Description

Technical Field

[0001] The utility model relates to the technical field of battery swapping cabinets, in particular to a hydraulic trolley for a shared battery swapping cabinet. Background Technique

[0002] In the prior art, in an adjustable battery compartment grid disclosed on the Chinese patent website with the publication number CN215071750U, universal wheels for moving are installed at the bottom. After moving to a designated position through the universal wheels, a support base is installed or adjusted in height at the bottom of the cabinet body to support and fix it, or a braking device is directly installed on the universal wheels to fix them using the universal wheels. However, when using the universal wheels for moving or fixing, the following problems still exist:

[0003] 1. If each battery swapping cabinet uses universal wheels, it will invisibly increase the manufacturing cost, and it is also necessary to ensure that the installed universal wheels are on the same horizontal plane, which brings difficulties to both the manufacturing cost and the process. Moreover, the braking device on the universal wheels can only fix the wheels from rotating, but cannot fix the rotational movement on the horizontal plane of the universal wheels, and there is still a hidden danger of shaking. In addition, the universal wheels are generally made of rubber, which is easy to wear and is greatly affected by the environment, and is not conducive to the later maintenance of the battery swapping cabinet.

[0004] 2. If the support and the universal wheels are used synchronously, one of the support or the universal wheels needs to have the function of height adjustment or reduction, which will still increase the manufacturing cost. Moreover, when moving, assistance is required to hold the cabinet body to prevent it from tipping over. In addition, the diameter of the universal wheels is generally relatively small, the moving speed is limited, and there are also requirements for the moving road surface. On a bumpy road surface, it is quite difficult to move. Content of the Utility Model

[0005] Based on the existing technical problems, the utility model provides a hydraulic trolley for a shared battery swapping cabinet.

[0006] The hydraulic trolley for a shared battery swapping cabinet provided by the utility model includes a rectangular bracket. The front end of the rectangular bracket is provided with a front wheel with adjustable height, and the rear end of the rectangular bracket is provided with a rear wheel.

[0007] A linear driving source is installed in the width direction at the front end of the rectangular bracket. A lifting bracket is arranged at the top of the rectangular bracket. The rectangular bracket realizes the movable support action with the lifting bracket through a cross scissor bracket.

[0008] The extending end of the linear driving source is hinged with a support rod. The two ends of the support rod are respectively fixedly connected with the upper partial rod segments at the front ends of the two cross scissor brackets, so as to realize the action that the linear driving source drives the lifting bracket to lift upward through the cross scissor brackets.

[0009] Preferably, a sleeve which is the same as the mounting handle or rope is fixedly mounted at the middle of the front end of the rectangular bracket.

[0010] With the above technical solution, the trolley can be pulled or pushed by passing the rope or the handle through the sleeve.

[0011] Preferably, the rectangular bracket is welded from channel steels with three notches all facing inwards, and both ends of the transmission shaft of the rear wheel are installed with the tail of the rectangular bracket through bearings or bearing seats.

[0012] Through the above technical solution, the width of the rectangular bracket can be determined according to the actual width of the battery exchange cabinet, and the rear wheels are installed at the tail of the rectangular bracket, which makes it easier to push the cart.

[0013] Preferably, the linear drive source is composed of a hydraulic cylinder, and a cylinder body of the hydraulic cylinder is hinged to the front end of the rectangular bracket.

[0014] Through the above technical solution, the hydraulic cylinder has a very strong driving force. If the battery swap cabinet is very light, a linear motor or a motor and a screw linear motion mechanism can also be used to achieve linear drive action.

[0015] Preferably, the lifting bracket is composed of channel steels with both sides facing inward and the rear facing downward, and the middle parts of the opposite inner walls of the channel steels on both sides are fixedly connected by connecting rods, and the channel steel at the rear is provided with a clearance groove that is movably sleeved on the surface of the rear wheel.

[0016] Through the above technical solution, the connecting rod can fasten the channel steels on both sides together to form an integrated structure with stronger bearing capacity.

[0017] Preferably, the upper and lower ends of the tail of the cross scissors bracket are respectively hinged to the tail of the rectangular bracket and the lifting bracket through pins, and the upper and lower ends of the front part of the cross scissors bracket are equipped with rolling bearings that are rollingly connected to the inner wall of the channel steel.

[0018] Through the above technical solution, the existing grooves of the channel steel are utilized. On the one hand, it is convenient for the rolling bearing to roll on its inner wall. On the other hand, the grooves can have good mechanical properties and can bear a power exchange cabinet with a large gravity. At the same time, the connecting rod is set in the middle to prevent the connecting rod from obstructing the rolling trajectory of the rolling bearing.

[0019] The beneficial effects of the present invention are:

[0020] By setting the action of the linear drive source to drive the lifting bracket to lift upward through the cross scissor bracket, on the one hand, the universal wheels at the bottom of the original battery swapping cabinet can be removed, and support feet with a fixed height can be directly adopted, reducing production costs. On the other hand, the larger the diameters of the front and rear wheels, the wider the applicable road surface, and there is no need to worry about the difficulty of moving the battery swapping cabinet due to uneven road surfaces. At the same time, the adjustable height is much higher than the adjustable height of the existing universal wheels, and the production cost is low, small and flexible, making it convenient to use.

[0030] In order to lift the power exchange cabinet smoothly, a linear drive source is installed in the front width direction of the rectangular bracket 1, and a lifting bracket 4 is provided on the top of the rectangular bracket 1. The rectangular bracket 1 realizes an active supporting action with the lifting bracket 4 through a cross scissors bracket 5.

[0031] The extended end of the linear drive source is hinged with a support rod 6, and the two ends of the support rod 6 are respectively fixedly connected to the upper rod sections of the front ends of the two cross scissors brackets 5, so that the linear drive source drives the lifting bracket 4 to lift upward through the cross scissors bracket 5.

[0032] The lifting is specifically achieved as follows: the linear drive source is composed of a hydraulic cylinder 8, and the cylinder body of the hydraulic cylinder 8 is hinged to the front end of the rectangular bracket 1. The hydraulic cylinder has a strong driving force. If the battery exchange cabinet is very light, a linear motor or a motor and a screw linear motion mechanism can also be used to achieve the linear drive action.

[0033] In order to make the entire trolley stable and low in manufacturing cost, the lifting bracket 4 is composed of channel steels with both sides facing inward and the rear facing downward, and the middle parts of the inner walls of the channel steels on both sides are fixedly connected by connecting rods 9, and the channel steel at the rear is provided with a clearance groove 10 that is movably sleeved on the surface of the rear wheel 3.
