Description

Technical Field

[0001] The utility model relates to the technical field of shock absorption and fixing structures, in particular to a shock absorption and fixing structure for a water pump and a manifold of a thermal management module. Background Art

[0002] The thermal management system of electric vehicles involves occupant compartment refrigeration and heating, motor cooling, battery cooling and heating, etc., which has become increasingly complex; especially after the application of the heat pump system, a large number of new parts are added; in order to save the front cabin space, reduce pipeline connections and lower costs, the thermal management integrated module with an integrated solution of a water pump, a water valve, an EXV, an SOV, a heat exchanger, etc. has been widely used; after the water pump is integrated into the integrated module, many NVH problems such as shock absorption design, structural mode, and fluid noise are brought about. The water pump is the vibration source of the integrated module, so its installation and fixing method is particularly important.

[0003] At present, there are mainly two ways to fix the water pump and the manifold:

[0004] 1. Fix it on the manifold by self-tapping screws;

[0005] 2. Inlay nuts in the manifold and fix them with bolts;

[0006] However, in both of these fixing methods, the water pump and the manifold are hard-connected, and the vibration and noise of the water pump will be transmitted through the manifold, affecting the NVH performance. When directly adding a rubber shock absorption pad between the water pump and the manifold and fixing it with bolts, the bolt will be subjected to a reverse force from the shock absorption pad when tightened. Part of the tightening force needs to overcome the reaction force of the shock absorption pad deformation, and the torque will decay, making it impossible to effectively control the torque and ensure consistency, and it is difficult to implement industrially. Summary of the Utility Model

[0007] In order to solve the above technical problems, the utility model provides a shock absorption and fixing structure for a water pump and a manifold of a thermal management module, which improves the shock absorption effect of the installation of the water pump installation kit, improves the consistency when the fixing components are installed and tightened, and is convenient to meet the use requirements.

[0008] A shock-absorbing and fixing structure for a water pump and a manifold of a thermal management module of the present utility model includes a manifold, an electric water pump, and a water pump mounting kit. The water pump mounting kit is arranged on the outer side wall of the electric water pump, and the electric water pump is mounted on the manifold through the water pump mounting kit. It further includes a fixing component and a shock-absorbing pad. A positioning groove is provided on the manifold. The lower part of the fixing component is mounted in the positioning groove of the manifold. The water pump mounting kit is mounted on the upper part of the fixing component. A stepped surface is provided on the fixing component. The shock-absorbing pad is sleeved on the outer side wall of the fixing component and is arranged between the manifold and the water pump mounting kit. Mount the lower part of the fixing component in the positioning groove of the manifold, sleeve the shock-absorbing pad on the outside of the fixing component, then mount the water pump mounting kit on the fixing component and make the bottom of the water pump mounting kit contact the top surface of the shock-absorbing pad, and then fix the position of the water pump mounting kit through the fixing component. By providing the shock-absorbing pad, the shock-absorbing effect of the installation of the water pump mounting kit is improved. By providing a stepped surface on the fixing component, it plays a role of limiting during installation, improves the consistency when the fixing component is installed and tightened, and is convenient to meet the use requirements.

[0009] Preferably, the fixing component includes a threaded insert, a stud, and a nut. The threaded insert is arranged in the positioning groove of the manifold. The lower part of the stud is screwed and fitted inside the threaded insert. The water pump mounting kit and the shock-absorbing pad are respectively sleeved on the outer side wall of the stud. And the bottom end of the shock-absorbing pad contacts the threaded insert and the top end of the manifold, the top end of the shock-absorbing pad contacts the bottom end of the water pump mounting kit. The nut is screwed and fitted on the upper part of the outer side wall of the stud. Mount the threaded insert in the positioning groove of the manifold, then screw and fit the lower part of the stud on the threaded insert, sleeve the shock-absorbing pad and the water pump mounting kit on the outside of the stud in sequence, and then screw the nut on the upper part of the stud to press and fix the water pump mounting kit, so as to position the electric water pump and improve the convenience of the loading and unloading operation of the electric water pump.

[0010] Preferably, the stepped surface is arranged on the outer side wall of the stud. By calculating the compressed thickness A of the shock-absorbing pad when it is installed in place and the thickness B of the water pump mounting kit, the height of the stepped surface provided on the stud is A + B. There is no thread on the surface of the stud at the height position of A + B, and there is a thread on the surface of the stud above the height of A + B. Therefore, when the shock-absorbing pad is installed on the stud, mount the water pump mounting kit on the stud and locate it at the top of the shock-absorbing pad, and then screw the nut on the stud to press the water pump mounting kit tightly. When the nut is tightened to the height of A + B, due to the existence of the stepped surface, it plays a limiting role and cannot be tightened further. Therefore, the tightening and consistency of the nut can be ensured to meet the use requirements.

[0011] Preferably, a limiting strip is arranged on the inner side wall of the positioning groove of the manifold, and a groove is arranged on the outer side wall of the threaded insert. The groove is arranged in cooperation with the limiting strip; it improves the anti-slip effect between the threaded insert and the manifold, avoids the situation that the threaded insert rotates and slips in the manifold, and improves the stability of the nut tightening.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: The lower part of the fixing component is installed on the positioning groove of the manifold, the shock pad is sleeved outside the fixing component, then the water pump installation kit is installed on the fixing component, and the bottom of the water pump installation kit is in contact with the top surface of the shock pad. Then, the position of the water pump installation kit is fixed through the fixing component. By setting the shock pad, the shock absorption effect of the installation of the water pump installation kit is improved. By setting a stepped surface on the fixing component, the function of limiting during installation is achieved, and the consistency when the fixing component is installed and tightened is improved, which is convenient to meet the use requirements.
