Description

Technical Field

[0001] This utility model relates to the field of battery assembly, and in particular to a battery assembly component and an audio device. Background Technology

[0002] In the photography and videography industry, audio products require prolonged continuous use and are also meant to be carried around for extended periods. Currently, most audio products on the market are powered by built-in batteries. A common battery assembly structure typically involves a battery casing within the device, with springs and contact springs positioned at the positive and negative terminals within the battery compartment. After the battery is installed in the compartment, its positive and negative terminals are electrically connected to these springs and springs. Finally, a cover is placed over the battery compartment to complete the battery assembly.

[0003] However, due to significant differences in battery diameter, length, and contact surface depending on the battery model, batteries from different brands can easily experience poor contact during audio product use if subjected to significant vibration, shaking, or drops. This can lead to power outages and prevent the audio equipment from effectively recording programs, thus failing to meet customer needs.

[0004] In order to accommodate different battery models during the use of audio equipment, it is necessary to increase the pressure and fit of the positive and negative springs or contacts. This can lead to problems such as the battery being too loose or too tight when using other battery models, causing battery damage or poor contact. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a battery assembly assembly and an audio device, wherein the first elastic member and the second elastic member at both ends of the battery cavity are in elastic contact with the positive and negative electrodes of the battery, which can be adapted to different battery models; and the protrusion on the contact surface of the first elastic member can increase the elastic contact force of the first elastic member, making the battery assembly more stable.

[0006] The technical solution adopted by this utility model to solve its problem is: A battery assembly component, comprising: The battery compartment includes a battery cavity for installing batteries, a first connecting end, and a second connecting end, the first connecting end and the second connecting end being located at opposite ends of the battery cavity; A first elastic element is connected to the first connecting end, and a protrusion is provided on the surface of the first elastic element facing the battery cavity. The second elastic element is connected to the second connecting end.

[0007] As an optional implementation, the first elastic element includes: a first elastic segment, the first elastic segment being connected to the first connecting end; The second segment can be elastically displaced toward the first segment; A connecting segment of a projectile, wherein the connecting segment connects the first projectile segment and the second projectile segment; The protrusion is provided on the surface of the second spring segment facing the battery cavity.

[0008] As an optional implementation, the connecting spring segment is an elastic bending structure with at least one bent portion.

[0009] As an optional implementation, the first connecting end is provided with a slot for inserting a spring clip, and the spring clip is inserted into the slot for inserting a spring clip.

[0010] As an optional implementation, the first elastic segment has elastic arms on both sides, the two ends of the elastic arms are respectively connected to the first elastic segment, and the middle section of the elastic arm arches towards the inside of the battery cavity to form a protrusion. The protrusion elastically abuts against the side wall of the insert groove.

[0011] As an optional implementation, a plurality of protrusions are provided, and the plurality of protrusions are spaced apart.

[0012] As an optional implementation, the second elastic element is a conductive spring element.

[0013] As an optional implementation, it also includes: A battery cover, which is detachably mounted to the battery compartment to close the battery cavity; The third elastic element is disposed on the inner surface of the battery cover plate facing the battery cavity; When the battery cover closes the battery cavity, the third elastic member extends at least partially into the battery cavity.

[0014] As an optional implementation, the third elastic element is a foam pad or a soft rubber pad.

[0015] An audio device including the aforementioned battery assembly.

[0016] In summary, this utility model has the following technical effects: 1. After the battery is assembled into the battery cavity of the battery compartment, the first elastic member and the second elastic member can elastically abut against the two ends of the battery respectively. The elastic force of the first elastic member can press the positive terminal of the battery, and the elastic force of the second elastic member can press the negative terminal of the battery. The battery can be kept in a pressed assembly state under the action of the elastic force of the two elastic members, and it is not easy to loosen under external force.

[0017] 2. Since the surface of the first elastic element facing the battery cavity has a protrusion, the protrusion contacts the positive terminal of the battery. Therefore, the elastic force of the first elastic element can be concentrated on the positive terminal of the battery through the protrusion. This results in greater pressure at the contact point between the positive terminal of the battery and the first elastic element, and a more stable battery assembly structure.

[0026] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0027] See Figures 1-7This utility model discloses a battery assembly, including a battery compartment 10, a first elastic element 20, and a second elastic element 30. The battery compartment 10 has a battery cavity 11, a first connecting end 111, and a second connecting end 112. A battery 50 can be installed in the battery cavity 11, and the first connecting end 111 and the second connecting end 112 are located at opposite ends of the battery cavity 11. The first elastic element 20 is connected to the first connecting end 111, and the second elastic element 30 can be connected to the second connecting end 112. Since the first connecting end 111 and the second connecting end 112 are opposite each other, after the battery 50 is assembled into the battery cavity 11, the first elastic element 20 of the first connecting end 111 and the second elastic element 30 of the second connecting end 112 can contact the positive and negative terminals of the battery 50.

[0028] Specifically, a protrusion 21 is provided on the first elastic member 20. The protrusion 21 is provided on the surface of the first elastic member 20 facing the battery cavity 11. In this way, when the first elastic member 20 is in contact with the extreme end of the battery 50, it is through the protrusion 21 that it contacts the positive or negative end of the battery 50.

[0029] Based on the above structure, when using the battery assembly assembly of this utility model, after the battery 50 is assembled into the battery cavity 11, this embodiment takes the positive terminal of the battery 50 in contact with the first elastic member 20 and the negative terminal of the battery 50 in contact with the second elastic member 30 after assembly as an example for explanation.

[0030] If the assembly spacing between the first elastic member 20 and the second elastic member 30 is exactly the assembly spacing of a battery 50, then after the battery 50 is assembled into the battery cavity 11 of the battery compartment 10, the first elastic member 20 and the second elastic member 30 can elastically abut against the two ends of the battery 50 respectively. The elastic force of the first elastic member 20 can press the positive end of the battery 50, and the elastic force of the second elastic member 30 can press the negative end of the battery 50. The battery 50 can then maintain a pressed assembly state under the elastic force of the two elastic members, and it is not easy for it to loosen under external force.

[0031] Furthermore, since the first elastic member 20 has a protrusion 21 on its surface facing the battery cavity 11, and this protrusion 21 is in contact with the positive terminal of the battery 50, the elastic force of the first elastic member 20 can be concentrated on the positive terminal of the battery 50 by the protrusion 21. In this way, the pressure at the contact point between the positive terminal of the battery 50 and the first elastic member 20 is greater, the assembly structure of the battery 50 is more stable, and the power outage caused by unstable contact during equipment vibration is reduced.

[0032] Furthermore, if the size of the battery 50 is smaller than the assembly gap reserved between the first elastic member 20 and the second elastic member 30, the protrusion 21 protruding from the surface of the first elastic member 20 can compensate for the difference in assembly gap within a certain range, ensuring that the first elastic member 20 can always maintain effective contact with the positive terminal of the battery 50 through the protruding protrusion 21, reducing the situation of unstable contact due to the assembly gap being greater than the length of the small-sized battery 50.

[0033] Of course, if the size of the battery 50 is larger than the assembly gap reserved between the first elastic member 20 and the second elastic member 30, the positive and negative terminals of the battery 50 can contact the first elastic member 20 and the second elastic member 30 respectively. The two ends of the battery 50 can then compress the first elastic member 20 and the second elastic member 30, and the resulting compression stroke can compensate for the larger length of the battery 50. Furthermore, since both the first elastic member 20 and the second elastic member 30 can be compressed, the resulting compensation interval is formed by superimposing the compression amounts of the two elastic members, thus adapting to a wider range of battery 50 sizes.

[0034] It should also be noted that since the first elastic member 20 and the second elastic member 30 are in elastic contact with both ends of the battery 50 after the battery 50 is assembled, when the battery compartment 10 is subjected to external force vibration, both ends of the battery 50 can buffer the force on the battery 50 through their own elastic force, thereby achieving a shock absorption effect and reducing the possibility of the battery 50 losing power due to vibration.

[0035] As an optional implementation, the first elastic element 20 includes a first elastic segment 22, a second elastic segment 23, and a connecting elastic segment 24. The first elastic segment 22 is connected to the first connecting end 111, and the second elastic segment 23 can elastically displace toward the first elastic segment 22. The connecting elastic segment 24 connects the first elastic segment 22 and the second elastic segment 23. Based on this structure, the protrusion 21 protrudes from the surface of the second elastic segment 23 facing the battery cavity 11.

[0036] After the battery 50 is assembled into the battery cavity 11, the positive terminal of the battery 50 contacts the protrusion 21 on the second elastic segment 23 of the first elastic member 20, so that the elastic force applied by the first elastic member 20 to the battery 50 is concentrated on the protrusion 21 applied to the positive terminal of the battery 50.

[0037] Since the first elastic element 20 is formed by the first elastic segment 22, the second elastic segment 23 and the connecting elastic segment 24, the elastic force of the first elastic element 20 is formed by the superposition of the three elastic segments. When the battery 50 is assembled into the battery cavity 11 and comes into elastic contact with the second elastic segment 23, the force can be distributed to the individual elastic segments when subjected to external vibration. Each elastic segment bears part of the stress, thereby reducing the sudden changes in elastic force. Therefore, the elastic stress provided by the first elastic element 20 is more stable, and the assembly structure of the battery 50 is also more stable.

[0038] Furthermore, the second elastic segment 23 and the first elastic segment 22 are connected at intervals by connecting segment 24. In this way, in addition to the elastic force provided by its own elastic properties, the second elastic segment 23 undergoes elastic deformation. At the same time, because the interval between the second elastic segment 23 and the first elastic segment 22 also reserves a deformation interval, the elastic deformation of the first elastic element 20 formed in this way is greater, and it can adapt to the length of batteries 50 of more sizes.

[0039] It should be noted that the first segment 22, the second segment 23, and the connecting segment 24 can all be formed from a single piece of metal elastic sheet. The formed metal elastic sheet can be used to form different segments by bending or other processes.

[0040] As an optional implementation, the connecting spring segment 24 is an elastic bending structure with at least one curved portion. For example, the connecting spring segment 24 can be U-shaped, V-shaped, or wavy. Since the connecting spring segment 24 with such a structure all has a curved portion, and the curved portion has an arc-shaped opening structure, the spring segments on both sides of the curved portion of the connecting spring segment 24 can work together to resist deformation, reducing twisting or skewing caused by off-center loading, and providing more stable elastic force. At the same time, the arc structure of the curved portion allows the connecting spring segment 24 to compress and deform itself. Combined with the deformation interval between the second spring segment 23 and the first spring segment 22, the deformation interval of the battery 50 after assembly is larger, and more battery sizes can be adapted.

[0041] As an optional implementation, the first connecting end 111 is provided with an insert slot 1111, and the first elastic segment 22 is inserted into the insert slot 1111. In this way, the first elastic member 20 can be inserted into the insert slot 1111 through the first elastic segment 22, which facilitates the replacement of the first elastic member 20 and the assembly of the battery compartment 10. Moreover, the assembly of the first elastic member 20 and the battery compartment 10 is achieved through the insertion and mating of the first elastic segment 22 and the insert slot 1111, with surface-to-surface contact, resulting in a stable assembly structure.

[0042] As an optional implementation, the first spring segment 22 has elastic arms 221 on both sides of its edges. The two ends of the elastic arms 221 are respectively connected to the first spring segment 22. The middle section of the elastic arms 221 arches towards the inside of the battery cavity 11 to form a protrusion 2211. The protrusion 2211 elastically abuts against the side wall of the insert groove 1111.

[0043] Thus, after the first elastic segment 22 is inserted into the insert slot 1111, the protrusion 2211 of the elastic arm 221 continuously presses against the side wall of the insert slot 1111, which can counteract the lateral force generated when the battery 50 is installed or removed. If the battery compartment 10 vibrates, or if the battery 50 is installed at an angle, the protrusion 2211 of the elastic arm 221 can maintain a tight fit with the insert slot 1111, reducing the left and right offset or tilt of the first elastic member 20 after assembly. This allows the second elastic segment 23 of the first elastic member 20 to maintain a stable contact with the positive end of the battery 50, reducing poor contact caused by misalignment.

[0044] As an optional implementation, multiple protrusions 21 can be provided in this embodiment, and the multiple protrusions 21 are spaced apart. Specifically, the protrusions 21 may include multiple protrusions in related technologies. The elastic stress provided by the first elastic member 20 can be concentrated and applied to the positive terminal of the battery 50 by the multiple protrusions. The contact surface formed by the concentrated elastic stress of the multiple protrusions is relatively large, and the contact state between the battery 50 and the first elastic member 20 is stable. At the same time, the multiple protrusions can also form a certain friction structure on the end face of the first elastic member 20, increasing the friction on the contact surface with the battery 50, reducing the possibility of slippage and disengagement due to battery 50 shaking, and ensuring stable electrical contact structure.

[0045] Of course, in some other implementation structures, the protrusion 21 may also include an arc-shaped arch structure, a protruding rib structure, or a protruding block structure, etc.

[0046] As an optional implementation, the second elastic element 30 is a conductive spring element. Similarly, after the battery 50 is installed in the battery cavity 11, if the battery 50 is slightly displaced due to vibration or shaking during the use of the equipment, the conductive spring generates a continuous preload through its own deformation, always tightly fitting the negative terminal of the battery 50, reducing problems such as circuit disconnection caused by gaps in rigid contact.

[0047] Of course, when loading batteries 50 of different sizes, the compression of the conductive spring element can be adjusted within a certain range, effectively compensating for assembly errors (such as the size tolerance of the battery compartment 10 and the thickness deviation of the battery 50) that exist when installing batteries 50 of different sizes. In conjunction with the use of the first elastic element 20, it can accommodate the length of batteries 50 of more sizes.

[0048] As an optional implementation, a battery cover 12 is also included. The battery cover 12 is detachably mounted on the battery compartment 10. When it is necessary to assemble the battery 50 in the battery cavity 11, the battery cover 12 can be detached from the battery cavity 11, the battery cavity 11 can be opened, and after the battery 50 is assembled in the battery cavity 11, the battery cover 12 is then assembled back to the battery compartment 10 to seal the battery cavity 11, preventing the battery 50 from falling out during use. This also reduces the possibility of water or dust entering the battery cavity 11, making it safer to use.

[0049] It should be noted that the battery cover 12 and the battery compartment 10 can be detachably assembled by means of snap-fit ​​connection, fastening connection, or screws or other structures.

[0050] Specifically, a third elastic element 40 can be provided on the battery cover 12. The third elastic element 40 is located on the inner surface of the battery cover 12 facing the battery cavity 11. When the battery cover 12 closes the battery cavity 11, the third elastic element 40 extends at least partially into the battery cavity 11. In this way, after the battery 50 is assembled, the battery cover 12 is sealed in the battery compartment 10. The third elastic element 40 extending partially into the battery cavity 11 can compensate for the assembly gap between the battery 50 and the battery cover 12. The third elastic element 40 presses the battery 50 tightly in the diameter direction of the battery 50, which can also reduce the shaking of the battery 50 after assembly and play a shock absorption role.

[0051] Furthermore, the compression of the third elastic element 40 varies depending on the diameter of the battery 50, thus allowing for assembly of batteries 50 of different sizes.

[0052] As an optional implementation, the third elastic element 40 is a foam pad or a soft rubber pad.

[0053] After the battery 50 is assembled, the battery cover 12 seals the battery cavity 11. It can contact the battery 50 through materials such as foam pads or soft rubber pads and press the surface of the battery 50 firmly. The foam pads or soft rubber pads can vary their compression according to the different diameters of the battery 50 to achieve a shock absorption effect.

[0054] Furthermore, materials such as foam pads or soft rubber pads can fill assembly gaps more flexibly, making battery assembly more stable.

[0055] Of course, the third elastic element 40 can also be selected as a spring structure or a sheet structure, so that the deformation of the sheet structure or spring structure can adapt to the pressing action of batteries 50 with different diameters.
