Description

Technical Field

[0001] This utility model relates to the field of oil pump equipment technology, and in particular to an automotive oil pump support frame. Background Technology

[0002] The function of the oil pump is to increase the oil pressure to a certain level and force it to the moving surfaces of various engine parts. When the engine is running, the drive gear on the camshaft drives the transmission gear of the oil pump, causing the drive gear fixed on the drive gear shaft to rotate, which in turn drives the driven gear to rotate in the opposite direction, sending the oil from the inlet chamber along the tooth gap and pump wall to the outlet chamber. The oil pump pressurizes the oil from the oil pan and delivers it to the oil filter and various lubrication passages to lubricate the main moving parts of the engine and filter the oil.

[0003] During assembly, the oil pump needs to be fixed and reinforced by a support frame. Existing automotive oil pump support frames have poor stability during support. Due to the cylindrical structure of the oil pump, the support frame needs to be fixed by a sleeve method during installation. When sleeved, the fixation at one end of the oil pump needs to be released. After the support frame is installed and fixed on the oil pump, if the fixing points are not aligned, it will affect the subsequent assembly of the oil pump and reduce the practicality of the support frame. Therefore, we propose an automotive oil pump support frame. Utility Model Content

[0004] The problem that this utility model aims to solve is that in the prior art, the oil pump support bracket is prone to misalignment during installation, which affects the connection and assembly of the oil pump, and the stability after fixing is poor.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automotive oil pump support frame, comprising a fixed base, a pump body fixing plate fixed to the top surface of one end of the fixed base, a support tray fixed above the other end of the pump body fixing plate, fixing rods fixed at the four corners of the bottom surface of the support tray, the bottom surfaces of the fixing rods fixed to the top surface of the fixed base, a connecting base plate fixed inside the support tray, a fixed clamping plate and a movable clamping plate symmetrically arranged on the top surface of the connecting base plate, fixed side plates fixed at the upper and lower ends of the fixed clamping plate and the movable clamping plate, the fixed side plates at the bottom surface of the fixed clamping plate fixed to the top surface of the connecting base plate, and limiting sleeves fitted on the fixed side plates at the upper and lower ends of the fixed clamping plate and the movable clamping plate, the upper and lower limiting sleeves being fixed to the fixed side plates by bolts.

[0006] As a preferred embodiment of the automotive oil pump support bracket described in this utility model, the bottom of both the fixed base and the pump body fixing plate is provided with weight reduction grooves, the top surface of the pump body fixing plate is glued and fixed with a shock-absorbing pad, and both ends of the pump body fixing plate and the shock-absorbing pad are symmetrically provided with fixing holes.

[0007] As a preferred embodiment of the automotive oil pump support bracket of this utility model, the bottom surface of the pump body fixing plate on both sides of the fixed base is fixed with a reinforcing sleeve frame, and another shock-absorbing pad is glued to the bottom of the reinforcing sleeve frame. An operation window is opened on the outside of both reinforcing sleeve frames and the other shock-absorbing pad.

[0008] As a preferred embodiment of the automotive oil pump support bracket of this utility model, the bottom surface of the connecting base plate, the outer surface of the side wall, and the inner wall of the support tray are all filled and fixed with shock-absorbing rubber. Limiting top plates are symmetrically fixed on both sides of the top surface of the support tray. Each limiting top plate has another shock-absorbing rubber fixed on its bottom surface, and the bottom surface of the other shock-absorbing rubber abuts against the top surface of the connecting base plate.

[0009] As a preferred embodiment of the automotive oil pump support bracket of this utility model, the top joint of the fixed clamp and the movable clamp is set in a Z-shape, and a number of anti-slip pads are fixed at equal intervals on the inner walls of the fixed clamp and the movable clamp. The length of each fixed side plate is equal to the length of the fixed clamp and the movable clamp.

[0010] In a preferred embodiment of the automotive oil pump support bracket described in this utility model, the thickness of the inner part of the limiting sleeve is equal to the sum of the thicknesses of the two fixed side plates, and one end of the limiting sleeve extending to the outside of both the fixed clamping plate and the movable clamping plate is fixed to the side limiting plate.

[0011] In a preferred embodiment of the automotive oil pump support bracket of this utility model, the side limiting plate is configured as a semi-circular shape with the same thickness as the fixed clamping plate and the movable clamping plate, the end of the limiting sleeve away from the side limiting plate is configured as a narrowed inclined shape, and the length of the limiting sleeve is equal to the length of the fixed side plate.

[0012] The beneficial effects of this utility model are as follows: This utility model uses a symmetrical wrap-around clamping method to fix the oil pump. After fixing the pump body rear seat, two clamps are used to fix the pump body branch pipe. Combined with multiple shock-absorbing rubbers, the stability of the oil pump inside the vehicle body can be guaranteed. Moreover, the symmetrical clamping method allows for the assembly of the upper and lower ends of the oil pump first during installation. After assembly, it is fixed by the support frame, avoiding the support frame affecting the accuracy of oil pump assembly. This solves the problems of existing automotive oil pump support frames being prone to misalignment during installation, affecting the connection and assembly of the oil pump, and having poor stability after fixing, thus improving the practicality of the oil pump.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Reference Figures 1-5 This embodiment is an automotive oil pump support bracket, including a fixed base 1. A pump body fixing plate 2 is fixed to the top surface of one end of the fixed base 1, and a support tray 4 is fixed to the top of the other end of the pump body fixing plate 2. Fixing rods 5 are fixed at the four corners of the bottom surface of the support tray 4, and the bottom surfaces of the fixing rods 5 are all fixed to the top surface of the fixed base 1. A connecting base plate 6 is fixed inside the support tray 4. A fixed clamping plate 7 and a movable clamping plate 8 are symmetrically arranged on the top surface of the connecting base plate 6. The upper and lower ends of the fixed clamping plate 7 and the movable clamping plate 8 are fixed with... The fixed side plate 10 and the fixed clamping plate 7 are fixed to the top surface of the connecting base plate 6. The fixed side plate 10 at the upper and lower ends of the fixed side plate 10 of the fixed clamping plate 7 and the movable clamping plate 8 are both fitted with limiting sleeves 11. The upper and lower limiting sleeves 11 are fixed to the fixed side plate 10 by bolts. By clamping the two fixed side plates 10 with the limiting sleeves 11, the fixed clamping plate 7 and the movable clamping plate 8 are clamped and fixed on the oil pump branch pipe, ensuring the firmness of the connection between the fixed clamping plate 7 and the movable clamping plate 8 and the oil pump branch pipe.

[0021] In this embodiment, both the fixed base 1 and the pump body fixing plate 2 have weight-reducing grooves at their bottoms. The presence of these grooves increases the internal friction of the material, thereby consuming more vibration energy and reducing the transmission of vibration energy. A shock-absorbing pad 3 is glued to the top surface of the pump body fixing plate 2. Both ends of the pump body fixing plate 2 and the shock-absorbing pad 3 have symmetrical fixing holes to facilitate fixing the oil pump to the pump body fixing plate 2. Reinforcing frames 15 are fixed to the bottom surfaces of the pump body fixing plates 2 on both sides of the fixed base 1. Another shock-absorbing pad 3 is glued to the bottom of each reinforcing frame 15. An operating window 16 is provided on the outer side of both reinforcing frames 15 and the other shock-absorbing pad 3. The reinforcing frames 15 support the pump body fixing plate 2, making the pump body fixing plate 2 more secure and stable after installation. The operating window 16 facilitates fixing the oil pump to the pump body fixing plate 2.

[0022] In this embodiment, shock-absorbing rubber 14 is filled and fixed between the bottom surface and the outer surface of the side wall of the connecting base plate 6 and the inner wall of the support tray 4. Limiting top plates 13 are symmetrically fixed on both sides of the top surface of the support tray 4. Another shock-absorbing rubber 14 is fixed on the bottom surface of each limiting top plate 13. The bottom surface of the other shock-absorbing rubber 14 abuts against the top surface of the connecting base plate 6 to reinforce the connecting base plate 6 and ensure the shock absorption effect. Through the wrap-around shock-absorbing rubber 14 and the other shock-absorbing rubber 14 above, the connecting base plate 6 can be damped in multiple directions, thereby reducing the transmission of vibration force to the oil pump when the car is running.

[0023] In this embodiment, the top joint of the fixed clamping plate 7 and the movable clamping plate 8 is set in a Z-shape to facilitate the alignment and positioning of the fixed clamping plate 7 and the movable clamping plate 8. Several anti-slip pads 9 are fixed at equal intervals on the inner walls of the fixed clamping plate 7 and the movable clamping plate 8 to increase the friction between the fixed clamping plate 7 and the movable clamping plate 8 and the oil pump, thereby increasing the connection stability in the horizontal direction. The length of each fixed side plate 10 is equal to the length of the fixed clamping plate 7 and the movable clamping plate 8.

[0024] In this embodiment, the thickness inside the limiting sleeve 11 is equal to the sum of the thicknesses of the two fixed side plates 10. This allows the limiting sleeve 11, when fitted onto the two fixed side plates 10, to clamp them together, thereby clamping the fixed clamping plate 7 and the movable clamping plate 8. One end of the limiting sleeve 11 extending to the outside of both the fixed clamping plate 7 and the movable clamping plate 8 is fixed to the side limiting plate 12. The side limiting plate 12 is a semi-circular shape with the same thickness as the fixed clamping plate 7 and the movable clamping plate 8 to prevent side limiting. Plate 12 affects the normal fixation of the oil pump. The end of the limiting sleeve 11 away from the side limiting plate 12 is set to a narrowed inclined shape. The length of the limiting sleeve 11 is equal to the length of the fixed side plate 10. When the limiting sleeve 11 is put on the fixed side plate 10, the end of the limiting sleeve 11 is conveniently put on the outside of the fixed side plate 10. As the limiting sleeve 11 is pushed towards the fixed side plate 10, it can drive the fixed side plate 10 to move relative to each other, thereby driving the fixed clamping plate 7 and the movable clamping plate 8 to clamp the oil pump.

[0025] Working principle: When a support frame is required, first assemble the oil pump inside the vehicle body and connect it. Then, place the pump body fixing plate 2 at the bottom of the oil pump. At this time, the bottom surface of the shock-absorbing pad 3 at the bottom of the reinforcing sleeve 15 is on the bottom of the vehicle body. Fix the oil pump rear seat to the pump body fixing plate 2 with fixing bolts. Then fix the fixing base 1 to the vehicle body. At this time, the fixing clamp 7 is fitted onto the oil pump. After the movable clamp 8 is misaligned with the fixed clamp 7, it is fitted onto the oil pump. Then push the movable clamp 8 to align it with the fixed clamp 7. After alignment, the limiting sleeves 11 are respectively fitted onto the two fixed side plates 10 at the upper and lower ends. Under the guide and push of the ends of the limiting sleeves 11, the two fixed side plates 10 move relative to each other, causing the fixed clamping plate 7 and the movable clamping plate 8 to clamp the oil pump until the side limiting plate 12 abuts against the sides of the fixed clamping plate 7 and the movable clamping plate 8. Then, the bolts are passed through the limiting sleeves 11 and the fixed side plates 10 and fixed with nuts. When the vehicle body vibrates during driving, the shock-absorbing pads 3 and the shock-absorbing rubber 14 can absorb the vibration force and reduce the transmission of the vibration force to the oil pump.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
