[0029] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0031] In related technologies, trunk carpets are installed inside the trunk, positioned below or flush with the rear sill to fit the overall layout of the trunk. However, trunk carpets are typically installed in a fixed manner, meaning their position is fixed. This design limits their use to a single scenario and makes it difficult to expand their application to other scenarios. To address these issues, this utility model proposes a trunk and vehicle. The trunk and vehicle mentioned above are described in detail below.

[0032] Firstly, referring to Figures 1 to 4 The trunk provided in this embodiment of the utility model includes a trunk carpet 1, a lifting mechanism 2 and a sliding mechanism 3. The sliding mechanism 3 includes a sliding member 32 that can slide along the front and rear direction of the trunk. The lifting mechanism 2 is located between the sliding member 32 and the trunk carpet 1. The trunk carpet 1 includes a metal frame, a foam layer and a surface layer. The foam layer is located between the metal frame and the surface layer. The foam layer covers the metal frame and the surface layer covers the foam layer.

[0033] The trunk is used in vehicles, which can be sedans, commercial vehicles, SUVs, SUVs, etc., and can be pure electric vehicles, gasoline vehicles, hybrid vehicles, etc. In the description of this utility model embodiment, the front-rear, up-down, and left-right positions are consistent with the front-rear, up-down, and left-right positions of the vehicle.

[0034] The lifting mechanism 2 is used to move the trunk carpet 1 up and down along the height of the trunk, thereby raising or lowering the trunk carpet 1. When the sliding member 32 slides along the front-to-back direction of the trunk, the lifting mechanism 2 and the trunk carpet 1 slide together with the sliding member 32. The sliding mechanism 3 is used to move the lifting mechanism 2 and the trunk carpet 1 along the front-to-back direction of the trunk, so that the trunk carpet 1 extends out of the vehicle or retracts into the vehicle. The front-to-back direction of the trunk can be referenced... Figure 1 and Figure 2 The direction indicated by arrow A in the middle.

[0035] The sliding mechanism 3 and the lifting mechanism 2 are arranged in the space between the trunk carpet 1 and the lower vehicle body sheet metal, that is, the sliding mechanism 3 and the lifting mechanism 2 are located below the trunk carpet 1 and above the lower vehicle body sheet metal. The sliding mechanism 3 may also include a slide rail 31, and the sliding element 32 is slidably connected to the slide rail 31 along the front-rear direction of the trunk. The lifting mechanism can be a screw lifting mechanism, a cylinder lifting mechanism, a gear and rack lifting mechanism, etc. The trunk carpet 1 has a three-layer structure consisting of a metal frame, a foam layer, and a surface layer. Preferably, the foam layer completely covers the metal frame, and preferably, the surface layer completely covers the foam layer. The metal frame can be made of steel, aluminum, etc., the foam layer can be made of polyurethane foam, ethylene-vinyl acetate foam, etc., and the surface layer can be made of needle-punched fabric.

[0036] The trunk carpet 1 has a first position located inside the trunk and a second position extending at least partially outside the trunk. (See reference...) Figure 2 Under normal circumstances, the trunk carpet 1 is in the first position, and it is either lower than or flush with the rear door sill. (Refer to...) Figure 4 In the second position, the trunk carpet 1 extends outside the trunk, meaning it extends outside the vehicle. In this position, the trunk carpet 1 can be used as a seat or a table for outdoor activities. The trunk door must be opened when switching between the first and second positions.

[0037] As an example, when the trunk carpet 1 moves from the first position to the second position, the lifting mechanism 2 operates first, causing the trunk carpet 1 to rise until it is higher than the back sill. The trunk carpet 1 then stops rising. After that, the sliding mechanism 3 operates, and the sliding member 32 slides toward the opening of the trunk, that is, slides backward, causing the lifting mechanism 2 and the trunk carpet 1 to slide backward until the trunk carpet 1 slides to the second position.

[0038] In this embodiment of the invention, the sliding mechanism 3 and the lifting mechanism 2 allow the trunk carpet 1 to be raised, lowered, and slid along the front-to-back direction of the trunk. This allows the trunk carpet 1, originally located inside the trunk, to extend outside the vehicle. The extended trunk carpet 1 can be used as a seat or a table, thus expanding its usability. Furthermore, the extended trunk carpet 1 makes it easier for users to retrieve items carried on it. Additionally, the metal frame within the trunk carpet 1 increases its strength, enabling it to bear greater weight and allowing for repeated use in scenarios such as seating and table applications. Moreover, the foam layer covering the metal frame and the surface layer further enhances user comfort when the trunk carpet 1 is used for seating.

[0039] In some embodiments, the metal frame includes a plate and a plurality of honeycomb holes formed on the plate. The plate is rectangular in shape. In this embodiment, by forming a plurality of honeycomb holes on the plate, the trunk carpet 1 is made lighter while ensuring its strength.

[0040] In other embodiments, the metal frame may include multiple metal rods connected together to form a frame structure, and the metal rods are hollow.

[0041] In some embodiments, the sliding mechanism 3 further includes a slide rail 31, and the sliding member 32 is slidably connected to the slide rail 31 in the front-rear direction of the trunk; the lifting mechanism 2 includes a housing and a lifting rod extending in the height direction of the trunk, the housing is connected to the sliding member 32, and the lifting rod is connected to the front end of the trunk carpet 1.

[0042] The slide rail 31 is mounted on the lower body sheet metal and extends along the front-rear direction of the trunk, located in front of the rear panel of the vehicle. The slide rail 31 has a groove 311, within which a sliding member 32 is slidably connected. The sliding mechanism 3 also includes a second lead screw and a second ball nut that cooperates with the lead screw. The second lead screw extends along the front-rear direction of the trunk; when the lead screw rotates, the second ball nut moves along the front-rear direction of the trunk, and the sliding member 32 is connected to the second ball nut. The sliding stroke of the sliding member 32 is limited by the length of the slide rail 31. For different vehicle models, the length of the slide rail 31 can be adjusted according to the front-rear dimensions of the trunk, thereby adjusting the sliding stroke of the sliding member 32 to adapt to different vehicle models.

[0043] When the lifting mechanism is a screw lifting mechanism, the lifting rod is the first screw; when the lifting mechanism is a cylinder lifting mechanism, the lifting rod is the piston rod of the cylinder; and when the lifting mechanism is a rack and pinion lifting mechanism, the lifting rod is the rack. The connection between the lifting rod and the trunk carpet 1 is detachable, such as by bolts or snap-fit. The connection between the housing and the sliding member 32 is also detachable, such as by bolts or snap-fit. The housing can be embedded within the sliding member 32. In this embodiment, after the trunk carpet 1 extends outside the vehicle, the front end of the trunk carpet 1 remains inside the vehicle. The lifting mechanism 2, connected to the front end of the trunk carpet 1, is located inside the vehicle and does not protrude outside, ensuring aesthetics.

[0044] In some embodiments, there are two sliding mechanisms 3, which are arranged at intervals along the left-right direction of the trunk; there are two lifting mechanisms 2, which are respectively connected to the sliding parts 32 of the two sliding mechanisms 3, and are respectively connected to both ends of the trunk carpet 1 along the left-right direction of the trunk. The left-right direction of the trunk can be referred to as... Figure 1 The direction indicated by arrow B. The two sliding mechanisms 3 can be arranged symmetrically. In this embodiment, the use of two sliding mechanisms 3 and two lifting mechanisms 2 can improve the sliding stability and lifting stability of the trunk carpet 1.

[0045] In some embodiments, the sliding mechanism 3 includes a first driving member 33, and the lifting mechanism 2 includes a second driving member. Both the first driving member 33 and the second driving member are connected to conductive wires. Along the left-right direction of the trunk, the conductive wires connected to the first driving member 33 and the second driving member on the same side are integrated into a first wire harness 6, and two first wire harnesses 6 are integrated into a second wire harness 7.

[0046] The first driving component 33 can be a first motor, which drives the second lead screw to rotate. By controlling the first motor, the sliding component 32 can be controlled to slide. The second driving component can be a second motor, which controls the lifting rod to rise and fall. The conductive wire connected to the first driving component 33 is a first conductive wire, which supplies power to the first driving component 33 and transmits signals to it. The conductive wire connected to the second driving component is a second conductive wire 5, which supplies power to the second driving component and transmits signals to it.

[0047] Figure 1 In this embodiment, the second conductive wire 5 connected to the second driving component on the left passes through the first driving component 33 on the left and is integrated with the first conductive wire connected to the first driving component 33 on the left to form a first wire harness 6. The second conductive wire 5 connected to the second driving component on the right passes through the first driving component 33 on the right and is integrated with the first conductive wire connected to the first driving component 33 on the right to form another first wire harness 6. The two first wire harnesses 6 can converge on the right side. It should be noted that the second conductive wire 5 located between the second driving component and the first driving component 33 has sufficient length to accommodate the sliding stroke of the slider 32. The second wire harness 7 can be wound along the lower body sheet metal to the side trim panel of the trunk. In this embodiment, the conductive wires connected to the first driving component 33 and the second driving component on the same side are integrated into a first wire harness 6, and the two first wire harnesses 6 are integrated into a second wire harness 7, which can optimize the wiring and improve the neatness of the wiring.

[0048] In some embodiments, the slide rails 31 of the two sliding mechanisms 3 are connected by at least one reinforcing member 4. The reinforcing member 4 extends along the left-right direction of the trunk, and the number of reinforcing members 4 can be one or more, for example, one, two, three, four, five, etc. When there are multiple reinforcing members 4, they are arranged at intervals along the front-rear direction of the trunk. The reinforcing member 4 can be made of steel. The reinforcing member 4 is preferably a hollow rod. In this embodiment, the connection between the two slide rails 31 via the reinforcing member 4 can improve the overall rigidity and stability of the two slide rails 31.

[0049] In some embodiments, the lifting mechanism 2 is a screw lifting mechanism, and the lifting rod is the first screw of the screw lifting mechanism.

[0050] The lifting mechanism 2 further includes a first ball nut that meshes with the first lead screw, a worm gear, and a worm that meshes with the worm gear. The worm gear is connected to the first ball nut, and both the worm gear and the first ball nut are housed within a housing. A second motor is connected to the worm. When the second motor is running, the worm rotates, driving the worm gear to rotate. The rotation of the worm gear drives the first ball nut to rotate, causing the first lead screw to rise or fall. The worm gear transmission has a self-locking property; when the second motor is not running, the first lead screw will not fall back on its own, ensuring that the trunk carpet 1 can be maintained at the target height. In this embodiment, the lead screw lifting mechanism has a small horizontal dimension, occupies less space, and is conducive to the arrangement of the lifting mechanism 2.

[0051] In some embodiments, a switch button is provided in the trunk, which is used to trigger the trunk carpet 1 to switch between a first position and a second position.

[0052] The switch button can be located on the side panel of the trunk, and can be integrated with the seat folding switch, trunk hook, etc. When the trunk carpet 1 is in the first position, pressing the switch button sends a first signal to the second conductive line 5. The second conductive line 5 transmits the first signal to the second motor, causing the second motor to rotate forward. After the second motor rotates forward, it drives the lifting rod to rise, which in turn raises the trunk carpet 1 until it is higher than the back sill. At this point, the second motor stops rotating, and the trunk carpet 1 stops rising. Then, the control system sends a second signal to the first conductive line, which transmits the second signal to the first motor, causing the first motor to rotate forward. After the first motor rotates forward, it drives the sliding member 32 to slide backward along the slide rail 31. The sliding member 32 slides backward, causing the lifting mechanism 2 and the trunk carpet 1 to slide backward synchronously until the trunk carpet 1 slides to the second position, at which point the first motor stops rotating.

[0053] When the trunk carpet 1 is in the second position, pressing the switch button sends a third signal from the control system to the first conductive line. The first conductive line transmits the third signal to the first motor, causing it to reverse. After the first motor reverses, it drives the sliding member 32 to slide forward along the slide rail 31. The sliding member 32's forward movement causes the lifting mechanism 2 and the trunk carpet 1 to slide forward synchronously until the trunk carpet 1 is inside the trunk. At this point, the first motor stops rotating, and the trunk carpet 1 stops sliding. Then, the control system sends a fourth signal to the second conductive line 5, which transmits the fourth signal to the second motor, causing it to reverse. After the second motor reverses, it drives the lifting rod to descend, causing the trunk carpet 1 to descend until it reaches the first position, at which point the second motor stops rotating. In this embodiment, the switch button located inside the trunk allows the user to easily switch the trunk carpet 1 between the first and second positions with a single button press.

[0054] In other embodiments, in addition to a switch button in the trunk, a soft switch can be set on the vehicle's central control screen to trigger the trunk carpet 1 to switch between a first position and a second position.

[0055] In some embodiments, the trunk also includes a connecting bracket, through which the slide rail 31 is connected to the lower body sheet metal. Preferably, the connecting bracket corresponds one-to-one with the slide rail 31, and extends along the front-rear direction of the trunk. The connection between the slide rail 31 and the connecting bracket can be a bolt connection, and the connection between the connecting bracket and the lower body sheet metal can also be a bolt connection. The material of the connecting bracket can be the same as that of the lower body sheet metal. Since the upper surface of the lower body sheet metal may be uneven, the connecting bracket provides a flat mounting surface for the slide rail 31, ensuring that the slide rail 31 remains level after installation and preventing it from tilting.

[0056] Secondly, this utility model provides a vehicle that includes the trunk provided in the first aspect. Since the vehicle includes the aforementioned trunk, it also possesses the aforementioned beneficial effects of the trunk, which will not be elaborated further here.

[0057] The vehicle provided in this embodiment includes the various structures of the trunk in any of the above embodiments. To avoid repetition, these will not be described again here.

[0058] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
