[0033] The terms “including,” “comprising,” or any other variations thereof are intended to cover non-exclusive inclusion, which includes not only the elements listed but also other elements not expressly listed.

[0034] The terms "an embodiment," "as an example," or "in an example," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which may be included in at least one embodiment or example of this application. These illustrative expressions do not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments. Where there is no conflict, the embodiments and features described in these embodiments can be combined in a suitable manner.

[0035] See Figure 1-4 This utility model provides a car, including a trunk 4. The trunk 4 includes a trunk floor, a tailgate crossbeam 43, and a cover assembly 1. The trunk floor has a storage space for storing items such as a spare tire or vehicle tools. The cover assembly 1 selectively seals the opening of the storage space. The tailgate crossbeam 43 extends along the width direction of the car. Specifically, the cover assembly 1 includes a trunk cover 11. The trunk 4 is mounted on the tailgate crossbeam 43 via a flipping mechanism 2, which can switch between two positions around a horizontal rotation axis: a first state ( Figure 5As shown): The trunk cover 11 fits into the storage space opening; second state ( Figure 7 (As shown): The trunk 4 is rotated to a horizontal position and located behind the tailgate crossbeam 43, serving as a storage table.

[0036] Optionally, the cover assembly 1 also includes a tabletop, which is fixed to the surface of the trunk cover 11 by means of adhesive bonding, fastener connection, etc. The tabletop is preferably made of a high-strength, lightweight material, such as waterproof wood or engineered materials, to achieve the effects of being lightweight, waterproof, and durable. When the cover assembly 1 is in the first state, the tabletop is located in the storage space and is fixedly connected to the bottom of the trunk cover 11. When the cover assembly 1 is in the second state, the tabletop is located above the trunk cover 11 for placing items to meet the needs of camping and other scenarios.

[0037] Please combine Figure 5 In some embodiments, the cover assembly 1 includes a flipping mechanism 2. The trunk cover 11 is mounted on the tailgate crossbeam 43 via the flipping mechanism 2. The flipping mechanism 2 includes a support rod 21. Optionally, the radial projection of the support rod 21 is "V" shaped. Specifically, the support rod 21 has a connecting section 211 and a supporting section 212. The connecting section 211 is hinged to the tailgate crossbeam 43 via a hinge or other means. The supporting section 212 is fixedly connected to the trunk cover 11 via fasteners, welding, or other means. When the trunk cover 11 is in the first or second state, the supporting section 212 is approximately horizontal. Optionally, the included angle between the connecting section 211 and the supporting section 212 is 150° to 170°. The number of support rods 21 can be one or more. Optionally, the number of support rods 21 is two, with the two support rods 21 spaced apart on the same side of the trunk cover 11 to improve stability.

[0038] Furthermore, in camping scenarios, the trunk cover 11 can be rotated 180° relative to the vehicle body via the flipping mechanism 2. In the second state, it can be opened and located on the outside of the trunk 4, i.e., behind the tailgate crossbeam 43. When cleaning the surface of the trunk cover 11, since the trunk cover 11 is located outside the storage space, it can prevent liquids or dirt generated during the cleaning process from entering the interior of the trunk 4, which helps to keep the interior of the trunk 4 clean and dry.

[0039] In one embodiment, the flipping mechanism 2 further includes a drive motor 3. The output shaft of the drive motor 3 is fixedly connected to the connecting section 211 of the support rod 21. The drive motor 3 is a stepper motor with a self-locking function in the prior art. By adjusting its rotation angle, the position of the trunk cover 11 is controlled, so as to achieve precise adjustment and stable fixation of the opening and closing of the storage space.

[0040] like Figure 8 and Figure 9As shown, the flipping mechanism 2 also includes a mounting bracket 42. The drive motor 3 is fixed to the tailgate crossbeam 43 via the mounting bracket 42. At least one end of the support rod 21 is fixedly connected to the trunk cover 11 by means of fastener connection, welding, etc., and the other end is fixedly connected to the output shaft of the drive motor 3 by means of fastener connection, etc. It should be noted that, in order to reduce costs, the flipping mechanism 2 may also omit the drive motor 3. In this embodiment, one end of the support rod 21 is hinged to the tailgate crossbeam 43 by means of hinge connection, etc., and can rotate relative to the tailgate crossbeam 43. The other end of the support rod 21 is fixedly connected to the trunk cover 11 by means of fastener connection or welding, etc.

[0041] See Figure 5 In one embodiment, the mounting bracket 42 includes a mounting base 421 and a clamping arm 422, which together form a mounting space for accommodating the drive motor 3. Optionally, the mounting base 421 is prismatic or cylindrical, and is fixedly connected to the tailgate crossbeam 43 by welding, fastener connection, or other means. The clamping arm 422 is located on the upper surface of the mounting base 421, with one part of the mounting base 421 recessed relative to the other part to form a groove. The projection of the clamping arm 422 along the width direction of the vehicle body is approximately "Ω" shaped. Specifically, the clamping arm 422 is plate-shaped, with its opposite ends fixedly connected to the mounting base 421 by fastener connection, welding, or other means. The middle part of the clamping arm 422 protrudes upward relative to its two ends to form an arc-shaped plate segment, which corresponds to the aforementioned groove position, forming the aforementioned mounting space. There is a risk of damaging the trunk cover 11 and injuring the user's hand when the user flips the trunk cover 11 by hand. Flipping the trunk cover 11 by driving the motor 3 can improve safety and make it easier to use.

[0042] The flipping mechanism 2 also includes a linkage assembly 22, and the number of linkage assemblies 22 can be one or more, see [reference]. Figure 3 and Figure 4 Optionally, the number of linkage assemblies 22 is at least two, and at least two linkage assemblies 22 are spaced apart on the same side of the trunk cover 11 and located on the side of the two support rods 21 opposite to each other.

[0043] See Figure 2The trunk 4 also includes a trim panel 41, which is fixedly connected to the tailgate crossbeam 43. The trim panel 41 extends along the width of the vehicle. The areas of the trim panel 41 corresponding to the support rod 21 and the connecting rod assembly 22 are respectively provided with a first clearance groove 411 and a second clearance groove 412. Both the first clearance groove 411 and the second clearance groove 412 can be rectangular grooves to allow clearance between the support rod 21 and the connecting rod assembly 22. When the cover assembly 1 is adjusted from the first state to the second state, the support rod 21 and the connecting rod assembly 22 rotate relative to the tailgate crossbeam 43 along the first clearance groove 411 and the second clearance groove 412, respectively. When the cover assembly 1 is in the first state, the trunk cover 11 covers the area of ​​the trunk floor corresponding to the storage space, and the support rod 21 and the linkage assembly 22 are at least partially located in the storage space and below the trunk cover 11. When the cover assembly 1 is in the second state, the support rod 21 and the linkage assembly 22 are located outside the storage space and above the trunk cover 11.

[0044] See Figure 3 The connecting rod assembly 22 includes a first rod segment 221 and a second rod segment 222, which are connected by fasteners, welding, or integral molding. The second rod segment 222 is inclined relative to the first rod segment 221 to allow for angle adjustment. Optionally, the first rod segment 221 is fixedly connected to the second rod segment 222 by bolts for ease of manufacturing and transportation.

[0045] See Figure 5-7 In some embodiments, the second rod segment 222 is a telescopic rod. Specifically, the second rod segment 222 includes an inner sleeve 23 and an outer sleeve 24. Both the inner sleeve 23 and the outer sleeve 24 are hollow cylindrical. The diameter of the outer sleeve 24 is larger than the diameter of the inner sleeve 23. The inner sleeve 23 passes through the outer sleeve 24 and can reciprocate along the inner wall of the outer sleeve 24. One end of the inner sleeve 23 that extends relative to the outer sleeve 24 is fixedly connected to the trunk cover 11. The end of the outer sleeve 24 that is away from the trunk cover 11 is fixedly connected to the first rod segment 221 by fasteners, welding, or other means, thereby saving space and avoiding occupying space in the height direction of the vehicle.

[0046] Furthermore, when the cover assembly 1 is in the second state, a telescopic rod is selected via the second rod segment 222. When the inner sleeve 23 extends relative to the outer sleeve 24, according to the torque balance principle, the torques generated by the various forces acting on the trunk cover 11 satisfy the torque balance condition. The torque is equal to the product of the force applied to the corresponding point of action and the vertical distance (i.e., the lever arm) between that point of action and the center of rotation. Figure 10As shown, with the length of the first segment 221 remaining constant, by increasing the height of the upper end of the first segment 221, the upper end of the first segment 221 is brought closer to the center of rotation along the length of the vehicle, thereby shortening the lever arm length of the force acting on the upper end of the first segment 221. Therefore, under the premise that the magnitude of the force acting on the upper end of the first segment 221 remains constant, the torque it bears decreases accordingly, thereby reducing the torque transmitted from the trunk lid 11 to the support rod 21, and further reducing the load torque that the drive motor 3 needs to overcome to achieve the opening and closing action of the trunk lid 11, thus improving the working stability of the drive motor 3.

[0047] See Figure 11 and Figure 12 In one embodiment, the second rod segment 222 further includes a fixing cap 25 and a limiting ring 26. The fixing cap 25 is fixedly connected to the outer sleeve 24 by welding, threaded connection, or other means. The limiting ring 26 is fixedly connected to the end of the inner sleeve 23 by welding, snap-fit, or other means. Furthermore, the limiting ring 26 is slidably embedded in the outer sleeve 24. The fixing cap 25 includes a fixing plate 251 and a connecting sleeve 252. Optionally, the fixing plate 251 is bent and extended from its edge to form the connecting sleeve 252. Further, the fixing plate 251 has an installation hole for the inner sleeve 23 to pass through. The diameter of the installation hole is larger than the diameter of the inner sleeve 23 and smaller than the outer diameter of the limiting ring 26. This allows the inner sleeve 23 to extend out of the outer sleeve 24 and slide relative to the outer sleeve 24 without affecting its movement. At the same time, it can cooperate with the limiting ring 26 to limit the maximum length of the portion of the inner sleeve 23 extending relative to the outer sleeve 24, preventing the inner sleeve 23 from coming out.

[0048] Optionally, the outer sleeve 24 has an arc-shaped radial projection, and the inner sleeve 23 is adapted to the shape of the outer sleeve 24. The arc-shaped outer sleeve 24 and inner sleeve 23 ensure smoother sliding of the inner sleeve 23 along the inner surface of the outer sleeve 24. The axial length of the limiting ring 26 is 5~15mm, for example, 10mm. The outer diameter of the limiting ring 26 is slightly smaller than the inner diameter of the outer sleeve 24. During installation, the limiting ring 26 is fixedly connected to the end of the inner sleeve 23 away from the trunk lid 11, and the fixing cap 25 is fitted onto the inner sleeve 23. Then, the limiting ring 26 is inserted into the inner sleeve 23, and the fixing cap 25 is fixedly connected to the outer sleeve 24.

[0049] See Figure 10 Optionally, the cover assembly 1 also includes a mounting plate 27. Specifically, the mounting plate 27 is fixedly connected to one end of the inner sleeve 23 near the trunk cover 11 by welding or other means, and is fixedly connected to the trunk cover 11 by fastener connection or welding or other means.

[0050] The working principle of the cover plate assembly 1 in this utility model is as follows: After the drive motor 3 is powered on, the output shaft of the drive motor 3 begins to rotate, driving the support rod 21 to rotate relative to the vehicle body around the horizontal rotation axis, thereby causing the trunk cover 11 to flip; when the trunk cover 11 flips, for example, during the process of the cover assembly 1 adjusting from the first state to the second state, the trunk cover 11 is first located at a preset first angle (e.g. Figure 5 As shown), the drive motor 3 drives the support rod 21 to rotate, causing the trunk cover 11 to flip, thereby causing the inner sleeve 23 to extend relative to the outer sleeve 24. The stroke of the inner sleeve 23 reaches its maximum, that is, the length of the part of the inner sleeve 23 extending out of the outer sleeve 24 reaches its maximum length (as shown). Figure 6 As shown), the drive motor 3 continues to drive the trunk cover 11 to flip, and drives the outer sleeve 24 and the first rod segment 221 fixedly connected to the outer sleeve 24 to rotate through the inner sleeve 23. At this time, the entire linkage assembly 22 rotates around the horizontal rotation axis until the trunk cover 11 flips to the preset second angle (as shown). Figure 7 As shown), the trunk cover 11 is positioned horizontally. It is understandable that retracting the trunk cover 11, i.e., adjusting the trunk cover 11 from the second state to the first state, is the same process as opening it, and will not be described further here.

[0051] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
