DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1: This embodiment is intended to solve the problem that the casing of some plastic batteries is too complicated to install, which may make it difficult to remove the casing when the battery needs to be repaired or replaced, resulting in a longer time for repairing or replacing the battery, which reduces the work efficiency. Please refer to Figure 1 - Figure 5A detachable plastic battery casing comprises a protective casing 100 and a battery body 200.

[0026] The battery body 200 is installed inside the protective shell 100. The protective shell 100 includes a top shell 110 and a bottom shell 120. The top shell 110 is installed on the top of the bottom shell 120. A placement space 130 is provided inside the bottom shell 120. The battery body 200 is located in the placement space 130.

A slide groove 340 is provided inside the bottom shell 120. The slide rail 310 is installed in the slide groove 340. The limit plate 330 is installed on both sides of the slide rail 310. A groove 350 is provided on the side wall of the top shell 110. The pulley 320 is installed in the groove 350. The pulley 320 and the slide rail 310 are slidably matched. This makes it more convenient to install and remove the battery. Through the cooperation of the pulley 320 and the slide rail 310, the top shell 110 can be easily slid to separate or connect it with the bottom shell 120. When it is necessary to repair or replace the battery, the housing can be quickly disassembled to enter the placement space 130. This reduces the time for disassembly and reassembly and improves the efficiency of repair and replacement.

[0027] Stoppers 131 are installed at both ends of the chute 340 to block the pulley 320. The stoppers 131 are arranged as rectangular blocks. The setting of the stoppers 131 can effectively prevent the pulley 320 from exceeding a predetermined range, and avoid the pulley 320 from escaping from the chute 340 or abnormal movement.

[0028] A plug rod 121 is installed on the bottom shell 120, and a slot 111 is provided on the top shell 110, and the plug rod 121 is plugged into the slot 111. The design of the plug rod 121 and the slot 111 can further ensure the stable connection of the battery and reduce the possibility of the battery loosening and falling off during use. A damping ring 112 is installed in the slot 111, and the outer diameter of the damping ring 112 corresponds to the diameter of the slot 111, and the inner diameter of the damping ring 112 corresponds to the diameter of the plug rod 121. The damping ring 112 can reduce the impact of the plug rod 121 and the slot 111 during plugging, thereby protecting the plug-in components from damage and increasing the stability and reliability of the plug-in. The outer diameter and inner diameter of the damping ring 112 can accurately correspond to the diameters of the slot 111 and the plug rod 121, thereby achieving better plug-in fit and avoiding plug-in failure caused by loose or overtightening.

[0029] In this embodiment: a connecting assembly 300 is provided between the top shell 110 and the bottom shell 120, the slide rail 310 is installed in the slide groove 340, the limit plate 330 is installed on both sides of the slide rail 310, the side wall of the top shell 110 is provided with a groove 350, the pulley 320 is installed in the groove 350, and the pulley 320 and the slide rail 310 are slidably matched, so that the installation and removal of the battery becomes more convenient, through the cooperation of the pulley 320 and the slide rail 310, the top shell 110 can be easily slid to separate or connect it with the bottom shell 120, so that when the battery needs to be repaired or replaced, the outer shell can be quickly removed to enter the placement space 130, thereby reducing the time for disassembly and reassembly and improving the efficiency of repair and replacement.

[0030] Embodiment 2: This embodiment is intended to solve the problem of lack of fixing device between the battery and the housing. In the absence of such fixing device, the positive and negative electrodes inside the battery may collide with each other, which may cause the battery to produce ghost fire during movement. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Figure 5 .

[0031] In order to avoid collision between the positive and negative electrodes inside the battery, the stopper 321 is installed in the placement space 130 and contacts the battery body 200. The stopper 321 adopts a rubber hemispherical convex block design, so that the battery body 200 can maintain its position securely during movement. At the same time, in order to ensure the stability of the position of the battery body 200, a corresponding mounting groove 132 is also opened in the placement space 130, and the battery body 200 is engaged with the mounting groove 132 to prevent it from moving or shaking.

[0032] A plurality of ventilation holes 113 are provided on the outer wall of the top shell 110, and the ventilation holes 113 are connected to the placement space 130. When the battery is working, heat is generated. If there is not enough ventilation and heat dissipation, the battery temperature is too high, which may affect the battery life and safety. By providing the ventilation holes 113 on the outer wall of the top shell 110, the air in the placement space 130 can be directly in contact with the outside air, which promotes air circulation and heat dissipation, effectively prevents overheating and overloading, and thus protects the normal operation of the battery.

[0033] The protective shell 100 is configured as a polypropylene shell as a whole, and an anti-corrosion coating 140 is provided on the outer side of the protective shell 100, and the anti-corrosion coating 140 is configured as an epoxy paint layer. Polypropylene material is a commonly used engineering plastic, which has high wear resistance, chemical corrosion resistance and weather resistance. The protective shell 100 is configured as a polypropylene shell as a whole, which can provide good physical protection for the battery and resist external factors such as impact, friction and chemical corrosion in daily use.

[0034] At the same time, the provision of the anti-corrosion coating 140 further increases the protective performance of the housing. The epoxy paint layer is a common anti-corrosion coating, which has high corrosion resistance and weather resistance. Applying the anti-corrosion coating 140 to the outer side of the protective housing 100 can effectively prevent the housing from contacting with moisture, corrosive gases, chemicals, etc. in the environment, and provide additional anti-corrosion and anti-oxidation protection.

[0035] In the present embodiment: a stopper 321 is installed in the placement space 130, and the stopper 321 is set as a rubber hemispherical protrusion. The stopper 321 contacts the battery body 200, so that the battery body 200 has a clear fixed position in the placement space 130 to prevent it from moving or shaking during movement or vibration. A mounting groove 132 corresponding to the battery body 200 is opened in the placement space 130, and the battery body 200 is engaged with the mounting groove 132 to prevent the positive and negative poles inside the battery from colliding, thereby reducing the risk of ghost fires in the battery and improving the safety and stability of the battery.

[0036] Setting the entire protective shell as a polypropylene shell can provide good physical protection for the battery and resist external factors such as impact, friction and chemical corrosion in daily use.

[0037] At the same time, the setting of anti-corrosion coating further increases the protective performance of the shell. Epoxy paint layer is a common anti-corrosion coating, which has high corrosion resistance and weather resistance. Applying anti-corrosion coating to the outside of the protective shell can effectively prevent the shell from contacting with moisture, corrosive gases, chemicals, etc. in the environment, and provide additional anti-corrosion and anti-oxidation protection.

[0038] In the present embodiment: a stop block is installed in the placement space, and the stop block is set as a rubber hemispherical protrusion. The stop block contacts the battery body, so that the battery body has a clear fixed position in the placement space to prevent it from moving or shaking during movement or vibration. A mounting groove corresponding to the battery body is opened in the placement space, and the battery body is engaged with the mounting groove to prevent the positive and negative poles inside the battery from colliding, thereby reducing the risk of ghost fires in the battery and improving the safety and stability of the battery.
