Description

Technical Field

[0001] This utility model relates to the field of automotive generator technology, specifically disclosing a carbon canister with a spring-supported locking structure. Background Technology

[0002] Carbon canisters, also known as activated carbon canisters or fuel evaporation control canisters, can be divided into integrated carbon canisters and split carbon canisters according to their design. They are the core components of automotive fuel evaporation emission control systems. The interior of the carbon canister is filled with activated carbon to adsorb and temporarily store gasoline vapors volatilized from the fuel tank, preventing the vapors from being directly emitted into the atmosphere and causing pollution. Carbon canisters are widely used in internal combustion engine vehicles, especially models equipped with fuel evaporation emission control systems.

[0003] In the existing technology, when welding the upper and lower tanks of the carbon canister, the activated carbon particles inside the tank cannot be compacted. This can easily lead to friction between the activated carbon particles during the welding process, resulting in activated carbon powder. The activated carbon powder may block the precision air passage in the leak detection pump on the carbon canister, causing the leak detection pump to malfunction or even fail, seriously affecting the service life of the carbon canister. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a carbon canister with a spring-supported locking structure, which can compact the activated carbon particles, reduce the friction of activated carbon particles and the generation of activated carbon powder during the welding process of the canister, thereby reducing the failure rate of the leakage detection pump on the carbon canister and improving the service life of the carbon canister.

[0005] The technical solution adopted by this utility model to solve its technical problem is: The aforementioned spring-supported carbon canister with a locking structure includes an upper canister and a lower canister fixedly connected. Both the upper and lower canisters are filled with activated carbon particles. A spring support plate 1 is provided at the bottom of the inner cavity of the upper canister, and a spring support plate 2 is provided at the top of the inner cavity of the lower canister in conjunction with the spring support plate 1. Several springs are fixedly and intermittently arranged through the spring support plate 1 and the spring support plate 2. Locking assemblies are provided between the two sides of the spring support plate 1 and the upper canister, and between the two sides of the spring support plate 2 and the lower canister. The locking assemblies include several locking blocks and several sets of locking grooves. Several locking blocks are fixedly arranged on the two sides of the spring support plate 1 and the spring support plate 2, and several sets of locking grooves are formed on the inner walls of the two sides of the upper and lower canisters in conjunction with several locking blocks. The locking blocks can be engaged in the locking grooves.

[0006] Furthermore, two sets of springs are provided, with the two sets of springs spaced apart in the middle of spring support plate one and spring support plate two.

[0007] Furthermore, non-woven fabric is fixedly installed on the opposite sides of both spring support plate one and spring support plate two, and the two ends of the spring pass through the two sets of non-woven fabric and extend into the upper tank and the lower tank respectively.

[0008] Furthermore, on the side of spring support plate one near spring support plate two, two sets of support blocks one are fixedly installed in conjunction with two sets of springs, and on the side of spring support plate two near spring support plate one, two sets of support blocks two are fixedly installed in conjunction with two sets of springs.

[0009] Furthermore, the cross-sections of both support block one and support block two are cross-shaped, and the springs are fixedly sleeved on the outer surfaces of support block one and support block two.

[0010] Furthermore, there are eight locking blocks and eight sets of locking slots. Two locking blocks are respectively provided on both sides of the first spring support plate and the second spring support plate. Two sets of locking slots are respectively provided on the inner walls of both sides of the upper tank and the inner walls of both sides of the lower tank. Each set of locking slots includes several locking slots that are evenly opened longitudinally.

[0011] Furthermore, a limit block is fixedly installed on the lower end face of the upper tank, and a limit groove is opened on the upper end face of the lower tank in coordination with the limit block, with the limit block engaging in the limit groove.

[0012] Furthermore, both the limiting block and the limiting groove have a rectangular ring structure.

[0013] Furthermore, an outlet end is fixedly provided at the top of the upper tank, and an inlet end is fixedly provided at the bottom of the lower tank.

[0014] Furthermore, the outlet end is connected to a carbon canister solenoid valve, and the inlet end is connected to a fuel tank.

[0015] The beneficial effects of this utility model are: This invention, by setting up a first spring support plate, a second spring support plate, a spring, and a locking assembly, allows the first and second spring support plates to be pushed towards each other under the elastic force of the springs, thus compacting the activated carbon particles in the upper and lower tanks. This reduces friction between the activated carbon particles and the generation of activated carbon powder during the welding process of the upper and lower tanks, thereby reducing the failure rate of the carbon canister, increasing its service life, and significantly reducing vehicle maintenance costs. The locking block, engaged in the locking groove, prevents the first and second spring support plates from being squeezed by the activated carbon particles and moving in the opposite direction, ensuring thorough compaction of the activated carbon particles and further guaranteeing the stability of the device's operation.

[0018] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0019] Example 1 like Figure 1-3 As shown, the carbon canister with spring support and locking structure includes an upper canister 1 and a lower canister 2 fixedly connected. Both the upper canister 1 and the lower canister 2 are filled with activated carbon particles. A spring support plate 1 is provided at the bottom of the inner cavity of the upper canister 1, and a spring support plate 2 is provided at the top of the inner cavity of the lower canister 2 in conjunction with the spring support plate 1. Several springs 5 ​​are fixedly and intermittently arranged through the spring support plate 1 and the spring support plate 2. Locking assemblies are provided between the two sides of the spring support plate 1 and the upper canister 1, and between the two sides of the spring support plate 2 and the lower canister 2. The locking assemblies include several locking blocks 6 and several sets of locking grooves 7. Several locking blocks 6 are fixedly arranged on the two sides of the spring support plate 1 and the spring support plate 2. Several sets of locking grooves 7 are formed on the inner walls of the two sides of the upper canister 1 and the lower canister 2 in conjunction with several locking blocks 6. The locking blocks 6 can be engaged in the locking grooves 7.

[0020] This invention, by setting up a spring support plate 3, a spring support plate 4, a spring 5, and a locking assembly, allows the spring support plates 3 and 4 to be pushed in opposite directions under the elastic force of the spring 5. This compacts the activated carbon particles in the upper tank 1 and lower tank 2, reducing friction between the activated carbon particles and the generation of activated carbon powder during the welding process of the upper tank 1 and lower tank 2. This reduces the failure rate of the carbon canister, increases its service life, and significantly reduces vehicle maintenance costs. The locking block 6, engaged in the locking groove 7, prevents the spring support plates 3 and 4 from being squeezed by the activated carbon particles and moving in the opposite direction, ensuring thorough compaction of the activated carbon particles and further guaranteeing the stability of the device.

[0021] Two sets of springs 5 ​​are provided, with the two sets of springs 5 ​​spaced apart in the middle of spring support plate 1 3 and spring support plate 2 4. The two sets of springs 5 ​​are symmetrically arranged to ensure the stability of the compaction process of activated carbon particles by spring support plate 1 3 and spring support plate 2 4.

[0022] Non-woven fabric 8 is fixedly installed on the opposite sides of spring support plate 3 and spring support plate 4, and the two ends of the spring 5 pass through the two sets of non-woven fabric 8 and extend into the upper tank 1 and lower tank 2 respectively. The breathable structure of the non-woven fabric 8 allows fuel vapor to pass evenly through the activated carbon layer, avoiding airflow short circuits. Furthermore, when the vehicle vibrates, the non-woven fabric 8 can buffer the friction between activated carbon particles and prevent them from pulverizing.

[0023] Two sets of support blocks 19 are fixedly installed on the side of spring support plate 13 near spring support plate 24 in conjunction with two sets of springs 5. Two sets of support blocks 20 are fixedly installed on the side of spring support plate 24 near spring support plate 13 in conjunction with two sets of springs 5.

[0024] Both support block 1 (9) and support block 2 (10) have a cross-shaped cross-section, and spring 5 is fixedly sleeved on the outer surface of support block 1 (9) and support block 2 (10). By setting support block 1 (9) and support block 2 (10), spring 5 can be further fixed, further ensuring the stability of spring support plate 1 (3) and spring support plate 2 (4) in the compaction process of activated carbon particles.

[0025] Eight locking blocks 6 are provided, and eight sets of locking slots 7 are provided in coordination. Two locking blocks 6 are provided on each side of the first spring support plate 3 and each side of the second spring support plate 4. Two sets of locking slots 7 are provided on each side of the inner wall of the upper tank 1 and the inner wall of the lower tank 2. Each set of locking slots 7 includes several locking slots 7 evenly spaced longitudinally. The longitudinal section of the locking slot 7 is generally a right-angled triangle structure. When the first spring support plate 3 and the second spring support plate 4 move to opposite sides, the locking blocks 6 sequentially engage several locking slots 7 until the first spring support plate 3 and the second spring support plate 4 can no longer move. At this time, the locking blocks 6 are engaged in the appropriate locking slots 7. Due to the structure of the locking blocks 6 and the locking slots 7, the first spring support plate 3 and the second spring support plate 4 are prevented from being squeezed by the activated carbon particles and thus moving in the opposite direction, further ensuring the stability of the compaction process of the activated carbon particles by the first spring support plate 3 and the second spring support plate 2.

[0026] A limiting block 11 is fixedly installed on the lower end face of the upper tank 1, and a limiting groove is formed on the upper end face of the lower tank 2 to cooperate with the limiting block 11. The limiting block 11 is snapped into the limiting groove. The upper tank 1 and the lower tank 2 are fixedly connected by welding. The limiting block 11 acts as a sealing ring to ensure the sealing of the connection between the upper tank 1 and the lower tank 2.

[0027] Both the limiting block 11 and the limiting groove are rectangular ring structures. The structure of the limiting block 11 and the limiting groove is adapted to the structure of the contact surface of the upper tank 1 and the lower tank 2, which can further ensure the sealing of the connection between the upper tank 1 and the lower tank 2.

[0028] An outlet end 12 is fixedly installed at the top of the upper tank 1, and an inlet end 13 is fixedly installed at the bottom of the lower tank 2.

[0029] The outlet end 12 is connected to an external carbon canister solenoid valve, and the inlet end 13 is connected to an external fuel tank. The outlet end 12 is connected to the intake manifold or the rear of the throttle valve of the engine through the carbon canister solenoid valve, and the inlet end 13 is directly connected to the top of the fuel tank through a vapor pipe to collect the vapor generated by fuel evaporation.
