[0033] like Figure 1-8 As shown, in one embodiment of this utility model, a brake structure is provided, including a limiting disc 10, a mounting base 20, a limiting rod 30, a brake arm 40, and a reset member 50. The limiting disc 10 is installed inside one of the traveling wheels 60, and the limiting disc 10 is arranged coaxially with the traveling wheel 60. A through hole 12 for a connecting shaft 70 to pass through is provided at the center of the limiting disc 10. The connecting shaft 70 is used to connect the two traveling wheels 60. The limiting disc 10 has a plurality of limiting holes 11, which are arranged in a circular array along the through hole 12. The mounting base 20 is fixedly installed on the frame (not shown in the figure) and located inside the traveling wheel 60. The mounting base 20 has a guide limiting part. The limiting rod 30 is telescopically fitted on the mounting base 20, and the limiting rod 30 can be inserted into any of the limiting holes 11.
[0034] One end of the brake arm 40 is movably connected to the mounting base 20. Specifically, the mounting base 20 is provided with a ball joint adapter 80, and the brake arm 40 is connected to the ball joint adapter 80. The other end of the brake arm 40 is equipped with a pedal 90. The brake arm 40 is connected to the limiting rod 30. The brake arm 40 can move within the guide limiting part to drive the limiting rod 30 into or out of the limiting hole 11. The brake arm 40 can be positioned within the guide limiting part so that the limiting rod 30 remains inserted into the limiting hole 11. A reset member 50 is provided on the mounting base 20. The reset member 50 is used to apply a spring force to the brake arm 40 so that the brake arm 40 tends to move and reset away from the limiting disc 10.
[0035] When braking of the travel wheel 60 is required, the user presses the pedal 90, causing the brake arm 40 to move within the guide limiting part. Simultaneously, the brake arm 40 moves the limiting rod 30 towards the limiting disc 10, inserting the limiting rod 30 into a limiting hole 11 on the limiting disc 10, thereby braking the travel wheel 60. When the brake arm 40 is positioned within the guide limiting part, the limiting rod 30 remains inserted into the limiting hole 11.
[0036] When it is necessary to unlock the travel wheel 60, the user releases the positioning state of the brake arm 40. In this way, the reset component 50 will drive the brake arm 40 to reset, and at the same time, the brake arm 40 will also drive the limit rod 30 to exit the limit hole 11. In this way, the travel wheel 60 is unlocked.
[0037] This embodiment discloses a braking structure that uses the brake arm 40 to engage a limiting rod 30 with a limiting disc 10, thereby restricting the rotation of the travel wheel 60 and achieving braking. Simultaneously, the guide limiting part temporarily positions the brake arm 40, keeping the limiting rod 30 inserted into the limiting hole 11, thus maintaining the braking state of the travel wheel 60. This eliminates the risk of brake failure that occurs with conventional methods relying on tire tread friction, improving safety.
[0038] In one embodiment, the guide limiting portion includes a first guide hole 21 and a second guide hole 22 through which the brake arm 40 passes. The upper end of the first guide hole 21 is inclined away from the limiting disc 10, and the second guide hole 22 extends vertically, with its upper end communicating with the lower end of the first guide hole 21. When the limiting rod 30 is inserted into the limiting hole 11, the brake arm 40 is located within the second guide hole 22.
[0039] After the brake arm 40 is depressed, it moves along the first guide hole 21. Since the first guide hole 21 is inclined, the brake arm 40 will drive the limiting rod 30 to insert into the limiting hole 11 during its movement. When the brake arm 40 moves to the second guide hole 22, since the second guide hole 22 extends vertically, the brake arm 40 will not drive the limiting rod 30 to continue moving towards the limiting disc 10.
[0040] Since the reset member 50 causes the brake arm 40 to tend to move away from the limit plate 10, the reset member 50 will pull the brake arm 40 against the hole wall of the second guide hole 22, thereby temporarily positioning the brake arm 40 in the second guide hole 22. In this way, the limit rod 30 can be kept in the state of extending into the limit hole 11, thereby maintaining the braking state of the travel wheel 60.
[0041] Furthermore, the guide limiting part also includes a limiting protrusion 23 provided on the wall of the second guide hole 22. The limiting protrusion 23 is used to prevent the brake arm 40 from moving towards the first guide hole 21. The limiting protrusion 23 improves the limiting effect on the brake arm 40, preventing the brake arm 40 from disengaging from the second guide hole 22. Of course, in order to allow the brake arm 40 to return to its normal position, the user can push the pedal 90 slightly towards the limiting disc 10. In this way, the brake arm 40 will move around the limiting protrusion 23 and return to the first guide hole 21.
[0042] The design of the guide limit part facilitates the temporary positioning or unlocking of the brake arm 40, making it easy to operate and with a simple and ingenious overall structure.
[0043] In one embodiment, the mounting base 20 is provided with a first side plate 24 on the side away from the limiting plate 10, and the reset member 50 is a tension spring, with both ends of the reset member 50 connected to the brake arm 40 and the first side plate 24 respectively.
[0044] In one embodiment, the end of the limiting rod 30 furthest from the limiting disc 10 is provided with a connecting block 31. The connecting block 31 is located above the brake arm 40 and has a connecting hole 32. The connecting hole 32 has an oblong structure. The brake arm 40 has a connecting post 41, which passes through the connecting hole 32. When the brake arm 40 moves within the first guide hole 21, the connecting post 41 also moves adaptively within the connecting hole 32, thereby driving the limiting rod 30 to extend into or retract from the limiting hole 11, thus realizing the linkage between the limiting rod 30 and the brake arm 40.
[0045] In one embodiment, in order to enable the limiting rod 30 to extend and retract smoothly, the mounting base 20 is provided with a second side plate 25, a guide tube 26 and a support plate 27. The second side plate 25 is close to the limiting plate 10, and the guide tube 26 is connected to the second side plate 25 and the support plate 27 respectively. The limiting rod 30 is movably inserted into the guide tube 26.
[0046] In one embodiment, the top of the mounting base 20 is provided with a relief groove 28 for receiving the connecting shaft 70.
[0047] This embodiment also provides a generator set including the aforementioned braking structure. Because it employs the aforementioned braking structure, it has the same working principle and technical effects as the braking structure in the above embodiments, and will not be described again here.
[0048] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
