Description

Technical Field

[0001] The utility model relates to the technical field of logistics vehicles, in particular to a flip mechanism test bench. Background Art

[0002] With the development of the logistics industry, unmanned logistics vehicles are transporting an increasing amount of cargo. To enable automated loading and unloading of cargo, existing unmanned logistics vehicles are typically equipped with a flipping mechanism at the rear of the vehicle. During loading, the flipping mechanism first flips the load-bearing frame from a vertical unloading position to a horizontal position, then moves the load-bearing frame a certain distance toward the front of the vehicle until it reaches the horizontal transport position. During unloading, the flipping mechanism first moves the load-bearing frame from the horizontal transport position to a certain distance toward the rear of the vehicle, then flips the load-bearing frame from the horizontal position to the vertical unloading position.

[0003] To ensure the smooth and stable operation of the flip mechanism, it is necessary to conduct functional and durability tests on the flip mechanism. In the existing technology, the flip mechanism is usually mounted on a real vehicle for testing. However, this can easily cause damage to the vehicle itself during the testing process, especially for the flip mechanism still in the development stage.

[0004] Therefore, there is an urgent need for a flip mechanism test bench to solve the above technical problems. Utility Model Content

[0052] like Figures 1 to 5 As shown, this embodiment provides a flip mechanism test bench for installing a flip mechanism 100 to test the flip mechanism 100. The flip mechanism 100 of this embodiment is connected to a load-bearing frame 200 and can drive the load-bearing frame 200 to move between a horizontal transport state and a vertical unloading state. The load-bearing frame 200 is used to load a cargo box 300. Specifically, when the load-bearing frame 200 is in the vertical unloading state, the flip mechanism 100 can first drive the load-bearing frame 200 to flip forward to a horizontal state, and then drive the load-bearing frame 200 to translate a certain distance toward the front end of the test bench until it reaches the horizontal transport state; when the load-bearing frame 200 is in the horizontal transport state, the flip mechanism 100 can first drive the load-bearing frame 200 to translate a certain distance toward the rear end of the test bench, and then drive the load-bearing frame 200 to flip backward to the vertical unloading state.

[0053] refer to Figure 1-Figure 2The flipping mechanism 100 of this embodiment includes a driving workstation 101, a first telescopic member bracket 102, a first telescopic member 103, a second telescopic member bracket 104, a second telescopic member 105, a linear slide 106, a slide 107, a first guide frame 108, a second guide frame 109 and a rotating shaft 110. The driving workstation 101 is fixed on the test bench and is used to control the operation of the first telescopic member 103 and the second telescopic member 105. Preferably, the first telescopic member 103 and the second telescopic member 105 of this embodiment are both hydraulic cylinders, and the driving workstation 101 is a hydraulic station. The first telescopic member bracket 102 is fixed on the test bench, one end of the first telescopic member 103 is hinged to the first telescopic member bracket 102, and the other end is hinged to the second telescopic member bracket 104, and the first telescopic member 103 can be extended and retracted along a first direction. Specifically, the first direction of this embodiment is the front-to-back direction of the test bench (that is, representing the front-to-back direction of the logistics vehicle body). A linear slide 106 is fixed to the test bench and extends in a first direction. A slider is slidably connected to the linear slide 106, and a slide plate 107 is fixed to the slider. The second telescopic member bracket 104 is fixed to the slide plate 107. This arrangement allows the telescopic movement of the first telescopic member 103 to drive the slide plate 107 to slide in the first direction. One end of the second telescopic member 105 is hinged to the second telescopic member bracket 104, and the other end is hinged to the support frame 200, used to drive the support frame 200 to rotate. A first guide frame 108 and a second guide frame 109 are respectively fixed to the test bench and located on either side of the second telescopic member 105. Both the first guide frame 108 and the second guide frame 109 extend in the first direction and are internally provided with guide grooves extending in the first direction. A rotating shaft 110 is rotatably connected to the bottom of the support frame 200 via bearings. Both ends of the rotating shaft 110 are movably mounted within the guide grooves of the first guide frame 108 and the second guide frame 109. In this embodiment, the first telescopic member 103 and the second telescopic member 105 are arranged in sequence along the first direction, and the telescopic directions of the first telescopic member 103 and the second telescopic member 105 are located in the same vertical plane. With this arrangement, only two driving members are needed to realize the switching of the carrying frame 200 between the horizontal transportation state and the vertical unloading state, which is beneficial to saving the number of telescopic members, saving installation space, and reducing costs. In addition, it is easier to control the two telescopic members, ensuring the smooth progress of the loading and unloading process and preventing the mechanism from getting stuck.

[0054] refer to Figure 3-Figure 5The flipping mechanism test bench provided in this embodiment includes a frame body 1, a workstation mounting plate 2, a first support structure 3, a second support structure 4 and a third support structure 5. The frame body 1 includes a bottom frame, a top frame and a plurality of columns 10 connected between the bottom frame and the top frame, wherein the top frame is used to simulate the chassis platform of the vehicle body. The workstation mounting plate 2 is fixed on the top frame and close to the front end of the frame body 1, and is used to install the drive workstation 101. The first support structure 3 is arranged on the top frame and is located on the rear side of the workstation mounting plate 2, and is used to install the first telescopic member bracket 102. The second support structure 4 is arranged on the top frame and the bottom frame, and is located on the rear side of the first support structure 3, and is used to install a linear slide rail 106 extending along the first direction. The third support structure 5 is arranged on the top frame and close to the rear end of the frame body 1, and is used to install a first guide frame 108 and a second guide frame 109 extending along the first direction.

Furthermore, the bottom frame of this embodiment includes a third crossbeam 15, a third longitudinal beam 16, a fourth crossbeam 17, and a fourth longitudinal beam 18 that are connected end to end in the same horizontal plane to form a rectangular frame.

A number of columns 10 are fixedly connected between the first longitudinal beam 12 and the third longitudinal beam 16, and between the second longitudinal beam 14 and the fourth longitudinal beam 18. The top frame, bottom frame, and columns 10 together form a rectangular frame body 1, which features a simple structure and excellent support, ensuring the stability of the test bench during operation. For example, in this embodiment, four columns 10 are provided between the first and third longitudinal beams 12, 16, and four columns 10 are provided between the second and fourth longitudinal beams 14, 18, to ensure good support for the top frame.

[0057] Optionally, the first support structure 3 of this embodiment includes a first crossbar 31, a second crossbar 32, and a third crossbar 33 fixedly connected between the first longitudinal beam 12 and the second longitudinal beam 14.

A telescopic member bracket mounting plate 34 is fixed between the first crossbar 31 and the second crossbar 32 for mounting the first telescopic member bracket 102. Since the first telescopic member 103 telescopes in the first direction, to improve the support performance of the first telescopic member 103, a first longitudinal bar 35 is further fixed between the second crossbar 32 and the third crossbar 33 of this embodiment. The first longitudinal bar 35 extends in the first direction. This arrangement effectively ensures the stability of the test bench and prevents deformation during the telescopic process of the first telescopic member 103.

[0058] Optionally, the second supporting structure 4 of this embodiment includes an upper support, a lower support, and a plurality of supporting columns 40 connected between the upper support and the lower support. Specifically, the upper bracket includes a fourth cross bar 41, a fifth cross bar 42, a sixth cross bar 43, a second longitudinal bar 44 and a third longitudinal bar 45, wherein the fourth cross bar 41 and the fifth cross bar 42 are respectively connected between the first longitudinal beam 12 and the second longitudinal beam 14, and the fourth cross bar 41 and the fifth cross bar 42 both extend along the second direction; the second longitudinal bar 44 and the third longitudinal bar 45 are respectively connected between the fourth cross bar 41 and the fifth cross bar 42, and the second longitudinal bar 44 and the third longitudinal bar 45 both extend along the first direction, and the second longitudinal bar 44 and the third longitudinal bar 45 are respectively used to fix the linear slide rail 106 extending along the first direction; the sixth cross bar 43 is connected between the first longitudinal beam 12 and the second longitudinal beam 14, the sixth cross bar 43 extends along the second direction, and is supported below the second longitudinal bar 44 and the third longitudinal bar 45 to improve the supporting performance of the linear slide rail 106. The lower support structure includes a seventh crossbar 46, an eighth crossbar 47, a fourth longitudinal bar 48, and a fifth longitudinal bar 49. The seventh crossbar 46 and the eighth crossbar 47 are connected between the third longitudinal beam 16 and the fourth longitudinal beam 18, respectively, and both extend in the second direction. The fourth longitudinal bar 48 and the fifth longitudinal bar 49 are connected between the seventh crossbar 46 and the eighth crossbar 47, respectively, and both extend in the first direction. Because the second support structure 4 needs to support components such as the linear guide rail 106, the slide 107, the second telescopic member bracket 104, and the second telescopic member 105, this embodiment improves the strength of the second support structure 4 by providing multiple crossbars, longitudinal bars, and support columns 40, thereby ensuring the movement reliability of the flip mechanism 100.

[0059] Optionally, the third support structure 5 includes at least two first guide frame mounting plates 51 and at least two second guide frame mounting plates 52.

The ninth crossbar 61 extends in the second direction, and the two ends of the ninth crossbar 61 are fixedly connected to the two columns 10 on the rear side of the frame body 1. A limiting buffer 62 is provided at the rear end of the ninth crossbar 61. The limiting buffer 62 is used to abut against the load-bearing frame 200 when it moves to the vertical unloading state. The limiting buffer 62 can buffer the collision between the load-bearing frame 200 and the rear end of the test bench (equivalent to the rear end of the vehicle body) during the flipping process, thereby forming an effective safety protection; and the limiting buffer 62 can play an extreme position limiting role in the flipping movement of the load-bearing frame 200, thereby improving the position accuracy of the flipping of the load-bearing frame 200. Preferably, the limiting buffer 62 includes a buffer block and a buffer block mounting seat. The buffer block mounting seat is fixed to the ninth crossbar 61, and the buffer block is mounted on the buffer block mounting seat. The material of the buffer block in this embodiment can be rubber, plastic, foam, etc., to achieve the effect of buffering collision force. In addition, an inclined reinforcing rod 63 is fixedly connected between the eighth cross bar 47 and the ninth cross bar 61. One end of the reinforcing rod 63 corresponds to the position of the limiting buffer 62.
