For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0061] In one embodiment of the present invention, a trunk lid is disclosed, such as Figure 1 As shown, it includes a cover body 1, a movable wheel set 2 and a pull rod 3. The cover body 1 is provided with an accommodating recess 10. The movable wheel set 2 and the pull rod 3 are respectively movably connected to the cover body 1;

[0062] The trunk cover includes an unfolded state and a stowed state;

[0063] When in the unfolded state, at least one of the movable wheel set 2 and the pull rod 3 is movably unfolded to outside the accommodating recess 10;

[0064] When in the storage state, the movable wheel set 2 and the pull rod 3 are both movably stored in the accommodating recess 10 .

[0065] Furthermore, the cover body 1 can be installed at the bottom of a trunk, so as to separate the toolbox and spare tire built into the car through the cover body 1. At the same time, the cover body 1 can also play a load-bearing role and be used to hold the passenger's belongings. Among them, the receiving recess 10 is provided on the downward side of the cover body 1, and the movable wheel set 2 and the pull rod 3 are both provided on the downward side of the cover body 1. When the cover body 1 is installed in the trunk, the movable wheel set 2 and the pull rod 3 can be hidden in the receiving recess 10, so as not to affect the matching installation of the lower surface of the cover body 1 with the trunk. At the same time, the movable wheel set 2 and the pull rod 3 are hidden below the cover body 1, so as not to affect the upper surface of the cover body 1 for holding objects.

[0066] Furthermore, Figure 1 and Figure 2 As shown, there are at least two sets of movable wheel groups 2, wherein at least two sets of movable wheel groups 2 are arranged on one side of the cover body 1. When the movable wheel group 2 is movable and unfolded to the receiving recess 10, the rotating axis of the movable wheel group 2 is movable to be parallel to the cover body 1. At this time, the movable wheel group 2 can be used to support the cover body 1, so that the cover body 1 can have a walking function. When the movable wheel group 2 is movable and stored in the receiving recess 10, the rotating axis of the movable wheel group 2 is movable to be perpendicular to the cover body 1. At this time, the movable wheel group 2 can be hidden in the receiving recess 10, reducing the space occupied by the movable wheel group 2. The pull rod 3 can be movably connected to the cover body 1. When the pull rod 3 is movably unfolded, the pull rod 3 can extend out of the outside of the cover body 1 along the length direction of the cover body 1, so as to facilitate the user to hold and drag. Alternatively, the pull rod 3 can be movable to be at least partially perpendicular to the cover body 1, so as to support the cover body 1 and place it on the ground, thereby playing the role of a table or stool.

[0067] The trunk cover in this application has an unfolded state and a stowed state, such as Figure 1 As shown, when the trunk cover needs to be placed in the trunk, the movable wheel set 2 and the pull rod 3 are both movably stored in the receiving recess 10, so that the trunk cover can remain flat and placed in the trunk to achieve the load-bearing function. Figure 3-Figure 5 As shown, when the trunk cover needs to be taken out for use, at least one of the movable wheel set 2 or the pull rod 3 is unfolded beyond the accommodating recess 10, so that the trunk cover has a walking function or a pulling function, so that the trunk cover can realize different functions and is suitable for use in different usage scenarios.

[0068] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, it also includes a fixing block 11 for cooperating with the tool box, the fixing block 11 is fixedly connected to the cover body 1, and an accommodating recess 10 is formed between the fixing block 11 and the cover body 1;

[0069] When the movable wheel set 2 and the pull rod 3 are received in the accommodating recess 10 , the movable wheel set 2 and the pull rod 3 are located between the cover body 1 and the surface of the fixing block 11 away from the cover body 1 .

[0070] Furthermore, the fixing block 11 is fixedly connected to the lower surface of the cover body 1, wherein the fixing block 11 is provided with a plurality of Figure 1 and Figure 2 As shown, the fixing block 11 includes a first fixing portion 111, a second fixing portion 112, and a third fixing portion 113. The second fixing portion 112 is disposed between the first fixing portion 111 and the third fixing portion 113. The movable wheel set 2 is movably connected between the first fixing portion 111 and the second fixing portion 112. The pull rod 3 is movably connected between the second fixing portion 112 and the third fixing portion 113. The first fixing portion 111, the second fixing portion 112, and the third fixing portion 113 enable the toolbox in the luggage compartment to be installed in conjunction with the toolbox. When in the stowed state, the movable wheel set 2 and the pull rod 3 are both movable into the receiving recess 10. At this time, the movable wheel set 2 and the pull rod 3 are both located between the side of the fixing plate away from the cover body 1 and the cover body 1. That is, the thickness of the movable wheel set 2 and the pull rod 3 when stowed is less than the thickness of the fixing block 11, thereby not affecting the mating installation of the cover body 1 and the toolbox, thereby reducing the space occupied by the luggage compartment cover.

[0071] In some embodiments of the present invention, Figure 6 As shown, the movable wheel group 2 includes a roller 21 and a bracket 22, the roller 21 is rotatably connected to the bracket 22, the bracket 22 is rotatably connected to the cover body 1, the sleeve 4 is connected between the bracket 22 and the pull rod 3, and the bracket 22 and the pull rod 3 are connected through the sleeve 4.

[0072] Further, such as Figure 6 As shown, the bracket 22 is rotatably connected to one side of the first fixing portion 111 via the rotating shaft 24. The bracket 22 can rotate around the axis of the rotating shaft 24 to achieve expansion or storage. Figure 7As shown, a limiting groove 1111 is provided on the side of the first fixing portion 111. A limiting post 221 is inserted into and slides within the limiting groove 1111. The limiting post 221 cooperates with the limiting groove 1111 to limit the rotation angle of the bracket 22. When in the stowed state, the bracket 22 rotates about the axis of the rotating shaft 24 until the roller 21 abuts the lower surface of the cover body 1. The movable wheel assembly 2 is now hidden within the receiving recess 10, and the limiting post 221 slides relative to the first end of the limiting groove 1111. When in the deployed state, the bracket 22 rotates about the axis of the rotating shaft 24 until the rotation axis of the roller 21 is parallel to the cover body 1. The roller 21 then flips out of the receiving recess 10, thereby supporting the cover body 1 and achieving the mobile function. At the same time, the limiting post slides relative to the second end of the limiting groove 1111, thereby preventing the bracket 22 from further flipping outward, ensuring that the movable wheel assembly 2 can remain deployed.

[0073] The thickness of the bracket 22 and the roller 21 is less than or equal to the thickness of the fixed block 11, so that when in the storage state, the movable wheel group 2 can be hidden in the accommodating recess 10 to avoid affecting the installation of the cover body 1 and the tool box.

[0074] In some embodiments of the present invention, Figure 6 As shown, a first elastic member 23 for driving the bracket 22 to unfold is provided between the bracket 22 and the cover body 1 .

[0075] Further, such as Figure 6 As shown, the first elastic member 23 is a tension spring, wherein one end of the tension spring is connected to the outer side of the bracket 22, and the other end is connected to the cover plate body. When unfolded, the elastic force of the tension spring can make the bracket 22 flip outward around the axis of the rotating shaft 24 until the limiting column 221 moves relative to the second end of the limiting groove 1111, so that the movable wheel group 2 is in the unfolded state. At the same time, under the action of the tension spring, the movable wheel group 2 can be kept unfolded, which can prevent the movable wheel group 2 from flipping inward during use, thereby improving the stability of use.

[0076] In some embodiments of the present invention, Figure 2 As shown, the pull rod 3 includes an inner rod 31 and an outer rod 32. The outer rod 32 is sleeved on the inner rod 31. The outer rod 32 is fixedly connected to the cover body 1. The inner rod 31 can slide relatively along the axial direction of the outer rod 32 and rotate relative to the outer rod 32.

[0077] Further, such as Figure 1 and Figure 2 As shown, the outer rod 32 is fixedly connected between the second fixing portion 112 and the third fixing portion 113, wherein the outer rod 32 is a hollow structure, the outer rod 32 is sleeved on the inner rod 31, and the inner rod 31 can slide relatively along the axial direction of the outer rod 32 and rotate around the axis of the outer rod 32.

[0078] When stowed, the inner rod 31 is retracted into the outer rod 32, thereby reducing the space occupied by the trunk cover and ensuring that the cover body 1 can be properly installed with the tool box. When unfolded, the inner rod 31 is moved so that it extends out of the cover body 1 along the axial direction of the outer rod 32, making it easier for the user to drag and use the trunk cover.

[0079] In some embodiments of the present invention, Figure 2 As shown, the end of the pull rod 3 is detachably connected to the support accessory 34 , and the support accessory 34 is a movable wheel set 2 or a handle 341 .

[0080] Furthermore, the support accessory 34 is detachably connected to the end of the inner rod 31, and the support accessory 34 can be replaced according to the use requirements. When the support accessory 34 is a handle 341, when the handle 341 is stored, the inner rod 31 is rotated so that the handle 341 rotates parallel to the cover body 1, thereby allowing the handle 341 to be hidden in the receiving recess 10. When in use, Figure 5 As shown, the handle 341 can be rotated 90 degrees so that the handle 341 is perpendicular to the cover body 1, and the handle 341 cooperates with the movable wheel set 2 to support the cover body 1 and place it on the ground, so that the trunk cover can function as a table or stool. Figure 3 As shown, or by pulling the inner rod 31 out of the outer rod 32, the handle 341 can be conveniently held by the user, and the luggage compartment cover can be transformed into a pulling cart for use in conjunction with the movable wheel set 2. Figure 4 As shown, the support component 34 can also be a movable wheel set 2. By separating the handle 341 from the inner rod 31 and then connecting the movable wheel set 2 to the inner rod 31, the trunk lid can be transformed into a flatbed truck. By selecting different support components 34, the function of the trunk lid can be changed to adapt to different working conditions.

[0081] Furthermore, the handle 341 is wrapped with anti-slip rubber to facilitate the user's grip and use.

[0082] Specifically, the support fitting 34 and the end of the inner rod 31 are installed through threaded fitting, which can reduce the difficulty of disassembly and assembly and improve the convenience of use.

[0083] In addition, if Figure 3As shown, a stopper 16 is provided on the upper surface of the cover body 1, and a receiving opening is provided on the upper surface of the cover body 1. The stopper 16 is rotatably connected to the receiving opening. When the stopper 16 is not in use, the stopper 16 can be rotated and stored in the receiving opening, thereby maintaining the flatness of the upper surface of the cover body 1 and facilitating the storage of objects. When the trunk cover needs to be converted into a cart, the stopper 16 can be rotated out of the receiving opening to support objects placed on the upper surface of the cover body 1.

[0084] Alternatively, as Figure 3 As shown, the cover body 1 also includes a storage bag 15, the hook of which can be hung on the inner rod 31, thereby further improving the storage function. A magnetic element is provided on the storage bag 15. When the storage bag 15 is not in use, the magnetic element can be used to adsorb the storage bag 15 on the cover body 1, ensuring the surface flatness and cleanliness of the cover body 1.

[0085] Alternatively, as Figure 13 As shown, the storage rack 17 includes a first baffle 171, a second baffle 172, a support rod 173, and a side fence 174. One side of the first baffle 171 is hinged to the cover body 1, and the other side opposite the first baffle 171 is hinged to the second baffle 172. The second baffle 172 connects the first baffle 171 and the support rod 173. One end of the support rod 173 is hinged to the second baffle 172, and the other end is slidably connected to the guide groove on the cover body 1. The two ends of the side fence 174 are respectively hinged to the second baffle 172 and the cover body 1. When the storage rack 17 is not in use, the first baffle 171, the second baffle 172, and the support rod 173 are flipped over to fit the cover body 1 to ensure the surface flatness of the cover body 1. When in use, the support rod 173, the first baffle 171 and the second baffle 172 are rotated in a direction away from the cover body 1, so that the first baffle 171, the second baffle 172 and the side fence 174 are unfolded to form a box-shaped structure, which can be used to hold objects.

[0086] In some embodiments of the present invention, Figure 8 and Figure 9 As shown, a first locking assembly is provided between the outer rod 32 and the sleeve 4, and the first locking assembly includes a first elastic block 321 and a first limiting hole 41;

[0087] The first elastic block 321 is provided on one of the outer rod 32 or the sleeve 4, and the first limiting hole 41 is provided on the other one of the outer rod 32 or the sleeve 4;

[0088] When the first locking assembly is unlocked, the first elastic block 321 is disengaged from the first limiting hole 41, and the sleeve 4 can rotate relative to the outer rod 32;

[0089] When the first locking assembly is locked, the first elastic block 321 is locked into the first limiting hole 41 , and the sleeve 4 and the outer rod 32 are relatively fixed.

[0090] Further, such as Figure 8 As shown, a first bayonet 43 is provided along its axial direction at one end of the sleeve 4, the end of the outer rod 32 is inserted into the first bayonet 43, the first limiting hole 41 is provided on the circumferential side wall of the first bayonet 43, and the first elastic block 321 is provided on the circumferential side wall of the outer rod 32. When the movable wheel group 2 rotates to the expanded state, the first limiting block 12 moves relatively to the position of the first limiting hole 41 and is inserted into the first limiting hole 41, thereby limiting the relative rotation between the sleeve 4 and the outer rod 32, and further limiting the further flipping of the movable wheel group 2, so that the movable wheel group 2 can maintain the expanded state, thereby ensuring the stability of the movable wheel group 2 when in use.

[0091] In some embodiments of the present invention, Figure 8 and Figure 10 As shown, a second locking assembly is provided between the inner rod 31 and the sleeve 4, and the second locking assembly includes a second elastic block 311 and a second limiting hole 42;

[0092] The second elastic block 311 is provided on one of the inner rod 31 or the sleeve 4, and the second limiting hole 42 is provided on the other of the inner rod 31 or the sleeve 4;

[0093] When the second locking assembly is unlocked, the second elastic block 311 is disengaged from the second limiting hole 42, the inner rod 31 and the sleeve 4 can move relative to each other, and the inner rod 31 can slide along the axial direction of the outer rod 32;

[0094] When the second locking assembly is locked, the second elastic block 311 is locked into the second limiting hole 42 , and the inner rod 31 and the sleeve 4 are relatively fixed.

[0095] Further, such as Figure 8 As shown, the second limiting hole 42 is provided on the circumferential side wall of the first bayonet 43, and the second elastic block 311 is provided on the circumferential side wall of the inner rod 31. When the second elastic block 311 is inserted into the second limiting hole 42, the inner rod 31 can drive the sleeve 4 to rotate, thereby facilitating the user to control the rotation, deployment or folding of the movable wheel assembly 2. The second elastic block 311 is made of an elastic material, and the side of the second elastic block 311 facing the insertion / extraction of the first bayonet 43 is designed as an arc or inclined surface, thereby facilitating the disengagement of the second elastic block 311 from the second limiting hole 42. When the second elastic block 311 is disengaged from the second limiting hole 42, the inner rod 31 and the outer rod 32 can slide relative to each other, so that the inner rod 31 can extend outside the outer rod 32.

[0096] In addition, if Figure 11As shown, a second bayonet 45 is provided along its axial direction at the other end of the sleeve 4, and the rotating shaft 24 in the movable wheel group 2 is inserted into the second bayonet 45, and a boss 241 is provided at the end of the rotating shaft 24, and the boss 241 is rectangular or polygonal. Correspondingly, a slot 44 is provided in the second bayonet 45, and the boss 241 is inserted into the slot 44 so that the rotating shaft 24 and the sleeve 4 can rotate synchronously.

[0097] Furthermore, a plurality of locking holes are provided on the outer rod 32. By inserting a locking pin into the locking hole and connecting the inner rod 31, the relative rotation and relative sliding between the inner rod 31 and the outer rod 32 can be restricted, so that the inner rod 31 and the outer rod 32 can be maintained in the expanded state or the retracted state.

[0098] In some embodiments of the present invention, Figure 12 As shown, a third locking assembly is provided on the third fixing portion 113. The third locking assembly includes a limit block 12, a push button switch 13, and a second elastic member 14. The limit block 12 is slidably connected to the third fixing portion 113, the push button switch 13 is connected to the limit block 12, and the second elastic member 14 is connected between the limit block 12 and the third fixing portion 113. A limit hole 313 is provided on the inner rod 31. The limit block 12 extends through the outer rod 32 and can be snapped into the limit hole 313 on the inner rod 31. When the third locking assembly is unlocked, the user controls the limit block 12 to disengage the limit hole 313 via the push button switch 13, allowing the inner rod 31 to rotate and slide relative to the outer rod 32. When the third locking assembly is locked, the limit block 12 remains locked in the limit hole 313 under the elastic force of the second elastic member 14, so that the inner rod 31 and the outer rod 32 are relatively fixed. Since the inner rod 31 and the movable wheel group 2 are linked through the sleeve 4, when the third locking assembly is locked, the bracket 22 can also be restricted from rotating, so that the movable wheel group 2 remains expanded or retracted.

[0099] In some embodiments of the present invention, Figure 2 As shown, there are two groups of pull rods 3, which are arranged in parallel. A balance rod 33 is provided between the two groups of pull rods 3, and both ends of the balance rod 33 are connected to the two inner rods 31 respectively.

[0100] like Figure 9 As shown, the side wall of the outer rod 32 is provided with a first sliding hole 322 arranged along its axial direction. Figure 10 As shown, the side wall of the inner rod 31 is provided with a second sliding hole 312 arranged along its circumference, and the end of the balance rod 33 passes through the first sliding hole 322 and is movably connected to the second sliding hole 312.

[0101] Furthermore, the provision of the balancing rod 33 enhances the stability between the two sets of inner rods 31, preventing the inner rods 31 from wobble. The balancing rod 33 extends through the first sliding hole 322. When the inner rods 31 slide axially relative to the outer rods 32, the balancing rod 33 slides with the inner rods 31, preventing interference with the outer rods 32. Furthermore, because the ends of the balancing rod 33 are connected to the second sliding holes 312 circumferentially disposed along the inner rods 31, when the inner rods 31 rotate axially relative to the outer rods 32, the balancing rod 33 does not rotate with the inner rods 31, thus preventing interference.

[0102] The present application also discloses a car, comprising the above-mentioned trunk cover.

[0103] The above description is only the principle and preferred embodiment of the present application. It should be noted that, for those skilled in the art, on the basis of the principle of the present application, several other variations can be made, which should also be considered as the scope of protection of the present application.
