Description

Technical Field

[0001] The present invention belongs to the field of battery replacement technology, and specifically relates to a battery pack charging rack and a mobile battery replacement station. Background Art

[0002] With the rapid development of the new energy vehicle industry, mobile battery swapping has become a key solution to addressing electric vehicle range concerns, and market demand is growing. In mobile battery swapping systems, battery pack storage, charging, and rapid turnover are key components for ensuring efficient swapping. Battery pack charging racks, as key equipment for battery pack storage and charging, have a structural rationality that directly impacts the stability and economic efficiency of the battery swap process.

[0003] Currently, the mainstream battery pack charging racks in the industry are mainly divided into two categories: beam racks and automated racks. Beam racks are a storage structure formed by combining two vertical frames with horizontal beams. Battery packs are typically placed directly on the beams for stacked storage. While this structure offers low manufacturing costs and a simple construction, it has significant drawbacks in practice. Firstly, charging is difficult due to the close contact between the battery packs and the beams, lacking dedicated docking space for charging ports. This requires frequent manual plugging and unplugging of charging cables, which is not only inefficient but also poses a safety risk of electric shock. Secondly, battery pack handling is difficult. The beam rack structure lacks auxiliary handling mechanisms, making manual handling of heavy battery packs prone to fatigue. Furthermore, accessing and placing upper battery packs in stacks requires external lifting equipment, severely limiting battery replacement efficiency. Another mainstream solution is automated racks, which use automated equipment such as rails, robotic arms, or shuttles to automatically transport battery packs between storage, charging, and retrieval stations. Charging is completed at a fixed charging station, while retrieval and placement are performed at independent stations. Although this solution can improve the degree of automation, it has problems of complex structure and high cost: automated shelves need to integrate sophisticated transmission systems, control systems and positioning devices, with a large number of parts and high processing precision requirements, resulting in a significant increase in equipment manufacturing costs; at the same time, the complex mechanical structure also increases the difficulty of equipment maintenance. Failure in any link may cause the entire shelf system to stop operating, affecting the continuity of battery swap services, and it is difficult to popularize and apply it in small and medium-sized battery swap stations.

[0004] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0005] The object of the present invention is to provide a battery pack charging rack, which is used to solve the problems of difficulty in taking and placing batteries and complex structure of existing racks.

[0006] To achieve the above object, one specific embodiment of the present application provides a battery pack charging rack, which comprises a plurality of bearing frames, a side frame, a plurality of battery sliding rails and a plurality of locking mechanisms. The plurality of bearing frames are arranged in sequence along a preset direction. The side frame is connected to the side of the plurality of bearing frames.

The elastic member is connected to the locking member and the fixed block. When the locking mechanism is in the locking state and the unlocking state, the elastic member is in a stretched state.

[0011] In one or more embodiments of the present application, the elastic member is stretched in a horizontal direction when the locking mechanism is in the locked state.

[0012] In one or more embodiments of the present application, the locking mechanism further comprises a mounting seat provided on the top of the battery slide rail, a second opening is provided through the mounting seat and is in communication with the first opening, and the pivot shaft is provided in the second opening.

[0013] In one or more embodiments of the present application, the battery pack charging rack further comprises a connector provided on the side frame, and the connector is used to electrically connect the battery pack and the charging source.

[0014] In one or more embodiments of the present application, the battery pack charging rack further comprises a positioning member provided on the side of the battery slide rail away from the side frame, and a positioning hole is provided on the positioning member and is used to cooperate with a horizontally movable positioning pin on the battery pack taking and placing device.

[0015] In one or more embodiments of the present application, a plurality of side frames are provided, and each side frame is connected with two adjacent bearing frames.

[0016] In one or more embodiments of the present application, the battery pack charging rack further comprises a top connecting structure connecting the adjacent two bearing frames, and the top connecting structure is a frame structure or a beam structure.

The battery swap truck comprises a vehicle cabin, and the battery pack charging rack is arranged in the vehicle cabin, and a plurality of bearing frames are arranged along the length direction of the vehicle cabin.

[0018] Compared with the prior art, the present application has a simple structure and low manufacturing cost. The battery slide rail can stably support the battery pack, and the working state of the locking mechanism is switched to cooperate with the battery pack taking and placing device to take and place the battery pack, thereby reducing the difficulty of taking and placing the battery pack and improving the efficiency of taking and placing the battery pack.

DETAILED DESCRIPTION

[0028] In order to enable persons skilled in the art to better understand the technical solutions in the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by persons skilled in the art without creative labor should fall within the protection scope of the present disclosure.

[0029] In the description of the present application, it should be understood that the terms "top", "bottom", "upper", "lower" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0030] In addition, the terms "second", "first" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "second", "first" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0031] Referring to Figures 1 to 3 As shown in the drawings, an embodiment of the present application provides a battery pack charging rack for storing battery packs, the battery pack being generally a square prism, the battery pack being provided with a roller 8 on both sides, the battery pack charging rack comprising a plurality of bearing frames 1, a side frame 2, a top connecting structure 6, a plurality of battery slide rails 3 and a plurality of locking mechanisms 4.

[0032] Specifically, the plurality of bearing frames 1 are arranged in sequence along a preset direction, the preset direction being generally parallel to the horizontal plane, and a storage space for storing the battery pack is formed between the adjacent two bearing frames 1. The side frame 2 is connected to the side of the plurality of bearing frames 1, and the top connecting structure 6 is connected to the top of the plurality of bearing frames 1, and the top connecting structure 6 can be provided as a frame structure or a beam structure. The plurality of battery slide rails 3 are respectively arranged on the side of each bearing frame 1 facing the other bearing frame 1 adjacent thereto, for example, three bearing frames 1 are arranged in sequence from left to right, then the battery slide rail 3 is installed on the right side of the left bearing frame 1, the battery slide rails 3 are installed on the left and right sides of the middle bearing frame 1, and the battery slide rail 3 is installed on the left side of the right bearing frame 1. The two oppositely arranged battery slide rails 3 cooperate with each other to carry the same battery pack, and a sliding groove 31 is formed on the side wall of the battery slide rail 3, the sliding groove 31 extends to the side of the battery slide rail 3 away from the side frame 2 to form an entrance and exit 32, and the sliding groove 31 is used to cooperate with the roller 8 of the battery pack, so that the battery pack can be controlled to move along the battery slide rail 3. The plurality of locking mechanisms 4 are correspondingly arranged on the plurality of battery slide rails 3, and the locking mechanism 4 comprises a lock piece 41 which can be controlled to pivot, and the locking mechanism 4 has a locking state and an unlocking state.

[0033] According to the above structure design, when the locking mechanism 4 is in the locking state, the lock piece 41 is at least partially located in the sliding groove 31 and is located in the moving path of the roller 8 of the battery pack, which limits the roller 8 of the battery pack to move out of the sliding groove 31 through the entrance and exit 32, fixes the battery pack on the battery slide rail 3, and stores the battery pack.

[0034] When the locking mechanism 4 is in the unlocked state, the locking piece 41 can be controlled to pivot around its pivot shaft 42 and move out of the chute 31, at this time the rollers 8 of the battery pack are no longer restricted by the locking piece 41, under the drive of the battery pack taking and placing device or manual carrying, the rollers 8 of the battery pack can roll along the chute 31 and escape from the battery slide rail 3 through the exit 32 on the battery slide rail 3, so as to take the battery pack off the battery slide rail 3. Of course, when it is needed to store the battery pack on the battery pack charging shelf, it is needed to switch the locking mechanism 4 to the unlocked state, align the rollers 8 of the battery pack with the exit 32 on the battery slide rail 3, then push the battery pack so that the rollers 8 of the battery pack enter the chute 31, and then switch the locking mechanism 4 to the locked state.

[0035] In an embodiment, referring to Fig. 1, the carrying frame 1 is composed of a plurality of steel beams or steel columns arranged in a crisscross manner, and the carrying frame 1 is generally arranged in a rectangular steel structure. A plurality of side edge frames 2 are arranged, each of which is connected to two adjacent carrying frames 1, and the side edge frame 2 is also composed of a plurality of steel beams or steel columns arranged in a crisscross manner, and is also generally arranged in a rectangular steel structure. A plurality of top connecting structures 6 are arranged, each of which is connected to two adjacent carrying frames 1. Figure 1 Further, a waist-shaped hole is arranged on the side edge frame 2 and the top connecting structure 6, and a bolt is screwed into a threaded hole on the carrying frame 1 through the waist-shaped hole, so as to fixedly connect the side edge frame 2 and the top connecting structure 6 to the carrying frame 1. The bottom of the carrying frame 1 is provided with a height adjusting mechanism, so as to adjust the height of the carrying frame 1.

[0036] Further, when the carrying frame 1 is arranged in three or more, the length, width and height of each storage space (i.e. the space between two adjacent carrying frames 1) can be the same or different, and can be flexibly adjusted according to the model and size of the battery pack.

[0037] It should be noted that the structure of the carrying frame 1 and the side edge frame 2 in the above embodiment is one scheme that can be selected in actual application, and for those skilled in the art, under the premise of not deviating from the technical principles of the present application, steel beams or steel columns arranged along the diagonal lines of the rectangle can also be arranged on the carrying frame 1 and the side edge frame 2, as long as the carrying frame 1 and the side edge frame 2 can form a generally rectangular frame structure, and these improvements should also be considered as the protection scope of the present application.

[0038] In an embodiment, referring to Fig. 1, the carrying frame 1 is composed of a plurality of steel beams or steel columns arranged in a crisscross manner, and the carrying frame 1 is generally arranged in a rectangular steel structure. A plurality of side edge frames 2 are arranged, each of which is connected to two adjacent carrying frames 1, and the side edge frame 2 is also composed of a plurality of steel beams or steel columns arranged in a crisscross manner, and is also generally arranged in a rectangular steel structure. A plurality of top connecting structures 6 are arranged, each of which is connected to two adjacent carrying frames 1.

[0039] In an embodiment, referring to Fig. 1, the carrying frame 1 is composed of a plurality of steel beams or steel columns arranged in a crisscross manner, and the carrying frame 1 is generally arranged in a rectangular steel structure. A plurality of side edge frames 2 are arranged, each of which is connected to two adjacent carrying frames 1, and the side edge frame 2 is also composed of a plurality of steel beams or steel columns arranged in a crisscross manner, and is also generally arranged in a rectangular steel structure. A plurality of top connecting structures 6 are arranged, each of which is connected to two adjacent carrying frames 1. Figures 4 to 6As shown, a first opening 33 is formed through the top wall of the battery slide rail 3 and communicates with the slide groove 31. The locking mechanism 4 includes a mounting seat 45 arranged on the top of the battery slide rail 3, and a second opening 451 is formed through the mounting seat 45 and communicates with the first opening 33. The pivot shaft 42 of the locking member 41 is parallel to the direction of the slot of the slide groove 31, and the pivot shaft 42 of the locking member 41 is arranged in the second opening 451. The locking member 41 is moved into or out of the slide groove 31 through the first opening 33 and the second opening 451.

[0040] Further, considering that the battery pack is stored on the battery slide rail 3, the locking member 41 divides the space of the slide groove 31 into two parts, one part is used to accommodate the rollers 8 of the battery pack, and the other part is generally not used to accommodate components related to the battery pack. Therefore, in order to maximize the space utilization of the slide groove 31, the locking member 41 and the mounting seat 45 are relatively close to the entrance and exit 32 on the battery slide rail 3, and are arranged as close to the entrance and exit 32 as possible.

[0041] In an embodiment, referring to Figure 1 As shown, a plurality of battery slide rails 3 arranged in the vertical direction are arranged on each bearing frame 1, and the storage space between the adjacent two bearing frames 1 can store a plurality of battery packs, thereby improving the space utilization of the storage space.

[0042] Further, when the left and right sides of a bearing frame 1 are both provided with battery slide rails 3, in order to avoid interference between the left and right battery slide rails 3, the left and right adjacent battery slide rails 3 can be arranged staggered up and down.

[0043] In an embodiment, referring to Figures 5 to 7 As shown, when the locking mechanism 4 is in the locked state, the cross section of the part of the locking member 41 located in the slide groove 31 is approximately triangular, one of the two oblique sides of the triangle extends to the upper right, and the other oblique side extends to the upper left.

[0044] Further, the top of the locking member 41 is provided with a guide portion 411, which is located on the side of the pivot shaft 42 away from the entrance and exit 32 in the horizontal direction. The guide portion 411 extends obliquely upward, and the side of the guide portion 411 close to the entrance and exit 32 is formed with a first guide surface 4111 extending obliquely upward. In the direction close to the pivot shaft 42, the distance between the first guide surface 4111 and the slide groove 31 gradually increases.

[0045] The first guide surface 4111 is used to cooperate with the unlocking pin 9 on the battery pack picking and placing device, and the unlocking pin 9 can move in the horizontal direction. The horizontal movement here can be understood as the unlocking pin 9 moving synchronously with the main structure of the battery pack picking and placing device. For example, the battery pack picking and placing device uses a battery-swapping trolley, and the battery-swapping trolley can move back and forth and left and right along the horizontal surface. When the battery-swapping trolley moves, the unlocking pin 9 moves synchronously horizontally with it. Alternatively, the horizontal movement here can be understood as the unlocking pin 9 moving relative to the main structure of the battery pack picking and placing device. For example, the battery pack picking and placing device uses a battery-swapping trolley, and the unlocking pin 9 is controlled by a driving element on the battery-swapping trolley (such as a cylinder, an electric cylinder, a hydraulic cylinder or a linear motor) to move horizontally relative to the main structure of the battery-swapping trolley.

[0046] When the locking mechanism 4 is in the locked state, the unlocking pin 9 moves horizontally toward the first guide surface 4111. After the unlocking pin 9 contacts the first guide surface 4111, relative sliding occurs between the unlocking pin 9 and the first guide surface 4111. However, since the unlocking pin 9 is restricted by the battery pack access device, the height of the unlocking pin 9 is fixed and it cannot move up and down. Therefore, the horizontal movement of the unlocking pin 9 is converted into the upward movement of the first guide surface 4111. The first guide surface 4111 is restricted by the pivot shaft 42, and its upward movement is converted into the upward pivoting of the locking member 41, thereby switching the locking mechanism 4 from the locked state to the unlocked state. Through the mutual cooperation between the first guide surface 4111 and the unlocking pin 9, the battery pack access device can quickly switch the locking mechanism 4 to the unlocked state when accessing the battery pack on the battery slide rail 3, thereby improving the access efficiency of the battery pack.

[0047] The longer the first guide surface 4111 is in the oblique direction, the greater the pivot angle of the locking member 41. However, as the length of the first guide surface 4111 increases, the length of the guide portion 411 in the oblique direction also increases, significantly reducing the structural strength of the guide portion 411. This significantly increases the probability of the guide portion 411 bending, deforming, and suffering fatigue damage under the action of the unlocking pin 9.

[0048] Therefore, in one embodiment, referring to Figure 7 As shown, in order to increase the length of the first guide surface 4111 in the inclined direction, increase the pivotable angle of the locking member 41, and ensure that the guide portion 411 has sufficient structural strength, a guide groove 412 is opened at the top of the locking member 41, and a second guide surface 4121 is formed in the guide groove 412. The second guide surface 4121 is connected to the first guide surface 4111 and is roughly located in the same plane as the first guide surface 4111, and the inclination directions of the two are roughly the same.

[0049] When the locking mechanism 4 switches from the locked state to the unlocked state, the unlocking pin 9 first contacts the first guide surface 4111 and slides relative to the first guide surface 4111, driving the locking member 41 to pivot. The unlocking pin 9 then enters the guide slot 412 and contacts the second guide surface 4121, sliding relative to the second guide surface 4121, driving the locking member 41 to continue pivoting. When the locking mechanism 4 is fully unlocked, the unlocking pin 9 is located within the guide slot 412.

[0050] After setting the guide groove 412 and the second guide surface 4121, without increasing the length of the guide portion 411, it is equivalent to increasing the length of the first guide surface 4111 in the inclined direction, which not only increases the pivotable angle of the locking member 41, but also ensures that the guide portion 411 has sufficient structural strength.

[0051] In one embodiment, referring to Figure 5 and Figure 6 As shown, the locking mechanism 4 also includes a fixing block 43 and an elastic member 44. The fixing block 43 is arranged on the top of the battery slide rail 3 and is located on the side of the locking member 41 away from the entrance and exit 32. The two sides of the elastic member 44 are respectively connected to the locking block and the fixing block 43.

[0052] When the locking mechanism 4 is in the locked state, the elastic member 44 is in a stretched state and is stretched substantially in the horizontal direction. The elastic force generated by the elastic member 44 provides a pulling force to the locking member 41 toward the fixing block 43, thereby fixing the position of the locking member 41 in the locked state.

[0053] When the locking mechanism 4 switches from the locked state to the unlocked state, the unlocking pin 9 contacts the guide portion 411, driving the locking member 41 to pivot upward, further stretching the elastic member 44. When the unlocking pin 9 is no longer in contact with the locking member 41, the elastic force of the elastic member 44 drives the locking member 41 to automatically return to its original position, stably maintaining the locked state.

[0054] Preferably, the elastic member 44 can be a spring, and a hook structure can be provided at the end of the spring to connect with the locking member 41 and the fixing block 43 through the hook structure.

[0055] In one embodiment, referring to Figure 3 As shown, the battery pack charging rack further includes a plurality of positioning members 5, which are disposed one-to-one on the plurality of battery rails 3. The positioning members 5 are located on the side of the battery rails 3 away from the side frame 2. The positioning members 5 are provided with positioning holes 51, which are used to cooperate with the positioning pins on the battery pack retrieval device to assist in positioning during the process of retrieval and placement of the battery pack.

[0056] Further, the positioning pin can move along a horizontal direction, and the horizontal movement of the positioning pin is similar to the horizontal movement of the unlocking pin 9, and can be synchronous horizontal movement with the main body structure of the battery pack taking and placing device, or horizontal movement relative to the main body structure of the battery swap vehicle.

[0057] In an embodiment, referring to Figure 1 As shown, in order to facilitate charging of the battery packs stored on the battery pack charging rack, the battery pack charging rack further comprises a connector 7 arranged on the side frame 2, the connector 7 being used for electrically connecting the battery pack and a charging source (such as mains), and charging the battery pack on the battery pack charging rack through the charging source. The connector 7 can float 5-10 mm in the up-down, front-back, and left-right directions, so as to ensure that the electrical connector of the battery pack can be stably and safely inserted into the connector 7, and avoid unnecessary damage to parts during the insertion process.

[0058] On the other hand, an embodiment of the present application also provides a mobile battery swap station, which comprises a battery swap vehicle and the battery pack charging rack in the above embodiment. The battery swap vehicle comprises a vehicle cabin, and the vehicle cabin is a side-opening vehicle cabin, and the side door on one side of the vehicle cabin can be controllably opened. The battery pack charging rack is arranged in the vehicle cabin, and a plurality of bearing frames 1 are arranged along the length direction of the vehicle cabin. The number of bearing frames 1 can be adaptively adjusted according to the size of the vehicle cabin. For example, when a light truck is selected as the battery swap vehicle, the length of the vehicle cabin is relatively short, and generally only two or three bearing frames 1 can be arranged. When a medium or large truck is selected as the battery swap vehicle, the number of bearing frames 1 can be adaptively increased, so that the battery swap vehicle can store more battery packs.
