Description

Technical Field

[0001] This application relates to the technical field of automobile repair, and in particular to a lifting platform vehicle for replacing new energy batteries. Background Technology

[0002] A lifting platform truck is a mobile mechanical device used to lift tools and materials to a specified height for operation. It is widely used in warehousing, logistics, manufacturing and other fields.

[0003] Currently, the industry commonly uses foot-operated scissorless lifting platform trucks. These trucks consist of a movable support base, a lifting platform mounted on top of the base, and a foot-operated hydraulic pump that drives the platform's movement. The operator repeatedly presses the pedal of the hydraulic pump to force hydraulic oil into the cylinder, which in turn pushes the piston rod upward, raising the lifting platform. Foot-operated lifting platform trucks are also equipped with a pressure relief valve. By rotating or actuating the valve, the hydraulic oil slowly flows back to the tank under the weight of the lifting platform, allowing it to descend smoothly.

[0004] For the technologies mentioned above, when replacing new energy batteries, it is often necessary to frequently and precisely adjust the height of the lifting platform to adapt to the needs of different vehicle models and battery locations. Foot-operated lifting platform vehicles require the operator to repeatedly step on the pedals, using a hydraulic pump to pressurize hydraulic oil into the cylinder to raise the platform. This process is not only time-consuming and labor-intensive but also inefficient. Utility Model Content

[0005] To improve the efficiency of new energy battery replacement, this application provides a lifting platform vehicle for new energy battery replacement.

[0006] The lifting platform vehicle for swapping new energy batteries provided in this application adopts the following technical solution: A lifting platform vehicle for swapping new energy batteries includes a platform vehicle body and a lifting mechanism. The lifting mechanism includes a drive source disposed on a support base for providing power, a drive component disposed on one side of the output end of the drive source for injecting and withdrawing hydraulic oil, and a drive cylinder for raising the lifting platform. The support base is provided with a control handle, and the end of the control handle is provided with a lift button for controlling the injection of hydraulic oil into the drive component and a lower button for controlling the withdrawal of hydraulic oil from the drive component.

[0007] By adopting the above technical solution, the drive source provides power to the lifting mechanism, and the drive components inject and withdraw hydraulic oil to drive the drive cylinder to raise or lower the lifting platform. The raise and lower buttons at the end of the control handle facilitate the operator's control of the platform vehicle's raising and lowering.

[0008] Optionally, the drive unit includes an oil reservoir for storing hydraulic oil and a gear pump for driving the injection or extraction of hydraulic oil.

[0009] By adopting the above technical solution, hydraulic oil is stored in an oil tank to provide a sufficient supply of hydraulic oil for driving the hydraulic cylinder, ensuring the normal lifting and lowering of the lifting platform; a gear pump is used to drive the injection or extraction of hydraulic oil, which can effectively control the flow of hydraulic oil and precisely adjust the lifting action of the lifting platform.

[0010] Optionally, an electric pulley is installed at the lower end of the control handle, the electric pulley including a sliding wheel and a drive motor for driving the sliding wheel to rotate.

[0011] By adopting the above technical solution, an electric pulley is installed at the lower end of the control handle of the lifting platform vehicle, which makes it easier to move the lifting platform vehicle under the control of the control handle, thereby improving its flexibility and convenience of movement.

[0012] Optionally, the end of the control handle away from the electric pulley is provided with a forward button for controlling the rotation of the electric pulley and a reverse button for controlling the rotation of the electric pulley.

[0013] By adopting the above technical solution, the control handle is equipped with forward and reverse buttons at the end away from the electric pulley, which can control the rotation of the electric pulley to achieve forward and reverse movement, making it convenient for operators to control the movement of the platform vehicle.

The leg unit has an extension that inserts into the support sleeve. The outer surface of the extension has an external thread, and the inner side of the support sleeve has an internal thread that mates with the external thread.

[0015] By adopting the above technical solution, a support leg is set on the side of the support base of the lifting platform vehicle facing the control handle. The support leg unit is engaged with the internal thread of the support sleeve rod through external thread, which can adjust the depth of the support leg unit inserted into the support sleeve rod, thereby adjusting the length of the support leg, which plays a role in stabilizing the main body of the lifting platform vehicle and improving the stability of the lifting platform vehicle during use.

[0016] Optionally, the support base is equipped with a dust cover for protecting the drive source and the drive components from dust; one end of the dust cover has an opening for wiring to pass through.

[0017] By adopting the above technical solution, a dust cover can be installed on the support base to prevent dust from entering the drive source and drive components, reducing the impact of dust on their performance and service life; one end of the dust cover is provided with an opening for the wiring to pass through, which facilitates the wiring layout and connection.

[0021] By adopting the above technical solution, the ball spring plunger is installed on the bottom surface of the mounting groove, and the dust cover has a snap-fit ​​groove that mates with the ball spring plunger. This allows the dust cover to be stably installed on the mounting guide rail of the support base. At the same time, the fit between the ball spring plunger and the snap-fit ​​groove facilitates the positioning of the dust cover, making it less prone to shaking and displacement when the lifting platform vehicle moves, thus ensuring that the dust cover can effectively protect the drive source and drive components from dust.

[0022] Optionally, the number of ball spring plungers is two, and the two ball spring plungers are arranged horizontally.

[0023] By adopting the above technical solution, when installing or disassembling the drive source and drive components, the sliding dust cover exposes the installation position of the drive source and drive components, and the corresponding ball head spring plunger is embedded in the snap-fit ​​groove, which can position the dust cover and reduce the probability of the dust cover sliding due to external force, thus affecting the installation of the drive source and drive components.

[0024] Optionally, the dust cover is provided with an operating handle on its side wall.

[0025] By adopting the above technical solution, an operating handle is provided on the side wall of the dust cover, which facilitates the sliding of the dust cover.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a lifting platform vehicle for swapping new energy batteries. (Refer to...) Figure 1The lifting platform vehicle used for swapping new energy batteries includes a platform vehicle body 1 and a lifting mechanism. The platform vehicle body 1 includes a movable support base 11, a lifting platform 12 installed on top of the support base 11, and a lifting assembly 13 movably installed between the support base 11 and the lifting platform 12.

[0037] Reference Figure 1 and Figure 2 The lifting assembly 13 includes at least two sets of cross lifting arms 131, which are symmetrically arranged. In this embodiment, the lifting assembly 13 includes two sets of cross lifting arms 131, each comprising an inner lifting arm 1311 and an outer lifting arm 1312. The lower end of the inner lifting arm 1311 is rotatably connected to the support base 11, and the upper end of the inner lifting arm 1311 is slidably connected to the bottom of the lifting platform 12. The upper end of the outer lifting arm 1312 is rotatably connected to the lifting platform 12, and the lower end of the outer lifting arm 1312 is slidably connected to the top of the support base 11.

[0038] Reference Figure 2 and Figure 3 The lifting mechanism includes a drive source 21 mounted on the support base 11 for providing power, a drive assembly located on one side of the output end of the drive source 21 for injecting and withdrawing hydraulic oil, and a drive cylinder 23 for lifting the lifting platform 12. In this embodiment, the lower ends of the two sets of outer lifting arms 1312 are provided with interconnected connecting rods 1316, and the drive cylinder 23 is mounted on the connecting rods 1316; a connecting shaft 1315 is provided at the rotatable connection between the inner lifting arm 1311 and the outer lifting arm 1312, and the output shaft end of the drive cylinder 23 is connected to the connecting shaft 1315. The drive source 21 and the drive assembly are mounted on the support base 11.

[0039] Reference Figure 3 The drive assembly includes an oil reservoir 221 for storing hydraulic oil and a gear pump 222 for driving the injection or extraction of hydraulic oil. The oil reservoir 221 and the gear pump 222 are connected by a pipeline. Driven by the drive source 21, the gear pump 222 can extract the hydraulic oil in the oil reservoir 221 and inject it into the drive cylinder 23 through the pipeline to realize the lifting action of the lifting platform 12. When it is necessary to lower the lifting platform 12, the gear pump 222 rotates in reverse to draw the hydraulic oil in the drive cylinder 23 back to the oil reservoir 221, so that the lifting platform 12 descends smoothly.

[0040] Reference Figure 1 and Figure 3 The support base 11 is equipped with a dust cover 3 for protecting the drive source 21 and drive components from dust. One end of the dust cover 3 has an opening for wiring to pass through.

[0041] Reference Figure 3 and Figure 4The support base 11 has a pair of mounting rails 112 arranged parallel to each other on both sides of the drive source 21 and the drive assembly. Each mounting rail 112 has a mounting groove 1121 that mates with the dust cover 3. The two side edges of the dust cover 3 have mating parts 33 that slide and engage with the mounting groove 1121. In this embodiment, the mounting groove 1121 has a T-shaped cross-section, and the mounting rails 112 are mounted to the support base 11 with screws.

[0042] Reference Figure 4 and Figure 5 To further improve installation stability, a ball-head spring plunger 1122 is provided on the bottom surface of the mounting groove 1121, and a corresponding snap-fit ​​groove 31 is provided on the dust cover 3 to cooperate with the ball-head spring plunger 1122. The ball-head spring plunger 1122 includes a plunger housing 1123, a plunger ball 1124 installed inside the plunger housing 1123, and a plunger spring 1125 installed inside the plunger housing 1123 to support the plunger ball 1124. When the dust cover 3 is pushed into the set position along the mounting groove 1121, the plunger ball 1124 is embedded in the snap-fit ​​groove 31, realizing the positioning and locking of the dust cover 3. In this embodiment, there are two ball-head spring plungers 1122, and the two ball-head spring plungers 1122 are arranged horizontally.

[0043] Reference Figure 1 and Figure 5 The dust cover 3 is also equipped with an operating handle 32 on its side wall. The operating handle 32 is ergonomically designed with a non-slip surface, allowing the operator to easily grip it and apply pushing or pulling force to make the dust cover 3 slide smoothly along the mounting guide rail 112. When maintenance is required on the drive source 21 or drive components, simply grip the operating handle 32 and pull it laterally to move the dust cover 3 smoothly. When the internal components are exposed, the corresponding plunger ball head on the mounting slide groove 1121 engages in the locking groove 31. After maintenance is completed, grip the handle again to push the dust cover 3 back to its original position until the plunger ball head engages in the corresponding locking groove 31, ensuring that the dust cover 3 is securely installed.

[0044] Reference Figure 1 and Figure 6 The support base 11 is provided with a control handle 4. The end of the control handle 4 is provided with a lifting button for controlling the injection of hydraulic oil into the drive component and a lowering button for controlling the withdrawal of hydraulic oil from the drive component.

[0045] Reference Figure 6 and Figure 7An electric pulley 5 is mounted on the lower end of the control handle 4. The electric pulley 5 includes a sliding wheel 51 and a drive motor 52 that drives the sliding wheel 51 to rotate. A forward button for controlling the rotation of the electric pulley 5 and a reverse button for controlling the rotation of the electric pulley 5 are provided on the end of the control handle 4 away from the electric pulley 5. Operating handles 41 are also provided on both sides of the control handle 4.

[0046] Reference Figure 1 and Figure 7 An adjustable-height support leg 6 is provided on the side of the support base 11 facing the control handle 4, and a rolling pulley 7 is provided on the side away from the control handle 4. The support leg 6 consists of a support sleeve 61 and a leg unit 62. The leg unit 62 has an extension 621 that inserts into the support sleeve 61. The outer surface of the extension 621 has external threads, and the inner surface of the support sleeve 61 has internal threads that mate with the external threads. By rotating the leg unit 62, its insertion depth into the support sleeve 61 can be adjusted, thereby adjusting the overall length of the support leg 6. When the lifting platform vehicle is stationary, rotating the leg unit 62 adjusts the height of the support leg 6, ensuring that the support leg 6 is stably supported on the ground, guaranteeing the stability of the lifting platform vehicle when operators are handling new energy batteries. The bottom of the leg unit 62 has a support chassis 613, the radial length of which is greater than the radial length of the support sleeve 61. In this embodiment, the support sleeve 61 is welded to the support base 11.

[0047] Combination Figures 1 to 7 The implementation principle of a lifting platform vehicle for replacing new energy batteries in this application embodiment is as follows: When the operator needs to use the lifting platform vehicle to transport new energy batteries, firstly, by using the forward or reverse button on the control handle 4, the electric pulley 5 is rotated to move the lifting platform vehicle to the location of the vehicle to be repaired. After reaching the designated position, the outrigger unit 62 is rotated to adjust the height of the support leg 6, so that the support chassis 613 is stably supported on the ground, ensuring the stability of the lifting platform vehicle during use. Subsequently, the operator presses the lift button at the end of the control handle 4, the drive source 21 starts, and the gear pump 222 in the drive assembly starts working, drawing hydraulic oil from the oil tank 221 and injecting it into the drive cylinder 23 through a pipeline. The output shaft of the drive cylinder 23 pushes the connecting shaft 1315, thereby driving the cross lifting arm 131 to move, so that the lifting platform 12 rises smoothly. When the lifting platform 12 reaches the required height, the lift button is released, and the lifting platform 12 stops rising. When it is necessary to lower the lifting platform 12, press the descent button, the gear pump 222 will rotate in reverse, and the hydraulic oil in the drive cylinder 23 will be drawn back to the oil tank 221, and the lifting platform 12 will descend smoothly under its own weight.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
