Description

Electric lawn mower

The invention relates to an electric lawn mower.

In recent years, with the rising awareness of environmental protection, lawn mowers have generally used electric lawn mowers to replace fuel lawn mowers. Electric lawn mowers have the advantages of low noise, no exhaust pollution and avoiding fuel leakage and fire. Known electric lawn mowers use one hand to hold the rod body between the base and the control handle, and the other hand to hold the control handle to control the motor to operate. The electric lawn mower disclosed by TWM526804 belongs to this class. However, when such conventional electric lawn mowers are used, the linear extension length of the control handle and the rod body is too long, so that the elbow held by the control handle must be greatly bent and the wrist must also be bent before it can be smoothly held Holding the control handle will cause muscle and joint pain after a period of use, and you need to take a rest before continuing to work. This will lead to a decrease in work efficiency, and long-term use will cause occupational injuries such as joint injuries.

Therefore, there is another lawn mower on the market, as shown in Figure 6 of Patent No. WO2012/095029A1, which bends the control handle so that the user's elbow can be held only by a slight bend Control the handle for mowing, which can slightly reduce the load on the muscle joints of the wrist and elbow. However, the bending of the control handle of this lawnmower only makes the relative height of the control handle slightly lower, so the load on the elbow and wrist is still quite heavy. In addition, the control handle is bent due to the control button switch and wiring. The structure will cause insufficient strength, so it is easy to cause the control handle structure to be fatigued and bent sharply after a period of use of the lawnmower, resulting in damage to the control button or broken wiring, there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive electric lawn mower to solve the above problems.

The main purpose of the present invention is to provide an electric lawn mower that can be held by the user in a more ergonomic way for long-term work without causing muscle and joint pain, so as to increase work Efficiency and avoid occupational injuries such as joint injuries, and make the structure of the control handle more durable.

To achieve the above object, the present invention provides an electric lawn mower, which includes a straight rod section, a grip section and a head. The grip section is provided at one end of the straight rod section, the grip section is provided with a control handle, and there is a first included angle between the length direction of the grip section and the longitudinal direction of the straight rod section, the first included angle is between Between 25 degrees and 65 degrees, the grip section includes a bending rod, the bending rod is connected between the straight rod section and the control handle, the bending rod and the straight rod section form the first An angle. The seat is disposed at one end of the straight rod section opposite to the grip section, and includes a rotating motor with a rotating shaft, and a second included angle between a rotating radial direction of the rotating shaft and the length direction of the straight rod section The second included angle is between 25 degrees and 65 degrees.

The following merely illustrates the possible implementation forms of the present invention with examples, but it is not intended to limit the scope of the invention to be protected, and will be described first.

Please refer to FIGS. 1 to 3, which show a preferred embodiment of the present invention. The electric lawn mower of the present invention includes a straight rod section 1, a grip section 2 and a head 3.

The grip section 2 is provided at one end of the straight rod section 1, the grip section 2 is provided with a control handle 21, and a first included angle between the length direction of the grip section 2 and the length direction of the straight rod section 1 Θ1, the first included angle Θ1 is between 25 degrees and 65 degrees, the grip section 2 includes a bending rod 22, the bending rod 22 is connected between the straight rod section 1 and the control handle 21, the The first included angle Θ1 is formed between the bending rod 22 and the straight rod segment 1.

The seat 3 is disposed at one end of the straight rod section 1 opposite to the grip section 2 and includes a rotating motor 31 having a rotating shaft 32. One of the rotating shafts 32 rotates radially 33 and the straight rod section 1. There is a second included angle Θ2 between the longitudinal directions. The second included angle Θ2 is between 25 degrees and 65 degrees.

Preferably, the first included angle Θ1 and the second included angle Θ2 are between 30 degrees and 45 degrees, the first included angle Θ1 and the second included angle Θ2 have the same angle, and the grip section 2 is opposite to the straight rod section 1 is bent away from the seat 3, the seat 3 is bent away from the straight rod section 1 away from the grip section 2, in this embodiment, the first included angle Θ1 and the second included angle Θ2 are 35 Degree, so that the user’s elbows and wrists held in the grip section 2 can be held in the straightened state without bending, and the user’s arm muscles need less effort, so they can work for a long time without It will cause pain in the muscles and joints of the user's arm to increase work efficiency In addition, because the bending bar 22 is an integrated structure with high strength, when the electric lawn mower is in use, the control handle 21 receives less stress, and the stress is mostly concentrated on the bending bar 22, so the control handle can be avoided 21 Damaged by bending.

Specifically, the control handle 21 is disposed at one end of the grip section 2 away from the straight rod section 1. The control handle 21 is provided with a handle 211, a control key 212 is provided on the handle 211, and the control handle 21 is further provided with a bow 213 surrounding the control key 212. Press 211 and press the control key 212 to control the operation of the rotating motor 31.

The length of the control handle 21 defines a first length L1, and the length of the bending rod 22 defines a second length L2, and the ratio of the first length L1 to the second length L2 is between 4:2 and 5 :2, which is 4.5:2 in this example.

In detail, the electric lawn mower further includes a first rod body 11 and a second rod body 12, one end of the first rod body 11 is connected to the seat 3, and the other end of the first rod body 11 is connected to The second rod body 12 is sleeved together, and the bending rod 22 is integrally connected to one end of the second rod body 12 away from the first rod body 11 to have strong structural strength.

Preferably, the second rod body 12 is further provided with a handle 4 which is held by the user's other hand. The distance between the handle 4 and the handle section 2 defines a third length L3. The length of segment 2 is defined as a fourth length L4. The ratio of the third length L3 to the fourth length L4 is 3.5:6.5. This ratio allows the user’s elbows and wrists to be in a straight state to reduce For the burden of two elbows and two wrists, the user only needs to hold the handle 4 and the control handle 21 with the force of the palm of the hand, so that the two arms can be relaxed to improve the working time.

It is also worth mentioning that the length of the straight rod segment 1 defines a fifth length L5. The ratio of the fifth length L5 to the fourth length L4 is between 19.5:6.5 to 16.5:6.5. In this embodiment, it is 18:6.5, allowing the user to hold the handle 4 and the control handle 21, the weight of the grip section 2 and the seat head 3 can be maintained at a balance to maintain the grip section 2 in the horizontal direction, The burden of holding the wrist of the control handle 21 is reduced.

In summary, in the electric lawn mower of the present invention, the user's elbows and wrists can be held in the straightened state without bending, and the user's arm muscles need less effort, so they can work for a long time. It will not cause pain in the muscles and joints of the user's arms, so as to increase work efficiency, and when the electric lawn mower is in use, the control handle 21 is less stressed, and the stress is mostly concentrated on the bending rod 22, so The control handle 21 can be prevented from being damaged due to force bending.
