Description

Technical Field

[0001] This utility model relates to the field of automotive powertrain technology, specifically to a powertrain mounting structure that is easy to disassemble and assemble. Background Technology

[0002] The powertrain mounting structure refers to a series of components and designs that fix and mount the vehicle's powertrain (usually including the engine, transmission, and related accessories) to the frame or body. Its main purpose is to ensure the stability and safety of the powertrain during vehicle operation.

[0003] For example, patent CN221188101 U describes a powertrain mounting device. The described solution involves pre-installing the other end of the motor bracket with the powertrain, meaning the other end of the motor bracket is first fixedly connected to the vehicle's powertrain. One end of the suspension bracket is also first fixed to the vehicle beam via a suspension connecting plate. The powertrain is then lowered from above the vehicle beam onto the suspension bracket, and the other end of the suspension bracket is connected to one end of the motor bracket via a flexible support, thus fixing the powertrain to the vehicle beam. When disassembling the vehicle's powertrain, the other end of the suspension bracket is disconnected from the bottom of the suspension connecting plate. At this point, the suspension bracket, motor bracket, and flexible support are removed together with the powertrain from under the vehicle beam, allowing the powertrain to be repaired.

[0004] In the above cases, the installation and disassembly of the fixed bracket and frame are not convenient, which may increase the difficulty and time of operation. At the same time, when the powertrain is installed on the bracket, it is not easy to disassemble quickly, and the operation is complicated, which may increase the difficulty of installation.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, such as Figures 1-4As shown, the powertrain mounting structure, which facilitates disassembly and assembly, includes: a frame 100, a bracket 200, and a powertrain 300. The bracket 200 is located below the frame 100, and the powertrain 300 is located between two brackets 200. Connecting plates 301 are provided on both sides of the powertrain 300. A locking plate 302 is movably connected to the bottom of the bracket 200. Several connecting posts 303 are fixedly connected to the top of the locking plate 302. A wedge-shaped block 304 is provided at the top of each connecting post 303. The wedge-shaped block 304 is slidably connected to the interior of the bracket 200. The bottom of the connecting plate 301 is provided with a wedge-shaped groove 305 corresponding to the position of the wedge-shaped block 304. A first spring 306 is provided between the support 200 and the bracket 200. A fixing component for fixing the support 200 is provided on one side of the support 200. By sliding the power assembly 300 within the two supports 200, the connecting plate 301 slides on the inner bottom wall of the support 200. When the connecting plate 301 contacts the wedge block 304, the power assembly 300 continues to move. At this time, the connecting plate 301 presses the wedge block 304 downward, and drives the first spring 306 and the connecting column 303 to press downward. When the wedge groove 305 passes the wedge block 304, the wedge block 304 is released and stuck in the wedge groove 305, making it unable to move backward and only able to move forward, thus fixing the power assembly 300 on the support 200.

[0028] In one embodiment, such as Figure 4 As shown, the fixing assembly includes a pressing post 401, which is slidably connected to the interior of the bracket 200. A first limiting ring 402 is slidably connected to the outer wall of the pressing post 401 and is fixedly connected to the interior of the bracket 200. A second limiting ring 409 is fixedly connected to the outer wall of the pressing post 401 away from the first limiting ring 402 and is slidably connected to the interior of the bracket 200. A round-headed locking block 403 is installed on the side of the pressing post 401 near the power assembly 300. The outer wall of the pressing post 401... An arc-shaped block 404 is slidably connected to the upper part of the frame 100. A third limiting ring 405 is movably connected to the side of the arc-shaped block 404 away from the round head block 403. The third limiting ring 405 is fixedly connected to the outer wall of the pressing column 401. A wedge-shaped block 406 is slidably connected to the inside of the frame 100. A second spring 407 is fixedly connected to the top of the wedge-shaped block 406. The top of the second spring 407 is fixedly connected to the inside of the frame 100. A fixing post 408 is also provided on the top of the wedge-shaped block 406. The top of the fixing post 408 is slidably connected to the second spring 407.

[0029] By pressing the pressing post 401 inward, the pressing post 401 slides within the bracket 200, simultaneously moving the second limiting ring 409 and the round-headed locking block 403. The round-headed locking block 403 then inserts into the frame 100, compressing the wedge-shaped locking block 406 inside the frame 100. This compresses the second spring 407 and the fixing post 408, causing them to retract to both sides. When the round-headed locking block 403 moves away from the wedge-shaped locking block 406, the wedge-shaped locking block 406 rebounds and locks onto the round-headed locking block 403, thus fixing the bracket 200 to the frame 100. When separation is required... By pressing the pressing post 401 again, the pressing post 401 causes the third limiting ring 405 and the arc-shaped block 404 to approach the wedge-shaped locking block 406. After the arc-shaped block 404 passes the wedge-shaped locking block 406, the wedge-shaped locking block 406 rebounds, causing the right-angled surface of the wedge-shaped locking block 406 to contact the arc-shaped surface of the arc-shaped block 404. At this time, the pressing post 401 is released and pulled outward. Under the push of the wedge-shaped locking block 406, the arc-shaped block 404 approaches and adheres tightly to the round-headed locking block 403. Then, the wedge-shaped locking block 406 slides on the arc surface of the arc-shaped block 404, thereby separating the bracket 200 from the frame 100.

[0030] In one embodiment, such as Figure 4 As shown, the frame 100 has a sliding groove 501 inside that corresponds to the position of the wedge-shaped block 406 and the fixing post 408, which facilitates the movement of the fixing post 408 and the wedge-shaped block 406.

[0031] In one embodiment, such as Figure 4 As shown, the frame 100 also has an movable groove 502 inside that corresponds to the position of the round-headed locking block 403; this allows the round-headed locking block 403 to have sufficient space to move within the movable groove 502.

[0032] In one embodiment, such as Figures 1 to 3 As shown, a baffle 601 is provided on one side of the two brackets 200 that are close to each other; the baffle 601 restricts the upward movement of the power assembly 300.

[0033] In one embodiment, such as Figures 1 to 3 As shown, the inner bottom walls of the two brackets 200 are provided with limiting blocks 602; the moving position of the powertrain 300 is limited by the limiting blocks 602.

[0034] In one embodiment, such as Figures 1 to 3 As shown, the bracket 200 is L-shaped, which facilitates the installation of the powertrain 300.

[0035] In one embodiment, such as Figure 4As shown, the ramp surface of the wedge-shaped block 406 faces the arc-shaped block 404, and both sides of the arc-shaped block 404 are arc surfaces; so that the right-angled surface of the wedge-shaped block 406 can abut against the round-headed block 403 and slide with the arc-shaped block 404.

[0036] The above embodiments disclose a powertrain mounting structure that facilitates disassembly and assembly. By sliding the powertrain 300 within the two brackets 200, the connecting plate 301 slides against the inner bottom wall of the bracket 200. When the connecting plate 301 contacts the wedge block 304, the powertrain 300 continues to move. At this time, the connecting plate 301 presses downward against the wedge block 304, causing the first spring 306 and the connecting post 303 to press downward. When the powertrain 300 moves to the limiting block 602, the powertrain 300 can no longer move further. Moving forward, the wedge groove 305 passes the wedge block 304, releasing the wedge block 304 and locking it in the wedge groove 305, preventing it from moving backward and allowing it to move forward only. This secures the powertrain 300 to the bracket 200. To remove the powertrain 300, simply pull down the locking plate 302. Then, the bracket 200 is installed on the frame 100. By pressing the pressing post 401 inward, the pressing post 401 slides within the bracket 200, simultaneously moving the second limit ring 409. The round-headed locking block 403 moves, then inserts into the interior of the frame 100. This compresses the wedge-shaped locking block 406 inside the frame 100, causing the second spring 407 and the fixing post 408 to retract to both sides. When the round-headed locking block 403 moves away from the wedge-shaped locking block 406, the wedge-shaped locking block 406 rebounds and locks onto the round-headed locking block 403, thus fixing the bracket 200 to the frame 100. When separation is needed, pressing the pressing post 401 again causes the pressing post 401 to drive the third... The limiting ring 405 and the arc-shaped block 404 approach the wedge-shaped locking block 406. After the arc-shaped block 404 passes the wedge-shaped locking block 406, the wedge-shaped locking block 406 rebounds, causing the right-angled surface of the wedge-shaped locking block 406 to contact the arc-shaped surface of the arc-shaped block 404. At this time, the pressing column 401 is released and the pressing column 401 is pulled outward. Under the push of the wedge-shaped locking block 406, the arc-shaped block 404 approaches and adheres tightly to the round-headed locking block 403. Then, the wedge-shaped locking block 406 slides on the arc surface of the arc-shaped block 404, thereby separating the bracket 200 from the frame 100.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
