[0001] The utility model relates to the technical field of gardening operation vehicles, in particular to an outdoor gardening tool, a riding lawn mower and a control handle of the lawn mower. [Background Technology]

[0002] Outdoor gardening operation vehicles generally refer to vehicles used for outdoor gardening operations, mainly including vehicles used for cutting and maintaining garden grass.

[0003] The lawn mower is one of the gardening vehicles that has developed rapidly in recent years. It is provided with a cutting blade for cutting and maintaining grass. The lawn mower is mostly controlled manually when working. Generally, the user holds the control handle to control the speed or direction of the lawn mower in multiple ways. When mowing the lawn, the user must keep holding the handle, and the handles in the prior art are all cylindrical structures. Although human palms are relatively flexible, they still have metacarpal bones and proximal phalanges that are not bendable and slightly long, so that the user's palm cannot maintain a high degree of fit with the cylindrical handle, which causes the user to experience obvious hand fatigue when working for a long time.

[0004] In view of this, it is indeed necessary to provide a control handle for an outdoor garden tool, a riding lawn mower, and a lawn mower to overcome the defect of the prior art that hand fatigue easily occurs when holding the handle. [Contents of the utility model]

[0055] Compared with the prior art, the utility model has the following beneficial effects:

[0056] The utility model modifies the simple cylindrical handle in the prior art into a non-cylindrical structure with a straight cross-section, thereby increasing the fit between the handle and the user's palm, improving the comfort of holding the handle, and reducing hand fatigue caused by the palm not being in full fit with the handle for a long time.

[0057] The handle of the utility model also includes a coating layer with relatively low hardness. When the coating layer is squeezed by gripping, it produces a small amount of deformation to increase the fit with the hand, thereby further improving the grip comfort of the user.

[0058] In the present invention, when the user holds the handle and makes the metacarpal bone or proximal phalanx of the palm abut against the flat area of ​​the handle, not only is the grip more comfortable, but the thumb is also in a freely stretched state and is located near the control switch. When the switch needs to be operated, the thumb can operate the switch more quickly; and because the thumb is freely stretched and located near the switch, there is no need to deliberately adjust the position of the thumb, thereby reducing the fatigue caused by the user deliberately maintaining the thumb position for a long time.

[0066] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the words "upper", "lower", "front", "back" and the like indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0067] Unless otherwise specified, the terms "disposed", "connected" and "connected" in this utility model should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. "Fixed connection" in this utility model should also be understood in a broad sense as integral molding or welding or connection through other fasteners.

[0068] See also Figure 1, shown is a lawn mower disclosed in the utility model, including a frame 1 and a cutting table, a power mechanism, a battery pack 5, and a control handle 3 arranged on the lower side of the frame 1.

[0069] The cutting platform is connected to the vehicle frame 1, and the cutting platform includes a cutting knife that rotates to produce a mowing effect on the grass; the power mechanism is connected to the vehicle frame 1, and the power mechanism is connected to the first driving wheel and the second driving wheel by transmission; the battery pack 5 is connected to the vehicle frame 1, and is used to supply power to the cutting platform and the power mechanism;

[0070] See also Figure 1 The lawn mower is provided with a first control handle and a second control handle on the left and right sides respectively. The first control handle is operably coupled to a first driving wheel of the lawn mower for rotating the first driving wheel, and the second control handle is operably coupled to a second driving wheel of the lawn mower for rotating the second driving wheel.

[0071] The power mechanism of this embodiment includes a first power mechanism connected to the first driving wheel and a second power mechanism connected to the second driving wheel. Therefore, the control method of the driving wheel is specifically as follows: when the user needs to make the first driving wheel start to rotate or adjust the speed of the first driving wheel, the user should send a corresponding signal to the power mechanism through the first control handle; when the user needs to make the second driving wheel start to rotate or adjust the speed of the second driving wheel, the user should send a corresponding signal to the power mechanism through the second control handle.

[0072] Reference Figure 2 , Attachment Figure 3 The first control handle and the second control handle both include a control handle 3 for the user to hold. The outer contour of the cross section of the control handle 3 observed along its axial direction is non-circular, and the outer contour of the cross section is a closed shape composed of arcs and straight lines connected end to end; the arcs and straight lines in the outer contour of the cross section correspond to the curved surface area and the plane area of ​​the outer wall of the handle respectively; from an anatomical perspective, the length of the metacarpal bones and proximal phalanges of humans is significantly longer than that of the middle phalanges and distal phalanges. The existence of this structure enables the palm to grasp stably under the action of muscles, but the longer characteristics of the metacarpal bones and proximal phalanges make it impossible for the hand to fully fit when grasping the cylindrical structure. Failure to fully fit will lead to relatively concentrated local stress. For people who maintain this gripping posture for a long time, it is quite easy to get hand fatigue.

[0073] The cross section along the first direction ( Figure 2 The length of the cross section along the second direction different from the first direction ( Figure 2 The length of the first direction in the embodiment is perpendicular to the second direction. That is, the length of the cross section of the control handle 3 in one direction is greater than the length in another direction, and when the user holds the control handle 3 normally, refer to the attached figure. Figure 4, the palm extends along the first direction; the fingers except the thumb are bent and partially parallel to the second direction, and at this time the fingers and the palm wrap the control handle 3 together to achieve the grip of the control handle 3. Based on the above size conditions of the control handle 3, the user's hand can have a better fit when gripping the handle, and the user's gripping action is closer to the natural stretching state of the palm, so that the user can grip the control handle 3 more comfortably, improving the user's comfort.

[0074] For further information, please refer to the attached Figure 2 , Attachment Figure 3 , the outer contour of the cross section is composed of two semicircles and two straight line segments, the diameter of the semicircle is b, and the sum of the diameter of the semicircle and the length of a straight line segment is a. In this embodiment, a=40mm, b=32mm. In other embodiments, the following options are available: a=36mm, b=27mm, or a=45mm, b=36mm. It can be seen from the accompanying drawings that the outer contour of the cross section of the control handle 3 is a waist-shaped structure with semicircles on both sides and a straight middle. It should be noted that: there are differences in the palm sizes of different users, but the palm sizes of users with similar geographical locations are roughly the same. Therefore, targeted adaptation should be carried out according to the average palm size of users in the area. For areas with larger average palms, the values ​​of a and b should be larger, and vice versa. However, if the overall condition of 3≥a / b>1 is met, the user's grip comfort can be effectively improved.

[0075] Reference Figure 4 , the figure shows a state diagram of the user's hand holding the control handle 3. As mentioned above, in this state, the user's palm position abuts the aforementioned plane area 34, and the fingers are partially bent and wrapped around the curved area 35. The palm of the human hand corresponds to the metacarpal bone and cannot bend in the extension direction of the palm, that is, the palm part is a relatively straight structure; the straight palm abutting against the plane area 34 can make the hand and the handle fit better, the relative overhead position of the hand and the handle is less, and the comfort of holding is correspondingly higher, which effectively relieves the hand fatigue caused by holding the handle for a long time.

[0076] Reference Figure 5 , the figure shows another state diagram of the user's hand holding the control handle 3. It can be seen from the figure that the user's proximal phalanx is located in contact with the aforementioned plane area 34, and the middle phalanx, distal phalanx, and metacarpal bone are located in contact with the curved surface area 35 in front and behind the plane area 34. The proximal phalanx is the section of the human finger closest to the metacarpal bone, and its length is greater than that of the middle phalanx and the distal phalanx. The proximal phalanx part of the hand is also a relatively straight structure; the straight proximal phalanx part abutting against the plane area 34 can also make the hand and the handle fit better, the middle phalanx part and the metacarpal part are respectively bent on both sides of the proximal phalanx and abut against the handle, thereby reducing the relative overhead position between the hand and the handle, and the comfort of holding is correspondingly higher.

[0077] It should be noted that the attached Figure 4 , Attachment Figure 5 The hands hold the handle in different postures, and the two holding postures also correspond to the common holding habits of most users. In the two postures, the hands respectively fit the plane area 34 with the metacarpal bones and proximal phalanges. Since these two positions of the hand are relatively long and cannot be bent, the fitting plane area 34 can effectively fit the hand and the handle, that is, the hand and the handle fit better, the holding comfort is higher, and the fatigue caused by long-term holding will be reduced.

[0078] The control handle 3 includes a shaping layer 31 for maintaining its shape. The shaping layer 31 is made of hard plastic. The control handle 3 is covered with a coating layer 32 whose hardness is less than that of the hard plastic. The hard plastic makes the basic shape of the control handle 3 stable, that is, the shape structure of the aforementioned grip comfort is basically maintained; the lower hardness of the coating layer 32 enables it to produce a small amount of deformation when it is gripped forcefully, which is used to avoid a noticeable scratchy feeling on the user's hand and further improve the grip comfort.

[0079] Specifically, the shaping layer 31 can be made of flame retardant materials such as PA6+GF30, and the coating layer 32 can be made of thermoplastic elastomer TPE / TPR. When the shaping layer 31 and the coating layer 32 are manufactured, the two are injection molded in sequence.

[0080] The control handle 3 also includes a rigid plastic part 33 which is sleeved in the shaping layer 31, and the plastic part 33 is used to limit the basic position stability of the control handle 3 relative to other parts of the lawn mower (the frame 1 of the lawn mower). From the perspective of spatial position, the control handle 3 is a part extending from the frame 1, so the rigid plastic part 33 can effectively prevent its bending, ensure the spatial position of the control handle 3, and ensure that the control handle 3 still maintains the initial position after long-term use of the lawn mower, thereby improving the reliability of the entire vehicle. In this embodiment, the maximum dimension of the outer contour of the cross section of the shaping part 33 perpendicular to the extension direction of the handle is c, 2>b / c>1, that is, the shaping part 33 is relatively thinner than the shaping layer 31. The shaping part 33 in this embodiment is made of a round tube, the lower end of which is connected to the frame 1, and the shaping layer 31 is installed on the upper end.

[0081] Again, refer to the attached Figure 4 , Attachment Figure 5 , a control switch 4 is provided at one end of the control handle 3 away from the frame 1, and the control switch 4 is configured to control the working state change of the lawn mower. That is, the control switch 4 is located at the end of the control handle 3. When the lawn mower of the present application is used normally, the user holds the control handle 3 near the control part, and the thumb is naturally stretched and close to the control switch 4 of the control part. Figure 4 and attached Figure 5In the embodiment, the control switch 4 is oriented in different directions relative to the handle, corresponding to the handle holding habits of different users. The direction of the control switch 4 should be close to the position where the thumb naturally stretches when holding the handle, thereby reducing the amount of thumb movement when the user operates the control switch 4, ensuring that the user can quickly complete the operation when the control switch 4 needs to be operated. In addition, since the human thumb is relatively flexible, it is easy to operate the control switch 4. Figure 4 , 5 For the two holding postures, the control switch 4 in the specific implementation embodiment can be centered in the middle position corresponding to the two figures. At this time, the position of the control switch 4 is also relatively close to the natural stretch state of the thumb. Not only does it not significantly increase the workload of the thumb, it also avoids the thumb accidentally touching the control switch 4 when it makes an unintentional movement. At this time, it can also adapt to more people.

[0082] The control switch 4 can control various working states of the lawn mower. Specifically, the control switch 4 is used to control the on / off of the entire or local power supply of the lawn mower.

[0083] In other embodiments, the control switch 4 can also adjust the power mechanism or the cutting table of the lawn mower, such as adjusting the speed of the power mechanism output to the drive wheel, the speed of the cutting knife in the cutting table, etc.

[0084] To sum up: in the present application, setting a straight area at the handle can make the hand and the handle fit better to a greater extent, improve the user's operating comfort when holding the handle, thereby reducing hand fatigue when using the handle of the present application for a long time.

[0085] Again, refer to the attached Figure 2 , Attachment Figure 3 It can be seen from the figure that the shaping layer 31 and the covering layer 32 of the control handle 3 are composed of two parts, the bite part 6 in the figure is a structure connecting the left and right parts, and the bite part 6 is composed of a groove opened on one side and a protrusion fixed on the other side. When the two parts of the shaping layer 31 are combined, the protrusion is inserted into the groove to achieve preliminary positioning. Figure 1 In the figure, it is obvious to see the threaded hole 7 located on one side of the control handle 3. After the two parts of the shaping layer 31 are assembled together, the two parts are locked by a bolt matched in the threaded hole 7 to complete the assembly of the two parts of the shaping layer 31. Furthermore, the shaping piece 33 can also be connected to the shaping layer 31 by the bolt.

[0086] In addition, the two parts of the shaping layer 31 are engaged with each other through the engaging portion and fixed with a bolt structure so that the connection between the two parts is relatively tight, and the gap at the connection is difficult for water or water vapor to enter, thereby protecting the circuit structure that may exist inside the shaping layer 31.

[0087] The utility model also discloses a lawn mower including a support platform, which is connected to the frame 1 and is used to support the user; Figure 1 The supporting platform in the figure is a seat 2 mounted on the frame 1, and the lawn mower is a riding lawn mower; in addition, the supporting platform can also be configured as a standing platform, and the lawn mower is a standing lawn mower. That is, it should be understood that the lawn mowers to be protected by this application include but are not limited to riding lawn mowers and standing lawn mowers.

[0088] In other embodiments of the utility model, the cutting table can also be replaced by other working parts for garden maintenance, such as snow sweeping, snow blowing, mopping, sweeping, etc. The above working parts should be connected to the frame 1 and realize corresponding functions, which correspond to other garden maintenance tools (garden maintenance vehicles).

[0089] The utility model is not limited to the above specific embodiments. A person skilled in the art can easily understand that there are many alternatives to the lawn mower and the control handle of the utility model without departing from the principle and scope of the utility model. The protection scope of the utility model shall be based on the content of the claims.
