[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Refer to Figures 1 - 11 , a recorder supporting hot swapping of batteries, comprising:

[0045] Recorder 100;

[0046] Battery compartment 101 provided on one side of the recorder 100;

[0047] Battery interface 102 provided on one side of the battery compartment 101, the battery interface 102 has a plurality of electrical contacts, the electrical contacts are made of conductive materials and are connected to the power management module of the main board of the recorder 100 for supplying power to the recorder 100;

[0048] The main battery 103 and the secondary battery 104 are disposed in the battery compartment 101. The electrical contacts of the main battery 103 are in contact with the electrical contacts on the battery interface 102, and there is a preset spacing between the main battery 103 and the secondary battery 104;

[0049] The two heat dissipation fins 105 in the battery compartment 101 are respectively located on the upper and lower sides of the battery compartment 101;

[0050] The elastic member disposed between the battery compartment 101 and the secondary battery 104 is used to replace the position of the main battery 103 when the main battery 103 is detached from the battery compartment 101;

[0051] The locking member disposed between the battery compartment 101 and the main battery 103 is used to lock the position of the secondary battery 104 when the main battery 103 is latched at a preset position in the battery compartment 101;

[0052] The heat dissipation member disposed between the battery compartment 101 and the secondary battery 104 is used to move the lower heat dissipation fin 105 to the left side of the secondary battery 104 when the secondary battery 104 is at the preset position a, and move the upper heat dissipation fin 105 to the right side of the secondary battery 104 when the secondary battery 104 is at the preset position b;

[0053] By setting up the battery compartment 101, during application, the secondary battery 104 can be first snapped into the battery compartment 101. A certain frictional force is formed between the battery and the battery compartment 101. When the secondary battery 104 is at the preset position a, it contacts the elastic component, and the electrical contacts on the secondary battery 104 can contact the electrical contacts on the battery interface 102. Subsequently, the primary battery 103 is snapped into the battery compartment 101. When the primary battery 103 is inserted into the battery compartment 101, the primary battery 103 will push the secondary battery 104 to move in the preset direction, and at the same time, the elastic component gradually stores energy during the movement of the primary battery 103. As the primary battery 103 is further inserted, the electrical contacts of the primary battery 103 establish contact with the electrical contacts on the battery interface 102, providing power for the recorder 100. During this process, the electrical contacts on the secondary battery 104 gradually disengage from the electrical contacts of the battery interface 102 until the primary battery 103 reaches the preset position a. At this time, the primary battery 103 is fully connected to the battery interface 102 and the power supply is turned on. At this time, the electrical contacts on the secondary battery 104 are completely disengaged from the battery interface 102 and no longer supply power to the device, ensuring that the primary battery 103 provides stable power. In this application, by using the electrical interface with a relatively large width on the battery interface 102, the connection stability of the electrical contacts of the primary battery 103 and the secondary battery 104 at different insertion positions can be guaranteed. The wide electrical interface can ensure that multiple contacts are in contact simultaneously, increasing the contact area between the battery and the battery interface 102, reducing the contact resistance, and avoiding current fluctuations caused by poor contact. In addition, this design can also effectively increase the redundancy of the battery interface 102, ensuring that even if some contacts fail, other contacts can still maintain power supply, thereby improving the reliability of the battery system. In addition, because the secondary battery 104 is pushed by the primary battery 103 from the preset position a to the preset position b, the elastic component set at this time will gradually store energy. To ensure the stability of the secondary battery 104 and the primary battery 103 in the battery compartment 101, a locking component is added, which can lock the position of the secondary battery 104 when the primary battery 103 is snapped into the preset position in the battery compartment 101, ensuring the stability of the secondary battery 104 and the primary battery 103 in the battery compartment 101. Only when the primary battery 103 is pulled out or replaced, the locking component will be released, allowing the secondary battery 104 to return to the accessible state and reconnect to the battery interface 102 to provide backup power. The primary battery 103 provides the main power. When the primary battery 103 is fully inserted and the power supply is turned on, the locking component ensures the stable position of the secondary battery 104, avoiding poor battery contact or power interruption due to the action of the elastic component. When the primary battery 103 is pulled out or disconnected, the energy stored in the elastic component will be quickly released, pushing the secondary battery 104 to move to the predetermined position and making the electrical contacts of the secondary battery 104 contact the contacts on the battery interface 102 again to restore power supply.During this process, the design of the elastic component is crucial. It needs to have appropriate elasticity and elastic force to ensure that after the main battery 103 is detached, the secondary battery 104 can complete the position conversion within a short time, quickly contact the battery interface 102, and avoid power supply interruption. Through this design, not only is a seamless transition during the battery replacement process ensured, but also the battery usage efficiency and the stability of the device are improved. After the main battery 103 is detached, the secondary battery 104 can immediately take over the power supply task, avoiding power interruption and enhancing the working continuity and reliability of the recorder 100. Further, heat dissipation fins 105 are respectively provided at the top and bottom of the battery compartment 101. In its working state, when the secondary battery 104 is at the preset position a, the heat dissipation fin 105 below moves to the left side of the secondary battery 104, and the working secondary battery 104 can be effectively cooled through the heat dissipation fin 105 below. When the secondary battery 104 is at the preset position b, the heat dissipation fin 105 above moves to the right side of the secondary battery 104. At this time, the heat dissipation fin 105 above can be inserted into the preset spacing between the main battery 103 and the secondary battery 104 to effectively cool the working main battery 103. This prevents the battery temperature from being too high, thereby extending the service life of the battery and maintaining the stability of the device. This design ensures that both the main battery 103 and the secondary battery 104 can obtain appropriate heat dissipation within the battery compartment 101, avoiding performance degradation or failures caused by overheating between the batteries. This dynamic adjustment method of the heat dissipation system enables the battery compartment 101 to automatically optimize the heat dissipation effect according to the position of the battery in different working states. It can effectively reduce the working temperature of the battery and prevent the battery from suffering from performance attenuation or damage due to overheating.

[0054] As a further solution of the present invention, a battery tray 106 is provided in the battery compartment 101. The battery interface 102 is provided on the battery tray 106. The main battery 103 and the secondary battery 104 are located within the battery tray 106. The heat dissipation fins 105 are located within the battery tray 106. Heat dissipation openings 107 adapted to the heat dissipation fins 105 are respectively formed at the top and bottom of the battery tray 106. The heat dissipation fins 105 are inserted into the battery tray 106 through the heat dissipation openings 107;

[0055] By providing the battery tray 106, a cavity is formed between the battery compartment 101 and the battery tray 106, providing sufficient space for the heat dissipation of the heat dissipation fins 105. This cavity helps the free insertion of the heat dissipation fins 105 and can also ensure that the heat dissipation fins 105 can effectively take away the heat generated by the battery during operation.

[0056] As a further solution of the present invention, the elastic component includes a storage opening 200 formed on one side of the battery compartment 101. A connecting rod a201 is rotatably connected in the storage opening 200. A limiting shaft 202 is connected to the connecting rod a201. The limiting shaft 202 is slidably connected to the storage opening 200. A connecting rod b203 is rotatably connected to the limiting shaft 202. A spring a204 is provided between the connecting rod b203 and the connecting rod a201. One end of the connecting rod b203 is connected to a push plate 205;

[0057] By providing the above elastic component, the secondary battery 104 pushes the push plate 205, the limiting shaft 202 slides in the storage opening 200, the connecting rod a201 and the connecting rod b203 rotate, causing the spring a204 to twist and store potential energy, preparing for the subsequent replacement of the secondary battery 104. When the main battery 103 is detached from the battery compartment 101, the elastic component releases the stored potential energy through the rotation of the connecting rod and the twisting action of the spring, pushing the secondary battery 104 to move to the preset position a, ensuring that the secondary battery 104 can be timely connected to the battery interface 102 and continue to supply power to the recorder 100. The key to this design lies in the role of the spring a204. By storing the torsional potential energy of the spring a204, the secondary battery 104 can be quickly pushed to the predetermined position when the main battery 103 is detached, avoiding power interruption during the battery replacement process. The coordinated work between the connecting rod a201 and the connecting rod b203 enables the entire structure to provide sufficient thrust while maintaining the stability of the secondary battery 104 in the battery compartment 101.

[0058] As a further solution of the present invention, the heat dissipation component includes a rotating shaft 300 rotatably connected in the battery compartment 101. A gear 301 is connected to the rotating shaft 300. A rack 302 meshing with the gear 301 is connected to the heat dissipation fin 105;

[0059] By setting the heat dissipation fins 105, when the battery holder 106 is empty in the initial state, the lower heat dissipation fins 105 extend into the battery holder 106, while the upper heat dissipation fins 105 are not inserted into the battery holder 106. When initially inserting the secondary battery 104, the position of the lower heat dissipation fins 105 remains unchanged. When the secondary battery 104 does not supply power to the recorder 100, the lower heat dissipation fins 105 can dissipate heat for the working secondary battery 104. When subsequently continuing to insert the main battery 103, when the main battery 103 pushes the secondary battery 104 to move to the preset position b, the rotating shaft 300 can be rotated at this time, so that the rotation drives the heat dissipation fins 105 to displace through the gear 301 and the rack 302. The lower heat dissipation fins 105 move downward to avoid the position of the secondary battery 104, and the upper heat dissipation fins 105 gradually insert into the battery holder 106 through the heat dissipation opening 107 to dissipate heat for the working secondary battery 104. Through the drive of rotation and the gear 301 and the rack 302, the entire heat dissipation system flexibly adjusts the position of the heat dissipation fins 105 to ensure that both the main battery 103 and the secondary battery 104 can obtain effective heat dissipation during the power supply state, ensure the temperature balance in the battery holder 106, and improve the efficiency and service life of the battery system.

[0060] As a further solution of the present invention, the heat dissipation component further includes a connection groove 303 opened on the secondary battery 104. A push bar 304 is slidably connected to the battery holder 106. A spring b 305 is connected between the push bar 304 and the battery holder 106. One side of the push bar 304 is connected with a traction rope a 306. One end of the traction rope a 306 is wound around the rotating shaft 300. A spring c 307 is provided between the rotating shaft 300 and the battery holder 106.

[0061] By setting the push bar 304, after the secondary battery 104 reaches the preset position a, when it further moves towards the preset position b, the push bar 304 can be pushed through the connecting groove 303. One side of the push bar 304 is connected to the rotating shaft 300 through the traction rope a306. One end of the traction rope a306 is wound around the rotating shaft 300. With the pushing of the push bar 304, the traction rope drives the rotating shaft 300 to rotate. The rotation of the rotating shaft 300, through the gear 301 and rack 302 mechanism, displaces the heat dissipation fins 105 to ensure that the heat dissipation fins 105 can be automatically adjusted according to the position of the battery. Especially when the secondary battery 104 moves towards the preset position b, the rotation of the rotating shaft 300 causes the lower heat dissipation fins 105 to avoid the position of the secondary battery 104, and at the same time causes the upper heat dissipation fins 105 to be gradually inserted into the battery bracket 106 through the heat dissipation opening 107, providing more efficient heat dissipation. In addition, the provided spring b305 and spring c307 can provide a certain force for the reset of the push bar 304 to ensure that the push bar 304 can maintain a stable movement during the movement of the secondary battery 104. When there may be a certain frictional force between the secondary battery 104 and the battery bracket 106, the spring b305 helps the push bar 304 overcome the frictional force by providing an appropriate restoring force, ensuring that the push plate 205 and the push bar 304 can smoothly push the secondary battery 104 towards the preset position a when the subsequent main battery 103 is detached.

[0062] As a further solution of the present invention, the locking component includes a locking opening 400 opened on the push bar 304. A positioning rod 401 is provided in the locking opening 400. The top of the positioning rod 401 is connected to a force-bearing plate 402. A lead screw 403 is rotatably connected in the battery compartment 101. A threaded tube 404 that is threadedly connected to the lead screw 403 and slidably connected to the battery compartment 101 is provided. A spring d405 is connected between the force-bearing plate 402 and the push bar 304;

[0063] By setting the lead screw 403, when storing the main battery 103 and pushing the secondary battery 104 to the preset position b, the lead screw 403 can be rotated to make the threaded tube 404 rotate along the lead screw 403 and push the force-bearing plate 402. The movement of the force-bearing plate 402 acts through the positioning rod 401 to squeeze and contact the connecting groove 303, thereby positioning the secondary battery 104. During this process, the rotation of the lead screw 403 drives the threaded tube 404 to slide along the battery compartment 101, and the precise control of the position of the secondary battery 104 is achieved through the positioning rod 401 connected to the threaded tube 404. By rotating the lead screw 403, the threaded tube 404 pushes the force-bearing plate 402, further pushing the positioning rod 401 to move within the locking port 400. When the positioning rod 401 contacts the connecting groove 303 on the secondary battery 104, the position of the secondary battery 104 can be locked to ensure that the secondary battery 104 is stably positioned within the battery compartment 101. This design ensures that after the main battery 103 is inserted and pushed, the secondary battery 104 can be accurately and firmly locked in the preset position b, ensuring the stability and reliability of the battery system.

[0064] As a further solution of the present invention, the positioning rod 401 includes a top rod a406 connected to the force-bearing plate 402. The bottom of the top rod a406 is slidably connected to a top rod b407, and a spring e408 is connected between the top rod a406 and the top rod b407;

[0065] By setting the spring e408, the elastic force provided by the spring e408 ensures that the contact force between the top rod a406 and the top rod b407 is appropriate, thereby realizing a slight extrusion and precise positioning of the secondary battery 104 without causing excessive pressure on the battery. This design ensures that the battery can be stably and accurately locked in the predetermined position while maintaining good contact of the battery interface 102, avoiding the situation of battery damage caused by excessive compression.

[0066] As a further solution of the present invention, the locking component further includes a rotating cavity 500 opened on the battery bracket 106. A friction roller 501 is rotatably connected in the rotating cavity 500. A traction rope b502 is wound around the friction roller 501. One end of the traction rope b502 passes through the battery bracket 106 and extends into the battery compartment 101 and is wound around the lead screw 403. A spring f503 is provided between the lead screw 403 and the battery compartment 101, and a spring g504 is provided between the friction roller 501 and the rotating cavity 500;

[0067] By setting the friction roller 501, a rubber ring can be provided on the outer wall of the friction roller 501. When the secondary battery 104 is inserted into the battery bracket 106, as the secondary battery 104 moves, the friction force causes the friction roller 501 to rotate. At this time, the traction rope b502 can be wound up to rotate the lead screw 403. The rotation of the lead screw 403 can move the position of the threaded tube 404 downward. Since the push bar 304 has not reached the limit position at this time (the secondary battery 104 has not reached the preset position b), the movement of the threaded tube 404 will not interfere with the force receiving plate 402. When the main battery 103 is subsequently inserted into the battery bracket 106, the secondary battery 104 is separated from the friction roller 501, and the springs f503 and g504 release their potential energy to move the threaded tube 404 back to its original position. When the main battery 103 is inserted and moves, it will contact the friction roller 501 and cause it to rotate again. When the push bar 304 and the force receiving plate 402 reach the position of the threaded tube 404, the threaded tube 404 contacts the force receiving plate 402, and the force receiving plate 402 slides under the threaded tube 404. As the threaded tube 404 continues to move, the positioning rod 401 can be made to completely abut against the connecting groove 303, accurately positioning the secondary battery 104 at the preset position b.

[0068] As a further aspect of the present invention, a heat dissipation cover plate 505 is connected to one side of the main battery 103, and the heat dissipation cover plate 505 provides a preset spacing between the main battery 103 and the secondary battery 104;

[0069] By setting the heat dissipation cover plate 505, a heat dissipation space between the main battery 103 and the secondary battery 104 can be effectively provided. The increase in the heat dissipation space helps to enhance the heat dissipation effect.

[0070] As a further aspect of the present invention, a battery cover plate 506 is provided on one side of the recorder 100;

[0071] By setting the battery cover plate 506, the battery cover plate 506 is connected to the recorder by a snap connection method to provide a limit for the main battery 103 or the secondary battery 104.

[0072] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
