Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle accessories, and particularly relates to a valve seat for a new energy electric vehicle with high air tightness. Background Technique

[0002] An electric vehicle uses a battery as a power source. During long-term use, the battery temperature is relatively high and heat dissipation is required. Otherwise, it will affect the battery life. For example, the patent number CN201010000605.2 discloses an efficient heat dissipation power battery, an electric vehicle temperature control system and an electric vehicle. This solution controls the inlet and outlet air states by connecting an air inlet pipe and an air outlet pipe to the battery box and installing valves on both the air outlet pipe and the air inlet pipe. The core components of the valve are the valve core and the valve seat. When in use, the valve core cooperates with the valve seat to control the ventilation state. Therefore, the connection air tightness between the valve core and the valve seat directly affects the air tightness of the valve. At present, when the valve core and the valve seat are in use, the valve core directly contacts the valve seat to achieve the closing and sealing of the valve. This connection method is not tight enough and cannot achieve the sealing protection between the valve core and the valve seat through an auxiliary protection structure, resulting in general air tightness of the valve. Therefore, improvement is needed. Content of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] Aiming at the deficiencies of the prior art, the utility model provides a valve seat for a new energy electric vehicle with high air tightness. By arranging equally spaced installation grooves at the bevel section of the valve seat, and arranging folding blocks at the installation grooves, the folding blocks are composed of a flipping seat, a baffle plate and a clamping plate. When the valve core contacts the valve seat, the valve core first contacts the baffle plate and then drives the flipping seat and the clamping plate to rotate, so that the sealing plate on one side of the clamping plate contacts the valve core, thereby strengthening the sealing relationship between the valve seat and the valve core, and solving the problem of poor sealing performance of the valve seat of the new energy electric vehicle at present.

[0005] (2) Technical Solutions

[0006] In order to achieve the above object, the utility model specifically adopts the following technical solutions:

[0007] A new energy electric vehicle valve seat with high airtightness, including a valve seat body. Two symmetrically distributed inclined cut surfaces are provided at the upper part of the valve seat body. Installation grooves are provided at equal distances at the inclined cut surfaces of the valve seat body, and folding blocks are arranged at the installation grooves of the valve seat body. The folding block includes a flipping seat adapted to the installation groove, a baffle plate and a clamping plate integrally formed on the flipping seat. A shaft rod is fixedly connected to the flipping seat, and the shaft rod is rotatably connected to a circular hole correspondingly arranged on the valve seat body. A torsion spring is fixedly connected to one side of the flipping seat, and the other side of the torsion spring is fixed on the valve seat body. When the valve core is adapted to the inner side of the valve seat body, the side of the valve core will contact the baffle plate, and then the flipping seat and the clamping plate will be folded, and the auxiliary sealing of the valve core is realized through the clamping plate.

[0008] Further, a fixed platform is formed on one side of the clamping plate, and a sealing plate is fixedly connected to the fixed platform of the clamping plate. One side of the sealing plate is in contact with the valve core.

[0009] Further, a sealing gasket is fixedly connected to the inclined cut surface of the valve seat body. The sealing gasket is in contact with the valve core, and a relief groove is provided at the sealing gasket corresponding to the installation groove.

[0010] Further, the contour of the baffle plate is consistent with that of the relief groove. When the valve core is closed to the valve seat body, the baffle plate rotates and fits inside the installation groove and the relief groove.

[0011] Further, an extension cavity is provided on one side of the valve seat body where the installation groove is located, and the torsion spring is located in the extension cavity.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Embodiment

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a high-airtightness new energy electric vehicle valve seat proposed in an embodiment of the present utility model includes a valve seat body 1. Two symmetrically distributed inclined planes are provided at the upper part of the valve seat body 1. Installation grooves 7 are provided at equal intervals at the inclined planes of the valve seat body 1. A folding block 5 is provided at the installation grooves 7 of the valve seat body 1. The folding block 5 includes a flipping seat 501 adapted to the installation groove 7, and a baffle plate 502 and a clamping plate 504 integrally formed on the flipping seat 501. A shaft rod 3 is fixedly connected to the flipping seat 501. The shaft rod 3 is rotatably connected to a corresponding round hole 9 on the valve seat body 1. A torsion spring 4 is fixedly connected to one side of the flipping seat 501. The other side of the torsion spring 4 is fixed on the valve seat body 1. When the valve core 11 is adapted to the inside of the valve seat body 1, the side part of the valve core 11 will contact the baffle plate 502, and then the flipping seat 501 and the clamping plate 504 will be folded, and the auxiliary sealing of the valve core 11 is realized through the clamping plate 504.

[0023] It should be noted that the valve seat body 1 is fixed inside the valve and cooperates with the valve core 11 to achieve the sealing of the valve. By providing an inclined cut surface at the upper part of the valve seat body 1, the contact surface between the valve seat body 1 and the valve core 11 can be increased, thereby enhancing the sealing effect. By providing equally spaced mounting grooves 7 at the inclined cut surface of the valve seat body 1, the mounting grooves 7 are used for the installation of the folding blocks 5. The folding block 5 is composed of a flipping seat 501, a baffle 502, and a clamping plate 504. Among them, a shaft rod 3 is fixedly connected to the flipping seat 501, and the shaft rod 3 is rotatably connected to the circular hole 9 of the valve seat body 1, enabling the synchronous flipping of multiple folding blocks 5. When the valve core 11 is connected to the valve seat body 1, it will first contact the baffle 502. When the baffle 502 rotates, the clamping plate 504 rotates, and then the side of the valve core 11 is assisted to be clamped through the clamping plate 504, thereby increasing the tightness of the cooperation between the valve seat body 1 and the valve core 11. This method can increase the airtight performance of the connection between the valve seat body 1 and the valve core 11, prevent leakage, and is suitable for use in the field of new energy electric vehicles.

[0024] As Figure 1 , Figure 3 and Figure 4 shown, in some embodiments, a fixed platform 503 is formed on one side of the clamping plate 504, and a sealing plate 6 is fixedly connected to the fixed platform 503 of the clamping plate 504. One side of the sealing plate 6 is in contact with the valve core 11.

[0025] It should be noted that the fixed platform 503 is provided for the installation and fixation of the sealing plate 6. By fixedly connecting the sealing plate 6 to one side of the clamping plate 504, when the clamping plate 504 flips, the sealing plate 6 can be brought into contact with the side of the valve core 11, thereby increasing the sealing performance between the valve core 11 and the valve seat body 1 through the sealing plate 6.

[0026] As Figure 1 , Figure 2 and Figure 4 shown, in some embodiments, a sealing gasket 2 is fixedly connected to the inclined cut surface of the valve seat body 1. The sealing gasket 2 is in contact with the valve core 11, and a relief groove 8 is provided at the position of the sealing gasket 2 corresponding to the mounting groove 7.

[0027] It should be noted that the setting of the sealing gasket 2 can increase the tightness of the connection between the valve seat body 1 and the valve core 11. By providing the relief groove 8 on the sealing gasket 2, it is convenient for the rotation of the baffle 502.

[0028] As Figure 1 , Figure 2 and Figure 3 shown, in some embodiments, the contour of the baffle 502 is consistent with the relief groove 8. When the valve core 11 closes to the valve seat body 1, the baffle 502 rotates and fits inside the mounting groove 7 and the relief groove 8.

[0029] It should be noted that when the valve core 11 moves towards the valve seat body 1, and then the baffle 502 rotates, the baffle 502 can be closed to the installation groove 7 and the relief groove 8, realizing the tight connection between the valve core 11 and the gasket 2.

[0030] As Figure 1 and Figure 2 shown, in some embodiments, the valve seat body 1 is provided with an extension cavity 10 on one side of the installation groove 7, and the torsion spring 4 is located at the extension cavity 10.

[0031] It should be noted that the setting of the extension cavity 10 can form an installation space for accommodating and installing the torsion spring 4. The setting of the torsion spring 4 can form an automatic reset function for the folding block 5. When the valve core 11 leaves the valve seat body 1, the folding block 5 can reset itself.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
