[0037] The vehicle 200 according to the first embodiment of the present application will be described below with reference to Figures 1-5 , which is a guardrail lifting device 100.

[0038] As shown in Figures 1-4 , the guardrail lifting device 100 of the vehicle 200 according to the embodiment of the present application is used to be mounted on the vehicle body 60 having a loading space 62.

[0039] Here, the guardrail lifting device 100 is suitable for various types of vehicles 200, including but not limited to pickup trucks, ordinary van and SUV, etc. with top loading capacity.

[0040] For example, when the vehicle 200 is a pickup truck, the guard lifting device 100 can be arranged on the pickup truck's cargo bed to realize the lifting and lowering of goods, thereby enhancing the loading and unloading capacity of the pickup truck. For another example, when the vehicle 200 is a common van, the guard lifting device 100 can be arranged on the side or rear of the cargo compartment to facilitate the loading and unloading of goods. In addition, the guard lifting device 100 of the present application can also be applied to vehicles 200 with loading capacity on the top, such as arranging the guard lifting device 100 on the top of an SUV, through the loading space 62 arranged on the roof, to help users more conveniently carry goods up and down, thereby improving the functionality and practicality of these vehicles 200.

[0041] The guard lifting device 100 comprises a mounting seat 10, a guard assembly 20, a rotating driving assembly 30 and a lifting assembly 40, the mounting seat 10 is arranged on the vehicle body 60, at least part of the guard assembly 20 is adapted to surround the periphery of the loading space 62, one end of the guard assembly 20 is provided with a rotating shaft 21, the rotating shaft 21 is rotatably connected to the mounting seat 10, the rotating driving assembly 30 comprises a push rod 31, a moving piece 34 and a moving driving piece 35, both ends of the push rod 31 are respectively provided with a first hinged part 32 and a second hinged part 33, the first hinged part 32 is rotatably connected to the guard assembly 20, and the first hinged part 32 is arranged in a spaced manner with the rotating shaft 21, the moving piece 34 is movably arranged on the mounting seat 10 along a first direction, the second hinged part 33 is rotatably connected to the moving piece 34, and the moving driving piece 35 is connected to the moving piece 34 to drive the moving piece 34 to move, the lifting assembly 40 is arranged on the guard assembly 20, and the lifting assembly 40 is arranged in a spaced manner with the rotating shaft 21.

[0042] It can be seen that the mounting seat 10 is mounted on the vehicle body 60, the hoisting assembly 40 is arranged on the guardrail assembly 20, the guardrail assembly 20 is mounted on the mounting seat 10 through the rotating shaft 21, and the rotating driving assembly 30 is mounted on the mounting seat 10 through the moving piece 34. Therefore, the mounting seat 10 can be used to support the guardrail assembly 20, the hoisting assembly 40 and the rotating driving assembly 30, so that the hoisting assembly 40 is more stable when hoisting the goods. The two ends of the push rod 31 are respectively provided with the first hinge part 32 and the second hinge part 33. The first hinge part 32 is rotationally connected to the guardrail assembly 20, so that the push rod 31 and the guardrail assembly 20 can rotate relative to each other. The second hinge part 33 is rotationally connected to the moving piece 34, so that the push rod 31 and the moving piece 34 can rotate relative to each other. The moving driving piece 35 can drive the moving piece 34 to move in the first direction. By changing the arrangement position of the moving piece 34, the relative position of the push rod 31 and the guardrail assembly 20 can be indirectly changed. That is, the guardrail assembly 20 can be driven to rotate around the rotating shaft 21 through the rotating driving assembly 30, so as to drive the hoisting assembly 40 to rotate, so as to change the relative position of the guardrail assembly 20 and the hoisting assembly 40 and the vehicle body 60. This facilitates the subsequent loading and unloading of the hoisting assembly 40, so that the vehicle 200 is more convenient for loading and unloading goods, and can meet different application environments of the vehicle 200.

[0043] Exemplarily, the relative position of the guardrail assembly 20 and the hoisting assembly 40 and the vehicle body 60 can be changed through the rotating driving assembly 30, so that the guardrail assembly 20 and the hoisting assembly 40 have a switchable first turning angle position a, a second turning angle position b and a third turning angle position c. Therefore, the guardrail assembly 20 and the hoisting assembly 40 can be adjusted to three different turning angle positions according to needs to perform different functions (for example, protecting goods or loading and unloading goods).

[0044] In combination Figure 2 When the guardrail assembly 20 is located at the first turning angle position a, part of the guardrail assembly 20 surrounds the periphery of the loading space 62, and the horizontal projection of the hoisting assembly 40 is located above the vehicle 200. Here, “above the vehicle 200” includes but is not limited to the loading space 62. For example, when the vehicle 200 is a pickup truck or a truck, the loading space 62 is the pickup truck's car body and the truck's carriage. At this time, when the guardrail assembly 20 is at the first turning angle position a, the horizontal projection of the hoisting assembly 40 can be in the pickup truck's car body or the truck's carriage area.

[0045] Of course, the present application is not limited thereto, and “above the vehicle 200” also includes above the cab. In this way, when the guardrail assembly 20 is located at the first turning angle position a, the horizontal projection of the hoisting assembly 40 is moved to above the cab. This arrangement allows the hoisting assembly 40 to be stored above the cab when not in use, thereby avoiding the hoisting assembly 40 from occupying the limited loading space 62. In this way, the convenience of loading and unloading goods is ensured, and the space resources of the vehicle 200 are maximized.

[0046] In combination Figure 3 When the guardrail assembly 20 is located at the second turning position b, the hoisting assembly 40 is adapted to move to a position above the horizontal projection of the vehicle body 60. The horizontal projection of the hoisting assembly 40 can be beyond the horizontal projection of the vehicle body 60, which facilitates the hoisting operation from the rear or side of the vehicle 200. When hoisting the goods, the hoisting assembly 40 can be directly operated above the outside of the vehicle 200, avoiding the interference between the goods and the structure of the vehicle 200 during loading and unloading.

[0047] In combination Figure 4 When the guardrail assembly 20 is located at the third turning position c, the hoisting assembly 40 is adapted to move to a position above the loading space 62 to lower the hoisted goods into the loading space 62. By moving the hoisting assembly 40, the movement of the hoisted goods can be facilitated. Specifically, when loading the goods, the guardrail assembly 20 is located at the second turning position b, and the hoisting assembly 40 hoists the goods. Subsequently, the guardrail assembly 20 is turned to the third turning position c, and the hoisting assembly 40 is moved to a position above the loading space 62 and lowers the goods into the loading space 62, completing the loading. Conversely, when unloading the goods, the guardrail assembly 20 enters the third turning position c, and the hoisting assembly 40 hoists the goods in the loading space 62. Then, the guardrail assembly 20 is turned to the second turning position b, so that the hoisting assembly 40 is located above the space outside the vehicle 200, and then the goods are safely lowered to the ground or other designated positions. Through this operation mode, whether it is loading or unloading, efficient and safe handling of goods can be achieved, reducing the need for manual handling and related risks, and greatly improving the overall efficiency and safety of loading and unloading goods.

[0048] In this embodiment, at least part of the guardrail assembly 20 is adapted to surround the periphery of the loading space 62. The guardrail assembly 20 can play a role in safety protection, preventing the goods from sliding or moving during transportation.

[0049] It should be noted that the "surrounding the periphery of the loading space 62" described herein means that the guardrail assembly 20 adjusts the position according to actual needs to form protection or limitation for the loading space 62, ensuring the safety and stability of the goods during transportation. The "surrounding" is understood in a broad sense, i.e., not limited to complete closed surrounding, for example, it can also be semi-surrounding, partial blocking, or other forms of partial surrounding, etc. In this way, the structure and position of the guardrail assembly 20 can be flexibly adjusted according to different types of vehicles 200 and loading requirements, which can provide necessary safety protection without occupying too much loading space 62.

[0050] In addition, the hoisting assembly 40 is used for hoisting the goods, so that the additional hoisting equipment such as a forklift is not needed, and the hoisting operation can be directly performed by the hoisting assembly 40 in the guardrail hoisting device 100, the difficulty of outdoor carrying is reduced, the risk of manual carrying is reduced, and the work efficiency is improved; the hoisting assembly 40 is arranged at intervals from the rotating shaft 21, so that a certain distance is formed between the hoisting assembly 40 and the rotating shaft 21, and the hoisting assembly 40 and the rotating shaft 21 do not interfere with each other.

[0051] Optionally, the hoisting assembly 40 includes, but is not limited to, an electric hoist, a manual winch, or a hydraulic crane.

[0052] In some embodiments, the hoisting assembly 40 and the rotating shaft 21 are respectively located at two ends of the guardrail assembly 20 along the length direction. Alternatively, the hoisting assembly 40 is located at a middle position of the guardrail assembly 20, so that the lifting and lowering operations of the goods can still be effectively performed while the structure is kept compact.

[0053] As shown in Figures 1-5 In some embodiments, the rotating driving assembly 30 further includes a lead screw 36 and a nut 37, the lead screw 36 is arranged on the mounting base 10 along the first direction, the moving driving part 35 is connected with the lead screw 36 to drive the lead screw 36 to rotate, and the nut 37 is matched with the lead screw 36, and the moving part 34 is connected with the nut 37.

[0054] It can be seen that through the transmission mode of the lead screw 36 and the nut 37, when the moving part 34 drives the lead screw 36 to rotate, the nut 37 can move along the lead screw 36 in the first direction, thereby indirectly driving the movement of the moving part 34, and the relative positions of the guardrail assembly 20 and the hoisting assembly 40 and the vehicle body 60 are adjusted.

[0055] In addition, the design of the lead screw 36 and the nut 37 makes the rotating driving assembly 30 more compact, is easy to integrate into various devices, helps to save the space occupied by the rotating driving assembly 30, facilitates to reduce the overall size and weight of the rotating driving assembly 30, is conducive to realizing the miniaturization design of the guardrail hoisting device 100, and the thread of the lead screw 36 and the nut 37 are matched tightly and firmly, so that the lead screw 36 and the nut 37 can bear larger axial force and radial force, the entire rotating driving assembly 30 has higher load capacity, and the limitation of the hoisting weight of the hoisting assembly 40 is reduced.

[0056] Optionally, in some types of lead screws 36 (such as trapezoidal lead screws), when the lead screw 36 stops rotating, the nut 37 is automatically locked on the lead screw 36, the movement of the moving part 34 due to external force is prevented, the hoisting assembly 40 is more stable when hoisting the goods, and the reliability of the work of the guardrail hoisting device 100 is improved.

[0057] As shown in Figures 1-5As shown, in some embodiments, the moving drive 35 is a motor, and the motor is coaxially disposed at one end of the lead screw 36, and the motor is mounted on the mounting base 10.

[0058] As can be seen, the motor is coaxially mounted at one end of the lead screw 36, which reduces intermediate transmission links such as gears and belts, thereby reducing energy loss and making the motor transmit power more efficiently. At the same time, the coaxial mounting makes the motor and the lead screw 36 closer in space, which helps to save installation space and makes the structure of the rotary drive assembly 30 more compact, making it easier to reduce the space occupied by the rotary drive assembly 30.

[0059] The rotary drive assembly 30 further includes at least two support seats 12 disposed on the mounting base 10. The at least two support seats 12 are spaced apart along a first direction. Each support seat 12 is provided with a bearing. The lead screw 36 is rotatably disposed on the bearings of the at least two support seats 12. Thus, the lead screw 36 can rotate relative to the support seats 12 through the bearings. The support seats 12 are less likely to affect the normal operation of the lead screw 36. Furthermore, by spaced apart along the first direction, the lead screw 36 can be supported by the at least two support seats 12, effectively reducing the possibility of the lead screw 36 shaking or wobbling during rotation, thereby making the working position of the lead screw 36 more stable and improving the stability of the entire rotary drive assembly 30.

[0060] It is understood that there can be multiple support seats, such as three, four, or six support seats 12. Multiple support seats 12 can jointly support the lead screw 36 so that the lead screw 36 can be stably supported and thus the lead screw 36 can maintain a stable working position.

[0061] like Figures 1-5 As shown, in some embodiments, the rotation drive assembly 30 further includes a guide rail 38 and a slider 39. The guide rail 38 is disposed on the mounting base 10 along a first direction, and the slider 39 is fitted on the guide rail 38. The moving member 34 is connected to the slider 39, so the moving member 34 can move along the guide rail 38 along the first direction with the slider 39. The guide rail 38 provides a clear linear motion path for the slider 39, so that the moving member 34 can move accurately along the first direction. The motion path of the moving member 34 is clearer, and it is not easy to produce deviation or misalignment, which helps to improve the reliability of the rotation drive assembly 30.

[0062] like Figure 5 and Figure 6As shown, in some embodiments, the guide rail 38 comprises: a first rail beam 38a and a second rail beam 38b, the first rail beam 38a is arranged to extend along the first direction, the lower end of the first rail beam 38a is connected to the mounting base 10, the second rail beam 38b is arranged to extend along the first direction, the second rail beam 38b is arranged perpendicularly to the first rail beam 38a, the upper end of the first rail beam 38a is connected to the middle position of the second rail beam 38b, the sliding block 39 is provided with a sliding groove 39a, the second rail beam 38b is fitted in the sliding groove 39a, for example, the first rail beam 38a and the second rail beam 38b are configured as a T-shaped structure, the horizontal beam of the T-shaped structure is the second rail beam 38b, the vertical beam of the T-shaped structure is the first rail beam 38a, the structure of the guide rail 38 is relatively simple, and the guide rail 38 is convenient to process and manufacture.

[0063] As can be seen, the second rail beam 38b is fitted in the sliding groove 39a, so that the guide rail 38 and the sliding block 39 are more closely contacted, the guide rail 38 and the sliding block 39 are not easy to be separated, the stability of the sliding block 39 during movement is improved, and the reliability of the operation of the rotating driving assembly 30 is improved; the upper end of the first rail beam 38a is connected to the middle position of the second rail beam 38b, so that the force acting on the second rail beam 38b can be better transmitted to the first rail beam 38a, the first rail beam 38a can disperse the force to the mounting base 10, the carrying capacity of the guide rail 38 is improved, the second rail beam 38b is not easy to produce stress concentration and other problems, so that the second rail beam 38b is not easy to produce large deformation during use, and the service life of the guide rail 38 is improved.

[0064] As shown in FIG. 1, Figures 1-5 As shown, in some embodiments, the moving piece 34 is connected above the sliding block 39, the push rod 31 is located above the guide rail 38, and during the process that the guardrail assembly 20 rotates from one limit position to another limit position, for example, the guide rail 38 has a first end and a second end which are oppositely arranged along the first direction, when the sliding block 39 moves to the first end or the second end, the first hinge part 32 is located above the second hinge part 33 and the rotating shaft 21, so as to avoid that the three points are arranged in a line.

[0065] As can be seen, if the first hinge part 32, the second hinge part 33 and the rotating shaft 21 are collinear, the moving piece 34, the push rod 31 and the guardrail assembly 20 are parallel, which will make the guardrail assembly 20 move into a dead point position (the transmission angle is zero), at this time, the guardrail assembly 20 cannot continue to rotate or needs a large driving force, by limiting the first hinge part 32 to be always located above the second hinge part 33 and the rotating shaft 21, the three points can be avoided to be collinear, so that the guardrail assembly 20 has no dead point in the whole stroke, and the continuous movement of the guardrail assembly 20 is facilitated.

[0066] As shown in FIG. 1, Figures 1-5As shown, in some embodiments, the guardrail lifting device 100 further includes a detection element 50 and a controller. The detection element 50 is used to detect the position of the guardrail assembly 20, and the controller is electrically connected to the detection element 50 and the moving drive element 35.

[0067] As can be seen, the detection element 50 can be used to detect the position of the guardrail assembly 20, and the detection element 50 can feed back the detection results to the controller. At the same time, the controller can also control the moving drive element 35. Thus, the relative positions of the guardrail assembly 20 and the lifting assembly 40 with the vehicle body 60 can be adjusted through the detection element 50 and the control element, reducing the need for human intervention and facilitating automated loading and unloading of goods. At the same time, the detection element 50 and the control element can keep the guardrail assembly 20 and the lifting assembly 40 in the correct position, making it less likely to fall during loading and unloading of goods, thus improving the safety of the guardrail lifting device 100.

[0068] Optional, such as Figure 2 As shown, the detection element 50 is set on the loading space 62, located below the guardrail assembly 20, and the detection element 50 is close to one end of the lifting assembly 40, so that the position of the guardrail assembly 20 can be detected in time.

[0069] like Figures 1-5 As shown, in some embodiments, the detection element 50 is mounted on the mounting base 10, and the detection element 50 is located at the end of the mounting base 10 away from the rotation axis 21. The rotation drive assembly 30 can drive the guardrail assembly 20 to rotate around the rotation axis 21. By setting the position of the detection element 50, it is less likely to interfere with the rotation of the guardrail assembly 20. At the same time, the detection element 50 and the rotation axis 21 are spaced apart, so that the detection element 50 can make fuller use of the space on the mounting base 10, making the structure of the guardrail lifting device 100 more compact. Moreover, the detection element 50 can more easily detect the position of the guardrail assembly 20, which facilitates more precise control of the position of the guardrail assembly 20.

[0070] like Figure 1 As shown, in some embodiments, there are two mounting bases 10, and the two mounting bases 10 are installed on opposite sides of the loading space 62. The guardrail assembly 20 includes two side guardrails 22, which are arranged on opposite sides of the loading space 62. One end of each side guardrail 22 is provided with a rotating shaft 21. The rotating shafts 21 of the two side guardrails 22 are coaxially arranged and are installed on the two mounting bases 10 one by one.
