Description

Technical Field

[0001] This utility model belongs to the field of vehicle auxiliary equipment technology, and more specifically, it relates to a hydraulic platform for the rear of a vehicle with storage function. Background Technology

[0002] In logistics, transportation, and freight distribution industries, vehicle rear-end platforms are widely used auxiliary equipment. Their core function is to facilitate efficient loading and unloading of goods, significantly reducing the labor intensity of manual handling and bringing substantial convenience to related operations.

[0003] Based on the above, traditional vehicle rear platforms are mostly single tailgate structures with limited functionality, only playing an auxiliary role in loading and unloading cargo. Although some tailgates have storage boxes welded on, this fixed connection method makes the storage boxes impossible to remove. When the storage boxes are damaged and need repair or replacement, the disassembly process is cumbersome, requiring cutting the welded joints, which is not only time-consuming and labor-intensive, but may also damage the tailgate itself.

[0037] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0038] Example 1: As Figures 1 to 5 As shown, the vehicle rear hydraulic platform with storage function provided by this utility model includes: a cargo box 1 and an installation structure 2; a tail plate 101 is provided on the rear side of the cargo box 1, and the installation structure 2 is provided on the tail plate 101.

[0039] The mounting structure 2 includes a fixed protrusion 201, a movable belt block 202, and a storage back box 203. The fixed protrusion 201 is fixedly connected to the four sides of the tail plate 101. A guide slide rod 2011 is fixedly connected between the fixed protrusions 201. A two-way screw rod 2012 is provided at the front end of the guide slide rod 2011. One end of the two-way screw rod 2012 passes through the fixed protrusion 201 and is fixedly connected to the connecting protrusion 2013. A hexagonal groove 2014 is provided on the connecting protrusion 2013.

[0040] The movable belt block 202 is located between the fixed protrusions 201. The movable belt block 202 has a threaded hole 2021 and a guide hole 2022. A locking plug 2023 is fixedly connected to one end of the inner side of the movable belt block 202. The storage back box 203 is located on the rear side of the tail plate 101. A connecting protrusion frame 2031 is fixedly connected to the four sides of the storage back box 203. A locking slot 2032 is provided on the opposite side of the connecting protrusion frame 2031. The locking plug 2023 is fitted into the locking slot 2032.

[0041] In this embodiment, the storage back box 203 is positioned on the tail plate 101, and then inserted into the hexagonal groove 2014 with the help of external tools, which drives the connecting cam 2013 to rotate. The connecting cam 2013 drives the bidirectional lead screw 2012 to rotate. The bidirectional lead screw 2012 rotates and engages with the threaded hole 2021 on the moving block 202. However, the moving block 202 is limited and guided on the guide slide rod 2011 through the guide hole 2022, so that the bidirectional lead screw 2012 drives the two sets of moving blocks 202 to move in opposite directions. Thus, the moving block 202 drives the locking insert 2023 to move and insert into the locking slot 2032, thereby completing the installation of the storage back box 203.

[0042] Example 2: Based on Example 1, wherein, as Figure 4 and Figure 5 As shown, the bottom of the box cargo 1 is provided with a flip adjustment assembly 3. The flip adjustment assembly 3 includes a connecting support plate 301 and a first hydraulic cylinder 302. The bottom of the box cargo 1 is provided with a connecting support plate 301. The front end of the connecting support plate 301 is fixedly connected with a first hinge 3011, and the bottom of the tail plate 101 is fixedly connected with a second hinge 3013. The first hinge 3011 is hinged to both ends of the first hydraulic cylinder 302 through a first shaft pin 3012 and the second hinge 3013 through a second shaft pin 3014.

[0043] Two sets of fixed hinge plates 303 are provided between the second hinge frame 3013. A third shaft pin 3031 is provided between the fixed hinge plate 303 and the second hinge frame 3013. A connecting bushing 3032 is provided on the outside of the third shaft pin 3031. A fixed hinge block 3033 is fixedly connected to the outside of the connecting bushing 3032. One end of the fixed hinge block 3033 is fixedly connected to the connecting rod 3034.

[0044] The bottom of the connecting rod 3034 is provided with a third hinge 3036, and a fourth pin 3037 is provided on the third hinge 3036. One end of the connecting rod 3034 is fixedly connected to the connecting rod 3035, and the other end of the connecting rod 3035 is hinged to the double-sided hinge 304 via a sixth pin 3042. The double-sided hinge 304 is also provided with a fifth pin 3041, and the double-sided hinge 304 is hinged to both ends of the second hydraulic cylinder 305 via the fifth pin 3041 and the third hinge 3036 via the fourth pin 3037, respectively.

[0045] In this embodiment, when the first hydraulic cylinder 302 is activated to retract, the tail plate 101 can be driven to complete the flipping action through the transmission structure. After flipping to a preset angle, the second hydraulic cylinder 305 is activated to retract, and its power is transmitted to the tail plate 101 through the connecting rod 3035, causing the tail plate 101 to gradually descend until it lands smoothly, meeting the basic requirements for loading and unloading goods. Conversely, if the tail plate 101 needs to be retracted, the second hydraulic cylinder 305 can be controlled to extend first. Under the linkage of the connecting rod 3035, the tail plate 101 rises until it reaches a horizontal state. Then, the first hydraulic cylinder 302 is activated to extend it, and the thrust pushes the tail plate 101 to continue flipping, eventually causing the tail plate 101 to gradually transition from a horizontal state to a vertical state, closely fitting the rear of the vehicle, reducing space occupation, and ensuring the safety and convenience of the vehicle during driving.

[0046] In this invention, the storage back box 203 is positioned on the tail plate 101, and then inserted into the hexagonal groove 2014 using an external tool, causing the connecting cam 2013 to rotate. The connecting cam 2013 drives the bidirectional lead screw 2012 to rotate, and the bidirectional lead screw 2012 engages with the threaded hole 2021 on the moving belt block 202. However, the moving belt block 202 is limited and guided on the guide slide rod 2011 through the guide hole 2022, so that the bidirectional lead screw 2012 drives the two sets of moving belt blocks 202 to move in opposite directions. As a result, the moving belt blocks 202 drive the locking insert 2023 to move and insert into the locking slot 2032, thus completing the installation of the storage back box 203, eliminating the need for traditional welding installation. This design allows for flexible disassembly of the storage box. When damage occurs and repair or replacement is needed, there is no need to cut the welding points; it can be easily removed with simple operations, greatly simplifying the disassembly process and saving time and labor costs. Secondly, it avoids the risk of damage to the tail plate body caused by cutting the welding points, effectively protecting the structural integrity and service life of the tail plate. When flipping, the first hydraulic cylinder 302 is activated to retract it, which drives the tail plate 101 to complete the flipping action through the transmission structure. After flipping to the preset angle, the second hydraulic cylinder 305 is activated to retract it. Its power is transmitted to the tail plate 101 through the connecting rod 3035, causing the tail plate 101 to gradually descend until it lands smoothly on the ground, meeting the basic requirements for loading and unloading goods.
