Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic equipment technology, and in particular to a battery compartment and electronic equipment. Background Technology
[0002] In existing technology, the battery compartment includes a housing and conductive springs mounted on the housing. The conductive springs contact the battery electrodes to achieve conductivity. One type of conductive spring uses a single elastic arm structure, which has poor elasticity and is prone to deformation during assembly with the housing, leading to poor contact with the battery and causing power loss. Another type of conductive spring uses a multi-folding method to improve elasticity, solving the problem of poor contact with the battery caused by deformation during installation. However, its structure is complex and difficult to manufacture, resulting in inaccurate control of the amount of interference with the battery. Too loose an interference leads to poor contact, while too tight an interference affects the user experience. Utility Model Content

[0037] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0040] like Figures 1-12 As shown, this embodiment provides a battery compartment, including a circuit board 100 and a first spring contact assembly 200 and a second spring contact assembly 300 disposed on the circuit board 100. Both the first spring contact assembly 200 and the second spring contact assembly 300 include a spring contact seat 1 and a conductive spring contact 2. The spring contact seat 1 is provided with a boss 11 and a first buckle 12. The top of the boss 11 is provided with an end cap 13, and the side of the boss 11 is a limiting plane 111. The conductive spring 2 has a limiting hole, and the boss 11 can pass through the limiting hole, so that the limiting plane 111 is limited to the hole wall of the limiting hole, and the conductive spring 2 is limited between the end cap 13 and the spring seat 1. The conductive spring 2 is snapped into the first buckle 12. The limiting plane 111 and the first buckle 12 realize the limitation of the conductive spring 2 in its planar extension direction. The end cap 13, the spring seat 1, and the first buckle 12 realize the limitation of the conductive spring 2 in its vertical direction (the installation direction of the conductive spring 2 and the spring seat 1), thereby realizing the installation and fixation between the conductive spring 2 and the spring seat 1.
[0041] The conductive spring 2 is electrically connected to the circuit board 100. The conductive spring 2 of the first spring assembly 200 and the conductive spring 2 of the second spring assembly 300 are arranged facing each other to abut against the two electrodes of the battery 800, respectively. Since both the first spring assembly 200 and the second spring assembly 300 are located on the circuit board 100, and the conductive spring 2 of the first spring assembly 200 and the conductive spring 2 of the second spring assembly 300 are arranged facing each other to abut against the two electrodes of the battery 800, and both the conductive spring 2 of the first spring assembly 200 and the conductive spring 2 of the second spring assembly 300 are electrically connected to the circuit board 100, a conductive connection between the circuit board 100 and the battery 800 is achieved.
[0042] In one embodiment, the limiting hole is an elongated opening 21, with a large hole end 211 and a small hole end 212 at both ends. The opening area of the large hole end 211 is larger than that of the small hole end 212. The end cap 13 can pass through the large hole end 211, and the boss 11 can slide from the large hole end 211 to the small hole end 212. The limiting plane 111 is limited to the hole wall of the small hole end 212, so that the conductive spring piece 2 is limited between the end cap 13 and the spring piece seat 1. When the boss 11 is located at the small hole end 212, the conductive spring piece 2 can be engaged with the first buckle 12. After the spring piece seat 1 and the conductive spring piece 2 are assembled, the small hole end 212 is located between the large hole end 211 and the first buckle 12.
[0043] During assembly, the end cap 13 of the spring holder 1 passes through the large hole end 211 of the opening 21 of the conductive spring 2, with the boss 11 located inside the opening 21. The boss 11 then slides from the large hole end 211 to the small hole end 212. Since the limiting plane 111 of the boss 11 is located on the hole wall of the small hole end 212, the end cap 13 is prevented from passing through the small hole end 212, thus limiting the conductive spring 2 within the end cap 13 and the spring holder 1, achieving the limiting of the conductive spring 2 and the spring holder 1 in the installation direction. Finally, the conductive spring 2 is engaged with the first latch 12 to prevent the boss 11 from sliding from the small hole end 212 to the large hole end 211 in case of accidental movement, thus limiting the relative movement or rotation between the conductive spring 2 and the spring holder 1, thereby achieving the fixation between the conductive spring 2 and the spring holder 1. By limiting the shape of the limiting hole, the assembly between the spring holder 1 and the conductive spring 2 is facilitated.
[0044] The simple structure of the spring holder 1 and the conductive spring 2 reduces the processing difficulty and avoids the interference with the battery 800 being too loose or too tight due to inaccurate control. In addition, the two are easy to install and can prevent the conductive spring 2 from deforming during the assembly process, so as to ensure good contact with the battery 800.
[0045] The first contact spring assembly 200 includes two conductive contacts 2, each used to contact the electrodes of two batteries 800 with opposite electrode polarities. The second contact spring assembly 300 includes one conductive contact 2, which simultaneously contacts the electrodes of both batteries 800 with opposite electrode polarities, thus connecting the two batteries 800 in series via the first contact spring assembly 200 and the second contact spring assembly 300. By configuring the first contact spring assembly 200 with two independent conductive contacts 2 and the second contact spring assembly 300 with one conductive contact 2, the series connection of the two batteries 800 can be achieved to meet usage requirements.
[0046] Furthermore, the conductive spring 2 is provided with at least two openings 21, and the spring seat 1 is provided with at least two bosses 11 with end faces. At least two bosses 11 with end caps 13 and at least two openings 21 are connected in a one-to-one correspondence. The conductive spring 2 is snapped in place by at least two first buckles 12, thereby improving the connection reliability.
[0047] The first spring assembly 200 has two conductive springs 2, one with a first fixing part 22 and the other with a first elastic part 23. The second spring assembly 300 has conductive springs 2 with a second fixing part 24 and a second elastic part 25. The first fixing part 22 and the second elastic part 25 are arranged opposite to each other for clamping one battery 800, and the first elastic part 23 and the second fixing part 24 are arranged opposite to each other for clamping another battery 800. The first elastic part 23 and the second elastic part 25 can be elastic sheets or springs, etc., and are not limited. Exemplarily, the first fixing part 22 and the second fixing part 24 are both used to abut against the positive terminal of the battery 800, and the first elastic part 23 and the second elastic part 25 are both used to abut against the negative terminal of the battery 800, thereby facilitating the identification and assembly of the first spring assembly 200 and the second spring assembly 300, and facilitating identification and installation during subsequent battery 800 installation.
[0048] The first spring assembly 200 has two conductive springs 2. One conductive spring 2 engages with the first latch 12 at its center, and the other conductive spring 2 engages with the first latch 12 at its edge. Specifically, the conductive spring 2 has a locking hole 26 at its center, and the first latch 12 engages with the locking hole 26. The fact that one conductive spring 2 has a locking hole 26 while the other does not, allows for differentiation between the two conductive springs 2, preventing incorrect installation on the spring holder 1 and serving a foolproof function.
[0049] The conductive spring 2 also includes an extension 27, which extends out of the outer side of the spring holder 1 and is used for soldering to the circuit board 100. Specifically, the circuit board 100 is provided with a socket 110, and the extension 27 extends into the socket 110 before being soldered to the circuit board 100, improving soldering reliability. The spring holder 1 is also provided with a second latch 14, and the extension 27 is engaged with the second latch 14 to prevent deformation of the extension 27. Since the first spring assembly 200 includes two conductive springs 2, its spring holder 1 is correspondingly provided with two second latches 14, which are used to engage with the extensions 27 of the two conductive springs 2 respectively.
[0050] The circuit board 100 is provided with at least one first spring contact assembly 200 and at least one second spring contact assembly 300, with each pair of spring contact assemblies corresponding to the other. The first spring contact assembly 200 and the second spring contact assembly 300 form a pair of spring contact assemblies for mounting a group of batteries 800, such as two batteries 800 connected in series. When multiple spring contact assemblies are provided, multiple groups of batteries 800 can be mounted, increasing the number of batteries 800. The specific number of spring contact assemblies can be set according to actual needs, offering good applicability. Specifically, multiple pairs of spring contact assemblies are independently configured, and multiple groups of batteries 800 are connected in parallel.
[0051] The battery compartment also includes a housing assembly 400, with the spring holder 1 and circuit board 100 connected to the housing assembly 400 to form a housing space 600 for accommodating the battery 800. Further, the spring holder 1 is a flat plate, and the conductive springs 2 of the first spring assembly 200 and the conductive springs 2 of the second spring assembly 300 are arranged facing each other along a first direction. The housing assembly 400 includes a first housing 410 and a second housing 420. The first housing 410 includes a base plate and a groove 411 with its opening facing a second direction. The end of the spring holder 1 is embedded in the groove 411. The circuit board 100 is connected to the base plate by a fastener 500, such as a screw. The screw passes through the circuit board 100 and the base plate and is threaded into a threaded hole on the base plate, thus assembling the circuit board 100 with the housing assembly 400 and ensuring installation stability. The first housing 410 and the second housing 420 are detachably connected along a third direction. The first housing 410 and the second housing 420 can be connected by snap-fit or by fasteners 500 such as screws, without limitation. The first direction, the second direction, and the third direction are arranged at angles to each other. In this embodiment, two sets of spring clip assemblies are provided, namely two first spring clip assemblies 200 and two second spring clip assemblies 300. The two first spring clip assemblies 200 are arranged between the two second spring clip assemblies 300 along the first direction. Correspondingly, the first housing 410 has four grooves 411 along the first direction, and four spring clip seats 1 are correspondingly embedded in the four grooves 411 for fixing the spring clip seats 1. After the first housing 410 and the second housing 420 are installed along the third direction, they are used to limit and fix the spring clip seats 1 along the third direction, ensuring the installation stability of the spring clip seats 1.
[0052] During assembly, the spring holder 1 and the conductive spring 2 are first assembled, and the first spring assembly 200 and the second spring assembly 300 are assembled with the circuit board 100. The above structure can be supplied as a single unit. Then, the circuit board 100 and the spring holder 1 are assembled with the first housing 410. The spring holder 1 is embedded in the groove 411, and the circuit board 100 and the first housing 410 are connected by screws. Finally, the first housing 410 and the second housing 420 are connected by screws to form the battery compartment.
[0053] For example, battery 800 is a lithium battery or an AA battery, etc., without limitation.
[0054] For example, four lithium batteries are divided into two groups and respectively installed in two sets of spring clip assemblies in the battery compartment.
[0055] When removing the 800 battery, an easy-pull rope can be used, which can be done by referring to existing technology, and will not be described in detail here.
[0056] This embodiment also provides an electronic device including a battery compartment as described above, which has advantages such as good contact of the battery 800, convenient installation of the battery 800, and a good user experience. Exemplarily, the electronic device is a scanner-type device. Optionally, the housing assembly 400 is a component of the outer casing of the electronic device, thereby simplifying the structure. Optionally, the housing assembly 400 and the outer casing of the electronic device are separate structures, with the housing assembly 400 detachably connected to the outer casing, adaptable to any electronic device.
[0057] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
