Description

Technical Field

[0001] This utility model relates to the field of motor parts technology, and in particular to a lightweight motor end cover. Background Technology

[0002] The motor end cover is a crucial component of the motor. Typically a circular or near-circular disc-shaped structure, it serves two purposes: providing support and fixation, and ensuring a protective seal. Regular inspection and maintenance of the motor end cover are essential for ensuring the motor's normal operation. Inspections include checking for any damage to the end cover's appearance, the integrity of the seal, and the proper functioning of the bearings. In the development of new energy vehicles, achieving lightweight motor design is one of the main ways to improve vehicle power performance.

[0003] For example, the patent publication number CN217769679U, entitled "A Lightweight Motor End Cover," includes a fixing ring, a mounting bracket, a mounting hole, a housing, a reinforcing frame, a filter plate, a through hole, a filter hole, and a baffle. The mounting bracket is welded to the outer edge of the fixing ring, and the mounting bracket has a mounting hole in its middle. The housing is welded to one side of the fixing ring, and the reinforcing frame is welded to the inner wall of the housing. The filter plate is welded to the edge of the housing, and the filter plate has a through hole in its center and a filter hole inside. A baffle is provided on one side of the filter plate, and the baffle is connected to the filter plate by fixing bolts.

[0004] However, in the existing technology, the end cover of the motor plays a protective role for the inside of the motor. In order to meet the motor's usage standards, its end cover is generally designed to be very thick to improve impact resistance. As a result, the overall weight of the motor end cover increases, which is not conducive to improving the power range of new energy vehicles and makes it difficult to meet the future development needs of the automotive industry. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, the end cover of the motor plays a protective role for the inside of the motor. In order to meet the usage standards of the motor, the end cover is generally designed to be very thick to improve the impact resistance, which increases the overall weight of the motor end cover. This is not conducive to improving the power range of new energy vehicles and makes it difficult to meet the development needs of the future automotive industry. Therefore, a lightweight motor end cover is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight motor end cover, comprising a housing mechanism, a support mechanism, and a beam frame mechanism. The housing mechanism includes a cover plate. The support mechanism is distributed at equal intervals along the inner circumference of the cover plate. The support mechanism includes a bent plate. Both ends of the bent plate are fixedly connected to flat plates. Connecting heads are fixedly connected to the surfaces of the two flat plates. A reinforcing rib is fixedly connected between the two connecting heads. A ligament is laid on the outer surface of the reinforcing rib. Both ends of the ligament are fixedly connected to the flat plates. The beam frame mechanism overlaps the outer surface of the ligament. A buffer mechanism is connected between the housing mechanism and the beam frame mechanism.

[0007] Preferably, an ear plate is fixedly connected to the outer wall of the cover plate, and a positioning hole is formed on the surface of the ear plate.

[0008] Preferably, the buffer mechanism includes a connecting column, one end of which is fixedly connected to the beam frame mechanism, and the other end of which passes through the outer wall of the cover plate and is fixedly connected to a circular baffle.

[0009] Preferably, a spring is provided on the outer wall of the connecting column, one end of the spring is fixedly connected to the cover plate, and the other end of the spring is fixedly connected to the beam frame mechanism.

[0010] Preferably, the beam frame mechanism consists of a plurality of circumferential arrays of skeletons, and the outer side wall of the skeleton is fixedly connected with a ring frame.

[0011] Preferably, both ends of the skeleton are fixedly connected to foot support plates, and the skeleton is fixedly connected to the ligaments through the foot support plates.

[0012] Preferably, the outer wall of the spring is coated with a rust inhibitor, and a sealing ring is provided at the center of the surface of the cover plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting multiple sets of support mechanisms around the inner periphery of the cover plate, the support mechanisms are made of materials with certain toughness and strength, which can not only resist the external impact force from the corner of the end cover, but also buffer the internal impact force when the motor is pressed outward, thereby making the thickness of the cover plate thinner. The beam frame mechanism is made with a hollow structure, which meets the impact protection requirements of the motor while realizing the lightweight design of the motor.

[0015] 2. In this utility model, by designing the beam frame mechanism as an umbrella-shaped structure, the ring frame forms a ring support for the skeleton, so that the impact force can be evenly distributed to each part of the skeleton, reducing the mechanical damage caused by excessive impact force. At the same time, foot support plates are set at the bottom corners of the skeleton, which increases the contact area between the skeleton and the ligament, thereby preventing the skeleton from puncturing the ligament and causing damage, improving the service life of the motor end cover and reducing the probability of failure.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1-4As shown, this utility model provides a lightweight motor end cover, including a housing mechanism 1, a support mechanism 2, and a beam frame mechanism 3. The housing mechanism 1 includes a cover plate 11. The support mechanism 2 is distributed at equal intervals along the inner circumference of the cover plate 11. The support mechanism 2 includes a bent plate 21. Both ends of the bent plate 21 are fixedly connected to a flat plate 22. Connecting heads 23 are fixedly connected to the surfaces of the two flat plates 22. A reinforcing rib 24 is fixedly connected between the two connecting heads 23. A ligament 25 is laid on the outer surface of the reinforcing rib 24. Both ends of the ligament 25 are fixedly connected to the flat plate 22. The beam frame mechanism 3 overlaps the outer surface of the ligament 25. A buffer mechanism 4 is connected between the housing mechanism 1 and the beam frame mechanism 3.

[0024] The specific settings and functions of this embodiment are described below. To achieve a lightweight design for the motor end cover, the main body of the housing mechanism 1 is made of aluminum alloy. Aluminum alloy has high strength and low density, and the housing mechanism 1 is die-cast as a whole, controlling the overall thickness of the cover plate 11 and reducing its weight. To improve the protection performance of the motor's internal components, a beam frame mechanism 3 is added inside the cover plate 11. The beam frame mechanism 3 is a hollow structure, which has a certain supporting strength and can also reduce the overall weight. When an external impact occurs, the function of the beam frame mechanism 3 is to prevent the cover plate from impacting the motor. 11 Continuous deformation prevents external stress from damaging the internal structure of the motor. In addition, multiple sets of support mechanisms 2 are set on the inner periphery of the cover plate 11. The support mechanism 2 is made of a material with certain toughness and strength. It can not only resist the external impact force from the corner of the end cover, but also buffer the internal impact force when the motor is pressed outward. At the same time, the support mechanism 2 at the corner of the beam frame mechanism 3 is used as a buffer, so that the self-toughness of the bending plate 21 and the flat plate 22 provides a buffering force, avoiding the problem of the end cover detaching due to impact from the inside.

[0025] Example 2: Figure 2 , Figure 3 and Figure 4 As shown, an ear plate 12 is fixedly connected to the outer wall of the cover plate 11, and a positioning hole 13 is provided on the surface of the ear plate 12. The buffer mechanism 4 includes a connecting column 43, one end of which is fixedly connected to the beam frame mechanism 3, and the other end of which passes through the outer wall of the cover plate 11 and is fixedly connected to a circular baffle 41. A spring 42 is provided on the outer wall of the connecting column 43, one end of which is fixedly connected to the cover plate 11, and the other end of which is fixedly connected to the beam frame mechanism 3. The beam frame mechanism 3 is composed of a circumferential array of multiple skeletons 31, and a ring frame 32 is fixedly connected to the outer wall of the skeleton 31. Both ends of the skeleton 31 are fixedly connected to foot support plates 33, and the skeleton 31 is fixedly connected to the ligament 25 through the foot support plates 33. The outer wall of the spring 42 is coated with an anti-rust agent, and a sealing ring is provided at the center of the surface of the cover plate 11.

[0026] The overall effect of this embodiment is that the beam frame mechanism 3 is similar to an umbrella-shaped structure, and the ring frame 32 forms a ring support for the skeleton 31, so that the impact force can be evenly distributed to each skeleton 31, reducing the mechanical damage caused by excessive impact force. At the same time, foot support plates 33 are set at the bottom corners of the skeleton 31, which increases the contact area between the skeleton 31 and the ligament 25, thereby preventing the skeleton 31 from puncturing the ligament 25 and causing damage. A buffer mechanism 4 is set between the beam frame mechanism 3 and the housing mechanism 1 to buffer the impact force and prevent damage to the internal structure of the motor.

[0027] The usage and working principle of this device are as follows: When an internal impact force hits the end cover, the beam frame mechanism 3 bears the outward impact force, the skeleton 31 transmits the impact force to the spring 42, causing the spring 42 to compress, the connecting column 43 moves to the outside of the cover plate 11, and the sealing ring ensures that the end cover is always sealed during the movement of the connecting column 43. The skeleton 31 moves outward and drives the ligament 25 to be concave and compressed inward, thereby tightening the two ends of the ligament 25 inward, so that the flat plates 22 at both ends are tilted inward, and the bending arc of the bending plate 21 is larger. The toughness of the bending plate 21 forms the self-resetting effect of the skeleton 31.

[0028] When an internal impact force hits the end cap, the cover plate 11 is concave inward, causing the flat plate 22 that fits the circular surface of the cover plate 11 to bend inward. The bending plate 21 bends with a larger arc, and the toughness of the bending plate 21 forms an outward support for the cover plate 11, preventing the cover plate 11 from deforming.

[0029] When the cover plate 11 is excessively deformed, the cover plate 11 contacts the surface of the beam frame mechanism 3, and the structural support of the beam frame mechanism 3 prevents the cover plate 11 from deforming further.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
