DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiment of the present application discloses an engine rear suspension.

[0039] Embodiment 1:

[0040] Reference Figure 1 and Figure 2 The engine rear suspension includes a vulcanized body 1 and a metal shield 2. The vulcanized body 1 includes a buffer portion 11 and a connecting portion 12. The buffer portion 11 and the connecting portion 12 are both made of rubber material, and the buffer portion 11 is integrally connected to the upper end of the connecting portion 12.

[0041] The metal shield 2 is made of metal material. Specifically, the metal shield 2 includes a shield body 21 and a plurality of clips 22. The shield body 21 is sleeved on the buffer portion 11 and the lower end thereof abuts against the connecting portion 12. The plurality of clips 22 are integrally connected to the lower end of the shield body 21 and are arranged at intervals along the circumference of the shield body 21. The plurality of clips 22 are clipped to the peripheral side of the upper end of the connecting portion 12 to achieve installation and fixation of the metal shield 2 and the vulcanization body 1.

[0042] In practical applications, the metal shield 2 is abutted against the upper end of the connection part 12 through the cover body 21, and a plurality of buckles 22 are snapped onto the peripheral side of the upper end of the connection part 12 to achieve the installation of the metal shield 2 and the vulcanized body 1. Among them, since the cover body 21 is sleeved on the buffer part 11 to achieve shielding of the buffer part 11, the area of ​​the vulcanized body 1 exposed to the air can be reduced, thereby reducing the dust attached to the outer peripheral side of the vulcanized body 1. At the same time, the cover body 21 can block the oil stains, thereby minimizing the contact between the oil stains and the outer peripheral side of the vulcanized body 1, which can effectively slow down the aging speed of the vulcanized body 1, thereby increasing the service life of the engine rear suspension.

[0043] In some embodiments, the vulcanized body 1 also includes a metal reinforcement portion 13, and the connecting portion 12 is arranged in a circular ring shape. Correspondingly, the metal reinforcement portion 13 is arranged along the circumference of the connecting portion 12, so that the metal reinforcement portion 13 is also arranged in a circular ring shape, and the metal reinforcement portion 13 is embedded in the connecting portion 12. Since the metal reinforcement portion 13 is made of metal material, the stiffness and connection strength of the connecting portion 12 are improved, so that the overall stiffness and strength of the engine rear suspension are strong.

[0044] Reference Figure 2 and Figure 3 In some embodiments, the upper end of the metal reinforcement portion 13 extends toward the outer peripheral side and protrudes from the connecting portion 12, so that each clip 22 is snapped into the metal reinforcement portion 13. The metal reinforcement portion 13 has a certain strength, which can ensure the snapping strength of the clip 22 to improve the stability of the installation of the metal shield 2, and also avoid the clip 22 being directly snapped into the connecting portion 12, causing the connecting portion 12 to deform, thereby affecting the normal operation of the vulcanization body 1, that is, improving the stability of the operation of the vulcanization body 1.

[0045] In some embodiments, the metal shield 2 is made of iron material to ensure the overall structural strength of the metal shield 2 and to enable the buckle 22 to have a certain elastic deformation ability to facilitate the buckle 22 to be snapped in. In other embodiments, the metal shield 2 can also use aluminum material of a certain thickness.

[0046] Reference Figure 1 and Figure 2 In some embodiments, the cover body 21 is formed with a plurality of reinforcement protrusions 23 by pressing from the inside outward. This embodiment is described by taking two reinforcement protrusions 23 as an example. The two reinforcement protrusions 23 are evenly spaced along the circumference of the cover body 21 to improve the overall structural strength of the metal shield 2. Among them, since the reinforcement protrusions 23 are formed by pressing from the inside outward, the internal space of the cover body 21 can be guaranteed, thereby ensuring that the size of the cover body 21 is small.

[0047] In some embodiments, the engine rear suspension further includes a metal bracket 3, and the lower end of the connection portion 12 is fixedly connected to the metal bracket 3. The connection portion 12 is fixedly connected to the metal bracket 3 in a manner that is not limited to plugging, bolting, etc., as long as the connection portion 12 can be stably fixed to the metal bracket 3. At the same time, the metal bracket 3 is used to be fixedly connected to the vehicle frame, so that the engine rear suspension is installed on the vehicle frame.

[0048] The implementation principle of this embodiment is as follows: in actual application, the metal shield 2 is abutted against the upper end of the connection part 12 through the cover body 21 and a plurality of buckles 22 are snapped on the peripheral side of the upper end of the connection part 12 to realize the installation of the metal shield 2 and the vulcanized body 1. Among them, since the cover body 21 is sleeved on the buffer part 11 to achieve shielding of the buffer part 11, the area of ​​the vulcanized body 1 exposed to the air can be reduced, thereby reducing the dust attached to the outer peripheral side of the vulcanized body 1. At the same time, the cover body 21 can block the oil stains, thereby minimizing the contact between the oil stains and the outer peripheral side of the vulcanized body 1, so that the aging speed of the vulcanized body 1 can be effectively slowed down, thereby increasing the service life of the engine rear mount.

[0049] Embodiment 2:

[0050] Reference Figure 4 The other structures of this embodiment are the same as those of embodiment 1, except that the engine rear suspension further includes a plurality of fastening components 4, the number of the fastening components 4 is the same as the number of the buckles 22, and each fastening component 4 is arranged on each buckle 22.

[0051] Reference Figure 4 and Figure 5 Specifically, the fastening assembly 4 includes a fastening plate 41, a connecting seat 42 and a spring 43. The fastening plate 41 is an arc plate and is located on the side of the buckle 22 close to the connecting portion 12. The connecting seat 42 is arranged in a "T" shape. One end of the connecting seat 42 in the shape of a rectangular plate is located on the side of the buckle 22 away from the connecting portion 12, and one end of the connecting seat 42 in the shape of a round rod is movably inserted into the buckle 22 and fixedly connected to the side of the fastening plate 41 close to the buckle 22. One end of the spring 43 is fixedly connected to the side of the buckle 22 away from the fastening plate 41, and the other end is fixedly connected to the connecting seat 42, so as to drive the connecting seat 42 to move toward the connecting portion 12, so that the fastening plate 41 abuts against the connecting portion 12, which can further improve the stability of the metal shield 2 being clamped on the vulcanized body 1.

[0052] Among them, during the installation of the metal shield 2, after the cover body 21 is sleeved on the buffer part 11, the connecting seat 42 is pulled outward to make the fastening plate 41 fit against the buckle 22, so that the fastening plate 41 can pass through the metal reinforcement part 13, so that the buckle 22 can be snapped into the outer peripheral side of the metal reinforcement part 13, and then the connecting seat 42 is loosened to achieve the abutment of the fastening plate 41 against the connecting part 12, which is simple and convenient to operate.

[0053] Reference Figure 5 In some embodiments, a groove 221 is provided on one side of the buckle 22 close to the fastening plate 41. The connecting seat 42 is pulled outward to drive the fastening plate 41 close to the buckle 22 and make the buckle 22 embedded in the groove 221. In this way, the fastening plate 41 can be prevented from protruding out of the buckle 22 and interfering with the metal reinforcement part 13, thereby facilitating the snap-fitting of the buckle 22.

[0054] In some embodiments, a chamfer 411 is provided at the lower end of the fastening plate 41 close to the connecting portion 12. When the chamfer 411 abuts against the outer peripheral side of the metal reinforcement portion 13, the fastening plate 41 can be automatically embedded in the embedding groove 221 under the guiding action of the chamfer 411, thereby further facilitating the snap-fit ​​of the buckle 22.

[0055] In some embodiments, the fastening assembly 4 also includes a limit block 44, one end of which is rotatably connected to the side of the buckle 22 away from the fastening plate 41, and the connecting seat 42 is pulled outward and the limit block 44 is rotated, so that the end of the limit block 44 away from the rotation abuts against the connecting seat 42, so as to limit the spring 43 from driving the fastening plate 41 to move, and also facilitate the clamping of the buckle 22.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
