Technical Field
[0001] This utility model relates to the field of speaker batteries, and more specifically, to a battery module for speakers. Background Technology
[0002] Detachable batteries are currently one of the most popular types of speakers with battery storage capabilities. The ability to remove and replace batteries makes maintenance and replacement easier, and also allows for the addition of backup batteries to extend battery life.
[0003] In actual use, it's inevitable that the speaker will sometimes be unused for extended periods. Some users will remove the battery and store it separately, while others will simply leave it in the battery compartment. The former requires placing the battery in a suitable location for better protection, but improper storage may accelerate damage and may lead to forgetting its location, requiring a lengthy search, which is quite troublesome. The latter involves the battery's contact points remaining physically connected to external conductive terminals. Even when the device is off, the battery's internal electrochemical system will still form a micro-current loop through the contact terminals, accelerating self-discharge. Furthermore, under prolonged power-on conditions, ambient humidity and the potential difference between the electrodes can easily cause electrochemical corrosion of the metal contacts, affecting battery life. Therefore, improvements are needed. Utility Model Content

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0026] like Figures 1 to 4 As shown in the figure, a specific embodiment of the present invention discloses a battery module for a speaker, including a battery body 100 and a battery box 200 for placing the battery body 100; the bottom surface of the battery body 100 is provided with a power receiving terminal 110, and the bottom of the battery box 200 is provided with a first through hole 240 for inserting an external plug; a box cover 300 is installed on the top of the battery box 200; the power receiving terminal 110 is recessed in the bottom surface of the battery body 100; the battery body 100 has a columnar structure, which is adapted to the shape of the receiving cavity 210 of the battery box 200, and both ends of the battery body can be inserted into the receiving cavity.
[0027] The aforementioned speaker battery module allows the battery to be inserted into the battery compartment in either the forward or reverse orientation. During normal use, the battery can be inserted forward, allowing the battery's terminals to make contact with the plug inside the battery compartment. When the speaker is not planned to be used for an extended period, the battery can be inserted backward, disengaging the battery's terminals from the plug, thus slowing down self-discharge, preventing corrosion and damage to the battery contacts, and extending its service life. The entire system is simple and convenient to use, requiring only the reversal of the insertion direction.
[0028] Furthermore, such as Figure 4 , Figure 5As shown, the top of the battery box 200 is provided with a first recess 220. One end of the box cover 300 is rotatably mounted in the first recess 220 via a pivot 400. A torsion spring 500 is sleeved on the pivot 400 to provide opening elasticity for the box cover 300. A locking structure 600 is installed at the end of the box cover 300 away from the pivot. The locking structure 600 includes an adjustable locking tongue 610. A slot is provided on the inner wall of the first recess 220. The protruding locking tongue 610 can extend into the slot to keep the box cover closed. The box cover is rotatably mounted on the battery box and can automatically spring open when opened for easy operation. When closed, the locking tongue is inserted into the slot, and the torsion spring is also continuously applying force, thus forming an effective closed connection, effectively blocking and sealing the top of the receiving cavity, and providing better protection for the battery body.
[0029] Furthermore, one end of the lid has a first through hole penetrating two opposite side walls, and both ends of the first through hole have slots for holding the torsion spring and limiting the first torsion arm at one end of the torsion spring; the bottom of the first recess has a first clamping groove corresponding to the second torsion arm at the other end of the torsion spring, so that the torsion spring can be better installed in the corresponding position and provide the necessary deformation space for the torsion spring; and the rotating shaft is a long bolt structure, with corresponding holes on the two opposite side walls of the first recess, and is installed by threaded connection, and the part of the long bolt corresponding to the lid is a smooth rod structure, so that the lid can rotate and swing smoothly; it should be noted that the rotating shaft includes, but is not limited to, a long bolt structure, and can also be a pin, a column pin, or a shaft strip structure, as long as the corresponding installation method is used;
[0030] Furthermore, such as Figure 2 , Figure 3 As shown, the top of the two opposite sidewalls of the receiving cavity 210 is provided with a groove 230, the top of which extends to the bottom of the first sink. The two opposite sidewalls of the battery body 100 are provided with multiple strip grooves 120, which extend along the side length of the cross-section of the battery body. The multiple strip grooves are evenly spaced vertically, and some of them fall into the groove. The width of the strip groove is 1-2 mm, and they are evenly spaced at 2-4 mm intervals along the vertical direction of the battery body. The distance from the strip grooves at both ends to the two end faces of the battery body is 3-5 mm. The depth of the groove is 2-3 cm, so that enough strip grooves fall into the groove so as to serve as a gripping part of the battery body for easy picking and putting.
[0031] Furthermore, the design of the grooves, in addition to increasing friction, can also play a role in heat dissipation to some extent.
[0032] Furthermore, such as Figure 2 , Figure 3As shown, the bottom of the cover 300 is provided with a protruding rubber pad 700; when the battery body 100 is placed in the receiving cavity in reverse, the position of the rubber pad 700 corresponds to the position of the power connection terminal 110; when the cover is closed, the rubber pad is pressed tightly against the outside of the power connection terminal to completely cover and shield it; the rubber pad provides secondary shielding and sealing of the power connection terminal, further preventing the electrode of the power connection terminal from contacting the outside, and further preventing moisture or dust from adhering.
[0033] Furthermore, such as Figure 6 , Figure 7 As shown, the locking structure 600 includes a locking tongue 610 and an elastic element 620; the locking tongue 610 includes a support plate 611, and a protrusion 612 is fixedly provided on the top surface of the support plate 611; the bottom surface of the cover 300 is provided with a second recess 310, and a first strip hole 320 is provided on the groove wall of the second recess 310 away from the pivot, and the shape of the slot is adapted to the shape of the first strip hole; a second strip hole 330 is provided on the top surface of the cover 300 corresponding to the side of the first strip hole 320; a support frame 340 is provided on the bottom of the second recess 310 corresponding to the outer side of the second strip hole 330; the support plate 611 is adapted to pass through the first strip hole 320, and the protrusion 612 passes through... The second strip-shaped hole 330 extends out of the top surface of the box cover 300, and the two ends of the support plate 611 slide against the two opposite inner walls of the support frame 340; the elastic element 620 is provided between the end face of the support plate 611 and the frame wall of the support frame 340, providing an outward pushing force for the locking tongue 610, so that the insertion end of the support plate extends out of the outer wall of the box cover; a cover plate 350 is provided at the groove opening of the second recess 310 to cover and seal the bottom end of the support frame 340; making the whole structure an assembly structure, which can facilitate the processing and production of each structural component, the replacement of parts, and the assembly; and the structure is simple, and the operation is also relatively convenient, making it easy to close and open the box cover.
[0034] Furthermore, the support plate 611 is bent downwards on the side away from the insertion end to form a pushing part 613, increasing the force-bearing area; a T-shaped block is fixed on the wall of the support frame 340 away from the first strip hole to form two second clamping grooves 360, providing installation positions for the elastic element; the elastic element 620 is a spring sheet structure, and its thickness is adapted to the groove width of the second clamping groove 360; there are two elastic elements, symmetrically arranged on both sides of the support frame; one end of the elastic element 620 is clamped in the second clamping groove 360, and the other end abuts against the wall of the pushing part 613; two limiting posts 351 are fixed on the top surface of the cover plate 350, and the limiting posts 351 are set on the inner arc side of the bent part of the elastic element 620, which can further limit the elastic element and make it deform according to the preset trajectory; the double elastic element structure can provide sufficient external elastic force, so that the locking tongue can maintain the cooperation with the slot and achieve an effective locking effect;
[0035] It should be noted that elastic elements include, but are not limited to, sheet spring structures; they can also be spring structures. The mounting location can be deformed accordingly. This is a common and frequently used fitting method, and will not be elaborated on in detail.
[0036] Furthermore, a limiting ring 710 is fixedly provided on the top side wall of the rubber pad 700; a second through hole 352 is provided on the cover plate 350, the shape of the second through hole 352 is adapted to the shape of the rubber pad 700; a limiting frame 353 is fixedly provided on the top surface of the cover plate 350 outside the second through hole, the inner wall shape of the limiting frame 353 is adapted to the shape of the limiting ring 710; after the cover plate is closed and installed in place, the top surface of the limiting frame and the top surface of the limiting ring abut against the bottom of the second sink; the rubber pad is a separate structural component, which can be easily processed and produced; and the above structural design can provide stable installation conditions for the rubber pad, so that it is firmly clamped and installed on the box cover, effectively preventing loosening.
[0037] Furthermore, the rubber pad is made of soft rubber or soft silicone, which has sufficient flexibility to deform effectively without affecting the normal closing action of the lid. Furthermore, a recess similar to the power terminal can be provided on the top surface of the battery body, and it matches the corresponding battery body placement position to provide space for the rubber pad to deform, further ensuring that the normal closing action of the lid is not affected.
[0038] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model.
