Description
Technical Field
[0001] The utility model relates to the technical field of electric vehicle battery swapping, in particular to a synchronous battery access mechanism. Background Art
[0002] In order to achieve rapid energy replenishment for existing electric vehicles, some electric vehicles adopt the method of battery swapping. Through the battery swapping method, electric vehicles can achieve power replenishment in an extremely short time. The specific method is to remove the original depleted battery on the electric vehicle through a battery swapping device, and then replace the fully charged battery onto the electric vehicle through the battery swapping device. Replacing the new fully charged battery onto the electric vehicle in this way is the battery swapping method. In order to remove the depleted battery on the electric vehicle and store the new fully charged battery back onto the electric vehicle, a battery swapping device is required, and the battery swapping device needs to have a mechanism capable of accessing the battery.
[0003] In the prior art, in the technical solution of a Chinese patent document (publication number: CN210454438U, patent name: An Automatic Battery Conveyor for Electric Vehicles), it is disclosed that "it includes a battery swapping battery compartment body for automatically conveying batteries and a control system. The battery swapping battery compartment body is arranged on the vehicle chassis. The battery swapping battery compartment body includes a front compartment, a rear compartment and a rotating compartment that communicate with each other. The rotating compartment is arranged between the front compartment and the rear compartment. A battery compartment entrance is arranged at the front end of the front compartment; battery conveying devices are arranged at the bottoms of both the front compartment and the rear compartment, and a battery holding device, a battery rotating device and a battery transmission mechanism are arranged in the rotating compartment; the battery conveying device, the battery rotating device and the battery transmission mechanism are all connected to the control system, and the control system controls the battery to be sent from the front compartment into the rotating compartment and makes the battery rotate from a longitudinal state to a transverse state and enter the rear compartment."
[0004] Combined with the description content of the patent document and the attached drawings, the overall structure of this battery conveyor is relatively complex, which is likely to increase the overall production and processing difficulty. And during battery swapping, the battery enters the front compartment longitudinally from the battery compartment entrance and is conveyed through it into the rotating compartment. The rotating compartment drives the battery to move by friction wheels. During the movement, the battery is not clamped and conveyed, which is likely to cause the position of the battery to deviate during the conveying process, resulting in unstable and unsmooth battery storage. Summary of the Utility Model
[0005] The utility model overcomes the deficiencies in the prior art and provides a synchronous battery access mechanism, enabling the battery pack to always move in a straight line state, making the battery mechanism more stable.
[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] A synchronous access battery mechanism includes a frame and a battery pack access driving mechanism. Bottom plates are provided at both ends of the frame. Driving translation components are clamped at both ends of the battery pack access driving mechanism, and the driving translation components are slidably connected to the sides of the bottom plates. An unlocking component corresponding to a locking component is further provided on the side of the bottom plate. The unlocking component includes a toggle piece connected to the frame, and the toggle piece extends in the vertical direction. The locking component includes a locking block and a locking bracket. The locking block is provided with a locking slot. The connecting column of the battery pack is installed in the locking slot. One end of the locking piece is rotatably connected to the locking block, the other end is rotatably connected to the locking bracket, and the middle part is embedded in the locking slot to block the connecting column. When the clamping block of the battery pack clamps the driving translation component, the toggle piece pushes the locking bracket to move, driving the middle part of the locking piece to disengage from the locking slot to release the locking, so that the battery pack can slide laterally relative to the bottom plate along with the driving translation component and disengage from the locking slot.
[0008] Furthermore, the unlocking component includes a first telescopic member and a mounting bracket. The middle part of the toggle piece is hinged to the mounting bracket. The first telescopic member abuts against the middle part of the toggle piece. One end of the toggle piece is hinged to a second telescopic member, and the other end of the toggle piece corresponds to the locking bracket of the locking component.
[0009] Furthermore, the toggle piece is arc-shaped, and the locking bracket is pushed to move through the arc-shaped edge of the toggle piece.
[0010] Furthermore, the battery pack access driving mechanism includes a cylinder. The cylinder rod of the cylinder is connected with a connecting piece. The connecting piece is connected with a push plate. First sliders are arranged below both ends of the push plate. The first sliders are slidably connected with a first linear guide rail, and the first linear guide rail is fixed on the inner side surface of the bottom plate.
[0011] Furthermore, the driving translation component includes a plurality of first translation members and second translation members. Upper clamping openings are arranged at the upper ends of the first translation members and the second translation members. The clamping block of the battery pack is clamped by being embedded in the upper clamping openings, and inclined surfaces are arranged at the upper ends of the upper clamping openings.
[0012] Furthermore, second sliders are arranged on the sides of the first translation members and the second translation members. The second sliders are slidably connected with a second linear guide rail, and the second linear guide rail is fixed on the outer side surface of the bottom plate.
[0013] Furthermore, a lower clamping opening is arranged at the lower end of the first translation member. Positioning openings are arranged at both ends of the push plate, and the positioning openings and the lower clamping opening are used in cooperation with each other.
[0014] Furthermore, a conveying chain is arranged around the bottom plate, and a notch is arranged on the outer end surface of the bottom plate. The conveying chain is clamped in the notch.
[0015] Furthermore, a first sensor detection assembly is arranged on the outer side of the middle part of the base plate, a mounting frame is arranged on the side of the first sensor detection assembly, a second sensor detection assembly is arranged on the inner side of one end of the base plate, and a third sensor detection assembly is arranged on the outer side of the other end of the base plate.
[0016] Furthermore, the first telescopic member is a power telescopic mechanism, the second telescopic member is an elastic telescopic structure, the second telescopic member is connected to a moving block, one end of the moving block is hinged to the toggle plate, and one end of the moving block is clamped on the conveying chain.
[0017] Compared with the prior art, the beneficial effects of the utility model are:
[0018] When the locking block is lifted to unlock the connecting column, the battery pack can be stored and retrieved by sliding the driving translation assembly horizontally relative to the base plate, thereby optimizing the overall structural complexity of the battery mechanism and reducing the overall production and processing difficulty of the battery mechanism. By driving the translation assembly to move the battery pack, the battery pack can always move in a straight line, making the battery mechanism more stable and preventing the battery pack from tilting during movement, which would result in less smoothness and stability during battery replacement.

DETAILED DESCRIPTION
[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0029] like Figures 1 to 2 As shown, a synchronous battery access mechanism includes a frame 11 and a battery pack access drive mechanism 2, a bottom plate 1 is provided at both ends of the frame 11, and a driving translation assembly 3 is clamped at both ends of the battery pack access drive mechanism 2, and the driving translation assembly 3 is slidably connected to the side of the bottom plate 1; the side of the bottom plate 1 is also provided with an unlocking assembly corresponding to the locking assembly, and the unlocking assembly includes a toggle piece 13 connected to the frame 11, and the toggle piece 13 extends in the vertical direction; the locking assembly includes a locking block 9 and a locking frame 15, and the locking block 9 is provided with a locking slot 901; the connecting column 802 of the battery pack 8 is installed in the locking slot 901, and one end of the locking piece 10 is rotatably connected to the locking block 9, and the other end is rotatably connected to the locking frame 15 , and the middle part is embedded in the locking groove 901 to stop the connecting column 802; when the clamping block 801 of the battery pack 8 is clamped with the driving translation component 3, the toggle plate 13 pushes the locking frame 15 to move and drives the middle part of the locking plate 10 to disengage from the locking groove 901 and release the lock, so that the battery pack 8 can slide laterally relative to the bottom plate 1 with the driving translation component 3 and disengage from the locking groove 901, thereby optimizing the overall structural complexity of the battery mechanism and reducing the overall production and processing difficulty of the battery mechanism. By driving the translation component 3 to move the battery pack 8, the battery pack 8 is kept in a straight line at all times to move, making the battery mechanism more stable and preventing the battery pack 8 from tilting during movement, which results in insufficient smoothness and stability during battery replacement.
[0030] Specifically, Figure 3As shown in the figure, the battery pack access driving mechanism 2 includes a cylinder 201. The cylinder rod of the cylinder 201 is connected with a connecting piece 202. The connecting piece 202 is connected with a push plate 203. Below both ends of the push plate 203, there are first sliders 204. The first sliders 204 are slidably connected with a first linear guide 205. The first linear guide 205 is fixed on the inner side surface of the bottom plate 1. The telescopic movement of the cylinder rod of the cylinder 201 will drive the connecting piece 202 to perform a linear motion, and the connecting piece 202 will drive the push plate 203 to perform a linear motion on the first linear guide 205 through the first sliders 204.
[0031] As Figure 4 As shown in the figure, the driving translation assembly 3 includes two first translation members 301 and two second translation members 302. Upper bayonets 3011 are arranged at the upper ends of the first translation members 301 and the second translation members 302. The clamping blocks 801 of the battery pack 8 are clamped by being embedded in the upper bayonets 3011. An inclined surface 3012 is arranged at the upper end of the upper bayonet 3011. A lower bayonet 3013 is arranged at the lower end of the first translation member 301. Second sliders 3014 are arranged on the side surfaces of the first translation members 301 and the second translation members 302. The second sliders 3014 are slidably connected with a second linear guide 3015. The second linear guide 3015 is fixed on the outer side surface of the bottom plate 1. Positioning slots 2031 are arranged at both ends of the push plate 203. The positioning slots 2031 and the lower bayonets 3013 are used in cooperation with each other. Two clamping blocks 801 and three connecting columns 802 are arranged at both ends of the battery pack 8. When assembling the battery pack 8, one clamping block 801 is clamped on the upper bayonet 3011 of the first translation member 301, and the other clamping block 801 is clamped on the upper bayonet 3011 of the second translation member 302. When the push plate 203 performs a linear motion, it will drive the first translation member 301 and the first translation member 301 to perform a linear motion on the second linear guide 3015 through the second sliders 3014, facilitating the movement of the battery pack 8.
[0032] As Figure 5 As shown in the figure, a conveying chain 4 is arranged around the bottom plate. A notch 101 is arranged on the outer end surface of the bottom plate 1. The conveying chain 4 is clamped in the notch, preventing the conveying chain 4 from detaching while allowing the conveying chain 4 to circulate and slide around the bottom plate 1. As Figure 1 As shown in the figure, when the cylinder 201 pushes the battery pack 8 to translate, it also drives the conveying chain 4 to rotate. In this way, the conveying chain 4 and the battery pack 8 move synchronously in translation to carry the battery pack 8 without wearing the battery pack 8.
[0033] On the outer side of the middle of the bottom plate 1, a first sensor detection component 5 is provided. The mounting bracket 12 is arranged on the side of the first sensor detection component 5. On the inner side of one end of the bottom plate 1, a second sensor detection component 6 is provided. On the outer side of the other end of the bottom plate 1, a third sensor detection component 7 is provided. The first sensor detection component 5 is used to detect whether the battery pack 8 is in a locked state. The second sensor detection component 6 is used to detect the in-place situation of the replacement battery pack 8. The third sensor detection component 7 is used to detect the in-place situation of the electric vehicle.
[0034] The unlocking component includes a first telescopic member 14 and a mounting bracket 12. A toggle piece 13 is hinged to the mounting bracket 12. The middle of the toggle piece 13 is hinged to the mounting bracket 12. The first telescopic member 14 abuts against the middle of the toggle piece 13. One end of the toggle piece 13 is hinged to a second telescopic member 16. The other end of the toggle piece 13 corresponds to the lower end of the locking bracket 15. The toggle piece 13 is arc-shaped. By means of the arc-shaped edge of the toggle piece 13, the locking bracket 15 is pushed to move. The first telescopic member 14 is a power telescopic mechanism, and the second telescopic member 16 is an elastic telescopic structure. The second telescopic member 16 is connected with a moving block 17. One end of the moving block 17 is hinged to the toggle piece 13. One end of the moving block 17 is clamped on the conveying chain 4. In the initial state, the toggle piece 13 is in an avoidance state. During the movement of the conveying chain 4, the toggle piece 13 is also driven by the moving block 17 to rotate to a vertical state, and the upper locking bracket 15 is rotated to be unlocked. At the same time, the battery pack 8 is synchronously translated onto the conveying chain 4.
[0035] The power telescopic mechanism is a cylinder or an oil cylinder. The second telescopic member 16 is a gas spring, and the gas spring has a certain buffering effect. When the battery pack 8 moves to the storage position, the first telescopic member 14 extends to push the lower end of the toggle piece 13, causing the toggle piece 13 to rotate relative to the mounting bracket 12, and the upper end of the toggle piece 13 to rotate downward to be in an avoidance state. The second telescopic member 16 will also be stretched as the lower end of the toggle piece 13 rotates. At the same time, an external device will drive the locking bracket 15, the locking piece 10, and the locking block 9 to move downward, so that the connecting column 802 of the battery pack 8 enters the locking slot 901. The battery pack access driving mechanism 2 drives the battery pack 8 to move linearly inward. After the connecting column 802 slides to the inner side of the locking slot 901, the external device drives the locking bracket 15, the locking piece 10, and the locking block 9 to move downward again, causing the locking piece 10 to be received at the locking slot 901 to limit the connecting column 802, so that the battery pack 8 is as Figure 6As shown in the locked state, when the battery needs to be replaced, the first telescopic member 14 contracts and moves away from the toggle piece 13. Under the action of the elastic force of the second telescopic member 16, the toggle piece 13 rotates relative to the mounting frame 12, so that the upper end of the toggle piece 13 rotates upward to lift the locking frame 15, and the locking frame 15 drives the locking piece 10 to move upward, so that the locking piece 10 is away from the connecting column 802. The battery pack access drive mechanism 2 drives the battery pack 8 to move outward in a straight line, so that the connecting column 802 slides to the outside of the locking slot 901, so that the battery pack 8 can be locked. Figure 7 Shown unlocked.
[0036] Working principle: The battery mechanism is installed inside the electric vehicle. When the battery is replaced, when the battery mechanism is docked with the battery replacement equipment and the fully charged battery pack 8 falls onto the conveyor chain 4, the second sensor assembly 6 and the third sensor assembly 7 at the same end feedback a detection signal, indicating that the electric vehicle has completed its position, and the battery mechanism completes the unlocking action of the depleted battery pack 8. The external device drives the locking frame 15, the locking plate 10 and the locking block 9 to move upward, thereby moving the connecting column 802 away from the locking slot 901, completing the removal action of the depleted battery pack 8; after the depleted battery pack 8 is taken out, the fully charged battery pack 8 is clamped with the driving translation assembly 3, and the battery pack storage and retrieval drive mechanism 2 drives the fully charged battery pack 8 to move to the storage position. When the first sensor detection assembly 5 feedbacks a signal, the fully charged battery pack 8 is stored and locked.
[0037] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
