Technical Field

[0001] The invention belongs to the technical field of riding lawn mowers, and in particular relates to a riding lawn mower with a quick-changeable battery pack. Background Art

[0002] Electric riding lawn mowers are large-scale lawn mowers. Compared with conventional push lawn mowers, they have advantages such as high efficiency, fast mowing, and labor saving when mowing large lawns. Existing electric riding lawn mowers are still charged in the traditional parking charging method, but due to their high power consumption and long charging time, the mowing efficiency is seriously affected. The installation method of small-capacity plug-in battery packs is not suitable for such large-capacity battery packs.

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0030] Example 1

[0031] like Figure 1-3 and Figure 6 As shown, a riding lawn mower with a quick-change battery pack includes a frame 1 and a battery pack 2. A limit sliding outer frame 3 and a battery mounting seat 4 are provided on the frame 1. The battery pack 2 is slidingly connected to the limit sliding outer frame 3. A battery plug connector 11 is provided on the battery mounting seat 4. Multiple line connectors of the battery pack 2 are integrated into one battery plug connector 11. The battery pack 2 is provided with an output port 21 that matches the battery plug connector 11. The battery pack 2 is detachably fixed to the frame 1 by a fixing mechanism 5. The fixing mechanism 5 includes a telescopic positioning pin 51.

[0032] In the present invention, the battery pack 2 can quickly enter the accommodating cavity by sliding along the limit sliding outer frame 3 and dock with the battery plug connector 11 on the battery mounting seat 4; the limit sliding outer frame 3 can limit the sliding direction and position of the battery pack 2, which is convenient for accurate installation of the battery pack 2; the battery pack 2 can be conveniently fixed or removed by setting the fixing mechanism 5. Multiple wire-dropping connectors of the battery pack 2 are integrated on an output port 21, which is convenient for quick plugging and unplugging of the battery pack 2.

[0033] Example 2

[0034] like Figure 2-7 As shown, the difference between this embodiment and the first embodiment is that: a fixed cover 52 is fixedly connected to the battery pack 2, and a telescopic positioning pin 51 is slidably connected inside the fixed cover 52. A positioning hole is opened on the frame 1, and the telescopic positioning pin 51 extends out of the battery pack 2 and is inserted into the positioning hole. The side of the telescopic positioning pin 51 away from the positioning hole is connected to the fixed cover 52 through a return spring 53. The fixed cover 52 is arranged at the end of the battery pack 2 away from the battery mounting plate. When the battery pack 2 is pushed into the mounting cavity, the positioning pin is compressed. When the desired mounting position is reached, the positioning pin automatically extends and enters the mounting hole to realize the installation of the battery pack 2. The positioning pin helps to accurately position the battery pack 2 during the installation process.

[0035] The mounting seat is provided with a sliding column, and the floating mounting plate 41 is slidably connected to the sliding column. A fixed block is provided at the end of the sliding column, and the sliding distance of the floating mounting plate 41 is limited by the fixed block. The battery plug connector 11 is fixed to the floating mounting plate 41 by screws. The direction of the sliding column is the same as the sliding direction of the battery pack 2 in the limited sliding outer frame 3. There are many ways for the sliding of the floating plate mounting plate 41 on the sliding column to adapt to the plugging of the mounting package 2. In this embodiment, a spring is provided between the mounting plate 41 and the mounting seat, and the spring is adjusted on the periphery of the sliding column. Therefore, the battery plug connector 11 is in a floating state through the sliding of the floating mounting plate 41. During the pushing process of the battery pack 2, the battery plug connector 11 can adapt to the output port 21 on the battery pack 2, reducing the requirements for the assembly size.

[0036] An elastic shock absorbing member 6 is provided on the side of the battery mounting seat 4 facing the battery pack 2. The elastic shock absorbing member 6 is a shock absorbing spring or elastic material, and in this embodiment, a shock absorbing spring. A battery pack limit block 7 is provided on the battery pack 2, and the battery pack limit block 7 is provided between the elastic shock absorbing member 6 and the battery pack 2. When the battery pack 2 is inserted into the accommodating cavity, the shock absorbing spring can play a buffering role, and can assist in ejection when the battery pack 2 is pulled out.

[0037] The battery pack 2 is provided with a handle 22, which is arranged at one end of the battery pack 2 away from the battery mounting seat 4. During the process of pulling out the battery pack 2, after the shock absorbing spring assists the battery pack 2 to be ejected, the handle 22 can be pulled outwards to facilitate the removal of the battery pack 2.

[0038] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0039] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
