[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The battery pack fixing structure for a weeder involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a battery pack fixing structure for a weeder, such as Figure 1 - Figure 4 As shown, the device includes a mounting housing 1. Four support feet 2 are fixedly connected to the bottom of the mounting housing 1. Four limiting rods 3 are fixedly connected to one side of the bottom of the inner cavity of the mounting housing 1. A shock-absorbing ring 4 is fixedly connected to the other side of the bottom of the inner cavity of the mounting housing 1. Four fixing components 5 are provided at the top of the mounting housing 1. A protective net 6 is provided between the mounting housing 1 and the fixing components 5. A battery pack base plate 7 is provided in the inner cavity of the mounting housing 1. Foot pads 8 are fixedly connected to the bottom of the support feet 2. A battery pack cover 9 is provided at the top of the battery pack base plate 7. The battery pack is installed between the battery pack base plate 7 and the battery pack cover 9. The battery pack cover 9 protects the battery pack body. After the battery pack is fixed, it is installed in the designated position inside the weeder through the mounting housing 1. At the same time, the support feet 2 support the bottom position of the mounting housing 1.

[0022] Furthermore, such as Figure 1 and Figure 3 As shown, the fixing component 5 includes a fixing plate 51 fixedly connected to the top of the mounting housing 1. One end of the fixing plate 51 is fixedly connected to a limiting plate 52, and a buffer pad 53 is provided at the bottom end of the limiting plate 52.

[0023] Furthermore, such as Figure 3 As shown, the limiting plate 52 and the buffer pad 53 are both provided with connecting holes 54 in the middle. A spring 55 is provided in the inner cavity of the connecting hole 54, and a fixing bolt 56 is provided in the inner cavity of the connecting hole 54. The fixing bolt 56 passes through the inner cavity of the two connecting holes 54, and the position of the limiting plate 52 and the buffer pad 53 is fixed by the fixing bolt 56 passing through the inner cavity of the two connecting holes 54.

[0024] Furthermore, such as Figure 1 and Figure 3 As shown, the four fixing components 5 are arranged in a rectangular array. The buffer pad 53 is located at the top of the battery pack cover 9. The spring 55 is sleeved on the outer surface of the fixing bolt 56. The spring 55 effectively increases the tightness of the fixing bolt 56. The position of the battery pack cover 9 is fixed by the limiting plate 52 and the buffer pad 53, and the protective net 6 is reinforced. The protective net 6 protects the inner cavity of the mounting shell 1, preventing grass clippings generated during the use of the lawnmower from splashing into the inner cavity of the mounting shell 1, and ensuring the heat dissipation of the battery. At the same time, the buffer pad 53 is made of soft material. The buffer pad 53 prevents the lawnmower from vibrating continuously, which would cause the fixing components 5 and the battery pack cover 9 to rub against each other and become loose, affecting the stability of the battery pack installation.

[0025] Furthermore, such as Figure 2 and Figure 4 As shown, the shock-absorbing ring 4 is located between the four limiting rods 3, and the battery pack bottom plate 7 is located between the four limiting rods 3 and at the top of the shock-absorbing ring 4. The four limiting rods 3 limit the position of the battery pack bottom plate 7 around its perimeter, ensuring the accuracy of the battery pack installation position. At the same time, together with the shock-absorbing ring 4 at its bottom, it effectively reduces the vibration generated during the use of the weed cutter, which may cause the battery pack to vibrate strongly or shift its position during use.

[0026] Furthermore, such as Figure 3 and Figure 4 As shown, a sealing ring 10 is fixedly connected to the top of the battery pack base plate 7. The battery pack base plate 7 is connected to the inner cavity of the battery pack outer cover 9 through the sealing ring 10. Several connectors 11 are provided at the connection between the battery pack base plate 7 and the battery pack outer cover 9. The sealing ring 10 ensures the sealing of the connection between the battery pack base plate 7 and the battery pack outer cover 9, preventing water mist and other substances generated during the use of the weeder from entering the inner cavity of the battery pack outer cover 9 and accumulating, causing a short circuit in the battery pack. The double protection of the battery pack outer cover 9 and the mounting shell 1 effectively increases the stability of the battery pack during the use of the weeder. At the same time, the space between the battery pack outer cover 9 and the mounting shell 1 is set as a heat dissipation cavity to prevent heat accumulation in the battery pack installed inside the battery pack outer cover 9 and avoid excessive heat affecting its normal use.

[0027] Furthermore, such as Figure 4As shown, both ends of the support foot 2 are provided with first mounting holes 12. The inner wall of the support foot 2 is fixedly connected to the mounting plate 13, and the mounting plate 13 is provided with second mounting holes 14. The mounting shell 1 with the battery pack installed is fixed to the designated installation position in the inner cavity of the weeder through the four support feet 2 at the bottom. According to the specific situation of the installation position, the first mounting hole 12 and the second mounting hole 14 at the corresponding position are selected for fixing to ensure the stability and firmness of the installation position of the mounting shell 1. At the same time, the foot pads 8 at the bottom of the support foot 2 are made of soft material to reduce the impact of vibration on the mounting shell 1 during use.

[0028] The working principle of this utility model is as follows: First, the battery pack is installed on the battery pack base plate 7. The battery pack outer cover 9 is connected to the battery pack base plate 7 through a sealing ring 10. Several connectors 11 are used to fix the connection between the battery pack base plate 7 and the battery pack outer cover 9. The sealing ring 10 ensures the airtightness between the battery pack base plate 7 and the battery pack outer cover 9 to prevent water mist generated during the use of the lawnmower from entering. After the battery pack is fixed, the entire structure is placed into the inner cavity of the mounting shell 1 through the battery pack base plate 7. Four limiting rods 3 at the bottom of the inner cavity of the mounting shell 1 limit its position. At the same time, a shock-absorbing ring 4 is provided to provide shock absorption for the battery pack. After the battery pack structure is placed, four fixing components 5 are fixed to the top of the mounting shell 1 and the battery pack outer cover 9. Fixing bolts 56 penetrate the inner cavity of the two connecting holes 54 to fix the position of the limiting plate 52 and the buffer pad 53. The battery pack cover 9 is fixed in position, and the protective net 6 is reinforced. The protective net 6 protects the inner cavity of the mounting shell 1, preventing grass clippings generated during the use of the lawnmower from splashing into the inner cavity of the mounting shell 1. At the same time, the buffer pad 53 is made of soft material to prevent the lawnmower from vibrating continuously, causing the fixing component 5 and the battery pack cover 9 to rub against each other and become loose, affecting the stability of the battery pack installation. The double protection of the mounting shell 1 and the battery pack cover 9 effectively increases the stability of the battery pack during the use of the lawnmower. At the same time, the space between the battery pack cover 9 and the mounting shell 1 is set as a heat dissipation cavity to prevent heat accumulation in the battery pack installed in the battery pack cover 9, and to prevent excessive heat from affecting its normal use. After fixing, the mounting shell 1 is fixed in the designated installation position in the lawnmower. The four support feet 2 at the bottom increase the support strength of the bottom structure of the mounting shell 1.
