Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A power battery fault alarm device includes a placement box 1, with rotating doors 2 rotatably connected to both sides of the placement box 1. A warning light 4 and a controller 5 are fixedly mounted on the top of the placement box 1. A fan 3 is also provided on the top of the placement box 1. Connectors 6 are provided on both outer walls of the placement box 1. Clamping plates 7 are fixedly mounted on the outer walls of the rotating doors 2. Positioning plates 19 are fixedly mounted on both inner walls of the placement box 1. A circular hole 16 is opened on the top of the positioning plate 19, and an adjusting screw 17 is threadedly connected to the inner wall of the circular hole 16. A crank handle 20 is fixedly mounted on the top of the box 1. A limit rod 13 is fixedly mounted on the bottom of the inner wall of the box 1. A return spring 14 is sleeved on the outer wall of the limit rod 13. The top of the return spring 14 abuts against a lifting platform 15. A limit hole 18 is opened on the top of the lifting platform 15. The body 12 is placed on the top of the lifting platform 15. An elastic plate 8 is provided on the inner wall of the box 1. An electrode 9 is fixedly mounted on the top of the elastic plate 8. A fixing rod 10 is fixedly mounted on the top of the inner wall of the box 1. An electrode 11 is fixedly mounted on the bottom of the fixing rod 10.

[0023] In the above structure, through the arrangement of the placement box 1, rotating door 2, fan 3, warning light 4, controller 5, main body 12, and lifting platform 15, when the main body 12 is powered on, a chemical reaction occurs inside, producing gas that causes the main body 12 to deform. The main body 12 then applies pressure to the elastic plate 8, causing electrode 9 on the elastic plate 8 to adhere to electrode 11. This causes the warning light 4 to automatically light up under the control of the controller 5, thus alerting surrounding personnel that the main body 12 has bulged, thereby improving the practicality of the device.

[0024] In a preferred embodiment, the top of the placement box 1 is provided with an installation hole, and the fan 3 is disposed in the installation hole. There are two fans 3, and the two fans 3 are symmetrically distributed along the inner wall of the placement box 1.

[0025] In the above structure, the two fans 3 are designed so that when the main body 12 outputs current during operation, it will dissipate heat. At this time, the two fans 3 are used to dissipate heat from the main body 12, thereby accelerating the heat dissipation speed of the main body 12. This ensures that the main body 12 can operate for a long time without heat accumulation, improving the practicality of the device and the safety during operation.

[0026] In a preferred embodiment, the bottom end of the adjusting screw 17 is rotatably connected to the top of the lifting platform 15, and the inner wall of the limiting hole 18 is slidably connected to the outer wall of the limiting rod 13.

[0027] In the above structure, the limiting rod 13 and the limiting hole 18 allow the user to adjust the height of the lifting platform 15 by turning the handle 20 during use. This makes it easier for the user to place the body 12 of different thicknesses on the lifting platform 15, thus facilitating the user to test and install different models of body 12, thereby increasing the scope of application of the device.

[0028] In a preferred embodiment, the elastic plate 8 is made of copper, and the bottom of the elastic plate 8 is attached to the top of the body 12.

[0029] In the above structure, the metallic copper has good ductility, which can ensure that the body 12 will stick tightly to the elastic plate 8 after the bulging phenomenon occurs. This will cause the elastic plate 8 to be squeezed and the electrode 9 to move upward, thereby achieving the effect of electrode 9 sticking to electrode 11 and causing the warning light 4 to light up to provide a warning, thus ensuring the normal operation of the device.

[0030] In a preferred embodiment, through grooves are provided on both outer walls of the elastic plate 8, and the positions of the through grooves correspond to the positions of the fan 3.

[0031] In the above structure, the through-slot structure allows the fan 3 to blow air during operation, creating cool air and thus enabling the fan 3 to effectively dissipate heat from the body 12. Combined with the attached... Figure 2 It is known that when hot air is blown, it will flow out from the gap between the rotating door 2 and the placement box 1 to the outside of the placement box 1, thereby achieving the effect of auxiliary heat dissipation for the main body 12.

[0032] In a preferred embodiment, the end of the clamp 7 is attached to the outer wall of the body 12, and the body 12 is fixedly connected to the lifting platform 15 through the clamp 7.

[0033] In the above structure, through the structure of the main body 12 and the clamping plate 7, the user can expose the lifting platform 15 inside the placement box 1 by rotating the rotating door 2, and then place the main body 12 directly on the lifting platform 15. The rotation of the rotating door 2 is used to make the clamping plate 7 fit against the outer wall of the main body 12, thereby ensuring that the device is fixed to the main body 12 during operation, thus improving the stability of the main body 12 during operation.

[0034] In a preferred embodiment, mounting plates are fixedly mounted on both outer walls of the placement box 1, and the outer walls of the mounting plates are rotatably connected to the outer walls of the rotating door 2.

[0035] In the above structure, the rotating door 2 allows the user to place the main body 12 by rotating the door 2, and also allows the user to easily turn the handle 20 to adjust the height of the lifting platform 15, ensuring the normal use of the device.

[0036] In a preferred embodiment, electrode 2 11 is electrically connected to electrode 1 9, warning light 4, and controller 5, respectively, and fan 3 is electrically connected to controller 5 and body 12, respectively.

[0037] In the above structure, through the fan 3, controller 5 and body 12, the automatic alarm operation can be completed by the contact of electrode 1 9 and electrode 2 11 during operation, so that the user does not need to observe the body 12 by eye to complete the detection operation, which improves the intelligence of the device. The user can also control the fan 3 through controller 5 to make the body 12 subject to the influence of cold air flow, increase the heat loss rate of the body 12, and thus improve the heat dissipation efficiency of the body 12.

[0038] Working principle: First, the user rotates the rotating door 2, then turns the rocker handle 20 to make the adjusting screw 17 drive the lifting platform 15 to rise and fall, thereby adjusting the distance between the elastic plate 8 and the lifting platform 15, which facilitates the user to test and install the body 12 of different sizes. After adjustment, the rotation of the rotating door 2 is used to make the clamping plate 7 fit against the outer wall of the body 12, thereby achieving the effect of auxiliary fixation of the body 12 and improving the stability of the body 12 during operation. When the body 12 outputs current, the bulging of the body 12 causes the elastic plate 8 to be squeezed, causing electrode 1 9 to fit against electrode 2 11, thereby cooperating with the controller 5 to automatically control the warning light 4 to light up, thereby achieving the effect of warning the user and improving the safety of the device during use. At the same time, the operation of the fan 3 blows air out of the body 12 to assist in the heat dissipation of the body 12, thereby accelerating the heat loss rate of the body 12 and improving the heat dissipation efficiency of the body 12.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
