Technical Field

[0001] The utility model relates to the technical field of lawn mowers, in particular to a riding lawn mower. Background Art

[0002] As a garden tool, lawn mowers are widely used in the field of mowing lawns and other vegetation.

[0003] Existing lawn mowers generally include handheld lawn mowers and riding lawn mowers. Among them, handheld lawn mowers are widely used due to their small size and convenient portability. However, the mowing capacity, mowing efficiency, and battery life of handheld lawn mowers cannot meet the needs of large lawns. Therefore, a riding lawn mower has gradually appeared on the market.

[0004] The prior art WO2019129045A1 discloses a riding electric lawn mower, comprising a seat for a user to sit on; a main frame for carrying the seat; a power output assembly, comprising a mowing element for outputting power to achieve a mowing function and a first motor for driving the mowing element to output the power; a walking assembly, which can at least drive the rideable electric lawn mower to walk along a first straight direction on the ground, and a second motor for driving the walking assembly; and a power supply device, comprising a first battery pack for supplying energy to the rideable electric lawn mower, the first battery pack comprising a first battery pack housing and a battery cell, and being arranged inside the first battery pack housing, the power supply device is mounted on the main frame, at least one first battery pack in the power supply device forms a pluggable connection with the main frame, and the battery cell is a lithium battery.

[0005] In the above-mentioned riding electric lawn mower, since the power supply device is directly fixed on the main frame, and the lawn mower copes with various complex terrain conditions during the mowing process, such as uphill, downhill, flat and irregular ground, the power supply device of the riding lawn mower will be subject to greater bumps when mowing, which may easily cause damage to the power supply device, thereby affecting the service life of the power supply device. Utility Model Content

[0006] The purpose to be achieved by the utility model is to provide a riding lawn mower, which solves the problem that the power supply device is subjected to large bumps and is easily damaged, reduces the possibility of damage to the power supply device due to bumps, and further reduces the impact of vibration on the service life of the power supply device.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a riding lawn mower, comprising a main frame, a seat, a power supply device and a wheel assembly arranged on the main frame, the main frame is provided with a seat bracket, the seat bracket is connected to the main frame through a shock absorbing device, and the power supply device and the seat are arranged on the seat bracket.

[0008] After adopting the above technical scheme, the utility model has the following advantages: when assembling the lawn mower, a seat bracket is installed on the main frame of the lawn mower, the seat is installed on the seat bracket, and then a shock absorbing device is installed between the seat bracket and the main bracket, and finally the energy supply device is installed on the seat bracket. When the lawn mower is mowing on the grass, the energy supply device provides power to the wheel assembly to make the lawn mower move forward, backward or turn. When the lawn mower runs on uneven ground, the shock absorbing device reduces the shock of the operator riding on the seat, reducing the possibility of the operator falling from the seat. At the same time, the shock absorbing assembly reduces the shock of the energy supply device installed on the seat bracket, reducing the possibility of the energy supply device vibrating with the main frame with a large amplitude, and further reducing the impact of vibration on the service life of the power supply device.

[0009] Furthermore, the seat and the energy supply device are distributed front and back along the moving direction of the lawn mower.

[0010] By adopting the above-mentioned technical solution, by installing the energy supply device behind the seat, the space in front of the seat is relatively large, which is convenient for the operator to operate the lawn mower on the seat.

[0011] Furthermore, the seat bracket is arranged around the outside of the energy supply device.

[0012] By adopting the above-mentioned technical solution, the energy supply device is enclosed by the seat bracket, thereby improving the installation stability of the energy supply device on the seat bracket and reducing the possibility of the energy supply device detaching from the seat bracket.

[0013] Furthermore, the shock absorbing device is arranged between the rear end of the seat support and the main frame, and the front end of the seat support is hinged to the main frame; or, the shock absorbing device is arranged between the front end of the seat support and the main frame, and the rear end of the seat support is hinged to the main frame.

[0014] By adopting the above-mentioned technical solution, the front end of the seat support is hinged to the main frame, and the shock absorbing device is connected to the rear end of the seat support and the main frame; or, the shock absorbing device is connected between the front end of the seat support and the main frame, and the front end of the seat support and the main frame are hinged, so that the energy supply device can obtain a better buffering effect in the shock absorbing device without affecting the stability of the seat support, thereby reducing the possibility of affecting the service life of the energy supply device due to vibration.

[0015] Furthermore, the shock absorbing device includes a buffer sleeve and a buffer rod, one end of the buffer sleeve is hinged to the main frame, and the other end extends toward the seat bracket, one end of the buffer rod is hinged to the seat bracket, and the other end extends toward the buffer sleeve and is inserted into the buffer sleeve, and when the seat bracket and the energy supply device buffer, the buffer rod is reciprocated in the buffer sleeve to reduce shock.

[0016] By adopting the above-mentioned technical solution, when the main frame vibrates, the seat bracket vibrates along with the main frame, and the buffer rod is reciprocated in the buffer sleeve to reduce the vibration amplitude of the seat bracket. As the seat bracket vibrates, the buffer sleeve and the hinge of the buffer rod also rotate along with the insertion of the buffer rod and the buffer sleeve, further reducing the vibration amplitude of the seat bracket and the vibration of the seat bracket, thereby reducing the possibility of the service life of the energy supply device being affected by vibration.

[0017] Furthermore, the shock absorbing device includes a shock absorbing elastic member, one end of which is arranged on the main frame and the other end is arranged on the seat support, and the shock absorbing elastic member expands and contracts during the shock absorbing process.

[0018] By adopting the above-mentioned technical solution, a shock-absorbing elastic part is installed between the main frame and the seat bracket. When the main frame vibrates and drives the seat bracket to vibrate along with the main frame, the shock-absorbing elastic part expands and contracts between the main frame and the seat bracket, thereby reducing the amplitude of the seat bracket vibrating along with the main frame, thereby reducing the impact of the seat bracket vibration on the service life of the energy supply device.

[0019] Furthermore, the wheel assembly includes a driving rear wheel and an auxiliary front wheel, and the center of gravity of the energy supply device is arranged on the rear side of the driving rear wheel.

[0020] By adopting the above-mentioned technical solution, the energy supply device is located on the rear side of the driving rear wheel, so that the center of gravity of the energy supply device acts on the driving rear wheel as much as possible, reducing the possibility of the auxiliary front wheel being affected by the greater gravity it bears.

[0021] Furthermore, the seat bracket is provided with a supporting member for supporting the energy supply device, and the energy supply device is detachably arranged between the seat bracket and the supporting member.

[0022] By adopting the above-mentioned technical solution, the energy supply device can be detachably installed on the seat bracket through the seat bracket and the support member, which facilitates the installation of the energy supply device and reduces the difficulty of replacing the energy supply device.

[0023] Furthermore, an installation groove is provided on the outer wall of the energy supply device, and the installation groove is plugged into the seat bracket. The energy supply device and the seat bracket are detachably arranged via a fixing piece.

[0024] By adopting the above-mentioned technical solution, when the energy supply device is installed on the seat bracket, the installation groove on the outer wall of the energy supply device is plugged into the seat bracket, and then the energy supply device and the seat bracket are detachably installed through the fixing parts. By plugging the installation groove into the seat bracket, the possibility of the energy supply device being separated from the seat bracket when the seat bracket vibrates is reduced, thereby reducing the possibility of the energy supply device being separated from the seat bracket and damaged during vibration.

[0025] Furthermore, the energy supply device is provided with an elastic connector, one end of the elastic connector away from the energy supply device is detachably arranged on the seat bracket, and one end of the energy supply device away from the elastic connector is detachably arranged on the seat bracket.

[0026] By adopting the above-mentioned technical solution, one end of the energy supply device can be detachably mounted on the seat bracket, and the other end can be detachably arranged with the seat bracket through an elastic connecting piece. When the seat bracket vibrates on the main frame, the elastic connecting piece reduces the vibration amplitude of the energy supply device following the seat bracket, thereby reducing the possibility of the service life of the energy supply device being affected by vibration.

[0037] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0038] like Figure 1 and Figure 2 As shown, the utility model provides a riding lawn mower, including a main frame 1, a seat 2, an energy supply device 3 and a wheel assembly 4 arranged on the main frame 1, the energy supply device 3 is electrically connected to a driving member in the wheel assembly 4, so that the energy supply device 3 provides power for the operation of the wheel assembly 4, and when the wheel assembly 4 is running, it drives the lawn mower to move on the grass.

[0039] In this embodiment, in order to reduce the possibility that the service life of the energy supply device 3 is affected by the vibration of the main frame 1, a seat bracket 5 is provided on the main frame 1, and the seat 2 and the energy supply device 3 are both arranged on the seat bracket 5. One end of the seat bracket 5 is hinged to the main frame 1, and the other end is connected to the main frame 1 through a shock absorbing device 6.

[0040] In this embodiment, if Figures 1 to 3As shown, the front end of the seat bracket 5 distributed along the running direction of the main frame 1 is hinged to the main frame 1. Specifically, a mounting seat 11 is provided on the main frame 1, and a rotating rod 12 is detachably fixed on the mounting seat 11. The seat bracket 5 is rotatably connected to the rotating rod 12. When the shock absorbing device 6 buffers the seat bracket 5, the front end of the seat bracket 5 and the rotating rod 12 rotate due to the vibration amplitude of the seat bracket 5, and the rear end of the seat bracket 5 is appropriately rotated upward relative to the front end. The front end of the seat bracket 5 is hinged and the rear end is connected to the main frame 1 through the shock absorbing device 6, which further reduces the possibility of the seat bracket 5 producing a large amplitude with the vibration of the main frame 1, thereby reducing the possibility of the energy supply device 3 being affected by the vibration. The service life.

[0041] In this embodiment, if Figure 2 and Figure 4 As shown, specifically, the shock absorbing device 6 includes a buffer sleeve 61 and a buffer rod 62, one end of the buffer sleeve 61 is hinged on the main frame 1, and the other end extends toward the seat bracket 5, one end of the buffer rod 62 is hinged on the seat bracket 5, and the other end extends toward the buffer sleeve 61 and is inserted in the buffer sleeve 61, when the main frame 1 and the seat bracket 5 have relative movement due to vibration, the buffer rod 62 is reciprocated in the buffer sleeve 61 to reduce shock, and the principle of shock reduction by the reciprocating connection of the buffer rod 62 and the buffer sleeve 61 is consistent with the operating principle of the existing hydraulic damper, through the reciprocating connection between the buffer rod 62 and the buffer sleeve 61, the vibration of the seat bracket 5 and the energy supply device 3 installed on the seat bracket 5 caused by the vibration of the main frame 1 is reduced, and the service life of the energy supply device 3 affected by the large vibration amplitude of the energy supply device 3 is further reduced.

[0042] In another embodiment, if Figure 2 and Figure 5 As shown, the shock absorbing device 6 includes a shock absorbing elastic member 63. Specifically, the shock absorbing elastic member 63 includes a shock absorbing spring, one end of which is arranged on the main frame 1, and the other end is arranged at the rear end of the seat bracket 5. When the seat bracket 5 and the main frame 1 move relative to each other due to vibration, the shock absorbing spring expands and contracts between the main frame 1 and the seat bracket 5, further reducing the vibration amplitude of the seat bracket 5 on the main frame 1, thereby reducing the possibility that the seat bracket 5 drives the energy supply device 3 to vibrate with a large amplitude and affects the service life of the energy supply device 3.

[0043] In another embodiment, if Figure 5 As shown, the shock-absorbing spring is sleeved between the buffer sleeve 61 and the buffer rod 62. During shock absorption, the buffer sleeve 61 and the buffer rod 62 are reciprocated and inserted, while the shock-absorbing spring expands and contracts, further reducing the possibility that the service life of the energy supply device 3 is affected by a large vibration amplitude.

[0044] In another embodiment, the rear end of the seat bracket 5 along the running direction of the main frame 1 is hinged to the main frame 1, and the front end of the seat bracket 5 is connected through a shock absorbing device 6. The shock absorbing device 6 and the energy supply device 3 are distributed at both ends of the seat bracket 5. When the shock absorbing device 6 is shock absorbing and buffering, the energy supply device 3 generates a smaller vibration amplitude due to being away from the shock absorbing device 6, thereby reducing the possibility that the seat bracket 5 will affect the service life of the energy supply device 3 due to the large amplitude of vibration of the main frame 1.

[0045] In another embodiment, if Figure 1 As shown, the seat 2 and the energy supply device 3 are distributed front and back along the movement direction of the lawn mower. The seat 2 is installed in front of the energy supply device 3, so that the space in front of the seat 2 is relatively large, which is convenient for the operator to operate the lawn mower on the seat 2.

The driving rear wheel 41 and the auxiliary front wheel 42 are both rotatably mounted on the main frame 1. The auxiliary front wheel 42 is used to assist the lawn mower in steering. The energy supply device 3 is located on the rear side of the driving rear wheel 41 to reduce the possibility that the weight of the energy supply device 3 acts on the auxiliary front wheel 42 and increases the difficulty of steering the lawn mower.

[0047] In another embodiment, the seat bracket 5 is arranged along the outer side of the energy supply device 3 to improve the installation stability of the energy supply device 3 on the seat bracket 5 and reduce the possibility of relative displacement between the energy supply device 3 and the seat bracket 5 during the operation of the lawn mower.

[0048] In another embodiment, if Figure 6 As shown, in order to facilitate the installation of the energy supply device 3, a support member 51 is provided on the seat bracket 5. Specifically, the support member 51 includes a support plate. The energy supply device 3 is installed between the support plate and the seat bracket 5. The energy supply device 3 and the support plate are detachably installed. The energy supply device 3 and the seat bracket 5 are detachably installed. This facilitates the installation of the energy supply device 3 and facilitates the disassembly and replacement of the energy supply device 3 through the detachable installation.

[0049] In another embodiment, if Figure 7 As shown, a mounting groove 31 is provided on the outer wall of the energy supply device 3, and the seat bracket 5 and the mounting groove 31 are plugged into each other. The front and rear ends of the energy supply device 3 are detachably mounted on the seat bracket 5 through fixing parts. Specifically, the fixing parts include fixing bolts and fixing nuts. The fixing bolts pass through the energy supply device 3 and are threadedly connected to the seat bracket 5. The fixing nuts are threadedly connected to the end of the fixing bolts away from the energy supply device 3, thereby detachably mounting the energy supply device 3 on the seat bracket 5. By plugging the mounting groove 31 into the seat bracket 5, the possibility of the energy supply device 3 being separated from the seat bracket 5 due to a small vibration of the seat bracket 5 is reduced, thereby improving the stability of the installation of the energy supply device 3.

[0050] In another embodiment, Figure 7 As shown, an elastic connector 32 is installed on the front end of the energy supply device 3. Specifically, the elastic connector 32 includes an elastic connecting plate. One end of the elastic connecting plate is arranged at one end of the energy supply device 3. The end of the elastic connecting plate away from the energy supply device 3 is detachably installed with the seat bracket 5 by bolts. The elastic connecting plate reduces the possibility that the energy supply device 3 vibrates when the vibration amplitude of the seat bracket 5 is large, thereby affecting the service life of the energy supply device 3.
