened to the set position due to the setting of the limiting groove, thereby realizing the beauty of the interior when the sunshade curtain is opened.

[0057] In addition, a plurality of limiting grooves 22 can be arranged between the end and the starting end of the sliding groove 21, and a plurality of raised sections 212 can be correspondingly arranged, so as to limit the sliding rod 3 at different positions, that is, to realize different opening degrees of the sunshade curtain.

[0058] The limiting groove 22 extends to the extension line of the flat section 211, and the extension direction of the limiting groove 22 forms an obtuse angle with the flat section 211, that is, the limiting groove 22 is inclined to the starting end of the sliding groove 21, forming an inverted hook groove. When the sliding rod 3 is slid into the limiting groove 22, the limiting of the sliding rod 3 is realized. Such a design can further prevent the sliding rod 3 from falling off from the limiting position.

[0059] The two ends of the sliding rod 3 always slide in the sliding groove 21 of the sliding rail 2, and the width of the flat section 211 and the raised section 212 is greater than the diameter of the sliding rod 3. Even if the two ends of the sliding rod 3 are slightly out of sync, the sliding rod 3 will not be stuck, improving the user experience and the convenience of operation.

[0060] In order to avoid the sliding rod 3 from shaking in the limiting groove 22 when the vehicle vibrates, causing the sliding rod 3 to make abnormal noise in the limiting groove 22, which will cause the user experience to decline. Since the width of the straight section 211 and the raised section 212 of the sliding groove 21 is greater than the diameter of the sliding rod 3, if the width of the limiting groove 22 is directly designed to be the same as the diameter of the sliding rod 3, it will be difficult for the sliding rod 3 to be clamped into the limiting groove 22. In this scheme, the width of the guide area 221 is designed to be greater than the diameter of the sliding rod 3, the shape of the limiting area 222 matches the shape of the sliding rod 3, and the guide area 221 and the limiting area 222 are smoothly transitioned. When sliding the sliding rod 3 into the limiting groove 22, first slide the sliding rod 3 into the guide area 221 with a width greater than the diameter of the sliding rod 3, and then slide the sliding rod 3 into the limiting area 222 matching the shape of the sliding rod 3, and the guide area 221 and the limiting area 222 are smoothly transitioned. In this way, the sliding rod 3 can be more easily slid into the limiting groove 22. In addition, the limiting area 222 is located on the extension line of the straight section 211, and when the sliding rod 3 is slid into the limiting area 222, the sliding rod 3 is flush with the straight section 211, which can ensure that the sunshade curtain maintains a flush state when it is in any limited position, thereby ensuring the beauty of the interior when the sunshade curtain is opened.

[0061] When a limiting groove 22 needs to be arranged in the middle of the sliding groove 21, a plurality of straight sections 211 are arranged on the limiting groove 22, the limiting groove 22 extends to the extension line of the corresponding straight section 211, and the angle between the extension direction of the limiting groove 22 and the extension line of the corresponding straight section 211 is obtuse. The straight section 211 corresponding to the limiting groove 22 is a straight section 211 close to the starting end of the sliding groove 21. The limiting groove 22 arranged in the middle of the sliding groove 21 is also arranged behind the raised section 212, and a downward sliding section 213 is arranged at one end of the raised section 212, which is connected with the next straight section 211 through the downward sliding section 213. This design can make the sliding rod 3 smoothly pass through the limiting groove 22 in the middle without the need to lift the sunshade curtain, improving the comfort of operation. In this example, the raised section 212 and the downward sliding section 213 are equivalent to arching between the straight sections 211, and the limiting groove 22 is arranged at the downward sliding section 213, which can ensure that the sliding rod 3 falls out of the limiting groove 22.

[0062] The raised section 212, the raised section 212 and the straight section 211, and the straight section 211 are smoothly transitioned with circular arcs, which can improve the smoothness of the user during use.

[0063] The position where the limiting groove 22 in the middle of the sliding groove 21 is communicated with the lower sliding section 213 is arranged at the end where the lower sliding section 213 is connected with the upturned section 212, so as to provide the guiding area 221 and the limiting area 222 of the limiting groove 22 with outflow space, ensure that the limiting area 222 is located on the extension line of the flat section 211, and at the same time, ensure that the upturning height of the upturned section 212 is as low as possible, so as to avoid occupying the space of the vehicle body.

[0064] The cross section of the slide rail 2 is in U shape, including a bottom plate and two spaced apart side wall plates connected with the bottom plate, and the bottom plate and the two spaced apart side wall plates form a U-shaped groove, i.e. a sliding groove. The two spaced apart side wall plates are respectively an upper wall plate and a lower wall plate. At the position where the limiting groove 22 is arranged, the upper wall plate and the lower wall plate are arched upward to form the upturned section 212 and the lower sliding section 213, and an opening is arranged on the lower wall plate to connect the limiting groove 22. When the user needs to clamp the sliding rod 3 into the next limiting groove 22, the sliding rod 3 is pressed against the lower wall plate of the slide rail 2 when sliding on the previous flat section 211 and the upturned section 212 corresponding to the limiting groove 22, so that the sliding rod 3 is smoothly clamped into the limiting groove 22 when passing through the limiting groove 22 communicated with the lower wall plate; when the user does not need to clamp the sliding rod 3 into the next limiting groove 22, the sliding rod 3 can be pressed against the upper wall plate of the slide rail 2, so that the sliding rod 3 does not enter the limiting groove 22 when passing through the limiting groove 22 communicated with the arched lower wall plate, but smoothly slides through the limiting groove 22.
