Technical Field
[0001] This utility model relates to a transducer, and more particularly to a transducer for a vehicle designed to prevent blockage. Background Technology
[0002] Many vehicles, such as motorcycles, have passengers whose seating is exposed to the outside. These vehicles often face the problem of seats being cold in winter and hot in summer. Multi-wheeled vehicles, such as cars, also face the same problem.
[0003] Many existing solutions involve adding cooling or heating to parts such as seat cushions and backrests. In the applicant's previous Chinese invention patent application 202411893264.4, a transducer was used to transfer heat. However, such a transducer has certain defects.
[0004] If blockages are prone to occur, especially when used in motorcycles, the existing transducers are prone to blockages due to the human body transferring more pressure to the transducers. This not only affects the heat exchange efficiency but also poses a safety hazard. Moreover, the current technology, which relies solely on pipes to conduct heat, suffers from reduced efficiency.

[0025] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0026] Example
[0027] like Figure 1-5As shown, this embodiment provides a transducer for a vehicle that prevents blockage. Its body 000 is connected to the heat exchange mechanism 100. The body 000 includes a first gasket 200 and a second gasket 300.
[0028] The second gasket 300 has a protruding tube 400, wherein the cavity portion 403 of the protruding tube 400 has an anti-clogging mechanism 4031. Specifically, regarding the connection form between the protruding tube 400 and the second gasket 300, the protruding tube 400 may be composite or bonded to the second gasket 300, or the protruding tube 400 and the second gasket 300 may be integrally formed; the protruding tube 400 is formed on the second gasket 300, and its cavity portion 403 contains an elliptical anti-clogging mechanism 4031; when fluid enters the cavity portion 403 from the first connector 401, under pressure, the major axis of the elliptical anti-clogging mechanism 4031 is aligned with... The protruding tube 400 always maintains a gap between its walls to allow liquid to pass through, preventing the cavity from being completely blocked. This ensures that the fluid can flow smoothly and complete heat exchange under any extrusion or deformation conditions. The protruding tube 400 can be firmly bonded to the second gasket 300 by composite or adhesive methods, or it can be formed integrally with the second gasket 300. Regardless of the connection method used, the protruding tube 400 and the second gasket 300 maintain a continuous and stable structure, ensuring that heat is efficiently transferred along the path of second gasket 300—protruding tube 400—anti-blocking mechanism 4031—fluid, and continues to play a role during fluid circulation.
[0029] The anti-blocking mechanism 4031 is located between the second gasket 300 and the wall of the protruding tube 400. In this embodiment, the cross-section of the anti-blocking mechanism 4031 includes elliptical, polygonal, etc. When the protruding tube 400 is squeezed, the elliptical cross-section can prevent the protruding tube 400 from being completely blocked, thus preventing the fluid from passing through for heat exchange.
[0030] The anti-blocking mechanism 4031 is firmly clamped between the second gasket 300 and the wall of the protruding tube 400, and its cross-section is elliptical or polygonal. When the weight of the occupant causes the second gasket 300 to be compressed and the protruding tube 400 to be flattened, the major axis of the ellipse or the apex of the polygon of the anti-blocking mechanism 4031 presses against the tube wall to prevent the tube cavity from being completely closed. A smooth gap is always maintained between the tube wall and the anti-blocking mechanism 4031, allowing the fluid to continuously pass through the cavity 403 and complete the heat exchange, thereby ensuring that the heat exchange process remains efficient and uninterrupted no matter how much external force squeezes it.
[0031] Preferably, in this embodiment, the two sides of the protruding tube 400 have a receiving portion 404 formed by grooves, and a heat-conducting foil, preferably copper foil, is installed in the receiving portion 404 to assist in heat conduction and improve processing efficiency; in another embodiment of this utility model, when the first gasket 200 and the second gasket 300 are welded together, the receiving portion 404 is formed, and the anti-blocking mechanism 4031 is formed in the cavity portion 403.
[0032] In another embodiment of this utility model, the first pad 200 is preferably a heat sink such as aluminum foil or copper foil, and the second pad 300 and the protruding tube 400 are preferably made of TPU material. When the fluid in the protruding tube 400 is in contact with the first pad 200, heat dissipation is achieved.
[0033] Specifically, during operation, the first pad 200, made of aluminum or copper foil, is in close contact with the surface of the seat cushion, acting as a high-efficiency heat sink. When the TPU protrusion tube 400 is filled with fluid driven by the heat exchange mechanism 100, the liquid flows directly into large-area contact with the inner side of the first pad 200 as it flows in the cavity 403. Heat or cold energy is rapidly diffused outward through the high thermal conductivity of the metal foil, achieving rapid heat dissipation or cooling. At the same time, the second TPU pad 300 is integrally or compositely connected with the protrusion tube 400. Its flexibility allows the overall structure to maintain elastic recovery under repeated pressure, ensuring that the liquid continues to be in full contact with the first pad 200, thereby continuously completing efficient heat exchange throughout the entire cycle.
[0034] The main body 000 is connected to the first pipe 101 and the second pipe 102 of the heat exchange mechanism 100. Specifically, the two ends of the protruding pipe 400 are respectively formed with a first connector 401 and a second connector 402. The first connector 401 and the second connector 402 are connected to the first pipe 101 and the second pipe 102 of the heat exchange mechanism 100. The heat exchange mechanism 100 can circulate fluid with the protruding pipe 400 of the main body 000 to achieve heat conduction.
[0035] After the vehicle starts, the fluid inside the heat exchange mechanism 100 is driven to flow through the first pipe 101 to the first connector 401, and then enters the cavity 403 of the protruding tube 400. Because the anti-blocking mechanism 4031 has an elliptical cross-section and is located between the second gasket 300 and the wall of the protruding tube 400, the fluid flows smoothly along the gap formed by the major axis of the ellipse and the tube wall. During its journey, it fully contacts the second gasket 300, the first gasket 200, and the heat-conducting foil pre-placed in the receiving part 404, achieving the first exchange of heat or cold. The fluid then continues to the second connector 402, returns to the heat exchange mechanism 100 through the second pipe 102, completing a closed loop, and is then re-temperature-regulated before being sent out again through the first pipe 101, repeating this process continuously. When the passenger sits down, the second gasket 300 is deformed by pressure, and the protruding tube 400 is squeezed. At this time, the elliptical anti-blocking mechanism 4031... The short axis of 031 is compressed while the long axis expands outward, ensuring that a gap is always maintained between the pipe wall and the anti-blocking mechanism 4031, allowing fluid to pass through and preventing blockage. This ensures that the fluid remains unobstructed during the compression-relaxation-re-compression cycle. Simultaneously, the heat-conducting foil adheres tightly to the second gasket 300, rapidly diffusing the heat or cold carried by the fluid in the protruding tube 400 laterally to the first gasket 200, and then evenly transferring it to the seat surface from the first gasket 200. If the protruding tube 400 and the second gasket 300 are integrally formed, there is no interface thermal resistance between them, resulting in more direct heat exchange. If they are a composite connection, a high thermal conductivity adhesive layer ensures continuous heat transfer. Throughout the process, the first connector 401 and the second connector 402 are always sealed to the first pipe 101 and the second pipe 102 of the heat exchange mechanism 100, ensuring that the fluid will not leak or block heat dissipation under any driving conditions.
[0036] This invention features an anti-blocking mechanism 4031 formed inside the protruding tube 400. When the protruding tube 400 is squeezed, a gap is formed between the tube and the anti-blocking mechanism, allowing fluid to pass through. This allows for unimpeded heat exchange or energy exchange without affecting the heat exchange efficiency. A receiving portion is provided on the side of the protruding tube, which can hold heat-conducting foil to assist in energy exchange and improve efficiency. Throughout the entire operation, the main body 000, through the first joint 401 and the second joint 402 integrally formed at both ends of the protruding tube 400, forms a sealed connection with the first pipe 101 and the second pipe 102 of the heat exchange mechanism 100, respectively. When the heat exchange mechanism 100 is started, the temperature-regulated fluid flows out from the first pipe 101, enters the cavity 403 of the protruding tube 400 through the first joint 401, absorbs or releases heat along the tube, continues to flow to the second joint 402, and then returns to the heat exchange mechanism 100 through the second pipe 102, thus forming a closed loop. With the help of this continuous loop, heat is constantly transferred between the heat exchange mechanism 100 and the main body 000, realizing continuous heat conduction and temperature regulation of the seat surface. The first joint 401 and the second joint 402 always maintain a reliable connection, ensuring that the fluid can stably reciprocate under any driving conditions and complete efficient heat exchange.
