Two reinforcing crossbars are provided on the carrier bracket, and two positioning rods are provided on each of the two reinforcing crossbars. The positioning rods are provided with a positioning hole one, which is corresponding to the positioning hole two on the buffer sleeve, and are fixedly connected by the screw and nut.

[0005] Preferably, the buffer sleeve and shockproof connecting bracket are designed with an H-shaped structure, and the front and rear connecting parts are designed with an arc-shaped structure, so that the power source is suspended in the air.

[0006] Preferably, the buffer sleeve is made of rubber, but new composite materials, such as rubber mixed with elastic fibers or specially formulated rubber, can also be used to further improve vibration absorption and damping performance and adapt to more complex vibration conditions.

[0007] Preferably, the front and rear connectors are welded to the buffer sleeve with metal materials or are integrally cast, and their dimensions can be adjusted according to the size of the power source and external carrier, making them suitable for various installation scenarios of power equipment in small and medium-sized vehicles and highly versatile.

[0008] The beneficial effects of this utility model are:

[0009] 1. It has a reasonable structural design, simple operation, and convenient use. It effectively processes, absorbs, attenuates, and isolates the vibration frequency between the power source and the carrier, greatly reducing the abnormal noise caused by vibration when the power source is working, improving the comfort of vehicle use, reducing the continuous impact of vibration on the frame, avoiding structural damage to the frame due to long-term strong vibration, extending the service life of the frame and related parts, reducing maintenance and replacement costs, and is flexible in adaptation. The H-shaped shockproof connection bracket body and buffer sleeve, together with the reinforcing crossbars and positioning rods on the carrier bracket, form a stable connection structure to ensure that the power source is installed firmly and can maintain connection reliability even in a vibration environment.

[0010] 2. This engine anti-vibration connection bracket effectively solves the vibration drawbacks of direct installation of vehicle power sources, and has significant advantages such as vibration reduction, noise reduction, and extended equipment life.

Detailed implementation method:

[0018] like Figures 1-5As shown, this specific embodiment adopts the following technical solution: It includes a power source 1, a positioning screw 2, a shockproof connecting bracket body 3, a carrier bracket 4, a screw 5, and a nut 6. The bottom ends of the power source 1 are respectively provided with a front connector 101 and a rear connector 102, and are fixedly connected to the power source connectors 301 at the front and rear ends of the shockproof connecting bracket body 3 through the positioning screw 2. A buffer sleeve 302 is provided behind the power source connector 301, and buffer sleeves 303 are installed on the left and right sides inside the buffer sleeve 302. Two reinforcing crossbars 401 are provided on the carrier bracket 4, and two positioning rods 402 are provided on each of the two reinforcing crossbars 401. The positioning rods 402 are provided with a positioning hole 4021, which corresponds to the positioning hole 3031 on the buffer sleeve 303, and are fixedly connected through the screw 5 and the nut 6.

[0019] The buffer sleeve 302 and the main body 3 of the shockproof connecting bracket are designed in an H-shape, while the front connector 101 and the rear connector 102 are designed in an arc shape, so that the power source 1 is suspended in the air.

[0020] The buffer sleeve 203 is made of rubber, or it can be made of new composite materials, such as rubber mixed with elastic fibers or specially formulated rubber, to further improve vibration absorption and damping performance and adapt to more complex vibration conditions.

[0021] The front connector 101 and the rear connector 102 are welded to the buffer sleeve 302 with metal materials or formed by integral casting. The size can be adjusted according to the size of the power source and external carrier, making it suitable for various installation scenarios of power equipment in small and medium-sized vehicles and highly versatile.

[0022] The working principle of this specific embodiment is as follows: The front connector 101 and the rear connector 102 at both ends of the power source 1 are placed inside the power source connector 301 at both ends of the anti-vibration connecting bracket body 3, and are fastened by the positioning screw 2 and nut. The force generated by the vibration of the power source 1 is transmitted from the power source connector 301 at both ends of the anti-vibration connecting bracket body 3 to the buffer sleeves 303 on the left and right sides inside the buffer sleeve 302. With the help of the rubber properties of the buffer sleeve 303, the mechanical vibration frequency of the power source 1 (motor, engine) is processed, absorbed, attenuated and isolated to avoid resonance with other carriers (frame, etc.).

[0023] The assembly process of this specific embodiment is as follows: 1. Align the front connector 101 and rear connector 102 at both ends of the bottom of the power source 1 with the power source connector 301 at both ends of the shockproof connecting bracket body 3, insert the positioning screw 2 and fix it with the nut, so that the power source 1 is initially connected to the shockproof connecting bracket body 3; 2. Install the buffer sleeve 303 into the left and right sides of the buffer sleeve 302, align the buffer sleeve 302 with the positioning rod 402 on the carrier bracket 4, insert the screw 5 and fix it with the nut 6, so as to complete the connection between the buffer sleeve 302 and the carrier bracket 4. At this time, the shockproof connecting bracket body 3 and the buffer sleeve 302 form an H-shaped stable structure, and the power source 1 is in a suspended state; 3. Check whether each connection part is firm, and ensure that when the power source 1 vibrates, it can be transmitted to the buffer sleeve 303 through the front connector 101 and rear connector 102 to realize the functions of vibration treatment and absorption.

[0024] This specific embodiment uses a screw and nut connection method, which requires tools for installation and maintenance. Alternatively, a quick-connect structure, such as a snap-fit ​​or flexible pin, can be used to improve assembly efficiency and lower the barrier to entry.

[0025] This specific implementation method features a reasonable structural design, simple operation, and convenient use. It effectively processes, absorbs, attenuates, and isolates the vibration frequency between the power source and the carrier, significantly reducing abnormal noise caused by vibration during power source operation, improving vehicle comfort, reducing the continuous impact of vibration on the chassis, preventing structural damage to the chassis due to long-term strong vibration, extending the service life of the chassis and related components, reducing maintenance and replacement costs, and offering flexible adaptation. The H-shaped shockproof connection bracket body and buffer sleeve, together with the reinforcing crossbars and positioning rods on the carrier bracket, form a stable connection structure, ensuring the power source is firmly installed and maintaining connection reliability even in vibration environments. It effectively solves the vibration drawbacks of direct installation of vehicle power sources in existing systems, and has significant advantages such as vibration reduction, noise reduction, and extended equipment life. Furthermore, its performance and practicality can be further improved through continuous optimization of materials and connection structures, making it suitable for installation applications in various small and medium-sized vehicle power systems.
