DETAILED DESCRIPTION

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0028] like Figures 1 to 8 As shown, the highly compatible quick-release automobile plastic battery compartment described in this embodiment includes a fixed compartment and a movable compartment;

[0029] The fixed cabin includes a first warehouse body 101, an air pump 102, an electromagnetic valve 103 and two particle capsules 104. The front end and the bottom of the first warehouse body 101 are both open structures. The left and right inner walls of the first warehouse body 101 are respectively provided with a Z-shaped first guide rail 105. The two particle capsules 104 are symmetrically arranged on the rear end wall of the first warehouse body 101. The particle capsules 104 contain micro particles with good fluidity. The front end of the particle capsule 104 has a blind hole when the particle capsule 104 is in a natural state. The air pump 102 is installed on the rear end wall of the first warehouse body 101 and is located between the two particle capsules 104. The electromagnetic valve 103 is fixedly connected to the air pump 102. The rear ends of the two particle capsules 104 are respectively connected to the electromagnetic valve 103 through an air pipe 106; specifically, the first warehouse body 101 and the first guide rail 105 are made of high temperature and corrosion resistant plastic material, and the particle capsules 104 are made of flexible material;

[0030] The movable cabin includes a second warehouse body 201. Specifically, the second warehouse body 201 is made of high temperature resistant and corrosion resistant plastic material. The second warehouse body 201 has a chamber for accommodating a power battery 208. The rear ends of the left and right side outer walls of the second warehouse body 201 are axially connected to two first rollers 202 arranged at a front-to-back interval. The rear end of the second warehouse body 201 is symmetrically provided with two locking bosses 203 for cooperating with corresponding blind holes. During assembly, the second warehouse body 201 slides into the first warehouse body 101 under the guidance of the first guide rail 105 through the first roller 202, so that the locking boss 203 is correspondingly inserted into the blind hole and is covered and locked by the corresponding particle capsule 104.

[0031] During actual use, the power battery 208 is installed in the compartment of the second compartment body 201, and then the first rollers 202 on the left and right side walls of the second compartment body 201 are made to correspond one by one to the first guide rails 105 on the left and right inner side walls of the first compartment body 101, so that the first rollers 202 all slide into the first guide rails 105, and then the second compartment body 201 is continued to be pushed. Under the guiding support of the first guide rails 105, since the two first rollers 202 on the same side are arranged at intervals front and back, the second compartment body 201 can drive the power battery 208 to swing downward to avoid the external car skirt part, until the locking boss 203 on the second compartment body 201 is correspondingly inserted into the blind hole on the particle capsule 104, and the second compartment body 201 is supported horizontally in the first bin body 101 under the cooperation of the first roller 202 and the first guide rail 105, and the height of the power battery 208 is raised at the same time. Then the solenoid valve 103 connects the air pipe 106 with the air pump 102, and the air pump 102 evacuates the particle capsule 104 through the air pipe 106, so that the particles in the particle capsule 104 are transformed from a flowing state to a solid state under the action of the "vacuum accumulation effect", and the locking boss 203 is adaptively wrapped and locked. The solenoid valve 103 disconnects and connects the air pipe 106 with the air pump 102, so that the particle capsule 104 maintains a vacuum state, and the movable cabin and the fixed cabin are fixedly connected as a whole, thereby completing the installation of the power battery 208;

[0032] When the power battery 208 needs to be disassembled, the solenoid valve 103 connects the air pipe 106 with the air pump 102, and the air pump 102 pumps the outside air into the particle capsule 104 through the air pipe 106, so that the particles in the particle capsule 104 resume the flow state, thereby unlocking the locking boss 203, and then the power battery 208 is gradually pulled out through the second bin body 201. At this time, with the cooperation of the first roller 202 and the first guide rail 105, the second bin body 201 drives the power battery 208 to swing downward to avoid the skirt part of the car, thereby lowering the height of the power battery 208. With the cooperation of the two first rollers 202 and the first guide rail 105, the power battery 208 is completely pulled out to complete the disassembly of the power battery 208.

[0033] This embodiment arranges a Z-shaped first guide rail 105 on the left and right sides of the fixed cabin and two first rollers 202 spaced apart in the front and rear on the left and right sides of the movable cabin respectively, so that the obstruction of the skirt of the car to the disassembly and assembly can be avoided during the disassembly and assembly of the power battery 208, and there is no need to lift the car as a whole, thereby improving the disassembly and assembly efficiency of the power battery 208 and making the disassembly and assembly more convenient; at the same time, the locking boss 203 is adaptively wrapped and locked by the particle capsule 104, so that there is no restriction on the structure and size of the locking boss 203, which can greatly expand the compatibility of the battery compartment.

[0034] Based on the above embodiment, further, the rear end wall of the first warehouse body 101 is provided with a socket 107, and the socket 107 is electrically connected to the external automobile power system, and the rear end wall of the second warehouse body 201 is also provided with a plug 204 for plugging and matching with the socket 107, and the plug 204 is electrically connected to the power battery 208. Specifically, after the second warehouse body 201 drives the power battery 208 to completely slide into the first warehouse body 101, the plug 204 on the second warehouse body 201 is correspondingly inserted into the socket 107 on the first warehouse body 101, so as to realize the electrical connection between the power battery 208 and the external automobile power system, and the assembly is more convenient.

[0035] Based on the above embodiment, further, the fixed cabin also includes an air duct 108 and a plurality of cooling nozzles 109. The air duct 108 is fixedly installed on the rear end arm wall of the first warehouse body 101. One end of the air duct 108 is connected to the solenoid valve 103. The plurality of cooling nozzles 109 are spaced and arranged side by side on the inner top wall of the first warehouse body 101. The plurality of cooling nozzles 109 are all connected to the other end of the air duct 108. The nozzle of the cooling nozzle 109 is arranged obliquely downward toward the front end opening position of the first warehouse body 101.

[0036] Specifically, after the power battery 208 is installed and the vehicle is running, the solenoid valve 103 connects the air duct 108 with the air pump 102, and the air pump 102 pumps outside air into the air duct 108. The outside air is dispersed into each cooling nozzle 109 through the air duct 108, and then sprayed from the nozzle of each cooling nozzle 109 toward the top of the power battery 208, so as to cool down the power battery 208, with higher cooling effect and lower noise.

[0037] Based on the above embodiment, further, a pressure sensor 110 is fixedly installed on the inner wall of the rear end of the first chamber 101. In actual use, the pressure sensor 110 is squeezed by the movable chamber and generates an induction signal, so as to detect whether the power battery 208 is installed in place, and at the same time, it is convenient to control the timing of the air pump 102 to vacuum the particle capsule 104.

[0038] Based on the above embodiment, further, a handle 205 is fixedly installed at the front end of the second compartment body 201. In this embodiment, the handle 205 is provided to facilitate pushing and pulling the movable compartment during the disassembly and assembly process, and the operation is more convenient.

[0039] Based on the above embodiment, a filter 111 is further connected between the rear end of the particle capsule 104 and the trachea 106. By setting the filter 111, the particles in the particle capsule 104 are prevented from entering the trachea 106, ensuring the smooth passage in the trachea 106 and the normal operation of the solenoid valve 103.

[0040] Based on the above embodiment, the locking boss 203 is further in a T-shaped structure. In this way, the locking boss 203 is formed with an undercut, and after the particle capsule 104 covers and locks the locking boss 203, the connection between the particle capsule 104 and the locking boss 203 is more secure and not easy to loosen, so that the movable cabin will not be pulled out when in use.

[0041] Based on the above embodiment, further, a guide block 112 is fixed to the front end of the first guide rail 105. In this embodiment, the guide block 112 is provided to roughly guide the first roller 202 so that the first roller 202 can smoothly enter the first guide rail 105.

[0042] Based on the above embodiment, further, the front ends of the left and right side walls of the first warehouse body 101 are hinged with second guide rails 113, the front ends of the left and right side walls of the first warehouse body 101 are provided with arc-shaped strip holes 114, the rear end of the second guide rail 113 is convexly provided with a detent pin 115, the detent pin 115 is limitedly engaged in the strip hole 114, the rear end of the second guide rail 113 is provided with an arc segment, and the arc segment of the second guide rail 113 is provided with a tapered guide surface facing the inner side of the first warehouse body 101;

[0043] The front ends of the left and right side walls of the second bin body 201 are fixed with a shifting block 206 for shifting the shifting pin 115, and the rear ends of the left and right sides of the second bin body 201 are axially connected with a second roller 207, the height of the second roller 207 is lower than that of the first roller 202, and the outer side of the second roller 207 is a conical surface.

[0044] Specifically, before the movable cabin is loaded into the fixed cabin, the second guide rail 113 is in a drooping state under the action of its own gravity, and the arc segment of the second guide rail 113 is tangent to the ground. When installing the power battery 208, the second warehouse body 201 is placed on the ground, and the second rollers 207 on both sides are aligned with the second guide rail 113 respectively, and then the handle 205 is held to push the second warehouse body 201 toward the first warehouse body 101, so that the conical surface of the second roller 207 contacts the conical guide surface of the second guide rail 113. During the contact process of the two conical surfaces, the second warehouse body 201 is corrected in the horizontal direction, and the second roller 207 moves along the second The arc section of the guide rail 113 climbs until the first roller 202 on the second warehouse body 201 passes through the guide block 112 and is clamped into the first guide rail 105. Then, the second roller 207 passes over the second guide rail 113 and slides into the first warehouse body 101 with the second warehouse body 201. The front and rear first rollers 202 are both clamped into the first guide rail 105 until the second warehouse body 201 completely slides into the first warehouse body 101. At this time, the shifting block 206 pushes the shifting pin 115 to slide along the strip hole 114, so that the second guide rail 113 swings upward and retracts, thereby further reducing the disassembly and assembly strength of the power battery 208, making the loading of the movable cabin more convenient.

[0045] The above is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
