Description
Technical Field
[0001] This utility model relates to the field of magnetic battery technology, specifically a magnetic battery pack power supply structure. Background Technology
[0002] Portable smart conferencing devices typically rely on built-in batteries or external power adapters for power. Built-in battery solutions are limited in capacity and cannot meet the needs of long meetings, requiring the meeting to be interrupted for charging. While wired power solutions can provide continuous power, the cables severely restrict the mobility and adaptability of the devices.
[0003] To address the aforementioned issues, existing technologies employ pluggable battery pack structures, such as mechanical clips, but these still have significant drawbacks. Firstly, the disassembly and assembly efficiency is low; replacing the battery requires precise alignment of the clips and the application of considerable mechanical force, with each operation taking more than 30 seconds. Furthermore, disassembly requires both hands, making seamless battery switching during meetings impossible. Additionally, the clips are prone to plastic deformation after more than 50 insertions and removals, leading to loose battery packs and poor power supply contact. The applicant discovered this issue while implementing the aforementioned solutions. Based on this, this utility model designs a magnetic battery pack power supply structure to solve the above problems. Utility Model Content

[0014] Preferably, the magnetic battery pack further includes a built-in protection circuit for overvoltage, overcurrent and short-circuit protection. The protection circuit includes an overvoltage protection module, an overcurrent protection module and a short-circuit protection module, which are integrated into the housing of the magnetic battery pack.
[0015] Preferably, the guide groove is located at the edge of the battery mounting position at the bottom of the conference machine body, and is used to slide with the positioning sector post.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0020] 1. This utility model features a magnetic battery pack that achieves quick connection and separation from the main body of the conference machine through magnetic adsorption. The battery pack can be replaced in a very short time with one hand, without the need for precise alignment or the application of large mechanical force. This effectively solves the problem of interruption due to insufficient power during long meetings, and achieves seamless power switching during the meeting. At the same time, it avoids cable constraints and greatly improves the mobility of the device and its adaptability to different meeting scenarios.
[0021] 2.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please refer to Figures 1-5 A magnetic battery pack power supply structure, comprising:
[0030] The main connection structure 1 is located at the bottom of the conference machine and includes a battery mounting position, multiple first permanent magnets 102 and power supply contacts 103. The first permanent magnets 102 form fixed adsorption points, and the power supply contacts 103 are metal spring contacts used to provide a power interface.
[0031] The magnetic battery pack 2 includes a shell, multiple second permanent magnets 202 and elastic conductive sheets 203. The second permanent magnets 202 are correspondingly arranged with the first permanent magnets 102 of the main body connection structure 1 and are used to achieve automatic positioning by magnetic attraction. The elastic conductive sheets 203 cooperate with the power supply contacts 103 to establish a power connection.
[0032] The guide positioning structure 3 includes:
[0033] Guide groove 301 is located at the bottom of the main body of the conference machine;
[0034] The positioning sector post 302 is set on the top of the housing of the magnetic battery pack 2 and cooperates with the guide groove 301 to guide the installation direction of the magnetic battery pack 2;
[0035] A ring-shaped anti-slip rubber ring 303 is installed at the bottom of the conference machine body;
[0036] An annular groove 304 is provided on the outer wall of the magnetic battery pack 2 housing and cooperates with the annular anti-slip rubber ring 303 to prevent the magnetic battery pack 2 from shifting. The guide positioning structure 3 ensures that the battery pack is accurately positioned during the adsorption process through the cooperation of the guide groove 301 with the positioning fan-shaped column 302 and the annular anti-slip rubber ring 303 with the annular groove 304.
[0037] The magnetic battery pack 2 also includes a built-in protection circuit 4 for overvoltage, overcurrent and short circuit protection. The protection circuit 4 includes an overvoltage protection module, an overcurrent protection module and a short circuit protection module, which are integrated into the housing of the magnetic battery pack 2.
[0038] In this embodiment of the invention, after the battery pack is tightly connected to the main body connection structure 1, the elastic conductive sheet 203 comes into contact with the power supply contact 103. The elastic conductive sheet 203 has elastic deformation capability and can generate a certain elastic pressure when in contact with the power supply contact 103, ensuring a good electrical connection and reducing wear on the contact during long-term insertion and removal. The power supply contact 103 is directly connected to the internal power circuit of the conference machine via a wire, thereby establishing a power path and providing power support to the conference machine.
[0039] Please refer to Figures 1-5 The guide groove 301 is located at the edge of the battery mounting position at the bottom of the conference machine body. It is used to slide with the positioning sector post 302. The positioning sector post 302 is a cylindrical structure with a sector cross-section, which is used to insert into the guide groove 301 to achieve circumferential positioning.
[0040] The annular anti-slip rubber ring 303 is made of elastic rubber material and is embedded in the bottom surface of the conference machine body. The annular groove 304 is an annular groove with a depth that matches the height of the annular anti-slip rubber ring 303 for locking and fixing.
[0041] The magnetic pole distribution design of the first permanent magnet 102 and the second permanent magnet 202 is used to automatically attract and position the magnetic battery pack 2 when it is close to the bottom of the conference machine.
[0042] The elastic conductive sheet 203 is a spring-type contact with elastic deformation capability and is used to reduce insertion and removal wear; the power supply contact 103 is directly connected to the internal power circuit of the conference machine through a wire.
[0043] In this embodiment of the invention, as the battery pack approaches the bottom of the conference machine, the first permanent magnet 102 and the second permanent magnet 202 generate an interacting magnetic force based on their magnetic pole distribution design. Through a reasonable magnetic pole distribution, when the battery pack approaches, the magnetic force automatically attracts the battery pack to the main body connecting structure 1 and achieves automatic positioning, making the battery pack and the main body connecting structure 1 fit tightly together.
[0044] When installing a battery pack for the conference machine, first place the magnetic battery pack 2 along the direction of the guide groove 301 close to the battery mounting position at the bottom of the conference machine body. At this time, the positioning sector post 302 and the guide groove 301 begin to contact and slide together. Since the positioning sector post 302 is a cylindrical structure with a sector cross-section, the battery pack can be circumferentially positioned along the guide groove 301 during installation, ensuring the correct installation direction of the battery pack.
[0045] Meanwhile, the annular anti-slip rubber ring 303 on the bottom of the conference machine body cooperates with the annular groove 304 on the outer wall of the magnetic battery pack 2 housing. The annular anti-slip rubber ring 303 is made of elastic rubber material and has a certain degree of elasticity. When the battery pack is close, the annular anti-slip rubber ring 303 is embedded in the annular groove 304, further preventing the battery pack from shifting during the adsorption process, thereby avoiding poor contact problems caused by shifting.
[0046] After the battery pack is tightly connected to the main body connection structure 1, the elastic conductive sheet 203 comes into contact with the power supply contact 103. The elastic conductive sheet 203 has elastic deformation capability, generating a certain elastic pressure when in contact with the power supply contact 103, ensuring a good electrical connection while reducing wear on the contact during long-term insertion and removal. The power supply contact 103 is directly connected to the internal power circuit of the conference machine via a wire, thus establishing a power path and providing power support to the conference machine.
[0047] In addition, the built-in protection circuit 4 of the magnetic battery pack 2 plays an important role. The overvoltage protection module can monitor the output voltage of the battery pack and cut off the circuit in time when the voltage exceeds the set safety range to prevent overvoltage damage to the conference machine; the overcurrent protection module can act quickly when the current is too large to avoid safety hazards caused by overcurrent; the short circuit protection module can immediately disconnect the circuit when a short circuit fault occurs in the battery pack to ensure power supply safety.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
