[0002] The engine mounting brackets are installed on the left and right sides of the engine block. One end of the mounting cushion is connected to the mounting bracket, and the other end is connected to the vehicle frame, playing a role in buffering and vibration isolation between the engine and the vehicle frame. The existing brackets are in the form of integral casting or welding. After the bracket is made, the installation angle of the mounting cushion is fixed. When the engine needs to be matched with different vehicle models with different installation angles, the bracket needs to be redesigned. In addition, when testing the vibration isolation rate of the mounting cushion by changing the installation angle during the development process, many brackets with different angles also need to be designed and replaced, resulting in a long development cycle and high costs. Summary of the Invention

The first limiting plate is provided with a first limiting groove, and the second limiting plate is provided with a second limiting groove. A first sliding shaft passing through the first limiting groove and the second limiting groove is slidably arranged between the two upper chutes. A clamping structure is arranged between the first sliding shaft and the mounting plate for the mounting cushion. A second sliding shaft passing through the first limiting groove and the second limiting groove is slidably arranged between the two lower chutes. Locking members are arranged at both ends of the first sliding shaft and the second sliding shaft.

[0005] Further, the clamping structure includes a clamping groove arranged on the mounting plate for the mounting cushion and clamping teeth arranged on the periphery of the first sliding shaft and corresponding to the clamping groove. One end of the clamping groove is provided with a relief groove, and the width of the relief groove is greater than the width of the clamping groove.

[0006] Furthermore, the clamping groove is a rectangular groove, and correspondingly, the clamping teeth are rectangular teeth.

[0007] Furthermore, both the first sliding shaft and the second sliding shaft include an intermediate shaft section. Locking sections are respectively arranged at both ends of the intermediate shaft section. The diameter of the intermediate shaft section is greater than the diameter of the locking section, and the clamping teeth are located on the intermediate shaft section.

[0008] Furthermore, the width of the first limiting groove is greater than the diameter of the middle shaft section, and the width of the second limiting groove is less than the diameter of the middle shaft section.

[0009] Furthermore, the locking section extends to the outside of the side plate, and the locking member is a nut threadedly connected to the locking section.

[0010] Furthermore, an axially arranged notch is provided on the periphery of the locking section, and the notch is slidably connected to the side wall of the sliding groove.

[0011] Furthermore, the sliding groove is a straight groove or an arc groove.

[0012] Furthermore, the bottom plate is provided with a reinforcing plate connecting the side plates.

[0013] Furthermore, the two side plates are parallel to each other, and the bottom plate is provided with a plurality of through holes for connecting the engine body.

[0014] Beneficial Effects

[0015] Compared with the prior art, the beneficial effects of the adjustable engine mount bracket of the present invention are as follows:

Detailed implementation manners

[0025] The present invention will be further described below in conjunction with specific embodiments in the accompanying drawings.

[0026] Refer to Figures 1-6 , an adjustable engine suspension bracket, including a bottom plate 1, on which a plurality of through holes are provided, and the bottom plate 1 can be fixed to the engine body by passing bolts through these through holes. On one side of the bottom plate 1, two side plates 2 arranged at intervals are fixedly connected. The side plates 2 are provided with two sliding grooves 3 arranged at intervals up and down. Between the two side plates 2, there is a suspension mounting plate 4. On both sides of the back of the suspension mounting plate 4, there are respectively a first limiting plate 41 and a second limiting plate 42. The first limiting plate 41 is provided with a first limiting groove 43, and the second limiting plate 42 is provided with a second limiting groove 44. A first sliding shaft 5 passing through the first limiting groove 43 and the second limiting groove 44 is slidably arranged between the two upper sliding grooves 3. There is a clamping structure between the first sliding shaft 5 and the suspension mounting plate 4, and the clamping structure is beneficial to arbitrarily adjusting the angle of the suspension mounting plate within a certain range. A second sliding shaft 6 passing through the first limiting groove 43 and the second limiting groove 44 is slidably arranged between the two lower sliding grooves 3. Locking members 7 are provided at both ends of the first sliding shaft 5 and the second sliding shaft 6. By adjusting the relative positions of the first sliding shaft 5 and the second sliding shaft 6 and clamping the first sliding shaft 5 and the suspension mounting plate 4 through the clamping structure, the angle of the suspension mounting plate 4 can be arbitrarily adjusted within the range of 0 - 90°. When the engine needs different installation angles for different vehicle models, there is no need to redesign the bracket. In addition, it is also very convenient and efficient to change the installation angle during the development process to test the vibration isolation rate of the suspension cushion, etc., greatly reducing the number of parts and the development cycle.

[0027] In this embodiment, the clamping structure includes a card slot 8 provided on the suspension mounting plate 4 and engaging teeth 52 provided on the periphery of the first sliding shaft 5 and corresponding to the card slot 8. One end of the card slot 8 is provided with a relief groove 81, and the width of the relief groove 81 is greater than the width of the card slot 8.

[0028] In this embodiment, the card slot 8 is a rectangular slot, and correspondingly, the engaging teeth 52 are rectangular teeth.

[0029] In this embodiment, the first sliding shaft 5 and the second sliding shaft 6 both include an intermediate shaft section 51 , and locking sections 61 are respectively provided at both ends of the intermediate shaft section 51 . The diameter of the intermediate shaft section 51 is larger than the diameter of the locking section 61 , and the latching teeth 52 are located in the intermediate shaft section 51 .

[0030] In this embodiment, the width of the first limiting groove 43 is greater than the diameter of the middle shaft section 51, and the width of the second limiting groove 44 is less than the diameter of the middle shaft section 51, which is beneficial to the sliding of the sliding shaft and allows the angle of the suspension mounting plate to be better adjusted.

[0031] In this embodiment, the locking section 61 extends to the outside of the side panel 2, and the locking piece 7 is a nut threadedly connected to the locking section 61. After adjusting the relative positions of the first sliding shaft 5 and the second sliding shaft 6, the nut is used to lock them, thereby improving the stability of the suspension bracket.

[0032] In this embodiment, an axially arranged notch 62 is provided on the periphery of the locking section 61, and the notch 62 is slidably connected to the side wall of the slide groove 3. The notch 62 can limit the rotation of the locking section 61, so that the first sliding shaft 5 and the second sliding shaft 6 can only move translationally and axially along the slide groove 3 but cannot rotate, which makes it more convenient to adjust the suspension mounting plate 4.

[0033] In this embodiment, the slide groove 3 is a straight groove or an arc groove, which increases the diversity of the suspension bracket and has a wider range of applications.

[0034] In this embodiment, the bottom plate 1 is provided with a reinforcing plate 9 connected to the side plate 2, and the side plate 2 and the reinforcing plate 9 form a barrel shape on the bottom plate 1, so that the suspension bracket is more solid and stable.

[0035] In this embodiment, the two side panels 2 are parallel to each other, the bottom plate is provided with a plurality of through holes for connecting to the engine body, and the corresponding slide grooves 3 on the side panels 2 are also parallel to each other, which is beneficial to the axial sliding of the sliding shaft, improves the integrity of the suspension bracket, and facilitates the angle adjustment of the suspension mounting plate 4.

[0036] The adjustment process is:

[0037] Loosen the locking piece 7, the first sliding shaft 5 moves axially, so that the latch tooth 52 moves to the clearance groove 81, adjust the relative position of the first sliding shaft 5 and the second sliding shaft 6, and adjust the suspension mounting plate 4 to a specified installation angle. The first sliding shaft 5 moves axially, so that the latch tooth 52 is inserted into the latch groove 8 to limit the suspension mounting plate 4, and then the locking piece 7 is locked. The adjustment is simple and convenient.

[0038] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect and practicality of the implementation of the present invention.
