[0033] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0034] Embodiment 1

[0035] This embodiment relates to a trunk article loading and unloading device, and provides an auxiliary loading and unloading device for articles and cargo in a trunk; an exemplary structure thereof is as follows Figure 1 , Figure 2 , Figure 3 and Figure 4 shown.

[0036] In general, the trunk article loading and unloading device comprises a fixed frame 1 fixed in the trunk, a lifting tray 2 which is guided and movable on the fixed frame 1, and a driving unit. The lifting tray 2 has a first position which is moved to the inside of the trunk and a second position which is moved out to the rear of the trunk, and the lifting tray 2 at the second position can be lifted and moved under the driving of the driving unit.

[0037] Specifically, the fixing frame 1 of this embodiment includes a front cross beam 11, and side longitudinal beams 12 respectively connected to the left and right ends of the front cross beam 11; both side longitudinal beams 12 are arranged along the front and rear direction of the vehicle, and the lifting tray 2 is guided on the side longitudinal beams 12. The fixing frame 1 adopts a "door"-shaped frame structure, and the two side longitudinal beams 12 can provide a good guiding structure to achieve the front and rear guided movement of the lifting tray 2.

[0038] In order to realize the horizontal guided movement of the lifting tray 2 on the fixed frame 1, in this embodiment, guide grooves 120 are provided on the two side longitudinal beams 12, and guide seats 310 are slidably provided in the guide grooves 120; the lifting tray 2 is arranged on the two guide seats 310. By providing the guide grooves 120 on the side longitudinal beams 12, the lifting tray 2 is driven to move forward and backward by the guide seats 310, so that the movement of the lifting tray 2 between the first position and the second position is realized.

[0039] In addition, the lifting tray 2 and the guide seat 310 are connected via a lifting mechanism 31; driven by the driving unit, the connection height of the lifting mechanism 31 can be changed so that the lifting tray 2 can be lifted relative to the guide seat 310. The setting of the lifting mechanism 31 between the guide seat 310 and the lifting tray 2 allows the lifting tray 2 to move up and down relative to the guide seat 310, thereby realizing the lifting and moving function of the lifting tray 2 well.

[0040] Of course, the lifting mechanism 31 can be arranged in various ways. Figure 1 , Figure 4 and Figure 5 As shown, the lifting mechanism 31 adopts a connecting rod lifting mechanism. The connecting rod lifting mechanism is used to connect the guide seat 310 and the lifting tray 2, so as to realize the stable lifting function of the lifting tray 2. The lifting tray 2 can maintain a good horizontal posture during the lifting process relative to the fixed frame 1, so as to facilitate loading of mobile articles, goods, etc. The connecting rod lifting mechanism has the characteristics of simple structure, stable performance, and easy processing and construction.

[0041] Specifically, a slide groove 22 arranged along the left and right directions of the vehicle is provided on the lifting tray 2, and the link lifting mechanism includes a first link 311 and a second link 313; the top ends of the first link 311 and the second link 313 are respectively hinged on the two guide seats 310, and the bottom ends of the first link 311 and the second link 313 are both slidably arranged in the slide groove 22. The first link 311 and the second link 313 are used, and the first slider 312 and the second slider 314 are respectively arranged at their bottom ends, so that the first slider 312 and the second slider 314 slide in the slide groove 22 on the lifting tray 2, thereby realizing the lifting function of the lifting tray 2; moreover, this arrangement form uses the least number of links, which can simplify the structure of the lifting mechanism 31, thereby reducing the overall weight of the trunk article loading and unloading device.

[0042] In addition, the lifting tray 2 of this embodiment adopts a rectangular frame structure, and has a rectangular frame 20, which includes a front frame 201, a first side frame 203, a rear frame 202 and a second side frame 203 connected to each other at the end; the above-mentioned slide groove 22 can be set on the front frame 201. Among them, the two side frames 203 in the frame 20 are respectively set corresponding to the two side longitudinal beams 12; the side frames 203 are provided with a receiving groove 23 with an open opening facing downwards, and when the lifting tray 2 is located at the first position, the side longitudinal beam 12 is received in the receiving groove 23 of the side frame 203 on the same side. The above-mentioned design form has a simple and practical structure; the side frames 203 on both sides are respectively arranged corresponding to the two side longitudinal beams 12. By utilizing the accommodating grooves 23 on the side frames 203, when the lifting tray 2 is horizontally moved into the trunk, the two side longitudinal beams 12 of the fixing frame 1 will be covered, thereby keeping the bottom of the trunk tidy and preventing items and debris from falling into the guide grooves 120 on the side longitudinal beams 12, thereby ensuring the performance stability of the guide structure between the fixing frame 1 and the lifting tray 2.

[0043] In addition, multiple supporting rods 21 can be selectively provided in the frame 20; by providing multiple supporting rods 21, the lifting tray 2 can have better article bearing performance and prevent small-sized articles from falling. Alternatively, multiple mounting seats 10 are provided at the bottom of the side longitudinal beam 12, so that the fixing frame 1 can be fixed to the floor at the bottom of the trunk through the mounting seats 10. Multiple mounting seats 10 are provided at the bottom of the fixing frame 1, and the fixing frame 1 can be conveniently fixed to the floor at the bottom of the trunk by using the mounting holes on the mounting seats 10.

[0044] There are of course multiple driving forms for the driving unit. In the present embodiment, the driving unit includes a motor 30 disposed on the fixed frame 1, and a pull wire 300 driven by the motor 30; the pull wire 300 can be arranged in the guide groove 120 on the side longitudinal beam 12, and the end of the pull wire 300 is connected to the lifting tray 2; driven by the motor 30, the pull wire 300 can pull the lifting tray 2 to move upward. The driving unit is driven by the motor 30, which has the characteristics of easy drive control and stable driving performance. In actual application, the end of the pull wire 300 can be fixedly connected to the lifting tray 2. When the motor 30 retracts the pull wire 300, the pull wire 300 pulls the lifting tray 2 to realize the lifting action of the lifting tray 2; when the lifting tray 2 descends, it can be realized by its own gravity, and the pulling force of the pull wire 300 can be used to control the descending speed of the lifting tray 2. At the same time, the pull wire 300 can be divided into two wires respectively connected to the guide seats 310, and the pull wire 300 can be used to slide the two guide seats 310 by setting a steering wheel and other structures at the end of the side longitudinal beam 12; in this way, the driving effect of the horizontal guiding movement of the lifting tray 2 relative to the fixed frame 1 can be achieved by using the driving unit.

[0045] To sum up, the trunk item loading and unloading device of the present embodiment is provided with a lifting tray 2 that can move forward and backward on a fixed frame 1. When it is necessary to move or unload items, the lifting tray 2 can be moved to a second position outside the trunk, and can be lifted or lowered under the drive of a driving unit to move items into the trunk or take them out of the trunk, thereby providing an auxiliary loading and unloading device for items and cargo in the trunk.

[0046] Embodiment 2

[0047] This embodiment relates to a vehicle, in which the trunk of the vehicle is provided with the trunk article loading and unloading device provided in the first embodiment.

[0048] In daily use, there are two situations: placing items in the trunk and taking items out of the trunk.

[0049] In the case of placing items in the trunk, first open the back door of the vehicle, pull the lifting tray 2 from the first position above the fixed frame 1 to the second position outside the trunk, or use the vehicle's central console to control the driving action of the motor 30, and drive the guide seat 310 to move horizontally through the pull wire 300 to achieve the movement of the lifting tray 2 between the first position and the second position. When the lifting tray 2 reaches the second position, control the pulling force of the pull wire 300 so that the lifting tray 2 drops to the ground at a steady speed under the action of its own gravity, and then place the items on the lifting tray 2. Then control the pull wire 300 to pull the lifting tray 2 up, and when it reaches the height opposite the fixed frame 1, the lifting tray 2 can be manually pushed into the trunk (or the pull wire 300 is used to pull and drive the lifting tray 2 to move) and return to the first position. Finally, close the back door.

[0050] In the case of taking out items from the trunk, the action control process is opposite to the loading process. First, the back door is opened, and the lifting tray 2 moves from the first position to the second position, and then the lifting tray 2 is lowered to the ground. After the items on the lifting tray 2 are removed, the control line 300 pulls the lifting tray 2 up to the height of the fixing frame 1, and then the lifting tray 2 is pushed back to the first position. Finally, the back door is closed.

[0051] From the above usage process, it can be seen that the setting of the trunk item loading and unloading device in the trunk solves the pain point of customers' difficulty in carrying items and improves the product competitiveness of the vehicle; moreover, the trunk item loading and unloading device can be set at the bottom of the trunk, which occupies a small space and is easy to use; it can be conveniently controlled through the center console of the cab or a separately set control switch.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
