[0001] The utility model relates to the technical field of battery casings, and particularly relates to a shock-absorbing plastic casing for an electric bicycle battery. Background Art

[0002] An electric bicycle is a vehicle that uses a storage battery as an auxiliary energy source and is equipped with an electronic control device on the basis of an ordinary bicycle.

[0003] The battery plays a power supply role in the electric bicycle, and most of the current batteries are detachably arranged on the electric bicycle, which is convenient for charging the battery. After the battery is installed on the electric bicycle, the electric bicycle can be powered by inserting the plug on the electric bicycle into the socket on the battery.

[0004] However, the electric bicycle is prone to jolting during driving. The plug on the electric bicycle and the socket on the battery only insert the plug into the socket without other fixing methods, resulting in the separation of the plug and the socket, thereby reducing the stability of battery use. For this reason, we propose a shock-absorbing plastic casing for an electric bicycle battery. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides an electric bicycle battery shock-absorbing plastic housing as shown in Figures 1-4 which includes a housing. A socket base 103 is inserted through the outer wall of the housing. The housing includes a first plastic shell 101 and a second plastic shell 102. The socket base 103 is fixedly inserted through the outer wall of the first plastic shell 101. After the first plastic shell 101 and the second plastic shell 102 are fixed together, a handle is formed at the top of the first plastic shell 101 and the second plastic shell 102, which is convenient for moving the housing and improves the convenience of using the housing.

[0023] In a preferred embodiment, a locking mechanism is provided on the outer wall of the socket base 103. The locking mechanism is used to position the plug inserted into the socket base 103. The locking mechanism includes symmetrically arranged U-shaped rods 201. The ends of the U-shaped rods 201 are fixedly connected with rotating shafts 202. A plurality of rotating holes 203 are formed in the outer wall of the socket base 103. The outer wall of the rotating shaft 202 is rotatably connected with the inner wall of the rotating hole 203. An elastic mechanism is arranged between the rotating shaft 202 and the socket base 103. After the plug of the electric bicycle is inserted into the socket base 103, the two U-shaped rods 201 are rotated, so that the two U-shaped rods 201 both abut against the outer wall of the plug. Since the plug becomes thinner towards the wire position, the two U-shaped rods 201 can hook the plug inserted into the socket base 103, preventing the plug from separating from the socket base 103 due to the bumpy vibration of the electric bicycle, thereby improving the stability of the battery operation.

[0024] Among them, the elastic mechanism includes an annular groove 301 formed in the inner wall of the rotating hole 203. A torsion spring 302 is arranged on the inner wall of the annular groove 301. The torsion spring 302 is sleeved on the outer wall of the rotating shaft 202. One end of the torsion spring 302 is fixedly connected with the outer wall of the annular groove 301, and the other end of the torsion spring 302 is fixedly connected with the inner wall of the torsion spring 302. Through the elastic action of the torsion spring 302, the rotating shaft 202 inserted in the torsion spring 302 always has a tendency to rotate automatically. This is manifested on the two U-shaped rods 201 as the two U-shaped rods 201 always have a tendency to rotate relative to each other. That is, during operation, first rotate the two U-shaped rods 201 relative to each other by hand to spread the two U-shaped rods 201 apart, so that the plug can be stably inserted into the socket base 103. After the plug is inserted into the socket base 103, release the U-shaped rods 201, and under the elastic action of the torsion spring 302, the two U-shaped rods 201 will automatically rebound to abut against the plug, thereby improving the stability of the locking mechanism.

[0025] Among them, a plurality of jacks 401 are provided on one side of the first plastic shell 101. The inner walls of the plurality of jacks 401 are all movably inserted and connected with mounting bolts 402. The plurality of mounting bolts 402 are respectively threadedly connected with one side of the second plastic shell 102. The battery is clamped in the first plastic shell 101, then the second plastic shell 102 and the first plastic shell 101 are aligned, the second plastic shell 102 and the first plastic shell 101 are assembled into a shell, and finally the mounting bolts 402 are inserted into the jacks 401 and screwed into the second plastic shell 102, and the assembly and fixation of the shell can be completed, so that the electric bicycle battery can be stably used.

[0026] Furthermore, rubber pads 501 are provided at the bottom ends of the first plastic shell 101 and the second plastic shell 102. An adhesive layer 502 is provided between the rubber pads 501 and the first plastic shell 101 and the second plastic shell 102. Through the arrangement of the rubber pads 501, when the battery is in use, the shell is inserted into the installation cavity of the electric bicycle, and the rubber pads 501 will abut against the inner wall bottom end of the installation cavity. Thus, when the electric bicycle is running, the rubber pads 501 can buffer the vibration generated by bumps, effectively reduce vibration, thereby prolonging the service life of the shell, ensuring the stable use of the battery, and fixing the rubber pads 501 to the first plastic shell 101 and the second plastic shell 102 through the adhesive layer 502, ensuring the stability of the rubber pads 501 in use, and at the same time facilitating the replacement of the severely worn rubber pads 501, thereby improving the convenience of use of the rubber pads 501.

[0027] Even further, positioning blocks 504 are fixedly connected to the bottom ends of the first plastic shell 101 and the second plastic shell 102 respectively. A plurality of positioning holes 503 are provided at the top end of the rubber pad 501. The outer walls of the plurality of positioning blocks 504 are respectively inserted and connected with the inner walls of the plurality of positioning holes 503. Through the mutual limitation of the positioning blocks 504 and the positioning holes 503, after the rubber pad 501 is attached to the bottom ends of the first plastic shell 101 and the second plastic shell 102 through the adhesive layer 502, the rubber pad 501 is not prone to lateral displacement, thereby improving the stability of the rubber pad 501 in use.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
