Description

Technical Field

[0001] The invention belongs to the technical field of tricycle parts, and in particular relates to a tricycle radiator water tank safety cover and a radiator water tank with the safety cover. Background Art

[0002] The radiator is a crucial component on a three-wheeled motorcycle, used to provide circulating cooling water to the radiator. It's an essential part of any tricycle. A common radiator structure, such as the one in Patent No. 201410735555.0, titled "A Circulating Radiator and Shield Assembly for a Three-Wheeled Vehicle," is known for its ability to heat the coolant while the radiator is in motion. If the radiator doesn't dissipate heat promptly, the coolant's temperature will continue to rise, generating large amounts of steam inside the radiator. This directly increases the internal pressure. If the pressure isn't released promptly, it could result in an accident involving excessive pressure and steam erupting, potentially causing injuries. This creates a relatively low safety risk.

[0003] Therefore, a pressure-reducing vent nozzle is provided on a traditional water tank, and a hole structure connected to the outside is provided directly on the top of the water tank to avoid the accumulation of pressure inside the water tank. However, the applicant found in the research that the open pressure-reducing vent nozzle structure will cause the internal coolant to be consumed faster, and it is also susceptible to external contamination, which reduces the reliability of the cooling system and may shorten its service life. Summary of the Invention

[0004] In view of this, the present invention provides a tricycle radiator water tank safety cover and a radiator water tank with the safety cover, so as to solve the problem that the existing tricycle radiator water tank high temperature pressure boosting cannot be well solved.

[0005] The technical solution is as follows:

[0006] A safety cover for a radiator water tank of a tricycle, the key features of which are: a cover body with a hollow structure, the bottom of which is open and has a connecting structure A, a pressure separation structure within the cover body, which divides the internal space of the cover body into a lower chamber and an upper chamber, and a pressure relief channel in communication with the upper chamber on the cover body;

[0007] Under normal pressure, the pressure separation structure can seal the lower chamber. When the pressure in the lower chamber exceeds a preset value, the lower chamber and the upper chamber can be connected through the pressure separation structure to relieve pressure.

[0008] By adopting the above solution, by setting up a pressure separation structure, it can not only meet the sealing effect on the inside of the water tank under normal pressure, reduce the consumption of coolant, prevent or reduce the contamination of coolant, and ensure its performance reliability and stability, but also meet the pressure relief requirements under high temperature conditions, avoid excessive internal pressure, and reduce safety risks, that is, take into account both the sealing and safety of the cooling system.

[0009] Preferably, the pressure separation structure includes a separation plate and a sealing ball. The separation plate has a downwardly tapered upper surface, with a pressure relief hole at its lowest point connecting the lower and upper chambers. The sealing ball has a larger diameter than the pressure relief hole. This solution, combining the floating ball principle and the dual mechanism of pressure differential release, achieves rapid response under different operating conditions, a simple structure, and extremely low implementation costs.

[0010] Preferably, a retaining structure is provided on the partition plate and / or the cover at the position corresponding to the pressure relief hole. This retaining structure ensures that the sealing ball maintains its seal against the pressure relief hole at room temperature. This solution improves operational reliability, ensuring that the pressure relief hole remains sealed at normal pressure even if the installation position is slightly tilted or the vehicle body is tilted, minimizing the impact of ambient conditions on the sealing effect.

[0011] Preferably, the position-limiting structure is a recessed groove provided on the partition plate, the minimum diameter of the recessed groove being larger than the diameter of the sealing ball; the pressure relief hole and the recessed groove are both circular in cross-section and coaxially arranged. Using the recessed groove to limit the approximate position of the sealing ball can further reduce implementation costs.

[0012] Preferably, the diameter of the trough gradually decreases as it approaches the lower chamber. With the above solution, the blocking balls can enter the trough more easily, and the smaller bottom space can limit the blocking balls and reduce the impact of driving shaking.

[0013] As a preferred embodiment, the bottom of the partition plate corresponding to the sink groove is an arc-shaped structure. The above solution can reduce the impact of pressure shock, prevent the position from becoming a weak point, and extend the service life.

[0014] Preferably, the cover body is a split structure, including an upper cover and a lower cover, which are sealed and connected. With the above solution, the split structure is more convenient for processing or installation of the pressure separation structure, and is also convenient for subsequent disassembly and maintenance.

[0015] As a preferred embodiment, the partition plate is integrally formed with the lower cover. The above solution further improves reliability, reduces later assembly processes, reduces production and assembly costs, and also avoids errors introduced by assembly.

[0016] Preferably, the upper portion of the lower cover has a diameter-reduced section, and the partition plate is located at the top of the diameter-reduced section.

[0017] Based on the above tricycle radiator water tank safety cover, this application also proposes a radiator water tank to improve the safety and reliability of the radiator water tank. The technical solution is as follows:

[0018] A heat dissipation water tank comprises a box body, and the key point is that the box body is equipped with the above-mentioned tricycle heat dissipation water tank safety cover.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The radiator water tank safety cover and the radiator water tank with the safety cover provided by the present invention can seal the water tank when the coolant is within a normal temperature and pressure range during normal driving, effectively preventing coolant from splashing out due to vehicle bumps, vibrations or tilts, thereby ensuring the stability and sealing of the cooling system.

[0021] Under high temperature and high pressure conditions, that is, when the coolant generates a large amount of steam inside the water tank due to high temperature operation, and the internal pressure suddenly increases to the set threshold, the water vapor pressure opens the pressure relief channel through the pressure separation structure, allowing the steam to be discharged in a direction. This process can achieve automatic pressure relief protection without opening the water tank cover, effectively preventing water vapor eruptions caused by excessive pressure and injuring people, thereby improving the safety of system operation.

[0022] As the temperature drops and the pressure drops, the pressure separation structure resets and re-establishes an airtight seal, protecting the cooling system from external contamination while also enabling self-reset capability without manual intervention. The overall structure is ingeniously designed and easy to implement. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be described in further detail below with reference to the accompanying drawings.

[0032] refer to Figures 1 to 8The tricycle radiator water tank safety cover and the radiator water tank with the safety cover are shown, wherein the tricycle radiator water tank safety cover mainly includes a cover body 1 with a hollow structure, the bottom of the cover body 1 is open and has a connecting structure A2, the cover body 1 has a pressure separation structure, the pressure separation structure divides the internal space of the cover body 1 into a lower chamber 10 and an upper chamber 11, and the cover body 1 has a pressure relief channel 3 connected to the upper chamber 11.

[0033] The pressure separation structure in this application has two forms. One is a sealed state, that is, under normal pressure, the pressure separation structure can seal the lower chamber 10. The other is a pressure relief state. When the pressure in the lower chamber 10 exceeds the preset value, the lower chamber 10 and the upper chamber 11 can be connected through the pressure separation structure, and then connected to the external environment through the pressure relief channel 3, thereby realizing internal pressure relief.

[0034] In an embodiment given in the present application, the pressure separation structure includes a partition plate 4 and a sealing ball 5. The upper surface of the partition plate 4 is a downward conical surface, and a pressure relief hole 40 connecting the lower chamber 10 and the upper chamber 11 is provided at its lowest point. It is roughly funnel-shaped. The diameter of the sealing ball 5 is larger than the diameter of the pressure relief hole 40. The sealing ball 5 is made of conventional glass balls. Under normal pressure, when the sealing ball 5 is located on the partition plate 4, it can seal the pressure relief hole 40 under the action of its own weight. When the pressure in the lower chamber 10 increases until its thrust exceeds the sealing ball 5, the sealing ball 5 can be pushed away, and the lower chamber 10 and the upper chamber 11 are instantly connected through the pressure relief hole 40, and then the steam in the lower chamber 10 can be discharged through the pressure relief channel 3 to achieve pressure relief. The preset pressure value here corresponds to the weight of the selected sealing ball 5.

[0035] After the pressure in the lower chamber 10 drops, the sealing ball 5 slides to the lowest point along the conical surface and re-seals the pressure relief hole 40. In order to prevent the sealing ball 5 from deviating from the sealing position due to bumps and vibrations during driving, a limiting retaining structure is provided at the position corresponding to the pressure relief hole 40 on the partition plate 4 or / and the cover body 1 in this application. It should be noted that the limiting retaining structure can be set separately on the partition plate 4 or separately on the cover body 1, or it can be a matching structure on the partition plate 4 and the cover body 1, which is mainly used to enable the sealing ball 5 to maintain the sealing of the pressure relief hole 40 under normal driving conditions at room temperature.

[0036] In this embodiment, the retaining structure is a recessed groove 41 provided on the partition plate 4. The recessed groove 41 can be circular or polygonal, with a minimum diameter larger than the diameter of the sealing ball 5 to ensure that the sealing ball 5 can properly engage and seal the upper end of the pressure relief hole 40. In practice, both the pressure relief hole 40 and the recessed groove 41 are circular in cross-section and are coaxially arranged. The diameter of the recessed groove 41 gradually decreases as it approaches the lower chamber 10.

[0037] In addition, in this embodiment, the bottom of the partition plate 4 corresponding to the sink 41 is an arc-shaped structure.

[0038] In addition to the above-mentioned groove 41 structure, the limiting and retaining structure can also adopt a cylindrical structure, that is, a hollow sleeve is set corresponding to the pressure relief hole 40, and the sleeve extends and leans against the top of the cover body. The gap between the two is smaller than the diameter of the sealing ball 5, and the hollow gap is also smaller than the diameter of the sealing ball 5. This ensures that the sealing ball 5 can seal the pressure relief hole.

[0039] On this basis, a spring can be set in the sleeve, and the upper end of the spring is fixed to the top of the cover body. In this way, not only can the weight of the sealing ball be selected according to needs, but also the opening pressure value can be preset by selecting springs with different elastic coefficients or lengths to meet the use requirements of more air pressure environments.

[0040] In another embodiment given in the present application, the pressure separation structure sealing ball 5 is a sealing plate, which can be installed on the partition plate 4 through a torsion spring. The sealing plate seals the pressure relief hole 40 under the action of the torsion spring. When the pressure rises in the lower chamber 10 and can overcome the elastic force of the torsion spring, the sealing plate is pushed open, thereby achieving instantaneous pressure relief.

[0041] In a specific implementation, the side of the sealing sheet corresponding to the lower chamber 10 has a plug adapted to the pressure relief hole 40 . The plug is generally spherical and can be embedded in the pressure relief hole 40 to improve the sealing effect.

[0042] In the present application, in order to improve processing and assembly efficiency and reduce production difficulty, the cover body 1 is a split structure, including an upper cover 13 and a lower cover 14. The upper cover 13 and the lower cover 14 are sealed and connected. Specifically, the upper part of the lower cover 14 has a reduced diameter section 15, and the upper cover 13 is buckled on the reduced diameter section 15, and the two are interference fit.

[0043] As shown in the figure, the upper cover 13 and the lower cover 14 are both injection molded parts, with an annular protrusion 12 on the reduced diameter section 15, and an annular groove 16 on the inner side of the upper cover 13 that cooperates with the annular protrusion 12. In addition, the outer side of the reduced diameter section 15 also has a vertical protrusion 17 arranged along its length direction. Correspondingly, the upper cover 13 has a strip groove 18 that cooperates with the vertical protrusion 17. During installation, the strip groove 18 on the upper cover 13 is pressed and fastened onto 14 after facing the vertical protrusion 17. The annular protrusion 12 cooperates with the annular groove 16 to achieve axial relative fixation of the two, and the vertical protrusion 17 cooperates with the strip groove 18 to achieve circumferential relative fixation of the two.

[0044] Based on the above split structure, in this embodiment, the partition plate 4 and the lower cover 14 are formed as one piece, and the partition plate 4 is located at the top of the reduced diameter section 15 .

[0045] In this embodiment, the pressure relief channel 3 is an extension tube connected to the upper chamber 11 and is arranged along the radial direction of the upper chamber 11. In addition, it can also be a through-hole structure directly arranged on the upper cover 13. Relatively speaking, in this embodiment, the pressure relief from the side through the extension tube can greatly reduce the risk, avoid safety accidents caused by steam upward, and at the same time reduce the impact of air pressure on the upper cover 13.

[0046] Based on the tricycle radiator water tank safety cover, this application also simultaneously proposes to protect a radiator water tank. As shown in the figure, the radiator water tank mainly includes a box body A and a shield B, and the tricycle radiator water tank safety cover is installed on the box body A. The connection structure A2 is an internal thread structure. The box body A has a pressure relief interface C, and the cover body 1 is threadedly matched with the pressure relief interface C.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
