Existing battery protection covers have disadvantages such as poor heat dissipation and poor structural stability.

[0003] The patent with application number CN202221907442.0 involves the technical field of new energy vehicle batteries, and discloses a shockproof protective shell for new energy vehicle batteries, including a protective shell body, air outlets are fixedly arranged in the middle of both side walls of the protective shell body, a base is fixedly arranged at the bottom of the protective shell body, first springs are fixedly arranged on both sides of the top of the base, first resistors are fixedly sleeved inside the two first springs, a support base is fixedly connected to the top of the two first resistors, and second fixed plates are fixedly arranged on the outer walls of both sides of the support base. In the utility model, a first resistor, a first spring, a support base, and a rubber pad are provided. When the car encounters bumpy road conditions, the car battery will squeeze the first spring downward, and the first spring will rebound under pressure.

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the utility model, rather than all embodiments.

[0019] In the description of the present utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present utility model. When a mechanism is referred to as being "fixed to" another mechanism, it may be directly on the other mechanism or there may also be a centered mechanism. When a mechanism is considered to be "connected to" another mechanism, it may be directly connected to the other mechanism or there may be a centered mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it may be directly set on the other mechanism or there may be a centered mechanism at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0020] like Figures 1 to 4 As shown, the utility model is a new energy vehicle high-voltage electrical appliance protective cover, comprising: a shell 1 that protects the battery; heat dissipation facilities 2 opened on both sides of the shell 1, through which external air can enter the interior of the shell 1 to evenly dissipate heat on the battery surface; a battery cover 3 fixedly installed on the inner wall of the shell 1, which fixes and protects the battery from both upper and lower directions.

[0021] A battery mounting port 31 for mounting the battery, a water cooling plate mounting groove 32 for mounting the water cooling plate, and a snap-in groove 33 are provided on one side of the battery cover 3 close to the battery, and an anti-collision bramble 34 is integrally connected to the side of the battery cover 3 close to the battery; the battery mounting ports 31 are distributed in an array, and the batteries are inserted into the battery mounting ports 31 accordingly. The battery mounting ports 31 play a certain role in fixing and protecting the batteries. The batteries can be fixed from both the upper and lower directions, so that the batteries can be installed more firmly, and the rectangular arrangement saves space in the vehicle and makes the battery arrangement more beautiful.

[0022] The water cooling plate installation groove 32 is opened below the battery installation opening 31, and the water cooling plate installation groove 32 connects the battery installation openings 31 of each row in pairs; it is used to install water cooling plates at both ends of the battery, which helps to dissipate heat at both ends of the battery, and the water cooling plates are arranged parallel to the longer sides of the rectangular array, with a large heat dissipation area and good heat dissipation effect. The separate arrangement of each row can ensure that the others can still work normally after one of them is damaged.

[0023] The anti-collision bramble 34 is arranged between the two water-cooling plate mounting grooves 32. When the battery cover 3 fixes the battery from both ends of the battery, the anti-collision bramble 34 can leave a certain gap between the two batteries to prevent the batteries from colliding with each other. At the same time, the anti-collision bramble 34 can strengthen the overall structure of the battery cover 3, so that the battery cover 3 is not easily damaged, and the battery inside the shell 1 can be better protected. The gap between the batteries is opposite to the heat dissipation facility 2, which is convenient for air flow at both ends. The gap can be divided into air duct 1 21 and air duct 2 22 matching the anti-collision bramble 34, wherein the air duct 1 21 is smaller than the air duct 2 22, and the air duct 1 21 and the air duct 2 22 are alternately arranged. When air passes through the air duct 1 21, the air duct 1 21 will be pressurized due to the small space, and the air will flow to the air duct 2 22 faster. At this time, the air flowing in from both sides will generate convection in the air duct 2 22, further accelerating the air flow rate, which can evenly dissipate heat on the battery surface, and cooperate with the water-cooling plate for better heat dissipation effect and more uniform heat dissipation.

[0024] A column 11 matching the snap-in groove 33 is provided on the inner wall of the shell 1, which strengthens the structure of the shell 1, makes the shell 1 not easy to be damaged, and can better protect the battery. The snap-in groove 33 can be snapped with the column 11 to support the battery covers 3 on both sides of the battery, so that the battery covers 3 on both sides are installed more firmly, which is beneficial to protecting the shell 1; a filling groove 35 is opened between the battery cover 3 and the shell 1, and some buffer materials such as buffer cotton, polyethylene foam, rubber, etc. can be filled into the filling groove 35 before installation, which can play a certain buffering role, extend the service life of the battery cover 3, and at the same time better protect the battery.

[0025] The utility model provides a high-voltage electrical appliance protective cover for new energy vehicles. By providing a water-cooling plate mounting groove 32 on a battery cover 3, heat can be dissipated at both ends of a battery. Anti-collision brambles 34 are provided on the battery cover 3 to enhance the structural strength of the battery cover 3 while creating a certain gap between the batteries. Wind at both ends will form convection through the gaps, and heat can be evenly dissipated on the battery surface.

[0026] Working principle:

[0027] The water cooling plate is installed in the water cooling plate installation groove 32, and then the battery is installed in the battery installation port 31. The water cooling plate dissipates heat from both ends of the battery. The air flows in the shell 1, and the battery surface is evenly dissipated when the air passes through the air duct 1 21 and the air duct 2 22.

[0028] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings.
