Description

Technical Field

[0001] This utility model relates to the field of electric chainsaw technology, specifically to electric chainsaws. Background Technology

[0002] In existing electric chainsaw designs, battery packs are generally installed on the chainsaw handle using a snap-fit ​​method. For example, Chinese patent application CN218657107U discloses a battery mounting structure for a chainsaw, which uses a snap-fit ​​method to secure the battery pack. This snap-fit ​​method has poor stability; vibrations generated during chainsaw operation can cause the connection between the battery pack and the main unit to loosen, or even result in poor contact. Furthermore, the snap-fit ​​battery pack requires considerable operating space during disassembly and installation, which is not ideal for some compact working environments. Therefore, developing a more stable, convenient, and durable electric chainsaw battery pack mounting structure is an important direction for current electric chainsaw technology improvement. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] In view of the shortcomings of the prior art, this utility model provides an electric chainsaw, which solves the problems mentioned in the background art.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric chainsaw, including a chainsaw body, a support plate, and a battery compartment. A limiting component is slidably disposed on the handle of the chainsaw body. The end of the handle of the chainsaw body is rotatably connected to the support plate. A first groove is formed on the lower surface of the support plate, and the battery compartment is slidably disposed within the first groove of the support plate. A groove is formed on the support plate, and two electrodes are fixedly connected to the groove of the support plate. The chainsaw body is electrically connected to the two electrodes respectively. After the battery compartment is slidably installed inside the first groove of the support plate, the battery compartment is electrically connected to the two electrodes respectively. After the support plate rotates the battery compartment, the limiting component creates a limiting stop on the sliding end of the support plate.

[0007] Optionally, the limiting assembly includes a push plate, a connecting rod, a limiting plate, and a first spring. The handle portion of the chainsaw body has a second sliding groove. One end of the connecting rod is fixedly connected to the push plate, and the other end of the connecting rod is fixedly connected to the limiting plate. The connecting rod passes through the handle portion of the chainsaw body and the two are slidably connected. The first spring is sleeved on the outer wall of the connecting rod and is located in the second sliding groove. Both the push plate and the limiting plate are slidably connected to the handle portion of the chainsaw body.

[0008] Optionally, a second spring is fixedly connected in the groove of the support plate, and a protective plate is fixedly connected to the end of the second spring away from the support plate. The protective plate is slidably connected to the support plate through the groove.

[0009] (III) Beneficial Effects

[0010] This utility model provides an electric chainsaw, which has the following beneficial effects:

[0011] This electric chainsaw, through the coordinated arrangement of a battery compartment, support plate, limiting component, and chainsaw body, effectively secures the battery compartment. The limiting component is slidably mounted on the handle of the chainsaw body, and the support plate is mounted on the handle end of the chainsaw body with a 180-degree rotation capability. The battery compartment is slidably mounted onto the support plate. After installation, rotating the support plate 180 degrees causes the battery compartment to rotate 180 degrees as well. The limiting plate in the limiting component then restricts the battery compartment, preventing it from accidentally sliding out and thus ensuring a more stable electrical connection between the battery compartment and the chainsaw body. Compared to existing technologies, this design effectively prevents accidental battery compartment slippage; avoids unstable battery power supply after chainsaw vibration; and makes battery compartment disassembly very convenient.

[0023] Please see Figures 1 to 7 The present invention provides a technical solution: an electric chainsaw includes a chainsaw body 1, a support plate 3, and a battery compartment 13. A limit component is slidably provided on the handle of the chainsaw body 1. The end of the handle of the chainsaw body 1 is rotatably connected to the support plate 3. A first groove 4 is provided on the lower surface of the support plate 3. The battery compartment 13 is slidably disposed in the first groove 4 of the support plate 3.

[0024] The support plate 3 has a groove 11, and two electrodes 6 are fixedly connected in the groove 11 of the support plate 3. The chainsaw body 1 is electrically connected to the two electrodes 6 respectively.

[0025] After the battery compartment 13 is slidably installed inside the first groove 4 of the support plate 3, the battery compartment 13 is electrically connected to the two electrodes 6 respectively. After the support plate 3 drives the battery compartment 13 to rotate 180 degrees, the limiting component creates a limiting block on the sliding end of the support plate 3.

[0026] In this design, the chainsaw body 1 refers to the main body of the electric chainsaw, which can be a chainsaw as described in the prior art with publication number CN218657107U. The battery compartment 13 is also known as the battery pack. The support plate 3 is used to fix the battery compartment 13. The battery compartment 13 is slidably mounted on the support plate 3 via the first slide groove 4. After the support plate 3 rotates 180 degrees, the sliding end of the support plate 3 is limited and blocked by a limiting component, which prevents the battery compartment 13 from sliding out of the first slide groove 4 of the support plate 3.

[0027] The two electrodes 6 are conductors used to conduct electricity to the positive and negative electrodes of the battery compartment 13. The battery compartment 13 is electrically connected to the chainsaw body 1 through the two electrodes 6, and the battery compartment 13 supplies power to the chainsaw body 1 through the two electrodes 6.

[0028] Specifically, the limiting assembly includes a push plate 2, a connecting rod 8, a limiting plate 7, and a first spring 10. A second sliding groove 9 is provided on the handle portion of the chainsaw body 1. One end of the connecting rod 8 is fixedly connected to the push plate 2, and the other end of the connecting rod 8 is fixedly connected to the limiting plate 7. The connecting rod 8 passes through the handle portion of the chainsaw body 1 and the two are slidably connected. The first spring 10 is sleeved on the outer wall of the connecting rod 8 and is located within the second sliding groove 9. Both the push plate 2 and the limiting plate 7 are slidably connected to the handle portion of the chainsaw body 1.

[0029] One end of the first spring 10 is fixedly connected to the handle of the chainsaw body 1, and the other end of the first spring 10 is fixedly connected to the limiting plate 7. When the push plate 2 is pressed on the handle of the chainsaw body 1, the push plate 2 drives the limiting plate 7 to move through the connecting rod 8. The limiting plate 7 slides away from the second slide groove 9, and the distance between the limiting plate 7 and the support plate 3 gradually increases. The limiting plate 7 cancels its limiting and blocking effect on the support plate 3. At this time, the limiting plate 7 returns to its original position after rotating 180 degrees in the opposite direction. The sliding end of the support plate 3 is exposed, and the battery compartment 13 is slid out from the support plate 3, thereby realizing the disassembly of the battery compartment 13.

[0030] When the push plate 2 is no longer pressed, the first spring 10 elastically pulls the limiting plate 7 to reset and retract into the second slide groove 9.

[0031] Specifically, a second spring 12 is fixedly connected in the groove 11 of the support plate 3, and a protective plate 5 is fixedly connected to the end of the second spring 12 away from the support plate 3. The protective plate 5 is slidably connected to the support plate 3 through the groove 11.

[0032] The protective plate 5 has a sloping sidewall. The protective plate 5 protects the two electrodes 6, preventing damage caused by direct exposure. When the battery compartment 13 is slidably installed into the first groove 4 of the support plate 3, the battery compartment 13 moves along the sloping surface of the protective plate 5 and presses against it. The protective plate 5 compresses the second spring 12 and retracts into the groove 11. After the protective plate 5 retracts into the groove 11, the lower end of the electrode 6 is exposed. After the battery compartment 13 is fully slidably installed onto the support plate 3, the battery compartment 13 is electrically connected to the exposed end of the electrode 6.

[0033] When the battery compartment 13 slides out of the first groove 4 of the support plate 3, the protection plate 5 loses pressure, and the second spring 12 elastically pushes the protection plate 5 down, and the protection plate 5 blocks the lower end of the electrode 6.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
