Description

Technical Field

[0001] This utility model belongs to the field of battery casing technology, and particularly relates to a cell casing and battery pack. Background Technology

[0002] Currently, motorcycle battery packs typically use multiple cylindrical cells assembled into modules, which are then fixed and protected by a casing structure. In existing technology, the cell casing often adopts a split design, consisting of an upper casing and a lower base plate. The common assembly method is to fix the cell to the lower base plate, slide the upper casing in from the side, and then secure it with screws or other fasteners.

[0003] This type of lateral mounting method has significant structural defects: First, lateral mounting requires the design of complex guide rails and positioning structures to ensure alignment during assembly, which not only increases the complexity of the mold and production costs but also limits the freedom of structural design for the housing. Second, lateral mounting requires openings at the bottom and sides of the upper housing; the bottom opening accommodates the lower base plate, and the side opening is for sliding into the rail. This double-opening design not only compromises the structural integrity of the housing and affects its overall rigidity but also requires additional sealing structures, increasing manufacturing costs and assembly complexity. Furthermore, the existing housing has significant shortcomings in terms of maintenance; connecting battery cells or performing maintenance typically requires disassembling the entire upper housing, thus increasing maintenance time and workload. Summary of the Invention

[0004] This utility model provides a cell housing and a battery pack. The cell housing is easy to assemble and facilitates the later maintenance of the battery pack, thereby reducing the maintenance time and workload of the battery pack.

[0005] The present invention provides a battery cell housing, comprising:

[0006] A base plate assembly includes a base plate and a lower bracket disposed on the base plate for mounting battery cells;

[0007] The housing has a cavity for housing the battery cell and an open end. The inner contour of the housing matches the outer contour of the lower support. The open end of the housing engages with the base plate in a direction perpendicular to the surface of the base plate and is detachably and fixedly connected. The cavity is used to house the battery cell.

[0008] An electrical appliance bracket is disposed on one side of the lower bracket and vertically fixed to the surface of the base plate;

[0009] The housing is provided with an inspection port and a wiring port, with the wiring port located on one side of the inspection port, and the electrical bracket inside the housing is exposed through the inspection port.

[0010] In one embodiment of the present invention, the outer shell includes a top plate and a surrounding plate arranged around the top plate. The inspection port is provided on the surrounding plate at one end of the outer shell. The top plate and the bottom plate are arranged opposite to each other. The battery cell housing formed by the outer shell and the bottom plate being engaged and installed together is generally rectangular.

[0011] In one embodiment of the present invention, the wiring port is disposed on the side panel of the panel where the inspection port is located, and the panel where the wiring port is located is disposed at an obtuse angle to the panel where the inspection port is located, so that the wiring port is tilted towards the electrical bracket.

[0013] In one embodiment of the present invention, the electrical appliance bracket includes a first plate, a second plate, and a bent plate;

[0014] The first plate and the second plate are vertically connected as a whole, the first plate is perpendicular to the base plate, and the second plate is attached to the base plate;

[0015] The first end of the bent plate is fixedly connected to the first plate, and the second end of the bent plate away from the first end is bent in a direction parallel to the first plate and spaced apart from the first plate. The second end of the bent plate is used to install an electrical mounting plate.

[0016] In one embodiment of the present invention, the lower bracket has a plurality of recesses on its edge, and the inner side of the outer shell has a plurality of protrusions that correspond to and fit the recesses. The outer shell is limited to the lower bracket through the protrusions.

[0017] Furthermore, the protrusion is provided with mounting holes for mounting and connecting with the base plate in the direction facing the base plate.

[0018] In one embodiment of this utility model, both the base plate and the outer shell are provided with hooks for installing the battery cell housing.

[0019] In one embodiment of this utility model, both the outer shell and the base plate are made of aluminum.

[0020] The present invention provides a battery pack, including the aforementioned cell housing.

[0021] In one embodiment of the present invention, the battery pack further includes an upper bracket and a plurality of battery cells disposed between the upper bracket and the lower bracket;

[0022] The upper support is provided with a first slot array facing the lower support; the lower support is provided with a second slot array facing the upper support.

In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the present invention.

[0038] like Figure 1-3 As shown, this utility model provides a battery cell housing, including a base plate assembly 1, a housing 2, and an electrical support 3;

[0039] The base plate assembly 1 includes a base plate 11 and a lower bracket 12 disposed on the base plate 11 for mounting battery cells; the outer shell 2 has a cavity for receiving battery cells and an open end, the inner contour of the outer shell 2 matches the outer contour of the lower bracket 12; the open end of the outer shell 2 engages with the base plate 11 in a direction perpendicular to the plate surface of the base plate 11 and is detachably fixedly connected, the cavity is used to receive battery cells; the electrical support 3 is disposed on one side of the lower bracket 12 and is vertically fixed to the plate surface of the base plate 11;

[0040] The outer casing 2 is provided with an inspection port 23 and a wiring port 24. The wiring port 24 is located on one side of the inspection port 23, and the electrical bracket 3 inside the outer casing 2 is exposed through the inspection port 23.

[0041] It should be noted that the base plate 11, as the basic component for battery cell installation, can adopt a flat structure or a structure with mounting grooves. The shape of the mounting grooves is adapted to the outer contour of the battery cell. Preferably, the base plate 11 is made of metal or engineering plastic. The outer shell 2 has a cavity for accommodating cylindrical battery cells and an open end. The shape of the cavity is adapted to the arrangement of the battery cells and can be set as a rectangular cavity or a cylindrical cavity. The open end of the outer shell 2 engages with the base plate 11 in a direction perpendicular to the surface of the base plate 11. This engagement can be achieved through a concave-convex fit structure, a snap-fit ​​connection structure, or an interference fit, such as the engagement of a guide groove and a guide bar or the engagement of a hook and a slot. Alternatively, the outer shell 2 and the base plate 11 can be engaged and then connected by screws or a quick-release mechanism for detachable fixing. The electrical bracket 3 is disposed on one side of the base plate 11 and vertically fixed to the surface of the base plate 11. The electrical bracket 3 can be fixed to the base plate 11 by welding, riveting, or fasteners and is used to install electrical connection components. The housing 2 is provided with an inspection port 23 and a wiring port 24. The wiring port 24 is located on one side of the inspection port 23. The inspection port 23 can be configured as a rectangular opening or a circular opening. The wiring port 24 can be configured as a cable through hole or a connector installation port. The electrical bracket 3 inside the housing 2 is exposed through the inspection port 23, which facilitates electrical connection and maintenance operations.

[0042] This invention achieves initial positioning and assembly of the outer shell 2 and the base plate 11 through a vertical snap-fit ​​method. During assembly, simply align the outer shell 2 vertically with the base plate 11 and press it down. Positioning is achieved through the cooperation of the outer shell 2 and the lower bracket 12, and then final fixation is achieved using screws and other fasteners. This assembly method avoids the complex guiding structure required for lateral installation, simplifies the assembly process, and improves production efficiency. The inclusion of the inspection port 23 and the wiring port 24 allows for cell wiring connections and subsequent maintenance without disassembling the entire outer shell 2. The electrical bracket 3 and connecting lines can be directly operated through the cooperation of the inspection port 23 and the wiring port 24, significantly improving maintenance convenience. The design of the electrical bracket 3 being vertically fixed to the base plate 11 and exposed through the inspection port 23 optimizes the internal space layout and improves space utilization, making it particularly suitable for space-constrained motorcycle battery pack applications. The cell shell structure of this invention has the advantages of convenient assembly, easy maintenance, and compact structure, effectively solving the problems of complex assembly and difficult maintenance existing in the prior art.

[0043] like Figure 2-3 As shown, as an optional embodiment of this case, the outer shell 2 includes a top plate 25 and a surrounding plate 26 surrounding the top plate 25. The inspection port 23 is provided on the surrounding plate 26 at one end of the outer shell 2. The top plate 25 and the bottom plate 11 are opposite to each other. The outer shell 2 and the bottom plate 11 are engaged and installed to form a battery cell housing, which is generally rectangular.

[0044] It should be noted that the outer casing 2 adopts a box-like structure composed of a top plate 25 and a surrounding plate 26. The top plate 25 can be a flat plate or a plate structure with reinforcing ribs. The surrounding plate 26 and the top plate 25 can be integrally formed or welded separately. The surrounding plate 26 is set around the top plate 25 to form a closed frame structure. The access port 23 is set on the surrounding plate 26 at one end of the outer casing 2. This end surrounding plate 26 can be a front surrounding plate 26 or a side surrounding plate 26. The top plate 25 and the bottom plate 11 are arranged in a parallel and opposing manner, so that the battery cell housing formed after the outer casing 2 and the bottom plate 11 are engaged and installed has a regular cuboid shape. This structure not only facilitates space utilization but also makes it easy to arrange and install the battery pack in the motorcycle. The cuboid structure can be achieved through right-angle transitions or rounded corner transitions, with rounded corner transitions preferred to enhance structural strength. The overall size of the outer casing 2 can be adjusted according to the number and arrangement of the battery cells. The height of the surrounding plate 26 is adapted to the height of the battery cells to ensure that the battery cells are adequately protected. This structural design optimizes space utilization through its regular rectangular shape, allowing for optimal battery pack placement within the limited space of a motorcycle. The access port 23, located on one end panel 26, facilitates maintenance operations from a specific direction, improving operational convenience.

[0045] like Figure 1-3As shown, in an optional embodiment of this case, the wiring port 24 is disposed on the side panel 26 of the panel 26 where the inspection port 23 is located. The panel 26 where the wiring port 24 is located is disposed at an obtuse angle to the panel 26 where the inspection port 23 is located, so that the wiring port 24 is tilted towards the electrical bracket 3.

[0046] It should be noted that the connection port 24 is located on the adjacent panel 26 of the panel 26 where the access port 23 is located, specifically on the side panel 26 that forms an obtuse angle with the panel 26 where the access port 23 is located. This arrangement ensures that the opening direction of the connection port 24 corresponds optimally to the electrical bracket 3. The central axis of the connection port 24 forms an acute or obtuse angle with the mounting plane of the electrical bracket 3, preferably with an inclination angle between 45 and 135 degrees. This inclination allows the connection port 24 to directly face the wiring area of ​​the electrical bracket 3, facilitating cable laying and connection operations. The connection port 24 can be designed as a circular, elliptical, or rectangular opening, with chamfered or protective sleeves at the edges to prevent cable abrasion. The size of the connection port 24 is determined according to the connector type and the number of cables, and can be a single large-diameter interface or an array of multiple small-diameter interfaces. The inclination of the connection port 24 towards the electrical bracket 3 ensures that the cable entry direction is consistent with the wiring operation direction, improving wiring efficiency and quality. The arrangement of the side panel 26 avoids creating multiple openings simultaneously on the inspection port 23 panel 26, thus maintaining the structural integrity of the panel 26. This arrangement satisfies functional requirements while ensuring the structural strength of the outer shell 2.

[0047] like Figure 1-3 As shown, in an optional embodiment of this case, the outer shell 2 is provided with a groove area 27, the inspection port 23 is located in the groove area 27, and an inspection plate 5 is provided at the groove area 27. The inspection plate 5 is configured to match at least a portion of the outline dimensions of the groove area 27.

[0048] It should be noted that the recessed area 27 is located on the outer surface of the enclosure plate 26 of the outer shell 2, and is formed by stamping or milling to create an inwardly recessed area. The depth of the recess can be designed according to structural requirements, preferably 0.3 to 0.7 times the thickness of the enclosure plate 26. The access port 23 is located in the center of the surface where the recessed area 27 is located, and its size is slightly smaller than that of the recessed area 27. The access plate 5 is designed to match at least part of the contour dimensions of the recessed area 27, and can be installed on the recessed area 27 by means of hinge connection, slide rail installation, snap-fit ​​fixing or fastener fixing. The at least partial contour matching facilitates the installation and positioning of the access plate 5 to a certain extent. A sealing ring or waterproof strip can be provided between the access plate 5 and the recessed area 27 to ensure good sealing performance. A handle or opening groove can be provided on the surface of the access plate 5 for easy opening by the operator. Mounting screw holes or snap-fit ​​seats can be provided around the recessed area 27 for fixing the access plate 5.

[0049] This structure provides additional installation space through the recessed area 27, allowing the access panel 5 to be installed flush with the surface of the housing 2, maintaining the overall aesthetics of the housing 2. The recessed area 27 also serves a protective function, preventing the access panel 5 from being directly exposed to the outside and damaged by impacts. The removable design of the access panel 5 allows maintenance personnel to quickly access internal components, improving maintenance efficiency. The addition of a sealed structure further enhances the battery pack's dust and water resistance, making it particularly suitable for the use of motorcycles in complex environments.

[0050] like Figure 4 As shown, in an optional embodiment of this case, the electrical bracket 3 includes a first plate 31, a second plate 32, and a bent plate 33; the first plate 31 and the second plate 32 are vertically connected as a whole, the first plate 31 is perpendicular to the base plate 11, and the second plate 32 is fitted to the base plate 11; the first end of the bent plate 33 is fixedly connected to the first plate 31, and the second end of the bent plate 33 away from the first end is bent in a direction parallel to the first plate 31 and spaced apart from the first plate 31; the second end of the bent plate 33 is used to install the electrical mounting plate 6.

[0051] It should be noted that the electrical bracket 3 adopts a multi-plate combination structure. The first plate 31 is a vertical plate, which is set perpendicularly to the base plate 11 and fixed by welding or bolts. The second plate 32 is a horizontal base plate 11, which is perpendicularly connected to the first plate 31 to form an L-shaped base. The second plate 32 is fixedly attached to the surface of the base plate 11. One end of the bent plate 33 is fixedly connected to the first plate 31, and the other end is bent in a direction parallel to the first plate 31 to form a cantilever structure parallel to the first plate 31. An appropriate gap is maintained between the bent plate 33 and the first plate 31 to form an installation space. The second end of the bent plate 33 is provided with a mounting hole or slot for fixing the electrical mounting plate 6. The electrical mounting plate 6 can install electrical components such as connectors and fuses. The bending angle of the bent plate 33 is preferably 90 to 135 degrees. In this case, the L-shaped base formed by the first plate 31 and the second plate 32 ensures the rigidity of the overall structure, and the gap between the bent plate 33 and the first plate 31 forms a cable wiring channel, which is conducive to the neat arrangement and maintenance of cables. The dedicated mounting end of the electrical mounting plate 6 allows electrical components to be arranged in an orderly manner, improving connection reliability and ease of maintenance.

[0052] like Figure 3 , 6 and Figure 7 As shown, in an optional embodiment of this case, the lower bracket 12 is provided with a plurality of recesses 121 on its edge, and the inner side of the outer shell 2 is provided with a plurality of protrusions 28 that correspond to and are adapted to the recesses 121. The outer shell 2 is limited to the lower bracket 12 through the protrusions 28; and the protrusions 28 are provided with mounting holes 281 for mounting and connecting with the base plate 11 in the direction facing the base plate 11.

[0053] It should be noted that multiple recesses 121 are evenly distributed along the edge of the lower bracket 12. The shape of the recesses 121 can be an arc-shaped groove, a rectangular pit, or a V-shaped notch. A protrusion 28 is provided at a corresponding position on the inner side of the outer shell 2. The shape of the protrusion 28 matches the recesses 121, forming a precise positioning fit. The fit between the protrusion 28 and the recesses 121 adopts a transition fit or a slight interference fit to ensure guiding and limiting functions during assembly. A mounting hole 281 is provided at the bottom of the protrusion 28 facing the base plate 11. The mounting hole 281 can be a threaded hole or a smooth hole, used for connection and fixation to the base plate 11 by bolts 123 or by interference fit with pins. The number of recesses 121 and protrusions 28 is determined according to the bracket size, typically 3 to 15 sets of mating pairs are evenly distributed around the bracket. The arrangement of the mating pairs adopts an asymmetrical distribution to ensure the uniqueness and correctness of the assembly. This mating structure achieves rapid alignment of the outer shell 2 and the lower bracket 12 through the precise positioning of the concave-convex pairs, simplifying the assembly process. The distribution of multiple mating pairs ensures connection stability and uniform force distribution. The mounting holes 281 unify the fixed connection point and the positioning point, reducing the number of parts and assembly steps. The asymmetrical distribution design prevents incorrect assembly and improves assembly reliability. This structural design is particularly suitable for mass production, significantly improving production efficiency and product consistency.

[0054] like Figure 2 As shown, as an optional embodiment of this case, both the base plate 11 and the outer shell 2 are provided with hooks 111 for installing the battery cell housing, so as to facilitate the lifting and transportation of the base plate 11 and the outer shell 2, which helps to reduce the labor intensity of manual handling.

[0055] As an optional embodiment of this case, both the outer shell 2 and the base plate 11 are made of aluminum.

[0056] It should be noted that aluminum alloys can be selected as the aluminum material, offering good strength and machinability. The sheet thickness is determined based on structural strength requirements, typically ranging from 1.5 to 3.0 mm. The aluminum surface undergoes anodizing to improve corrosion resistance and surface hardness. The material's high thermal conductivity ensures excellent heat dissipation. Aluminum's low density enables lightweight design. Aluminum can be manufactured using extrusion, stamping, or die-casting processes to meet diverse structural needs. The application of aluminum significantly improves the heat dissipation of the casing, facilitating heat dissipation during battery cell operation and extending battery life. The lightweight design reduces overall weight, making it particularly suitable for motorcycles with their weight-sensitive requirements. Good machinability allows for complex structures, increasing design freedom. Corrosion resistance ensures the product's lifespan in harsh environments. The selection of environmentally friendly materials aligns with sustainable development principles.

[0057] This utility model provides a battery pack, including the aforementioned cell housing.

[0058] It should be noted that the overall structure of the battery pack is supported by the cell housing, which houses the cell assembly and electrical connection system. The cell housing provides mechanical protection, heat dissipation channels, and maintenance interfaces for the battery pack, ensuring its reliability and safety in the motorcycle operating environment. The external dimensions of the battery pack can be adjusted according to specific application requirements, with a compact design preferred to fit the limited installation space of a motorcycle. The battery pack may also include auxiliary systems such as temperature sensors and voltage detection modules, which can be integrated into the electrical bracket 3 and maintained and adjusted through the access port 23.

[0059] like Figure 7-8 As shown, as an optional embodiment of this case, it also includes an upper bracket 7 and a plurality of battery cells 4 disposed between the upper bracket 7 and the lower bracket 12;

[0060] The upper support 7 is provided with a first slot array 71 facing the lower support 12; the lower support 12 is provided with a second slot array 122 facing the upper support 7. The slots of the first slot array 71 and the second slot array 122 correspond one-to-one and together limit the position of the battery cell 4. Adjacent battery cells 4 are connected in series and / or in parallel through electrical connecting pieces 8. The upper support 7, the lower support 12 and the battery cell 4 are housed in the cavity of the outer shell 2.

[0061] It should be noted that the upper support 7 and lower support 12 are made of insulating materials, such as engineering plastics or composite materials, to ensure electrical insulation between the battery cell 4 and the casing, and between the battery cell 4 and the casing. The slot shapes of the first slot array 71 and the second slot array 122 are adapted to the outer contour of the battery cell 4, and can be circular, hexagonal, or other polygonal hole types. The slot array is arranged in a matrix, and the row spacing and column spacing are determined according to the size of the battery cell 4 and the heat dissipation requirements. The inner wall of the slot can be provided with elastic material to provide buffer protection for the battery cell 4. The electrical connecting piece 8 is made of a metal material with good conductivity, such as copper or aluminum, and is connected to the electrodes of the battery cell 4 by welding, riveting, or pressing. The shape of the connecting piece is designed according to the arrangement of the battery cell 4, and can realize series, parallel, or series-parallel hybrid connections. During cell 4 installation, the lower end of cell 4 is first inserted into the slot of the lower bracket 12, and then the upper bracket 7 is installed so that the upper end of cell 4 enters the corresponding slot, forming a bidirectional limiting structure. This ensures the precise positioning and reliable fixation of cell 4 within the housing, effectively preventing displacement and damage under vibration. The symmetrical distribution of the slot array ensures the neat arrangement of cell 4, which is beneficial for uniform heat dissipation and standardized electrical connection. The rational design of the electrical connection piece 8 enables the battery pack to provide the required voltage and capacity output, meeting the needs of different electrical devices. This design, through the coordinated limiting of the upper bracket 7 and the lower bracket 12, provides a stable installation environment for cell 4, improving the shock resistance and reliability of the battery pack. The precise alignment of the slot array ensures the accuracy and consistency of cell 4 installation, facilitating automated production. The standardized design of the electrical connection piece 8 simplifies the electrical connection process, improving connection reliability and production efficiency. The overall structural design fully considers the needs of large-scale production, possessing good manufacturability and economy.
