[0028] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention.

[0029] Reference Figure 1 This embodiment provides a lifting mechanism, including a lifting unit 1 and a support unit 2.

[0030] Preferably, the lifting unit 1 includes a chassis 11, a drive member 12 mounted on the chassis 11, the telescopic portion of the drive member 12 rising upwards, support arm assemblies 13 symmetrically arranged on both sides of the chassis 11, the support arm assemblies 13 changing angle during lifting, the drive member 12 and the support arm assemblies 13 being movably connected by a connector 14, that is, when the drive member 12 lifts, the connector 14 moves on the support arm assemblies 13, and a slider 15 movably connected to the support arm assemblies 13, the slider 15 moving horizontally. The support unit 2 includes a telescopic member 21 mounted on the chassis 11, the telescopic member 21 and the drive member 12 being fixedly positioned, the telescopic member 21 being fixedly mounted to the top, and the slider 15 sliding to the top when the support arm assemblies 13 change angle. The telescopic member 21 is the same device as the drive member 12, such as a hydraulic rod.

[0031] In use, the telescopic component 21 and the driving component 12 are fixed in position. The telescopic component 21 is fixedly set to the top. When the driving component 12 lifts or lowers, it causes the connecting component 14 to move on the support arm assembly 13. The support arm assembly 13 changes angle during the lifting or lowering process. The support arm assembly 13 is also movably connected to the slider 15. The slider 15 slides horizontally with the top. Since the telescopic action of the driving component 12 directly drives the connecting component 14 to slide on the support arm assembly 13, the lifting or lowering function is realized. This ensures the stability of the lifting or lowering process and avoids the shaking or damage of goods caused by unstable movement.

[0032] Reference Figures 1-5 As an optional embodiment, the chassis 11 includes a first base platform 111, a second base platform 112, a third base platform 113, a first limiting groove 114, and a first connecting shaft 115. The first base platform 111 is disposed on the chassis 11 and is used to limit the drive member 12. The second base platform 112 is disposed on both sides of one end of the chassis 11. The third base platform 113 is disposed between the first base platform 111 and the second base platform 112. The first limiting groove 114 is disposed on both sides of the other end of the chassis 11 and is used to limit the telescopic member 21. The first connecting shaft 115 is disposed on the bottom side of the chassis 11 and is used to install a wheel set at the bottom of the chassis 11.

[0033] Furthermore, a second connecting shaft 1111 is provided between the first base platforms 111, and the driving member 12 is movably connected to the second connecting shaft 1111. In this embodiment, the driving member 12 is vertically arranged on the chassis 11 through the second connecting shaft 1111. A first connecting hole 1121 is provided on the second base platform 112, and a second connecting hole 1131 is provided on the third base platform 113.

[0034] Preferably, the support arm assembly 13 includes a first support arm 131 and a second support arm 132, with the first support arm 131 and the second support arm 132 being hingedly connected.

[0035] Furthermore, the first support arm 131 includes a third connecting hole 1311 and a fourth connecting hole 1312 disposed at both ends, and the second support arm 132 includes a convex groove 1321 disposed on the side wall and a fifth connecting hole 1322 and a sixth connecting hole 1323 disposed at both ends. The opening of the convex groove 1321 on the side wall of the second support arm 132 is smaller than the diameter of the internal groove of the second support arm 132.

[0036] Furthermore, the first support arm 131 is fixedly mounted on the chassis 11 via the first connecting hole 1121, the seventh connecting hole 1311, the fourth connecting hole 1312, and the second connecting hole 1131. The first support arm 131 is positioned between the second base platform 112 and the third base platform 113, so that the second support arm 132 is more stable when the first support arm 131 is hinged to the second support arm 132. The second support arm 132 is hinged to the first support arm 131 via the sixth connecting hole 1323, the fourth connecting hole 1312, and the second connecting hole 1131.

[0037] Preferably, the connector 14 includes a connecting rod 141 and a connecting block 142. The connecting block 142 is disposed at both ends of the connecting rod 141. The connecting block 142 is slidably connected to the convex groove 1321. The connecting block 142 slides on the second support arm 132 and is not easy to fall off. When the connector 14 rises and falls with the drive member 12, it slides in the convex groove 1321, causing the second support arm 132 to change angle.

[0038] Preferably, the slider 15 includes a limiting block 151 and a slider connecting hole 152. The limiting block 151 is disposed at the top of the slider 15 and slides within the limiting groove. The slider 15 is hinged to the second support arm 132 through the slider connecting hole 152 and the fifth connecting hole 1322.

[0039] In use, the telescopic component 21 and the driving component 12 are fixed in position. The driving component 12 is vertically mounted on the chassis 11 via the second connecting shaft 1111. The first support arm 131 is fixedly mounted on the chassis 11 and is positioned between the second base platform 112 and the third base platform 113. The second support arm 132 is hinged to the first support arm 131. The connecting component 14 rises and falls with the driving component 12. The connecting block 142 slides within the convex groove 1321, causing the second support arm 132 to change angle. The slider 15 is hinged to the second support arm 132. The limiting block 151 is located at the top of the slider 15 and slides within the limiting groove, thus making the driving component 12 more stable during the rising and falling process. When the center lines of the slider 15 and the driving component 12 are on the same vertical line, the driving component 12, the first support arm 131, and the second support arm 132 form a right triangle A. At this time, the driving component 12 supports... The best support effect is achieved by ensuring that the drive component 12 remains stable during lifting, providing sufficient support and preventing structural deformation or damage due to insufficient support. The connection between the drive component 12 and the support arm assembly 13 (sliding connection through connectors and convex grooves) effectively distributes the force, allowing the entire lifting mechanism to remain stable even under heavy loads. Furthermore, the vertically arranged drive component 12 has a relatively simple structure, and its working principle and movement are intuitive, making it easy to install and maintain. Compared to complex cross-lifting structures, this design reduces the number and complexity of mechanical parts, lowers the probability of failure, and simplifies the maintenance of the drive component 12, requiring only periodic checks of the hydraulic oil level and sealing. In this embodiment, the lifting mechanism, especially for the switch truck, has its center of gravity biased to one side, so telescopic components 21 are symmetrically arranged below the biased side of the switch truck.

[0040] Reference Figures 1 to 8 As an optional embodiment, the trolley unit 3 includes a wheel assembly 31 and a mounting platform 32. The wheel assembly 31 is mounted on the bottom side of the chassis 11 via a first connecting shaft 115. The limiting block 151 is slidably connected to the mounting platform 32, and the telescopic member 21 is movably connected to the mounting platform 32. In this embodiment, the wheel assembly 31 can move at any angle, and the foot lock can be controlled by wireless signal in the prior art. By setting a drive motor and a control module on the chassis 11, the trolley can move on its own.

[0041] Preferably, the placement platform 32 includes a fourth base 321, a second limiting groove 322, and a guardrail 323. The telescopic member 21 is movably connected to the fourth base 321 through a seventh connecting hole 3211. The limiting block 151 is slidably connected to the second limiting groove 322. The guardrail 323 is set on the top side of the placement platform 32, wherein the height of the guardrail 323 is preferably 4~6cm.

[0042] When in use, the complete switchgear is moved horizontally onto the mounting platform 32. The guardrail 323 can prevent the complete switchgear from falling off the mounting platform 32, and the guardrail 323 does not obstruct the operator's operation. The wheel assembly 31 can move at any angle, which makes it easier for the trolley to move the complete switchgear.

[0043] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
