Description

Technical Field

[0001] The utility model relates to the field of battery replacement stations, and in particular to a shuttle-type battery pack replacement device and a battery replacement station comprising the same. Background Art

[0002] In the prior art, battery swap stations are places that provide battery replacement services for new energy electric vehicles. Battery swap stations are usually equipped with battery pack replacement equipment for disassembly and assembly of battery packs and transportation of batteries between battery swap stations and electric vehicles. In the prior art, it is difficult to unify the specifications of battery swap electric vehicles, and the size data and battery pack installation positions of electric vehicles of different specifications are not consistent. For example, the wheelbase of some vehicles is too long and the battery pack is located at the rear of the vehicle body. In this case, the battery pack replacement equipment suitable for conventional vehicles cannot work correctly. The battery pack replacement equipment has poor compatibility, which makes it impossible for battery swap stations to meet the battery replacement needs of vehicles of multiple specifications, thereby increasing the construction cost and use efficiency of battery swap stations. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the defect that the battery pack replacement equipment in the prior art has poor compatibility, which makes the battery swap station unable to meet the battery replacement needs of vehicles of various specifications, thereby increasing the construction cost and utilization efficiency of the battery swap station, and to provide a shuttle-type battery pack replacement equipment and a battery swap station containing the same.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A shuttle type battery pack replacement device is characterized in that it comprises: a base, a motion frame, a driving mechanism and a guiding mechanism;

[0006] The base is movable in a first direction;

[0007] The moving frame is movably connected to the base, and the moving frame is movable in a second direction;

[0008] The driving mechanism is connected to the base and the moving frame respectively, and the driving mechanism is used to drive the moving frame to move relative to the base;

[0009] The guide mechanism is disposed between the base and the moving frame, the guide mechanism extends along the second direction, and the guide mechanism is used to guide the moving frame to move along the second direction;

[0010] The first direction and the second direction are perpendicular to each other in a horizontal plane.

[0011] In this solution, the above structure is adopted. The first direction is the moving direction of the shuttle battery pack replacement equipment, which refers to the direction parallel to the axle. When the base moves to the bottom of the battery replacement vehicle (i.e., the battery replacement position), the driving mechanism drives the motion frame to move along the extension direction of the guide mechanism. The guide mechanism extends along the second direction, and the second direction is perpendicular to the first direction, that is, the motion frame can move toward the direction of the axle. As a result, the motion frame increases the working range of the shuttle battery pack replacement equipment in the second direction. For some vehicle models with a long wheelbase or the battery pack close to the rear side of the vehicle body, precise positioning can be achieved by moving the motion frame without moving the vehicle, which improves the compatibility of the shuttle battery pack replacement equipment and saves the time for positioning the vehicle battery replacement.

[0012] Preferably, the driving mechanism comprises a driving part and a transmission part;

[0013] The driving part is connected to the base, and the transmission part is respectively connected to the motion frame and the driving part, so as to transmit the driving force of the driving part to the motion frame.

[0014] In this solution, the above structure is adopted, and the driving mechanism includes a driving part and a transmission part, and the driving part is connected to the base, and the driving force of the driving part to the moving frame is transmitted through the transmission part, so that the moving frame can move relative to the base.

[0015] Preferably, the transmission part includes a driving member and a driven member;

[0016] The active member is connected to the driving part, and the active member is used to move under the drive of the driving part;

[0017] The driven member is connected to the moving frame, and the driven member is used to move under the drive of the active member.

[0018] In this solution, the above structure is adopted, the driving part drives the active part to move, and the active part drives the driven part to move, and the transmission part is divided into the active part and the driven part, which improves the separability of the transmission part and facilitates maintenance and replacement.

[0019] Preferably, the driving part comprises a motor, the active member comprises a gear, and the driven member comprises a rack;

[0020] The gear is connected to the motor through a transmission shaft, and the rack is meshed with the gear.

[0021] In this solution, the above structure is adopted. The rotation of the motor drives the gear to rotate through the transmission shaft to output the driving force. The rack moves under the drive of the gear. The combination of the motor, gear and rack is simple and effective, and easy to assemble. In addition, the matching accuracy of the rack and the gear is better, and a more accurate stop can be achieved during the movement, which is conducive to the accurate battery replacement of the shuttle battery pack replacement equipment.

[0022] Preferably, the base includes a mounting side wall, and the motion frame includes a first frame;

[0023] The first frame is opposite to the installation side wall;

[0024] The driving mechanism is respectively arranged on the installation side wall and the first frame.

[0025] In this solution, the above structure is adopted, and the driving mechanism is arranged on one side of the moving frame and supported by the mounting side wall of the base, thereby ensuring the reliability and stability of the installation.

[0026] Preferably, the driving mechanism comprises a motor, a gear and a rack;

[0027] The motor is arranged on the mounting side wall, the rack is arranged on the first frame, and the rack extends along the second direction;

[0028] The gear is connected to the motor through a transmission shaft, and the rack is meshed with the gear.

[0029] In the present solution, the above-mentioned structure is adopted, and the mounting side wall provides an installation basis for the setting of the motor. At the same time, a rack is set in the first frame of the moving frame opposite to the mounting side wall. Since the shape of the rack itself has a certain length and directionality, the rack is meshed with the gear, and the distance that the rack moves relative to the gear is the distance that the first frame (or the moving frame) moves relative to the base. Therefore, a rack of appropriate length is selected according to the distance that the moving frame needs to move, and then the rack is set along the second direction that the moving frame needs to move, and the directional and quantitative movement of the moving frame can be completed with the guidance of the guide mechanism.

[0030] Preferably, the rack is arranged above the gear.

[0031] In this solution, the above structure is adopted. Since the gear is located below the rack, under the action of gravity, the rack applies force to the gear, making the meshing between the rack and the gear tighter.

[0032] Preferably, the first frame includes a body and a flange, wherein the flange is connected to the upper portion of the body and extends toward the mounting side wall;

[0033] The rack is fixed to the lower surface of the flange.

[0034] In the present solution, the above-mentioned structure is adopted, and by setting a flange, the rack can be conveniently fixed on the top of the gear, and the transmission components such as the rack and gear can be shielded to prevent external debris from falling between the transmission components from above and affecting their working performance, and make the shuttle-type battery pack replacement equipment more beautiful.

[0035] Preferably, the guide mechanism comprises a slide block and a slide rail;

[0036] The slider is connected to the base and the slide rail is connected to the motion frame, or the slider is connected to the motion frame and the slide rail is connected to the base;

[0037] The sliding block is slidably disposed in the sliding rail, and the sliding rail extends along the second direction.

[0038] In the present solution, the above-mentioned structure is adopted, and the movement between the slider and the slide rail is relative. Regardless of whether the slide rail is installed on the base or the moving frame, as long as the slide rail is set to extend along the second direction, the movement of the slider in the slide rail can guide the moving frame to move along the second direction without affecting the guiding effect, which is convenient for manufacturing and installation.

[0039] Preferably, the base includes a mounting side wall and a supporting wall that are arranged opposite to each other, and the moving frame includes a first frame and a second frame that are arranged opposite to each other;

[0040] The first frame is opposite to the installation side wall, and the second frame is opposite to the support wall;

[0041] The shuttle battery pack replacement device includes two guide mechanisms;

[0042] The two guide mechanisms are respectively arranged between the first frame and the installation side wall and between the second frame and the supporting wall.

[0043] In this solution, the above structure is adopted, and guide mechanisms are respectively set between the first frame and the installation side wall and between the second frame and the support wall, so that the opposite sides of the moving frame can be guided by the guide mechanism, the guiding process is smoother, and the force is more balanced.

[0044] Preferably, the guide mechanism comprises a slider and a slide rail, the slider is slidably disposed in the slide rail, and the slide rail extends along the second direction;

[0045] The first frame includes a first body and a first flange, wherein the first flange is connected to the upper portion of the first body and extends toward the mounting side wall;

[0046] The second frame includes a second body and a second flange, wherein the second flange is connected to an upper portion of the second body and extends toward the supporting wall;

[0047] The two guide mechanisms are respectively arranged below the first flange and the second flange.

[0048] In this solution, the above-mentioned structure is adopted, and by setting a flange, the guide mechanism can be conveniently covered to prevent external debris from falling between the guide mechanisms from above and affecting their working performance, and make the shuttle-type battery pack replacement equipment more beautiful.

[0049] Preferably, the driving mechanism comprises a motor, a gear and a rack;

[0050] The motor is arranged on the mounting side wall, and the gear is connected to the motor via a transmission shaft;

[0051] The rack is arranged on the flange of the first frame, and the rack extends along the second direction;

[0052] The gear is located below the flange, the rack is connected to the lower surface of the flange, and the rack is meshed with the gear.

[0053] In this solution, the above structure is adopted, and the rack extends in the second direction, which is consistent with the extension direction of the slide rail. Therefore, when the rack moves under the drive of the gear, it is guided by the slide rail relative to the slider in the second direction and restricted by the extension direction of the rack itself. The motion frame moves in the second direction as a whole. The cooperation between the driving mechanism and the guide mechanism is efficient and reasonable, the structure is compact, and there is no need to add a steering structure, which does not occupy too much installation space of the shuttle battery pack replacement equipment. In addition, the rack and the slide rail are both set on the flange and move synchronously without collision and interference with each other.

[0054] Preferably, the slide rail located between the first frame and the mounting side wall includes a first slide rail and a second slide rail;

[0055] Along the extending direction of the rack, the first slide rail and the second slide rail are respectively located at two ends of the rack.

[0056] In this solution, the above structure is adopted, and the two sections of the slide rail are arranged at both ends of the rack, so that the support force of the slider on the slide rail or the motion frame is more balanced, and the movement of the motion frame is more stable. In addition, the rack is arranged in the middle of the two sections of the slide rail, and there is no need to rely on the gear to support the rack, which avoids the gear falling off or breaking due to excessive pressure from the rack, and makes the meshing between the rack and the gear more firm.

[0057] Preferably, the first slide rail and the second slide rail are both provided with a limiting block on one side close to the rack.

[0058] In the present solution, the above-mentioned structure is adopted. During the movement of the rack, the slide rail moves synchronously. When the limit block on the slide rail moves to abut against the slider, the rack stops moving. The setting of the limit block limits the maximum moving distance of the rack and also limits the maximum moving distance of the moving frame, thereby preventing the rack from moving excessively and disengaging from the gear, thereby causing the gear to idle, and also preventing the moving frame from moving excessively and colliding with other objects.

[0059] Preferably, the first slide rail and the second slide rail have the same extension length, and the rack has an extension length greater than or equal to the sum of the extension lengths of the first slide rail and the second slide rail.

[0060] In the present solution, the above-mentioned structure is adopted, and the extension lengths of the first slide rail and the second slide rail are the same, so that the moving frame can move the same distance at both ends of the second direction; the extension length of the rack is greater than or equal to the sum of the extension lengths of the first slide rail and the second slide rail, thereby avoiding the situation where the rack is disengaged from the gear before the limit block abuts against the slider due to the rack being too short, resulting in insufficient limit movement distance of the moving frame.

[0061] Preferably, the shuttle battery pack replacement equipment further includes a lifting frame and a jacking mechanism;

[0062] The lifting mechanism connects the moving frame and the lifting frame and lifts the lifting frame relative to the moving frame;

[0063] An unlocking tray is also arranged above the lifting frame.

[0064] In the present solution, the above-mentioned structure is adopted, and the setting of the lifting frame and the lifting mechanism enables the shuttle-type battery pack replacement equipment to also have the possibility of vertical movement. When the base moves along the first direction to the predetermined position under the battery replacement vehicle (i.e., the battery replacement position), the moving frame can adjust its position in the second direction, and the lifting mechanism lifts the lifting frame so that the unlocking tray is aligned with the battery replacement position in the height direction, thereby realizing the precise positioning of the shuttle-type battery pack replacement equipment in the three-dimensional direction.

[0065] Preferably, the lifting mechanism comprises a connecting rod, a first end of the connecting rod is rotatably connected to the lifting frame, and a second end of the connecting rod is rotatably connected to the moving frame.

[0066] In this solution, the above structure is adopted, and the two ends of the connecting rod can rotatably connect the lifting frame and the moving frame. The projection height of the connecting rod in the vertical direction is changed by the rotation of the connecting rod, so that the lifting frame is lifted or returned to its original position relative to the moving frame.

[0067] Preferably, the base, the moving frame and the lifting frame are all rectangular structures, the moving frame is located inside the base, and the lifting frame is located inside the moving frame;

[0068] The moving frame comprises a first frame and a second frame extending along the second direction, and a third frame and a fourth frame extending along the first direction;

[0069] The guide mechanism is connected to the first frame and the second frame respectively, the drive mechanism is connected to the first frame, and the lifting mechanism is connected to the third frame and the fourth frame respectively.

[0070] In this solution, the above structure is adopted, and the base, motion frame and lifting frame are nested layer by layer, so that the movement lines of the motion frame and the lifting frame are reasonable and do not affect each other; the setting positions of the guide mechanism, drive mechanism and lifting mechanism are reasonably arranged in space and do not interfere with each other.

[0071] Preferably, the shuttle-type battery pack replacement equipment also includes a horizontal walking mechanism, and the horizontal walking mechanism is arranged at the bottom of the base.

[0072] In this solution, the above-mentioned structure is adopted, and the setting of the horizontal walking mechanism enables the shuttle-type battery pack replacement equipment to move in a horizontal plane.

[0073] A battery swap station, characterized in that it includes a shuttle battery pack replacement device as described in any of the above items.

[0074] Preferably, the battery swap station further comprises tracks;

[0075] The track extends along the first direction, and the shuttle-type battery pack replacement device is movably disposed on the track and can move to a predetermined position along the extension direction of the track.

[0076] In the present solution, the above-mentioned structure is adopted, and the setting of the track limits the movement of the shuttle battery pack replacement equipment along the first direction. Based on the shuttle battery pack replacement equipment, the working range in the second direction is increased, thereby improving the universality of the battery swap station for battery swap vehicles.

[0077] The positive progressive effect of the present invention is that: through the shuttle battery pack replacement equipment and the battery swap station including the same disclosed by the present invention, the first direction is the moving direction of the shuttle battery pack replacement equipment, which refers to the direction parallel to the axle. When the base moves to the bottom of the battery swap vehicle (i.e., the battery swap position), the drive mechanism drives the motion frame to move along the extension direction of the guide mechanism, and the guide mechanism extends along the second direction, which is perpendicular to the first direction, that is, the motion frame can move toward the direction of the axle. As a result, the motion frame increases the working range of the shuttle battery pack replacement equipment in the second direction. For some vehicle models with a long wheelbase or the battery pack close to the rear side of the vehicle body, precise positioning can be achieved by moving the motion frame without moving the vehicle, which improves the compatibility of the shuttle battery pack replacement equipment and saves the time for positioning the vehicle battery swap.

[0112] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0113] like Figure 1As shown, this embodiment provides a shuttle battery pack replacement device, which includes a base 1, a moving frame 2, a driving mechanism 3 and a guiding mechanism 4. The base 1 is movable in a first direction A. The moving frame 2 is movably connected to the base 1 and movable in a second direction B. The driving mechanism 3 is connected to the base 1 and the moving frame 2 respectively, and the driving mechanism 3 is used to drive the moving frame 2 to move relative to the base 1. The guiding mechanism 4 is arranged between the base 1 and the moving frame 2, and the guiding mechanism 4 extends along the second direction B. The guiding mechanism 4 is used to guide the moving frame 2 to move along the second direction B. Among them, the first direction A of the movement of the base 1 is perpendicular to the second direction B of the movement of the moving frame 2 in the horizontal plane. The first direction A is the moving direction of the shuttle battery pack replacement device, which refers to the direction parallel to the axle. When the base 1 moves to the bottom of the battery replacement vehicle (i.e., the battery replacement position), the driving mechanism 3 drives the moving frame 2 to move along the extension direction of the guiding mechanism 4, and the guiding mechanism 4 extends along the second direction B. The second direction B is perpendicular to the first direction A, that is, the moving frame 2 can move in the direction of the axle. As a result, the motion frame 2 increases the working range of the shuttle-type battery pack replacement equipment in the second direction B. For some vehicle models with a long wheelbase or the battery pack close to the rear side of the vehicle body, precise positioning can be achieved by relying on the movement of the motion frame 2 without moving the vehicle, thereby improving the compatibility of the shuttle-type battery pack replacement equipment and saving time for vehicle battery replacement positioning.

[0114] The movement of the moving frame 2 is relative to the base 1. The movement of the moving frame 2 is driven by the driving mechanism 3 installed on the base 1 and guided by the guiding mechanism 4. The guiding mechanism 4 is fixed on the base 1 and extends along the second direction B. The moving frame 2 is movably connected to the guiding mechanism 4 and can move in the extending direction thereof. The guiding mechanism 4 can limit the movement of the moving frame 2 in directions other than the second direction B, thereby achieving a guiding effect.

[0115] The movement of the base 1 is achieved through its own movement mechanism (i.e., the horizontal walking mechanism 7), and has nothing to do with the movement frame 2. The movement of the base 1 can be achieved by using common solutions in the prior art, such as using wheels or matching tracks. The movement of the base 1 does not interfere with the movement of the movement frame 2.

[0116] like Figure 2As shown, the driving mechanism 3 includes a driving part 31 and a transmission part 32. The driving part 31 is connected to the base 1, and the transmission part 32 is respectively connected to the motion frame 2 and the driving part 31, so as to transmit the driving force of the driving part 31 to the motion frame 2. The driving part 31 is a power source, which is used to generate power to make the motion frame 2 move relative to the base 1, and the driving part 31 is fixedly connected to the base 1. The transmission part 32 is a power transmission mechanism, which is used to transmit the power generated by the driving part 31 to the motion frame 2 and convert it into a driving force to drive the motion frame 2 to move in the second direction B. The transmission part 32 includes an active part and a driven part. The active part and the driven part can be connected in transmission, wherein the active part is connected to the driving part 31 and is directly driven by the output end of the driving part 31. The driven part is fixedly connected to the motion frame 2, and can cooperate with the active part to move synchronously when the active part moves, and convert the movement of the active part into a linear motion along the second direction B. The transmission part 32 is divided into an active part and a driven part, which improves the separability of the transmission part 32 and facilitates maintenance and replacement.

[0117] like Figure 2 As shown, in this embodiment, the driving part 31 includes a motor 311, the active part includes a gear 321, and the driven part includes a rack 322. The gear 321 is connected to the motor 311 through a transmission shaft, and the rack 322 is meshed with the gear 321. The output end of the transmission shaft of the motor 311 faces the first direction A, and the gear 321 is sleeved on the output end of the motor 311. The rack 322 is fixed to the side of the motion frame 2 facing the motor 311 and is arranged horizontally along the second direction B, and it is meshed with the gear 321. The rotation of the motor 311 drives the gear 321 to rotate through the transmission shaft, thereby outputting the driving force, and the rack 322 moves under the drive of the gear 321. The combination of the motor 311, the gear 321, and the rack 322 is simple and effective, and easy to assemble. In addition, the matching accuracy of the rack 322 and the gear 321 is better, and a more accurate stop can be achieved during the movement process, which is conducive to the precise battery replacement of the shuttle battery pack replacement equipment.

[0118] In other embodiments, the transmission part 32 of the driving part 31 may also be replaced by other common movable mechanisms such as a screw rod, and the setting positions of each component may be adaptively adjusted as needed, as long as the movement of the movable frame along the second direction B can be achieved.

[0119] like Figure 1 , 2As shown, the base 1 includes a mounting side wall 11, and the motion frame 2 includes a first frame 21. The first frame 21 is opposite to the mounting side wall 11. The driving mechanism 3 is respectively arranged on the mounting side wall 11 and the first frame 21. The motor 311 is arranged on the mounting side wall 11, and the rack 322 is arranged on the first frame 21, and the rack 322 extends along the second direction B. The gear 321 is connected to the motor 311 through a transmission shaft, and the gear 321 is arranged below the rack 322 and meshes with the rack 322. Since the gear 321 is located below the rack 322, under the action of gravity, the rack 322 applies force to the gear 321, so that the meshing between the rack 322 and the gear 321 is tighter.

[0120] The side of the mounting side wall 11 away from the first frame 21 is used to fix the motor 311 of the driving part 31, and the side of the mounting side wall 11 facing the first frame 21 is used to fix the transmission part 32, that is, the gear 321 of the active part and the rack 322 of the driven part. The transmission shaft of the motor 311 of the driving part 31 passes through the mounting side wall 11 and extends to the other side to connect with the gear 321. The rack 322 is arranged below the motion frame 2 and meshes with the gear 321. The driving mechanism 3 is arranged on one side of the motion frame 2 and supported by the mounting side wall 11 of the base 1 to ensure the reliability and stability of the installation. The mounting side wall 11 provides an installation base for the motor 311. At the same time, a rack 322 is set on the first frame 21 in the motion frame 2 opposite to the mounting side wall 11. Since the shape of the rack 322 itself has a certain length and directionality, the rack 322 is meshed with the gear 321, and the distance that the rack 322 moves relative to the gear 321 is the distance that the first frame 21 (or the motion frame 2) moves relative to the base 1. Therefore, a rack 322 of a suitable length is selected according to the distance that the motion frame 2 needs to move, and then the rack 322 is set along the second direction B that the motion frame 2 needs to move. The directional and quantitative movement of the motion frame 2 can be completed with the guidance of the guide mechanism 4.

[0121] like Figure 3 As shown, the first frame 21 includes a first body 212 and a first flange 211, and the first flange 211 is connected to the upper part of the first body 212 and extends toward the mounting side wall 11. The rack 322 is fixed to the lower surface of the first flange 211. The first body 212 and the first flange 211 are inverted L-shaped, and a receiving space is formed between the lower part of the first flange 211 and the first body 212 for receiving the rack 322 and the gear 321. The rack 322 is arranged at the lower part of the first flange 211, the top of the rack 322 is fixedly connected to the lower part of the first flange 211, the bottom of the rack 322 is meshed with the gear 321, and the first flange 211 and the gear 321 clamp and fix the rack 322 from two opposite directions, so that the fixing effect is better.

[0122] By setting the flange, it is convenient to fix the rack 322 above the gear 321, and the transmission components such as the rack 322 and the gear 321 can be shielded to prevent external debris from falling between the transmission components from above and affecting their working performance, and make the shuttle-type battery pack replacement equipment more beautiful.

[0123] In other embodiments, the first frame 21 may not be provided with a flange but may only have a first body 212 , and the rack 322 may be adaptively mounted directly on the side surface of the first body 212 .

[0124] like Figure 2 , 3 As shown, the guide mechanism 4 includes a slider 41 and a slide rail 42. The slider 41 is connected to the base 1 and the slide rail 42 is connected to the motion frame 2. The slider 41 is slidably disposed in the slide rail 42, and the slide rail 42 extends along the second direction B. Specifically, the slider 41 is fixed on the mounting side wall 11 and extends toward the first frame 21, and the slide rail 42 is installed on the first frame 21, specifically on the main body of the first frame 21. The movement between the slider 41 and the slide rail 42 is relative, and the two are respectively disposed on the first frame 21 and the mounting side wall 11, and can slide relative to each other when the base 1 and the motion frame 2 move relative to each other. It plays a role of limiting and guiding.

[0125] The rack 322 extends along the second direction B, which is consistent with the extension direction of the slide rail 42. Therefore, when the rack 322 moves under the drive of the gear 321, it is guided by the slide rail 42 relative to the slider 41 along the second direction B and is limited by the extension direction of the rack 322 itself. The motion frame 2 moves along the second direction B as a whole. The cooperation between the driving mechanism 3 and the guide mechanism 4 is efficient and reasonable, and the structure is compact. There is no need to add a steering structure, and it does not occupy too much installation space of the shuttle battery pack replacement equipment. In addition, the rack 322 and the slide rail 42 are both set on the flange and move synchronously without collision and interference with each other.

[0126] In other embodiments, the slider 41 is connected to the motion frame 2 and the slide rail 42 is connected to the base 1. Regardless of whether the slide rail 42 is installed on the base 1 or the motion frame 2, as long as the slide rail 42 is set to extend along the second direction B, the movement of the slider 41 in the slide rail 42 can guide the motion frame 2 to move along the second direction B, without affecting the guiding effect, and is easy to manufacture and install.

[0127] In other embodiments, other structures capable of achieving guidance may also be used. For example, instead of providing a separate guiding mechanism 4, the gear 321 and the rack 322 of the driving mechanism 3 may be limited so that the gear 321 cannot move in other directions, which may also achieve the guiding effect.

[0128] like Figure 1As shown, the base 1 includes an installation side wall 11 and a support wall 12 that are arranged opposite to each other, and the moving frame 2 includes a first frame 21 and a second frame 22 that are arranged opposite to each other. The first frame 21 is opposite to the installation side wall 11, and the second frame 22 is opposite to the support wall 12. The shuttle-type battery pack replacement equipment includes two guide mechanisms 4. The two guide mechanisms 4 are respectively arranged between the first frame 21 and the installation side wall 11 and between the second frame 22 and the support wall 12. The first frame 21 corresponds to the installation side wall 11, and the second frame 22 corresponds to the support wall 12, and the two are respectively located on two symmetrical sides. The guide mechanisms 4 are respectively arranged between the first frame 21 and the installation side wall 11 and between the second frame 22 and the support wall 12, so that the opposite sides of the moving frame 2 can be guided by the guide mechanisms 4, the guiding process is smoother, and the force is more balanced.

[0129] like Figure 3 As shown, the slide rail 42 located between the first frame 21 and the mounting side wall 11 includes a first slide rail and a second slide rail (two slide rails 42 are included on both sides of the rack). Along the extension direction of the rack 322, the first slide rail and the second slide rail are respectively located at the two ends of the rack 322. The two sections of the slide rail 42 are respectively arranged at the two ends of the rack 322, so that the support force of the slider 41 on the slide rail 42 or the motion frame 2 is more balanced, and the movement of the motion frame 2 is more stable. In addition, the rack 322 is arranged in the middle of the two sections of the slide rail 42, and there is no need to rely on the gear 321 to support the rack 322, so that the gear 321 is prevented from falling off or breaking due to excessive pressure from the rack 322 on the gear 321, and the meshing between the rack 322 and the gear 321 is more secure.

[0130] like Figure 3 As shown, the first slide rail and the second slide rail are both provided with a limit block 43 on one side close to the rack 322. During the movement of the rack 322, the slide rail 42 moves synchronously. When the limit block 43 on the slide rail 42 moves to abut against the slider 41, the rack 322 stops moving. The setting of the limit block 43 limits the limit moving distance of the rack 322 and also limits the limit moving distance of the motion frame 2, so as to prevent the rack 322 from moving excessively and disengaging from the gear 321, thereby causing the gear 321 to run idle, and also to prevent the motion frame 2 from moving excessively and colliding with other objects.

[0131] like Figure 3 As shown, the first slide rail and the second slide rail have the same extension length, and the extension length of the rack 322 is greater than or equal to the sum of the extension lengths of the first slide rail and the second slide rail. The first slide rail and the second slide rail have the same extension length, so that the moving frame 2 can move the same distance at both ends in the second direction B; the extension length of the rack 322 is greater than or equal to the sum of the extension lengths of the first slide rail and the second slide rail, so as to avoid the rack 322 being separated from the gear 321 before the limit block 43 abuts against the slider 41 due to the rack 322 being too short, resulting in insufficient limit movement distance of the moving frame 2.

[0132] like Figures 1 to 4 As shown, the shuttle-type battery pack replacement equipment also includes a lifting frame 5 and a lifting mechanism 6. The lifting mechanism 6 connects the moving frame 2 and the lifting frame 5 and lifts the lifting frame 5 relative to the moving frame 2. An unlocking tray is also provided above the lifting frame 5. The arrangement of the lifting frame 5 and the lifting mechanism 6 enables the shuttle-type battery pack replacement equipment to also have the possibility of vertical movement. When the base 1 moves along the first direction A to a predetermined position under the battery swap vehicle (i.e., the battery swap position), the moving frame 2 can adjust its position in the second direction B, and the lifting mechanism 6 lifts the lifting frame 5 so that the unlocking tray is aligned with the battery swap position in the height direction, thereby realizing the precise positioning of the shuttle-type battery pack replacement equipment in the three-dimensional direction. The lifting frame 5 is used to carry the battery swap operation equipment, including an unlocking tray, which is used to unlock the battery pack. The lifting frame 5 and the unlocking tray can adopt conventional designs in the prior art, which will not be repeated here.

[0133] like Figure 4 , 5 As shown, the lifting mechanism 6 includes a connecting rod, a first end of which is rotatably connected to the lifting frame 5, and a second end of which is rotatably connected to the moving frame 2. The two ends of the connecting rod are rotatably connected to the lifting frame 5 and the moving frame 2, and the projection height of the connecting rod in the vertical direction is changed by the rotation of the connecting rod, so that the lifting frame 5 is lifted or returned to its original position relative to the moving frame 2.

[0134] like Figure 6 As shown, in this embodiment, the connecting rod is a cam 61, the raised end of the cam 61 is movably connected to the horizontal slide groove 62 on the lifting frame 5, and its connection point can move horizontally in the horizontal slide groove 62 relative to the lifting frame 5. In this structure, when the cam 61 rotates, its raised end can move up and down in the absolute vertical direction, and at the same time slide horizontally in the horizontal slide groove 62, converting the rotational movement of the cam 61 into the vertical movement of the lifting frame 5. At the same time, a limit guide rail 81 and a limit block 82 for limit guide are also provided between the lifting frame 5 and the motion frame 2. The two are respectively connected to the lifting frame 5 and one of the motion frames 2, and can only move in the vertical direction. The lifting frame 5 is lifted and lowered by the cooperation of the limit guide, the cam 61 and the horizontal slide groove 62. This structure occupies little space and is easy to arrange.

[0135] In other embodiments, other conventional lifting methods may also be selected.

[0136] like Figure 1As shown, the base 1, the moving frame 2 and the lifting frame 5 are all rectangular structures, the moving frame 2 is located inside the base 1, and the lifting frame 5 is located inside the moving frame 2. The moving frame 2 includes a first frame 21 and a second frame 22 extending along the second direction B, and a third frame and a fourth frame extending along the first direction A. The guide mechanism 4 is connected to the first frame 21 and the second frame 22 respectively, the drive mechanism 3 is connected to the first frame 21, and the lifting mechanism 6 is connected to the third frame and the fourth frame respectively. The base 1, the moving frame 2 and the lifting frame 5 are nested in layers, so that the moving routes of the moving frame 2 and the lifting frame 5 are reasonable and do not affect each other; the setting positions of the guide mechanism 4, the drive mechanism 3 and the lifting mechanism 6 are arranged in a reasonable spatial layout and do not interfere with each other.

[0137] like Figure 1 As shown, the shuttle-type battery pack replacement device also includes a horizontal walking mechanism 7, which is arranged at the bottom of the base 1. In this embodiment, the horizontal walking mechanism 7 is a plurality of walking wheels arranged on both sides of the base 1 along the second direction B, and these walking wheels can drive the base 1 to move along the first direction A. The walking wheels can move directly on the ground, or they can move in conjunction with the set track. The setting of the horizontal walking mechanism 7 enables the shuttle-type battery pack replacement device to move in a horizontal plane.

[0138] The present embodiment also provides a battery swap station, which includes the above shuttle battery pack replacement equipment. The battery swap station also includes a track. The track extends along a first direction A, and the shuttle battery pack replacement equipment is movably arranged on the track and can be moved to a predetermined position along the extension direction of the track. The setting of the track limits the movement of the shuttle battery pack replacement equipment along the first direction A, and based on the shuttle battery pack replacement equipment, the working range in the second direction B is increased, so that the universality of the battery swap station for battery swap vehicles is improved.

[0139] In other embodiments, the battery swap station may not be equipped with tracks, and the shuttle battery pack replacement equipment moves independently through a walking mechanism.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
