Description

Technical Field

[0001] The utility model relates to the technical field of electronic components, in particular to a dual-channel switching switch. Background Art

[0002] A dual-channel transfer switch is a device used to automatically or manually switch between two power or signal paths. This type of switch is commonly used in systems requiring high reliability and continuous power or signal transmission, such as power supply, communications equipment, and industrial control. The primary function of a dual-channel transfer switch is to ensure rapid and smooth switching to a backup power or signal path in the event of a failure in the primary power or signal path, thereby ensuring continued system operation. It can also be used as an electronic component that directly converts rotational angle displacement into a digital signal.

[0003] Existing dual-channel switches typically utilize a one-piece plastic design. This design presents challenges in dimensional control, resulting in a loose or tight connection between the external shaft and the rotor, leading to a high rate of production defects. Furthermore, rigid materials are prone to noise and misaligned connections, impacting user experience and device lifespan. Summary of the Invention

[0004] The purpose of the utility model is to overcome the defects and shortcomings of the prior art and provide a dual-channel switching switch. The dual-channel switching switch solves the problems of size control and installation and assembly by adopting a rotor made of flexible material, reduces the production defect rate, and at the same time, the adaptive adjustment ability and good elastic properties of the flexible material play a role in buffering and vibration isolation, improves the stability and comfort when using the device, and enhances the user experience and service life of the device.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A dual-channel switch includes a base and a housing, wherein the base and the housing are connected to form an accommodating space, and a conductive code disk, a conductive brush, and a rotor are sequentially arranged in the accommodating space from bottom to top;

[0007] The conductive code disk is embedded in the base;

[0008] The conductive brush contacts and cooperates with the conductive code disc and is transmission-connected to the rotor;

[0009] The rotor is made of a flexible material and is used for connecting with an external rotating shaft for transmission.

[0010] As a preference, the flexible material is silicone, rubber, latex or nitrile rubber.

[0011] As a preference, a plurality of elastic support members are provided inside the rotor, and the plurality of elastic support members are evenly distributed inside the rotor to provide elastic support when a slight displacement or vibration occurs to the external rotating shaft.

[0012] Preferably, the elastic support member is a spring, an elastomer or an airbag.

[0013] As a preference, the surface of the rotor is provided with textures for increasing the friction between the rotor and the external shaft.

[0014] As a preferred embodiment, it further comprises a positioning ring and a positioning piece, wherein the positioning ring is drivingly connected to the rotor, and the positioning piece is connected to the base;

[0015] The positioning ring is provided with a first clamping structure, which is distributed in a circle with the axis of the positioning ring as the center. The positioning plate is provided with a second clamping structure. When the positioning ring rotates relative to the positioning plate, at least one of the positioning plate and the positioning ring can be elastically deformed so that the first clamping structure can be detachably clamped with the second clamping structure to provide tactile feedback.

[0016] Preferably, one of the first clamping structure and the second clamping structure is a protrusion, and the other of the first clamping structure and the second clamping structure is a groove, and when the positioning ring rotates relative to the positioning plate, the protrusion can be engaged with and disengaged from the groove.

[0017] As a preference, a positioning column is provided on the base, and a positioning hole is provided on the positioning piece, and the positioning column cooperates with the positioning hole to limit the relative movement between the positioning piece and the base.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] 1. The flexible rotor has excellent elasticity and scalability, enabling adaptive adjustment to minor displacements or vibrations of the external shaft, maintaining a stable transmission connection. This ensures high stability across the entire device under various operating conditions. Compared to existing integrated plastic products, the flexible rotor of this utility model, through its elastic properties, can better adapt to dimensional changes in the external shaft, offering greater flexibility in dimensional control and enabling the external shaft to tilt and swing within 3° when tightly assembled. This flexibility allows the device to adapt to diverse installation conditions and operating environments, increasing its range of applications and practicality.

[0020] 2. The flexible rotor is able to integrate more tightly with the external shaft, significantly reducing the noise generated by rotation, vibration, and shaking. This tight integration ensures smoother and quieter operation, improving the user experience.

[0021] 3. Because the flexible rotor can better adapt to the dimensional changes of the external shaft, it reduces assembly problems caused by size mismatch, thereby improving production efficiency and product quality. This not only reduces production costs but also improves the market competitiveness of the product.

[0022] 4. Multiple evenly distributed elastic supports are located inside the rotor to provide elastic support when the external shaft undergoes slight displacement or vibration. This enables the rotor to adaptively adjust its shape, further ensuring a stable transmission connection under various operating conditions.

[0023] 5. The elastic support member can be a spring, an elastomer or an airbag. These different types of elastic support members provide a variety of options to meet different application requirements.

[0024] 6. Textured rotor surfaces increase the contact area between the rotor and the external shaft, thereby increasing friction, preventing slippage and further improving transmission stability. This helps maintain reliable transmission under high loads or high speeds.

[0025] 7. The design of the positioning ring and the positioning piece provides clear tactile feedback. When the positioning ring rotates relative to the positioning piece, at least one of the positioning piece and the positioning ring can elastically deform, allowing the first engaging structure to detachably engage with the second engaging structure, providing a clear operational feel.

[0035] The present invention will be described in further detail below with reference to the embodiments and drawings, but the embodiments of the present invention are not limited thereto.

[0036] like Figure 1 As shown, a dual-channel switch includes a base and a housing, wherein the base is connected to the housing to form an accommodating space, and a conductive code disk, a conductive brush, and a rotor are sequentially arranged in the accommodating space from bottom to top;

[0037] like Figure 2 As shown, the conductive code disk is embedded in the base, and the conductive code disk includes contact pins A, B and C. The contact pins A, B and C are used to contact and cooperate with the conductive brush to realize circuit switching.

[0038] The conductive brush contacts and cooperates with the conductive code disk and is transmission-connected to the rotor, ensuring that the circuit can be switched when the rotor rotates.

[0039] The rotor is made of a flexible material, such as silicone, rubber, latex or nitrile rubber, and is used to connect to the external rotating shaft for transmission. A connecting hole is provided on the rotor, and the connecting hole is a regular hexagonal hole. The rotor made of flexible material can be tightly combined with the external rotating shaft through the connecting hole, reducing the noise generated by rotation, vibration and shaking, and supporting the external rotating shaft to achieve a 3° angular deflection when tightly combined.

[0040] A plurality of elastic support members are provided inside the rotor, and the plurality of elastic support members are evenly distributed inside the rotor, and provide elastic support when a small displacement or vibration occurs to the external shaft, thereby maintaining close contact between the rotor and the external shaft.

[0041] The elastic support member is a spring, an elastomer or an air bag. The spring can be a coil spring or a disc spring. The elastomer can be a rubber block with high elasticity.

[0042] In order to increase the friction between the rotor and the external rotating shaft, prevent sliding and improve transmission stability, the surface of the rotor is provided with textures to increase the contact area between the rotor and the external rotating shaft.

[0043] It also includes a positioning ring and a positioning piece, wherein the positioning ring is transmission-connected to the rotor, and the positioning piece is connected to the base.

[0044] like Figure 6 and Figure 8 As shown, a first clamping structure is provided on the positioning ring, and the first clamping structure is distributed in a circle with the axis of the positioning ring as the center. A second clamping structure is provided on the positioning plate. When the positioning ring rotates relative to the positioning plate, at least one of the positioning plate and the positioning ring can be elastically deformed, so that the first clamping structure can be detachably clamped with the second clamping structure to provide tactile feedback.

[0045] One of the first and second clamping structures is a protrusion, and the other of the first and second clamping structures is a groove. When the positioning ring rotates relative to the positioning plate, the protrusion can be engaged with and disengaged from the groove, thereby providing clear tactile feedback.

[0046] like Figure 2 and Figure 7 As shown, a positioning column is provided on the base, and a positioning hole is provided on the positioning piece. The positioning column cooperates with the positioning hole to limit the relative movement between the positioning piece and the base.

[0047] like Figure 4 、 Figure 5 and Figure 7 As shown, a limiting column is provided on the positioning ring, a connecting boss is provided at the bottom of the rotor, a first limiting hole is provided on the connecting boss, a second limiting hole is provided on the conductive brush, and the limiting column passes through the first limiting hole and cooperates with the second limiting hole to limit the relative movement between the positioning ring and the rotor, and between the rotor and the conductive brush.

[0048] The positioning ring is provided with a limiting groove, and the connecting boss is provided with a limiting block. The limiting groove cooperates with the limiting block to further limit the relative movement between the positioning ring and the rotor.

[0049] The working principle of this utility model:

[0050] The external rotating shaft passes through the outer shell and is inserted into the rotor for rotation. The rotor, through the cooperation of the limiting post and the second limiting hole, drives the conductive brush to rotate clockwise or counterclockwise. The brush of the conductive brush contacts the conductive code disk. When the conductive brush contacts contact pins A and C simultaneously, contact pins A and C are connected; when the conductive brush contacts contact pins B and C simultaneously, contact pins B and C are connected. When the external rotating shaft continues to rotate, contact pins A and C, and contact pins B and C are alternately connected and disconnected, realizing the function of a dual-channel switch. The rotor, through the cooperation of the limiting post and the first limiting hole, the limiting slot and the limiting block, drives the positioning ring to rotate clockwise or counterclockwise. The protrusion on the positioning plate engages with the groove on the positioning ring. When the external rotating shaft continues to rotate, the protrusion moves from one groove to the other, producing a jumping feeling, thereby realizing the function of tactile feedback.

[0051] The assembly method of the dual-channel switch in this embodiment is as follows:

[0052] Insert the conductive code disc into the base, ensuring that contact pins A, B, and C are correctly aligned and fixed;

[0053] Install the rotor into the inner cavity of the positioning ring, and make the limiting post fit with the first limiting hole, the limiting groove and the limiting block, then install the conductive brush into the inner cavity of the positioning ring, and make the limiting post fit with the second limiting hole to form a combination of the positioning ring, the rotor and the conductive brush;

[0054] Place the assembly of the positioning ring, rotor and conductive brush on the conductive code disk, ensuring that the conductive brush contacts the contact pins A, B and C of the conductive code disk;

[0055] Install the positioning piece on the base, insert the positioning column into the positioning hole, and make the positioning column fit with the positioning hole;

[0056] Connect the housing to the base.

[0057] In addition to the methods mentioned in the above embodiments, the positioning ring and the rotor, and the rotor and the conductive brush can also be fixed by riveting, interlocking, bonding, hot melting or interference fit. These alternative methods are all within the scope of protection of the present utility model.

[0058] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
