DETAILED DESCRIPTION

[0040] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0042] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships described in the embodiments and shown in the accompanying drawings, or are directions or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0043] like Figure 1-Figure 10As shown, the present invention specifically relates to a parallel lateral battery swap station, including a battery swap compartment and a battery compartment 200, wherein the battery compartment 200 has an energy storage base device 300 for storing and charging batteries and a frame-type battery swap mechanical actuator for transporting batteries on the energy storage base device 300;

[0044] The frame-type mechanical actuator 400 includes a lower motion assembly 410, an upper motion assembly 420 connected to the lower motion assembly 410, and a battery grabbing tool 430 disposed on the upper motion assembly 420;

[0045] The lower moving assembly 410 drives the upper moving assembly 420 and the battery grabbing tool 430 to move to the energy storage base device 300 , and the upper moving assembly 420 drives the battery grabbing tool 430 to move above the battery, and the battery is transported by the battery grabbing tool 430 .

[0046] It should be noted that the vehicle enters the battery swap compartment to wait for the battery 100 to be replaced. There are multiple battery packs in the battery compartment 200, and each battery pack has an independent energy storage base device 300. The battery pack is fixed and charged separately through the energy storage base device 300. The specific structure of the energy storage base device 300 is a commonly used technical means in the prior art and will not be described in detail.

[0047] The frame-type mechanical actuator 400 is arranged on one side of the energy storage base device 300, wherein the energy storage base device 300 is arranged in parallel. Therefore, the frame-type mechanical actuator 400 can reach the position of each energy storage base device 300 through linear movement to move the batteries on the energy storage base device 300.

[0048] Among them, the main function of the lower motion component 410 is to execute the moving command to reach the specified position of the energy storage base device 300, and the main function of the upper motion component 420 is not only to provide support for the battery grabbing tooling 430, but also to adjust the position of the battery grabbing tooling 430 so as to move the battery grabbing tooling 430 to the top of the battery, fix the battery through the battery grabbing tooling 430, and then cooperate with the upper motion component 420 and the lower motion component 410 to complete the battery transportation.

[0049] The lower motion assembly 410 includes a guide rail 412 and a lower support base 411 that moves linearly on the guide rail 412 via running wheels. The lower support base 411 is connected to the upper motion assembly 420 via a large plate 414 .

[0050] The lower support base 411 moves linearly on the guide rail 412 via the running wheels, thereby driving the upper motion assembly 420 and the battery grabbing tool 430 to move synchronously to the designated energy storage base device 300 position.

[0051] In addition, the lower support base 411 is also provided with a driving motor for driving the travel wheels to move. The specific connection relationship belongs to a very mature existing technology, so it will not be described in detail.

[0052] The lower support base 411 is provided with a rotating shaft 413, one end of the large plate 414 is fixed to the rotating shaft 413, and the other end of the large plate 414 is fixed to the bottom of the upper moving assembly 420;

[0053] The lower support base 411 is further provided with a power drive assembly 415, and the telescopic end of the power drive assembly 415 is connected to the upper motion assembly 420 through a movable pin assembly; the rotation angle of the rotating shaft 413 is ±5°.

[0054] The power drive component 415 in this embodiment is a cylinder. Since the upper motion component 420 is connected to the rotating shaft 413 through the large plate 414, when the telescopic end of the cylinder applies external force to the upper motion component 420, the upper motion component 420 can rotate along the axial direction of the rotating shaft 413.

[0055] When a vehicle enters the battery swapping compartment, the actual parking position may have a certain angle deviation from the specified required position. The rotating shaft 413 is rotated to solve the problem of the tilt of the parking position of the new energy vehicle in the battery swapping area in the channel.

[0056] The upper motion assembly 420 includes an upper support frame 421 and a bidirectional telescopic fork assembly 422 disposed on the upper support frame 421 . The bidirectional telescopic fork assembly 422 is connected to the battery grabbing fixture 430 and can drive the battery grabbing fixture 430 to linearly translate.

[0057] The two-way telescopic fork assembly 422 can linearly translate the parts on the fork forward and backward or left and right to complete the position change. The two-way telescopic fork assembly 422 is used to move the battery on the battery swap vehicle to the battery compartment 200; in addition, the fully charged battery in the battery compartment 200 is moved to the vehicle.

[0058] Of course, the lower moving assembly 410 is also needed in the above-mentioned translation process, and the battery can be moved to the designated replacement or placement position only through the lower moving assembly 410.

[0059] The battery grabbing tool 430 includes a lifting and adjusting device 431 and a sling 432 connected to the lifting and adjusting device 431 through a steel wire rope 4314;

[0060] The lifting adjustment device 431 includes a lifting adjustment support seat 4311, on which a movable pulley assembly 4313 and a fixed pulley assembly 4312 are provided. One end of the steel wire rope 4314 is connected to the sling 432 through a link assembly, and the other end of the steel wire rope 4314 is sequentially wound around the fixed pulley assembly 4312 and the movable pulley assembly 4313 and fixed to the horizontal adjustment assembly 4315.

[0061] The horizontal adjustment component 4315 is slidably connected to the lifting adjustment support base 4311, and the lifting adjustment support base 4311 is provided with a lifting driving component 4316 for driving the horizontal adjustment component 4315 to move linearly.

[0062] Among them, the lifting and adjustment support seat 4311 is fixed on the bidirectional telescopic fork assembly 422, and the wire rope 4314 passes through the lifting and adjustment support seat 4311 and is connected to the sling 432 through the link assembly to fix the sling 432. In order to ensure the smoothness of the wire rope 4314 during the telescopic process, a fixed pulley assembly 4312 and a movable pulley assembly 4313 used in conjunction with the wire rope 4314 are provided on the lifting and adjustment support seat 4311. The wire rope 4314 is wrapped around the fixed pulley assembly 4312 and the movable pulley assembly 4313 and is fixed to the horizontal adjustment assembly 4315.

[0063] In addition, the lifting drive assembly 4316 is a structure that can drive the linear movement of parts, which can be a cylinder, an oil cylinder or a motor, etc., and will not be described in detail here.

[0064] When the lifting drive assembly 4316 drives the horizontal adjustment assembly 4315 to move linearly relative to the lifting adjustment support seat 4311, the horizontal adjustment assembly 4315 drives the wire rope 4314 to rotate relative to the fixed sliding assembly and the movable pulley assembly 4313, thereby driving the sling 432 to rise or fall.

[0065] The hanger 432 is provided with an inclination sensor to monitor the levelness of the hanger 432 and further monitor the levelness of the battery relative to the ground during the lifting process.

[0066] The horizontal adjustment assembly 4315 includes a horizontal adjustment platform 43151 slidably connected to the lifting adjustment support seat 4311, and the horizontal adjustment platform 43151 is provided with a motor linear module 43152 and a rope support seat 43153 connected to the motor linear module 43152;

[0067] One of the steel wire ropes 4314 on the same side of the sling 432 is connected to the horizontal adjustment platform 43151 , and the other steel wire rope 4314 on the same side of the sling 432 is connected to the rope support seat 43153 .

[0068] It should be noted that, the steel wire ropes 4314 on the same side of the sling 432 are wound around the same fixed pulley assembly 4312 and movable pulley assembly 4313 , wherein one of the steel wire ropes 4314 is fixedly connected to the horizontal adjustment platform 43151 , and the other steel wire rope 4314 is connected to the rope support seat 43153 .

[0069] When the horizontality of the sling 432 is normal, since the rope support seat 43153 is arranged on the horizontal adjustment platform 43151, when the horizontal adjustment platform 43151 moves, the support seat is driven to move synchronously to complete the lifting and lowering of the sling 432. During this process, the motor linear module 43152 will not start, and the position of the rope support seat 43153 relative to the horizontal adjustment platform 43151 will not change.

[0070] When the levelness of the sling 432 is abnormal, the position of the rope support seat 43153 relative to the horizontal adjustment platform 43151 is adjusted by the motor linear module 43152, thereby adjusting the levelness of the sling 432. During this process, the position of the horizontal adjustment platform 43151 relative to the lifting adjustment support seat 4311 will not change.

[0071] A guide fixing assembly 4317 is provided at the bottom of the lifting and adjusting support seat 4311, and a guide column 4324 is provided on the upper end face of the sling 432 for cooperating with the guide fixing assembly 4317. Since the steel wire rope 4314 is a flexible transmission, the guide column 4324 and the guide fixing assembly 4317 cooperate with each other as a guide to fix the guide column 4324 and the guide fixing assembly 4317 to make it rigidly connected, thereby ensuring that no shaking occurs during the transportation of the battery.

[0072] The hanger 432 has a fixed frame 4321 , and the fixed frame 4321 is provided with a plurality of positioning guide blocks 4322 and a rotating locking tongue 4323 . The fixed frame 4321 is also provided with a rotating driving component 4325 for driving the rotating locking tongue 4323 to rotate.

[0073] The battery is limited by the directional guide block, and the locking tongue is driven to rotate by the rotary drive assembly 4325 to lock the battery. This structure has been used to a certain extent in the prior art, so it will not be described in detail.

[0074] The above embodiments are only specific implementation methods of the present invention, which are used to illustrate the technical solutions of the present invention rather than to limit them. The protection scope of the present invention is not limited thereto. Although the present invention has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the aforementioned embodiments within the technical scope disclosed by the present invention, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be covered within the protection scope of the present invention.
