Description

Technical Field

[0001] This application relates to the field of battery boxes, and in particular to a battery box with a collision detection function. Background Art

[0002] Existing battery box technologies are widely used in fields such as electric vehicles and energy storage systems. Especially in electric vehicles, the battery box is usually installed at the bottom of the vehicle to save space and optimize the vehicle's center of gravity. However, due to this installation position, the battery box is prone to being collided by road bumps, gravel impacts, or other external objects during vehicle driving. Although existing technologies have considered structural strength and impact resistance in the design of the battery box, these protective measures are often limited to physical protection and cannot effectively cope with the complex situations that may be caused after a collision.

[0003] A collision will not only damage the structure of the battery box, but more seriously, it may cause the thermal management system inside the battery to get out of control. Once the thermal management system gets out of control, the battery may overheat, catch fire, or even explode, which poses a great safety threat to vehicle occupants and the surrounding environment. Although existing technologies have physically strengthened the battery box, they are insufficient in dealing with the hidden dangers after a collision. Especially after a collision occurs, it is impossible to monitor and evaluate the damage of the battery in real time, resulting in potential dangers not being discovered and processed in time.

[0004] The main reason for this deficiency is that existing battery box technologies rely too much on passive protection and lack the function of active monitoring. After a vehicle collision, due to the lack of effective detection means, the battery state inside the battery box may not be timely feedback when problems occur, thus corresponding safety measures cannot be taken in time. This passive protection mode not only increases safety hazards, but also makes vehicle maintenance and battery replacement more complex and uncertain.

[0005] Therefore, it is of great significance and value to develop a battery box with a collision detection function. Summary of the Utility Model

[0006] The purpose of this application aims to at least overcome one deficiency existing in the prior art, and provides a battery box with a collision detection function. Collision detection technology is introduced into this battery box, which can obtain the state information of the battery at the first time when a collision occurs, thus providing an important basis for subsequent maintenance and handling. This can not only improve the overall safety of the vehicle, reduce the probability of accidents, but also guarantee the service life of the battery and effectively extend the use cycle of the battery.

[0007] To achieve the above object, the present application discloses a battery box with a collision detection function. The battery box includes a box body, a fixed induction contact plate located on the bottom surface of the box body, a movable induction contact plate spaced opposite to the fixed induction contact plate, an insulating protection plate on the bottom surface of the movable induction contact plate, and a detection component located inside the box body and electrically connected to the fixed induction contact plate and the movable induction contact plate. Among them, the insulating protection plate cooperates with the bottom surface of the box body to block the bottom surface of the box body and form a fully sealed and waterproof detection chamber with the bottom surface of the box body; the fixed induction contact plate and the movable induction contact plate are both installed in the detection chamber, and a plurality of insulating blocks are clamped between the fixed induction contact plate and the movable induction contact plate, so that the fixed induction contact plate and the movable induction contact plate are spaced and physically insulated from each other in the initial state; the movable induction contact plate is spaced from the inner surface of the insulating protection plate, and a coating layer is provided on the inner surface of the insulating protection plate. When the insulating protection plate contacts the movable induction contact plate, a part of the coating layer adheres to the movable induction contact plate; the fixed induction contact plate is physically in contact with the box body and electrically conducts; the detection component includes an induction circuit electrically connected to the fixed induction contact plate and the movable induction contact plate respectively through cables. When the fixed induction contact plate and the movable induction contact plate are in contact and conduct, the induction circuit is triggered; the box body has a base and a panel that cooperates with the base to form a sealed battery chamber.

[0008] In some embodiments, the distance between the fixed induction contact plate and the movable induction contact plate is 10 mm - 15 mm.

[0009] In some embodiments, the distance between the movable induction contact plate and the insulating protection plate is 10 mm - 15 mm.

[0010] In some embodiments, at least the bottom surface of the base of the box body has conductivity.

[0011] In some embodiments, the induction circuit is a conductive induction circuit. The positive or negative pole of the induction circuit is electrically conducted with the fixed induction plate, and the other opposite negative or positive pole is electrically conducted with the movable induction plate; when the fixed induction plate contacts the movable induction plate, the circuit is conducted to trigger the induction function.

[0012] Compared with the prior art, the present application has at least the following beneficial effects:

[0013] 1. High working reliability: By setting the fixed induction contact plate and the movable induction contact plate and clamping insulating blocks between the two, it is ensured that the two remain physically insulated when there is no collision. When a collision occurs, the movable induction contact plate moves to contact the fixed induction contact plate, triggering the induction circuit to achieve precise collision detection.

[0014] 2. Multiple protections and intuitive display: An insulating protection board is provided on the bottom surface of the battery box body, which is spaced and cooperated with the movable induction contact board, providing additional physical protection to prevent accidental triggering. At the same time, the coating layer on the inner surface of the insulating protection board will partially adhere to the movable induction contact board during a collision to visually indicate the collision position.

[0015] The beneficial effects listed above do not exhaust all the advantages. Other potential beneficial effects and detailed technical implementation manners will be further disclosed in the embodiments or other description parts of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] As used in this specification, the singular forms "a," "an," "said," and "the" include the plural forms unless otherwise expressly stated. The words "include," "comprise," and "contain" as used in this specification indicate the presence of the claimed features, but do not exclude the presence of one or more additional features. The word "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items. Example

[0024] like Figures 1 to 3 As shown, this embodiment discloses in detail a battery box with a collision detection function. The battery box has a sophisticated structure and a careful design, and is intended to provide efficient and accurate collision detection and protection functions.

[0025] Its main structural components include the housing 1, fixed inductive contact plate 2, movable inductive contact plate 3, insulating protective plate 4, detection assembly 5, detection chamber 6, insulating block 7, coating layer 8, base 9, and panel 10. Through rational structural design and high-quality material selection, the battery box ensures timely detection and response to external impacts, greatly improving battery safety and overall system reliability.

[0026] Specifically, the battery box body 1 comprises a base 9 and a panel 10, which are tightly connected by a sealing structure to form a highly sealed battery compartment. This sealing structure generally includes at least one sealing ring, which not only effectively prevents the external environment from affecting the battery, such as moisture, dust, and temperature fluctuations, but also ensures the overall structural strength and durability of the battery box.

[0027] In applications such as electric vehicles and industrial equipment, battery boxes may face various harsh environments, so this sealing structure is critical to protecting the batteries.

[0028] In this embodiment, the fixed inductive contact plate 2 is fixedly mounted on the bottom surface of the housing 1 and is electrically connected to the bottom surface of the housing 1. The fixed inductive contact plate 2 is designed using high-quality conductive metal materials, such as copper or aluminum alloy, to ensure excellent conductivity and mechanical stability during long-term use. Precision machining and installation ensure that the contact plate will not loosen or fail due to vibration or external forces during use, thereby providing reliable electrical connection and signal transmission.

[0029] The movable induction contact plate 3 is arranged opposite to the fixed induction contact plate 2, separated by a number of insulating blocks 7, and maintained at an interval distance of 10 mm - 15 mm. These insulating blocks 7 are made of high-strength insulating materials and can withstand various impacts and pressures that may occur during the transportation or operation of the battery box, ensuring that physical insulation is maintained between the movable induction contact plate 3 and the fixed induction contact plate 2 under normal conditions. This design greatly reduces false triggering caused by slight vibrations or non-impact external forces, guaranteeing the detection accuracy of the battery box and the stability of the system.

[0030] The insulating protection plate 4 is fixed to the bottom surface of the movable induction contact plate 3. Its main function is to cover and protect the bottom surface of the box body 1 and form an independent detection chamber 6 with the bottom surface. The design of this detection chamber 6 enables the fixed induction contact plate 2 and the movable induction contact plate 3 to work in a relatively enclosed environment, thereby reducing the influence of external factors (such as moisture, dust, etc.) on the detection accuracy. The insulating protection plate 4 is made of high-strength insulating materials such as epoxy resin or polyimide, which not only provides excellent electrical insulation performance but also has good wear resistance and corrosion resistance, capable of protecting the internal structure from damage for a long time.

[0031] The detection component 5 includes a highly sensitive induction circuit and related controllers, which are electrically connected to the fixed induction contact plate 2 and the movable induction contact plate 3 through precise wiring. When the battery box 1 is subjected to an external impact, the movable induction contact plate 3 moves towards the fixed induction contact plate 2 under the action of pressure and finally contacts the fixed induction contact plate 2, and the induction circuit is immediately turned on. At this time, the detection component 5 receives the induction signal and immediately reacts, starting a preset response mechanism, such as sending an alarm signal to the central control system, activating the protection program of the battery (such as cutting off the power supply, reducing the working current, or starting the cooling system).

[0032] To further improve the detection accuracy, a coating layer 8 is specially designed on the inner surface of the insulating protection plate 4. The coating layer 8 will partially adhere to the movable induction contact plate 3 during a collision, and this adhesion behavior directly indicates the collision position, especially being significantly helpful during the inspection process after a collision.

[0033] During actual use, when the battery box encounters an external force, the movable induction contact plate 3 will first move towards the fixed induction contact plate 2 and make contact and conduction under sufficient pressure, triggering the detection component 5 to perform an intermediate response. At this time, the system will identify it as a severe collision and trigger high-level protection measures, such as completely cutting off the battery power supply or starting an emergency shutdown program, to ensure the safety of the battery and related equipment.

[0034] In summary, through scientific and reasonable design and combined with high-quality material selection, the battery box of this embodiment has successfully achieved efficient collision detection and protection functions. Its structure is designed compactly, which is convenient for manufacturing and maintenance, and is applicable to various application scenarios that require high-security battery protection, including but not limited to electric vehicles, power tools, industrial equipment, etc. By using this embodiment, users can effectively reduce battery damage caused by collisions and potential safety hazards, thereby significantly improving the overall safety performance and user experience of the product.

[0035] Although the exemplary embodiments of the present disclosure have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included within the protection scope of the present disclosure defined by the claims.
