Description

Technical Field

[0001] This application relates to a battery compartment, and more specifically to a battery compartment that is waterproof, dustproof, and has expandable capacity. Background Technology

[0002] With the rise of outdoor camping activities, consumer demand for outdoor camping products is also increasing. The most common outdoor camping products, such as electric trolleys, are usually equipped with battery packs for power supply to facilitate use in outdoor settings. To better protect the battery packs, they are also equipped with battery compartments to house them.

[0003] Common battery compartment designs include open battery housings on the trolley frame, secured with elastic straps. While this facilitates battery pack replacement and accommodates various sizes, the open housing and elastic straps offer limited protection, failing to provide adequate waterproofing or dustproofing. Another option is an openable, closed, rigid battery compartment on the trolley frame. While this provides better protection, its limited capacity restricts its compatibility to a certain size, potentially impacting the trolley's battery life in outdoor environments. Utility Model Content

[0004] The purpose of this application is to provide a battery compartment that is waterproof, dustproof, and has expandable capacity.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: A battery compartment is provided for mounting on a tool and housing a battery pack that powers the tool. The battery compartment includes a rigid back plate and a flexible housing fixedly connected thereto. The rigid back plate and the flexible housing define a receiving cavity to house the battery pack. The rigid back plate has a battery compartment mounting portion on one side for fixing the battery compartment to the tool, and a battery pack mounting portion on the other side for fixing the battery pack. The flexible housing has a switch zipper for opening or closing the battery compartment and an expansion zipper for changing the volume of the battery compartment. When the expansion zipper is open, the volume of the receiving cavity increases.

[0006] Furthermore, the rigid backplate includes a base plate and a cover plate that can be interlocked, wherein the battery compartment mounting portion is disposed on the side of the base plate away from the flexible package, and the battery compartment mounting portion is disposed on the side of the base plate close to the flexible package; the cover plate is provided with an opening to expose the battery pack mounting portion.

[0007] As another preferred embodiment, a cavity for accommodating electrical components is formed between the base plate and the cover plate.

[0008] As another preferred embodiment, the battery pack mounting section includes a groove and a plug-in terminal that can be mechanically and electrically connected to the battery pack.

[0009] As another preferred embodiment, the battery compartment further includes a safety key, and the cover plate has an insertion hole for inserting the safety key.

[0010] Furthermore, the flexible package includes a package connecting portion that can be fixedly connected to the rigid back plate, and the package connecting portion has an edge portion extending toward the interior of the receiving cavity; the edge portion can be fixed between the bottom plate and the cover plate as the bottom plate and the cover plate are engaged.

[0011] Furthermore, the flexible package also includes a main package and a package closure portion, the package closure portion being able to close the receiving cavity in the horizontal direction, the switch zipper being disposed between the package connecting portion and the main package, and the expansion zipper being disposed between the main package and the package closure portion.

[0012] Furthermore, when the battery compartment is in the first state, the expansion zipper is not open, and the thickness of the main body in the horizontal direction is L1; when the battery compartment is in the second state, the expansion zipper is open, and the thickness of the main body in the horizontal direction is L2, where L2 > L1.

[0013] As another preferred embodiment, the battery compartment mounting portion is a mounting protrusion extending from the base plate toward the side away from the flexible package, and the mounting protrusion can be fixedly connected to the tool by fasteners.

[0014] Furthermore, the mounting protrusion is approximately L-shaped, including a long side extending vertically and a short side extending forward and backward and approximately perpendicular to the long side; the tool is a trolley, and the battery compartment can be mounted on the frame of either side of the trolley. The frame of either side includes two adjacent horizontal bars and vertical bars, and the long side and the short side can be fixedly connected to the horizontal bars and the vertical bars respectively through the fasteners.

[0015] Compared with the prior art, the beneficial effects of this application are as follows: The battery compartment provided in this application includes a rigid backplate and a flexible housing. The combination of these two components not only ensures sufficient installation strength between the battery compartment and the battery pack, as well as the tools requiring power, but also allows for variations in the battery compartment's volume. By incorporating expansion zippers on the flexible housing, the battery compartment's volume can be adjusted to accommodate battery packs of different thicknesses and sizes, improving its adaptability, expanding its application scenarios, extending the tool's battery life, meeting the battery life requirements of different scenarios and tools, and enhancing the user experience.

[0022] This application provides a battery compartment 1, see [link]. Figures 1 to 5 The battery compartment 1 is used to mount a tool, such as a trolley 3, and to house a battery pack 2 that powers the tool. The battery compartment 1 includes a rigid back plate 10 and a flexible housing 20 fixedly connected thereto. The rigid back plate 10 and the flexible housing 20 define a receiving cavity 30 to house the battery pack 2. One side of the rigid back plate 10 is provided with a battery compartment mounting part 11 for fixing the battery compartment 1 to the tool, and the other side of the rigid back plate 10 is provided with a battery pack mounting part 12 for fixing the battery pack 2. The flexible housing 20 is provided with a switch zipper 22 for opening or closing the battery compartment 1 and an expansion zipper 24 for changing the volume of the battery compartment 1. When the expansion zipper 24 is opened, the volume of the receiving cavity 30 increases.

[0023] The battery compartment 1 disclosed in this application has a rigid back plate 10 that ensures a stable connection between the battery compartment 1 and the battery pack 2, as well as the tool requiring power. Simultaneously, the flexible housing 20 allows for flexible volume changes; the volume of the receiving cavity 30 can be altered via the expansion zipper 24 to accommodate battery packs of different thicknesses and sizes, resulting in greater adaptability, expanding the application scenarios of the battery compartment 1, and extending the tool's battery life. In this embodiment, the rigid back plate 10 can be made of a rigid material with a certain degree of hardness, such as plastic, which satisfies installation strength requirements while maintaining low cost. The flexible housing 20 can be made of Oxford cloth, which not only allows for the installation of the zipper 22 and the expansion zipper 24 but also provides a degree of waterproofing.

[0024] Specifically, see Figures 1 to 6The rigid backplate 10 includes a base plate 13 and a cover plate 14 that can be interlocked. A battery compartment mounting portion 11 is provided on the side of the base plate 13 away from the flexible housing 20, and a battery pack mounting portion 12 is provided on the side closer to the flexible housing 20. The battery compartment mounting portion 11 can be connected to a tool such as a trolley 3 via screws or other fasteners to secure the battery compartment 1 to the tool. The battery pack mounting portion 12 is provided with a plug-in terminal 121 and a sliding groove 122, enabling mechanical and electrical connection with the battery pack 2. An opening 141 is provided on the cover plate 14 at a position corresponding to the battery pack mounting portion 12 to expose the battery pack mounting portion 12, thereby facilitating the installation and removal of the battery pack 2.

[0025] As one implementation method, in this embodiment, see Figure 6 The battery compartment mounting part 11 is configured as a generally L-shaped mounting protrusion 111 extending from the base plate 13 toward the side away from the flexible housing 20. The mounting protrusion 111 includes a long side 1111 extending vertically and a short side 1112 extending in the front-rear direction and approximately perpendicular to the long side 1111. Taking the trolley 3 as an example, the battery compartment 1 can be mounted on the frame 31 on either side of the trolley. Specifically, in this embodiment, the battery compartment 1 can be fixed at the intersection of two adjacent horizontal bars 311 and vertical bars 312 of the frame 31. The horizontal bars 311 and vertical bars 312 are respectively fixedly connected to the long side 1111 and short side 1112 of the L-shaped mounting protrusion by screws or other fasteners, thereby achieving a fixed installation of the battery compartment 1 and the trolley. It is understood that in other embodiments, the battery compartment mounting part 11 can also be configured with other shapes, as long as it can satisfy the need for fixing the battery compartment mounting part 11 to the tool requiring power.

[0026] Further, see Figure 5 In this embodiment, a cavity 18 is formed between the interlocking base plate 13 and cover plate 14 to accommodate the circuit board 16 and other electrical components. Preferably, the shape of the cavity 18 is adapted to the shape of the battery compartment mounting portion 11, i.e., the mounting protrusion 111, that is, it is approximately L-shaped. In this way, without increasing the thickness of the battery compartment 1, as much space as possible can be provided for the storage and layout of the circuit board 16 and other electrical components, so as to make full use of the space.

[0027] Further preferably, in this embodiment, see Figure 5 The battery pack mounting portion 12 is disposed adjacent to the cavity 18. Specifically, the lower portion 142 of the cover plate 14 protrudes in a direction away from the base plate 13, wherein the lower portion 142 includes an opening 141 formed on one side to expose the battery pack mounting portion 12, and a closure portion 143 formed on the other side to close the cavity 18.

[0028] In this embodiment, the battery compartment 1 is also provided with a safety key 17. An insertion hole 171 is formed on the closed portion 143 of the cover plate 14, which allows the safety key 17 to be inserted. After the battery pack 2 is connected to the battery compartment 1 via the battery pack mounting portion 12, the safety key 17 is inserted to enable the battery pack 2 to supply power to the tool. When it is necessary to stop the power supply to the battery pack 2, the safety key 17 can be removed, thereby improving the safe usability of the battery compartment 1 and the battery pack 2.

[0029] See Figures 1 to 5 The flexible package 20 includes a package connecting portion 21, a switch zipper 22, a main package 23, an expansion zipper 24, and a package closing portion 25 arranged sequentially along the horizontal direction. The package connecting portion 21 is used for fixed connection to the rigid back plate 10, the package closing portion 25 is used to close the receiving cavity 30 along the horizontal direction, and the switch zipper 22, the main package 23, and the expansion zipper 24 are used to close the receiving cavity 30 along the vertical and horizontal directions and the front-back direction. Preferably, in this embodiment, the flexible package 20 is integrally formed.

[0030] Specifically, in this embodiment, the package connecting portion 21 is provided with an edge portion 211 extending toward the interior of the receiving cavity 30, and the edge portion 211 can be fixed between the bottom plate 13 and the cover plate 14. That is, when the bottom plate 13 and the cover plate 14 are engaged with each other, the edge portion 211 is also fixed between the two, thereby realizing the fixed connection between the flexible package 20 and the rigid back plate 10. Preferably, the distance by which the edge portion 211 extends toward the interior of the receiving cavity 30 is such that it does not obstruct the arrangement of the battery pack mounting portion 12, the circuit board 16, the safety key 17 and other electrical components located between the bottom plate 13 and the cover plate 14.

[0031] See Figures 1 to 5 One side of the main body 23 is provided with a switch zipper 22 that can open or close the battery compartment 1, and the other side is provided with an expansion zipper 24 that can expand the capacity of the battery compartment 1. When the expansion zipper 24 is opened, the volume of the receiving cavity 30 increases. Specifically, see Figure 1 and Figure 3 When the battery compartment 1 is in the first state, the expansion zipper 24 is not open, and the thickness of the main body 23 in the horizontal direction is L1; see [link / reference]. Figure 2 and Figure 4 When the battery compartment 1 is in the second state, the expansion zipper 24 is open, and the thickness of the main body 23 in the horizontal direction is L2, where L2 > L1. That is, when the expansion zipper 24 is open, i.e., when the battery compartment 1 is in the second state, the receiving cavity 30 can accommodate a larger battery pack 2'. In the field of battery packs, a larger size usually means a larger capacity and longer battery life. The design of the expansion zipper 24 allows the battery compartment 1 to accommodate battery packs of various sizes, meaning it can accommodate battery packs of various capacities, meeting different user battery life requirements and usage scenarios.

[0032] Further preferably, in this embodiment, see Figures 1 to 4 The switch zipper 22 is located above the battery compartment 1. Thus, when the switch zipper 22 is opened, the battery compartment 1 can be opened from bottom to top. At this time, the user can insert the battery pack 2 from top to bottom into the battery pack mounting part 12 to install the battery pack 2, or slide the battery pack 2 out from bottom to top on the battery pack mounting part 12. It is understood that in other embodiments, the switch zipper 22 can also be located in other directions of the battery compartment 1, and the battery compartment 1 can also be opened from other directions, as long as the battery pack 2 is exposed to facilitate its installation and removal.

[0033] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
