Description

Technical Field

[0001] This application relates to the field of riding lawnmower technology, and in particular to a snap-lock mechanism for the grass collection box of a riding lawnmower. Background Technology

[0002] In fields such as gardening maintenance and lawn management, ride-on lawnmowers have become the core equipment for large-area lawn mowing due to their high operating efficiency and wide coverage. As a key component of ride-on lawnmowers, the grass collection box is mainly used to collect weeds generated during the mowing process. During the operation of ride-on lawnmowers, the grass collection box has a large volume, and its weight increases when it is full of grass. It is prone to accidental detachment when encountering bumpy road conditions. Therefore, the stability of its locking mechanism is crucial.

[0003] Existing hay box locking mechanisms in ride-on lawnmowers all employ a spring and hook locking mechanism. Ride-on lawnmowers have large hay boxes, and when full, they are quite heavy. Manually turning the hay box requires overcoming the locking mechanism, which is very strenuous and affects work efficiency. Furthermore, the hook locking method makes the hay box support prone to detachment under significant force, as the force exerted is opposite to the hook's locking force. Therefore, solving these problems is the purpose of this application.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a snap-lock mechanism for the grass collection box of a ride-on lawnmower to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a snap-lock mechanism for the grass collection box of a ride-on lawnmower, comprising: a grass collection box frame, generally U-shaped, with at least one locking plate on the crossbar at the bottom, the locking plate having a locking groove; a locking structure, including a slider, a locking pin, and an elastic component, the slider having an oblique groove, the locking pin being able to slide only along the crossbar and one end of which can be inserted into the locking groove to lock the rotation of the grass collection box frame, the other end being slidably disposed in the oblique groove, the elastic component being able to drive the locking pin to always move towards the locking groove; and a driving structure, which drives the slider to slide longitudinally by manual or electric means to disengage the locking pin from the locking groove.

[0007] In some embodiments, two locking plates are provided and distributed at both ends of the locking structure, and two locking pins and two elastic components are provided and distributed on both sides of the slider. Two oblique grooves are provided on the slider to cooperate with the two locking pins.

[0008] In some embodiments, the locking structure further includes a limiting plate with a limiting groove extending from top to bottom, and a limiting block that can slide in the limiting groove is provided on one side of the slider.

[0009] In some embodiments, the drive structure drives the slider to slide longitudinally via an electric push rod.

[0010] In some embodiments, the drive structure includes a rotating handle, a rotating plate, a fixed base, and a spring cable. The rotating plate is fixedly mounted on the rotating handle, and the rotating handle is rotatably mounted above the fixed base. The rotating plate is connected to the slider via the spring cable, and the rotating handle drives the rotating plate to rotate, thereby causing the spring cable to pull the slider to move longitudinally.

[0011] In some embodiments, a limiting pin is provided on one end of the locking pin near the slider, and the limiting pin can slide within the inclined groove.

[0012] In some embodiments, a locking pin fixing seat is further included, the locking pin fixing seat is fixedly mounted on the grass collection box, the locking pin slides through the locking pin fixing seat, and the elastic member is a spring, sleeved on the outside of the locking pin and located between the two locking pin fixing seats.

[0013] In some embodiments, the locking pin has a stop plate groove, and the locking structure further includes a spring stop plate, which can be inserted into and fixed in the stop plate groove, with one end of the spring abutting against the spring stop plate.

[0014] The beneficial effects of this application are as follows: the locking structure is unlocked by driving the drive structure, and whether an electric push rod or a rotating handle is used, the force required for manual unlocking can be effectively reduced. At the same time, the locking direction of the locking pin is parallel to the crossbar and perpendicular to the unlocking direction of the hay collection box, making it difficult for the hay collection box frame to be locked out due to external factors such as bumps.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0022] In the embodiments of this application, please refer to Figure 1-4 As shown, this application provides a snap-lock mechanism for the grass collection box of a ride-on lawnmower, mainly comprising: a grass collection box frame 1, generally U-shaped, with at least one locking plate 12 on the bottom crossbar 11, the locking plate 12 having a locking groove 121; a locking structure 2, including a slider 21, a locking pin 22, and an elastic component 23, the slider 21 having an oblique groove 211, the locking pin 22 being able to slide only along the crossbar 11 and one end being able to insert into the locking groove 121 to lock the rotation of the grass collection box frame 1, the other end being slidably disposed in the oblique groove 211, the elastic component 23 being able to drive the locking pin 22 to always move in the direction of the locking groove 121; and a driving structure 3, which drives the slider 21 to slide longitudinally by manual or electric means to disengage the locking pin 22 from the locking groove 121.

[0023] Specifically, under normal conditions, the elastic component 23 can drive one end of the locking pin 22 to always be inserted into the locking groove 121. At this time, the crossbar 11 of the grass collection box frame 1 cannot rotate, so that the grass collection box frame 1 is always in a locked state. At the same time, the other end of the locking pin 22 cooperates with the inclined slide groove 211 on the slider 21. When the inclined slide groove 211 slides longitudinally, the relative distance between one end of the locking pin 22 and the axis of the inclined slide groove 211 changes, so that the locking pin 22 can be inserted into or disengaged from the locking groove 121 under the longitudinal movement of the slider 21.

[0024] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0025] Reference Figure 2 As shown, there are two locking plates 12 distributed at both ends of the locking structure 2. There are two locking pins 22 and two elastic components 23 distributed on both sides of the slider 21. The slider 21 has two oblique grooves 211 to cooperate with the two locking pins 22. When the slider 21 moves longitudinally, the two oblique grooves 211 simultaneously drive the two locking pins 22 to move synchronously in opposite directions, so as to simultaneously insert into or disengage from the locking grooves 121 on both sides, thereby improving the stability and reliability of locking.

[0026] Specifically, the locking structure 2 also includes a limiting plate 24, on which a limiting groove 241 is provided from top to bottom. A limiting block 212 that can slide in the limiting groove 241 is provided on one side of the slider 21. Through the cooperation of the limiting block 212 and the limiting groove 241, the slider 21 is restricted to only move in a straight line along the longitudinal direction, so as to prevent the slider 21 from deviating or rotating during the movement, and to ensure that the locking pin 22 can be locked or unlocked accurately.

[0027] In the first embodiment, the drive structure 3 drives the slider 21 to slide longitudinally via an electric push rod 31. The electric push rod 31 is connected to the control system of the lawnmower via a wire. By controlling the longitudinal sliding of the slider 21, the locking pin 22 is driven to lock or unlock, thereby achieving electric locking.

[0028] In the second embodiment, the drive structure 3 includes a rotating handle 32, a rotating plate 33, a fixed base 34, and a spring cable 35. The rotating plate 33 is fixedly mounted on the rotating handle 32, and the rotating handle 32 is rotatably mounted above the fixed base 34. The rotating plate 33 is connected to the slider 21 via the spring cable 35. The rotating handle 32 drives the rotating plate 33 to rotate, causing the spring cable 35 to pull the slider 21 longitudinally. When unlocking is required, the rotating handle 32 is rotated in one direction, causing the rotating plate 33 to rotate, which tightens the spring cable 35 and pulls the slider 21 upward, causing the locking pin 22 to disengage from the locking groove 121. After releasing the rotating handle 32, under the combined action of the elastic component 23 and the spring cable 35, all components reset, achieving manual locking.

[0029] Specifically, a limiting pin 221 is provided on one end of the locking pin 22 near the slider 21. The limiting pin 221 can slide in the inclined slide groove 211. Through the cooperation of the limiting pin 221 and the inclined slide groove 211, the longitudinal movement of the slider 21 is converted into the lateral movement of the locking pin 22.

[0030] Furthermore, it also includes a locking pin fixing seat 22234, which is fixedly mounted on the grass collection box. The locking pin 22 slides through the locking pin fixing seat 22234. The elastic component 23 is a spring, which is sleeved on the outside of the locking pin 22 and located between the two locking pin fixing seats 22234. The locking pin fixing seat 22234 consists of two annular metal sleeves sleeved on the locking pin 22 and fixedly connected to the grass collection box by set screws.

[0031] Specifically, the locking pin 22 has a stop plate groove 223, and the locking structure 2 also includes a spring stop plate 25. The spring stop plate 25 can be inserted into and fixed in the stop plate groove 223. One end of the spring abuts against the spring stop plate 25. The elastic component 23 is a compression spring, which is sleeved on the outside of the locking pin 22. One end of the spring abuts against the spring stop plate 25, and the other end abuts against the locking pin fixing seat 22234. The spring force pushes the locking pin 22 to move towards the locking groove 121.

[0032] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application 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 of the technical features.
