[0020] See attached Figure 1-12 The present invention provides a battery swap station, including a battery compartment 100, having a plurality of battery storage compartments for storing and charging batteries; an explosion-proof compartment 110, which is arranged on the inner side of the compartment wall vertically facing the battery compartment 100 and is provided with a battery outlet 111 communicated with the explosion-proof compartment 110 on the compartment wall; a battery swap device, which is used to take out the battery in the battery compartment 100 and install it on a vehicle, take out the battery on the vehicle and push it into the battery compartment 100, and push the thermal runaway battery into the explosion-proof compartment 110; a flipping device, which is arranged in the explosion-proof compartment 110 and is driven by the thermal runaway battery, and is used to discharge the thermal runaway battery from the battery outlet 111.

[0021] Among them, the battery entrance and exit of the battery compartment 100 and the battery entrance of the explosion-proof compartment 110 are located on the same side, so that when a thermal runaway battery is found, the battery replacement equipment can move the thermal runaway battery out of the battery compartment 100 and push it into the explosion-proof compartment 110.

[0022] The battery exchange equipment is located on one side of the battery entrance and exit of the battery compartment 100. A battery exchange channel B is provided on one side of the battery compartment 100. A front wheel centering device C and a rear wheel centering device D are provided in the battery exchange channel B to position the new energy commercial vehicle A, so that the battery exchange equipment can perform battery exchange operations on the commercial vehicle.

[0023] Embodiment 1: See attached Figure 3 and 5 In this embodiment, the flipping device includes a flip frame 200 whose bottom is hinged to the bottom of the explosion-proof compartment 110 and rotates toward the battery outlet 111 under the action of gravity when in a free state, and a limiting component that is driven by the thermal runaway battery moving into the explosion-proof compartment 110 to release the horizontal limit of the flip frame 200 and put the flip frame 200 in a free state.

[0024] A hinge seat is provided at the bottom of the explosion-proof chamber 110, and the flip frame 200 is connected to the hinge seat through a hinge shaft. The center of gravity of the flip frame 200 is located between the hinge seat and the battery outlet 111 so that the flip frame 200 can rotate toward the battery outlet 111 under the action of gravity after the limit is released.

[0025] The above-mentioned turning frame limit assembly includes one or more limit plates 201 arranged along the length direction of the turning frame 200, a slide bar 202, a limit sleeve 203 fixed on the inner side wall of the explosion-proof chamber 110 and limiting the slide bar 202, and a contact plate 204 connected to the slide bar 202 and in contact with the thermal runaway battery and moving with the thermal runaway battery. The turning frame 200 is provided with an avoidance groove 200-1 matched with the limit plate 201. Since multiple limit plates 203 are provided, multiple slide bars 202 are also provided, and the two ends of the slide bar 202 are respectively connected to two adjacent limit plates 201 or respectively connected to the limit plate 201 and the contact plate 204.

[0026] At least two groups of slide bars 202 and limit sleeves 203 are arranged along the height direction of the limit plate 201 to ensure the stable connection of the limit plate 201, and the contact plate 204 is connected to the corresponding slide bars 202 in the height direction. When the battery contacts the contact plate 204 and drives the contact plate 204 to move together into the warehouse, the limit plate 201 is driven to move synchronously by the slide bar 202. When the thermal runaway battery moves into the explosion-proof warehouse 110, the limit plate 201 enters the avoidance groove 200-1 or is located outside the flip frame 200, thereby releasing the limit on the flip frame 200. Under the action of gravity, the flip frame 200 rotates toward the battery outlet 111. The thermal runaway battery on the top surface of the flip frame 200 slides down and is discharged from the explosion-proof warehouse 110 through the battery outlet 111 and enters the fire box 118. The control of the flip frame 200 adopts a mechanical structure and is driven by the thermal runaway battery. Such a design has high safety and reliability.

[0027] Embodiment 2: See attached Figure 3-5In this embodiment, in order to facilitate the thermal runaway battery to slide quickly from the flip frame 200 to the battery outlet 111. A smooth bar 205 is provided on the top surface of the flip frame 200, and a slide 206 for carrying the thermal runaway battery and limited on the smooth bar 205 is provided above the smooth bar 205. By designing the smooth bar 205, the resistance of the slide 206 and the battery in the process of moving to the battery outlet 111 can be reduced. There are multiple groups of smooth bars 205 along the length direction of the flip frame 200, and the bottom of the slide 206 is equipped with multiple limiting grooves 206-1. Both sides of the smooth bar 205 are located in the limiting groove 206-1 to limit the slide 206, and the pulley thereon supports the slide 206 to ensure that the battery will not cause the slide 206 to move with it when moving onto the slide 206 and will not limit the movement of the slide 206 to the battery outlet 111 after the flip frame 16 is flipped. The process of the thermal runaway battery entering the explosion-proof chamber 110 is the process of entering the slide 206. The smooth bar 205 forms a rolling fit with the rollers on the smooth bar 205 during the flipping of the flip frame 200, so that the slide 206 and the thermal runaway battery thereon quickly slide toward the battery outlet 111, and are discharged from the battery outlet 111 and enter the fire box 118.

[0028] Embodiment 3: See attached Figure 5 In this embodiment, a buffer block 207 cooperating with the flip frame 200 is provided at the bottom of the explosion-proof warehouse 110 to play a buffering and limiting role when one side of the flip frame 200 rotates to the bottom of the warehouse.

[0029] Embodiment 4: See attached Figure 1-6 In this embodiment, a door 112 is provided at the battery outlet 111 to close the battery outlet 111 when there is no thermal runaway battery, making the entire battery compartment 100 beautiful. The bottom of the door 112 is hinged to the explosion-proof compartment 110 through a hinge, and a door limit assembly is provided on the explosion-proof compartment 110 to limit the top of the door 112 and driven by the thermal runaway battery.

[0030] The door limiting assembly includes a lock tongue 114 that cooperates with the lock buckle 113 on the door 112, and a push plate 115 that moves along the length direction of the explosion-proof compartment 110 after contacting the thermal runaway battery that enters the flip frame 200 through the battery entrance of the explosion-proof compartment 110 to make the lock tongue 114 leave the lock buckle 113. The push plate 115 is connected to the lock tongue 114 and is slidably limited on the explosion-proof compartment 110.

[0031] There are multiple groups of lock buckles 113 and matching lock tongues 114 along the length direction of the door 112, and all lock tongues 114 are connected to a connecting rod 120 limited on the explosion-proof compartment 110. One end of the connecting rod 120 extends to a position close to the battery entrance, so that when the door 112 is reset, the connecting rod 120 is pulled to move the lock tongue 114 and re-limit it.

[0032] In order to make the locking tongue 114 move horizontally stably, a limiting plate 121 having a guide limiting groove 121-1 is provided on the explosion-proof chamber 110. The locking tongue 114 is located outside the limiting plate 121 and is connected to a connecting rod 120 located inside the limiting plate 121 by means of a guide pin 122 passing through the guide limiting groove 121-1.

[0033] In order to make the push plate 115 move stably, a guide rod 123 and a sliding bracket 124 slidably limited on the guide rod 123 are provided in the explosion-proof warehouse 110. The push plate 115 is fixed on the sliding bracket 124, and the connecting rod 120 is connected to the sliding bracket 124.

[0034] In this embodiment, the limit and release of the door 112 adopt a mechanical structure. When the battery exchange equipment pushes the thermal runaway battery into the warehouse through the battery entrance 111, the battery will contact the push plate 115 after moving a certain distance and push the push plate 115 to move into place with the battery. In this process, the lock tongue 114 moves horizontally and leaves the lock buckle 113, thereby releasing the limit of the door 112.

[0035] The thermal runaway battery drives the door limit assembly and the flip device synchronously or first drives to release the limit of the door 112 and then drives to release the limit of the flip frame 200. The door 112 is pushed open by the thermal runaway battery sliding toward the battery outlet 111 and then flipped outward to open the battery outlet. Then the thermal runaway battery slides from the battery outlet 111 into the fire fighting box 118 containing water.

[0036] Embodiment 5: See attached Figure 5 and 6 In this embodiment, a door opening assembly is further provided between the push plate 115 and the explosion-proof chamber 110, and the door opening assembly includes a driving rod 116 hinged to the push plate 115 and an outer push rod 117 hinged to the driving rod 116 and the explosion-proof chamber 110 respectively. The outer push rod 117 rotates outward with the driving force of the push plate 115 to move the free end outward and push the chamber door 112 which has been released from the limit outward. After the chamber door 112 is opened outward, a passage is formed inside the chamber door 112 for the thermal runaway battery to move downward to the fire fighting box 118 through the inside of the chamber door 112. A push plate 125 is provided on the chamber door 112 to contact the outer end of the outer push rod 117.

[0037] A slide frame 119 is provided on one side of the fire extinguishing box 118, and the free end of the door 112 is overlapped on the slide frame 119 after it is opened. Fluent strips are provided on the inner side of the door 112 and the slide frame 119 to facilitate the battery to enter the fire extinguishing box 12 through the door 112 and the slide frame 119.

[0038] After the thermal runaway battery is removed from the explosion-proof compartment 110, the compartment door limit assembly and the flip device are manually reset.

[0039] Embodiment 6: See attached Figure 1 and 2 , 7 and 8, in this embodiment, the battery swapping equipment includes a battery swapping device and a displacement device for driving the battery swapping device to move between the battery swapping position of the vehicle and the battery compartment 100. The battery swapping device includes a battery swapping bracket 300 provided with a temporary battery storage position and a battery push-pull assembly 301 provided on the battery swapping bracket 300 and provided for each temporary battery storage position, and the battery swapping bracket 300 is connected to the execution end of the displacement device.

[0040] The battery exchange bracket 300 is provided with two temporary battery storage positions, and each temporary battery storage position is equipped with a battery push-pull assembly 301. When exchanging batteries, one temporary battery storage position is used to store fully charged batteries, and the other is empty to store low-power batteries.

[0041] The execution end of the displacement device is connected to the battery swap bracket 300 and the battery swap bracket 300 is suspended. The displacement device includes two hanging rails 302 arranged in parallel, a hanging rail mounting frame 303 arranged between the hanging rails 302 and the ground, a translation bracket 304 limited on the two hanging rails 302, and a translation drive assembly driving the translation bracket 304 to move along the hanging rails 302. The battery swap bracket 300 is connected to the translation bracket 304. The translation drive assembly includes a translation drive motor 307 fixed on the translation bracket 304, a gear 305 fixed on the driving end of the translation drive motor 307, and a rack 306 fixed on the hanging rail 302 and meshed with the gear 305. A slide rail is provided on the hanging rail 302, and a slider matching the slide rail is provided on the translation bracket 304 to achieve stable movement of the translation bracket 304.

[0042] By suspending the battery swap bracket 300, damage to the battery swap channel caused by the conventional rail-type walking structure and deformation of the rail-type walking structure after long-term use can be avoided, which also facilitates the passage of vehicles and the layout and installation of various devices.

[0043] Embodiment 7: See attached Figure 7-10 , which is different from the sixth embodiment, in this embodiment, a position adjustment device is provided between the translation bracket 304 and the battery exchange bracket 300, and the position adjustment device includes two sets of position adjustment components symmetrically arranged on both sides of the width direction of the battery exchange bracket 300, and each set of position adjustment components includes a first lifting drive component and a second lifting drive component sequentially arranged along the length direction of one side of the battery exchange bracket 300 and both execution ends are movably connected to the battery exchange bracket 300. Among them, the first lifting drive component is close to the battery entrance and exit of the battery compartment 100, and the second lifting drive component is far away from the battery entrance and exit of the battery compartment 100.

[0044] A first movable connection component is provided between the execution end of the first lifting drive component and the battery swap bracket 300, and a second movable connection component is provided between the execution end of the second lifting drive component and the battery swap bracket 300.

[0045] The first connecting assembly includes a first fixed seat 308 hinged on the battery exchange bracket 300, a second fixed seat 309 fixed to the execution end of the first lifting drive component, and a connecting rod 310 hinged to the first fixed seat 308 and the second fixed seat 309 respectively.

[0046] The second connecting assembly includes a first connecting seat 311 hinged to the battery exchange bracket 300, a second connecting seat 312 fixed to the execution end of the second lifting drive component, a first articulated seat 313 hinged to the first connecting seat 311, and a second articulated seat 314 whose two ends are respectively hinged to the first articulated seat 313 and the second connecting seat 312.

[0047] In the two connection components of this embodiment, the first fixed seat 308 and the first connection seat 311, the second fixed seat 309 and the second connection seat 312 have the same structure, and the difference lies in the connection method formed by the connecting rod 310, the first hinge seat 313 and the second hinge seat 314. Such a design not only allows the battery swap bracket 300 to be lifted and lowered and swung left and right, and pitched forward and backward within a preset angle range under the drive of the lifting drive component, so that the temporary storage position of the battery on the battery swap bracket 300 is aligned with the commercial vehicle or the battery storage bin; it also reduces the relative position movement between the battery swap bracket 300 and the lifting drive component when the battery enters the battery swap bracket 300, so that the process of the battery entering and exiting the battery swap bracket 300 is stable.

[0048] The first lifting drive component and the second lifting drive component mentioned above both include a rigid chain, a chain storage box 322 for storing the rigid chain, and a driving gear and a matching gear drive motor 323 arranged on the chain storage box 322 and driving the rigid chain to move. The battery exchange bracket 300 is located below the driving end of the rigid chain and is movably connected to the driving end. The rigid chain drive is adopted, and the strong bearing capacity of the rigid chain is utilized. The chain storage box 322 of the rigid chain can also be used as a column of the entire adjustment device, reducing the number of components. The lifting drive component mentioned above can also adopt a gear rack structure, electric cylinder, chain, etc. driven by a motor to realize linear drive. The tops of all chain storage boxes 322 are connected to the translation bracket 304.

[0050] The limiting cavity of the first limiting block 315 and the limiting cavity of the second limiting block 316 are both provided with a cushion block 326 matched with the first spherical crown movable block 318 or the second spherical crown movable block 320, and the cushion block 326 is limited in the cavity by a retaining ring through the hole.

[0051] In this embodiment, the battery swap bracket 300 and the two limit rods 317 in each position adjustment assembly and the lifting drive components form a four-bar structure, and the connection is in a ball-jointed structure that can rotate within a certain range. The battery swap bracket 300 can be lifted and lowered within a height range and swung left and right, and pitched forward and backward within a preset angle range by driving the four lifting drive components, so that the temporary storage position of the battery on the battery swap bracket 300 is aligned with the commercial vehicle or battery storage compartment.

[0052] Taking Example 8 as an example, the battery replacement process of the battery replacement station of the present invention is as follows.

[0053] In the initial state, the battery replacement device is located on one side of the battery entrance and exit of the battery compartment 100 to facilitate the new energy commercial vehicle A to be replaced with a battery to enter the battery replacement channel B and stop at the battery replacement position.

[0054] One of the battery temporary storage locations of the battery swap device stores a fully charged battery, while the other has no battery. When the commercial vehicle drives to the designated area in the channel, the front wheel centering device C and the rear wheel centering device D will push and tighten the front and rear wheels of the vehicle to automatically fix the commercial vehicle in the battery swap position required by the battery swap device for subsequent battery swapping.

[0055] While the front wheel centering device C and the rear wheel centering device D push and fix the commercial vehicle, the displacement device drives the battery exchange device to move to the rear of the new energy commercial vehicle A, and automatically scans the rear of the commercial vehicle after the commercial vehicle is fixed, calculates and adjusts the upper and lower heights and the left and right front and rear angles of the battery exchange device through the displacement device and the position adjustment device so that the battery temporary storage position without a battery is flush with the bottom of the battery compartment of the commercial vehicle, and the matching battery push-pull component 301 pulls the low-charged battery in the commercial vehicle into the current battery temporary storage position; then, by adjusting the height of the battery exchange device upward or downward so that the fully charged battery is aligned with the battery compartment of the commercial vehicle, the matching battery push-pull component 301 pushes the fully charged battery into the battery compartment of the commercial vehicle, thereby completing the battery exchange.

[0056] After the battery swap is completed, the front wheel centering device C and the rear wheel centering device D that receive the signal release the limit on the vehicle, and the vehicle can drive out of the channel. The displacement device and the position adjustment device drive the battery temporary storage position with the low-power battery in the battery swap device to move to the side of the battery storage compartment without a battery in the battery compartment 100, and the matching battery push-pull component 301 pushes the low-power battery into the battery storage compartment to charge it. At this time, all the battery temporary storage positions in the battery swap device have no batteries; then, the displacement device and the position adjustment device drive any battery temporary storage position in the battery swap device to move to the battery compartment entrance and exit side with a fully charged battery in the battery compartment 100, and the matching battery push-pull component 301 pulls the fully charged battery into the battery temporary storage position to prepare for the next battery swap.

[0057] During the battery swapping process, the battery of new energy commercial vehicle A is pulled out or pushed in, causing the change in the weight of new energy commercial vehicle A, causing the vehicle body to rise or fall. The position adjustment device can adjust the height and / or angle of the battery swapping bracket 300 to ensure smooth battery swapping.

[0058] The battery emergency handling process of the battery swap station of the present invention is as follows: when thermal runaway of the battery is detected, the displacement device and the position adjustment device drive the battery swap device to move quickly to one side of the thermal runaway battery, and then the battery push-pull assembly 301 pulls the thermal runaway battery out of the battery compartment 100 and pulls it into the empty battery temporary storage position; the displacement device and the position adjustment device drive the battery swap device to move quickly to the battery entrance side of the explosion-proof compartment 110, and then the battery push-pull assembly 301 pushes the thermal runaway battery into the explosion-proof compartment 110. After the thermal runaway battery moves a certain distance into the warehouse, it will push the push plate 115 and the contact plate 204 to move inward synchronously and into place. In this process, the limit on the warehouse door 112 will be released and the top of the warehouse door 112 will be pushed outward by the outer push rod 117 to quickly open the battery outlet 111 and then rest on the sliding frame 119, and the limit on the flip frame 200 will be released to flip it toward the battery outlet 111. The thermal runaway battery and the slide frame 206 below it will quickly move toward the battery outlet 111 and finally fall into the fire extinguishing box 118.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
