Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, in particular to a battery device with a protection structure. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. In the 1970s, due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal had very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] When applying for the present invention, the applicant found through searching that a Chinese patent disclosed a "lithium battery device with a charging protection structure", and its application number is "CN214542431U". The patent mainly detects the charging status of the lithium battery body through a sensor. When the sensor detects that the charging of the lithium battery body is completed, the motor and the threaded rod are coordinated to start the motor to drive the threaded rod to rotate, so that the L-shaped block drives the wire to move, thereby avoiding overcharging of the lithium battery body and preventing the lithium battery body from overheating, thereby avoiding damage to the interior of the lithium battery body and improving the use effect of the lithium battery body. However, the lithium battery may be subjected to external impact during use, thereby causing damage to the internal structure of the device, and the device lacks consideration in this regard. Therefore, according to the applicant's invention, a device is invented that can well protect the internal structure of the device from damage against external impact, thereby solving the problem that the internal structure of the battery is damaged and cannot be used due to external impact during use. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies of the prior art, the present invention provides a battery device with a protective structure, which solves the problem that the internal structure of the battery is damaged and thus cannot be used due to external impact during use.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a battery device with a protective structure, comprising a device bottom shell, the inner wall of the device bottom shell is threadedly connected with a fixing screw, the outer wall of the fixing screw is threadedly connected with a device top shell, the outer wall of the fixing screw is threadedly connected with a fixing nut, the top of the device top shell is rotatably connected with a lifting handle, the lower surface of the inner wall of the device bottom shell is fixedly connected with a cooling and stabilizing mechanism, the top of the cooling and stabilizing mechanism is fixedly installed with a lower battery box, the inner wall of the lower battery box is fixedly connected with a supporting mechanism, the outer wall of the supporting mechanism is fixedly connected with an upper battery box, and the outer wall of the upper battery box is provided with a collision reduction mechanism. The device seals the bottom shell and the top shell of the device through multiple fixing screws and fixing nuts, thereby ensuring the airtightness of the device, thereby preventing external dust and the like from entering the device and damaging the internal structure, thereby extending the service life of the device. The lifting handle facilitates the transportation of the device, thereby improving the transportation rate of the device. The cooling and stabilizing mechanism reduces the impact of the bottom of the device on the internal structure of the device when it is vibrated, thereby extending the service life of the device. The cooling plate therein has a cooling effect, thereby adjusting the working temperature of the device, thereby ensuring the working environment of the device, extending the service life and use effect of the device. The supporting mechanism supports the upper and lower double-layer structures, increasing the space utilization rate of the device. The collision reduction mechanism protects the top of the device, so that when the top of the device is subjected to external force, the impact of external force on the internal components of the device can be reduced, thereby extending the service life of the device.

[0008] Preferably, the collision reduction mechanism includes a protective plate, a vertical plate, a rotating plate, a horizontal plate, a support frame, a sliding groove, a slider, a sliding rod, a fixed sleeve, a spring, and a rubber pad. The protective plate is fixedly connected to the inner wall of the top shell of the device, the vertical plate is fixedly connected to the side of the protective plate close to the upper battery box, the rotating plate is rotationally connected to the top of the vertical plate, the horizontal plate is rotationally connected to one end of the rotating plate, and the support frame is fixedly connected to the top of the upper battery box. The protective plate can reduce the external force on the side of the device, thereby extending the service life of the device. The vertical plate, the rotating plate, and the horizontal plate enable the top of the device to play a certain supporting and buffering role when it is hit by an impact that causes the top shell of the device to deform, thereby improving the impact resistance of the device. When the impact force is too large, the deformation of the top shell of the device will be stopped by the support frame, ensuring that the external impact force will not directly act on the battery cells inside the device, thereby extending the service life of the device.

[0009] Preferably, the sliding groove is formed at the bottom of the rotating plate, the slider is slidably connected to the inner wall of the rotating plate, and the sliding rod is rotatably connected to the inner wall of the slider. The connection between the rotating plate and the slider and between the slider and the sliding rod prevents the components from breaking when the top of the device top shell is suddenly hit strongly, and the active connection makes the buffering smoother, thereby increasing the buffering effect between the devices.

[0010] Preferably, the sliding rod is slidably connected to the inner wall of the fixed casing, the fixed casing is fixedly connected to the top of the upper battery box, the spring is fixedly connected to the bottom of the sliding rod, the rubber pad is fixedly connected to the lower surface of the inner wall of the fixed casing, and the spring is fixedly connected to the top of the rubber pad. When the spring is impacted by the outside world, the external force can be first converted into deformation, and the external force is weakened to a certain extent in this process. Then, when the spring converts the deformation into impact force, it will be weakened again, mainly relying on the rubber pad at the bottom to weaken the external force. If there is any unweakened force, the spring will be deformed again, and then the conversion will be repeated, and the external force will be gradually reduced, thereby protecting the internal structure of the device, increasing the service life of the device, and the ability to resist the impact of external forces.

[0011] Preferably, the support mechanism includes a support plate, a first fixing groove, a connection frame, and a second fixing groove. The outer wall of the lower battery box is provided with a first fixing groove, and the outer wall of the upper battery box is provided with a second fixing groove. The provision of the first fixing groove and the second fixing groove reduces the width required for the device, thereby increasing the space utilization rate of the device.

[0012] Preferably, the support plate is fixedly connected to the inner wall of the lower battery box, and the support plate is fixedly connected to the inner wall of the upper battery box. The support plate supports the upper battery box and the lower battery box, so that the distance between the upper battery box and the lower battery box is stably maintained at a certain length, which can ensure the electrical safety creepage clearance and increase the stability of the device.

[0013] Preferably, the connection frame is fixedly connected to the bottom of the upper battery box, the connection frame is fixedly connected to the inner wall of the device bottom shell, and the connection frame is fixedly connected to the outer wall of the support plate. The connection frame supports the upper battery box, ensures the stability of the upper and lower double-layer structure, reduces the force borne by the support plate, thereby reducing the loss between components and extending the service life of the device.

[0014] Preferably, the cooling and stabilizing mechanism includes a fixing frame, a shock-absorbing pad, a support rod, and a cooling plate. The fixing frame is fixedly connected to the lower surface of the inner wall of the bottom shell of the device, and the shock-absorbing pad is fixedly connected to the top of the fixing frame. The lower battery box is fixed to the fixing frame by bolts, and the fixing frame is firmly fixedly connected to the lower surface of the inner wall of the bottom shell of the device, so that the lower battery box can effectively resist impact and vibration. The shock-absorbing pad can reduce the impact of external vibration on the battery installed inside the lower battery box, thereby enhancing the device's ability to resist external impact and vibration.

[0015] Preferably, the support rod is fixedly connected to the outer wall of the fixed frame, and the cooling plate is fixedly connected to the lower surface of the inner wall of the bottom shell of the device. The support rod strengthens the firmness of the fixed frame, thereby improving the impact resistance of the device, and the cooling plate can cool down the inside of the device, thereby preventing the device from working poorly due to the environment, or preventing the internal structure of the device from being damaged.

[0016] Working principle: when the device is to be transported, pull up the lifting handle and then lift the device to a suitable position. When the top of the device is impacted, the vertical plate, rotating plate and horizontal plate will first support the top of the top shell of the device when the top of the device is impacted to cause the top shell of the device to deform, and rely on springs and rubber pads to alleviate the impact. Then when the impact is over, the spring will release the absorbed force, and the rubber pad will absorb the absorption part and the sliding rod, slider and rotating plate through the movement. When the impact on the top of the device is large enough, the support frame will provide strong support to avoid damage to the battery cells inside the upper battery box, thereby playing a protective role. When it is detected that the temperature inside the device exceeds a certain value, the cooling plate will be activated to cool the device to protect the device. When the bottom of the device is vibrated or impacted, due to the fastening connection between the lower battery box and the fixed frame and the lower surface of the inner wall of the bottom shell of the device, the internal structure of the device will not shake relative to the bottom shell of the device, thereby enhancing the device's ability to resist vibration and impact.

[0017] (III) Beneficial effects

[0018] The present invention provides a battery device with a protective structure. It has the following beneficial effects:

[0019] 1. The protection plate can reduce the external force on the side of the device, thereby extending the service life of the device. The vertical plate, rotating plate, and horizontal plate enable the top of the device to play a certain supporting and buffering role when it is hit by the impact that causes the top shell of the device to deform, thereby improving the impact resistance of the device. When the impact force is too large, the deformation of the top shell of the device will be stopped by the support frame, ensuring that the external impact force will not directly act on the battery cell inside the device, thereby extending the service life of the device. The connection relationship between the rotating plate and the slider and the slider and the sliding rod prevents the component from breaking when the top of the top shell of the device is suddenly hit strongly. The active connection relationship makes the buffering smoother, thereby increasing the buffering effect between the devices. When the spring is impacted by the outside world, the external force can be converted into deformation first. In this process, the external force is weakened to a certain extent, and then when the spring converts the deformation into impact force, it will be weakened again, mainly relying on the rubber pad at the bottom to weaken the external force. If there is any unweakened force, the spring will be deformed again, and then the conversion between them will be repeated, and the external force will be gradually reduced, thereby protecting the internal structure of the device, increasing the service life of the device, and the ability to resist the impact of external forces.

[0020] 2. The opening of the first fixing groove and the second fixing groove reduces the required width of the device, thereby increasing the space utilization rate of the device. The support plate supports the upper battery box and the lower battery box, so that the distance between the upper battery box and the lower battery box is stably maintained at a certain length, which can ensure the electrical safety creepage clearance and increase the stability of the device. The connecting frame supports the upper battery box, ensures the stability of the upper and lower double-layer structure, reduces the force borne by the support plate, thereby reducing the loss between components and extending the service life of the device.

[0021] 3. The lower cell box is fixed to the fixing frame by bolts, and the fixing frame is firmly fixed to the lower surface of the inner wall of the bottom shell of the device, so that the lower cell box can effectively resist impact and vibration. The shock-absorbing pad can reduce the impact of external vibration on the cells installed inside the lower cell box, thereby enhancing the device's ability to resist external impact and vibration. The support rod strengthens the firmness of the fixing frame, thereby improving the device's impact resistance, and the cooling plate can cool the inside of the device, thereby avoiding poor working performance of the device due to the environment, or damage to the internal structure of the device.
