Description

Technical Field

[0001] This invention relates to the field of electric wind instruments, specifically to a removable rechargeable battery for electric wind instruments. Background Technology

[0002] An electronic wind instrument is a type of electronic instrument that simulates the sound of traditional wind instruments (such as the saxophone and flute). Combining electronic technology with the playing techniques of traditional wind instruments, electronic wind instruments are commonly used in modern music composition, particularly in electronic music, jazz, and pop. They simulate the sound of natural instruments like the saxophone using electronic components. Typically long and slender, they usually consist of pipes, sensors, buttons, a display screen, an air supply, and a power source.

[0003] For example, a long-life electric wind instrument disclosed in Chinese Patent Publication No. CN214897587U includes a tube body and a mouthpiece. The tube body includes an upper shell, a lower shell, and a circuit board assembled inside the upper and lower shells. The upper shell has a recessed playing area with multiple playing keys distributed therein. Protrusions are provided between the multiple playing keys. The edges of the upper and lower shells are respectively provided with complementary stepped structures. The two stepped structures are spliced ​​together and fit together. One of the stepped structures has a notch on its outside. The lower shell has a battery compartment and a battery cover assembled on the battery compartment in the middle. The battery cover has a raised finger support. The upper and lower shells are fastened together by a connecting post interlocking structure.

[0004] However, in current technology, the battery of a wind instrument is usually fixed directly to the outside of the instrument. If the wind instrument runs out of power during use, it needs to be recharged. However, the wind instrument cannot be used during the charging process. Furthermore, the battery temperature tends to rise during use. To improve the battery's lifespan, it needs to be cooled. Existing cooling devices typically use structures such as fan blades, which have a strong heat dissipation effect, but they also generate unnecessary noise during the cooling process, thus affecting the use of the wind instrument. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a removable rechargeable battery for electric wind instruments, so as to solve the technical problems of inconvenience in using electric wind instruments when charging and poor heat dissipation of batteries.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detachable rechargeable battery for a wind instrument, comprising a battery installed inside the body of the wind instrument, the outer wall of the battery being a protective shell, a cover plate connected to the top of the inside of the battery, a heat dissipation structure provided between the cover plate and the battery, grooves provided on both sides of the battery, a push button installed on the inner wall of the battery, a sliding plate installed on the inner wall of the push button, limit blocks installed on the outer side walls of the sliding plate, a positioning plate and a control circuit board installed inside the battery, the push button being movably connected to the battery through the control circuit board, and a battery storage group installed on both sides of the control circuit board inside the battery, with a terminal connected between the battery storage group and the control circuit board.

[0007] By adopting the above technical solution, during use, the battery is first installed into the mounting slot. The finger is pressed into the groove, and the push button is pushed to move the sliding plate, allowing the limiting block to enter the battery. Then, the battery is inserted into the mounting slot, the pressure on the push button is released, the spring pushes the sliding plate back to its original position, and the limiting block is inserted into the fixing slot, thereby fixing and limiting the battery. During battery use, heat can be discharged through the space between the cover and the battery, thereby dissipating heat from the battery.

[0008] The invention is further configured such that a mounting groove is provided on the back of the main body of the electric blowpipe, and an electrical connection port and a fixing groove are respectively installed on the inner wall of the mounting groove. The electrical connection port is located at the bottom end of the mounting groove and is evenly distributed on the inner wall of the mounting groove.

[0009] Preferably, the battery can be easily installed, and after installation, the battery is positioned by the mounting slot.

[0010] The present invention is further configured such that the size of the battery matches the mounting groove, the bottom end of the battery has a plug that matches the power interface, the size of the limiting plug matches the fixing groove, and a positioning screw is installed at the connection position of the battery.

[0011] Preferably, the battery can be easily assembled and fixed in the mounting slot.

[0012] The present invention is further configured such that a sliding groove is provided in the middle position of the positioning plate, a positioning shaft is connected to the back of the sliding plate, and the positioning shaft passes through the back of the sliding groove and is connected to the positioning plate. The positioning shaft is engaged with the positioning plate through the positioning plate, and a spring is sleeved on the outside of the positioning shaft.

[0013] Preferably, the push button and the sliding plate are easily pushed back to their original positions, so that the limiting plug can be moved to the outside of the battery during battery installation.

[0014] The present invention is further configured such that a buffer air cushion is installed between the battery and the cover plate. The buffer air cushion is an elastic air bladder, and an opening is provided on the side of the buffer air cushion. When the cover plate is squeezed, the buffer air cushion contracts and discharges some of the internal air, thus isolating the cover plate from the battery.

[0015] Preferably, the battery can be easily cooled, and during the cooling process, the cover plate and the battery are isolated by a buffer air cushion to prevent the cover plate from overheating.

[0016] The present invention is further configured such that a heat dissipation groove is provided between the battery and the cover plate, a heat dissipation mesh is installed on the top of the battery above the energy storage group, and a plug rod and a positioning rod are installed on the bottom of the cover plate. The plug rod is inserted into the battery and is located between the positioning plates. The outer wall of the plug rod is provided with a locking groove that matches the positioning plate. The positioning plate is rhomboid in shape.

[0017] Preferably, it can facilitate the dissipation of battery heat, and during the heat dissipation process, the cover plate can be limited by the engagement between the positioning plate and the plug rod, keeping the heat dissipation slot continuously open.

[0018] The invention is further configured such that a spring rod is connected to the bottom end of the positioning rod, the positioning rod is movably connected to the battery through the spring rod, and a contact head is installed on the inner wall of the positioning rod. When the cover is closed, the contact head is separated from the contactor, and when the cover is opened, the contact head is connected to the contactor.

[0019] Preferably, the cover can be opened by a spring rod, and during battery installation, the connector can be connected to the battery terminal, so that the current in the battery can supply power to the blowpipe through the battery.

[0020] In summary, the present invention has the following main beneficial effects:

[0021] 1. The present invention, through the battery, enables continuous use of the blowpipe by directly replacing the battery during use. During use, the battery is further restrained by supporting it with the thumb. Furthermore, the space between the battery and the cover plate allows for heat dissipation of the battery while avoiding unnecessary noise during the heat dissipation process.

[0022] 2. The present invention, through the battery configuration, allows for the installation of a buffer air cushion between the battery and the cover plate. The air cushion not only facilitates heat dissipation for the battery but also isolates the cover plate from the battery itself, thereby preventing the cover plate from overheating during heat dissipation and affecting user operation.

[0023] 3. The present invention also features a battery and a push button. During battery installation, the positioning plate separates from the locking groove, and the spring rod pushes the cover plate to separate from the battery. At the same time, the battery pack is connected to the control circuit board, enabling the battery to operate normally. This exposes the heat dissipation mesh to the outside air, facilitating heat dissipation for the battery. When disassembling the battery, pressing the push button releases the battery from its fixation. Simultaneously, pressing the cover plate returns it to its original position, disconnecting the battery pack from the outside environment and cutting off the battery power. This ensures that the battery power will not discharge to the outside, reducing damage to the blowpipe during removal. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The embodiments of the present invention will now be described.

[0042] First embodiment:

[0043] Please see Figures 1 to 7The device includes a battery 2, which is installed inside the main body 1 of the blowpipe. A mounting groove 101 is provided on the back of the main body 1. A power inlet 102 and a fixing groove 103 are respectively installed on the inner wall of the mounting groove 101. The power inlet 102 is located at the bottom of the mounting groove 101 and is evenly distributed on the inner wall of the mounting groove 101. The size of the battery 2 matches the mounting groove 101. A plug matching the power inlet 102 is provided at the bottom of the battery 2. The size of the limiting plug 4 matches the fixing groove 103. The slot 103 is matched, and a positioning bolt 204 is installed at the connection position of the battery 2. The end of the positioning bolt 204 is a cylindrical structure, which is used to limit the battery 2. The outer wall of the battery 2 is a protective shell 201, and a cover plate 202 is connected to the top of the inside of the battery 2. A buffer air cushion 205 is installed between the battery 2 and the cover plate 202. The buffer air cushion 205 is an elastic airbag, and an opening is opened on the side of the buffer air cushion 205. When the cover plate 202 is squeezed, the buffer air cushion 205 contracts and discharges. Part of the air is separated from the battery 2 by a cover plate 202. The battery 2 has grooves 203 on both sides. A push button 3 is installed on the inner wall of the battery 2. A sliding plate 301 is installed on the inner wall of the push button 3. Limiting blocks 4 are installed on the outer side of the sliding plate 301. A positioning plate 206 and a control circuit board 207 are installed inside the battery 2. The push button 3 is movably connected to the battery 2 through the control circuit board 207. During installation, first insert your finger into the groove 203 and squeeze the push button 3 so that the push button 3 drives the limiting blocks 4 into the battery 2. Then insert the battery 2 into the mounting slot 101 to lock the battery 2. After releasing the pressure on the push button 3, the push button 3 returns to its original position. The sliding plate 301 drives the limiting blocks 4 to lock into the fixing slot 103, thereby fixing the battery 2. A battery storage group 5 is installed on both sides of the control circuit board 207 inside the battery 2. A terminal 208 is connected between the battery storage group 5 and the control circuit board 207.

[0044] In the above embodiment, please refer to the figure for details. A groove is provided in the middle of the positioning plate 206. The back of the sliding plate 301 is connected to the positioning shaft 302. The positioning shaft 302 passes through the back of the groove and is connected to the positioning plate 303. The positioning shaft 302 is engaged with the positioning plate 206 through the positioning plate 303. A spring is sleeved on the outside of the positioning shaft 302 to facilitate pushing the sliding plate 301 and the push key 3 back to their original positions.

[0045] Second embodiment:

[0046] Please see Figures 8 to 14A heat dissipation groove 209 is provided between the battery 2 and the cover plate 202. A heat dissipation mesh 210 is installed on the top of the battery 2 above the battery pack 5. A plug rod 211 and a positioning rod 212 are installed at the bottom of the cover plate 202. The plug rod 211 is inserted into the battery 2 and is located between the positioning plate 206 and the positioning plate 303. The outer wall of the plug rod 211 has a locking groove 211a that matches the positioning plate 303. The positioning plate 303 is rhomboid. During the testing process, the positioning plate 303 can be connected to the locking groove 211a. The cover 202 is locked in place by a locking mechanism. A spring rod 212a is connected to the bottom of the positioning rod 212. The positioning rod 212 is movably connected to the battery 2 via the spring rod 212a. A connector 212b is installed on the inner wall of the positioning rod 212. When the cover 202 is closed, the connector 212b is separated from the connector 208. When the cover 202 is open, the connector 212b is connected to the connector 208. This allows the battery pack 5 to be connected and used normally after the battery 2 is installed, thus facilitating heat dissipation after power supply and improving the heat dissipation effect.

[0047] During use, battery 2 needs to be charged first. After charging is complete, insert your index finger and thumb into the groove 203 respectively, and press the push button 3 with your fingers. Then press the push button 3. At this time, the push button 3 drives the sliding plate 301 to move, thereby driving each set of limiting blocks 4 into the battery 2 and clamping the battery 2. Move the battery 2 to align it with the mounting groove 101 on the back of the blowpipe body 1, and insert the battery 2 into the mounting groove 101. The power port 102 is connected to the plug at the bottom of the battery 2. At this time, the push button 3 is no longer pressed. The spring on the outside of the positioning shaft 302 pushes the sliding plate 301 and the push button 3 back to their original positions. The sliding plate 301 drives the limiting blocks 4 to insert into the inner wall of the fixing groove 103. This secures the battery 2, which then powers the main body 1 of the blowpipe, enabling normal use. During use, the user's thumb rests on the battery 2, and the fingers operate the various buttons on the main body 1 of the blowpipe to achieve normal operation. During use, the heat generated by the battery 2 is dissipated through the gap under the cover 202, thus cooling the battery and reducing noise during heat dissipation. When the battery 2 is depleted, the user inserts their finger into the groove 203 and presses the push button 3 to push the limiting block 4 out of the fixing groove 103, releasing the limitation on the battery 2. The battery 2 is then removed, and a fully charged battery 2 is reinstalled into the mounting groove 101 for uninterrupted use.
