Description

Technical Field

[0001] The present invention relates to the technical field of automotive flow channel plates, and particularly to an automotive flow channel plate. Background Art

[0002] The flow channel plate, which is a core component of an automotive hydraulic mount, is an important component to ensure the normal operation of the hydraulic mount. The requirements for its product precision, quality, and various performance indicators play a crucial role in the working effect of the hydraulic mount. It mainly functions to provide sealing and generate damping.

[0003] Existing hydraulic mount flow channel plates achieve sealing through the extrusion of the overall structure of the hydraulic mount. This installation method has an unstable structure, resulting in the flow channel plate being prone to loosening and leakage. At the same time, it is not convenient for subsequent replacement and repair of the decoupling diaphragm. In view of the above problems, an innovative design is carried out on the basis of the original automotive flow channel plate. Summary of the Invention

[0004] The purpose of the present invention is to provide an automotive flow channel plate to solve the problems in the above-mentioned background art, where existing hydraulic mount flow channel plates achieve sealing through the extrusion of the overall structure of the hydraulic mount. This installation method has an unstable structure, resulting in the flow channel plate being prone to loosening and leakage. At the same time, it is not convenient for subsequent replacement and repair of the decoupling diaphragm.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An automotive flow channel plate includes an upper flow channel plate. A lower flow channel plate is provided below the upper flow channel plate. First perforations and second perforations are respectively formed on the upper flow channel plate and the lower flow channel plate. A docking groove and a docking ring are respectively provided on the lower surface of the upper flow channel plate and the upper surface of the lower flow channel plate. A cross bar is connected to the docking ring and is installed on the upper flow channel plate. A return spring is provided outside the cross bar and is located inside the upper flow channel plate. A decoupling diaphragm is provided between the upper flow channel plate and the lower flow channel plate. Insertion rods are provided at the edge of the decoupling diaphragm. The insertion rods are installed on the lower surface of the upper flow channel plate, and the lower ends of the insertion rods are located inside the slots, and the slots are formed on the upper surface of the lower flow channel plate. A third perforation is formed at the middle position of the decoupling diaphragm, and a sealing ring is provided outside the third perforation and is located between the upper flow channel plate and the decoupling diaphragm.

[0006] Preferably, the docking groove and the docking ring fit each other, and the docking ring and the lower flow channel plate are integrally designed.

[0007] Preferably, the cross bar is connected through the docking ring in a penetrating manner, and the cross bar and the upper flow channel plate form a telescopic structure through the return spring.

[0008] Preferably, the edge position of the decoupling diaphragm is a "V" - shaped structure, and the decoupling diaphragm is made of stainless steel.

[0009] Preferably, the insertion rod and the insertion slot correspond to each other, and the insertion slots are angularly distributed on the upper surface of the downstream flow channel plate.

[0010] Preferably, the sealing ring is heat-melted and connected to the upper surface of the decoupling diaphragm, and the sealing ring is adhesively connected to the lower surface of the upstream flow channel plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: for this automotive flow channel plate,

[0012] 1. It can stably clamp and install the decoupling diaphragm between the upstream flow channel plate and the downstream flow channel plate. At the same time, the upstream flow channel plate and the downstream flow channel plate are stably docked and locked through the docking ring and the docking groove, which can prevent loosening between the upstream flow channel plate and the downstream flow channel plate, and can also avoid loosening and leakage of the installation of the decoupling diaphragm.

[0013] 2. When the liquid passes through the upstream flow channel plate, the liquid will squeeze the decoupling diaphragm, facilitating the disconnection of the sealing ring on the decoupling diaphragm from the lower surface of the upstream flow channel plate, thereby opening the flow channel plate to facilitate the liquid to flow through the first through-hole, the second through-hole, and the third through-hole. When the liquid does not exert pressure on the decoupling diaphragm, the decoupling diaphragm will rebound and close under the action of its own "V"-shaped structure.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: an automotive flow channel plate, which includes an upper flow channel plate 1. A lower flow channel plate 2 is arranged below the upper flow channel plate 1. First through holes 3 and second through holes 4 are respectively formed on the upper flow channel plate 1 and the lower flow channel plate 2. A docking groove 5 and a docking ring 6 are respectively arranged on the lower surface of the upper flow channel plate 1 and the upper surface of the lower flow channel plate 2. A cross bar 7 is connected to the docking ring 6, and the cross bar 7 is installed on the upper flow channel plate 1. A return spring 8 is arranged outside the cross bar 7, and the return spring 8 is located inside the upper flow channel plate 1. A decoupling diaphragm 9 is arranged between the upper flow channel plate 1 and the lower flow channel plate 2. A plug rod 10 is arranged at the edge of the decoupling diaphragm 9. The plug rod 10 is installed on the lower surface of the upper flow channel plate 1, and the lower end of the plug rod 10 is located inside a slot 11, and the slot 11 is formed on the upper surface of the lower flow channel plate 2. A third through hole 12 is formed at the middle position of the decoupling diaphragm 9, and a sealing ring 13 is arranged outside the third through hole 12, and the sealing ring 13 is located between the upper flow channel plate 1 and the decoupling diaphragm 9.

[0021] The docking groove 5 and the docking ring 6 fit with each other, and the docking ring 6 and the lower flow channel plate 2 are integrally designed, which facilitates the stable docking and splicing of the lower flow channel plate 2 and the upper flow channel plate 1 through the cooperation between the docking groove 5 and the docking ring 6.

[0022] The cross bar 7 is connected through the docking ring 6 in a penetrating manner, and the cross bar 7 and the upper flow channel plate 1 form a telescopic structure through the return spring 8, which is beneficial for the return spring 8 to push the cross bar 7 to move. At this time, the cross bar 7 can pass through the docking ring 6 to lock the position of the docking ring 6.

[0023] The edge position of the decoupling diaphragm 9 is of a "V" - shaped structure, and the decoupling diaphragm 9 is made of stainless steel, which is convenient for the decoupling diaphragm 9 to perform a reset movement after being deformed under pressure and can achieve automatic opening and closing.

[0024] The plug rod 10 and the slot 11 correspond to each other, and the slots 11 are evenly distributed on the upper surface of the lower flow channel plate 2, which can lock the edge position of the decoupling diaphragm 9, improve the stability of the installation of the decoupling diaphragm 9, and prevent the decoupling diaphragm 9 from loosening.

[0025] The sealing ring 13 is heat - melted and connected to the upper surface of the decoupling diaphragm 9, and the sealing ring 13 is fitted and connected to the lower surface of the upper flow channel plate 1. When the decoupling diaphragm 9 pushes the sealing ring 13 to fit with the lower surface of the upper flow channel plate 1, it is closed at this time. When the liquid exerts pressure on the decoupling diaphragm 9 and causes deformation, the decoupling diaphragm 9 drives the sealing ring 13 to disconnect from the lower surface of the upper flow channel plate 1, and then the opening is completed.

[0026] Working principle: According to Figures 1-4As shown in the figure, first place the decoupling diaphragm 9 between the upper flow channel plate 1 and the lower flow channel plate 2, manually pull the cross bar 7 to move outward on the upper flow channel plate 1, and then buckle the upper flow channel plate 1 on the lower flow channel plate 2 until the insertion rod 10 on the lower surface of the upper flow channel plate 1 is inserted into the slot 11 and the docking ring 6 on the upper surface of the lower flow channel plate 2 is inserted into the docking groove 5 on the lower surface of the upper flow channel plate 1. At this time, manually release the pulled cross bar 7, and then the return spring 8 will push the cross bar 7 to move. At this time, the cross bar 7 passes through the docking ring 6 under the pushing action of the return spring 8, thus completing the locking of the position of the docking ring 6 and improving the connection stability between the upper flow channel plate 1 and the lower flow channel plate 2. At this time, the insertion rod 10 also passes through the decoupling diaphragm 9 and is inserted into the slot 11, improving the installation stability of the decoupling diaphragm 9. When the liquid applies pressure to the decoupling diaphragm 9 through the first through hole 3 on the upper flow channel plate 1, the decoupling diaphragm 9 deforms at this time, and the sealing ring 13 on the upper surface of the decoupling diaphragm 9 is disconnected from the lower surface of the upper flow channel plate 1. At this time, the liquid can flow through the first through hole 3, the second through hole 4 and the third through hole 12. When the liquid no longer applies pressure to the decoupling diaphragm 9, the decoupling diaphragm 9 rebounds through its own "V"-shaped structure. At this time, the decoupling diaphragm 9 pushes the sealing ring 13 to fit and connect with the lower surface of the upper flow channel plate 1 again. Therefore, the liquid cannot flow through the third through hole 12 at this time. Such an automobile flow channel plate is convenient for people to use.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
