[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, "several" refers to one or more, and "multiple" refers to two or more. The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] In the description of this utility model, the directions of up, down, front, back, left, and right refer to the position of the car in the vehicle's O-XYZ coordinate system. The origin O coincides with the center of mass of the vehicle. The front end refers to the X direction parallel to the ground pointing forward, the rear end refers to the X direction parallel to the ground pointing backward, the left side refers to the Y direction parallel to the ground pointing to the driver's left, the right side refers to the Y direction parallel to the ground pointing to the driver's right, the upper end refers to the Z direction passing through point O pointing upward, and the lower end refers to the Z direction passing through point O pointing downward.

[0027] It should be noted that with the increasing demand for spacious vehicles, the design size of vehicle trunks has further increased. However, the width of the trunk is limited by the width of the vehicle body, so the increase is limited. Therefore, the trunk size is mainly increased along the length of the vehicle body, resulting in an increased trunk depth. When users place suitcases or other items deep in the trunk, it is difficult for them to retrieve these items smoothly, reducing the user experience. The depth direction refers to the direction from the trunk door into the trunk; the depth dimension is the size of the trunk along this direction. The trunk door generally opens in the front-to-back direction of the vehicle, so the depth direction is from rear to front. Furthermore, when the trunk door opens to the right of the vehicle, the depth direction is from right to left; when the trunk door opens to the left of the vehicle, the depth direction is from left to right, such as in the trunk of a passenger vehicle.

[0028] Reference Figures 1 to 5 As shown, the first aspect of this utility model provides a trunk cover device, which is generally used as the bottom plate of the trunk (e.g., the trunk) of a vehicle and mainly serves to support heavy objects.

[0029] The trunk lid device includes a guide assembly 100, a cover 200, a rotation limiting assembly 300, and an unlocking assembly 400. The guide assembly 100 extends along the depth direction, allowing the cover 200 to move along the depth direction of the trunk via the guide assembly 100, enabling the cover 200 to move between the trunk door and a location away from the trunk door. The rotation limiting assembly 300 restricts the movement of the cover 200. The unlocking assembly 400 is connected to the rotation limiting assembly 300 and controls the rotation limiting assembly 300 to release its restriction on the cover 200, allowing the cover 200 to move along the depth direction. Therefore, when using the trunk lid device, the user first uses the unlocking assembly 400 to release the rotation limiting assembly 300 from the cover 200, and then pulls the cover 200 along the depth direction of the trunk to move the cover 200 to the trunk door or a location further away from the trunk door, making it easier for the user to retrieve or place objects on the cover 200.

[0030] The guide assembly 100 includes a guide rail 110 extending along the depth direction of the trunk and a sliding wheel 120 disposed on the guide rail 110. The sliding wheel 120 rolls with the guide rail 110, allowing the sliding wheel 120 to move along the guide rail 110. The guide rail 110 is fixed to the bottom of the bottom wall or side wall inside the trunk and extends along the depth direction of the trunk. The cross-sectional shape of the guide rail 110 can be various, such as U-shaped, C-shaped, or groove-shaped, to accommodate the sliding wheel 120 and guide its movement. In this embodiment, the guide assembly 100 includes two parallel guide rails 110, which are respectively disposed on both sides of the cover plate 200 to support and guide both sides of the cover plate 200, making the sliding of the cover plate 200 more convenient. In other embodiments, the guide rail 110 assembly includes three or more guide rails 110, all of which are arranged along the depth direction of the trunk and are arranged in parallel. Each guide rail 110 has at least one sliding wheel 120, for example, each guide rail 110 has three sliding wheels 120, and all three sliding wheels 120 are connected to the cover plate 200.

[0031] The cover plate 200 is connected to the sliding wheel 120, allowing it to move relative to the guide rail 110 along the depth direction of the trunk via the sliding wheel 120. The cover plate 200 is located on the bottom wall inside the trunk. Items such as suitcases can be placed on the upper surface of the cover plate 200, so that the cover plate 200 and the suitcase placed on the cover plate 200 move together along the depth direction of the trunk. In this embodiment, the upper surface of the cover plate 200 has an anti-slip layer, making the placement of items more stable; the lower surface of the cover plate 200 has a reinforcing structure, such as reinforcing ribs, to increase the overall structural strength of the cover plate 200.

[0032] The rotation limiting assembly 300 includes an elastic element 310 and a rotation limiting element 320. The elastic element 310 abuts against the rotation limiting element 320. The rotation limiting element 320 has a rotation limiting portion 321, which has a first position and a second position. In the first position, the rotation limiting portion 321 is abutted against the sliding wheel 120 by the elastic force of the elastic element 310, thus limiting the rotation of the sliding wheel 120. In the second position, the rotation limiting portion 321 is separated from the sliding wheel 120, allowing the sliding wheel 120 to move along the guide rail 110. When the rotation limiting portion 321 is in the first position, the elastic element 310 has a certain elastic potential energy, meaning that the elastic element 310 is in a pre-compressed or pre-stretched state.

[0033] In this embodiment, when the rotation limiting part 321 is in the first position, the elastic member 310 is in a pre-compressed state and is located on the side of the rotation limiting part 321 away from the sliding wheel 120. The elastic member 310, the rotation limiting part 321 and the sliding wheel 120 abut against each other in sequence. The rotation limiting part 321 abuts against the sliding wheel 120 under the elastic force of the elastic member 310. The friction between the rotation limiting part 321 and the sliding wheel 120 increases, thereby limiting the rotation of the sliding wheel 120. When the user applies an external force and the rotation limiting part 321 switches to the second position, the rotation limiting part 321 moves away from the sliding wheel 120, so that the sliding wheel 120 is no longer squeezed by the rotation limiting part 321, thereby releasing the restriction on the sliding wheel 120 and allowing the sliding wheel 120 to move along the guide rail 110. When the rotation limiting part 321 moves away from the sliding wheel 120, the elastic element 310 is further compressed, and the elastic force increases; when the external force applied by the user is removed, the rotation limiting part 321 is driven to return to the first position under the restoring force of the elastic element 310, thereby locking the sliding wheel 120.

[0034] An unlocking component 400 is disposed on the cover plate 200. The unlocking component 400 has a movable control member 410, which has a first state and a second state. The control member 410 can be operably switched from the first state to the second state. When the control member 410 is in the first state, the rotation limiter 320 is in the first position; when the control member 410 is in the second state, the rotation limiter 320 is in the second position. In this embodiment, the control member 410 can be operably rotated to switch between the first and second states. The user can drive the control member 410 to switch from the first state to the second state by rotating it, thereby causing the rotation limiter 320 to switch from the first position to the second position. For example, in the first state, the control member 410 is flush with the upper surface of the cover plate 200; in the second state, the control member 410 is angled to the upper surface of the cover plate 200. In another implementation, the control element 410 switches between a first state and a second state by translating. The user can drive the control element 410 from the first state to the second state by pressing it, thereby causing the rotation limiting element 320 to switch from the first position to the second position. The control element 410 can be mechanically connected to the rotation limiting element 320 or electrically connected to it. For example, the rotation limiting assembly 300 includes an electric telescopic rod, and the control element 410 is electrically connected to the electric telescopic rod via wires. When the control element 410 is in the first state, the electric telescopic rod extends, and the rotation limiting element 320 is in the first position. When the control element 410 is in the second state, the electric telescopic rod retracts, causing the rotation limiting element 320 to switch from the first position to the second position.

[0035] It is understandable that when a user needs to store items deep in the trunk, firstly, the user operates the control unit 410 to switch from the first state to the second state, the rotation limiter 321 will be in the second position, the sliding wheel 120 will be unlocked, and the cover 200 can move along the depth direction of the trunk; then, the user pulls the cover 200 to the trunk door, the user releases the control unit 410, the control unit 410 automatically resets to the first state under the drive of the elastic member 310, the rotation limiter 321 resets to the first position, the sliding wheel 120 is locked, the cover 200 is restricted from moving, and the user can place items on the cover 200; finally, the user operates the control unit 410 to switch to the second state and pushes the cover 200 to move deep into the trunk, so that the user can conveniently place items deep into the trunk, improving the user's comfort. When a user needs to retrieve items from deep within the trunk, firstly, the user operates the control unit 410 to switch from the first state to the second state, causing the rotation limiter 321 to be in the second position, the sliding wheel 120 to unlock, and the cover 200 to move along the guide rail 110. Then, the user applies external force along the depth direction of the trunk, causing the cover 200 to move from deep within the trunk to the trunk door, making it easier for the user to retrieve items from the cover 200. This makes it more convenient for the user to retrieve and place items, improving the user's comfort.

[0036] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the guide rail 110 includes a rail body 111 and a first guide portion 112. The rail body 111 has a track groove 1111. The first guide portion 112 extends along the length direction of the track groove 1111 and is disposed on the inner wall of the track groove 1111. The sliding wheel 120 includes a wheel body 121 and a second guide portion 122 disposed circumferentially on the outer circumferential surface of the wheel body 121. The wheel body 121 is disposed in the track groove 1111. The second guide portion 122 is connected to the first guide portion 112. The first guide portion 112 and the second guide portion 122 restrict the wheel body 121 from moving axially along the wheel body 121.

[0037] When the trunk cover device is installed inside the trunk, the track groove 1111 is set along the depth direction of the trunk, that is, the length direction of the track groove 1111 is in the same direction as the depth direction of the trunk.

[0038] In this embodiment, the guide assembly 100 includes two parallel guide rails 110, which are respectively located on both sides of the cover plate 200. The side of the rail body 111 opposite to the cover plate 200 has a track groove 1111. Each track body 111 has two first guide portions 112 within its track groove 1111. The two first guide portions 112 are respectively located on the top and bottom walls of the track groove 1111. The top and bottom of the second guide portion 122 on the outer periphery of the wheel body 121 are respectively connected to the two first guide portions 112, so that the sliding wheel 120 moves along the guide rails 110 in the depth direction of the trunk. In other words, the first guide portions 112 and the second guide portions 122 restrict the movement of the sliding wheel 120. The object moves left and right along the axis of the sliding wheel 120. When the rotation limiting member 320 abuts against one end of the wheel body 121 along the axis of the wheel body 121, the rotation limiting member 320 will push the wheel body 121 to move along the axis of the wheel body 121. At the same time, the first guide part 112 and the second guide part 122 restrict the wheel body 121 from moving along the axis of the wheel body 121. The rotation limiting member 320, the first guide part 112 and the second guide part 122 abut against each other, and the pressure between the three increases, thereby increasing the friction between the wheel body 121 and the rotation limiting member 320, and between the first guide part 112 and the second guide part 122. The wheel body 121 is subject to frictional resistance and is difficult to rotate, so that the object can be stably placed on the cover plate 200. In some embodiments, when the track groove 1111 includes a sidewall, the sidewall has an opening for the sliding wheel 120 to connect with the cover plate 200; when the track groove 1111 does not include a sidewall, the space between the top wall and the bottom wall directly connects the sliding wheel 120 with the cover plate 200. In other embodiments, each track body 111 includes one or more first guide portions 112. The track groove 1111 includes a bottom wall and two opposing sidewalls, which are located on opposite sides of the bottom wall and extend along the depth direction. The first guide portion 112 is located on the bottom wall, and the sliding wheel 120 connects to the cover plate 200 through the space above the sidewall.

[0039] Reference Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, one of the first guide portion 112 and the second guide portion 122 includes a guide protrusion, and the other of the first guide portion 112 and the second guide portion 122 includes a guide groove for the guide protrusion to be inserted.

[0040] Specifically, the first guide portion 112 is a guide protrusion, which is linearly distributed along the length of the track groove 1111, and the second guide portion 122 is a guide groove, which is annularly distributed along the circumference of the wheel body 121; or the first guide portion 112 is a guide groove, which is linearly distributed along the length of the track groove 1111, and the second guide portion 122 is a guide protrusion, which is annularly distributed along the circumference of the wheel body 121; the guide protrusion is embedded in the guide groove and plays a guiding role. The cross-sectional shapes of the guide protrusion and the guide groove are matched, for example, the cross-sectional shape of the guide protrusion is tangent to a circle, and the cross-sectional shape of the guide groove is also tangent to a circle.

[0041] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, when the rotation limiting part 321 is in the first position, the elastic member 310, the rotation limiting part 321, and the sliding wheel 120 abut against each other sequentially along the axial direction of the sliding wheel 120. In this embodiment, the elastic member 310 is in a pre-compressed state, thereby providing the rotation limiting part 321 with an elastic force toward the sliding wheel 120, so that the rotation limiting part 321 can abut against the end face of the sliding wheel 120, the pressure between the rotation limiting part 321 and the sliding wheel 120 increases, and the frictional resistance between the rotation limiting part 321 and the sliding wheel 120 further increases, so that the sliding wheel 120 is locked, and the cover plate 200 is difficult to move along the guide rail 110 via the sliding wheel 120.

[0042] Reference Figure 1 , Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the cover plate 200 includes a cover plate body 210 and a rotating shaft 220. One end of the rotating shaft 220 passes through the sliding wheel 120 and is coaxially arranged with the sliding wheel 120 so that the sliding wheel 120 can rotate around the rotating shaft 220. The other end of the rotating shaft 220 is fixed to the cover plate body 210. The rotating shaft 220 includes a main shaft portion 221 and a supporting portion 222 provided on the outer periphery of the main shaft portion 221. The supporting portion 222 is opposite to and spaced apart from the sliding wheel 120 along the axial direction of the sliding wheel 120. The rotation limiting portion 321 is located on the side of the sliding wheel 120 near the supporting portion 222. One end of the elastic member 310 abuts against the supporting portion 222, and the other end abuts against the rotation limiting portion 321.

[0043] In this embodiment, the cover plate body 210 is used to support heavy objects. The rotating shaft 220 is rotatably connected to the sliding wheel 120 through the main shaft portion 221, and can also restrict the end of the elastic member 310 away from the sliding wheel 120 through the abutment portion 222, so that the elastic member 310 can maintain a pre-compressed state or be further compressed. Specifically, the main shaft portion 221 is cylindrical, the sliding wheel 120 has a sliding through hole, the main shaft portion 221 passes through the sliding through hole, and the outer peripheral surface of the main shaft portion 221 slides in cooperation with the inner peripheral surface of the sliding through hole. The abutment portion 222 can be annularly coaxially disposed on the outer peripheral surface of the main shaft portion 221, or it can be block-shaped and protruding on the outer peripheral surface of the main shaft portion 221.

[0044] Reference Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the supporting part 222 surrounds the main shaft part 221 circumferentially. The main shaft part 221 has a first circumferential surface 2211, the supporting part 222 has a second circumferential surface 2221 and a stepped surface 2222 connecting the first circumferential surface 2211 and the second circumferential surface 2221. The stepped surface 2222 is opposite to and spaced apart from the end face of the sliding wheel 120. One end of the elastic member 310 abuts against the stepped surface 2222, and the other end abuts against the rotation limiting part 321.

[0045] In this embodiment, the supporting portion 222 surrounds the main shaft portion 221 to form an annular stepped surface 2222. The annular stepped surface 2222 supports the end face of the elastic member 310 and makes the end face of the elastic member 310 uniformly stressed, so as to facilitate the deformation of the elastic member 310. In addition, the rotating shaft 220 can also be interference-fitted to the cover plate body 210 through the outer peripheral surface of the annular supporting portion 222. Specifically, the side of the cover plate body 210 has a mounting groove, the supporting portion 222 is inserted into the mounting groove and interference-fitted with the mounting groove of the cover plate body 210 to realize the connection between the rotating shaft 220 and the cover plate body 210. In another embodiment, the rotating shaft 220 also includes a mounting part, which is connected to the cover plate body 210. The mounting part may be a first connecting hole provided on the outer peripheral surface of the main shaft part 221. The cover plate body 210 has a second connecting hole. After the first connecting hole and the second connecting hole are aligned, a fastener is inserted into the first connecting hole and the second connecting hole to achieve locking. For example, the fastener is a bolt, the first connecting hole has threads, and the fastener and the first connecting hole are locked by threads.

[0046] Reference Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the rotation limiting member 320 further includes a connecting part 322 and a transmission part 323. The transmission part 323 is disposed on the side of the abutting part 222 away from the sliding wheel 120 and is connected to the unlocking component 400. One end of the connecting part 322 is connected to the rotation limiting part 321, and the other end is connected to the transmission part 323.

[0047] It is worth understanding that the transmission part 323 is connected to the abutment part 222 through the connecting part 322 to avoid the rotating shaft 220, so that the transmission part 323 has sufficient space to be connected to the unlocking component 400, so that the unlocking component 400 and the rotating shaft 220 do not interfere with each other, and the structural layout is more reasonable. In this embodiment, the rotating shaft 220 is connected to the mounting groove of the cover plate body 210 through the abutment part 222. The connecting part 322 passes through the abutment part 222 along the axial direction of the sliding wheel 120 in the mounting groove. When the rotation limiting member 320 moves along the axial direction of the sliding wheel 120, the connecting part 322 moves relative to the abutment part 222 along the axial direction of the sliding wheel 120 through the mounting groove.

[0048] Reference Figure 3 and Figure 4 As shown, in some specific embodiments of this utility model, the elastic member 310 is sleeved on the main shaft portion 221, and the elastic member 310 can elastically deform along the axial direction of the sliding wheel 120. The rotation limiting portion 321 is sleeved on the main shaft portion 221, and the rotation limiting portion 321 can change relative to the sliding wheel 120 in a first position and a second position along the axial direction of the sliding wheel 120.

[0049] In this embodiment, the elastic element 310 is sleeved on the main shaft portion 221, and the rotation limiting portion 321 is sleeved on the main shaft portion 221. This allows the rotation limiting portion 321 to be guided by the main shaft portion 221 to move away from or towards the sliding wheel 120 along the axial direction of the rotating shaft 220, making the movement of the rotation limiting portion 321 more stable. At the same time, the force between the elastic element 310 and the rotation limiting portion 321 is uniform, which is more conducive to the stable deformation of the elastic element 310 along the axial direction of the rotating shaft 220, thus improving the reliability of use. As another embodiment, the rotation limiting portion 321 is arranged parallel to the main shaft portion 221 along the axial direction of the sliding wheel 120; the elastic element 310 is arranged parallel to the main shaft portion 221 along the axial direction of the sliding wheel 120. Alternatively, multiple elastic elements 310 are arranged parallel to the main shaft portion 221 along the axial direction of the sliding wheel 120, and the multiple elastic elements 310 surround the main shaft portion 221 circumferentially.

[0050] Specifically, the rotation limiting part 321 is circular and has a circular guide hole that guides and engages with the main shaft part 221; alternatively, the rotation limiting part 321 is rectangular, triangular, or other shapes and has a circular guide hole that guides and engages with the main shaft part 221. The elastic element 310 is a compression spring, which can be cylindrical or rectangular.

[0051] In some specific embodiments of this utility model, the unlocking component further includes a transmission component 420, a control component 410 rotatably connected to the cover plate 200, one end of the transmission component 420 being connected to the control component 410, and the other end being connected to the rotation limiting component 320. The control component 410 can switch between a first state and a second state by rotating relative to the cover plate 200, and control the rotation limiting part 321 on the rotation limiting component 320 to change between a first position and a second position.

[0052] It is worth understanding that the control component 410 is directly rotatably connected to the cover plate 200. The user can switch the control component 410 from the first state to the second state by operating the control component 410 to rotate relative to the cover plate 200, which improves the user's convenience. In this embodiment, the transmission component 420 is a pull cable. The control component 410 includes a handle part 411, a rotating shaft part 412, and a control part 413. The handle part 411 is rotatably connected to the cover plate 200 through the rotating shaft part 412, making it easier for the user to rotate. The control part 413 is directly connected to the outer periphery of the rotating shaft part 412. The pull cable is connected to the control part 413. When the handle part 411 rotates and drives the rotating shaft part 412 to rotate, the control part 413 rotates around the axis of the rotating shaft part 412 by a certain amount, causing the pull cable to be displaced and pulling the rotation limiting part 321 away from the sliding wheel 120. At this time, the rotation limiting part 321 switches to the second position, thereby unlocking the sliding wheel 120.

[0053] Reference Figure 5 As shown, in some specific embodiments of this utility model, the unlocking component 400 includes a fixed base 430 and a transmission component 420. The fixed base 430 is connected to the cover plate 200, and the transmission component 420 is connected between the control component 410 and the rotation limit component 320. The control component is rotatably connected to the fixed base 430, and the control component 410 can switch between a first state and a second state by rotating relative to the fixed base 430.

[0054] In this embodiment, the fixing base 430 is fixedly connected to the cover plate 200, and the control component 410 is integrated with the fixing base 430, making the assembly of the unlocking component 400 and the cover plate 200 more convenient. Specifically, the surface of the fixing base 430 exposed to the outside is provided with a fixing groove, and the control component 410 is rotatably disposed within the fixing groove, so that the control component 410 can be hidden within the fixing groove, making the unlocking component 400 more aesthetically pleasing overall.

[0055] Furthermore, the control component 410 includes a handle portion 411, a rotating shaft portion 412, and a control portion 413. The handle portion 411 is rotatably connected to the fixed base 430 via the rotating shaft portion 412. The rotating shaft portion 412 includes an extension portion extending beyond the fixed base 430. The control portion 413 is connected to the extension portion and is connected to the transmission component 420 outside the fixed base 430. When the rotating shaft portion 412 rotates to the second state, the control portion 413 rotates around the rotating shaft portion 412 by a certain amplitude, the pull cable undergoes a certain displacement, and pulls the rotation limiting portion 321 away from the sliding wheel 120. The rotation limiting portion 321 is in the second position, thereby unlocking the sliding wheel 120.

[0056] In addition, the unlocking component 400 also includes a torsion spring, which is sleeved on the part of the rotating shaft 412 located within the fixed seat 430. When the user removes the external force, the control component 410 can automatically reset to the fixed groove through the torsion spring. That is, the control component 410 can automatically reset from the second state to the first state, and the handle 411 does not need to be manually reset by the user, making it more convenient to use.

[0057] For ease of understanding, the following illustrative description is provided in the specific usage scenario of the trunk cover device inside the trunk. The following content does not constitute a specific limitation on this utility model: When a user needs to place luggage deep into the trunk along its depth direction, the user first controls the control element 410, switching it from a first state to a second state. While maintaining the control element 410 in the second state, the user pulls the cover 200 in the opposite direction of depth to the trunk door position. Simultaneously, the user rotates the handle 411, causing the transmission element 420 to shift. The transmission element 420 pulls the rotation limiter 320 away from the sliding wheel 120, unlocking the sliding wheel 120. Specifically, the transmission element 420 pulls the transmission part 323, which, through the connecting part 322, drives the rotation limiter 321 away from the sliding wheel 120 along its axial direction, further compressing the elastic member 310 between the rotation limiter 321 and the abutment part 222.

[0058] Then, the user releases the control element 410, locks the cover plate 200 to the door position, and places the luggage on the cover plate 200; wherein, the rotation limiting element 320 moves along the axis of the sliding wheel 120 towards the sliding wheel 120 under the elastic action of the elastic element 310. When the elastic element 310 returns to the pre-compression state, the rotation limiting element 320 abuts against the sliding wheel 120, and continues to abut against the sliding wheel 120 through the elastic force of the elastic element 310 in the pre-compression state, so that the sliding wheel 120 is locked; the movement of the rotation limiting element 320 will drive the control element 410 to return from the second state to the first state through the transmission element 420. Specifically, the elastic element 310 drives the rotation limiting part 321 to move toward the sliding wheel 120 along the axial direction of the sliding wheel 120. The rotation limiting part 321 drives the transmission part 323 to move toward the sliding wheel 120 through the connecting part 322. The transmission part 323 pulls the control part 410 through the transmission element 420, so that the control part 410 is reset from the second state to the first state. Finally, the user controls the control unit 410 again to keep the control unit 410 in the second state. The user pushes the cover plate 200 along the depth direction from the door position to the depth of the trunk, so that the luggage can be placed deep in the trunk, making it more convenient for the user to use.

[0059] A second aspect of this utility model provides a vehicle, including a vehicle body and a trunk cover device as described in the first aspect. The vehicle body has a trunk with a depth direction. The trunk cover device is disposed inside the trunk, and a guide rail 110 is arranged along the depth direction of the trunk to allow the cover 200 to move along the depth direction of the trunk. It is understood that the vehicle uses the trunk cover device of the first aspect embodiment to improve the convenience of retrieving and placing items in the trunk, thereby improving user comfort.

[0060] For passenger cars, the depth of the trunk is generally in the longitudinal direction of the vehicle. In this embodiment, the vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large semi-trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.
