[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] Embodiment 1
[0024] See also Figure 1-4 A solenoid valve for new energy vehicles with a noise reduction function comprises a valve body 1 and a controller 2. A lower docking piece 4 is integrally formed on the top of the valve body 1, and an upper docking piece 3 is integrally formed on the bottom of the controller 2. Threaded holes of the same size are provided on the inner walls of the upper docking piece 3 and the lower docking piece 4. A fixing bolt 5 is connected to the internal thread of the threaded hole. A stabilizing component 6 is arranged between the fixing bolt 5 and the top surface of the upper docking piece 3. The stabilizing component 6 comprises an upper snap ring 61 and a lower snap ring 62 which fit each other. An upper reverse tooth 63 is arranged on the top surface of the upper snap ring 61. An upper wedge-shaped groove 65 is arranged on the portion of the upper snap ring 61 close to the lower snap ring 62. A lower reverse tooth 67 is arranged on the bottom surface of the lower snap ring 62. A lower wedge-shaped groove 66 is arranged on the side of the lower snap ring 62 close to the upper snap ring 61, and the lower wedge-shaped groove 66 is matched with the upper wedge-shaped groove 65.
[0025] For further information, see Figure 4 A through slot 64 is provided in the middle part of the upper snap ring 61 and the lower snap ring 62, and the through slot 64 is matched with the fixing bolt 5. By setting the through slot 64 and setting the through slot 64 to be matched with the fixing bolt 5, the fixing bolt 5 can easily complete the installation and fixation of the stabilizing component 6 through the through slot 64.
[0026] For further information, see Figure 1-2 The top areas of the upper docking piece 3 and the lower docking piece 4 are the same, and four threaded holes are evenly opened on the outer walls of the upper docking piece 3 and the lower docking piece 4, and fixing bolts 5 are installed in the four threaded holes. The specific number of the stabilizing components 6 is four, and the four stabilizing components 6 are respectively installed under the four fixing bolts 5. By setting the specific number of the stabilizing components 6 to four, and setting four stabilizing components 6, which are respectively installed under the four fixing bolts 5, the connection between the lower docking piece 4 and the upper docking piece 3 is more stable, and each fixing bolt 5 used for fixing will not loosen easily.
[0027] In addition, a groove is provided on the top surface of the upper docking piece 3, and a valve cover 7 matching the groove is installed inside the groove.
[0028] In addition, a guide tube 8 is integrally formed on one side of the valve body 1, and the meshing angle between the lower wedge groove 66 and the upper wedge groove 65 is greater than the angle of the internal thread of the fixing bolt 5. By providing the guide tube 8, it can be ensured that the medium can flow along a predetermined path inside the device.
[0029] During specific implementation, most of the noise generated in the battery valve is caused by the loose connection between the various parts. During the operation of the device, the loose parts will inevitably collide, so a lot of noise will be generated after the collision. In this application, a fixing bolt 5 is threadedly connected between the lower docking piece 4 and the fixing bolt 5 for fixing the valve body 1 and the controller 2, and a stabilizing component 6 is installed between the fixing bolt 5 and the top surface of the upper docking piece 3, so that the fixing bolt 5 will not loosen easily after being tightened.
[0030] Before installing the fixing bolt 5, the stabilizing component 6 is sleeved on the outer wall of the fixing bolt 5, and then the fixing bolt 5 is screwed counterclockwise into the upper docking piece 3 and the lower docking piece 4. During the screwing process, since the upper reverse tooth 63 is close to the bottom surface of the fixing bolt 5, and the lower reverse tooth 67 is close to the top surface of the upper docking piece 3, and the teeth in the through groove 64 and the lower reverse tooth 67 are oppositely arranged, the fixing bolt 5 will not be affected by the through groove 64 opened at the upper end of the upper retaining ring 61 when it rotates counterclockwise. Similarly, the lower retaining ring 62 can rotate smoothly on the top surface of the upper docking piece 3 because the teeth of the lower reverse tooth 67 are oppositely arranged to the upper reverse tooth 63 until the fixing bolt 5 is tightened. After the fixing bolt 5 is tightened, the upper reverse tooth 63 will be embedded in the fixing bolt 5, and the lower reverse tooth 67 will be embedded in the top surface of the upper docking piece 3.
[0031] At this time, the entire device vibrates again. When the fixing bolt 5 wants to rotate in the opposite direction due to the vibration, the upper wedge groove 65 and the lower wedge groove 66 that are engaged with each other will generate a reaction force, which prevents the fixing bolt 5 from easily reversing. Among them, since the angle of the upper wedge groove 65 and the lower wedge groove 66 is greater than the angle of the thread in the fixing bolt 5, this design enables the upper retaining ring 61 and the lower retaining ring 62 to more effectively resist the loosening tendency when subjected to external forces such as vibration or impact. When the fixing bolt 5 tries to loosen, the lower wedge groove 66 and the upper wedge groove 65 in the upper retaining ring 61 and the lower retaining ring 62 will generate a reverse clamping force, which increases with the increase of the loosening tendency, thereby maintaining the stability of the connection.
[0032] In general, when the fixing bolt 5 is tightened, the upper retaining ring 61 and the lower retaining ring 62 form a wedge effect under the upper wedge-shaped groove 65, increasing the tightening force of the fixing bolt 5. Under the action of vibration or external force, the lower wedge-shaped groove 66 and the upper wedge-shaped groove 65 of the upper retaining ring 61 and the lower retaining ring 62 can resist the loosening tendency and maintain the tightening state of the bolt through self-locking force, thereby effectively preventing the bolt from loosening.
[0033] By providing the stabilizing component 6, the lower docking piece 4 and the upper docking piece 3 in the device cannot be easily loosened after being fixed to the stabilizing component 6 by the fixing bolts 5, and the device as a whole will not easily generate noise during subsequent use.
[0034] Embodiment 2
[0035] Based on Example 1, please refer to Figure 1-4 , a solenoid valve for new energy vehicles with a noise reduction function, wherein, when the user needs to disassemble the upper docking piece 3 and the lower docking piece 4 to inspect the inside of the device, the user can directly rotate the fixing bolt 5 clockwise. Although the angle of the upper wedge groove 65 and the lower wedge groove 66 is greater than the angle of the thread in the fixing bolt 5, the clamping force of the stabilizing component 6 can be overcome by applying sufficient reverse torque. At this time, since the design of the lower wedge groove 66 and the upper wedge groove 65 allows relative sliding within a certain angle range, the clamping force on the gasket can be gradually released by rotating the fixing bolt 5 in the opposite direction, and finally the fixing bolt 5 can be easily screwed out.
[0036] By providing the stabilizing assembly 6, the stability of the bolt under normal working conditions is ensured, and the disassembly operation when necessary is facilitated, thereby increasing the practicability of the device.
[0037] Working principle: Most of the noise generated in the battery valve is caused by the loose connection between the various parts. During the operation of the device, the loose parts will inevitably collide, so a lot of noise will be generated after the collision. In this application, a fixing bolt 5 is threadedly connected between the lower docking piece 4 and the fixing bolt 5 for fixing the valve body 1 and the controller 2, and a fixing component 6 is installed between the fixing bolt 5 and the top surface of the upper docking piece 3, so that the fixing bolt 5 will not loosen easily after being tightened.
[0038] Before installing the fixing bolt 5, the stabilizing component 6 is sleeved on the outer wall of the fixing bolt 5, and then the fixing bolt 5 is screwed counterclockwise into the upper docking piece 3 and the lower docking piece 4. During the screwing process, since the upper reverse tooth 63 is close to the bottom surface of the fixing bolt 5, and the lower reverse tooth 67 is close to the top surface of the upper docking piece 3, and the teeth in the through groove 64 and the lower reverse tooth 67 are oppositely arranged, the fixing bolt 5 will not be affected by the through groove 64 opened at the upper end of the upper retaining ring 61 when it rotates counterclockwise. Similarly, the lower retaining ring 62 can rotate smoothly on the top surface of the upper docking piece 3 because the teeth of the lower reverse tooth 67 are oppositely arranged to the upper reverse tooth 63 until the fixing bolt 5 is tightened. After the fixing bolt 5 is tightened, the upper reverse tooth 63 will be embedded in the fixing bolt 5, and the lower reverse tooth 67 will be embedded in the top surface of the upper docking piece 3.
[0039] At this time, the entire device vibrates again. When the fixing bolt 5 wants to rotate in the opposite direction due to the vibration, the upper wedge groove 65 and the lower wedge groove 66 that are engaged with each other will generate a reaction force, which prevents the fixing bolt 5 from easily reversing. Among them, since the angle of the upper wedge groove 65 and the lower wedge groove 66 is greater than the angle of the thread in the fixing bolt 5, this design enables the upper retaining ring 61 and the lower retaining ring 62 to more effectively resist the loosening tendency when subjected to external forces such as vibration or impact. When the fixing bolt 5 tries to loosen, the lower wedge groove 66 and the upper wedge groove 65 in the upper retaining ring 61 and the lower retaining ring 62 will generate a reverse clamping force, which increases with the increase of the loosening tendency, thereby maintaining the stability of the connection.
[0040] In general, when the fixing bolt 5 is tightened, the upper retaining ring 61 and the lower retaining ring 62 form a wedge effect under the upper wedge-shaped groove 65, increasing the tightening force of the fixing bolt 5. Under the action of vibration or external force, the lower wedge-shaped groove 66 and the upper wedge-shaped groove 65 of the upper retaining ring 61 and the lower retaining ring 62 can resist the loosening tendency and maintain the tightening state of the bolt through self-locking force, thereby effectively preventing the bolt from loosening.
[0041] When the user needs to remove the upper docking piece 3 and the lower docking piece 4 to inspect the inside of the device, the user can directly rotate the fixing bolt 5 clockwise. Although the angle of the upper wedge groove 65 and the lower wedge groove 66 is greater than the angle of the thread in the fixing bolt 5, the clamping force of the stabilizing component 6 can be overcome by applying sufficient reverse torque. At this time, since the design of the lower wedge groove 66 and the upper wedge groove 65 allows relative sliding within a certain angle range, the clamping force on the gasket can be gradually released by rotating the fixing bolt 5 in the opposite direction, and finally the fixing bolt 5 can be easily screwed out.
[0042] By providing the stabilizing component 6, the lower docking piece 4 and the upper docking piece 3 in the device cannot be easily loosened after being fixed to the stabilizing component 6 by the fixing bolts 5, and the device as a whole will not easily generate noise during subsequent use.
[0043] By providing the stabilizing assembly 6, the stability of the bolt under normal working conditions is ensured, and the disassembly operation when necessary is facilitated, thereby increasing the practicability of the device.
