Description

Technical Field

[0001] This application relates to the field of vehicle body structure technology, and in particular to a sliding vehicle rear cover assembly. Background Technology

[0002] A vehicle generally includes a suspension system, a power system, a transmission system, a steering system, and a body structure; among these, the body structure is used to create an enclosed space within the vehicle to provide shelter from wind and rain.

[0003] A vehicle body structure, referring to Figure 1 It includes a floor plate 1, with upward-extending front pillars 11 (also called A-pillars) on both sides of one end of the floor plate 1, and upward-extending rear pillars 12 (also called C-pillars) on both sides of the end of the floor plate 1 away from the front pillars 11. An upward-extending middle pillar 13 (also called B-pillar) is provided on the floor plate 1 between the front pillars 11 and the rear pillars 12. The upper ends of the front pillars 11, middle pillars 13, and rear pillars 12 are connected to the roof longitudinal beams 14, and the roof crossbeams 15 are connected between the roof longitudinal beams 14 on both sides. The roof longitudinal beams 14 and the roof are connected to the roof cover 141 on both sides. A windshield 16 is provided between the front pillars 11 on both sides, and a rear cover 17 (also called a rear cover) is provided between the rear pillars 12 on both sides. Doors (not shown in the figure) are provided between the front pillars 11 and the middle pillars 13, and between the middle pillars 13 and the rear pillars 12.

[0004] Reference Figure 2 The rear of the vehicle is generally equipped with a luggage compartment 2. To facilitate the loading and unloading of luggage, some models have a rear cover 17 with a rotating opening structure, that is, the upper end of the rear cover 17 is hinged to the roof crossbeam 15; the rear cover 17 is connected to the rear pillar 12 by a gas spring 171. In use, the luggage compartment 2 can be opened by rotating the rear cover 17 upwards for loading and unloading luggage.

[0005] Regarding the aforementioned technologies, the inventors believe that when the back cover needs to be rotated upwards to open and retrieve luggage in strong winds, the windward area of ​​the back cover tends to increase, resulting in a greater force exerted by the wind on the back cover, making it difficult to close. Therefore, improvements are needed. Summary of the Invention

[0006] The purpose of this application is to provide a sliding rear cover assembly for vehicles to improve the problem of the rear cover being difficult to close in windy conditions.

[0007] The sliding vehicle rear cover assembly provided in this application adopts the following technical solution:

[0008] A sliding rear cover assembly includes a rear cover and a support frame; one end of the support frame is a closing engagement portion, and the other end is an open engagement portion; the closing engagement portion is used to connect with the rear pillar of the vehicle body, and the open engagement portion is used to connect with the roof longitudinal beam of the vehicle body; the rear cover is provided with a guide post extending along its width direction, and the support frame is provided with a guide groove along its length direction that slides and engages with the guide post; the rear cover can be moved along the length direction of the guide groove to a position above the roof of the vehicle body to open the rear cover; the inner sidewall of the guide groove near the closing engagement portion is provided with a recess for the guide post to be embedded; when the guide post is embedded in the recess, the rear cover is in a closed state.

[0009] By adopting the above technical solution, in use, the rear cover is pulled upwards to move the guide post from the mounting groove into the guide groove. Then, the rear cover is moved towards the open mating part, and the guide post slides along the guide groove, allowing the rear cover to move to a position above the roof of the vehicle body, thus opening the trunk for loading and unloading luggage. When it is necessary to close the rear cover, it is pulled towards the closing mating part. When the guide post aligns with the mounting groove, the guide post moves downwards into the mounting groove, causing the rear cover to move down and close, thereby closing the trunk. During the opening or closing of the rear cover, it remains approximately horizontal, which helps reduce the possibility of an increase in the windward area of ​​the rear cover, thus reducing the possibility of an increase in the wind force on the rear cover, making it easier to open or close the rear cover in windy conditions.

[0010] Furthermore, compared to the conventional rotating tailgate, the sliding tailgate can slide to a position above the roof, thus increasing the operating space at the trunk opening and making it easier to load and unload luggage. Simultaneously, the sliding tailgate requires less overhead space than the conventional rotating tailgate, making it easier to open in low-lying environments. On the other hand, sliding the tailgate to a position above the roof further increases the view from the trunk opening. At this point, users can fold down the rear seats and lie down in the trunk to enjoy the view from the trunk opening; the view is much wider than viewing the scenery through the sunroof.

[0011] Optionally, the guide post is located at the end of the rear cover near the closing mating part; the end of the insert groove away from the guide groove is inclined towards the open mating part; a support rod is rotatably provided at the end of the rear cover away from the guide post, and the support rod is rotatably connected to a support block; the support frame is provided with a support groove along its length that slides with the support block; the support block is provided with a locking component for fixing the support rod; and the support frame is provided with a limiting block for abutting against the end wall of the support block near the guide post.

[0012] By adopting the above technical solution, when the rear cover needs to be opened, it is pulled backward and upward along the length of the recessed groove. At this time, the limiting block blocks the support block, and the support rod rotates relative to the support block to allow the rear cover to rise. After the rear cover rises, the locking assembly locks the support rod. Finally, the rear cover is pushed forward to allow the guide post to slide along the guide groove and the support block to slide along the support groove, thereby moving the rear cover towards the top of the vehicle body. During the process of the rear cover rising and the guide post moving from the recessed groove into the guide groove, the support rod provides support for the rear cover, which helps to reduce the amount of lifting force required for the rear cover, making the operation more convenient and labor-saving.

[0013] Optionally, the locking assembly includes a follower post and a movable post, both of which are connected to the support rod. The movable post is located on the side of the follower post closer to the guide post. The support block is provided with a follower groove that slides with the follower post and a movable groove that slides with the movable post along the length of the support frame. The inner wall of the movable groove near the guide post is provided with a locking groove for the movable post to be embedded. The end of the locking groove away from the movable groove is inclined in the direction away from the guide post. The end of the follower groove near the guide post extends upward and towards the guide post to form an extension groove. When the follower block moves into the extension groove, the movable post aligns with the locking groove.

[0014] By adopting the above technical solution, when the rear cover is opened, during the rear cover's backward movement, when the follower column moves into the extension groove and abuts against the inner wall of the extension groove, the support rod rotates around the follower column, and the moving column can automatically move into the locking groove. At this time, pushing the rear cover forward causes the moving column to abut against the inner wall of the locking groove and the follower column to abut against the inner wall of the extension groove, thereby fixing the support rod relative to the support block. When the rear cover is closed, after the guide column moves to the position of the insertion groove, pressing the rear cover downward causes the follower column to abut against the inner wall of the extension groove, and the support rod can rotate around the follower column, allowing the moving column to move from the locking groove into the moving groove. At this time, the follower column and the moving column can move forward relative to the support block along with the support rod and the rear cover until the guide column moves into the insertion groove, allowing the rear cover to close.

[0015] Optionally, the support block is slidably provided with an abutment post for abutting against the side of the bottom wall of the moving column away from the locking groove, and the abutment post is connected to an elastic abutment member for driving it to move in the direction of the moving column.

[0016] By adopting the above technical solution, when the rear cover is pushed forward, the follower post abuts against the inner wall of the upper side of the extension groove, causing the rear cover to generate torque on the support rod, thereby causing the end of the support rod near the moving post to tend to move upward; the abutting post abuts against the moving post, and the abutting post can restrict the upward movement of the moving post, thereby reducing the possibility that the moving post will separate from the locking groove and cause the end of the rear cover near the support rod to move downward, thus helping to ensure that the rear cover and the top cover of the vehicle body remain separated, so that the rear cover can slide relative to the top cover.

[0017] Optionally, the support block is slidably provided with a push rod for abutting against the moving column or support rod along the length direction of the locking groove, and the push rod is located above the locking groove; the push rod is connected to an elastic push member for driving it to move in the direction of the locking groove.

[0018] By adopting the above technical solution, when the moving column moves along the moving groove towards the locking groove, the moving column or support rod can abut against the pushing column to compress and deform the elastic pushing member; when the moving column is aligned with the locking groove, the elastic pushing member can automatically push against the moving column or drive rod to move the moving column into the locking groove; at the same time, the pushing rod can press against the moving column or support rod to reduce the risk of the moving column separating from the locking groove.

[0019] Optionally, the rear cover is rotatably provided with a driven rod at the end of the support rod away from the guide post, and the driven rod and the support rod are rotatably connected together by a connecting rod; the driven rod is provided with a driven post at the side of the connecting rod away from the rear cover, and the support frame is provided with a driven groove along its length to accommodate the driven post.

[0020] By adopting the above technical solution, the rear cover, support rod, driven rod, and connecting rod together form a four-bar linkage mechanism. When the rear cover is pressed down from one end of the guide post (i.e., the rear end of the vehicle), the support rod, connecting rod, and driven rod cooperate to make the rear cover move down synchronously as a whole. This helps reduce the possibility of the rear cover tilting and causing the guide post to jam against the inner wall of the mounting groove, making it easier to close the rear cover. At the same time, the driven rod can support the rear cover to improve its stability.

[0021] Optionally, a fixing post is provided at the end of the support frame away from the insertion groove. The fixing post is slidably connected to the support frame along the depth or width direction of the support groove. The fixing post is connected to an elastic fixing member for driving it to slide towards the support block. The support block is provided with a fixing groove for inserting one end of the fixing post. The end wall of the fixing post near the support block is inclinedly provided with a guide surface for abutting against the inner sidewall of the fixing groove.

[0022] By adopting the above technical solution, when the rear cover slides to the open mating part, the fixing groove and the fixing post are aligned, and the fixing post can be inserted into the fixing groove to restrict the movement of the support block. This helps to improve the stability of the rear cover in the fixed position, thereby improving the stability of the rear cover in the open position.

[0023] Optionally, the support block is provided with an elastic damping element for abutting against the inner wall of the support groove.

[0024] By adopting the above technical solution, the elastic damping component presses against the inner wall of the support groove under its own elastic force, which helps to increase the friction between the support block and the inner wall of the support groove. This helps to reduce the risk of relative sliding between the support block and the inner wall of the support groove, and improves the stability of the support block when it is parked in any position in the support groove. This makes it easier to adjust the size of the luggage compartment opening as needed.

[0025] Optionally, a drive rod is rotatably provided at one end of the rear cover near the guide post, the guide post is connected to the drive rod, and the guide post is connected to the rear cover through the drive rod; the drive rod is provided with a limit post, and the support frame is provided with a limit groove along its length for the limit post to be accommodated; the limit post is located on the side of the guide post away from the rear cover.

[0026] By adopting the above technical solution, when the rear cover is lifted upwards, the drive rod rotates around the limiting post when the limiting post abuts against the inner wall of the upper side of the limiting groove, allowing the guide post to automatically move into the guide groove, making the operation more convenient and labor-saving. After the guide post moves into the guide groove, the rear cover is released, and the limiting post abuts against the inner wall of the lower side of the limiting groove to support the drive rod, thereby keeping the guide post in the guide groove and reducing the possibility of the guide post falling into the embedding groove.

[0027] Optionally, the rear cover is rotatably provided with a cleaning scraper for abutting against the upper surface of the roof of the vehicle body, and the lower side of the cleaning scraper is inclined towards the open mating part; the rear cover is provided with a limiting strip for abutting against the side wall of the cleaning scraper on the side away from the open mating part.

[0028] By adopting the above technical solution, when the rear cover slides towards the open mating part, the limiting strip can restrict the rotation of the cleaning scraper, so that the lower side wall of the cleaning scraper remains in contact with the roof of the vehicle body, allowing the cleaning scraper to scrape dust and other debris from the upper surface of the roof. The scraped debris can slide down the windshield and then be cleaned away by the wipers. When the rear cover slides towards the closed mating part, the cleaning strip can rotate away from the limiting strip, allowing the cleaning strip to disengage from the upper surface of the roof of the vehicle body, which helps to reduce the risk of the cleaning scraper scraping debris from the roof into the passenger compartment.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. During the opening or closing of the rear cover, the rear cover can always remain in a nearly horizontal state, which helps to reduce the possibility of the rear cover's frontal area increasing, thereby reducing the possibility of the rear cover being subjected to increased wind force, making it easier to open or close the rear cover in windy environments.

[0031] 2. The movable column cooperates with the movable groove and the locking groove, and the follower column cooperates with the follower groove and the extension groove to realize the automatic locking and unlocking of the support rod. The structure is simple and the operation is convenient.

[0032] 3. The matching of the limiting post and the limiting groove facilitates the automatic movement of the guide post from the embedded groove to the guide groove, making the operation more convenient and labor-saving. Attached Figure Description

In another embodiment, the support groove may also be located above or below the mating groove 421; the support groove may also be formed on the guide plate 41.

[0055] Reference Figure 5 and Figure 6 A locking assembly 51 is provided between the support rod 331 and the support block 5. The locking assembly 51 includes a follower post 511 and a moving post 512. Both the follower post 511 and the moving post 512 are rotatably disposed on the side wall of the support rod 331 facing the support block 5, and the moving post 512 is located on the side of the follower post 511 closer to the guide post 3321. The side wall of the support block 5 facing the support rod 331 is provided with a follower groove 52 and a moving groove 53, both of which are opened along the length of the support bar 42. The inner side wall of the moving groove 53 near the guide post 3321 is provided with a locking groove 531 extending downwards. The end of the locking groove 531 away from the moving groove 53 extends in a direction away from the guide post 3321. The moving post 512 is located in the moving groove 53 and can move into the locking groove 531. The end of the follower groove 52 near the guide post 3321 extends upward and toward the guide post 3321 to form an extension groove 521; the follower post 511 is located in the follower groove 52 and can move into the extension groove 521.

[0056] Reference Figure 4 and Figure 5 The mounting rod 33 is hinged to a driven rod 333 on the side of the support rod 331 away from the driving rod 332. In this embodiment, the driven rod 333 has the same shape as the support rod 331, and the driven rod 333 is arranged parallel to the support rod 331. The driven rod 333 is rotatably connected to a connecting rod 3331, and the end of the connecting rod 3331 away from the driven rod 333 is rotatably connected to the support rod 331, and the connecting rod 3331 is parallel to the mounting rod 33. The driven rod 333 is rotatably connected to a driven post 3332. The support bar 42 has a driven groove along its length, and the driven groove coincides with the mating groove 421. There are two driven posts 3332, and both driven posts 3332 are located within the mating groove 421. When the support rod 331 rotates relative to the support block 5, the driven post 3332 can abut against the inner wall of the mating groove 421, so that the driven rod 333 can swing synchronously with the rotation of the support rod 331; the driven rod 333 provides support for the mounting rod 33, which helps to improve the stability of the movement of the mounting rod 33. In another embodiment, the driven groove can also be located above or below the mating groove 421, and the driven groove can also be formed on the guide plate 41; the number of driven posts 3332 can also be one, three or more.

[0057] Reference Figure 7 and Figure 8 In the initial state, the guide post 3321 is located at the bottom of the embedding groove 4131 (represented by the dashed line in the figure); at this time, the follower post 511 is located at the end of the follower groove 52 away from the guide post 3321, and the moving post 512 is located at the end of the moving groove 53 away from the guide post 3321. When the mounting rod 33 moves upward, the driving rod 332 (represented by a broken line in the figure) drives the guide post 3321 to slide upward along the embedding groove 4131, thereby driving the limiting post 3322 to move upward. At the same time, the support rod 331 (represented by a broken line in the figure) drives the follower post 511 and the moving post 512 to move towards the guide post 3321. When the follower post 511 moves into the extension groove 521, the follower post 511 can abut against the inner side wall of the lower side of the extension groove 521. At this time, the moving post 512 is aligned with the locking groove 531. When the guide post 3321 continues to move along the embedding groove 4131 towards the guide groove 413 (represented by a dashed line in the figure), the mounting rod 33 drives the support rod 331 to rotate around the follower post 511, so that the moving post 512 is embedded in the locking groove 531. At the same time, the end of the mounting rod 33 near the support rod 331 rises.

[0058] Reference Figure 7 and Figure 8As the guide post 3321 moves toward the guide groove 413, when the limiting post 3322 located near the guide post 3321 abuts against the inner wall of the upper side of the mating groove 421, the drive rod 332 rotates around the corresponding limiting post 3322 until the limiting post 3322 located away from the guide post 3321 abuts against the inner wall of the lower side of the mating groove 421. At this time, the end of the mounting rod 33 near the drive rod 332 rises. As the guide post 3321 continues to move, the drive rod 332 rotates and the limiting post 3322 slides along the inner wall of the mating groove 421, allowing the guide post 3321 to move into the guide groove 413. A limiting component 6 is provided between the support bar 42 and the support block 5 near the end of the embedding groove 4131. The limiting component 6 is used to fix the support block 5 in its initial position, allowing the support rod 331 to rotate relative to the support rod 331.

[0059] Reference Figure 8 and Figure 9 When the mounting rod 33 moves forward (X direction in the figure), the limiting post 3322 located near the guide post 3321 abuts against the inner wall of the upper side of the mating groove 421, and the limiting post 3322 located away from the guide post 3321 abuts against the inner wall of the lower side of the mating groove 421, thereby restricting the rotation of the drive rod 332 relative to the support bar 42, so that the guide post 3321 can move stably along the guide groove 413. During the forward movement of the mounting rod 33, the end of the support rod 331 near the mounting rod 33 is subjected to the force of the mounting rod 33, which causes the follower post 511 to abut against the inner wall of the extension groove 521 and the moving post 512 to abut against the inner wall of the locking groove 531, so that the support rod 331 can drive the support block 5 to move forward. A fixing component 7 is provided at the end of the support block 5 and the support bar 42 away from the insertion groove 4131. The structure of the fixing component 7 is the same as that of the limiting component 6. The fixing rod 61 of the fixing component 7 is fixedly installed on the end wall of the support block 5 away from the insertion groove 4131. The fixing component 7 fixes the support block 5 at the end of the support bar 42 away from the insertion groove 4131.

[0060] Reference Figure 8 and Figure 9 When the mounting rod 33 moves backward to reset until the support block 5 is fixed by the limiting component 6, the guide post 3321 is aligned with the embedding groove 4131. At this time, pressing down on the mounting rod 33 causes the end of the support rod 331 near the mounting rod 33 to move downward, thereby causing the end of the support rod 331 located on the moving post 512 to move upward along the inner wall of the locking groove 531 into the moving groove 53, so that the support rod 331 can move forward relative to the support block 5, thereby allowing the drive rod 332 to drive the guide post 3321 to move to the bottom of the embedding groove 4131, so that the mounting rod 33 returns to its initial position.

[0061] Reference Figure 10 The limiting component 6 includes a fixing rod 61, a limiting block 62, a fixing post 63, and an elastic fixing member 64. The fixing rod 61 is fixed to the end wall of the support block 5 near the guide post 3321 by screws. The bottom wall of the mating groove 421 has a mounting groove 4211. The limiting block 62 is embedded in the mounting groove 4211, and the side of the limiting block 62 facing away from the bottom wall of the mounting groove 4211 protrudes from the bottom wall of the mating groove 421 to abut against the end wall of the support block 5, thereby restricting the movement of the support block 5 towards the guide post 3321, so as to facilitate the rotation of the support rod 331 relative to the support block 5.

[0062] Reference Figure 10 and Figure 11 The limiting block 62 has a clearance groove 621 extending through the length of the mating groove 421; the fixing rod 61 is inserted into the clearance groove 621. Sliding holes 6211 are formed on the inner sidewalls of both sides of the clearance groove 621 along the width direction of the mating groove 421. Fixing grooves 611 are formed on the sidewalls of the fixing rod 61 facing each sliding hole 6211. Two sets of fixing posts 63 and elastic fasteners 64 are provided. One set of fixing posts 63 and corresponding elastic fasteners 64 is located in one sliding hole 6211, and the other set is located in the other sliding hole 6211. The fixing posts 63 can slide along the length of the sliding holes 6211, and the elastic fasteners 64 are located on the side of the corresponding fixing post 63 away from the clearance groove 621.

[0063] Reference Figure 10 and Figure 11 The elastic fastener 64 includes a spring; a screw cap 622 is threadedly connected to the inner wall of the sliding hole 6211 at the end away from the relief groove 621. One end of the elastic fastener 64 abuts against the screw cap 622, and the other end abuts against the corresponding fixing post 63, so that one end of the corresponding fixing post 63 is inserted into the corresponding fixing groove 611, thereby restricting the movement of the fixing rod 61 and the support block 5. In another embodiment, the sliding hole 6211 may also be formed along the width direction of the mating groove 421 on the inner wall of the mating groove 421 or along the depth direction of the mating groove 421 on the bottom wall of the mating groove 421; the fixing groove 611 may also be directly formed on the support block 5.

[0064] Reference Figure 11The fixing groove 611 is an arc-shaped groove; the fixing post 63 is spherical, thus forming an inclined guide surface 631, i.e., a spherical surface, on the end wall of the fixing post 63 near the fixing groove 611. The guide surface 631 abuts against the inner wall of the arc-shaped groove; when the support block 5 is subjected to a force away from the direction of the limiting block 62, the fixing rod 61 can move with the support block 5, and the fixing post 63 can automatically disengage from the fixing groove 611, making the operation convenient and labor-saving. When the fixing rod 61 moves out of the relief groove 621, the two fixing posts 63 abut against each other to reduce the possibility of the fixing post 63 falling out of the sliding hole 6211. In another embodiment, the fixing post 63 can also be cylindrical, and the corresponding guide surface 631 is formed on the end wall of the fixing post 63 near the relief groove 621; the guide surface 631 can be an arc-shaped surface or an inclined plane.

[0065] Reference Figure 10 and Figure 11 An elastic damping element 54 is provided between the support block 5 and the inner wall of the mating groove 421. The elastic damping element 54 includes an elastic sheet; the elastic damping element 54 is fixed to the side wall of the support block 5 by screws, and the side wall of the elastic damping element 54 facing away from the support block 5 abuts against the inner wall of the mating groove 421 to increase the friction between the support block 5 and the inner wall of the mating groove 421, so as to facilitate the relative fixation between the support block 5 and the inner wall of the mating groove 421. In another embodiment, the elastic damping element 54 may also include a rubber pad or other elastic structural components.

[0066] Reference Figure 10 and Figure 11 An arc-shaped spring plate 3311 is provided on the lower side wall of the support rod 331, located below the moving column 512. One end of the arc-shaped spring plate 3311 is fixed to the support rod 331 by a screw, and the other end abuts against the lower side wall of the support rod 331. When the moving column 512 is located in the locking groove 531, the arc-shaped spring plate 3311 abuts against the upper surface of the lower position of the support bar 42. At this time, the arc-shaped spring plate 3311 undergoes elastic deformation, exerting an upward force on the support rod 331, so that the moving column 512 abuts against the upper inner side wall of the locking groove 531, improving the stability of the engagement between the moving column 512 and the locking groove 531, and reducing the risk of the moving column 512 disengaging from the locking groove 531 during the movement of the support block 5 by the support rod 331. On the other hand, when the support rod 331 rotates upward at one end of the moving column 512, the arc-shaped spring plate 3311 can push the support rod 331 upward so that the moving column 512 can move from the locking groove 531 into the moving groove 53.

[0067] Reference Figure 11 and Figure 12A mounting block 55 is provided at the position of the locking groove 531 on the support block 5, and the mounting block 55 is fixed to the support block 5 with screws. The mounting block 55 is integrally formed with a sliding rod 551, the length direction of the sliding rod 551 is set along the length direction of the moving groove 53, and the sliding rod 551 is located on the side of the locking groove 531 away from the moving groove 53. An abutment post 5511 is sleeved on the end of the sliding rod 551 near the locking groove 531, and the abutment post 5511 can slide relative to the sliding rod 551. An elastic abutment member 5512 is connected to the abutment post 5511, and the elastic abutment member 5512 includes a spring; the elastic abutment member 5512 is located at the end of the abutment post 5511 away from the locking groove 531; the elastic abutment member 5512 is sleeved on the sliding rod 551, and one end of the elastic abutment member 5512 abuts against the abutment post 5511, and the other end abuts against the support block 5. The elastic abutment 5512 is in a compressed state so that the abutment post 5511 and the side wall of the movable post 512 away from the bottom wall of the locking groove 531 are pressed together, which further helps to reduce the risk of the movable post 512 disengaging from the locking groove 531.

[0068] Reference Figure 10 and Figure 13 A connecting block 56 is fixedly mounted on the support block 5 by screws, and the connecting block 56 is located above the locking groove. A guide hole 561 is formed on the side wall of the connecting block 56 facing the locking groove 531, and the guide hole 561 is formed along the length of the locking groove 531. A push rod 5611 is slidably connected to the inner side wall of the guide hole 561. An elastic push member 5612, including a spring, is connected to the end of the push rod 5611 away from the locking groove 531. One end of the elastic push member 5612 abuts against the end wall of the push rod 5611, and the other end abuts against the inner side wall of the guide hole 561, so that the end wall of the push rod near the locking groove 531 abuts against the support rod 331, thereby further fixing the support rod 331 and the moving post 512. In another embodiment, the end wall of the push rod 5611 near the locking groove 531 may also abut against the moving post 512.

[0069] Reference Figure 14 and Figure 15 A cleaning scraper 8 is provided at one end of the mounting bracket 31 near the open mating part 412. The cleaning scraper 8 includes a rotating plate 81 and a scraper strip 82. The length direction of the rotating plate 81 is arranged along the width direction of the mounting bracket 31; one side of the rotating plate 81 along its own width direction is rotatably connected to the lower surface of the mounting bracket 31 by a pin; the side of the rotating plate 81 away from the mounting bracket 31 is inclined towards the open mating part 412. A limit strip 311 is welded and fixed to the mounting bracket 31 at the position of the rotating plate 81 away from the open mating part 412. The limit strip 311 is used to support the rotating plate 81 so that the rotating plate 81 is kept in an inclined state.

[0070] Reference Figure 14 and Figure 15 The rotating plate 81 has a snap-fit ​​groove 811 on its side wall opposite to the mounting bracket 31, and the snap-fit ​​groove 811 extends through the rotating plate 81 along its length. The scraper 82 is a rubber strip, with one side of the scraper 82 along its width direction embedded in the snap-fit ​​groove 811, and the other side of the scraper 82 inclined towards the open mating part 412. When the mounting bracket 31 is raised and moves towards the open mating part 412, the lower side wall of the scraper 82 can abut against the upper surface of the roof 141 of the vehicle body to scrape away the dust deposited on the roof 141, thereby cleaning the roof 141 and the sunroof on the roof 141.

[0071] The implementation principle of this application embodiment is as follows:

[0072] When the rear cover 3 needs to be opened, pull the rear cover 3 upwards to move the guide post 3321 from the mounting groove 4131 to the guide groove 413, at which point the rear cover 3 rises; then push the rear cover 3 forward to move it to a position above the roof 141 of the vehicle body. Similarly, when the rear cover 3 needs to be closed, pull the rear cover 3 backwards to move the guide post 3321 along the guide groove 413 to the mounting groove 4131; then press the rear cover 3 downwards to move the guide post 3321 into the mounting groove 4131, and at the same time, the rear cover 3 lowers to close the opening of the vehicle's trunk 2.

[0073] During the opening or closing process, the rear cover 3 is always in a nearly horizontal state, which helps to reduce the possibility of the rear cover 3 increasing its windward area, thus making it easier to open or close the rear cover 3 in windy environments.

[0074] In another embodiment, the guide post 3321 and the limiting post 3322 may also be welded to the drive rod 332, integrally formed, or otherwise fixedly connected; the follower post 511 and the moving post 512 may also be welded to the support rod 331, integrally formed, or otherwise fixedly connected; the driven post 3332 may also be welded to the driven rod 333, integrally formed, or otherwise fixedly connected.

[0075] In another embodiment, the mounting bracket 31 may be equipped with a lock to secure the mounting bracket 31 to the vehicle body, thereby improving the stability of the windshield 32 in its initial closed state. The structure of the lock may refer to a vehicle trunk lock (also known as a trunk 2 lock) or an engine hood lock, which will not be described in detail here.

[0076] In this embodiment, the mounting rod 33 can be moved by moving the mounting bracket 31 or the wind deflector 32.
