For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] Next, reference will be made to Figure 1 - Figure 8 Describe the power battery throwing device 100 according to the embodiment of the first aspect of the present utility model.

[0036] The design intention of this power battery throwing device 100 is to improve the safety of users in case of emergencies in the power battery usage scenario. Therefore, the application scenarios of the power battery throwing device 100 are very extensive and are not limited to a certain specific type of transportation vehicle. The power battery throwing device 100 is applicable to new energy vehicles and can also be extended to other types of transportation vehicles, such as electric motorcycles, electric buses and even electric ships, etc. Especially in those application scenarios with narrow spaces and high safety requirements, the power battery throwing device 100 can provide a reliable emergency safety guarantee measure.

[0037] As Figure 1As shown, the power battery throwing device 100 according to an embodiment of the present utility model includes: a battery fixing member 10 and a boosting member 20.

[0038] The battery fixing member 10 is used to mount the power battery of the vehicle. The battery fixing member 10 serves as the basic support structure for the power battery, and its internal shape, size, etc. are suitable for mounting the power battery. Optionally, the battery fixing member 10 is made of a high-strength and corrosion-resistant material member. For example, alloy steel or special engineering plastics, etc. Such a material member can ensure that during long-term use, the battery fixing member 10 maintains the structural stability and durability, and can provide stable and reliable daily protection for the power battery.

[0039] As Figure 2 shown, the power battery throwing device 100 further includes a boosting member 20. The boosting member 20 has a first rod body 21 that can be telescoped up and down. The first rod body 21 has a first position, a second position, and a third position. Combining Figure 3 , at the first position, the lower end of the first rod body 21 abuts against the battery fixing member 10 to position the battery fixing member 10. Combining Figure 4 , at the second position, the first rod body 21 rises relative to its position at the first position to disengage from the battery fixing member 10. Combining Figure 5 , at the third position, the first rod body 21 descends relative to its position at the first position to push out the battery fixing member 10.

[0040] The first rod body 21 has the ability to expand and contract in the vertical direction, which improves the operation flexibility and precise control of the boosting rod. When the first rod body 21 is in its initial or first position, its lower end closely fits on the battery fixing member 10, forming a firm and reliable support interface. This tight connection not only ensures that the battery fixing member 10 is stably held in place during daily use, effectively resisting the risk of position deviation or accidental detachment caused by vibrations and bumps that may occur during vehicle driving, but also enhances the structural integrity between the battery fixing member 10 and the boosting rod, providing safety protection for daily use.

[0041] When a throwing action needs to be performed, the boosting member 20 receives an instruction from the vehicle safety management system or the driver, and the first rod body 21 starts to rise from the first position. As the rod body rises, it gradually disengages from direct contact with the battery fixing member 10, thereby releasing the fixing effect on the power battery. During this process, the locking mechanism between the boosting member 20 and the battery fixing member 10 is synchronously unlocked to prepare for the throwing of the power battery.

[0042] Combining Figure 4-5, after the first rod 21 reaches the second position and completes unlocking, it continues to move downward to the third position. In this position, the first rod 21 uses the driving force to smoothly push out the battery fixing member 10. This pushing action is carried out along the vertical direction, which helps to ensure that the power battery can maintain a stable posture during the throwing process and avoid collisions or frictions with surrounding objects.

[0043] Optionally, in some embodiments not shown in the figure, an anti-slip pad is provided on the side of the first rod 21 facing the battery fixing member 10.

[0044] First of all, when the anti-slip pad abuts against the battery fixing member 10, it can significantly enhance the friction between the two, effectively preventing the battery fixing member 10 from shaking due to vibrations, bumps, etc. during vehicle driving. This anti-slip effect protects the battery from physical damage on the one hand, and on the other hand, it also ensures the stable and reliable electrical connection effect between the battery in the battery fixing member 10 and the vehicle power system, avoiding poor electrical contact or interruption caused by battery shaking, thus ensuring the normal operation of the vehicle.

[0045] Secondly, since the material of the anti-slip pad usually has excellent wear resistance and compression resistance, it can withstand the strong thrust from the first rod 21 without being easily damaged. This enables the first rod 21 to push the battery fixing member 10 more smoothly, reducing problems such as difficult pushing or incomplete pushing caused by insufficient friction. At the same time, the anti-slip pad can also buffer the impact on the battery fixing member 10 caused by the thrust to a certain extent, protecting it from damage, thereby extending the service life of the entire power battery throwing device 100.

[0046] According to some embodiments of the present invention, the power battery throwing device 100, as Figure 6 shown, further includes: a positioning member 30, the positioning member 30 has a movable positioning portion 31, and when the first rod 21 is in the first position, the positioning portion 31 cooperates with the battery fixing member 10, and after the first rod 21 is in the second position, the positioning portion 31 is disengaged from the battery fixing member 10.

[0047] During daily use, the positioning portion 31 cooperates with the battery fixing member 10 to position the battery fixing member 10 and prevent its displacement or loosening.

[0048] Specifically, the positioning portion 31 and the first rod 21 cooperate with each other to jointly apply a clamping force to the battery fixing member 10 to ensure effective clamping and positioning of the battery fixing member 10.

[0049] When the first rod 21 is in its first position, that is, the position in close contact with the battery fixing member 10, the positioning portion 31 is also in a state of cooperating with the battery fixing member 10 accordingly. At this time, combined with Figure 1, the positioning part 31 forms a certain mechanical constraint from below the battery fixing part 10. At the same time, the first rod body 21 also applies a certain pressure or thrust to the battery fixing part 10 with its lower end, and together with the positioning part 31, a clamping force is generated on the battery fixing part 10. This clamping force is two-way, with both the constraint from the positioning part 31 and the pressure in the vertical direction from the first rod body 21. The two act together to firmly clamp the battery fixing part 10 in the device.

[0050] It should be noted that when the first rod body 21 is in the second position, the positioning part 31 and the battery fixing part 10 almost simultaneously complete the detachment process. Such a design can shorten the ejection response time of the power battery in case of emergencies such as exceeding the preset temperature. Once the temperature of the battery pack rises abnormally and triggers the ejection mechanism, the rapid movement of the first rod body 21 not only releases the battery fixing part 10, but also creates an unobstructed detachment path for the power battery through the synchronous detachment of the positioning part 31.

[0051] Moreover, this almost synchronous detachment method can accelerate the speed of separating the power battery from the vehicle, reducing the possibility of further damage to the power battery or causing greater safety risks in a high-temperature environment. Once the power battery is successfully detached, the subsequent ejection actions can be seamlessly connected to ensure the efficient execution of the entire emergency handling process.

[0052] Not only that, in some scenarios where the power battery needs to be replaced or maintained, the battery fixing part 10 can also ensure that the battery can be conveniently and quickly removed or installed by detaching from the positioning part 31 and the first rod body 21.

[0053] According to the power battery ejection device 100 of some embodiments of the present invention, the positioning part 31 includes: a positioning support body 311. When the positioning part 31 cooperates with the battery fixing part 10, the positioning support body 311 is located below the battery fixing part 10 to support the battery fixing part 10. When the positioning part 31 is detached from the battery fixing part 10, the positioning support body 311 is arranged to avoid the lower part of the battery fixing part 10.

[0054] In the normal working state, when the positioning part 31 cooperates with the battery fixing part 10, the positioning support body 311 is located below the battery fixing part 10, playing a role of supporting and stably supporting the battery fixing part 10. Such a design can not only effectively prevent the battery from shaking during driving or storage, but also reduce the noise and potential damage risks caused by vibration.

[0055] In addition to the support function, the positioning support body 311 also works together with the first rod body 21 to jointly realize the clamping and fixing of the battery fixing part 10. This clamping method not only enhances the firmness of the fixing, but also improves the adaptability of the power battery ejection device 100, and can cope with battery fixing parts 10 of different heights.

[0056] In some alternative embodiments, such as Figure 6 shown, the positioning portion 31 further includes: a positioning card body 312 provided on the positioning support body 311, and the positioning card body 312 is fitted to the side surface of the battery fixing member 10.

[0057] These positioning card bodies 312 exert a lateral binding force on the battery fixing member 10 from its side.

[0058] For example, in situations such as when the vehicle makes a sharp turn, accelerates or brakes, the power battery may be subjected to a large inertial force, causing a tendency for the battery fixing member 10 to move laterally. The lateral binding force provided by the positioning card body 312 can effectively resist this tendency, ensuring that the battery fixing member 10 remains in a predetermined position, thereby guaranteeing the stability and safety of the power battery.

[0059] Therefore, these positioning card bodies 312, as an additional fixing mechanism, exert a lateral binding force on the battery fixing member 10 from its side, complementing the vertical clamping force of the first rod body 21 to form a dual fixing.

[0060] In addition, optionally, a buffer pad is provided between the positioning card body 312 and the battery fixing member 10. During vehicle driving, when the vehicle encounters uneven road surfaces, certain vibrations will occur. If these vibrations are directly transmitted to the power battery, it may have an adverse impact on its internal structure and electrical connections. By providing a buffer pad between the positioning card body 312 and the battery fixing member 10, part of the vibration energy can be absorbed, reducing the impact of vibrations on the power battery and protecting it from damage. Among them, the buffer pad can be provided on the side of the positioning card body 312 facing the battery fixing member 10, or the buffer pad can be provided on the side wall of the battery fixing member 10 facing the positioning card body 312.

[0061] In some alternative embodiments, in combination with Figure 6 , the positioning member 30 is at least two groups, and the positioning card bodies 312 of the two groups are located on opposite sides of the battery fixing member 10.

[0062] Specifically, the two groups of positioning members 30 are arranged at intervals in the same direction, forming a parallel and symmetric layout. This layout not only ensures the balanced force of the battery fixing member 10 when subjected to external forces, but also improves the stability and reliability of the entire fixing system.

[0063] Each group of positioning members 30 includes two positioning members 30, and these two positioning members 30 are respectively provided on opposite sides of the battery fixing member 10. Such a design enables the battery fixing member 10 to be effectively supported and fixed on both sides, preventing the battery fixing member 10 from shaking and shifting during daily operation.

[0064] Each positioning member 30 includes a positioning card body 312, and these positioning card bodies 312 are adapted to abut against the outer shape of the battery fixing member 10 to ensure that they can closely fit the battery fixing member 10 and provide sufficient clamping force.

[0065] The two positioning card bodies 312 of each group of positioning members 30 work together on opposite sides to jointly clamp the battery fixing member 10 and prevent it from moving.

[0066] In some alternative embodiments, in combination with Figure 7 , a positioning groove 101 is provided on the side surface of the battery fixing member 10. When the positioning portion 31 cooperates with the battery fixing member 10, the positioning card body 312 is located within the positioning groove 101.

[0067] The shape and size of the positioning groove 101 are adapted to match the positioning card body 312 to ensure that the positioning groove 101 and the positioning card body 312 can be perfectly matched. Optionally, the outer diameter dimension of the positioning card body 312 is smaller than the inner diameter dimension of the positioning groove 101. During positioning, the positioning card body 312 can be completely embedded within the positioning groove 101, and through the tight fit of the physical contact surface and the action of friction, a firm clamping of the battery fixing member 10 is achieved.

[0068] Optionally, the positioning groove 101 has relatively distinct boundaries and depth. This can tightly accommodate the positioning card body 312 during cooperation and prevent it from shaking or falling off.

[0069] The positioning groove 101 is located on the side surface of the battery fixing member 10 and is symmetrically arranged on opposite sides to ensure that the battery fixing member 10 can be evenly stressed during the fixing process and improve stability.

[0070] Optionally, the groove surface of the positioning groove 101 is made of a high-strength and wear-resistant material surface. It can be such as alloy steel or aluminum alloy, etc. Or, the groove surface further includes an anti-slip layer or is roughened to increase the friction force with the positioning card body 312 and prevent relative sliding under vibration or impact.

[0071] In some alternative embodiments, a positioning bottom groove 102 connected to the positioning groove 101 is provided on the bottom surface of the battery fixing member 10. The positioning support body 311 can slide along the positioning bottom groove 102. This positioning bottom groove 102 not only serves to position the positioning support body 311 but also can act as a track for the positioning support body 311 to slide during the throwing-off process.

[0072] Exemplarily, when the power battery ejection device 100 is in a non-activated state, the positioning support 311 is firmly embedded in the positioning bottom groove 102 to ensure the stability and safety of the power battery during vehicle driving. Once the power battery ejection device 100 receives a start signal, the positioning support 311 will slide smoothly and orderly along the preset track in the positioning bottom groove 102 in a direction away from the battery fixing member 10. The design of this sliding track not only ensures the rapidity of power battery ejection but also guarantees the stability and controllability of the entire ejection process. The guiding function of the positioning bottom groove 102 enables the positioning support 311 not to deviate from the predetermined track during sliding, thus avoiding ejection failure or safety risks caused by possible direction deviation.

[0073] According to some embodiments of the present utility model, for the power battery ejection device 100, the positioning member 30 includes a driving motor (not shown in the figure), and the output end of the driving motor is connected to the positioning portion 31 to drive the positioning portion 31 to move.

[0074] Specifically, the output end of the driving motor (for example, the shaft of the driving motor or the output shaft of the reducer) is connected to the positioning portion 31 through an appropriate transmission device such as a coupling, gear, or belt. This connection method can ensure that the power output by the motor can be accurately transmitted to the positioning portion 31 and drive it to move along the predetermined track.

[0075] When the motor starts, the rotational power generated by it is transmitted to the positioning portion 31 through the transmission device. After receiving the power, the positioning portion 31 will move along the preset path or track, such as translation.

[0076] Optionally, the rotation speed and rotation direction of the driving motor can be adjusted according to the actual situation to achieve precise control of the movement of the positioning portion 31. For example, by adjusting the rotation speed of the driving motor, the positioning portion 31 can move at a predetermined speed.

[0077] For example, when the temperature of the power battery exceeds the preset safety threshold and it is necessary to urgently start the power battery ejection device 100, the driving motor starts and responds quickly, and adjusts its rotation speed and rotation direction according to the preset control logic to achieve the control of the positioning portion 31.

[0078] In this process, the output end of the driving motor is directly connected to the positioning portion 31, and by transmitting linear thrust, the positioning portion 31 is moved at a predetermined speed, thereby releasing the constraint on the battery fixing member 10.

[0079] After the positioning portion 31 is separated from the battery fixing member 10, the power battery ejection device 100 will enter the next stage of performing the ejection action.

[0080] According to some embodiments of the present utility model, for the power battery ejection device 100, such asFigure 1 , Figure 8 As shown in Figure 8 , the boosting member 20 is disposed above the battery fixing member 10, and there are multiple boosting members 20 which are distributed in multiple rows and columns.

[0081] The boosting member 20 is arranged above the battery fixing member 10 and is distributed in multiple rows and columns to ensure that balanced and powerful driving force can be provided when needed.

[0082] Specifically, the boosting member 20 is located above the fixed battery, so that the first rod 21 can directly apply a downward driving force to the battery fixing member 10. When it is necessary to throw off the power battery, the first rod 21 acts quickly after receiving the start signal, and uses its powerful thrust and the gravity of the battery itself to form a resultant force (when the vehicle is in a general state), thereby accelerating the process of the battery fixing member 10 vertically leaving its original position. This not only improves the throwing-off efficiency, but also ensures that the power battery can be safely removed in the shortest time.

[0083] Considering extreme situations that the vehicle may encounter, such as rollover or flipping. In these situations, the battery fixing member 10 may be affected by gravity from different directions, but the arrangement position of the boosting member 20 is above the battery fixing member 10, so that the driving force of the first rod 21 can overcome these gravity effects and can push the battery fixing member 10 out of the using position, thus separating from the vehicle. With such a setting, the power battery can be safely thrown off in various postures of the vehicle, greatly improving the overall safety and reliability of the vehicle.

[0084] According to some embodiments of the present invention as Figure 8 shown, for the power battery throwing-off device 100, the boosting member 20 is disposed above the battery fixing member 10, and the top of the battery fixing member 10 is provided with a positioning hole 12, and the lower end of the first rod 21 is located in the positioning hole 12 at the first position.

[0085] Then, when the first rod 21 is in its first position, the lower end of the first rod 21 can pass through and be located in these positioning holes 12 and abut against the power battery in the battery fixing member 10. When the first rod 21 passes through the positioning hole 12 on the battery fixing member 10 to position the power battery, not only can the position of the battery fixing member 10 be accurate, but also the position of the power battery in the vehicle can be ensured to be accurate, thereby improving the wiring reliability between the power battery and other components of the vehicle.

[0086] As Figure 7 shown, for the power battery throwing-off device 100 according to some embodiments of the present invention, it further includes: a buffer member 40 provided at the bottom of the battery fixing member 10.

[0087] It is known that when the power battery triggers the ejection mechanism due to overheating or fire, it often leaves the vehicle body at a faster speed and is accompanied by a greater impact force. At this time, the buffer 40 located at the bottom of the battery fixture 10 can effectively absorb and disperse this part of the impact force, thereby mitigating the huge impact generated when the power battery directly hits the ground or other hard objects. This buffering effect not only protects the power battery itself, reduces the risk of damage or further combustion caused by the impact, but also reduces the potential damage to the surrounding environment and other vehicle components.

[0088] The provision of the buffer member 40 not only helps to reduce secondary disasters caused by damage to the power battery, such as electrolyte leakage, fire spread, etc., but also provides more convenient conditions for subsequent emergency treatment and battery recycling.

[0089] In some optional embodiments, the buffer member 40 is made of a material with high energy absorption and impact resistance, such as rubber, foam plastic or composite material, etc. These materials can be deformed quickly when impacted, converting kinetic energy into internal energy, thereby effectively absorbing the impact force.

[0090] According to some embodiments of the present invention, the power battery ejection device 100 is combined with Figure 1 , Figure 3 - Figure 5 , Figure 7 - Figure 8 The battery fixing member 10 is a frame, the buffer members 40 are multiple and arranged in multiple rows and columns, and the buffer members 40 are buffer pads.

[0091] By constructing the battery fixing member 10 as a frame, it is convenient to connect and fix the battery fixing member 10 to the vehicle chassis or other fixed structures, and a stable supporting platform can be provided for the power battery.

[0092] These buffer pads are arranged in multiple rows and columns to cover multiple areas under the battery fixing member 10. This layout ensures that the power battery can be fully buffered and protected when it is separated from the vehicle body from multiple directions or angles, thereby improving the effective protection of the power battery.

[0093] According to the power battery ejection device 100 of some embodiments of the present invention, the booster 20 is a hydraulic rod.

[0094] It is worth noting that the hydraulic rod can provide a stable and controllable thrust, which is very important for the power battery ejection device 100 that needs to accurately control the ejection process. By adjusting the hydraulic pressure in the hydraulic system, the extension speed and strength of the hydraulic rod can be more accurately controlled, thereby ensuring that the power battery can be smoothly and accurately separated from the vehicle body.

[0095] Secondly, the hydraulic rod has high load-bearing capacity and durability. Since the power battery itself is relatively heavy, the boosting member 20 needs to have sufficient load-bearing capacity to overcome its gravity and push it to move. The hydraulic rod can withstand large loads and maintain stable operation for a long time, ensuring reliable execution of the ejection task in case of emergency.

[0096] Specifically, in the power battery ejection device 100, the hydraulic rod is usually connected to the vehicle control system and operates according to preset instructions or sensor signals. When it is detected that the power battery is overheated or needs to be ejected urgently, the vehicle control system sends a start signal to the hydraulic rod.
