Description

Technical Field

[0001] The present invention belongs to the technical field of engines, and particularly relates to an engine support assembly for a new energy hybrid vehicle. Background Art

[0002] The engine is a very important component in modern automobiles and can stably provide power for the movement of the vehicle. It mainly drives the external connecting rod to work and drives the components on the side to operate through the reciprocating movement of the pistons in the engine. Currently, the engine is generally directly installed on the support beam of the vehicle chassis through an engine support, and the engine support mainly consists of a metal connecting arm and an engine gasket.

[0003] The connecting arm of the engine support is generally of a rigid structure to ensure the stability of the connection between the engine and the external components. An engine gasket is installed on the connecting arm of the chassis, and the engine gasket is connected to the chassis support beam of the engine. The engine gasket plays a role in shock absorption during the operation of the engine.

[0004] The current engine can stably support and fix the engine during actual use, but there are certain problems in actual use. Specifically, the pressure generated during the operation of the engine is basically borne by the engine gasket, and it is basically a rigid connection, which easily leads to the problem of fracture at the connection between the engine gasket and the support beam, reducing the service life of the engine gasket and affecting the normal use of the engine support assembly of the new energy hybrid vehicle.

[0010] As a preferred technical solution of the present invention, the cavity of the second sealing oil cylinder communicates with the cavity of the first sealing oil cylinder. When the first push rod slides into the first sealing oil cylinder, the liquid inside the first sealing oil cylinder flows into the second sealing oil cylinder, pushing the second push rod to extend.

[0011] As a preferred technical solution of the present invention, the reinforcing member is composed of a side mounting plate and a fixed bottom frame. There are two groups of side mounting plates in total, and the two groups of side mounting plates are symmetrically arranged on both sides of the connection cavity. The bottom end of the side mounting plate is fixedly installed with a fixed bottom frame, and a reinforcing hole for reinforcing the support beam is opened on the fixed bottom frame.

[0012] As a preferred technical solution of the present invention, a connecting force arm is installed at the bottom end of the side mounting plate, and the connecting force arm is connected to the side wall of the bottom support plate.

[0013] As a preferred technical solution of the present invention, a buffer mechanism is further included. The buffer mechanism is installed on the upper surface of the bottom support plate. The buffer mechanism includes a foot pad base, a buffer push-in foot pad, a mounting screw and a mounting nut.

[0016] As a preferred technical solution of the present invention, the installation groove is composed of multiple groups of grooves, which are interconnected, and multiple groups of friction pads are installed on the inner wall of the groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, by setting the calibration mechanism and the buffer mechanism, when the engine shakes between the support beams, the vertical shaking is under the action of the buffer push-in foot pads, reducing the collision force between the bracket main body and the bottom support plate, and reducing the vibration amplitude of the overall engine. And the two groups of push rods with different heights are under the action of the connected sealed oil cylinders, realizing that the two groups of pushes alternately push and clamp the engine, achieving the rapid calibration and positioning of the engine, changing the traditional rigid connection and support method by the engine gasket and the connecting arm, and improving the stability and safety of the engine during actual use.

[0018] In the present invention, through the bracket main body and the reinforcement members, the engine main body can be quickly and stably placed in the bracket main body, and the multiple groups of friction pads installed in the installation groove can protect the bottom end of the engine, preventing the bottom end of the engine from rubbing and colliding with the support plate main body during the shaking process, affecting the overall operation stability of the engine. And the cooperation of multiple components in the reinforcement members provides support for the installation of the bracket assembly main body, enabling the bracket assembly to be stably installed on the support beam on the chassis, assisting in fixing the overall bracket assembly, and improving the stability of the overall use of the bracket assembly.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation mode of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0027] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation mode of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] As Figure 1 and Figure 2 shown, it is a schematic structural diagram of the engine support assembly of the new energy hybrid vehicle in this embodiment. The engine support assembly of the new energy hybrid vehicle includes a bracket main body 1, a bottom support plate 2 and a reinforcement member 3. Bottom support plates 2 are symmetrically arranged at both bottom ends on both sides of the bracket main body 1, a reinforcement member 3 is arranged on the side of the bottom support plate 2, the reinforcement member 3 is installed on the support beam of the vehicle chassis, and a calibration mechanism 4 is installed on the reinforcement member 3.

[0030] During use, the engine is placed on the bracket main body 1 and fixed to the engine by bolts, so that the bracket main body 1 as a whole provides stable support for the engine. Then, through the use of the reinforcement member 3, the engine and the bracket main body 1 as a whole are installed on the support beam of the chassis, quickly completing the overall reinforcement and installation of the engine, and improving the overall working quality of the equipment.

[0031] As Figure 3 and Figure 4As shown in the figure, it is a schematic structural diagram of the calibration mechanism 4 in this embodiment. The calibration mechanism 4 includes a connection cavity 41, a first sealing oil cylinder 42, a first push rod 43, a first push plate 44, a second sealing oil cylinder 45, a second push rod 46, and a second push plate 47. The connection cavity 41 is fixedly installed on the reinforcement member 3. The first sealing oil cylinder 42 is installed in the connection cavity 41. The end of the output end of the first sealing oil cylinder 42 is installed with the first push rod 43. The end of the first push rod 43 is installed with a first push plate 44 that fits against the side wall of the engine. The upper surface of the connection cavity 41 is installed with the second sealing oil cylinder 45. The output end of the second sealing oil cylinder 45 is installed with the second push rod 46. The end of the second push rod 46 is provided with a second push plate 47. The second push plate 47 fits against the side wall of the engine. The cavity of the second sealing oil cylinder 45 is internally connected to the cavity of the first sealing oil cylinder 42. When the first push rod 43 slides into the first sealing oil cylinder 42, the liquid inside the first sealing oil cylinder 42 flows into the second sealing oil cylinder 45, pushing the second push rod 46 to extend.

[0032] During use, when the engine is running, due to the continuous reciprocating movement of the piston in the engine and the bumps on the road surface during driving, the engine and the bracket main body 1 shake between the support beams. When the engine shakes, the first push plate 44 contracts into the first sealing oil cylinder 42 due to the shaking of the engine. At this time, the liquid inside the first sealing oil cylinder 42 flows into the second sealing oil cylinder 45 due to the overall movement of the first push plate 44. As the liquid inside the second sealing oil cylinder 45 increases, it drives the entire second push rod 46 to extend towards one side of the engine, driving the second push plate 47 to squeeze against the side wall of the engine, realizing the reinforcement of the overall position of the engine.

[0033] Both the second sealing oil cylinder 45 and the first sealing oil cylinder 42 are of a sealed structure. When the first push rod 43 slides inside the first sealing oil cylinder 42, the liquid inside the first sealing oil cylinder 42 is squeezed due to the movement of the first push rod 43. Due to the existence of pressure, the impact force between the first push rod 43 and the first sealing oil cylinder 42 can be reduced.

[0034] When the second push plate 47 is squeezed, the liquid inside the second sealing oil cylinder 45 will also flow into the first sealing oil cylinder 42, driving the first push plate 44 to flow towards the side close to the engine, realizing the movement and reset of the first sealing oil cylinder 42. The different movement distances of the second push plate 47 will drive the first push plate 44 to move a greater distance, facilitating the first push plate 44 to support and squeeze against the side wall of the engine, and facilitating the first push plate 44 and the second push plate 47 to support and position the engine.

[0035] By setting and squeezing multiple groups of push plates, it is possible to prevent the engine from colliding with the support beam on the chassis during shaking, reduce abnormal noises during driving, and the use of push plates changes the traditional rigid connection and support methods, improving the safety of the overall use of the bracket assembly.

[0036] As shown by the appendix Figure 4 As shown, the calibration mechanism 4 further includes a connection component 48, which is composed of a rotating bracket and a fixing screw. A rotating bracket is fixedly installed on the side of the second push plate 47. The rotating bracket is rotatably connected to the end of the second push rod 46. Thread grooves are jointly opened inside the rotating bracket and the second push rod 46. A fixing screw is threadedly installed inside the thread groove, and an extrusion nut is threadedly installed at the end of the fixing screw.

[0037] During use, the rotating bracket is attached to the end of the second push rod 46, and then the fixing screw is turned into the rotating bracket so that the fixing screw penetrates through the rotating bracket and the second push rod 46 at the same time. Then, the extrusion nut is installed at the end of the fixing screw. By continuously squeezing with the extrusion nut, both sides of the rotating bracket are squeezed to lock the angle and position of the second push plate 47, facilitating the adjustment and change of the angle of the second push plate 47.

[0038] The overall structure and shape of the second push plate 47 can be quickly replaced according to the different contact parts with the engine, enabling the second push plate 47 to fit as closely as possible to the side of the engine, improving the stability of the support of the second push plate 47.

[0039] In this embodiment, anti-slip and buffering rubber pads are installed on the surfaces of both the second push plate 47 and the first push plate 44 to reduce the rigid contact between the second push plate 47, the first push plate 44 and the side wall of the engine, and prevent the problem of damage to the side wall of the engine due to the extrusion of the two groups of push plates.

[0040] As shown by the appendix Figure 4 and Figure 5 As shown, the reinforcement member 3 is composed of side mounting plates 31, a fixed chassis 32 and a connecting force arm 33. There are two groups of side mounting plates 31, and the two groups of side mounting plates 31 are symmetrically arranged on both sides of the connecting cavity 41. A fixed chassis 32 is fixedly installed at the bottom end of the side mounting plate 31. Reinforcement holes for reinforcing the support beam are opened on the fixed chassis 32. A connecting force arm 33 is installed at the bottom end of the side mounting plate 31, and the connecting force arm 33 is connected to the side wall of the bottom support plate 2.

[0041] During use, through the use of two sets of side mounting plates 31, the overall components of the calibration mechanism 4 are supported and fixed. The fixed chassis 32 is in direct contact with the support beam on the chassis, and by using the reinforcement holes, the overall components of the reinforcement member 3 are reinforced and locked. Through the connection and use of the connecting force arm 33, the bottom support plate 2 is stably connected to the reinforcement member 3, providing support for the bottom support plate 2 and the components on the surface of the bottom support plate 2.

[0042] As shown by the appended Figure 5 figures, it further includes a buffer mechanism 5. A buffer mechanism 5 is installed on the upper surface of the bottom support plate 2. The buffer mechanism 5 includes a footpad base 51, a buffer push-in footpad 52, a mounting screw 53, a mounting nut 54, and a reinforcement wing plate 55. The footpad bases 51 are symmetrically installed on the upper surface of the bottom support plate 2. The buffer push-in footpad 52 is installed on the upper surface of the footpad base 51. The mounting screw 53 is installed at the top end of the buffer push-in footpad 52. A plugging groove for plugging the mounting screw 53 is provided on the bracket main body 1. The mounting nut 54 is threadedly installed at the end of the mounting screw 53. The reinforcement wing plates 55 are symmetrically and fixedly installed on both sides of the footpad base 51. The reinforcement wing plates 55 are attached to the side of the bottom support plate 2, and the reinforcement wing plates 55 are connected to the bottom support plate 2 by bolts.

[0043] During use, the mounting screw 53 is inserted into the plugging groove on the bracket main body 1 to complete the preliminary positioning of the bracket main body 1. Then, the mounting nut 54 is rotated. By using the cooperation between the mounting nut 54 and the mounting screw 53, the overall position of the bracket main body 1 is locked and reinforced. When the engine and the bracket main body 1 as a whole shake due to the vehicle's driving, they will move towards one side of the buffer push-in footpad 52. At this time, the bottom end of the bracket main body 1 collides with the surface of the buffer push-in footpad 52. The buffer push-in footpad 52 is an existing buffer pad anti-slip and shock-absorbing TPE push-in footpad, which can reduce the impact force between the bracket main body 1 and the bottom support plate 2 and improve the overall stability of the bracket.

[0044] The reinforcement wing plates 55 can stably move the footpad base 51 and the components on the surface of the footpad base 51, facilitating subsequent stable maintenance and adjustment.

[0045] As shown by the appended Figure 6 figures, this is a schematic structural diagram of the bracket main body 1 in this embodiment. The bracket main body 1 includes a support plate main body 11, a mounting groove 12, and a friction pad 13. The support plate main body 11 is arranged between the bottom support plates 2. The mounting groove 12 matching the contour of the engine is provided on the support plate main body 11. The mounting groove 12 is composed of multiple groups of grooves, which are interconnected with each other. Multiple groups of friction pads 13 are installed on the inner wall of the grooves.

[0046] During use, the engine body is installed in the installation groove 12, and the friction pad 13 is used to protect the bottom end of the engine, preventing the bottom end of the engine from rubbing and colliding with the support plate body 11 during shaking, which affects the overall operation stability of the engine. The overall structure of the support plate body 11 can assist in the quick and convenient installation and reinforcement of the engine.

[0047] The above content is a further detailed description of the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or replacements can still be made, which should all be regarded as belonging to the protection scope determined by the claims submitted for the present invention.
