Description

Technical Field

[0001] The utility model relates to the technical field of karts, in particular to a kart engine vibration double buffer structure. Background Art

[0002] A kart is a vehicle that can travel on any terrain, and can move freely on terrain where ordinary vehicles are difficult to maneuver. Because its structure is very similar to that of a motorcycle, and many parts are common to motorcycles, some people call it a "four-wheeled motorcycle." This type of vehicle has multiple uses and is not restricted by road conditions.

[0003] The engine of the current kart is installed on the frame. As the power output component of the entire kart, the engine has relatively large power and generates relatively large vibrations. These vibrations will be transmitted to the driving seat through the frame. In order to reduce the transmission of vibrations, current technologies such as patent application number CN202020975538.5 disclose a shock-absorbing connection structure for a beach car, which achieves shock absorption through multiple elastic parts. However, this structure has the engine installed on the left and right sides, with no support at the bottom, and is only fixed by connecting seat bolts. It is easy to loosen over time, causing certain safety hazards. At the same time, the vibration is damped by multiple elastic parts, but it relies on lateral buffering for shock absorption, and there is only one, which cannot meet current needs. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a kart engine vibration double buffer structure, which has a simple structure, better shock absorption and buffering effect and higher safety.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] A kart engine vibration double buffer structure comprises an engine bracket and an intermediate connecting seat, wherein a fixing sleeve is welded to the left end of the intermediate connecting seat, and support sleeves are respectively welded to the front and rear ends of the right side of the intermediate connecting seat, and a first buffer pad is built in the fixing sleeve and the support sleeve, and an intermediate sleeve is also placed inside the fixing sleeve and between the two support sleeves, and the intermediate sleeve between the two support sleeves is welded to the intermediate connecting seat, and a second buffer pad is built in the front and rear ends of the intermediate sleeve, and a first locking rod is also placed in the support sleeve, and the first locking rod penetrates the support sleeve and the first buffer pad in the intermediate sleeve and the second buffer pad is locked and fixed relatively, and a second locking rod is also placed in the fixing sleeve, and the second locking rod penetrates the fixing sleeve and the first buffer pad in the intermediate sleeve and the second buffer pad is locked and fixed relatively.

[0007] A further technical solution is that a limiting sleeve is also placed in the middle sleeve, and the limiting sleeve is located between the second buffer pads on the front and rear sides of the middle sleeve, and is used to limit the second buffer pad in the front and rear positions and prevent it from moving on the first locking rod or the second locking rod.

[0008] A further technical solution is that an engine connecting rod and a bottom support plate are also welded to the middle connecting seat, as shown in FIG. 8 , for supporting the engine.

[0009] A further technical solution is that a bottom connecting plate is welded on the engine bracket and below the fixing sleeve, and two or more bolts are threadedly connected to the bottom connecting plate to support the middle sleeve at the side end of the fixing sleeve. Of course, the middle sleeve at the side end of the fixing sleeve can also directly contact the engine bracket.

[0010] The beneficial effects of the utility model are as follows: the utility model provides a kart engine vibration double buffer structure, a second buffer pad is installed in the middle sleeve, and a first buffer pad is installed in the support sleeve and the fixed sleeve. The vibration force generated by the engine is buffered twice by the first buffer pad and the second buffer pad before reaching the engine bracket, which has a double buffer effect. Compared with the existing single buffer, it can better reduce the vibration force and improve the comfort. At the same time, the engine is supported by the bottom of the middle connecting seat to avoid loosening of the bolt connection caused by long-term vibration, avoid safety hazards, and improve safe use.

[0023] A limiting sleeve 11 is also placed in the middle sleeve 2. The limiting sleeve 11 is located between the second buffer pads 10 on the front and rear sides of the middle sleeve 2 to limit the second buffer pads 10 at the front and rear positions and prevent them from moving on the first locking rod 12 or the second locking rod 14. The engine connecting rod 4 and the bottom support plate 3 are also welded to the middle connecting seat 13. Figure 8 As shown, it is used to support the engine 15. A bottom connecting plate 6 is welded on the engine bracket 1 and below the fixing sleeve 5. Two or more bolts 7 are threadedly connected to the bottom connecting plate 6 to support the middle sleeve 2 at the side end of the fixing sleeve 5. Of course, the middle sleeve 2 at the side end of the fixing sleeve 5 can also directly contact the engine bracket 1 or be directly welded to the engine bracket 1.

[0024] In this embodiment, if Figure 1 , Figure 7 and Figure 8 As shown, the engine 15 is installed on the middle connecting seat 13 through the engine connecting rod 4 and the bottom support plate 3. When the vibration generated after the engine 15 is started is transmitted from the left side, it is first transmitted to the fixing sleeve 5. The first buffer pad 9 is built-in inside the fixing sleeve 5. At this time, it plays a first vibration buffering and shock absorbing effect, and the excess vibration will be transmitted to the second locking rod 14. The second buffer pad 10 is sleeved on the second locking rod 14. The vibration on the second locking rod 14 is transmitted to the second buffer pad 10 again, at this time, it plays a second vibration buffering and shock absorbing effect, and finally transmitted from the second buffer pad 10 to the middle sleeve 2, and finally transmitted from the middle sleeve 2 to the engine bracket 1.

[0025] Similarly, if Figure 1 , Figure 7 and Figure 8 As shown, when the vibration generated after the engine 15 is started is transmitted from the right side, it is first transmitted to the middle sleeve 2.

Finally, it is transmitted from the first buffer pad 9 to the support sleeve 8, and finally from the support sleeve 8 to the engine bracket 1.

[0026] Therefore, the engine 15 transmits vibration to the engine bracket 1 after passing through two shock absorbers on the left and right sides, which can greatly reduce the discomfort caused by the vibration.
