[0001] The utility model relates to the technical field of power batteries, in particular to a power battery frame for an electric tricycle. Background Art

[0002] Power batteries are the power source for tools, mostly referring to batteries that power electric vehicles, electric trains, electric bicycles, and golf carts.

[0003] After searching, a Chinese patent (application number "201821980375.9") discloses "a quick-change device for electric tricycle batteries". The above-mentioned device includes the battery installed in a battery frame, and the battery frame is installed at the bottom of the frame of the electric tricycle and connected to the seat box of the electric tricycle. It includes a battery box for fixing the battery, and a track for guiding the battery box to move between the inside of the seat box of the electric tricycle and the inside of the battery frame. The track is arranged at the bottom of the battery frame and extends to the inside of the seat box; a cushion is provided on the seat box, and the cushion is detachably connected to the seat box. However, during use of the above-mentioned device, when the power battery of the electric tricycle is installed, part of the battery is exposed on the outside of the mounting frame, which makes the battery easy to be damaged and has low practicality. Utility Model Content

[0004] The utility model provides a power battery frame for an electric tricycle, which solves the problem in the reference document that when the power battery of the electric tricycle is installed, part of the battery is exposed outside the installation frame, causing the battery to be easily damaged and having low practicality.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The camshaft is connected to the chassis and the chassis is connected to the chassis, and the camshaft is connected to the chassis to connect the chassis.

[0007] Preferably, the two sides and two edges of the top frame are respectively fixed on the upper outer wall of the outer fixed frame, and the top frame is fixed on the top outer wall of the inner fixed frame. An air outlet is opened on the outer wall of one side of the outer fixed frame, and a first dustproof net is embedded in the air outlet. The outer wall of one side of the inner fixed frame is opened with air inlet holes distributed at equal distances, and ventilation holes are opened on the outer wall of one side of the inner fixed frame.

[0008] Preferably, the support plate is fixed on the inner wall of the bottom of the bottom frame, and the partitions on both sides of the top of the support plate are respectively fixed on the inner walls on both sides of the inner fixed frame.

[0009] Preferably, several of the tricycle batteries are respectively abutted against the outer walls of the tops of several support plates, and several of the tricycle batteries are respectively abutted against the outer walls on the opposite sides of several partitions, and several of the first limiting plates and several of the second limiting plates are respectively abutted against the outer walls on one side of several tricycle batteries.

[0010] Through the above scheme, the tricycle battery is supported by multiple support plates, and a certain gap is created between the bottom of the tricycle battery and the bottom frame. At the same time, several partitions, several first limiting plates and several second limiting plates separate two adjacent tricycle batteries, so that there are gaps between the multiple tricycle batteries, allowing external cold air to circulate. At the same time, the outer fixing frame and the inner fixing frame cooperate with each other to protect the tricycle battery.

[0011] Preferably, the top cover is connected to the top outer wall of the top frame by bolts, and a plurality of pressure plates are respectively fixed on the bottom outer wall of the top cover.

[0013] Through the above scheme, cold air from the external environment is transported into the space between the outer fixed frame and the inner fixed frame through multiple sets of cooling fans. Then most of the cold air enters the inner fixed frame from the air inlet to dissipate heat for multiple tricycle batteries. The cold air remaining between the outer fixed frame and the inner fixed frame flows to the first dustproof net, and heat is transported to both sides of the inner fixed frame during the circulation process.

[0014] The beneficial effects of the utility model are:

[0015] Multiple support plates support the tricycle battery and allow a certain gap to exist between the bottom of the tricycle battery and the bottom frame. At the same time, several partitions, several first limiting plates and several second limiting plates separate two adjacent tricycle batteries, so that there are gaps between the multiple tricycle batteries, allowing external cold air to circulate. At the same time, the outer fixing frame and the inner fixing frame cooperate with each other to protect the tricycle battery, which can protect the tricycle battery and prevent the tricycle battery from being damaged when exposed to the external environment, thereby improving practicality.
