Description

Technical Field

[0001] This utility model belongs to the field of air conditioning valve body technology, specifically an automotive air conditioning balance valve seat. Background Technology

[0002] In automotive air conditioning systems, the balance valve plays a crucial role, effectively distributing airflow, resolving uneven heating and cooling, and ensuring stable system operation. However, vehicles encounter various complex conditions during operation, such as bumps, vibrations, acceleration, and deceleration, which subject the balance valve to significant external impacts and vibrations.

[0003] Traditional automotive air conditioning balance valve installation methods are often quite simple, relying solely on basic connection structures to fix the balance valve in its position. This method of fixing is prone to loosening during long-term use, especially under frequent vibrations and impacts. Once the balance valve loosens, the seal between it and the connecting pipes deteriorates, leading to refrigerant leakage. It can also cause a decline in the performance of the entire automotive air conditioning system, increasing energy consumption and raising operating costs.

[0004] Therefore, in order to ensure that the automotive air conditioning balance valve can work stably and reliably under complex driving conditions, extend its service life, and reduce refrigerant leakage and system failure, it is essential to reinforce and secure the automotive air conditioning balance valve. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an automotive air conditioning balance valve seat, which reliably reinforces the automotive air conditioning balance valve, ensuring its stable and reliable operation under complex driving conditions, improving its service life, and reducing refrigerant leakage and system failure.

[0006] This utility model provides the following technical solution: an automotive air conditioning balance valve seat, including a balance valve body, a valve stem at the top of the balance valve body, a connecting seat attached to the bottom of the balance valve body, and arc-shaped hanging rings hinged to both sides of the rear of the connecting seat. The inner surface of the arc-shaped hanging rings is attached to the top of the balance valve body, and the front end of the arc-shaped hanging rings is fixedly connected to the top of the connecting seat by bolts. Synchronous connecting plates are fixedly connected to the front and rear sides of the two arc-shaped hanging rings on opposite sides. A clamping and locking structure is provided at the top of the arc-shaped hanging rings. The output end of the clamping and locking structure is attached to the surface of the valve stem for fixing the valve stem. A mounting plate is provided at the bottom of the connecting seat, and a spacing adjustment mechanism is provided between the connecting seat and the mounting plate for adjusting the installation spacing.

[0007] The clamping and locking structure includes two symmetrically arranged movable plates. The bottom of the movable plates is slidably connected to the top of the arc-shaped hanging ring. An arc-shaped clamp is fixedly connected to the inner side of the movable plates. The inner side of the arc-shaped clamp is in contact with the surface of the valve stem. A nut seat is fixedly connected to the top of the movable plates. A two-way lead screw is threaded into the nut seat.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model features a bottom-fitting connecting seat for the balance valve body, with hinged arc-shaped hanging rings on both rear sides of the connecting seat. The front ends of the arc-shaped hanging rings are fixed to the top of the connecting seat with bolts, ensuring the balance valve body is securely fixed to the connecting seat and preventing loosening or displacement during vehicle vibrations. Simultaneously, synchronous connecting plates are fixedly connected to the front and rear sides of opposite sides of the two arc-shaped hanging rings, ensuring the synchronicity of their movements and further enhancing stability. The clamping and locking structure at the top of the arc-shaped hanging rings secures the valve stem, preventing valve stem wobbling from affecting the normal operation of the balance valve. A mounting plate is located at the bottom of the connecting seat, and the mounting feet at the four corners of the mounting plate can be fixed with corresponding threaded holes in the vehicle's engine compartment using bolts, achieving reliable installation of the balance valve seat within the engine compartment. The adjustable spacing mechanism between the connecting seat and the mounting plate allows for adjustment of the installation spacing, adapting to different vehicle engine compartment installation spaces and layout requirements, thus improving the versatility and applicability of the balance valve seat.

[0009] 2. This utility model features two symmetrical movable plates whose bottoms are slidably connected to the top of an arc-shaped hanging ring. An arc-shaped clamp fixedly connected to the inner side of each movable plate can fit against the valve stem surface. When the valve stem needs to be fixed, rotating the bidirectional screw with a locking device causes the two movable plates to move synchronously towards or away from each other, as the nut seat is threadedly connected to the bidirectional screw. This allows the arc-shaped clamp to tightly hold the valve stem, making operation convenient and ensuring reliable fixation of the valve stem. This prevents the valve stem from shaking or displacement due to vibrations during vehicle operation, ensuring stable operation of the balance valve and improving the stability and reliability of the automotive air conditioning system. Furthermore, the locking device prevents accidental rotation of the bidirectional screw, further enhancing the clamping and locking effect. Attached Figure Description

Detailed Implementation

[0011] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0012] like Figures 1 to 6 As shown, the automotive air conditioning balance valve seat of this embodiment includes a balance valve body 1, a valve stem 2 is provided on the top of the balance valve body 1, a connecting seat 3 is attached to the bottom of the balance valve body 1, and arc-shaped hanging rings 4 are hinged to both sides of the rear of the connecting seat 3 through hinge seats. The inner surface of the arc-shaped hanging rings 4 is attached to the top of the balance valve body 1, and the front end of the arc-shaped hanging rings 4 is fixedly connected to the top of the connecting seat 3 by bolts. Synchronous connecting plates 5 are fixedly connected to the front and rear sides of the opposite side of the two arc-shaped hanging rings 4. A clamping and locking structure 6 is provided on the top of the arc-shaped hanging rings 4. The output end of the clamping and locking structure 6 is attached to the surface of the valve stem 2 for fixing the valve stem 2. A mounting plate 7 is provided at the bottom of the connecting seat 3. Mounting feet are provided at the four corners of the mounting plate 7. Bolts can be used to fix the mounting plate 7 to the corresponding threaded holes in the engine compartment. A spacing adjustment mechanism 8 is provided between the connecting seat 3 and the mounting plate 7 for adjusting the mounting spacing.

[0013] refer to Figure 1 The clamping and locking structure 6 includes two symmetrically arranged movable plates 9. The bottom of the movable plate 9 is slidably connected to the top of the arc-shaped hanging ring 4. An arc-shaped clamp 10 is fixedly connected to the inner side of the movable plate 9. The inner side of the arc-shaped clamp 10 is in contact with the surface of the valve stem 2. A nut seat 11 is fixedly connected to the top of the movable plate 9. A bidirectional screw 12 with a locking device is connected to the internal thread of the nut seat 11.

[0014] This embodiment uses two symmetrical movable plates 9, whose bottoms are slidably connected to the top of the arc-shaped hanging ring 4. The arc-shaped clamp 10, which is fixedly connected to the inner side of the movable plates 9, can fit against the surface of the valve stem 2. When it is necessary to fix the valve stem 2, the bidirectional screw 12 with a locking device is rotated. Since the nut seat 11 is threadedly connected to the bidirectional screw 12, the rotation of the bidirectional screw 12 will drive the two movable plates 9 to move synchronously towards or away from each other, so that the arc-shaped clamp 10 can tightly clamp the valve stem 2. The operation is convenient and can reliably fix the valve stem 2, preventing the valve stem 2 from shaking or displacement due to vibration and other factors during vehicle operation. This ensures the stable operation of the balance valve and improves the working stability and reliability of the automotive air conditioning system. At the same time, the locking device can prevent the bidirectional screw 12 from rotating accidentally, further enhancing the clamping and locking effect.

[0015] refer to Figure 1The spacing adjustment mechanism 8 includes an internally threaded sleeve 13 rotatably connected to the bottom of the connecting seat 3 and a threaded post 14 fixedly connected to the top of the mounting plate 7. The surface of the threaded post 14 is threadedly connected to the inner surface of the internally threaded sleeve 13. The surface of the internally threaded sleeve 13 is provided with a locking threaded hole that communicates with both the inside and outside. A locking bolt 15 is threadedly connected to the inside of the locking threaded hole. A spring block is rotatably connected to the rear end of the locking bolt 15. The rear side of the spring block is in contact with the surface of the threaded post 14.

[0016] In this embodiment, an internally threaded sleeve 13, rotatably connected to the bottom of the connecting seat 3, is threadedly connected to a threaded post 14, fixedly connected to the top of the mounting plate 7. By rotating the internally threaded sleeve 13, the threaded post 14 can be screwed in or out of the internally threaded sleeve 13, thereby adjusting the distance between the connecting seat 3 and the mounting plate 7. This allows the balance valve seat to be flexibly adjusted according to the actual space and installation requirements of different car engine compartments, improving its versatility and adaptability. The locking threaded hole on the surface of the internally threaded sleeve 13 and the locking bolt 15 connected to the internal thread can be tightened after the distance is adjusted, so that the elastic block rotatably connected at the rear end fits against the surface of the threaded post 14. The elasticity and friction of the elastic block fix the internally threaded sleeve 13 and the threaded post 14 relatively, preventing the distance from changing due to vibration or other reasons during car operation, thus ensuring the stability and reliability of the balance valve seat installation.

[0017] refer to Figure 1 The four corners of the connecting seat 3 are provided with circular grooves, and the inside of the circular grooves is slidably connected to the guide post 16 through a sliding sleeve. The bottom end of the guide post 16 is fixedly connected to the top of the mounting plate 7.

[0018] In this embodiment, by setting the circular grooves at the four corners of the connecting seat 3 and the guide posts 16 that are slidably connected inside, the guide posts 16 can provide guidance for the movement of the connecting seat 3 when the spacing adjustment mechanism 8 adjusts the spacing between the connecting seat 3 and the mounting plate 7. This ensures that the connecting seat 3 moves smoothly along the direction of the guide posts 16, avoiding any deviation or shaking of the connecting seat 3 during movement, making the spacing adjustment more precise and stable. At the same time, the cooperation between the guide posts 16 and the sliding sleeve can also enhance the connection strength and stability between the connecting seat 3 and the mounting plate 7, further improving the overall structural stability of the balance valve seat, which is conducive to the balance valve playing a better role in the automotive air conditioning system.

[0019] refer to Figure 5 An elastic pad 17 is fixedly connected to the top of the inner wall of the arc-shaped hanging ring 4 and the top of the connecting seat 3. The surface of the elastic pad 17 is provided with friction texture, and the surface of the elastic pad 17 is in contact with the surface of the balance valve body 1.

[0020] This embodiment has a good beneficial effect by setting the elastic pad 17. The surface of the elastic pad 17 is provided with friction texture, and its surface is in contact with the surface of the balance valve body 1. The elasticity of the elastic pad 17 can play a buffering role, reducing the impact of vibration on the balance valve body 1 during vehicle operation, protecting the balance valve body 1 from damage, and extending its service life. The setting of friction texture increases the friction between the elastic pad 17 and the surface of the balance valve body 1, so that the balance valve body 1 can be more firmly fixed between the connecting seat 3 and the arc-shaped hanging ring 4, preventing the balance valve body 1 from sliding or loosening during vibration, improving the fixing effect of the balance valve seat on the balance valve, and ensuring the stable operation of the balance valve.

[0021] refer to Figure 5 A rubber plate 18 is fixedly connected to the bottom of the mounting plate 7, and the bottom of the rubber plate 18 is provided with anti-slip texture.

[0022] This embodiment, by setting the rubber plate 18 to have a certain degree of elasticity and cushioning performance, can reduce the rigid contact between the balance valve seat and the vehicle engine compartment mounting surface, reduce vibration transmission, play a role in shock absorption and noise reduction, and improve the usage environment inside the vehicle. The anti-slip texture increases the friction between the rubber plate 18 and the vehicle engine compartment mounting surface, preventing the balance valve seat from sliding or displacing due to vibration or other reasons during vehicle operation, ensuring the installation stability of the balance valve seat in the vehicle engine compartment, thereby ensuring the stable operation of the entire vehicle air conditioning balance valve system.

[0023] This invention achieves initial positioning by fixing the mounting plate 7 to the corresponding threaded holes in the car's engine compartment using bolts via its four corner mounting feet. Next, based on the actual space and layout requirements of the car's engine compartment, the spacing adjustment mechanism 8 is used to adjust the spacing between the connecting seat 3 and the mounting plate 7. Rotating the internal threaded sleeve 13 at the bottom of the connecting seat 3 causes the threaded post 14 at the top of the mounting plate 7 to rotate, thus changing the spacing. After adjustment, the locking bolt 15 in the locking threaded hole on the surface of the internal threaded sleeve 13 is tightened, causing the elastic block at the rear end to fit tightly against the surface of the threaded post 14. The elasticity and friction of the elastic block then engage the internal threaded sleeve. The cylinder 13 and the threaded column 14 are fixed relative to each other to prevent changes in the spacing. Then, the bottom of the balance valve body 1 is attached to the connecting seat 3. The arc-shaped hanging rings 4, which are hinged to the two sides of the rear of the connecting seat 3 through the hinge seat, are rotated forward so that their inner surfaces are attached to the top of the balance valve body 1. The front end of the arc-shaped hanging ring 4 is then fixed to the top of the connecting seat 3 with bolts. Finally, the clamping and locking structure 6 at the top of the arc-shaped hanging ring 4 is operated to rotate the double-acting screw 12 with the locking device. Since the nut seat 11 is threadedly connected to the double-acting screw 12, the rotation of the double-acting screw 12 will drive the two moving plates 9, whose bottoms are slidably connected to the top of the arc-shaped hanging ring 4, to move synchronously towards each other. This causes the arc-shaped clamp 10, which is fixedly connected to the inner side of the moving plate 9, to tightly clamp the valve stem 2 at the top of the balance valve body 1, preventing the valve stem 2 from shaking.
