Description

Technical Field

[0001] This utility model relates to the field of garden tools technology, specifically to a garden operation vehicle and a ride-on lawnmower. Background Technology

[0002] Gardening vehicles generally refer to vehicles used for outdoor gardening operations, mainly including vehicles used for tasks such as cutting and maintenance of gardens.

[0003] Lithium-ion battery lawnmowers are widely used as lawn machinery for mowing lawns and other vegetation. Due to battery life limitations, lithium-ion battery lawnmowers require frequent battery pack replacements, making opening the battery compartment cover an essential operation.

[0004] In existing technology, a battery compartment is located at the rear of the frame of a lithium-ion battery mower (behind the seat). The battery pack is installed in the battery compartment, and the front end of the battery compartment cover is hinged to the front end of the battery compartment via a rotating shaft. When replacing the battery pack, the user needs to manually flip the battery compartment cover upwards to open the battery compartment, and after replacing the battery pack, the user needs to manually flip the battery compartment cover downwards again to close the battery compartment. In actual production, the above structure has the following shortcomings:

[0005] (1): The battery compartment cover has no support and no position. When the battery compartment cover is opened, it is easy for the battery compartment cover to collide with the seat. Over time, the battery compartment cover and the seat will be worn, which will not only affect the appearance, but also affect the service life of the battery compartment cover and the seat. After the battery compartment cover is closed, during the vehicle driving, the vehicle bumps will cause the battery compartment cover to open and close frequently and collide with the battery compartment cover.

[0006] (2): The battery compartment cover needs to be opened manually. In order to keep the battery compartment cover open when taking out or putting in the battery pack, a supporting force needs to be applied to the battery compartment cover at all times. When the battery pack is heavy, it is difficult for users to support the battery compartment cover with one hand and take out or put in the battery pack with the other hand, which can easily lead to a poor user experience.

[0060] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.

[0061] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0062] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0063] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0064] Examples, such as Figure 1-13 As shown, a gardening operation vehicle includes: a frame 10, a driving component 30, an operation component 40, and a power supply system 50; the frame 10 extends in a front-to-back direction; the driving component 30 is mounted on the frame 10 for driving the vehicle to move; the operation component 40 is mounted on the frame 10 for performing gardening operations; the power supply system 50 is mounted on the frame 10 and electrically connected to the driving component 30 for providing power for vehicle movement, and the power supply system 50 is electrically connected to the operation component 40 for providing power for gardening operations.

[0065] The power supply system 50 includes a battery compartment body 51, a battery compartment cover 52, a battery pack, and a booster 53. The battery compartment body 51 is mounted on the vehicle frame 10, and the battery pack is placed in the battery compartment of the battery compartment body 51. The battery compartment cover 52 is hinged to the battery compartment body 51. One end of the booster 53 is hinged to the battery compartment body 51, and the other end of the booster 53 is hinged to the battery compartment cover 52. The battery compartment cover 52 has an upper cover position that flips up to facilitate the user to put in and take out the battery pack, a lower cover position that closes down to close the battery compartment, and a transition cover position located between the upper cover position and the lower cover position.

[0066] When the battery compartment cover 52 is located between the upper cover position and the transition cover position, the assist member 53 can apply a force to the battery compartment cover 52 to move the battery compartment cover 52 toward the upper cover position. When the battery compartment cover 52 is located between the lower cover position and the transition cover position, the assist member 53 can apply a force to the battery compartment cover 52 to move the battery compartment cover 52 toward the lower cover position.

[0067] This invention incorporates an assistive component 53 between the battery compartment body 51 and the battery compartment cover 52 of a garden vehicle. The external force applied to the upward-flipping battery compartment cover 52 by the extension and retraction of the assistive component 53 not only enables semi-automatic opening of the battery compartment cover 52 but also provides support and limitation after opening. Simultaneously, the external force applied to the downward-closing battery compartment cover 52 by the extension and retraction of the assistive component 53 creates a pre-tightening force between the battery compartment cover 52 and the battery compartment body 51, thus forming a unified structure. This improves the stability of the battery compartment cover 52 and battery compartment body 51 when closed, preventing collisions between them caused by vehicle bumps and thereby extending the equipment's service life.

[0068] like Figure 1 As shown, in one specific embodiment, a gardening vehicle includes a frame 10, a working component 40, and a power supply system 50; the frame 10 extends in a front-rear direction, the working component 40 is configured as a cutter for performing grass mowing operations, the cutter is mounted on the frame 10; the power supply system 50 is installed at the rear of the frame 10 and is electrically connected to the cutter to provide power for grass mowing operations.

[0069] like Figure 2 , Figure 3 and Figure 4 As shown, in some optional embodiments, the power supply system 50 includes a battery compartment body 51, a battery compartment cover 52, a battery pack (not shown in the figure), and a booster 53. The battery compartment body 51 is fixedly installed above the rear of the vehicle frame 10, that is, the bottom of the battery compartment body 51 is fixedly connected to the rear of the vehicle frame 10, and the battery pack is placed in the battery compartment of the battery compartment body 51. The battery compartment cover 52 is hinged to the battery compartment body 51, and the booster 53 is installed between the battery compartment body 51 and the battery compartment cover 52, that is, one end of the booster 53 is hinged to the battery compartment body 51, and the other end of the booster 53 is hinged to the battery compartment cover 52.

[0070] like Figure 3 and Figure 7 As shown, the battery compartment cover 52 has an upper cover position that flips upward to facilitate the user's access to and from the battery pack. When the battery compartment cover 52 is in the upper cover position, that is, when the battery compartment cover 52 is flipped upward to the limit position, the battery compartment cover 52 is in a fully open state, and the battery compartment is fully exposed, which makes it easy for the user to take the battery pack out of the battery compartment and also easy for the user to put the battery pack back into the battery compartment.

[0071] like Figure 4 and Figure 7As shown, the battery compartment cover 52 has a lower cover position that closes downward to close the battery compartment. When the battery compartment cover 52 is in the lower cover position, that is, when the battery compartment cover 52 is closed downward to the limit position, the battery compartment cover 52 is in a fully closed state, and the battery compartment is completely sealed, thereby fixing the battery pack inside the battery compartment and realizing the fixation and protection of the battery pack.

[0072] like Figure 7 As shown, the battery compartment cover 52 has a transition cover position located between the upper cover position and the lower cover position. When the battery compartment cover 52 is located between the upper cover position and the transition cover position, the assisting member 53 can apply a force to the battery compartment cover 52 to move it towards the upper cover position. During the upward flipping process, after the battery compartment cover 52 passes the transition cover position, it can automatically move to the upper cover position under the external force of the assisting member 53, thus achieving semi-automatic opening of the battery compartment cover 52. When the battery compartment cover 52 is located between the lower cover position and the transition cover position, the assisting member 53 can apply a force to the battery compartment cover 52 to move it towards the lower cover position. During the downward closing process, after the battery compartment cover 52 passes the transition cover position, it can automatically move to the lower cover position under the external force of the assisting member 53, thus achieving semi-automatic closing of the battery compartment cover 52.

[0073] like Figure 3 and Figure 4 As shown, in some optional embodiments, the power supply system 50 includes a battery compartment body 51, a battery compartment cover 52, a battery pack, and a booster component 53. The battery compartment body 51 is fixedly installed above the rear of the vehicle frame 10 and has a battery compartment with a top opening. Multiple battery packs are detachably installed in the battery compartment. The front end of the battery compartment cover 52 is hinged to the front end of the battery compartment body 51 via a rotating shaft 56, so that the battery compartment cover 52 can be flipped upward and downward around the rotating shaft 56.

[0074] The assistive component 53 is installed between the battery compartment body 51 and the battery compartment cover 52. An upper hinge seat 54 is installed on the battery compartment cover 52. One end of the assistive component 53 is connected to the upper hinge seat 54, that is, the movement center point 3 of the assistive component 53 is connected to the upper hinge seat 54. A mounting slope is provided near the front end of the battery compartment body 51. The mounting slope is located directly below the upper end surface of the battery compartment body 51, and the height of the front end of the mounting slope is higher than the height of the rear end of the mounting slope. A lower hinge seat 55 is installed on the mounting slope. The other end of the assistive component 53 is connected to the lower hinge seat 55, that is, the hinge center point 2 of the assistive component 53 is connected to the lower hinge seat 55.

[0075] like Figure 4 and Figure 7 As shown, in some optional embodiments, the hinge point between the battery compartment cover 52 and the battery compartment body 51 is lower than the hinge point between the assist member 53 and the battery compartment body 51. That is, in the vertical direction, the height of the hinge point between the assist member 53 and the battery compartment body 51 is higher than the height of the hinge point between the battery compartment cover 52 and the battery compartment body 51. In other words, the height of the hinge center point 2 of the assist member 53 is higher than the height of the rotation center point 1 of the battery compartment cover 52.

[0076] like Figure 7 As shown, further, when the battery compartment cover 52 is in the transition cover position, the hinge point between the battery compartment cover 52 and the battery compartment body 51 is approximately located on the axial extension line of the assist member 53. This allows the battery compartment cover 52 to move towards the upper cover position when it is between the upper cover position and the transition cover position, and the force applied to the battery compartment cover 52 by the assist member 53 during extension and retraction can move the battery compartment cover 52 towards the lower cover position when it is between the lower cover position and the transition cover position.

[0077] like Figure 7 As shown, in some optional embodiments, when the angle between the assisting member 53 and the horizontal plane is 13°, that is, when the angle between the axis of the assisting member 53 and the horizontal direction is 13°, the upper hinge point (top hinge point), the lower hinge point (bottom hinge point), the hinge point of the battery compartment cover 52 and the battery compartment body 51 are collinear, that is, the rotation center point 1 of the battery compartment cover 52, the hinge center point 2 of the assisting member 53 and the motion center point 3 of the assisting member are collinear. When the battery compartment cover 52 continues to flip upward in this state, the elastic force of the assisting member 53 acts on the battery compartment cover 52, causing the top of the battery compartment cover 52 to continue to flip upward around the bottom, thereby enabling the assisting member 53 to assist the battery compartment cover 52 to bounce upward. Conversely, when the battery compartment cover 52 descends in this state, the elastic force of the assisting member 53 acts on the battery compartment cover 52, causing the top of the battery compartment cover 52 to continue to flip downward around the bottom, thereby enabling the assisting member 53 to assist in closing the battery compartment cover 52 downward.

[0078] like Figure 7 and Figure 9 As shown, in some optional embodiments, the angle between the upper cover position and the lower cover position is 65° to 75°, that is, the angle between the battery compartment cover 52 at the upper cover position and the battery compartment cover 52 at the lower cover position is 65° to 75°.

[0079] like Figure 7 and Figure 11As shown, in some optional embodiments, the angle between the lower cover position and the transition cover position is 8° to 18°, that is, the angle between the battery compartment cover 52 at the lower cover position and the battery compartment cover 52 at the transition cover position is 8° to 18°.

[0080] In some optional embodiments, the angle between the upper cover position and the lower cover position is 65°; the angle between the transition cover position and the lower cover position is 8°.

[0081] In some optional embodiments, the angle between the upper cover position and the lower cover position is 70°; the angle between the transition cover position and the lower cover position is 13°.

[0082] In some optional embodiments, the angle between the upper cover position and the lower cover position is 75°; the angle between the transition cover position and the lower cover position is 19°.

[0083] like Figure 1 As shown in one specific embodiment, a gardening operation vehicle includes a frame 10, a seat 20, an operation component 40, and a power supply system 50. The frame 10 extends in a front-to-back direction, the seat 20 is mounted on the frame 10 and used to carry a user, the operation component 40 is mounted on the frame 10 and used to perform gardening operations, and the power supply system 50 is mounted on the frame 10 and electrically connected to the operation component 40 to provide power for gardening operations.

[0084] like Figure 2 , Figure 3 and Figure 4 As shown, in some optional embodiments, the power supply system 50 includes a battery compartment 51, a battery compartment cover 52, a battery pack, and a booster component 53. The battery compartment 51 is fixedly installed above the rear of the vehicle frame 10, and the battery pack is placed in the battery compartment of the battery compartment 51. The battery compartment cover 52 is hinged to the battery compartment 51.

[0085] like Figure 3 and Figure 7 As shown, the battery compartment cover 52 has an upper cover position that flips upward to facilitate the user's access to and from the battery pack. When the battery compartment cover 52 is in the upper cover position, that is, when the battery compartment cover 52 is flipped upward to the limit position, the battery compartment cover 52 is in a fully open state, exposing the inside of the battery compartment, which makes it easy for the user to take the battery pack out of the battery compartment and also easy for the user to put the battery pack back into the battery compartment.

[0086] like Figure 4 and Figure 7As shown, the battery compartment cover 52 has a lower cover position that closes downward to close the battery compartment. When the battery compartment cover 52 is in the lower cover position, that is, when the battery compartment cover 52 is closed downward to the limit position, the battery compartment cover 52 is in a fully closed state, and the battery compartment is completely sealed, thereby fixing the battery pack inside the battery compartment and realizing the fixation and protection of the battery pack.

[0087] like Figure 7 As shown, the battery compartment cover 52 has a transition cover position located between the upper cover position and the lower cover position. When the battery compartment cover 52 is located between the upper cover position and the transition cover position, the assisting member 53 can apply a force to the battery compartment cover 52 to move it towards the upper cover position. During the upward flipping process, after the battery compartment cover 52 passes the transition cover position, it can automatically move to the upper cover position under the external force of the assisting member 53, thus achieving semi-automatic opening of the battery compartment cover 52. When the battery compartment cover 52 is located between the lower cover position and the transition cover position, the assisting member 53 can apply a force to the battery compartment cover 52 to move it towards the lower cover position. During the downward closing process, after the battery compartment cover 52 passes the transition cover position, it can automatically move to the lower cover position under the external force of the assisting member 53, thus achieving semi-automatic closing of the battery compartment cover 52.

[0088] The number of the assistive component 53 is multiple, meaning that the number of assistive components 53 is at least two.

[0089] like Figure 2 As shown, in some optional embodiments, there are two assistive components 53. When there are two assistive components 53, the two assistive components 53 are arranged on the left and right sides of the battery compartment body 51, one on the left and one on the right, in the width direction of the battery compartment cover 52, that is, in the left and right direction. Lower hinge seats 55 are installed on the left and right sides of the top of the battery compartment body 51, and upper hinge seats 54 are fixedly installed on the left and right sides of the battery compartment cover 52. The top end of the assistive component 53 is connected to the upper hinge seat 54, and the bottom end of the assistive component 53 is connected to the lower hinge seat 55.

[0090] like Figure 6 As shown, in some optional specific embodiments, the width dimension of the battery compartment cover 52 in the left-right direction is W1, that is, the maximum width of the battery compartment cover 52 is W1, the distance between two adjacent assisting members 53 is W2, that is, the installation distance width of the two gas springs is W2, and 0.4 < W2 / W1 < 1.

[0091] In some embodiments, the battery compartment cover 52 is a wide and flat plastic part that undergoes a certain degree of plastic deformation during rotation. Two auxiliary components 53 are symmetrically installed on the left and right sides of the battery compartment cover 52, with 0.4 < W2 / W1 < 1. This allows the auxiliary components 53 to better control the battery compartment cover 52, preventing large plastic deformation and avoiding poor user experience caused by long-term plastic deformation, such as component aging and vibration.

[0092] In some optional embodiments, W1 = 680 mm, W2 = 574 mm, and W2 / W1 = 0.844.

[0093] In some optional embodiments, W1 = 650 mm, W2 = 404 mm, and W2 / W1 = 0.622.

[0094] In some optional embodiments, W1 = 590 mm, W2 = 565 mm, and W2 / W1 = 0.958.

[0095] In some optional embodiments, when the number of assistive components 53 is three, the three assistive components 53 are arranged in parallel, and the three assistive components 53 are spaced apart in the width direction of the battery compartment cover 52, that is, in the left and right direction. That is, two of the assistive components 53 are arranged on the left and right sides of the battery compartment body 51, and the remaining assistive component 53 is installed in the middle of the battery compartment body 51 (the middle of the battery compartment body 51 is provided with a mounting rib). This makes the multiple assistive components 53 symmetrically arranged between the battery compartment body 51 and the battery compartment cover 52 in the width direction of the battery compartment body 51.

[0096] Lower hinge seats 55 are installed on the left and right sides of the top of the battery compartment 51, and upper hinge seats 54 are fixedly installed on the left and right sides of the battery compartment cover 52. The top end of the assisting component 53 is connected to the upper hinge seat 54, and the bottom end of the assisting component 53 is connected to the lower hinge seat 55.

[0097] In some optional embodiments, W1 = 710 mm, W2 = 336 mm, and W2 / W1 = 0.473.

[0098] like Figure 1 and Figure 3As shown, in some optional embodiments, the hinge point between the battery compartment cover 52 and the battery compartment body 51 is located between the hinge point between the assist member 53 and the battery compartment body 51 and the seat 20. That is, in the extension direction (front and rear direction) of the frame 10, the hinge point between the battery compartment cover 52 and the battery compartment body 51 is closer to the seat 20 than the hinge point between the assist member 53 and the battery compartment body 51. This allows the battery compartment cover 52 to flip forward when opened, that is, when the battery compartment cover 52 is opened, the battery compartment cover 52 moves toward the seat 20, thereby facilitating the user to take out and put in the battery pack, and avoiding interference of the battery compartment cover 52 with the movement path of the battery pack.

[0099] like Figure 1 As shown, in one specific embodiment, a gardening operation vehicle includes a frame 10, an operation component 40, and a power supply system 50; the frame 10 extends in a front-to-back direction, the operation component 40 is mounted on the frame 10 for performing gardening operations; the power supply system 50 is mounted on the frame 10 and is electrically connected to the operation component 40 for providing power for gardening operations.

[0100] like Figure 2 , Figure 3 and Figure 4 As shown, in some optional embodiments, the power supply system 50 includes a battery compartment body 51, a battery compartment cover 52, a battery pack, and a booster component 53. The battery compartment body 51 is fixedly installed above the rear of the vehicle frame 10, that is, the bottom of the battery compartment body 51 is fixedly connected to the rear of the vehicle frame 10, and the battery compartment body 51 has a battery compartment with a top opening, and the battery pack is placed in the battery compartment of the battery compartment body 51. The front end of the battery compartment cover 52 is hinged to the front end of the battery compartment body 51 through a rotating shaft 56. The booster component 53 is a gas spring or a gas strut. The gas spring is installed between the battery compartment body 51 and the battery compartment cover 52, that is, the top end of the gas spring is hinged to the battery compartment body 51, and the bottom end of the gas spring is hinged to the battery compartment cover 52.

[0101] like Figure 8As shown, in some optional embodiments, the gas spring consists of a sleeve 531, a piston rod 532, a sealing guide sleeve, filler, a pressure cylinder, and a connector. The pressure cylinder is a sealed cavity filled with inert gas or an oil-gas mixture, and the pressure inside the cavity is several times or tens of times atmospheric pressure. The sleeve 531 is fixedly sleeved on the outside of the pressure cylinder. The piston rod 532 and the sleeve 531 are coaxially arranged. The top end of the piston rod 532 is slidably connected to the inside of the sleeve 531, and the top end of the piston rod 532 is slidably connected to the pressure cylinder via a piston. The bottom end of the piston rod 532 is hinged to the battery compartment 51, and the top end of the sleeve 531 is hinged to the battery compartment cover 52. The piston rod 532 and the gas spring 31 are positioned one above the other. The piston rod 532 is located inside the sleeve 531 and can reciprocate within the sleeve 531. The sleeve 531 contains lubricating oil, which allows the lubricating oil inside the gas spring to automatically lubricate the piston rod 532 when the gas spring extends or retracts, thereby ensuring the performance of the gas spring. That is, when the gas spring extends or retracts, when the position of the piston rod 532 is lower than that of the sleeve 531, the lubricating oil accumulates at the lowest point of the sleeve 531 under the action of gravity. The sealing sliding point between the piston rod 532 and the sleeve 531 is approximately located on the side of the sleeve 531 near the hinge center point 2, which prevents the gas spring from having a reduced lifespan due to the lack of lubrication at the sealing sliding point inside.

[0102] By positioning the sleeve 531 above the piston rod 532, the lubricating oil can be collected at the connection between the sleeve 531 and the piston rod 532 by the gravity of the lubricating oil itself. This provides continuous lubrication for the reciprocating movement of the piston rod 532, reducing the increased friction between the piston rod 531 and the sleeve 531 caused by a lack of lubrication over a long period, which would affect the user experience and the service life of the gas spring.

[0103] It should be noted that the working principle of a gas spring is to use a 50 / 50 mixture of transformer oil and turbine oil to seal an inert gas (usually nitrogen) within a space. The inert gas acts as an elastic medium to transmit pressure, thus providing an elastic effect. When the gas spring is in operation, the pressure difference between the two sides of the piston drives the movement of the piston rod.

[0104] like Figure 3 and Figure 7 As shown, the battery compartment cover 52 has an upper cover position that flips upward to facilitate the user's access to and from the battery pack. When the battery compartment cover 52 is in the upper cover position, that is, when the battery compartment cover 52 is flipped upward to the limit position, the battery compartment cover 52 is in a fully open state, and the battery compartment is fully exposed, which makes it easy for the user to take the battery pack out of the battery compartment and also easy for the user to put the battery pack back into the battery compartment.

[0105] like Figure 4 and Figure 7As shown, the battery compartment cover 52 has a lower cover position that closes downward to close the battery compartment. When the battery compartment cover 52 is in the lower cover position, that is, when the battery compartment cover 52 is closed downward to the limit position, the battery compartment cover 52 is in a fully closed state, and the battery compartment is completely sealed, thereby fixing the battery pack inside the battery compartment and realizing the fixation and protection of the battery pack.

[0106] like Figure 7 As shown, the battery compartment cover 52 has a transition cover position located between the upper cover position and the lower cover position. When the battery compartment cover 52 is located between the upper cover position and the transition cover position, the assisting member 53 can apply a force to the battery compartment cover 52 to move it towards the upper cover position. During the upward flipping process, after the battery compartment cover 52 passes the transition cover position, it can automatically move to the upper cover position under the external force of the assisting member 53, thus achieving semi-automatic opening of the battery compartment cover 52. When the battery compartment cover 52 is located between the lower cover position and the transition cover position, the assisting member 53 can apply a force to the battery compartment cover 52 to move it towards the lower cover position. During the downward closing process, after the battery compartment cover 52 passes the transition cover position, it can automatically move to the lower cover position under the external force of the assisting member 53, thus achieving semi-automatic closing of the battery compartment cover 52.

[0107] In some optional embodiments, the maximum force of the assisting component 53 is 4Kg to 7Kg, that is, during the process of flipping the battery compartment cover 52 upward, the assisting component 53 extends and retracts in the axial direction and applies a force of 4Kg to 7Kg ​​to the battery compartment cover 52.

[0108] like Figure 12 As shown, in some optional embodiments, when the battery compartment cover 52 is located between the upper cover position and the transition cover position, the angle between the battery compartment cover 52 and the horizontal direction is C, and the angle between the axis of the gas spring and the battery compartment cover 52 is B. At this time, there are two forces acting on the battery compartment cover 52, namely the weight G of the battery compartment cover 52 and the supporting force F10 of the gas spring. The weight G of the battery compartment cover 52 is along the vertical direction, and the supporting force F10 of the gas spring is along the axial direction of the gas spring. Since the bottom end of the battery compartment cover 52 is hinged to the battery compartment body 51, the battery compartment cover 52 can only rotate around the rotation center point 1.

[0109] The supporting force F10 of the gas spring is 4 kg. According to the composition and decomposition of forces, the supporting force F10 can be decomposed into a circumferential component F11 and a radial component F12, and F11 = F10 * sinB; the weight G of the electromagnetic compartment cover 52 is 0.5 kg, and the weight G can be decomposed into a circumferential component G11 and a radial component G12, and G11 = G * cosC. The length of the battery compartment cover 52 is L. The torque generated by the supporting force F10 of the gas spring on the battery compartment cover 52 is M11, M11 = F11 * L = F10 * sinB * L. The torque generated by the weight G of the battery compartment cover 52 on the battery compartment cover 52 is M12 = G11 * L / 2 = G * cosC / 2. Therefore, M11 / M12 = 16 * sinB / cosC. That is, when sinB / sinC > 0.0625, since cosC < 1, when B > 3.5°, the battery compartment cover 52 automatically flips upward.

[0110] like Figure 13 As shown, in some optional embodiments, when the battery compartment cover 52 is located between the lower cover position and the transition cover position, two forces act on the battery compartment cover 52: the weight G of the battery compartment cover 52 and the supporting force F20 of the gas spring. The supporting force F20 of the gas spring is along the axial direction of the gas spring. Since the bottom end of the battery compartment cover 52 is hinged to the battery compartment body 51, the battery compartment cover 52 can only rotate around the rotation center point 1. The supporting force of the gas spring can be decomposed into a circumferential component F21 and a radial component F22, and the direction of the circumferential component F21 is obliquely downward. The weight of the battery compartment cover 52 is vertically downward. Therefore, under the combined action of the weight G of the battery compartment cover 52 and the supporting force F20 of the gas spring, the battery compartment cover 52 automatically flips downward.

[0111] Meanwhile, when the user manually opens the battery compartment cover 52, that is, when the battery compartment cover 52 is in the lower cover position, the battery compartment cover 52 is in a horizontal state, and the angle between the axis of the gas spring and the battery compartment cover 52 is D. At this time, there are two forces acting on the battery compartment cover 52, namely the weight G of the battery compartment cover 52 and the supporting force F20 of the gas spring. The weight G of the battery compartment cover 52 is in the vertical direction, and the supporting force F20 of the gas spring is in the axial direction of the gas spring. Since the bottom end of the battery compartment cover 52 is hinged to the battery compartment body 51, the battery compartment cover 52 can only rotate in a circle around the rotation center point 1.

[0112] The supporting force F20 of the gas spring is 4 kg, and it can be decomposed into a circumferential component F21 (vertical direction) and a radial component F22, where F21 = F20 * sinD. The weight G of the battery compartment cover 52 is 0.5 kg. The length of the battery compartment cover 52 is L. The torque generated by the supporting force F20 of the gas spring on the battery compartment cover 52 is M21, where M21 = F21 * L = F20 * sinD * L. The torque generated by the weight G of the battery compartment cover 52 on the battery compartment cover 52 is M22 = G * L / 2.

[0113] When the battery compartment cover 52 is opened manually, the user applies an opening force F30 to the battery compartment cover 52, and the opening force F30 is in the vertical direction. The torque generated by the opening force F30 on the battery compartment cover 52 is M30 = F30 * L. When M30 > M21 + M22 = F20 * sinD * L + G * L / 2, since the angle D < 3°, M21 + M22 < 0.278L, F30 = M30 / L < 0.278Kg, which is about 60% of the weight of the battery compartment cover 52. That is, it is not difficult for the user to open or close the cover manually.

[0114] like Figure 1 As shown, in one specific embodiment, a gardening operation vehicle includes a frame 10, a driving component 30, an operation component 40, and a power supply system 50; the frame 10 extends in a front-rear direction; the driving component 30 is mounted on the frame 10 for driving the vehicle to move; the operation component 40 is mounted on the frame 10 for performing gardening operations.

[0115] like Figure 1 As shown, in some optional embodiments, the working component 40 is configured as a cutting table mounted on the frame 10 for mowing operations. The cutting table can be electrically connected to the power supply system 50 to provide power for mowing operations; or, the cutting table can also be driven to a power source such as an internal combustion engine or a hydraulic pump to drive the cutting table to perform mowing operations.

[0116] like Figure 1 As shown, in some optional embodiments, the driving component 30 is configured as a drive motor and drive wheels mounted on the frame 10. Multiple drive wheels are mounted on the frame 10, and the drive motor is fixedly mounted on the frame 10 and is connected to the drive wheels for driving the vehicle to move.

[0117] like Figure 2 , Figure 3 and Figure 4As shown, in some optional embodiments, the power supply system 50 includes a battery compartment 51, a battery compartment cover 52, a battery pack, and a booster 53. The battery compartment 51 is fixedly installed above the rear of the vehicle frame 10, and the battery pack is placed in the battery compartment of the battery compartment 51. The battery compartment cover 52 is hinged to the battery compartment 51. The booster 53 is installed between the battery compartment 51 and the battery compartment cover 52, and the top end of the booster 53 is hinged to the battery compartment cover 52, and the bottom end of the booster 53 is hinged to the battery compartment 51.

[0118] like Figure 3 and Figure 7 As shown, the battery compartment cover 52 has an upper cover position that flips upward to facilitate the user's access to and from the battery pack. When the battery compartment cover 52 is in the upper cover position, that is, when the battery compartment cover 52 is flipped upward to the limit position, the battery compartment cover 52 is in a fully open state, and the battery compartment is fully exposed, which makes it easy for the user to take the battery pack out of the battery compartment and also easy for the user to put the battery pack back into the battery compartment.

[0119] like Figure 4 and Figure 7 As shown, the battery compartment cover 52 has a lower cover position that closes downward to close the battery compartment. When the battery compartment cover 52 is in the lower cover position, that is, when the battery compartment cover 52 is closed downward to the limit position, the battery compartment cover 52 is in a fully closed state, and the battery compartment is completely sealed, thereby fixing the battery pack inside the battery compartment and realizing the fixation and protection of the battery pack.

[0120] like Figure 7 As shown, the battery compartment cover 52 has a transition cover position located between the upper cover position and the lower cover position. When the battery compartment cover 52 is located between the upper cover position and the transition cover position, the assisting member 53 can apply a force to the battery compartment cover 52 to move it towards the upper cover position. During the upward flipping process, after the battery compartment cover 52 passes the transition cover position, it can automatically move to the upper cover position under the external force of the assisting member 53, thus achieving semi-automatic opening of the battery compartment cover 52. When the battery compartment cover 52 is located between the lower cover position and the transition cover position, the assisting member 53 can apply a force to the battery compartment cover 52 to move it towards the lower cover position. During the downward closing process, after the battery compartment cover 52 passes the transition cover position, it can automatically move to the lower cover position under the external force of the assisting member 53, thus achieving semi-automatic closing of the battery compartment cover 52.

[0121] like Figure 2 , Figure 3 and Figure 5As shown, in some optional embodiments, the upper surface of the battery compartment 51 is horizontally arranged, and the battery compartment of the battery compartment 51 is inclined upward towards the rear of the vehicle, that is, the battery compartment is inclined to open towards the rear, so that the battery compartment cover 52 can facilitate the user to take out and put in the battery pack with a limited opening angle.

[0122] The battery compartment 51 includes a bottom plate 511, a front side plate 512, a rear side plate 513, a left side plate, and a right side plate. The bottom plate 511 is fixedly installed at the rear of the frame 10, and the end of the bottom plate 511 near the seat 20 is higher than the end away from the seat 20. The left side plate and the right side plate are arranged vertically and fixedly connected to the bottom plate 511. The front side plate 512 and the rear side plate 513 are arranged in parallel and inclined, and the bottom ends of the front side plate 512 and the rear side plate 513 are fixedly connected to the bottom plate 511.

[0123] The battery pack is inserted into and installed in the battery compartment along a first direction, which is perpendicular to the base plate 511 and parallel to the tilting direction of the battery compartment. This first direction refers to... Figure 5 The direction of the double arrow in the image.

[0124] like Figure 5 As shown, further, the angle between the first direction and the vertical direction is A, 3°≤A≤10°, that is, the angle between the base plate 511 and the horizontal plane is A, 3°≤A≤10°.

[0125] The working process of this utility model's garden operation vehicle is as follows:

[0126] like Figure 7 As shown, the natural length of the gas spring (the straight-line distance between the hinge center point 2 and the motion center point 3) is Lmax. The gas spring can be compressed to its minimum length Lmin. The compression stroke of the gas spring is 30mm to 100mm, that is, 30mm≤Lmax-Lmin≤100mm.

[0127] When the gas spring is installed between the battery compartment body 51 and the battery compartment cover 52, the battery compartment cover 52 swings back and forth around the rotation center point 1 (rotation axis 56) under the restriction of the gas spring. When it moves to any position, the angle between the battery compartment cover 52 and the horizontal line is ω, and the dynamic length of the gas spring is L.

[0128] When the battery compartment cover 52 is opened to the transition cover position, the angle between the battery compartment cover 52 and the horizontal plane is α, and 10°≤α≤20°; when the battery compartment cover 52 is opened to the upper cover position, the angle between the battery compartment cover 52 and the horizontal plane is β, and 60°≤β≤90°.

[0129] When Lmin≤L<Lmax, there is always an elastic force inside the gas spring that stretches the gas spring to its natural state; when L=Lmax, the gas spring is already in its natural state and there is no elastic force inside.

[0130] like Figure 7 and Figure 11 As shown, when the battery compartment cover 52 is in the lower cover position, the dynamic length of the gas spring is L3, where Lmin < L3 < Lmax, indicating that the gas spring has an elastic force. Under the action of the elastic force of the gas spring, the battery compartment cover 52 always tends to rotate clockwise. After being limited by the battery compartment body 51, the battery compartment cover 52 will remain in the lower cover position. The rotation center point 1 of the cover + the hinge center point 2 of the gas spring + the motion center point 3 of the gas spring form a stable triangular structure, thereby ensuring the stability of the closed state of the cover.

[0131] like Figure 7 and Figure 10 As shown, when the battery compartment cover 52 is in the transition cover position, the dynamic length of the gas spring is L2, Lmin < L2 < Lmax, and there is an elastic force. At this time, the rotation center point 1 of the cover, the hinge center point 2 of the gas spring, and the motion center point 3 of the gas spring are on a straight line, which is an unstable state. Under the action of the elastic force, the battery compartment cover 52 may move clockwise downward or counterclockwise upward.

[0132] like Figure 7 and Figure 9 As shown, when the battery compartment cover 52 is in the upper cover position, the dynamic length of the gas spring is L1, at which point L1 = Lmax, and the gas spring is in its natural state with no internal elastic force. Under the support and limiting action of the gas spring, the battery compartment cover 52 remains in the upper cover position and cannot continue to rotate. Furthermore, the rotation center point 1 of the cover, the hinge center point of the gas spring, and the motion center point 3 of the gas spring form a stable triangular structure, thereby ensuring the stability of the cover in the open state.

[0133] After the operator manually opens the battery compartment cover 52 and rotates it past the transition cover position, they can release their hands. Under the elastic force of the gas spring, the battery compartment cover 52 will continue to rotate to the upper cover position and stop, and the battery compartment cover 52 will remain stably open in the upper cover position.

[0134] After the operator manually closes the battery compartment cover 52 and rotates it past the transition cover position, they can release their hands. Under the elastic force of the gas spring, the battery compartment cover 52 will continue to rotate to the lower cover position. After being limited by the battery compartment, the battery compartment cover 52 will remain in a stable closed state.

[0135] like Figure 1As shown in one specific embodiment, a rideable lawnmower includes a frame 10, a working component, and a power supply system 50. The frame 10 extends in a front-to-back direction, and the working component is a cutter head mounted on the frame 10 for performing lawnmowing operations. The power supply system 50 is mounted on the frame 10 and electrically connected to the cutter head for providing power for lawnmowing operations.

[0136] like Figure 2 , Figure 3 and Figure 4 As shown, the power supply system 50 includes a battery compartment body 51, a battery compartment cover 52, a battery pack, and a booster component 53. The battery compartment body 51 is fixedly installed above the rear of the vehicle frame 10, that is, the bottom of the battery compartment body 51 is fixedly connected to the rear of the vehicle frame 10, and the battery compartment body 51 has a battery compartment with a top opening, in which the battery pack is placed. The front end of the battery compartment cover 52 is hinged to the front end of the battery compartment body 51 via a rotating shaft 56. The booster component 53 is a gas spring or a gas strut. The gas spring is installed between the battery compartment body 51 and the battery compartment cover 52, that is, the top end of the gas spring is hinged to the battery compartment body 51, and the bottom end of the gas spring is hinged to the battery compartment cover 52. The battery compartment cover 52 has an upper cover position that flips up to facilitate the user to put in and take out the battery pack, a lower cover position that closes down to close the battery compartment, and a transition cover position located between the upper cover position and the lower cover position.

[0137] When the battery compartment cover 52 is located between the upper cover position and the transition cover position, the assist member 53 can apply a force to the battery compartment cover 52 to move the battery compartment cover 52 toward the upper cover position. When the battery compartment cover 52 is located between the lower cover position and the transition cover position, the assist member 53 can apply a force to the battery compartment cover 52 to move the battery compartment cover 52 toward the lower cover position.

[0138] In another specific embodiment, the working component is configured as a snow sweeping component, thus the garden vehicle is a snow sweeper; that is, the working component, as the main functional component of the garden vehicle, can be changed according to the user's selection; furthermore, in some embodiments, the aforementioned working component can also be a component that the user can replace according to actual needs, such as removing the lawnmower and replacing it with a sweeping disc, thus changing the lawnmower into a sweeper. In summary, replacing the garden working component with any functional component according to user needs should not be construed as exceeding the protection scope of this embodiment.

[0139] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
