Description

Technical Field

[0001] The present invention relates to the technical field of battery swapping stations, and particularly to a moving mechanism and a battery swapping station. Background Art

[0002] During the battery swapping operation, the battery swapping robot needs to travel along a track, back and forth between the battery storage location and the battery installation location, to grasp the battery on the battery transport vehicle parked at the battery storage location and transport the battery to the operating vehicle parked at the battery installation location.

[0003] Therefore, generally, a guide rail is laid in the battery swapping station. The guide rail extends along a first horizontal direction, and a rack is provided on one side of the guide rail in a second horizontal direction. The battery swapping robot is installed on a carrier. The housing of the carrier is located above the guide rail. A driving assembly is installed in the installation cavity of the housing. The driving member in the driving assembly drives an output gear through a transmission member. The output gear meshes and drives with the meshing teeth. Since the guide rail is relatively fixed to the ground, in this way, the output gear drives the housing to travel along the rack.

[0004] Due to problems such as processing, assembly, and use scenarios, the rack will be deformed, making the meshing teeth uneven in the second horizontal direction. When the output gear meshes and drives with the meshing teeth, the meshing reliability between the output gear and the meshing teeth is reduced, resulting in the actual travel distance of the housing not matching the theoretical travel distance, that is, it cannot accurately reach the specified position and requires manual assistance.

[0005] Therefore, there is an urgent need for a moving mechanism and a battery swapping station to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a moving mechanism and a battery swapping station, which can compensate for the deformation of the rack, thereby improving the accuracy and reliability of the transmission between the output gear and the meshing teeth.

The two limiting rods are arranged at intervals in the tooth width direction, and the limiting plate is clamped between the two limiting rods.

[0016] As a preferred technical solution of the moving mechanism, the two limiting rods are sleeved with second limiting bearings, and the limiting plate is clamped between the peripheral side walls of the outer rings of the two second limiting bearings.

[0018] As a preferred technical solution of the moving mechanism, the drive member is connected to the mounting bracket through a flange.

[0019] A battery swapping station is also provided, including a battery swapping robot and the above-mentioned moving mechanism. The battery swapping robot is fixed to the side of the housing facing away from the rack.

[0020] As a preferred technical solution of the above-mentioned moving mechanism, it further includes a guide rail. The guide rail includes an engaging track and a sliding track. The engaging track and the sliding track are parallel to the extension direction of the guide rail. The rack is arranged on the engaging track. The housing is rotatably connected with a driven wheel.

[0037] The following will further elaborate on the present invention in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

[0038] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0040] In the description of this embodiment, the orientation or positional relationships such as "above", "below", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, so it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0041] As Figures 1 to 4 shown, the present application provides a moving mechanism, including a rack 11, a housing 20, a mounting bracket 30, and a driving assembly 40. Among them, the rack 11 includes a plurality of meshing teeth, and the plurality of meshing teeth are continuously distributed along the extending direction of the rack 11; a first support frame 22 and a second support frame 23 are provided on the housing 20; the mounting bracket 30 is hinged to the first support frame 22 through a hinge shaft 31, and the axis of the hinge shaft 31 is parallel to the tooth width direction of the meshing teeth, and the mounting bracket 30 is lapped on the second support frame 23 in the vertical direction; the driving assembly 40 includes a driving member 41, a transmission member 42, and an output gear 43. The driving member 41 and the transmission member 42 are both mounted on the mounting bracket 30, the driving member 41 is in transmission connection with the output gear 43 through the transmission member 42, and the output gear 43 meshes with the meshing teeth for transmission.

[0042] Specifically, in this embodiment, the rack 11 extends along the first horizontal direction, and the meshing teeth are arranged on one side of the rack 11 in the second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction, and the tooth width direction of the meshing teeth is perpendicular to the vertical direction. The housing 20 is located above the rack 11. A driving assembly 40 is installed in the installation cavity of the housing 20. The driving member 41 in the driving assembly 40 drives the output gear 43 through the transmission member 42. The output gear 43 meshes and drives with the meshing teeth. Since the rack 11 is relatively fixed to the ground, in this way, the output gear 43 drives the housing 20 to travel along the rack 11.

[0043] Furthermore, due to problems such as processing, assembly, and use scenarios, the rack 11 will deform, causing the meshing teeth to be uneven in the second horizontal direction. When the output gear 43 meshes and drives with the meshing teeth, the meshing reliability between the output gear 43 and the meshing teeth is reduced, resulting in the actual travel distance of the housing 20 not matching the theoretical travel distance, that is, it cannot accurately reach the designated position and requires manual assistance.

[0044] Therefore, in this embodiment, a first support frame 22 and a second support frame 23 are fixed in the first installation cavity 21 of the housing 20. The first support frame 22 and the second support frame 23 are respectively fixed on the opposite side walls of the housing 20 in the first horizontal direction. The driving assembly 40 is installed on the mounting frame 30. One end of the mounting frame 30 is hinged to the first support frame 22, and the axis of the hinge shaft 31 is parallel to the vertical direction. The other end of the mounting frame 30 is supported by the second support frame 23 below in the vertical direction, and the mounting frame 30 can slide relative to the second support frame 23 in the horizontal direction.

[0045] In this way, the hinge of the mounting frame 30 with the first support frame 22 and the relative sliding with the second support frame 23 enable the driving assembly 40 to have the freedom of swinging in the horizontal direction. The output gear 43 can swing adaptively with the undulation of the rack 11 in the second horizontal direction, and the second support frame 23 plays a supporting role for the mounting frame 30 to prevent local overloading and damage of the hinge shaft 31. Furthermore, through the swinging of the output gear 43, the deformation of the rack 11 in the second horizontal direction is compensated, thereby improving the accuracy and reliability of the transmission between the output gear 43 and the meshing teeth.

[0046] In other embodiments, the first support frame 22 and the second support frame 23 are respectively fixed on the adjacent side walls of the installation cavity.

[0047] In other embodiments, the first support frame 22 and / or the second support frame 23 are provided with waist-shaped holes. The length direction of the waist-shaped holes is parallel to the second horizontal direction. One end of the mounting frame 30 is provided with a plug pin, and the plug pin can be inserted into the waist-shaped hole and can slide relative to the first support frame 22 along the length direction of the waist-shaped hole. In this way, the mounting frame 30 can be displaced relative to the housing 20 in the second horizontal direction.

[0048] Further, the moving mechanism further includes a first limiting bearing 50. The first limiting bearing 50 is rotatably connected to the mounting frame 30. The rack 11 is clamped between the first limiting bearing 50 and the meshing teeth. The axis of the meshing teeth is parallel to the axis of the first limiting bearing 50. The mounting seat is rotatably connected with the first limiting bearing 50. The first limiting bearing 50 and the output gear 43 are arranged at intervals in the second horizontal direction. The rack 11 is clamped between the first limiting bearing 50 and the output gear 43. The first limiting bearing 50 enables the output gear 43 to always remain meshed with the meshing teeth. It can avoid the situation that the output gear 43 and the meshing teeth are disengaged in the second horizontal direction during rapid movement.

[0049] Specifically, the distance from the busbar of the first limiting bearing 50 close to the output gear 43 in the second horizontal direction to the tooth tip on the side of the output gear 43 close to the first limiting bearing 50 is D1. In the second horizontal direction, the distance from the abutting end face of the rack 11 and the first limiting bearing 50 to the tooth bottom of the meshing teeth is L1, and the distance to the tooth tip of the meshing teeth is L2, satisfying L1 ≤ D1 < L2.

[0050] In other embodiments, the rack 11 is erected on the ground. The meshing teeth can be arranged on one side in the vertical direction of the rack 11. The output gear 43 and the first limiting bearing 50 are arranged at intervals on opposite sides of the rack 11 in the vertical direction.

[0051] Optionally, the first support frame 22 includes two first connecting ears 221. The mounting frame 30 protrudes with a second connecting ear 32. The hinge shaft 31 is sequentially connected to one of the first connecting ears 221, the second connecting ear 32, and the other first connecting ear 221 along its axial direction. And the distance between the two first connecting ears 221 is less than the tooth width of the meshing teeth. In this way, the second connecting ear 32 of the mounting frame 30 is clamped between the two first connecting ears 221 of the first support frame 22, which not only facilitates the hinging of the first support frame 22 and the mounting frame 30, but also the two first connecting ears 221 can limit the displacement range of the second connecting ear 32 in the vertical direction to avoid the output gear 43 carried by the mounting seat being disengaged from the meshing teeth in the vertical direction.

[0052] Preferably, the opposite end faces of the second connecting ear 32 are respectively abutted against the end faces of the two first connecting ears 221.

[0053] Preferably, the mounting frame 30 protrudes with two second connecting ears 32. The lower connecting ear of the two second connecting ears 32 is located between the two first connecting ears 221, or both of the two second connecting ears 32 are located between the two second connecting ears 32.

[0054] Optionally, the first connecting ear 221 and / or the second connecting ear 32 are connected to the hinge shaft 31 through bearings. Specifically, the hinge shaft 31 is in interference fit with the inner ring of the bearing, and the outer ring of the bearing is in interference fit with the through holes provided in the first connecting ear 221 and / or the second connecting ear 32. In this way, the relative swing of the mounting bracket 30 and the housing 20 is more sensitive through the bearing connection.

[0055] Optionally, the second support frame 23 includes a support beam 231 and a limiting plate 232. One axial end of the support beam 231 is fixed to the side wall of the housing 20, and the other end is fixed with the limiting plate 232. The mounting bracket 30 protrudes two limiting rods 33, and the two limiting rods 33 are arranged at intervals along the tooth width direction. The limiting plate 232 is clamped between the two limiting rods 33. With such a setting, the limiting plate 232 can limit the swing of the two limiting rods 33 in the tooth width direction, that is, both the first support frame 22 and the second support frame 23 can limit the swing of the mounting bracket 30 in the tooth width direction, avoiding the output gear 43 from disengaging from the meshing teeth along the tooth width direction.

[0056] Optionally, the two limiting rods 33 are sleeved with second limiting bearings 34, and the limiting plate 232 is clamped between the peripheral side walls of the outer rings of the two second limiting bearings 34. Specifically, the limiting rod 33 is in interference fit with the inner ring of the second limiting bearing 34, and the peripheral side wall of the outer ring of the second limiting bearing 34 can abut against and slide relative to the limiting plate 232. In this way, through the second limiting bearing 34, the friction between the limiting rod 33 and the limiting plate 232 is reduced, making the relative swing of the mounting bracket 30 and the housing 20 more sensitive.

[0057] Optionally, the mounting bracket 30 is provided with a receiving cavity 35. The transmission member 42 includes an input shaft, an output shaft, a driving gear and a driven gear. The input shaft and the output shaft are both rotatably connected to the mounting bracket 30. The input shaft is coaxially connected to the output end of the driving member 41 and the driving gear, the output shaft is coaxially connected to the driven gear and the output gear 43, and the driving gear and the driven gear are meshed and transmitted in the receiving cavity 35.

[0058] Specifically, the input shaft and the output shaft are arranged in parallel. The axial two ends of the input shaft and the output shaft are both rotatably connected to the mounting bracket 30. The input shaft is coaxially sleeved with the driving gear, and one end of the input shaft is in transmission connection with the output end of the driving member 41. The output shaft is coaxially sleeved with the driven gear and the output gear 43. The output gear 43 is located outside the receiving cavity 35 and is meshed and transmitted with the meshing teeth. In this way, when the driving member 41 outputs kinetic energy, its output end drives the input shaft to rotate around its own axis. The driving gear rotates with the input shaft. The driving gear and the driven gear are meshed and transmitted, so that the output shaft drives the output gear 43 to rotate together. Since the rack 11 is generally relatively fixed to the ground, the output gear 43 carries the housing 20 to move along the rack 11.

[0059] Optionally, the driving member 41 and the mounting bracket 30 are connected by a flange. In this way, with the flange connection, there are multiple fixing points between the driving member 41 and the mounting bracket 30, making the fixing relationship more reliable.

[0060] A battery swapping station is also provided, which includes a battery swapping robot and the above-mentioned moving mechanism. The battery swapping robot is fixed on the side of the housing 20 facing away from the rack 11.

[0061] Optionally, the battery swapping station further includes a guide rail 10. The guide rail 10 includes an engaging track and a sliding track 12. The engaging track and the sliding track 12 are parallel to the extending direction of the guide rail 10. The rack 11 is arranged on the engaging track. The housing 20 is rotatably connected with a driven wheel 24. A limiting groove is formed around the circumferential side of the driven wheel 24. The sliding track 12 is inserted into the limiting groove and relatively slides with the driven wheel 24, and the axis of the driven wheel 24 is perpendicular to the axis of the output gear 43.

[0062] Specifically, the guide rail is in an I shape and includes a first horizontal support portion, a second horizontal support portion, and a vertical support portion. Among them, the first horizontal support portion and the second horizontal support portion are arranged parallel to the horizontal plane. The first horizontal support portion is fixed to the ground. The vertical support portion connects the first horizontal support portion and the second horizontal support portion in the middle and forms grooves on the opposite sides in the first horizontal direction. The rack is fixed in one of the grooves. The rack is provided with engaging teeth, and the engaging teeth face away from the vertical support portion. The axis of the output gear 43 is parallel to the vertical direction, and the axis of the driven wheel 24 is parallel to the horizontal direction. A limiting groove is formed around the axis of the driven wheel 24 on its circumferential side wall. The bottom of the limiting groove abuts against and relatively slides with the second horizontal support in the vertical direction. In this way, the rack forms an engaging track for the output gear 43 to travel, and the second horizontal support portion forms a sliding track 12 for the driven wheel 24 to travel. The limiting groove of the driven wheel 24 limits the relative swing of the driven wheel 24 relative to the guide rail 10 in the first horizontal direction, so that it can only travel along the extending direction of the guide rail 10. And the driven wheel 24 supports the housing 20 in the vertical direction, reducing the friction between the housing 20 and the guide rail 10 in the vertical direction.

[0063] Further, the housing 20 is further provided with a second installation cavity, and the driven wheel 24 is installed in the second installation cavity. In this way, during the running process, it is avoided that the driven wheel 24 splashes debris into the first installation cavity 21, affecting the operation of the transmission component.

[0064] Optionally, the guide rail 10 extends in the horizontal direction. In the vertical direction, the center of gravity of the driving component 40 is located within the positive projection of the guide rail 10. In this way, it is avoided that due to the offset of the center of gravity of the driving component 40, the mounting bracket 30 always has a tendency to tilt towards the side where the center of gravity is offset, and further, the output gear 43 is over-pressed against the engaging teeth or partially loosened.

[0065] In addition, the above are only the preferred embodiments of the present invention and the technical principles applied. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein. Various obvious changes, re-adjustments and substitutions can be made by those skilled in the art without departing from the protection scope of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments only. Without departing from the concept of the present invention, more other equivalent embodiments can be included, and the scope of the present invention is determined by the scope of the appended claims.
