DETAILED DESCRIPTION

[0071] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0072] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0073] The following combination Figure 1-Figure 29 A trunk power assist device 10 and a vehicle 100 having the trunk power assist device 10 according to an embodiment of the present application will be described in detail.

[0074] It is important to understand that, see Figure 1 、 Figure 2 As shown, in this application, the first direction is the x-axis direction, the second direction is the z-axis direction, and the third direction is the y-axis direction. The first direction, the second direction, and the third direction all include the positive direction and the negative direction of the axis.

[0075] See Figure 1 、 Figure 2As shown, the luggage compartment assist device 10 according to an embodiment of the present application includes a plate body 1, a sliding member 2, a first guide rail 3 and a driving device 4. The plate body 1 has a storage area 113. The plate body 1 is connected to the sliding member 2. The first guide rail 3 extends along a first direction. The sliding member 2 is movably arranged on the first guide rail 3 along the first direction. The driving device 4 is used to drive the sliding member 2 to move along the first guide rail 3. At least part of the travel of the sliding member 2 along the first direction can drive the plate body 1 to rise and fall along the second direction. The first direction is perpendicular to the second direction.

[0076] Specifically, the storage area 113 can be used to store items. The plate 1 is movably connected to the slider 2. The first guide rail 3 provides a precise direction of movement for the slider 2. The drive device 4 provides power for the movement of the slider 2. The drive device 4 drives the slider 2 in the first direction. At least a portion of the movement of the slider 2 can drive the plate 1 to rise and fall in the second direction. Using only one set of drive devices 4, the movement of the slider 2 along the first guide rail 3 and the lifting and lowering of the plate 1 in the second direction are cleverly achieved. This greatly simplifies the structure of the luggage assist device 10, reduces the number of drive devices 4, lowers production costs, and reduces the space occupied by the luggage assist device 10, providing more space for storing items. Thus, the practicality of the luggage assist device 10 is improved. Furthermore, when the drive device 4 is activated, driving the slider 2 along the first guide rail 3 and thereby causing the plate 1 to descend in the second direction, the previously limited vertical space of the storage area 113 is significantly expanded, creating ample vertical space for placing items, allowing items to be easily stored therein and significantly increasing the vertical storage capacity of the storage area 113.

[0077] In the related art, the luggage compartment power assist device includes a plate, a sliding member, a guide rail and two driving devices. Items can be placed on the plate. One driving device is used to drive the sliding member to move along the length direction of the guide rail, and the other driving device is used to drive the plate to rise and fall. However, this structure has a large number of driving devices and is too complicated.

[0078] According to the trunk power assist device 10 of the embodiment of the present application, the driving device 4 drives the sliding member 2 to move along the first direction, and at least part of the movement of the sliding member 2 can drive the plate body 1 to rise and fall along the second direction, so that only one set of driving devices 4 can simultaneously control the movement of the sliding member 2 along the first direction and the rising and falling of the plate body 1 along the second direction, thereby reducing the number of driving devices 4, greatly simplifying the structure of the trunk power assist device 10, reducing production costs, and improving the practicality of the trunk power assist device 10.

[0079] Optionally, the first guide rail 3 may be a linear guide rail, a guide rail with balls, etc.

[0080] Optionally, a guide groove extending along the first direction is provided on the first guide rail 3 , and the sliding member 2 can move along the guide groove so that the sliding member 2 moves along a straight line, thereby preventing the movement trajectory of the sliding member 2 from being deflected.

[0081] In some embodiments of the present application, see Figure 1 、 Figure 2 As shown, the plate body 1 includes a storage plate 11 and a connecting portion 12, the connecting portion 12 is movably connected to the sliding member 2, the storage plate 11 is connected to the connecting portion 12, and the storage area 113 is provided on the storage plate 11. Specifically, the storage plate 11 is fixedly connected to the connecting portion 12, and the connecting portion 12 is movably connected to the sliding member 2, so that the plate body 1 can flexibly respond to the movement of the sliding member 2. The driving device 4 drives the sliding member 2 to move along the first guide rail 3, the sliding member 2 can drive the connecting portion 12 to rise and fall in the second direction, and the connecting portion 12 can drive the storage plate 11 to rise and fall in the second direction. When items such as suitcases and boxes are bumped or vibrated during movement, the storage plate 11 can firmly rely on the connecting portion 12 to prevent the storage plate 11 from shaking, shifting or even falling, thereby providing reliable support for items placed in the storage area 113 and reducing the risk of damage to items due to structural instability.

[0082] Optionally, the storage plate 11 may be a sheet metal part, a plastic part, a rubber part, a composite material part, etc.

[0083] Optionally, the connecting portion 12 may be a sheet metal part, a plastic part, a rubber part, a composite material part, etc.

[0084] In some embodiments of the present application, see Figures 1-4 、 Figures 18-20 As shown, the slider 2 includes a lifting structure, and the connecting portion 12 includes a driven structure that cooperates with the lifting structure. The driving device 4 drives the slider 2 in at least a portion of its travel in the first direction, thereby driving the connecting portion 12 to rise and fall in the second direction. Specifically, when the driving device 4 causes the slider 2 to move in the first direction, there is a portion of the slider 2's travel where the lifting structure cooperates with the driven structure to drive the connecting portion 12 to rise and fall in the second direction, thereby raising and lowering the storage plate 11 in the second direction. The coordination between the lifting structure and the driven structure provides precise guidance for the raising and lowering of the storage plate 11.

[0085] In some embodiments of the present application, see Figures 1-4 、 Figures 18-20 As shown, the lifting structure is the first guide groove 21, and the driven structure is the first protrusion 121. The first protrusion 121 is movably arranged in the first guide groove 21. When the driving device 4 drives the sliding member 2 to move along the first direction, the first protrusion 121 can selectively move in the first guide groove 21 to drive the storage plate 11 to rise and fall along the second direction.

[0086] Specifically, the cooperation between the first guide groove 21 and the first protrusion 121 provides extremely precise guidance for the lifting and lowering of the storage tray 11. When the drive device 4 causes the slider 2 to move in the first direction, the first protrusion 121 can only move along the predetermined trajectory of the first guide groove 21, thereby driving the connection portion 12 to rise and fall in the second direction along a precise path. The lifting of the connection portion 12 in the second direction also drives the storage tray 11 in the second direction. This precise guidance mechanism allows users to easily achieve precise positioning of the storage tray 11, greatly improving the accuracy and convenience of the luggage case assist device 10.

[0087] In some embodiments, see Figure 4 As shown, the connecting portion 12 has a connecting surface 123 , and the storage plate 11 can be fixedly installed on the connecting surface 123 .

[0088] Specifically, the storage plate 11 has a connected surface that contacts the connecting surface 123 , so that the connecting portion 12 can stably support the storage plate 11 .

[0089] Optionally, the connecting surface 123 may be a plane, a curved surface, a multi-fold surface, etc.

[0090] In some embodiments of the present application, see Figures 1-4 、 Figures 18-20 As shown, the first guide groove 21 is a long strip groove, and an angle is formed between the length extension direction of the first guide groove 21 and the first direction. The angle is non-zero, that is, the first guide groove 21 is tilted relative to the first direction.

[0091] Specifically, the elongated first guide slot 21 forms an angle with the first direction, enabling the linear movement of the slider 2 in the first direction to be efficiently converted into the lifting motion of the storage tray 11 in the second direction. When the drive device 4 pushes the slider 2 in the first direction, the first protrusion 121 moves within the inclined first guide slot 21. For example, if the first direction is horizontal and the second direction is vertical, the horizontal driving force is cleverly converted into a vertical force that lifts and lowers the storage tray 11. This simple structure achieves efficient conversion between two different directions of motion, improving energy utilization efficiency during the movement of the trunk assist device 10. The simple structure also ensures the operational stability of the trunk assist device 10.

[0092] In some embodiments of the present application, the length extension direction of the first guide groove 21 and the first direction have an angle that is not a right angle.

[0093] In some embodiments not shown in the drawings of the present application, the lifting structure may also be a protruding first track, and the driven structure may be a first slider, which is movably arranged on the first track. When the driving device 4 drives the sliding member 2 to move in the first direction, the first slider may selectively move on the first track to drive the storage plate 11 to rise and fall in the second direction, and can also provide precise guidance for the lifting and lowering of the storage plate 11.

[0094] In some embodiments of this application, see Figures 1-4 、 Figures 18-20 As shown, the trunk assist device 10 is suitable for installation in a trunk, wherein one end of the trunk is a trunk opening, and the height of the end of the first guide slot 21 closer to the trunk opening is lower than the height of the end of the first guide slot 21 farther from the trunk opening. Specifically, when the driving device 4 drives the slider 2 in a first direction toward the trunk opening, the first protrusion 121 moves from the lowest point to the highest point of the first guide slot 21, causing the connecting portion 12 and the storage plate 11 to rise in a second direction. When the driving device 4 drives the slider 2 in the first direction away from the trunk opening, the first protrusion 121 moves from the highest point to the lowest point of the first guide slot 21, causing the connecting portion 12 and the storage plate 11 to descend in the second direction.

[0095] In some embodiments, see Figures 1-4 As shown, the first guide slot 21 includes a first soft stop slot 211 and a second soft stop slot 212. The first soft stop slot 211 extends along the first direction, and the second soft stop slot 212 extends along the first direction. The second soft stop slot 212 is located at the end of the first guide slot 21 closer to the box opening, while the first soft stop slot 211 is located at the end of the first guide slot 21 farther from the box opening. The first soft stop slot 211 is located diagonally above the second soft stop slot 212. When the first protrusion 121 enters the first soft stop slot 211 or the second soft stop slot 212, it prevents the storage plate 11 from rising or falling in the second direction. Specifically, when the slider 2 moves along the negative x-axis, the first protrusion 121 moves from the lowest point of the first guide slot 21 to the highest point and enters the first soft stop slot 211. The first soft stop slot 211 restricts the movement of the first protrusion 121, and the storage plate 11 no longer rises along the positive z-axis. When the sliding member 2 moves along the negative direction of the x-axis, the first protrusion 121 moves from the highest point of the first guide groove 21 to the lowest point and enters the second soft stop groove 212. The second soft stop groove 212 limits the movement of the first protrusion 121, and the storage plate 11 no longer descends along the negative direction of the z-axis.

[0096] In the prior art, the storage plate and the connecting portion are not limited in the second direction, which can easily cause the connecting portion and the storage plate to fall off the slider or produce unusual noises during vehicle movement. In the present application, however, by providing first and second soft-stop grooves 211 and 212, the first protrusion 121 on the connecting portion 12 is limited to its extreme position during movement, preventing the connecting portion 12 and the storage plate 11 from falling off the slider 2. This also prevents unusual noises caused by the connecting portion 12 and the storage plate 11 about to fall off, thereby improving the stability of the luggage compartment assist device 10.

[0097] In some embodiments of this application, see Figure 1 、 Figure 2 As shown, at least a portion of the movement of the slider 2 in the first direction can drive the plate 1 to move in the same direction as the first direction. Specifically, a portion of the movement of the slider 2 in the first direction can cause the plate 1 to move in the same direction as the slider 2, while the remaining portion of the movement of the slider 2 in the first direction can cause the plate 1 to rise and fall in the second direction. Thus, a single set of drive devices 4 can simultaneously achieve movement of the slider 2 in the first direction, rise and fall of the plate 1 in the second direction, and movement in the first direction. This greatly simplifies the internal structure of the luggage compartment assist device 10, achieves functional integration, eliminates a set of drive devices, and therefore reduces the number of parts, thereby lowering production costs and improving product competitiveness.

[0098] In some embodiments of this application, see Figure 1-Figure 3 、 Figures 6-10 、 Figure 18 As shown, the slider 2 has a first guide structure, and the first guide rail 3 has a second guide structure that cooperates with the first guide structure. When the driving device 4 drives the slider 2 to slide in the first direction, the second guide structure slides relative to the first guide structure in the first direction. Specifically, the first and second guide structures cooperate to ensure that the slider 2 slides accurately in the first direction, restricting movement of the slider 2 in other directions. This improves motion accuracy and makes the operation of the luggage compartment assist system 10 more stable and reliable.

[0099] In some embodiments of this application, see Figure 1-Figure 3 、 Figures 6-10 、 Figure 18 As shown, the first guide structure is at least one second protrusion 22, the second guide structure is at least one second limiting groove 31, the second protrusion 22 is slidably installed in the second limiting groove 31, and when the driving device 4 drives the sliding member 2 to slide along the first direction, the second protrusion 22 slides in the second limiting groove 31.

[0100] Specifically, when the driving device 4 drives the sliding member 2 to slide along the first direction, the second protrusion 22 slides in the second limiting groove 31, which can effectively limit the movement trajectory of the sliding member 2, so that the sliding member 2 can only move smoothly along the predetermined extension direction of the second limiting groove 31, avoiding unstable phenomena such as shaking, offset or jamming of the sliding member 2 during movement.

[0101] Optionally, the number of the second protrusions 22 may be one, two, three, four or more, and the number of the second limiting grooves 31 may be consistent with the number of the second protrusions 22. Figure 3 、 Figure 7 As shown, there are three second protrusions 22 and three second limiting grooves 31, and each second protrusion 22 is slidably mounted in a corresponding second limiting groove 31. In other embodiments, the number of second limiting grooves 31 may be less than the number of second protrusions 22, and each second limiting groove 31 may be provided with a plurality of second protrusions 22.

[0102] In some embodiments not shown in the figures of this application, the first guide structure may be a second slider, the second guide structure may be a protruding second track, the second slider is installed on the second track, and when the driving device 4 drives the sliding member 2 to slide along the first direction, the second slider slides on the second track, which can also ensure that the sliding member 2 slides accurately along the first direction and limit the movement of the sliding member 2 in other directions.

[0103] In some embodiments of this application, see Figure 1 、 Figure 2 、 Figure 4 、 Figure 7-10 、 Figure 17 、 Figure 18 As shown, the first guide rail 3 has a first limiting structure, and the connecting portion 12 has a second limiting structure. When the driving device 4 drives the sliding member 2 to slide in the first direction, the first limiting structure limits the motion trajectory of the second limiting structure. Specifically, the first limiting structure and the second limiting structure cooperate to accurately limit the motion trajectory of the connecting portion 12, ensuring that the connecting portion 12 moves within a specific area, and can achieve two processes of moving the connecting portion 12 in the first direction and lifting and lowering in the second direction. This prevents the connecting portion 12 from excessively moving beyond the designed range, avoiding collisions with other components or damage to the equipment.

[0104] In some embodiments of this application, see Figure 1 、 Figure 2 、 Figure 4 、 Figure 7-10 、 Figure 17 、 Figure 18As shown, the first limiting structure is the third limiting groove 32, the second limiting structure is the third protrusion 122, the third protrusion 122 is slidably installed in the third limiting groove 32, and when the driving device 4 drives the sliding member 2 to slide along the first direction, the third protrusion 122 slides in the third limiting groove 32.

[0105] Specifically, when the driving device 4 drives the slider 2 to slide in the first direction, the third protrusion 122 slides within the third limiting groove 32, effectively restricting the movement trajectory of the connecting portion 12, forcing the connecting portion 12 to move smoothly only along the predetermined extension direction of the third limiting groove 32. This prevents the connecting portion 12 from experiencing unstable phenomena such as shaking, offsetting, or jamming during movement. Furthermore, the third limiting groove 32 provides a clear path for the movement direction of the connecting portion 12. By extending the third limiting groove 32 in different directions in different sections, the connecting portion 12 can move in different directions in different sections.

[0106] In some embodiments of this application, see Figure 17 、 Figure 18 As shown, the third limiting groove 32 includes a first section 321 and a second section 322. The second section 322 extends in the first direction, and the extension direction of the first section 321 is at an angle to the extension direction of the second section 322. The first section 321 is located on the side of the second section 322 away from the storage plate 11, and the first section 321 and the second section 322 are connected. Specifically, when the third protrusion 122 slides within the second section 322, the second section 322 extends in the first direction, so the connecting portion 12 moves in the first direction, and the storage plate 11 can move in the first direction. When the third protrusion 122 slides within the first section 321, the extension direction of the first section 321 is at an angle to the extension direction of the second section 322, so the connecting portion 12 moves in the extension direction of the first section 321, and the storage plate 11 moves with the connecting portion 12. The angle between the extension direction of the first section 321 of the third slot and the extension direction of the second section 322 of the third slot can be determined according to actual use requirements, thereby achieving various movement effects of the storage plate 11 and meeting more use requirements. For example, the angle is not zero.

[0107] In some embodiments of the present application, see Figure 17 、 Figure 18As shown, the first section 321 of the third slot extends in the second direction. Specifically, when the third protrusion 122 slides within the first section 321 of the third slot, since the first section 321 of the third slot extends in the second direction, the connecting portion 12 moves in the second direction, and the storage plate 11 can be raised or lowered in the second direction. When the third protrusion 122 slides within the second section 322 of the third slot, since the second section 322 of the third slot extends in the first direction, the connecting portion 12 moves in the first direction, and the storage plate 11 can be moved in the first direction.

[0108] In some embodiments not shown in the drawings of the present application, the first limiting structure may be a protruding third track, and the second limiting structure may be a third slider. The third slider is installed on the third track. When the driving device 4 drives the sliding member 2 to slide along the first direction, the third slider slides on the third track, which can also effectively limit the movement trajectory of the connecting part 12.

[0109] In some embodiments of this application, see Figure 15 As shown, the drive device 4 includes a driving member 41 and a transmission member 42. The transmission member 42 is connected to the sliding member 2, and the driving member 41 is connected to the transmission member 42. When the driving member 41 drives the transmission member 42 to move, the sliding member 2 moves in the first direction. Specifically, the driving member 41, as the power source of the luggage compartment assist device 10, can provide a continuous and stable driving force. The driving member 41 efficiently transmits the power to the sliding member 2 via the transmission member 42, ensuring smooth power transmission. This makes the movement of the sliding member 2 in the first direction, the lifting and lowering of the storage plate 11 in the second direction, and the movement in the first direction smoother, providing a reliable guarantee for users to place and retrieve items.

[0110] In some embodiments of this application, see Figure 1 、 Figure 2 、 Figure 15 As shown, there are at least two sliding members 2, and the at least two sliding members 2 are spaced apart along the third direction. The first direction is perpendicular to the third direction. When the driving member 41 drives the transmission member 42 to move, the sliding member 2 is driven to move along the first direction.

[0111] Specifically, each slider 2 is connected to a connecting portion 12, and at least two connecting portions 12 are connected to the same storage plate 11, providing more stable support for the storage plate 11. Simultaneously, a single driving member 41 drives at least two sliders 2 to move synchronously in the same direction, maintaining the consistency of the sliders' 2 movement pace, improving the stability of the storage plate 11 during movement, and preventing distortion or deformation of the storage plate 11 caused by inconsistent movement of the connecting portions 12.

[0112] Optionally, the number of the sliding members 2 may be two, three, four or more. For example, the number of the sliding members 2 is two.

[0113] In some embodiments of this application, see Figure 1 、 Figure 2 、 Figure 15 As shown, there are at least two transmission members 42 , the at least two transmission members 42 are connected to the at least two sliding members 2 , and the driving member 41 drives the at least two sliding members 2 to move synchronously along the first direction through the at least two transmission members 42 .

[0114] Specifically, for example, the number of driving members 41 is one, and one driving member 41 drives two sliding members 2 to move at the same time, thereby effectively reducing the number of driving members 41, simplifying the system structure of the driving device 4, saving the space occupied by the driving device 4 and reducing the weight of the trunk power assist device 10, and also helping to improve the assembly efficiency of the trunk power assist device 10 and reduce costs.

[0115] Optionally, the number of the transmission members 42 may be two, three, four or more. Figure 2 As shown, there are two transmission members 42 .

[0116] In the related art, a driver is arranged on each of the two first guide rails to independently drive the movement of the corresponding slider. The two sliders are synchronized by controlling the rotational speed of the driver, which not only increases the cost of the driver but also reduces the accuracy of the synchronized movement of the two sliders. However, the driver 4 of the present application uses a single driver 41 to drive the movement of the two sliders 2, which not only reduces production costs but also facilitates the control of the displacement accuracy of the sliders 2, ensuring the synchronized movement of the two sliders 2.

[0117] In some embodiments of this application, see Figure 15 As shown, the transmission member 42 includes a transmission body 421 and a transmission slider 422. The transmission slider 422 is connected to the sliding member 2. The transmission slider 422 is connected to the driving member 41 via the transmission body 421. The driving member 41 drives the transmission slider 422 via the transmission body 421, thereby driving the sliding member 2 to move in the first direction. Specifically, the transmission slider 422 is fixedly connected to the sliding member 2. The transmission body 421 serves as a connecting bridge between the driving member 41 and the transmission slider 422. It can accurately transmit the power of the driving member 41 to the transmission slider 422, thereby driving the sliding member 2 to move in the first direction, achieving precise and efficient power transmission and ensuring smooth movement of the storage plate 11.

[0118] Optionally, the transmission slider 422 and the sliding member 2 can be connected by welding, bolt connection, adhesive connection, rivet connection, etc. Similarly, the transmission slider 422 and the sliding member 2 can also be an integral part.

[0119] Optionally, the transmission slider 422 and the transmission body 421 may be connected by welding, bolt connection, adhesive connection, rivet connection, etc. Similarly, the transmission slider 422 and the transmission body 421 may also be an integral part.

[0120] Optionally, the transmission body 421 can be designed according to actual needs, such as using flexible shaft transmission, wire transmission, gear transmission, chain transmission, belt transmission, etc. This application takes flexible shaft transmission as an example for description, and other methods will not be described in detail.

[0121] In the prior art, the drive mechanism uses an output shaft that cooperates with two slide rails to drive the sliding elements on either side of the storage plate along the rails. However, this solution places excessively high demands on the precision of the fit (primarily parallelism) between the output shaft and the rails, making fabrication and assembly difficult. For example, if the transmission body 421 is a flexible shaft, the fit precision between the first guide rail 3 and the flexible shaft is slightly lower, allowing for an angle of 1° to 2° between the first guide rail 3 and the first direction. This approach presents a relatively low level of fabrication difficulty and simplified assembly.

[0122] In some embodiments, the transmission body 421 has a locked state. When the driver 41 stops driving the transmission body 421, the transmission body 421 enters the locked state. For example, if the transmission body 421 is a flexible shaft, when the driver 41 stops driving the flexible shaft, the gear in the driver 41 locks (or the worm gear locks), causing the flexible shaft to enter the locked state and prevent movement.

[0123] In the related art, the transmission body adopts a door zipper structure (the door zipper structure is located in the handle assembly) to drive the positioning buckle to engage with the guide rail to limit the opening and closing. When the transmission body needs to move, the door zipper structure is first pulled to open the limit of the positioning buckle and the guide rail. After the movement of the transmission body is completed, the door zipper structure is released and the limit of the positioning buckle and the guide rail is closed to achieve the locking and movement of the transmission body. However, there is a matching tolerance in the engagement of the positioning buckle and the guide rail, which causes the trunk power assist device to have problems such as mismatch and abnormal noise. In the present application, the transmission body 421 actively enters the locked state after the movement is completed, and the coordination of the positioning buckle and the guide rail is cancelled, thereby preventing the trunk power assist device 10 from having problems such as mismatch and abnormal noise. The door zipper structure is also cancelled, the structure of the trunk power assist device 10 is simplified, the difficulty of operation is reduced, and the trunk power assist device 10 is made more convenient.

[0124] In some embodiments of this application, see Figure 1 、 Figure 2 、 Figures 6-10As shown, there are two first guide rails 3, and the two first guide rails 3 are spaced apart along the third direction. The first guide rail 3 includes a guide rail body 33, a first channel 34 and a second channel 35. The guide rail body 33 extends along the first direction. The second channel 35 is provided in the guide rail body 33 and extends along the first direction. The first channel 34 is provided in the guide rail body 33 and extends along the first direction. A notch is provided at one end of the first channel 34 close to the sliding member 2, and the notch extends along the first direction. The first channel 34 and the second channel 35 are used for the transmission member 42 to pass through.

[0125] Specifically, the first channel 34 and the second channel 35 hide the transmission parts 42 (such as screw rods, belts, racks, etc.) inside the guide rail body 33, which can prevent impurities (such as dust, oil, etc.) from invading the transmission parts 42, thereby extending the service life of the transmission parts 42 and improving transmission efficiency.

[0126] In some embodiments of this application, see Figure 1 、 Figure 2 、 Figures 6-10 As shown, one end of the transmission member 42 is located in the second channel 35 of one of the two first guide rails 3, and the other end of the transmission member 42 is located in the first channel 34 of the other of the two first guide rails 3 and connected to the corresponding sliding member 2. For example, one end of the first transmission member 42 is located in the second channel 35 of the left first guide rail 3, and the other end is located in the first channel 34 of the right first guide rail 3 and connected to the right sliding member 2. One end of the second transmission member 42 is located in the second channel 35 of the right first guide rail 3, and the other end is located in the first channel 34 of the left first guide rail 3 and connected to the left sliding member 2.

[0127] Specifically, the transmission body 421 can be a flexible shaft, and the two transmission members 42 can form their own motion circuits without interfering with each other. In addition, a notch is provided on the side of the first channel 34 close to the sliding member 2 on the same side, which facilitates the connection between the transmission slider 422 passed through the first channel 34 and the sliding member 2. When the driving member 41 drives the transmission body 421 to move, the transmission body 421 drives the transmission slider 422 to move in the first channel 34, and the transmission slider 422 can drive the sliding member 2 to move, so that the driving member 41 drives the two sliding members 2 to move in the same direction, thereby realizing the movement of the storage plate 11.

[0128] In some embodiments of this application, see Figure 16 As shown, the driving member 41 includes a driving frame 411, a rotating member 412 and a driving motor 413. The two transmission members 42 are movably provided on the driving frame 411, and the rotating member 412 is rotatably provided on the driving frame 411. The two transmission members 42 are respectively provided on both sides of the radial direction of the rotating member 412. The two transmission members 42 are respectively engaged with the rotating member 412. The driving motor 413 is connected to the driving frame 411 for driving the rotating member 412 to rotate.

[0129] Specifically, the driving motor 413 drives the rotating member 412 to rotate. Since the two transmission members 42 are respectively arranged on both sides of the radial direction of the rotating member 412, when the rotating member 412 rotates (forward or reverse), the two transmission members 42 can move simultaneously in the direction of the first channel 34 or simultaneously in the direction of the second channel 35, so that the transmission slider 422 moves in the same direction in the first channel 34 in a synchronized manner, and the two sliding members 2 move in the same direction along the extension direction of the first guide rail 3. The sliding member 2 drives the connecting part 12 to move in the same direction, thereby making the storage plate 11 move smoothly in the first direction or rise and fall in the second direction.

[0130] In some embodiments, as Figure 27-Figure 29 As shown, the driving member 41 further includes a plurality of transmission wheels 414 , which are located on at least one side of the first guide rail 3 in the length direction, and are used to limit the motion trajectory of the transmission member 42 to improve the operating stability of the transmission member 42 .

[0131] In some embodiments, as Figure 27 As shown, the transmission member 42 is disposed within the first channel 34 and the second channel 35 of the same first guide rail 3 and is formed in an annular shape. The two transmission members 42 are spaced apart along the axis of the rotating member 412 and are both engaged with the rotating member 412. Thus, the drive motor 413 can provide torque to drive the rotating member 412 to rotate. The rotating member 412 can then drive the two engaged transmission members 42 to rotate in the same direction, thereby driving the sliding members 2 on the two first guide rails 3 to move in the first direction, thereby ensuring the stability of the movement of the storage plate 11 in the first direction.

[0132] In some embodiments, as Figure 28 As shown, one transmission member 42 is disposed within the first channel 34 and the second channel 35 of the same first guide rail 3 and is formed in an annular shape. Another transmission member 42 is disposed within the second channel 35 and the first channel 34 of another first guide rail 3 and is formed in an annular shape in the opposite direction to the first transmission member 42. The driving member 41 further includes two rotating members 412, which are in driving connection with each other. One of the rotating members 412 is in driving connection with the output shaft of a driving motor 413, and the two transmission members 42 are respectively engaged with the two rotating members 412. Thus, the driving motor 413 provides torque, driving the two rotating members 412 to rotate in opposite directions, thereby causing the two transmission members 42 to rotate in opposite directions. Because the annular directions of the two transmission members 42 are opposite, the two transmission members 42 rotate in the same direction in the first direction, thereby ensuring the stability of the movement of the storage plate 11 in the first direction.

[0133] In some embodiments, as Figure 29As shown, the transmission member 42 is disposed within the first channel 34 and the second channel 35 within the same first guide rail 3 and is formed in an annular shape. The driving member 41 also includes a driving shaft 415, which is connected to the output shaft of the driving motor 413. The two transmission members 42 are spaced apart along the length of the driving shaft 415 and are both meshed with the driving shaft 415. The driving shaft 415 can be specifically a synchronous belt, thereby providing torque for the driving motor 413 to drive the driving shaft 415 to rotate. The driving shaft 415 can drive the two meshed transmission members 42 to rotate in the same direction, thereby driving the sliding members 2 on the two first guide rails 3 to move in the first direction, thereby ensuring the stability of the movement of the storage plate 11 in the first direction.

[0134] In some embodiments of this application, see Figure 1 、 Figure 2 As shown, the trunk assist device 10 also includes a blocking post 5 and a blocking member 6. The blocking post 5 is positioned above the storage panel 11 and is detachably connected to the storage panel 11. There are multiple blocking posts 5, and the blocking member 6 is connected to at least two of them. The blocking member 6 is used to restrict the movement of items on the storage panel 11. Specifically, each blocking member 6 is connected to a blocking post 5 at both ends, allowing the blocking member 6 to position and limit items such as boxes, cargo, or luggage on the storage panel 11, preventing items from sliding or tipping over when the storage panel 11 is moved or when the vehicle 100 is in motion. The blocking post 5 is detachably connected to the storage panel 11, and the blocking member 6 is detachably connected to the blocking post 5. This allows the blocking post 5 and the blocking belt to be installed on the storage panel 11 when needed and removed and stored when not needed, reducing space usage.

[0135] For example, when the user wants to place or remove items on the storage plate 11, the user first moves the storage plate 11 located inside the suitcase from the initial position (such as Figure 21 Position shown) to a fixed height (such as Figure 22 After that, move the storage plate 11 to a position close to the outside of the luggage compartment (as shown in the figure). Figure 23 Place the luggage and other items on the storage board 11 (as shown in the position). Figure 24 As shown), the blocking column 5 and the blocking member 6 are fixed according to the position and size of the object (as shown Figure 24 As shown), the storage plate 11 is moved back to the inner side of the luggage compartment (not shown), and then lowered to the initial position (as shown). Figure 25 This can effectively improve the convenience of users loading and unloading objects, and can also prevent objects from sliding or tipping over during the movement of the storage plate 11.

[0136] Optionally, the blocking member 6 can be a blocking rod, a blocking net, a blocking belt, a blocking rope, etc. The material of the blocking member 6 can be an elastic net, an isolation belt, a non-woven bag, a telescopic double rod, an elastic rope, an elastic belt, etc. The blocking member 6 can be a low-cost manual hook form.

[0137] In the prior art, the blocking element uses a net bag to block items on the storage board, which has limitations. The net bag has difficulty hooking large items, and the net bag cannot effectively block small items on the storage board. However, the present invention allows the user to freely select the blocking element 6 according to the type of item. The blocking element 6 selected according to actual usage requirements ensures both the ability to hook large items and the ability to block small items.

[0138] In some embodiments of this application, see Figure 5 As shown, the storage plate 11 is provided with second guide rails 111 at both ends along the third direction. The second guide rails 111 extend along the first direction, which is perpendicular to the third direction. The blocking column 5 is movably mounted on any of the second guide rails 111. Specifically, by moving the blocking column 5 on any of the second guide rails 111, the position and angle of the blocking member 6 can be adjusted, thereby flexibly adapting to the position and size of the items on the storage plate 11 and improving the fixing effect of the blocking member 6 on the items. For example, see Figure 5 As shown, the blocking posts 5 are movably mounted on two second guide rails 111, and the blocking member 6 connects the two blocking posts 5 along the third direction to prevent items on the storage plate 11 from moving in the first direction. For another example, two blocking posts 5 are mounted on the same second guide rail 111, and the blocking member 6 has a curved surface that wraps around items (e.g., spheres, cylinders, etc.) on the storage plate 11, preventing the items on the storage plate 11 from moving in the first or third direction.

[0139] In some embodiments of this application, see Figure 5 As shown, a locking member (not shown) is provided between the blocking post 5 and the second guide rail 111, and the locking member is used to selectively lock the blocking post 5 on the second guide rail 111. Specifically, by providing the locking member, the connection stability of the blocking post 5 and the second guide rail 111 can be ensured, and the mobility of the blocking post 5 on the second guide rail 111 can be achieved when the locking member is released.

[0140] For example, the blocking column 5 is connected to the locking piece by snapping, the lower end of the blocking column 5 is provided with a snapping structure, and the upper end of the locking piece is provided with a snapping hole that cooperates with the snapping structure. The snapping structure and the snapping hole can be snapped and fixed or separated, and the assembly is simple and quick, and it is also easy to disassemble, which can improve the user's convenience. For another example, the lower end of the blocking column 5 is provided with a tooth structure, and the upper end of the locking member also has a tooth structure. When the blocking column 5 is fixed to the second guide rail 111, the lower end of the blocking column 5 and the tooth structure of the upper end of the locking member engage with each other to ensure that the blocking column 5 is fixed on the second guide rail 111. When the blocking column 5 needs to move on the second guide rail 111, the blocking column 5 is lifted so that the lower end of the blocking column 5 is away from the tooth structure of the upper end of the locking member. After adjusting the position of the blocking column 5, the blocking column 5 is lowered, and the lower end of the blocking column 5 and the tooth structure of the upper end of the locking member are re-engaged, so that the blocking column 5 and the second guide rail 111 are fixed again.

[0141] In some embodiments of this application, see Figure 1 、 Figure 2 、 Figure 4 As shown, the storage plate 11 is detachably mounted to the connecting portion 12. Therefore, if the storage plate 11 becomes damaged, such as through wear and scratches from long-term use, or cracks from impact during transport, the detachable design allows the user or maintenance personnel to remove the storage plate 11 from the connecting portion 12 and repair or replace it with a new one. This avoids the high cost of replacing the entire plate body 1 due to damage to the storage plate 11, significantly reducing maintenance costs and time. Furthermore, the detachable storage plate 11 can be removed from the connecting portion 12 to clean dust and debris, and then reattached to the connecting portion 12, greatly improving the cleaning efficiency of the trunk assist device 10.

[0142] In some embodiments not shown in the figures, the storage plate 11 and the connecting portion 12 are integrally formed. Thus, when the suitcase is subjected to bumps, vibrations, or heavy items during movement, the integral structure can better withstand external forces, preventing loosening or misalignment between the storage plate 11 and the connecting portion 12. This ensures the stability of the storage area 113, provides reliable support for items placed thereon, and reduces the risk of items falling and being damaged due to structural instability.

[0143] Optionally, the storage plate 11 and the connection portion 12 may be connected by welding, adhesive connection, snap connection, bolt connection, etc.

[0144] In some embodiments not shown in the figures, a first limiting portion 36 is provided on the first guide rail 3 .

[0145] In some embodiments not shown in the figures, a second limiting portion 37 is provided on the first guide rail 3 .

[0146] In some embodiments of the present application, see Figures 8-10 、 Figure 13 、 Figure 14 As shown, the first guide rail 3 is provided with a first limiting portion 36 and a second limiting portion 37, wherein the first limiting portion 36 is located at one end of the first guide rail 3 in the first direction, and is used to limit the first limit position of the storage plate 11 moving along the first direction, and the second limiting portion 37 is located at the other end of the first guide rail 3 in the first direction, and is used to limit the second limit position of the storage plate 11 moving along the first direction.

[0147] Specifically, the arrangement of the first stopper 36 and the second stopper 37 acts as a safety margin for the movement of the storage plate 11 and the connecting portion 12 in the first direction. Due to the sliding engagement of the first protrusion 121 with the first guide groove 21, the first stopper 36 and the second stopper 37 also limit the movement of the slider 2 in the first direction, thereby limiting the movement of the storage plate 11 in the first direction. When the slider 2 moves along the first guide rail 3 in the first direction, the first stopper 36 prevents the storage plate 11, the connecting portion 12, and the slider 2 from further moving toward the first stopper 36 when the storage plate 11 reaches the first limit position at one end of the first guide rail 3. Similarly, the second stopper 37 performs the same function at the other end of the first guide rail 3, effectively preventing the slider 2 from disengaging from the first guide rail 3 due to excessive movement, which could damage the luggage compartment assist system 10 or even items within the luggage compartment.

[0148] Optionally, the present application is described by taking the example that the first limit portion 36 is located at the extreme position of the first guide rail 3 at one end in the negative direction of the x-axis, and the second limit portion 37 is located at the extreme position of the first guide rail 3 at one end in the positive direction of the x-axis.

[0149] In some embodiments, for example Figure 9 、 Figure 10 As shown, the first limiting portion 36 can be used to abut against the sliding member 2 to limit the sliding member 2 from moving along the negative direction of the x-axis, thereby limiting the storage plate 11 from moving along the negative direction of the x-axis.

[0150] In some embodiments not shown in the present application, the first limiting portion 36 can also be used to abut against the connecting portion 12 to limit the movement of the connecting portion 12 along the negative direction of the x-axis, thereby limiting the movement of the storage plate 11 along the negative direction of the x-axis.

[0151] In some embodiments not shown in the present application, the first limiting portion 36 may also be used to directly abut against the storage plate 11 to limit the storage plate 11 from moving along the negative direction of the x-axis.

[0152] In some embodiments, for example Figure 14As shown, the second limiting portion 37 can be used to abut against the connecting portion 12 to limit the connecting portion 12 from moving along the positive direction of the x-axis, thereby limiting the storage plate 11 from moving along the positive direction of the x-axis.

[0153] In some embodiments not shown in the present application, the second limiting portion 37 can be used to directly abut against the storage plate 11 to limit the storage plate 11 from moving along the positive direction of the x-axis.

[0154] The following description uses the example of the connection portion 12 abutting against the first limit portion 36 at the first limit position and against the second limit portion 37 at the second limit position. Other types of positions are not described in detail. When the slider 2 drives the connection portion 12 in the negative x-axis direction and reaches the first limit position, the connection portion 12 abuts against the first limit portion 36, restricting movement of the connection portion 12 in the negative x-axis direction. At this point, the first protrusion 121 is located at the highest point of the first guide groove 21 and abuts against the first guide groove 21, preventing the slider 2 from further moving in the negative x-axis direction. When the sliding member 2 drives the connecting portion 12 to move in the positive direction of the x-axis and moves to the second extreme position, the connecting portion 12 stops at the second limit portion 37, and the second limit portion 37 limits the connecting portion 12 from moving in the positive direction of the x-axis. At this time, the first protrusion 121 is located at the highest point of the first guide groove 21 and stops at each other in the first guide groove 21. The sliding member 2 can continue to move in the positive direction of the x-axis, and the first protrusion 121 moves from the highest point of the first guide groove 21 to the lowest point of the first guide groove 21. The connecting portion 12 descends along the negative direction of the z-axis, and the storage plate 11 descends accordingly.

[0155] Optionally, the first limiting portion 36 and the second limiting portion 37 may adopt a conventional design solution, for example Figure 10 Optional rivet screws as shown, Figure 9 As shown, the first guide rail 3 can be punched to make flange ribs, and then Figure 14 As shown, a stopper and the like are optionally provided on the first guide rail 3 .

[0156] In some embodiments of the present application, the trunk assist device 10 further includes at least one microswitch (not shown) and a control system (not shown). When the storage tray 11 moves to the first and / or second operating conditions, the microswitch is triggered and transmits a position signal to the control system. The control system, upon receiving the position signal of the storage tray 11, controls the start and stop of the drive member 41. Specifically, by installing the microswitch in a specific position, the control system can accurately identify the position of the storage tray 11 (e.g., the height along the second direction), thereby implementing more reliable control logic and ensuring the accurate movement path of the storage tray 11.

[0157] In some embodiments of the present application, see Figure 8 、 Figure 11 、 Figure 12As shown, a weakening structure 38 is provided on the first guide rail 3. Specifically, the weakening structure 38 serves to relieve stress concentration. For example, during operation of the trunk assist device 10, the first guide rail 3 is subject to various external forces, which may cause stress concentration in a certain area of the first guide rail 3. The weakening structure 38 provides a certain amount of deformation space in the stress concentration area, allowing the stress to be dispersed and released. The first guide rail 3 is prone to collapse and deformation at the weakening structure 38. When the vehicle 100 is hit, the first guide rail 3 is subjected to the force and folds at the weakening structure 38, preventing the first guide rail 3 from colliding directly into the passenger compartment of the vehicle 100 and causing casualties.

[0158] In some embodiments of this application, see Figure 8 、 Figure 11 、 Figure 12 As shown, multiple weakening structures 38 are spaced apart along the length of the first guide rail 3. Specifically, when the vehicle 100 is impacted, the first guide rail 3 is forced to fold at the multiple weakening structures 38, thereby causing the first guide rail 3 to collapse. This prevents the entire first guide rail 3 from striking the passenger compartment of the vehicle 100 and causing casualties. This strengthens the collision safety design of the vehicle 100, thereby reducing safety hazards and improving user safety. The number of weakening structures 38 on each first guide rail 3 can be two, three, four, five, or more, and this is not specifically limited in this application.

[0159] Reference Figure 12 , the first guide rail 3 is an undeformed structure, and the first guide rail 3 ' is a deformed structure.

[0160] In other embodiments of the present application, there is one weakening structure 38 .

[0161] Optionally, the weakening structure 38 may be a weakening groove, a thickness reduction area, or a weakening hole. Figure 11 As shown, the weakening structure 38 is a weakening groove, wherein the width d1 of the weakening groove is 1 mm to 3 mm, and the depth d2 is 0.5 mm to 2.5 mm. Optionally, the width d1 of the weakening groove can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, or other values of 1 mm to 3 mm. The depth d2 of the weakening groove can be 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, or other values of 0.5 mm to 2.5 mm.

[0162] In the prior art, when a vehicle collides, the first guide rail can intrude into the vehicle due to the impact, causing casualties. In the trunk assist device 10 of the present embodiment, multiple weakening structures 38 are spaced apart on the first guide rail 3. Force is applied to the first guide rail 3, causing it to fold at these weakening structures 38, thereby causing the first guide rail 3 to collapse. This prevents the entire first guide rail 3 from colliding directly into the passenger compartment of the vehicle 100, potentially causing casualties. This strengthens the collision safety design of the vehicle 100, thereby reducing potential safety hazards and improving user safety.

[0163] In the prior art, the storage tray has a handle assembly for controlling the lifting and movement of the storage tray. However, the handle assembly placed on the storage tray can affect the loading and unloading of items. Large items can also press against the handle assembly, affecting the control of the storage tray. However, the storage tray 11 of the present application eliminates the handle assembly and instead uses a remote intelligent control or a control device installed at the luggage compartment opening to control the lifting and movement of the storage tray 11. This does not affect the placement and loading and unloading of items, and also makes the overall structure of the suitcase more beautiful and complete.

[0164] In the prior art, the sliding member and the storage plate have the same length in the first direction. This can easily cause the sliding member to intrude into the vehicle during a full-vehicle collision, resulting in casualties. However, the sliding member 2 of the present application is designed to be shorter in the first direction than the storage plate 11, preventing the sliding member 2 from intruding into the vehicle during a full-vehicle collision, thereby reducing safety hazards and improving user safety.

[0165] See Figure 26 As shown, a vehicle 100 according to another embodiment of the present application includes a trunk and the above-mentioned trunk assist device 10 .

[0166] According to the vehicle 100 of another embodiment of the present application, its trunk power assist device 10 drives the sliding member 2 to move along the first direction through the driving device 4, and at least part of the movement of the sliding member 2 can drive the plate body 1 to rise and fall along the second direction, so that only one set of driving devices 4 can simultaneously control the movement of the sliding member 2 along the first direction and the rising and falling of the plate body 1 along the second direction, thereby reducing the number of driving devices 4, greatly simplifying the structure of the trunk power assist device 10, reducing production costs, and improving the practicality of the trunk power assist device 10.

[0167] Optionally, the vehicle 100 may be a large SUV, off-road vehicle, station wagon, bus, sedan, or other vehicle with a deep trunk.

[0168] In some embodiments of the present application, see Figure 1 、 Figure 2 、 Figure 21 、 Figure 22 、 Figure 26As shown, the plate body 1 includes a storage plate 11, which has a first working state and a second working state. The height of the storage plate 11 in the first working state is greater than the height of the storage plate 11 in the second working state. When the driving device 4 drives the sliding member 2 to slide along the first direction, the storage plate 11 can selectively switch between the first working state and the second working state. Specifically, the driving device 4 drives the sliding member 2 to slide along the first direction (specifically Figure 1 When the loading plate 11 is in the second working state, the loading plate 11 is first converted from the first working state to the second working state, that is, the loading plate 11 is lifted in the second direction (specifically, the positive direction of the z-axis). When the loading plate 11 is in the second working state, the lifting stops. At this time, the loading plate 11 slides along the first direction (specifically, the negative direction of the x-axis) with the sliding member 2. After the sliding member 2 drives the connecting portion 12 to slide to the first limit position, the connecting portion 12 stops moving after abutting against the first limit portion 36. The loading plate 11 also stops moving. At this time, the user can conveniently load and unload on the loading plate 11. After the loading and unloading of items is completed, the driving device 4 reverses and drives the sliding member 2 to move along the positive direction of the x-axis. The storage plate 11 moves along the positive direction of the x-axis with the sliding member 2. After the sliding member 2 drives the connecting portion 12 to slide to the second extreme position, the connecting portion 12 and the second limit portion 37 stop and no longer move in the positive direction of the x-axis. The sliding member 2 continues to move in the positive direction of the x-axis, and the first protrusion 121 slides with the first guide groove 21, so that the connecting portion 12 is converted from the second working state to the first working state along the negative direction of the z-axis. In this way, a loading and unloading process of the storage plate 11 is completed.

[0169] In some embodiments of the present application, see Figure 1 、 Figure 2 As shown, the luggage compartment includes a luggage compartment floor, which includes a first floor 20 and a second floor 30. The second floor 30 is lower than the first floor 20. When the storage plate 11 is in the second operating state, the storage plate 11 is located on the second floor 30. Specifically, the second floor 30 is located on the side of the first floor 20 facing the rear of the vehicle. The luggage compartment assist device 10 can move the storage plate 11 from the side farther from the luggage compartment opening to the side closer to the luggage compartment opening, greatly facilitating users loading and unloading items on the storage plate 11. This solves the problem of low space utilization on the side of the luggage compartment far from the luggage compartment opening and improves space utilization in the luggage compartment. Furthermore, when the storage plate 11 is in the second operating state and located on the second floor 30, the storage plate 11 has a greater capacity for items, thereby increasing the storage space of the luggage compartment.

[0170] In some embodiments of the present application, see Figure 1 、 Figure 21 、 Figure 25As shown, when the storage plate 11 is in the second operating state, the upper surface of the storage plate 11 is flush with the upper surface of the first bottom plate 20. Therefore, when the storage plate 11 moves from the second operating state to the first operating state, the first bottom plate 20 can also restrict the movement of the storage plate 11 along the negative x-axis direction, reducing the limiting pressure between the third protrusion 122 and the third limiting groove 32 (specifically, the first section 321 of the third groove). Furthermore, when the storage plate 11 is in the second operating state, the flushness of the upper surface of the storage plate 11 with the upper surface of the first bottom plate 20 ensures a smooth and aesthetically pleasing storage surface for the entire luggage case. Compared to a design in which the upper surface of the storage plate 11 is raised above the upper surface of the first bottom plate 20, this maximizes the space utilization of the visible area of the luggage case.

[0171] In some embodiments of this application, see Figure 22-Figure 24 As shown, the thickness of the storage plate 11 is h1. When the storage plate 11 is in the first operating state, the height difference between the upper surface of the storage plate 11 and the upper surface of the first bottom plate 20 is h1+2mm to h1+4mm. Specifically, the height difference between the upper surface of the storage plate 11 and the upper surface of the first bottom plate 20 is h1+2mm to h1+4mm. This provides sufficient space for items placed on the storage plate 11, preventing oversized items from contacting the inner shell of the luggage case. It also provides sufficient clearance between the storage plate 11 and the first bottom plate 20, preventing damage caused by direct collision between the storage plate 11 and the first bottom plate 20 during movement. This improves the luggage case's storage capacity while ensuring the stability of the luggage case structure.

[0172] Optionally, the height difference between the upper surface of the storage plate 11 and the upper surface of the first bottom plate 20 may be h1+2mm, h1+3mm, h1+4mm, or other values between h1+2mm and h1+4mm.

[0173] In some embodiments of this application, see Figure 5 As shown, the storage plate 11 further has rollers 112. When the storage plate 11 moves in the first direction, the rollers 112 roll in contact with the trunk floor. Specifically, when the storage plate 11 moves in the first direction, the rollers 112 roll in contact with the trunk floor. This reduces the vertical pressure exerted on the trunk floor by luggage or other items placed on the storage plate 11, as well as the running resistance of the storage plate 11 when moving in the first direction. This protects the structural stability of the storage plate 11 and the trunk floor, while ensuring smoother and more stable movement of the storage plate 11 in the first direction.

[0174] It should be noted that the first direction is the front and rear direction of the vehicle 100, the positive direction of the x-axis is the forward direction of the vehicle body, and the negative direction of the x-axis is the backward direction of the vehicle body. The second direction is the height direction of the vehicle 100, the positive direction of the z-axis is the upward direction of the vehicle body height, and the negative direction of the z-axis is the downward direction of the vehicle body height. The third direction is the left and right direction of the vehicle body, the positive direction of the y-axis is the left direction of the vehicle body, and the negative direction of the y-axis is the right direction of the vehicle body.
