Description

Technical Field

[0001] The utility model relates to the technical field of new energy vehicle batteries, and in particular to an anti-touch protection cover for high-voltage copper bars in a battery pack. Background Art

[0002] As the main energy source for electric bikes in new energy vehicles, the battery pack generally integrates many battery cell groups. After the batteries are grouped, the voltage of the entire battery pack can reach several hundred volts, while the human body can tolerate a safe voltage of 36V. Therefore, the voltage in the battery pack of new energy vehicles far exceeds the human body's safe voltage. According to GB3805, when the voltage of electrical equipment exceeds 24V, safety protection measures must be taken to prevent direct contact with the elevator. The copper busbar is the bridge connecting the cells in the battery pack of new energy vehicles. After connecting the cells, it takes on the accumulated voltage of the entire group of cells. Whether in the actual assembly of the battery pack copper busbar or after the battery pack is assembled, the copper busbar in the exposed non-insulated part may cause foreign objects or the human body to contact the charged body, thereby causing hidden dangers of safety accidents.

[0069] A guide groove 303 is provided on the side where the upper buckle body 30101 cooperates with the upper protective cover body 20101, and a guide groove 303 is provided on the side where the lower buckle body 30201 cooperates with the lower protective cover body 20201. A fixing groove 304 is provided in the guide groove 303.

[0070] The guide rail 203 of the upper protective cover 201 is placed in the guide groove 303 of the upper buckle body 30101, and the guide rail 203 of the lower protective cover 202 is placed in the guide groove 303 of the lower buckle body 30201;

[0071] When the upper protective cover 201 and the lower protective cover 202 are in the buckled state, the fixing protrusion 204 of the upper protective cover 201 is embedded in the fixing groove 304 of the upper buckle body 30101 , and the fixing protrusion 204 of the lower protective cover 202 is embedded in the fixing groove 304 of the lower buckle body 30201 .

[0072] In this embodiment, a plurality of limit platforms 306 are arranged at intervals on the inner side surface of the upper buckle body 30101 and the inner side surface of the lower buckle body 30201.

[0073] This embodiment further defines the structure of the upper buckle 301 and the lower buckle 302, and the ends of the two are bent to form an upper protective cover connecting portion 30102 and a lower protective cover connecting portion 30202 respectively; and the interior of the bent structure of the upper protective cover connecting portion 30102 is an upper protective cover connecting groove, and the upper protective cover mounting portion 20102 of the upper protective cover 201 can be embedded and slidably connected in the upper protective cover connecting groove. Similarly, the lower protective cover mounting portion 20202 of the lower protective cover 202 can be embedded and slidably connected in the lower protective cover connecting groove.

[0074] The specific structure of the sliding connection is: the surface of the upper protective cover connection part 30102 and the lower protective cover connection part 30202 are both corrugated structures 205;

[0075] The upper cover mounting portion 30102 has a corrugated groove 305 formed inside thereof to match the corrugated structure 205 of the upper cover connecting portion 20102 , and the lower cover mounting portion 30202 has a corrugated groove 305 formed inside thereof to match the corrugated structure 205 of the lower cover connecting portion 20202 .

[0076] In order to achieve the connection between the upper buckle 301 and the lower buckle 302, an upper buckle protrusion 30103 is protrudingly formed at the end of the upper protective cover mounting portion 30102 of this embodiment;

[0077] A lower buckle recess 30203 is provided at the end of the lower protective cover mounting portion 30202;

[0078] The upper buckle 301 and the lower buckle 302 are positioned and fixed by the upper buckle protrusion 30103 and the lower buckle recess 30203 .

[0079] When the upper buckle 301 and the lower buckle 302 of this embodiment are combined, the limiting platform 306 presses and embeds into the insulating rubber layer 101 of the copper busbar 1 .

[0080] In order to facilitate opening of the upper and lower protective covers, the upper protective cover and the lower protective cover of this embodiment are both provided with protective cover opening and closing handles.

[0081] When the copper busbar 1 has not yet been connected to the high-voltage power supply of the battery pack, the protective cover 2 covers the exposed part of the copper busbar 1. The copper busbar 1 is in an absolutely protected state. Regardless of any mishandling of parts or parts falling, the copper busbar 1 will not touch the charged body as a conductor, thereby causing an accident. When the copper busbar 1 is being connected to the high-voltage power supply of the battery pack, the protective cover 2 is opened, and the copper busbar mounting hole 102 is exposed and used to connect to the load. After the copper busbar 1 connection process is completed, the upper protective cover 201 is closed and the lower protective cover 202 is opened. At this time, the copper busbar 1 is protected against touch throughout the entire process during the battery pack installation.

[0082] In the above technical solution, the utility model provides a high-voltage copper busbar anti-touch protection cover in a battery pack, which has the following beneficial effects:

[0083] The protective cover 2 of the utility model is arranged on the copper busbar 1 part, has good versatility, has obvious advantages in cost, and has wide applicability. The protective cover 2 uses a buckle structure to connect the upper protective cover 201 and the lower protective cover 202, which can be easily opened and closed, and the relative positions of the upper and lower protective covers can be adjusted in a sliding manner, which is convenient for use.

[0084] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
