Description

TECHNICAL FIELD

[0001] The utility model relates to a mower return structure technical field, concretely is a throttle pedal return structure of mower. BACKGROUND

[0002] Power tools are generally used to perform manual operations while reducing the amount of manual labor required. For example, a lawn mower can be used to trim grass and weeds. The lawn mower usually uses a high-speed rotating cutting line to trim the grass and weeds;

[0003] The drive of the mower needs to have a neutral position and a forward and reverse switching, which is mainly supported by the following schemes: the throttle pedal is operated to switch the forward-neutral-reverse gears. These gear switching modes are commonly seen on fast-moving vehicles, and the structure is relatively complex. For some slow-moving equipment and vehicles (such as lawn mowers), a more practical gear switching structure is needed, which cannot meet the control requirements, and is suitable for most mechanical structure arrangements. The transmission process does not need to be complicated, but needs to be responsive and timely, meets the use requirements, and achieves the purpose of easy maintenance. Therefore, a throttle pedal return structure of a mower is proposed. SUMMARY

[0004] This section aims to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the utility model name to avoid obscuring the purpose of this section, the abstract of the specification and the utility model name. Such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] Therefore, the purpose of the utility model is to provide a throttle pedal return structure of a mower, which changes the rotation of the hydraulic pump by stepping on the connecting rod transmission and pushing the rotating piece, so as to output the power size, and then automatically returns by the return torsional spring and the pedal return spring. The spring and the connecting rod are linked and matched, which is simple and portable, and the transmission process is simple and responsive.

[0027] This utility model provides a throttle pedal return structure for a lawnmower. Please refer to [link / reference]. Figures 1-4 It includes a base frame 100, a connecting rod assembly 200, and a hydraulic pump return assembly 300;

[0028] Please continue reading. Figures 1-4 The base frame 100 serves as a connecting base frame, and a bracket 110 is connected to the top of the base frame 100;

[0029] The bracket 110 is provided with a connecting seat 111, the other end of the connecting seat 111 is connected to the return spring 120, and the other end of the return spring 120 is connected to the connecting frame 210.

[0030] action:

[0031] When the pedal is pressed (forward pedal 211 or backward pedal 212), since the connecting frame 210 is connected to the bracket 110 through the return spring 120, when the pedal is pressed, the return spring 120 will deform, converting kinetic energy into elastic potential energy for storage. After the pedal is released, the return spring 120 returns to its circular shape, converting elastic potential energy into kinetic energy and driving the pedal to return to its original position.

[0032] Please continue reading. Figures 1-4 The linkage component 200 is provided in two sets, and the two sets of linkage components 200 are symmetrically connected to the base frame 100. The linkage component 200 serves as the power transmission intermediate, transmitting the action made by the pedal to the hydraulic pump return component 300.

[0033] The linkage component 200 includes a connecting frame 210 rotatably connected to the outside of the base frame 100, and a connecting rod 220 connected to the connecting frame 210 and movable on the base frame 100. A forward pedal 211 is connected to the top of the connecting frame 210, and a reverse pedal 212 is provided on the outside of the connecting frame 210. Anti-slip protrusions (not shown in the figure) are provided on the outside of both the forward pedal 211 and the reverse pedal 212.

[0034] A connecting seat 221 is connected to the center of the connecting rod 220. A connecting plate 222 is hinged to the bottom of the connecting seat 221. The bottom of the connecting plate 222 is bent. The bottom of the connecting plate 222 is hinged to the linkage plate 230. The linkage plate 230 is connected to the base frame 100. The other end of the linkage plate 230 is connected to the connecting rod 231 and drives the connecting rod 231 to move synchronously.

[0035] action:

[0036] When the connecting rod 220 follows the pedal movement, it drives the connecting seat 221 and the connecting plate 222 to move synchronously, so that the linkage plate 230 and the connecting rod 231 move back and forth, and transmit power to the hydraulic pump return component 300.

[0037] Please continue reading. Figure 2 The hydraulic pump return component 300 is connected to the end of the connecting rod component 200 and moves synchronously with the connecting rod component 200.

[0038] The hydraulic pump return component 300 includes a rotating plate 310 hinged to the end of the connecting rod 231, and a transmission component 320 connected to the rotating plate 310. The rotating plate 310 and the transmission component 320 are rotatably coupled. The transmission component 320 is provided with two sets of linkage plates 321. The two sets of linkage plates 321 are connected by a return torsion spring 330. The two sets of linkage plates 321 follow the movement of the rotating plate 310.

[0039] action:

[0040] When the connecting rod 231 moves back and forth, it drives the rotating plate 310 to swing back and forth, which in turn causes the linkage plate 321 to follow the movement of the rotating plate 310 (when the rotating plate swings forward, it drives the linkage plate on the front side to move, and vice versa, it drives the linkage plate on the rear side to move), thus controlling the output power of the hydraulic pump.

[0041] Working principle: When using this utility model, stepping on the pedal (forward pedal 211 or backward pedal 212) causes the pedal to drive the connecting rod 220. As the connecting rod 220 follows the pedal's movement, it drives the connecting seat 221 and the connecting plate 222 to move synchronously, causing the linkage plate 230 and the connecting rod 231 to move back and forth, transmitting power to the hydraulic pump return component 300. When the connecting rod 231 moves back and forth, it drives the rotating plate 310 to swing back and forth, thereby causing the linkage plate 321 to move with the rotating plate 310, thus controlling the output power of the hydraulic pump. It is simple and portable to operate by foot pedal, and the transmission process is simple and timely.

[0042] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
