[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Embodiment 1

[0061] like Figure 1 to Figure 5 As shown, the telescopic lifting structure 1 for use in a vehicle cargo compartment provided by an embodiment of the present invention includes two first slide rails 11 , a lifting adjustment portion and an electric hoist 14 .

[0062] When in use, the two first slide rails 11 are arranged in parallel and spaced apart on the top of the cargo compartment of the vehicle (see Figure 11 to Figure 14 ), the first slide rail 11 includes a first track 111 and a first slider 112, the first track 111 is fixedly mounted on the warehouse body 2, and the first slider 112 can slide along the first track 111.

[0063] See also Figure 1 , Figure 2 and Figure 8 As shown, the hoisting adjustment part includes two second slide rails 12, and the two second slide rails 12 are arranged in the same direction as the two first slide rails 11. The second slide rail 12 includes a second track 121 and a second slider 122, and the second tracks 121 of the two second slide rails 12 are respectively installed on the inner sides of the two first sliders 112, so that the two second tracks 121 are arranged relatively spaced apart and can slide along the first track 111 with the first slider 112.

[0064] The electric hoist 14 is disposed between the two second slide rails 12 , connected to the two second sliders 122 , and can slide along the second rails 121 along with the second sliders 122 .

[0065] When in use, the first slider 112 slides relative to the first rail 111, driving the electric hoist 14 to reach the lifting position, and then moves in the opposite direction after the goods are lifted to lift the goods into the warehouse. The use of two parallel and spaced first rails 11 can achieve stable lifting, and the electric hoist 14 occupies a small space. In addition, the electric hoist 14 is connected to the first rail 11 through a lifting adjustment part, so that the electric hoist 14 can move with the first slider 112, and under the action of the lifting adjustment part, when the first rail 11 does not slide, the electric hoist can slide independently with the second rail 12. On the one hand, when necessary, the travel of the electric hoist 14 can be increased to a certain extent (see Figure 4 ), when there is no need to increase the stroke, the electric hoist 14 can be kept in a more suitable lifting position (see Figure 2 and Figure 3 ), taking into account the requirements of travel and hoisting stability, on the other hand, when folding, the electric hoist 14 can be put into the warehouse for a distance (see Figure 1 ) to enable the cargo door to be closed and avoid hitting the cargo door during driving, and avoid accidentally injuring the person opening the door when opening it.

[0066] In order to further finely adjust the position of the electric hoist 14 and better meet the lifting needs, in one example, see Figure 1 , Figure 3 and Figure 7 As shown, the second rail 121 is slidably mounted on the first slider 112 through the adapter 15. The adapter 15 includes an adapter seat 151 and a third slider 152. The adapter seat 151 is fixedly mounted on the first slider 112, and the third slider 152 is fixedly mounted on the adapter seat 151. One side of the second rail 121 is slidably connected to the third slider 152, and the other side is slidably connected to the second slider 122. That is, the second rail 121 is a common rail for the second slider 122 and the third slider 152. On the one hand, the structure is simplified, and on the other hand, by setting the adapter 15, the structural requirements for the first slide rail 11 can be reduced. For example, the existing linear guide rail on the market can be directly purchased as the first slide rail, and the second slide rail 12 can be installed on the purchased linear guide rail through the adapter 15.

[0067] See also Figure 7 and Figure 8 As shown, in one example, the cross section of the second rail 121 is I-shaped, a sliding groove on one side cooperates with the second slider 122 , and a sliding groove on the other side cooperates with the third slider 152 .

[0068] See also Figure 7 , Figure 8 and Fig.10As shown, in one example, the adapter 151 includes a first mounting plate and a second mounting plate. The first mounting plate and the second mounting plate are perpendicularly connected and have an L-shaped cross-section. The first mounting plate is fitted and mounted on the surface of the first slider 112, and the second mounting plate is located inside the first slide rail 11 for mounting the third slider 152, thereby realizing the connection and installation of the second track 121.

[0069] To facilitate the disassembly and assembly of the electric hoist 14 and reduce the structural modification of the second slide rail 12, in one example, refer to Figure 1 、 Figure 2 and Fig. 9 As shown, the electric hoist 14 is fixedly connected to two second sliders 122 through the mounting seat 13, and the electric hoist 14 is detachably mounted on the mounting seat 13. Preferably, the cross-section of the mounting seat 13 is in a "ji" shape, and the electric hoist 14 is mounted inside the "ji" shape, further reducing the occupied space area. When disassembling, assembling, or replacing and repairing, the mounting seat 13 can be removed or replaced.

[0070] To minimize weight and facilitate the fixing operation of the electric hoist 14, in one example, the mounting seat 13 is provided with a hollow.

[0071] Similarly, to minimize weight and facilitate the fixing operation of the third slider 152 and the fixed connection with the first slider 112, in one example, refer to Fig.10 As shown, the adapter 151 is provided with a hollow.

[0072] In this embodiment, refer to Figure 2 and Figure 6 As shown, the first slider 112 slides relative to the first track 111 through a ball screw pair 113, and the first slide rail 11 further includes a motor 114 for providing power to the ball screw pair 113.

[0073] Preferably, in this embodiment, a limiting device is provided between the first slide rail 11, the second slide rail 12, the third slider 152, and the second track 121 to improve safety. The limiting device can be an electrical limit, a mechanical limit, or a combination of both, which is not limited herein. The specific structure can adopt the existing technology and will not be elaborated herein.

[0074] In addition, the control and braking of the slide rail can adopt the existing technology. For example, when in use, the locking state of the slide rail can be released by pulling the brake cable on the controller to realize the sliding of the electric hoist, and the slide rail is automatically locked when the brake cable is released, which will not be elaborated herein.

[0075] Embodiment 2

[0076] As Fig.11 and Fig.12As shown, the vehicle-mounted cargo warehouse provided in the second embodiment includes a warehouse body 2 and any telescopic lifting structure 1 in the first embodiment. The vehicle-mounted cargo warehouse can stably lift the cargo, and the telescopic lifting structure 1 can be completely retracted into the cargo warehouse, which is conducive to popularization and use.

[0077] The telescopic lifting structure 1 can be lifted only by fixing the first rail 111 on the top of the warehouse body 2. Preferably, a mounting groove 21 is provided on the outer side of the top of the warehouse body 2, and a sliding channel 211 is provided at the bottom of the mounting groove 21 along the sliding direction of the first slide rail 11. Two first rails 111 are installed at the bottom of the mounting groove 21 and are located on both sides of the sliding channel 211. The hook of the electric hoist 14 extends into the warehouse body 2 through the sliding channel 211, which meets the lifting and movement requirements of the electric hoist 14, and can lift the goods from the loading and unloading port 23 into the warehouse body 2.

[0078] See also Fig.13 As shown, a detachable cover plate 22 is provided at the slot opening of the installation slot 21 to cover and protect the telescopic lifting structure 1 .

[0079] See also Fig.14 As shown, a vehicle-mounted cargo warehouse with a loading and unloading port 23 located on the side is provided. Due to the telescopic lifting structure 1 of the present invention, the electric hoist can be completely retracted into the warehouse body. Therefore, the telescopic lifting structure 1 can be applicable to the situation where the loading and unloading port 23 is on any side of the warehouse body.

[0080] It should be noted that the warehouse body can be a vehicle-mounted cabin, a compartment of a van, or a container, etc.

[0081] The parts not described in detail in this embodiment are common knowledge or existing technologies in the field.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
