Description

Technical Field

[0001] This invention relates to the field of battery packs, specifically a power battery assembly for new energy vehicles. Background Technology

[0002] Electric vehicles are vehicles that use onboard power sources to drive their wheels with electric motors and meet all road traffic and safety regulations.

[0003] The onboard power source here is generally a power battery, which is a traditional battery pack structure;

[0004] Onboard power supplies provide electrical energy to the drive motor of an electric vehicle. The motor converts the electrical energy into mechanical energy. The most widely used power source for onboard power supplies is lead-acid batteries. However, with the development of electric vehicle technology, lead-acid batteries have been gradually replaced by other types of batteries due to their low energy, slow charging speed, and short lifespan.

[0005] The power sources currently under development mainly include sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, and fuel cells, and these batteries are usually placed on the chassis of a car via corresponding battery carriers.

Detailed Implementation

[0033] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0034] A power battery assembly for new energy vehicles includes a battery support frame 1 and a battery support bracket 4. The battery support bracket 4 is provided with a sealed spacer housing 5. The battery support bracket 4 is connected to the battery support frame 1 through an adjustment device. This invention discloses a power battery assembly for new energy vehicles. Through the combined use of the battery support frame 1, the battery support bracket 4 and the adjustment device, the invention can facilitate the rapid replacement of the vehicle battery.

[0035] Specifically, the power battery assembly disclosed in this invention is mainly used in new energy vehicles. It mainly includes a battery carrier 1, which is mounted on the chassis and serves as a fixed component. A battery support frame 4 is provided on the battery carrier 1. The battery support frame 4 serves as a connector in subsequent use, facilitating the connection of the battery and the installation of the battery on the battery carrier 1. In addition, a sealing spacer housing 5 is provided on the battery support frame 4, which is used to load the battery and facilitates the arrangement of the battery on the battery support frame 4. Furthermore, in this invention, the battery support frame 4 is connected to the battery carrier 1 through an adjustment device. The adjustment device allows the battery support frame 4 to move longitudinally and laterally, thereby facilitating the separation and installation of the battery support frame 4 and the battery carrier 1, and subsequently facilitating the replacement of the battery and battery pack.

[0036] In this invention, the adjustment device includes a longitudinal adjustment device and a lateral adjustment device. The longitudinal adjustment device is arranged on the battery support frame 1, and the battery support frame 1 is connected to the lateral adjustment device through the longitudinal adjustment device. The lateral adjustment device is connected to the battery support bracket 4. In this invention, the longitudinal adjustment device is used to change the distance between the battery support bracket 4 and the battery support frame 1 in the longitudinal direction. The lateral adjustment device enables the battery support bracket 4 to move laterally, allowing the battery support bracket 4 to be offset below the battery support frame 1. At the same time, it makes it easy for the battery support bracket 4 to detach from the battery support frame 1, enabling the battery support bracket 4 carrying the battery to be quickly loaded, unloaded, and replaced as a whole.

[0037] Furthermore, the longitudinal adjustment device in this invention includes multiple longitudinal adjustment sections. The longitudinal adjustment sections facilitate the limitation of the longitudinal position of the battery support frame 4. Specifically, each longitudinal adjustment section includes a vertical guide frame mounted on the battery support frame 1. The vertical guide frame has a spring engagement groove. The vertical guide frame and the spring engagement groove form a guiding connection mechanism, and the spring engagement groove also serves as a hanging groove later, facilitating the subsequent arrangement of the battery support frame 4. Additionally, each longitudinal adjustment section is connected to a transverse guide rail. The transverse guide rail includes a lifting support frame 3. The lifting support frame 3 acts as a bridge, facilitating the arrangement and placement of subsequent components. Furthermore, the lifting support frame 3 has a bridging portion. The bridge connection facilitates the connection between the transverse guide rail and the longitudinal adjustment section. Specifically, in this invention, each bridge connection includes a vertical slider 301 mounted on the lifting support frame 3, and a balancing traction block is mounted on the vertical slider 301. The balancing traction block is engaged in a spring fitting groove. This arrangement facilitates the engagement of the transverse guide rail on the longitudinal adjustment section. A locking mechanism is also provided on the vertical guide frame. The locking mechanism can lock the relative positions of the transverse guide rail and the longitudinal adjustment section, thereby locking the position of the battery support frame 4. The locking mechanism can use a pin mechanism, as long as it can lock the vertical slider 301 and the vertical guide frame. Alternatively, the structure described below can also be used.

[0038] Furthermore, in this invention, locking mechanisms are provided at both the upper and lower ends of the vertical guide frame; each locking mechanism includes a locking sleeve 202 disposed on the vertical guide frame, a locking protrusion 204 disposed inside the locking sleeve 202, a locking spring disposed at the end of the locking protrusion 204 away from the spring engagement groove, and an unlocking electromagnet disposed at the end of the locking spring away from the locking protrusion 204; a locking groove 303 is provided on the side of the vertical slider 301, and the locking protrusion 204 and the locking groove 303 cooperate with each other; through this arrangement, the present invention can achieve stable locking between the vertical slider 301 and the vertical guide frame.

[0039] In addition, in this invention, two locking mechanisms are symmetrically arranged at the upper end of the vertical guide frame and two locking mechanisms are also symmetrically arranged at the lower end of the vertical guide frame. The two upper locking mechanisms are used to lock the battery support bracket 4 after assembly, and the two lower locking mechanisms are used to lock the battery support bracket 4 after it moves down.

[0040] Furthermore, in this invention, the lifting support frame 3 is connected to the battery support frame 4 via a guide mechanism. The guide mechanism includes a horizontal guide frame 304 mounted on the lifting support frame 3. The two sides of the lifting support frame 3 are respectively connected to various bridge connecting parts via the horizontal guide frame 304. A horizontal guide slider 403 is provided on the outer surface of the battery support frame 4. The battery support frame 4 is inserted into the horizontal guide groove on the horizontal guide frame 304 via the horizontal guide slider 403. This invention facilitates the connection between the battery support frame 4 and the transverse guide rail by setting up a guide mechanism. In addition, the horizontal guide slider 403 and the horizontal guide frame 304 are slidably connected, which facilitates the subsequent detachment of the battery support frame 4 containing the battery from the transverse guide rail. This facilitates subsequent coordination with the ejection mechanism to achieve rapid detachment of the battery support frame 4 containing the battery from the battery support frame 1 when the battery temperature rises or explodes.

[0041] Furthermore, in this invention, the sealed spacer housing 5 is provided with a battery storage compartment 501, and multiple spacer storage racks 502 are evenly arranged in the middle of the battery storage compartment 501. A temperature sensor 503 is provided on the inner side of the spacer storage rack 502. The upper end of the sealed spacer housing 5 is provided with a contact top plate. The present invention facilitates the placement of battery cells through the arrangement of the sealed spacer housing 5 and the battery storage compartment 501. In addition, each spacer storage rack 502 can hold a battery individually, which facilitates the separate assembly of batteries before subsequent overall assembly. It also serves as a separation and isolation protection function. In addition, a temperature sensor 503 is provided on the inner side of the spacer storage rack 502. The temperature sensor 503 is a detection module used to detect the temperature of the battery, which facilitates subsequent linkage with the locking mechanism to realize the subsequent autonomous separation of the entire power battery assembly.

[0042] Furthermore, in this invention, an ejection mechanism is provided between the sealed spacer housing 5 and the lifting support frame 3. The ejection mechanism includes an ejection part, which includes a side pressure relief pipe 601 disposed on the sealed spacer housing 5. The side pressure relief pipe 601 is connected to the battery storage compartment 501. The side pressure relief pipe 601 is connected to a pneumatic ejection sleeve 6, which is arranged on the lifting support frame 3. The ejection mechanism facilitates the automatic separation of the battery from the vehicle body after spontaneous combustion or explosion, reducing injuries to personnel.

[0043] Furthermore, in this invention, the side pressure relief pipe 601 includes a pressure relief pipe body, and a pressure relief vent is provided inside the pressure relief pipe body; a tapered connecting hole is provided at one end of the pressure relief pipe body near the battery storage compartment 501, and the tapered connecting hole communicates with the pressure relief vent; a sealing mechanism is provided in the connection area between the tapered connecting hole and the pressure relief vent, the sealing mechanism including a pressure relief sealing plug 603 disposed inside the pressure relief pipe body, the pressure relief sealing plug 603 being connected to a sealing spring, the sealing spring pressing the pressure relief sealing plug 603 against the inner side of the tapered connecting hole; a limiting ring rib is provided on the inner wall of the pressure relief vent, and the sealing spring is located away from... One end of the pressure relief sealing plug 603 presses against the limiting ring rib; the maximum outer diameter of the pressure relief sealing plug 603 is smaller than the inner diameter of the pressure relief vent hole; the present invention, through the setting of the side pressure relief pipe 601, when not in use, the sealing mechanism blocks the pressure relief pipe body. When the air pressure in the sealing interval housing 5 increases, the high-pressure gas impacts the pressure relief sealing plug 603 in the sealing mechanism, causing the high-pressure gas flow to leak out, and then impacts the pneumatic ejector sleeve 6; under the action of the reaction force, the sealing interval housing 5 is subjected to lateral thrust, thereby driving the battery support bracket 4 to move laterally, thereby realizing the separation between the battery support bracket 4 containing the battery and the battery carrier 1.

[0044] Furthermore, in this invention, the battery carrier 1 includes a bearing sealing chamber 101; the bearing sealing chamber 101 is provided with a cooling mechanism at its top; the cooling mechanism includes a cooling attachment plate 7 disposed on the top of the bearing sealing chamber 101, the cooling attachment plate 7 being provided with a plurality of fitting protrusions 701; a fitting groove 507 is provided on the contact top plate; the fitting groove 507 and the fitting protrusions 701 cooperate with each other; through this design, the battery carrier 1 and the sealing spacer shell 5 can be mutually positioned, and at the same time, the fitting groove 507 and the fitting protrusions 701 cooperate with each other, increasing the contact area between them, thereby achieving better cooling of the battery pack.

[0045] Furthermore, the cooling plate 7 in this invention is provided with cooling fins; a cooling air duct 703 is horizontally arranged above the cooling plate 7, with an air inlet 704 on one side and an exhaust duct 705 on the other side; the air inlet 704 is connected to the vehicle's air intake structure, and the exhaust duct 705 is connected to the vehicle's exhaust structure; through this design, the battery cooling effect can be optimized. Furthermore, since the vehicle's air intake and exhaust structures are existing structures, this connection arrangement allows air to flow through the cooling air duct 703 when the vehicle is in motion, dissipating heat through the cooling fins to the cooling plate 7, thereby completing the heat dissipation of the battery. The separate heat dissipation structure also facilitates battery installation and removal, making it more convenient to use.

A pressure relief vent 605 is provided at the rear end of the side pressure relief pipe 601.

[0074] Please see Figures 1 to 9Optionally, the support frame uses the battery support frame 1 as the support structure for the corresponding power battery. The battery support frame 1 can be fixedly installed on the chassis of the corresponding vehicle. The battery support frame 1 has a sealed support chamber 101 inside, which can accommodate the battery support frame 4 and the sealed spacer shell 5. The batteries are all loaded in the sealed spacer shell 5 on the battery support frame 4. The battery support frame 4 and the battery support frame 1 are connected by a corresponding sliding connection structure. The battery support frame 4 is set on the lifting support frame 3. Vertical guide frames 2 are provided on the left and right side walls of the support chamber 101. Vertical guide grooves 201 are provided in the middle of the vertical guide frames 2. The lifting support frame 3 is connected to the vertical slider 301. The vertical guide groove 201 is slidably connected, and the dimensions of the vertical slider 301 and the vertical guide groove 201 are matched. Therefore, the lifting support frame 3, the battery support frame 4, and the sealing space housing 5 can move up and down along the vertical sliding structure formed by the vertical slider 301 and the vertical guide groove 201 to adjust the height. This facilitates the removal of the battery structure from the bearing sealing chamber 101 of the battery support frame 1 through the bottom opening 102. At the same time, locking sleeves 202 are provided at both the bottom and top of the vertical guide groove 201, and locking protrusions 204 are fitted into the locking sleeves 202. The locking protrusions 204 and the locking sleeves 202 are nested and slidably connected, and the locking protrusions 204 can be embedded in the locking slots. 303 fixes the position of the vertical slider 301. The locking protrusion 204 and the locking slot 303 are dimensionally matched, so the position of the vertical slider 301 can be locked by the locking protrusion 204. This allows it to be locked when the lifting support frame 3 is raised or lowered as a whole, facilitating the installation and removal of the battery. Simultaneously, a spring engagement groove 206 is provided in the middle of the vertical guide groove 201, and a balance spring 207 is provided in the middle of the spring engagement groove 206. A balance traction block 302 is provided in the middle of the vertical slider 301. The balance traction block 302 is slidably engaged inside the spring engagement groove 206. The bottom end of the balance spring 207 is fixedly connected to the top surface of the balance traction block 302. The top end is fixedly connected to the top end of the spring fitting groove 206, and the traction force of the balance spring 207 is slightly less than the weight of the overall battery lifting structure, so as to facilitate the balance of the weight of the overall battery lifting structure, so as to facilitate the vertical sliding and lifting adjustment of the overall battery structure, thereby facilitating the installation, disassembly and replacement of the battery. The battery support frame 4 is correspondingly provided with a partition bottom plate 401. The partition bottom plate 401 is sized to match the bottom opening 102 and the annular sealing ring 103. After the battery support frame 4 is raised and embedded into the battery support frame 1, the partition bottom plate 401 can seal the bottom opening 102 to maintain the sealing of the bearing sealing chamber 101, prevent external moisture and debris from entering, and improve the overall safety of the support frame.

[0075] Please see Figures 1 to 9Optionally, the support frame uses the vertical guide groove 201 of the vertical guide frame 2 as a vertical sliding guide mechanism, allowing the lifting support frame 3 and the battery support frame 4 on it to move up and down as a whole for installation and disassembly by the battery support frame 1. The battery support frame 4 and the lifting support frame 3 are connected by a horizontal guide slider 403 and a horizontal guide groove 305. The battery support frame 4 is slidably connected to the horizontal guide groove 305 via the horizontal guide slider 403. The horizontal center line of the horizontal guide groove 305 is perpendicular to the vertical center line of the vertical guide groove 201. The dimensions of the horizontal guide slider 403 and the horizontal guide groove 305 are matched. Guide rollers... The dimensions of 404 and the fitting wheel groove 306 are matched, so the battery support bracket 4 as a whole can move horizontally through the horizontal sliding guide structure formed by the horizontal guide slider 403 and the horizontal guide groove 305. Multiple supporting rollers 402 are evenly arranged horizontally at the bottom of the spacer base plate 401. So after the lifting support frame 3 is lowered, the spacer base plate 401 can be supported and guided by the supporting rollers 402, so that the battery support bracket 4 as a whole can be moved backward to disassemble from the lifting support frame 3, or moved forward to be embedded in the lifting support frame 3 for installation. This makes it easier to install, disassemble and replace the battery structure, and makes it more convenient and quick to use.

[0076] Please see Figures 1 to 9Optionally, the battery support frame 4 of the carrier can slide rearward along the horizontal guide groove 305 via the horizontal guide slider 403 to detach from the lifting carrier frame 3, thereby disassembling the sealed spacer housing 5 containing the battery. The carrier frame holds the battery body through the sealed spacer housing 5. The battery storage compartment 501 inside the sealed spacer housing 5 is provided with multiple spacer storage racks 502, each of which can hold the corresponding battery. A temperature sensor 503 is also provided in each rack to monitor the battery temperature. At the same time, side pressure relief pipes 601 are provided on both sides of the front end of the sealed spacer housing 5, and the side pressure relief pipes 601 are connected to the battery storage compartment 501. The connection is equipped with a one-way valve structure consisting of a conical connecting port 602, a pressure relief sealing plug 603, and a sealing spring 604. The pressure relief sealing plug 603 and the conical connecting port 602 are fitted together to seal the conical connecting port 602. When the battery inside the battery storage compartment 501 accidentally explodes, the internal pressure will rise instantly, pushing open the pressure relief sealing plug 603, allowing the high-pressure gas inside to be discharged through the side pressure relief pipe 601 to the sealed spacer housing 5, preventing further explosion. At the same time, the temperature sensor 503 and the unlocking electromagnet 205 in the locking sleeve 202 are linked together, and the temperature sensor 503 can be used to unlock the electromagnet 205. 03 controls the on / off circuit of the unlocking electromagnet 205. When the battery experiences abnormally high temperature, the temperature detector 503 detects this and energizes the unlocking electromagnet 205 to attract and lock the locking protrusion 204, thus unlocking the battery. The lifting support frame 3 then falls naturally under gravity, allowing the battery support frame 4 and the sealing spacer housing 5 to detach from the bearing sealing chamber 101 of the battery support frame 1. This allows the sealing spacer housing 5 to fully contact the outside air for better heat dissipation. Simultaneously, the side pressure relief pipe 601 and the pneumatic ejector sleeve 6 are slidably connected, their dimensions matching. The horizontal position of the pneumatic ejector sleeve 6... The centerline and the horizontal centerline of the horizontal guide groove 305 are parallel to each other. Therefore, if the battery temperature continues to rise and a deflagration occurs, the high-pressure gas inside can be discharged from the sealed spacer housing 5 through the side pressure relief pipe 601, and then discharged into the pneumatic ejection sleeve 6 through the pressure relief vent 605. As a result, the high-pressure gas will cause the internal pressure of the pneumatic ejection sleeve 6 to rise instantaneously, so as to push the side pressure relief pipe 601 and the rear side of the sealed spacer housing 5 to move, thereby ejecting the sealed spacer housing 5 as a whole backward and separating it from the car body. This avoids the damage to the car caused by the continued burning and explosion of the battery, and also avoids the threat to the safety of the occupants, which helps to improve the overall safety.

[0077] Please see Figures 1 to 9Optionally, the support frame carries the stored batteries through the battery storage compartment 501 inside the sealed spacer housing 5. Multiple spacer storage racks 502 are spaced apart within the battery storage compartment 501, each capable of storing a specific battery. Vertical spacer heat-conducting plates 504 are arranged between the spacer storage racks 502, with connecting heat pipes 505 positioned in the middle of the spacer heat-conducting plates 504. A contact top plate 506 is located at the top of the sealed spacer housing 5, and the spacer heat-conducting plates 504 are interconnected with the contact top plate 506 via the connecting heat pipes 505. The spacer heat-conducting plate 504 can conduct heat to the batteries in the spacer storage rack 502. The heat generated by the batteries is absorbed by the spacer heat-conducting plate 504 and then conducted to the contact top plate 506 through the connecting heat pipe 505. A cooling attachment plate 7 is provided on the top of the bearing sealing chamber 101. Multiple fitting protrusions 701 are evenly arranged in the middle of the cooling attachment plate 7. Multiple fitting grooves 507 are evenly arranged in the middle of the contact top plate 506. The top surface of the contact top plate 506 and the bottom surface of the cooling attachment plate 7 are attached to each other, and the fitting grooves are in contact with each other. The dimensions of the contact top plate 507 and the fitting protrusion 701 are matched, so when the sealing spacer housing 5 is raised and embedded into the bearing sealing chamber 101, the contact top plate 506 can be in contact with the cooling attachment plate 7 to transfer heat from the contact top plate 506 to the cooling attachment plate 7. The fitting groove 507 and the fitting protrusion 701 can increase the contact area to improve the heat conduction efficiency. The top of the cooling attachment plate 7 is uniformly and parallelly provided with multiple heat dissipation fins 702, and a cooling air duct 703 is horizontally arranged above the cooling attachment plate 7. The front end of the cooling air duct 703 is provided with... The device has an air inlet 704 and an exhaust 705 at the rear end of the cooling duct 703. The outer surface of the heat dissipation fins 702 is parallel to the horizontal center line of the cooling duct 703. Thus, the air inlet 704 and the exhaust 705 can be connected to the vehicle's air intake and exhaust structure, allowing air to flow through the cooling duct 703 when the vehicle is in motion. This allows the heat dissipation fins 702 to cool the cooling plate 7, thereby completing the heat dissipation work for the battery. The separate heat conduction and heat dissipation structure also facilitates the installation and removal of the battery, making it more convenient to use.

[0078] In use, the support frame must first be placed on the chassis of the corresponding vehicle, and the corresponding pipelines connected. The battery can then be installed in the spacer storage rack 502 of the battery storage compartment 501. When the battery needs to be replaced, the unlocking electromagnet 205 of the locking sleeve 202 at the top of the vertical guide groove 201 is energized to attract the corresponding locking protrusion 204 to move backward, causing the locking protrusion 204 to disengage from the locking slot 303 of the vertical slider 301, thereby unlocking the entire lifting support frame 3. Then, the entire lifting support frame 3 can move downward along the vertical guide groove 201 until the spacer base plate 401 is supported by the supporting roller 402. At this time, the locking protrusion 204 of the locking sleeve 202 at the bottom of the vertical guide groove 201 is unlocked. The locking slot 303, embedded in the vertical slider 301, locks the entire lifting support frame 3, thereby allowing the battery support frame 4 and its sealing spacer housing 5 to detach completely from the bearing sealing chamber 101 and descend. At this point, the battery support frame 4 and its sealing spacer housing 5 can be slid rearward along the horizontal guide groove 305 to remove them from the lifting support frame 3, completing the battery disassembly. Then, the sealing spacer housing 5 containing the new battery and the battery support frame 4 can be placed behind the lifting support frame 3 and slid forward so that the horizontal guide slider 403 engages with the horizontal guide groove 305, loading the battery support frame 4 and its sealing spacer housing 5 onto the lifting support frame. On the frame 3, the unlocking electromagnet 205 of the locking sleeve 202 at the bottom of the vertical guide groove 201 can then be energized to attract the corresponding locking protrusion 204 to move backward, causing the locking protrusion 204 to disengage from the locking slot 303 of the vertical slider 301, thereby unlocking the entire lifting support frame 3. Then, the entire lifting support frame 3 can be moved upward along the vertical guide groove 201, so that the battery support frame 4 and the sealing spacer housing 5 on it are fully embedded in the bearing sealing chamber 101 of the battery support frame 1. At the same time, the bottom opening 102 is closed by the spacer bottom plate 401. At this time, the locking protrusion 204 of the locking sleeve 202 at the top of the vertical guide groove 201 is embedded in the locking slot 303 of the vertical slider 301, thus unlocking the lifting support frame 3. Once the entire assembly is locked, the battery replacement is complete. When the battery temperature becomes abnormal, the unlocking electromagnet 205 of the locking sleeve 202 at the top of the vertical guide groove 201 will be energized, attracting the corresponding locking protrusion 204 to move rearward. This causes the locking protrusion 204 to disengage from the locking slot 303 of the vertical slider 301, unlocking the entire lifting support frame 3. The lifting support frame 3 can then move downwards along the vertical guide groove 201 until the spacer base plate 401 is supported by the supporting rollers 402. At this point, the battery support frame 4 and the sealing spacer housing 5 above it will completely detach from the bearing sealing chamber 101 and descend. If the battery temperature continues to rise and a deflagration occurs, the high-pressure gas inside will be discharged from the sealing spacer housing 5 through the side pressure relief pipe 601.The gas is then discharged through the pressure relief vent 605 into the pneumatic ejection sleeve 6. This high-pressure gas causes a sudden increase in pressure inside the pneumatic ejection sleeve 6, pushing the side pressure relief pipe 601 and the rear of the sealing spacer housing 5 to move. This ejects the sealing spacer housing 5 backward, separating it from the vehicle body and preventing further damage to the vehicle and threats to the safety of the occupants from continued battery combustion and explosion.

[0079] This invention discloses a power battery assembly for new energy vehicles. A vertically arranged guide frame 2 and a horizontal guide frame 304 serve as sliding guide structures in the vertical and horizontal directions, respectively. The sealed spacer housing 5 on the battery support frame 4 can hold the battery. The battery support frame 4 as a whole can move up and down and horizontally along the corresponding sliding guide structures in the vertical and horizontal directions, allowing it to be fitted into the bearing sealed chamber 101 of the battery support frame 1, or to be slidably removed. This facilitates the overall handling of the battery support frame 4 carrying the battery. The sealing spacer housing 5 is designed for quick installation and removal. A side pressure relief pipe 601 is located at the front end of the sealing spacer housing 5. This side pressure relief pipe 601 is slidably nested within the pneumatic ejection sleeve 6 fixed to the lifting support frame 3. When the battery inside the sealing spacer housing 5 explodes, the resulting high-pressure gas can be discharged through the side pressure relief pipe 601 to release pressure and prevent an explosion. Simultaneously, the high-pressure gas can be used to quickly eject the entire sealing spacer housing 5 horizontally, rapidly separating it from the vehicle body. This prevents damage to the entire vehicle body and avoids threats to the safety of the occupants, resulting in higher overall safety.

[0080] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
