DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] like Figures 1 to 4As shown, an electric vehicle battery exchange cabinet described in an embodiment of the present invention includes a plurality of cabinets 1, which are fitted in sequence, and a lifting assembly is provided on the top of each cabinet 1. The lifting assembly includes a positioning seat 2 and a driving motor 4 located above the cabinet 1. There are two positioning seats 2 and they are fixedly connected to the cabinet 1. A retractable roller 3 is rotatably installed on the inner wall of the positioning seat 2. The output end of the driving motor 4 is fixedly connected to one end of one of the retractable rollers 3. Gears 5 are fixedly installed on the outer walls of the two retractable rollers 3. The teeth of the two gears 5 are meshed, and a connecting belt is wrapped around the outer wall of the retractable roller 3. 6, a lifting block 7 is fixedly installed at one end of the connecting belt 6 away from the retracting roller 3, and a track groove is symmetrically provided on the inner wall of the cabinet 1. The outer wall of the lifting block 7 is slidably connected to the inner wall of the track groove. A placement component is arranged between the two lifting blocks 7, and a plurality of charging compartments are arranged on the front of the cabinet 1. A moving component and a charging component are arranged on the inner side of the charging compartment. When the battery is replaced and the battery is placed, the charging compartment in an idle state will be opened under the action of the moving component, and the battery to be charged will be placed above the placement component of the corresponding cabinet 1, and then the corresponding driving motor 4 will be started, and the driving motor 4 will be driven The retractable roller 3 connected to it is driven to rotate. When the retractable roller 3 rotates, the gear 5 causes the corresponding other retractable roller 3 to rotate synchronously in the opposite direction. The two retractable rollers 3 rotate synchronously to reel up the connecting belt 6. After the connecting belt 6 is reeled up, it drives the placement component to rise through the lifting block 7, thereby driving the battery to rise. When the battery rises to the inner side of the moving component, the moving component pushes the battery into the charging bin and charges it through the charging component. When taking out the battery, the placement component is moved to the corresponding charging bin under the action of the driving motor 4, and then the moving component is driven to move the battery to the charging bin. Pull out the fully charged battery, and the battery will move to the top of the placement component after being pulled out. Then, the placement component will be lowered to the lowest point again under the action of the driving motor 4. At this time, the battery on the placement component can be removed. In summary, when charging, place the battery on the placement component at the bottom, and the battery can be automatically transported to the charging bin for charging. When taking the battery, the device will take out the charged battery and move it to the bottom. The user can directly carry the battery away without lifting the battery and placing it in the charging bin or taking it out of the charging bin, which greatly improves the convenience of the user.

[0036] like Figures 1 to 4As shown, a guide seat 8 is symmetrically fixedly installed on the top of the cabinet 1, and a guide roller 9 is rotatably installed on the inner wall of the guide seat 8. The connecting belt 6 is overlapped on the outer wall of the guide roller 9, and a motor seat 10 is fixedly installed on the top of the cabinet 1, and the driving motor 4 is fixedly installed on the inner wall of the motor seat 10; the position of the guide roller 9 is fixed by the guide seat 8, and the movement trajectory of the connecting belt 6 is controlled under the action of the guide roller 9, so that the connecting belt 6 drives the lifting block 7 to move in the vertical direction, and the gravity exerted on the connecting belt 6 is downward in a straight line. This vertical pulling force helps to reduce shaking and deviation during the lifting process, thereby improving the stability of the entire lifting system, and the driving motor 4 is fixed by the motor seat 10 to provide a fulcrum for the driving motor 4, so that the driving motor 4 can provide stable power for the operation of the device.

[0037] like Figures 1 to 6 As shown, the moving component includes two automatic telescopic rods 11, one end of the automatic telescopic rod 11 is fixedly connected to the inner wall of the charging bin, the other end of the automatic telescopic rod 11 is fixedly installed with a side panel 12, a front panel 13 is fixedly installed between the two side panels 12, a cross panel 14 is fixedly installed on the outer wall of the front panel 13 close to the side panel 12, a push plate 15 is fixedly installed on the side of the cross panel 14 away from the front panel 13, and a hook plate 16 is fixedly installed on the bottom of the cross panel 14, a battery body 21 is arranged on the top of one of the placement components, and a handle 22 is fixedly installed on the outer wall of the battery body 21; when the battery body 21 is placed, the automatic telescopic rod 11 in the charging bin in an idle state will extend, push the side panel 12 and the front panel 13 to move outward, and then the placement component drives the battery body 21 to move upward, so that the battery body 21 moves to the side panel 12 and The front plate 13 is moved between the side plates 12 and the front plate 13, and then the automatic telescopic rod 11 is retracted. The front plate 13 drives the push plate 15 to move into the charging bin through the cross plate 14, and the push plate 15 pushes the battery body 21 into the charging bin for charging. When the placement component drives the battery body 21 to move up between the side plates 12 and the front plate 13, the hook plate 16 is inserted between the battery body 21 and the handle 22. When the battery body 21 is taken out, the placement component is first moved to the corresponding charging bin, and then the automatic telescopic rod 11 is extended to move the front plate 13 out. When the front plate 13 moves, the cross plate 14 drives the hook plate 16 to move, and the hook plate 16 pulls the battery body 21 out of the charging bin through the handle 22. The pulled out battery body 21 moves above the placement component, and finally the placement component drives the battery body 21 to descend, thereby achieving the placement and removal of the battery body 21.

[0038] like Figures 7 to 10As shown, the placement component includes a rotating seat 17 fixedly installed between the two lifting blocks 7, the inner wall of the rotating seat 17 is rotatably installed with a rotating shaft 18, the outer wall of the rotating shaft 18 is rotatably installed with a supporting plate 19, the outer wall of the supporting plate 19 overlaps the inner wall of the rotating seat 17, and the outer wall of the cabinet 1 and the lower part of the supporting plate 19 is fixedly installed with a supporting plate 20; when no user is performing battery replacement, the driving motor 4 will make the placement component descend to the lowest point, and in the process of the placement component descending, the rotating seat 17 will drive the supporting plate 19 to descend through the rotating shaft 18, When the support plate 19 descends, it will be squeezed by the anti-plate 20. The squeezed support plate 19 will flip upward around the rotating shaft 18, so that the support plate 19 is in a folded state. By folding the support plate 19, the space outside the device can be saved. At the same time, the support plate 19 can be protected to prevent the support plate 19 from being damaged by being kept in the unfolded state. When a user performs battery replacement, the support plate 19 is first separated from the anti-plate 20 under the action of the drive motor 4, and the support plate 19 is no longer restricted by the anti-plate 20 and is thus unfolded.

[0039] like Figure 8 and Fig.10 As shown, the inner wall of each support plate 19 is provided with a group of limit components, wherein one group of limit components is fitted with the outer wall of the battery body 21, and the limit components include a torsion spring shaft 23 and a positioning plate 24, the outer wall of the torsion spring shaft 23 is fixedly connected to the inner wall of the positioning plate 24, and the two ends of the torsion spring shaft 23 are fixedly connected to the inner wall of the support plate 19; the limit components arranged on the support plate 19 are used to position the battery body 21, so that the battery body 21 is fitted with multiple positioning plates 24 at the same time when the battery body 21 is placed, so as to position the battery body 21, and the positioning plate 24 can be flipped to the inner side of the support plate 19 through the action of the torsion spring shaft 23, and at the same time has the function of automatic reset, so as to prevent the positioning plate 24 from affecting the taking and placing of the battery body 21.

[0040] like Figure 1 to Figure 2 As shown, a counterweight block 25 is fixedly installed on the inner wall of the lifting block 7, and a limit slide block 26 is fixedly installed on the outer wall of the lifting block 7. A limit slide groove is provided on the inner wall of the cabinet 1, and the inner wall of the limit slide groove is slidably connected to the outer wall of the limit slide block 26. An elastic stop block 27 is symmetrically fixedly installed on the top of the support plate 19; the weight of the lifting block 7 is increased by the action of the counterweight block 25 to ensure that the lifting block 7 can fall stably even in the empty running state; the cooperation of the limit slide block 26 and the limit slide groove increases the stability of the lifting block 7 during lifting and lowering to prevent rollover; through the set elastic stop block 27, the elastic stop block 27 will collide with the cabinet 1 when the support plate 19 flips over, and the elasticity of the elastic stop block 27 buffers the impact force to prevent damage caused by the collision. At the same time, through the restriction of the elastic stop block 27, the flipping angle of the support plate 19 is less than ninety degrees, so it can be automatically unfolded after the support plate 19 moves up.

[0041] like Figure 1 to Figure 2 and Fig.11 As shown, the inner wall of the cabinet 1 is symmetrically slidably installed with a baffle 28, and the inner wall of the cabinet 1 is symmetrically fixed with two sets of slide columns 29, and the outer walls of the two sets of slide columns 29 are respectively slidably connected with the inner walls of the two baffles 28, and a set of elastic members 30 are fixedly installed between the outer walls of the two baffles 28 and the inner wall of the cabinet 1, and the elastic members 30 are respectively sleeved on the outer sides of the slide columns 29; when the power is replaced, the upward movement of the lifting block 7 will squeeze the baffle 28, and the baffle 28 will be moved away along the slide column 29 through the inclined surface at the bottom end of the baffle 28. The lifting block 7 is then moved horizontally in the direction away from the charging compartment. At this time, the track groove is in an open state, and the elastic member 30 is in a compressed state. When no one is performing battery replacement work, the lifting block 7 will drop to the lowest position. At this time, the lifting block 7 is separated from the baffle 28, and the baffle 28 is no longer restricted by the lifting block 7. The elastic member 30 will stretch and push the baffle 28 to move in the direction of the charging compartment. At this time, the baffle 28 will close the track groove, thereby preventing garbage and other debris from entering the track groove and affecting the normal use of the device when the device is idle.

[0042] like Figure 1 As shown, it also includes an outer frame 33, and several cabinets 1 are fixedly installed on the inner side of the outer frame 33, and a ceiling 34 is arranged above the outer frame 33; the multiple cabinets 1 are connected together by the outer frame 33, which can enhance the connection strength between the cabinets 1, thereby increasing the stability of the cabinets 1, and at the same time, the multiple cabinets 1 are supported by the outer frame 33, so that the contact area between the device and the ground is increased, and the overall anti-overturning ability is improved. By setting the ceiling 34, the device can be covered and protected to avoid damage to the device caused by the natural environment.

[0043] like Figure 1 As shown, vertical panels 35 are symmetrically fixedly installed on the top of the outer frame 33, the top of the vertical panels 35 is fixedly connected to the bottom of the ceiling 34, and the inner wall of the top of the ceiling 34 is fixedly installed with solar panels 36; the position of the ceiling 34 is fixed by the vertical panels 35, so that the ceiling 34 can protect the device, and the solar panels 36 are arranged on the top of the ceiling 34, which can have better lighting conditions and better absorb light energy. The solar panels 36 can convert light energy into electrical energy for use by the device, thereby saving energy.

[0044] like Figure 1 to Figure 2 and Fig.12As shown, the charging assembly includes a mounting plate 37 fixedly mounted on the inner wall of the charging bin and two side limit plates 39, a charging interface 38 is fixedly mounted on the outer wall of the mounting plate 37 and located between the two side limit plates 39, the two side limit plates 39 are respectively fixedly mounted on both sides of the mounting plate 37, and a top limit plate 40 is fixedly mounted on the top of the mounting plate 37; when the mobile assembly pushes the battery body 21 into the charging bin, the battery body 21 will be connected to the charging interface 38, thereby achieving the effect of charging the battery body 21, and the battery body 21 is guided and limited by the side limit plates 39 and the top limit plates 40 to prevent the battery body 21 from being offset, thereby ensuring that the battery body 21 can be effectively connected to the charging interface 38.

[0045] Working principle: When replacing the battery, when placing the battery, the idle charging compartment will be opened under the action of the mobile component, and the battery to be charged will be placed on the placement component of the corresponding cabinet 1, and then the corresponding drive motor 4 will start, and the drive motor 4 will drive the retracting roller 3 connected thereto to rotate. When the retracting roller 3 rotates, the gear 5 will cause the other corresponding retracting roller 3 to rotate synchronously in the opposite direction. The two retracting rollers 3 will rotate synchronously to reel up the connecting belt 6. After the connecting belt 6 is reeled up, it will drive the placement component to rise through the lifting block 7, thereby driving the battery to rise. When the battery rises to the inside of the mobile component, the mobile component will push the battery into the charging compartment and charge it through the charging component. When taking out the battery, the placement component is moved to the corresponding charging bin under the action of the driving motor 4, and then the fully charged battery is pulled out under the action of the moving component. After being pulled out, the battery will move above the placement component, and then the placement component will be lowered to the lowest point again under the action of the driving motor 4. At this time, the battery on the placement component can be removed. In summary, when charging, the battery is placed on the placement component at the bottom, and the battery can be automatically transported to the charging bin for charging. When taking the battery, the device will take out the charged battery and move it to the bottom. The user can directly carry the battery away without lifting the battery and placing it in the charging bin and taking it out of the charging bin, which greatly improves the convenience of the user.

[0046] The position of the guide roller 9 is fixed by the guide seat 8, and the movement trajectory of the connecting belt 6 is controlled under the action of the guide roller 9, so that the connecting belt 6 drives the lifting block 7 to move in the vertical direction. The gravity exerted on the connecting belt 6 is downward in a straight line. This vertical pulling force helps to reduce shaking and deviation during the lifting process, thereby improving the stability of the entire lifting system. The drive motor 4 is fixed by the motor seat 10 to provide a fulcrum for the drive motor 4 so that the drive motor 4 can provide stable power for the operation of the device. When the battery body 21 is placed, the automatic telescopic rod 11 in the idle charging compartment will extend, pushing the side panel 12 and the front panel 13 to move outward, and then the placement component drives the battery body 21 to move upward, so that the battery body 21 moves to between the side panel 12 and the front panel 13 The push plate 15 pushes the battery body 21 into the charging bin for charging. When the placement component drives the battery body 21 to move up between the side plate 12 and the front plate 13, the hook plate 16 is inserted between the battery body 21 and the handle 22. When the battery body 21 is taken out, the placement component is first moved to the corresponding charging bin, and then the automatic telescopic rod 11 is extended to move the front plate 13 out. When the front plate 13 moves, the hook plate 16 is driven to move through the cross plate 14. The hook plate 16 pulls the battery body 21 out of the charging bin through the handle 22, and the pulled out battery body 21 moves above the placement component. Finally, the placement component drives the battery body 21 to descend, thereby achieving the placement and removal of the battery body 21.

[0047] When there is no user performing battery replacement work, the driving motor 4 will lower the placement component to the lowest point. During the lowering process of the placement component, the rotating seat 17 will drive the support plate 19 to descend through the rotating shaft 18. When the support plate 19 descends, it will be squeezed by the abutment plate 20. The squeezed support plate 19 will flip upward around the rotating shaft 18, so that the support plate 19 is in a folded state. By folding the support plate 19, the space outside the device can be saved. At the same time, the support plate 19 can be protected to prevent the support plate 19 from being damaged by being kept in the unfolded state. When a user performs battery replacement work, the driving motor 4 will first make the support plate 19 leave the abutment plate 20, and the support plate 19 will no longer be abutted. The lifting block 7 is restricted by the baffle 20 and is thus unfolded. When the battery is replaced, the lifting block 7 moves upward to squeeze the baffle 28, and the baffle 28 is translated along the slide column 29 away from the charging bin through the inclined surface at the bottom end of the baffle 28. At this time, the track groove is in an open state, and the elastic member 30 is in a compressed state. When no one is performing the battery replacement work, the lifting block 7 will drop to the lowest position. At this time, the lifting block 7 is separated from the baffle 28, and the baffle 28 is no longer restricted by the lifting block 7. The elastic member 30 will stretch and push the baffle 28 to move toward the charging bin. At this time, the baffle 28 will close the track groove, thereby preventing garbage and other debris from entering the inside of the track groove and affecting the normal use of the device when the device is idle.
