Description

Technical Field

[0001] The utility model relates to the technical field of battery replacement with a battery replacement box, and specifically to a battery replacement structure for a battery replacement forklift. Background Art

[0002] An electric forklift is a forklift that uses electricity to operate. Most of them work on batteries. A battery is a type of battery that can store limited electrical energy and use it in a suitable place. Its working principle is to convert chemical energy into electrical energy.

[0003] At present, in order to ensure that electric forklifts can be used continuously, electric forklift batteries are usually replaced. For the convenience of installation, the battery replacement battery box is usually installed inside the electric forklift frame in a sliding manner. When installing the existing battery replacement battery box, guide wheels are usually installed on both sides of the electric forklift frame, and the two ends of the battery replacement battery box are placed on the guide wheels and in contact with the guide wheels to achieve the sliding installation of the battery replacement box. However, since the battery replacement battery box itself has a certain weight, the bottom of the battery replacement battery box is locally subjected to a large gravity, which can easily cause cracks and damage at both ends of the battery box. Based on this, a battery replacement structure for a battery replacement forklift that solves the above problems is proposed. Utility Model Content

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the battery-swapping structure for a battery-swapping forklift in this embodiment includes a battery-swapping frame 1, two battery-swapping cavities 2 are arranged in front of the battery-swapping frame 1, the battery-swapping cavity 2 is used to install and place the battery-swapping battery box, and a connecting plug 3 is installed inside the battery-swapping frame 1 behind the battery-swapping cavity 2. The connecting plug 3 is used to connect to the connecting socket on the surface of the battery-swapping box to connect the battery inside the battery-swapping box and the equipment circuit of the electric forklift, and support plates 4 are installed on both sides of the battery-swapping frame 1 below the battery-swapping cavity 2. The support plates 4 are used to provide support for the installation of the guide roller assembly, and a plurality of guide roller assemblies are detachably installed above the support plates 4 from front to back. The guide roller assemblies are used to The installation of the battery box plays a guiding role. At the same time, the guide roller assembly can support the bottom of the battery box, effectively preventing the surface of the battery box from being damaged by large gravity. Protective pads 6 are installed at both ends of the battery exchange cavity 2. The protective pads 6 are used to protect and limit the two ends of the battery exchange battery box to avoid hard contact between the two ends of the battery exchange battery box and the battery exchange frame 1. A locking device 7 is installed inside the battery exchange frame 1 in front of the two battery exchange cavities 2. A locking plate 8 is rotatably installed on the locking device 7.

[0021] Specifically, the guide roller assembly includes a connecting shaft 501, a bearing member 502 and a guide roller body 503. Bearing members 502 are installed at both ends of the guide roller body 503. The bearing member 502 is rotatably connected to the connecting shaft 501. The two connecting shafts 501 are detachably installed on the support plate 4. The guide roller body 503 realizes the rotation function through the bearing member 502. The guide roller body 503 is installed through the connecting shaft 501. When the battery swap box is installed, the guide roller body 503 is driven to rotate, which is convenient for supporting and moving the battery swap box.

[0022] Furthermore, the support plate 4 is U-shaped, and a plurality of placement grooves 9 are arranged on the upper ends of both sides of the support plate 4 from the front and rear ends. The placement grooves 9 are U-shaped, and planes 10 are arranged on the front and rear parts of the surface of the connecting shaft 501. The connecting shaft 501 is located inside the placement groove 9. The connecting shaft 501 is installed inside the placement groove 9 by snapping. The plane 10 on the surface of the connecting shaft 501 contacts the inside of the placement groove 9 to prevent the connecting shaft 501 from rotating together with the guide roller body 503 and to prevent the connecting shaft 501 from being displaced inside the placement groove 9.

[0023] Furthermore, limit blocks are installed at the rear ends of the battery exchange cavity 2 on both sides of the connecting plug 3, and rubber blocks 11 are installed at the front ends of the limit blocks. The limit blocks are used to limit the battery exchange battery box so that the battery exchange battery box socket and the connecting plug 3 are connected. The rubber block 11 has a certain elasticity and is used to protect the battery exchange battery box.

[0024] Furthermore, guide surfaces 12 are provided in front of the opposite end surfaces of the protective pad 6. The provision of the guide surfaces 12 facilitates the installation of the battery exchange box at a suitable position and is conducive to the alignment and connection of the socket on the surface of the battery exchange box and the connecting plug 3.

[0025] Furthermore, the surface of the guide roller body 503 extends above the support plate 4, and the guide roller body 503 contacts the lower end surface of the battery swapping battery box to support the surface of the battery swapping battery box.

[0026] The method of using this embodiment is as follows: when using the battery swap structure for the battery swap forklift, the battery swap battery drives the battery swap battery box to move through an external moving device, and the battery swap battery box is placed inside the battery swap cavity 2. At the same time, the lower end of the battery swap battery box is in contact with the surface of the guide roller body 503. As the battery swap battery box is pushed into the battery swap cavity 2, the battery swap battery box drives the guide roller body 503 to rotate, which facilitates the placement of the battery swap battery box into the battery swap cavity 2. At the same time, the guide roller body 503 supports the bottom end of the battery swap battery box, and the socket on the surface of the battery swap battery box is connected to the connecting plug 3 to realize the power supply of the battery swap battery box and the internal circuit of the electric forklift, and the locking plate 8 on the locking device 7 is used to limit the battery swap battery box to realize the installation of the battery swap battery box.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents.
