Description

Technical Field

[0001] This application belongs to the field of power tool technology, specifically relating to an electric chainsaw. Background Technology

[0002] An electric chainsaw is a chainsaw tool powered by electricity, widely used in wood cutting, garden pruning, and other fields. However, existing electric chainsaws suffer from poorly designed air vents. When the operator holds the chainsaw with the vent in place, it is easy to block the vent, reducing the airflow area, decreasing air volume, and affecting ventilation efficiency. This prevents the chainsaw from effectively guiding airflow to remove heat. Under high load conditions, core components such as the motor tend to accumulate heat, making it difficult for the chainsaw to maintain stable operation and significantly shortening the lifespan of these core components.

[0003] Therefore, it is necessary to provide an electric chainsaw to address the aforementioned technical problems.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0046] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0049] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0050] Reference Figures 1-5As shown, the electric chainsaw in this application includes a housing 3, a motor 1, an air outlet 4, a first air inlet 5, and a fan 2. The housing 3 includes a main body 31, a first grip 32, and a second grip 33; the motor 1 is mounted in the first grip 32; the air outlet 4 is located on the side of the first grip 32 near the second grip 33; the first air inlet 5 is located on the housing 3; the fan 2 is mounted on the output shaft 10 of the motor 1 and located at the end of the motor 1 away from the main body 31. The fan 2 is configured to be driven by the motor 1 to generate a first airflow F1 that flows in from the first air inlet 5 and flows out from the air outlet 4. The motor 1 and fan 2 in the electric chainsaw can both adopt existing technologies and solutions, which will not be described in detail here. By positioning the air outlet 4 on the side of the first grip 32 near the second grip 33, the operator's hand can be prevented from covering the air outlet 4. This ensures that the air outlet area is not reduced for heat dissipation while also preventing the hot airflow F1 from affecting the operator's hand. During the operation of the chainsaw, the fan 2 is driven by the motor 1 to generate a first airflow F1 with a specific direction. This airflow F1 passes through the motor 1 and then through the fan 2 before exiting the housing 3, carrying away the heat generated during the motor 1's operation and preventing heat concentration. This helps the chainsaw maintain stable performance under high load conditions and extends the service life of the motor 1.

[0051] Specifically, refer to Figure 5 , Figures 6a to 6d As shown, the first grip portion 32 in this embodiment includes an end plate 321, a top plate 322 away from the second grip portion 33, a bottom plate 323 near the second grip portion 33, and a side plate 324. The side plate 324 connects the end plate 321, the top plate 322, and the bottom plate 323. The air outlet 4 is located on the bottom plate 323. When the operator's hands grip the first grip portion 32 and the second grip portion 33 respectively, the hand gripping the first grip portion 32 will only cover the end plate 321, the top plate 322, and at least part of the side plate 324. The air outlet 4 is located on the bottom plate 323, which can effectively prevent the operator's hands from blocking the air outlet 4, ensuring sufficient air outlet area, facilitating a stable flow of gas from the air outlet 4 for rapid and effective heat dissipation.

[0052] Reference Figure 5 , Figures 6a-6dAs shown, the housing 3 in this application includes a first housing and a second housing disposed opposite to each other. The top plate 322 includes a first top plate 3221 located on the first housing and a second top plate 3222 located on the second housing, with the first top plate 3221 and the second top plate 3222 disposed adjacent to each other. The bottom plate 323 includes a first bottom plate 3231 located on the first housing and a second bottom plate 3232 located on the second housing, with the first bottom plate 3231 and the second bottom plate 3232 disposed adjacent to each other. The side plate 324 includes a first side plate 3241 located on the first housing and a second side plate 3242 located on the second housing, with the first side plate 3241 and the second side plate 3242 disposed opposite to each other. At least one of the first bottom plate 3231 and the second bottom plate 3232 is provided with an air outlet 4. (Refer to...) Figures 6a-6c As shown, compared to designs where only the first base plate 3231 or the second base plate 3232 has an air outlet 4, this embodiment has air outlets 4 on both the first base plate 3231 and the second base plate 3232. This design increases the air outlet area and facilitates heat dissipation. Preferably, compared to designs where there is a gap between the air outlets 4 on the first base plate 3231 and the second base plate 3232, [referring to...] Figure 6d As shown, the air outlet 4 on the first base plate 3231 and the air outlet 4 on the second base plate 3232 in this application both extend to cover the parting line, so that the two air outlets 4 are connected to form a large air outlet 4, which covers the first base plate 3231 and the second base plate 3232, and can further increase the area of ​​the air outlet 4.

[0053] Preferably, the air outlet 4 in this application at least partially covers the base plate 323 and / or the side plate 324. Compared to a solution where only the air outlet 4 on the first base plate 3231 or the second base plate 3232 covers the base plate 323 and the side plate 324, see... Figures 6e-6g As shown, in this embodiment, at least one of the air outlets 4 on the first base plate 3231 and the second base plate 3232 covers the base plate 323 and the side plate 324, which can increase the air outlet area and facilitate air dissipation. Preferably, referring to... Figures 6h~6j As shown, when the air outlet 4 is provided with one and covers the first base plate 3231 and the second base plate 3232, the air outlet 4 can cover the first side plate 3241, or the second side plate 3242, or the first side plate 3241 and the second side plate 3242, which can further increase the area of ​​the air outlet 4.

[0054] It needs to be explained that when the high-speed first airflow F1 impacts the edge of the air outlet 4 or other obstacles perpendicularly, the direction of the first airflow F1 changes suddenly, easily forming vortices; in addition, when the first airflow F1 enters an open space from the narrow air outlet 4, the sudden drop in speed leads to energy dissipation and induces turbulence. Therefore, referring to... Figure 3 , Figure 5As shown, in this embodiment, the portion of the air outlet 4 extending onto the side plate 324 gradually moves away from the end plate 321 in the direction from the bottom plate 323 to the top plate 322. This design allows the air outlet 4 to be angled relative to the first grip portion 32. This angled design causes the first airflow F1 to gradually change direction, rather than abruptly changing at a right angle, reducing the violent collision between the first airflow F1 and the edge of the air outlet 4, and decreasing vortex generation. Simultaneously, the angled air outlet 4 guides the first airflow F1 away from the fan 2, reducing hot air recirculation (i.e., the first airflow F1 being drawn into the fan 2 for secondary circulation).

[0055] Reference Figure 2 , Figure 4 As shown, in this embodiment, the first air inlet 5 is located on the side of the motor 1 away from the fan 2, and the air outlet 4 is close to the air outlet side of the fan 2. By setting the air outlet 4 close to the air outlet side of the fan 2 and the first air inlet 5 on the side of the motor 1 away from the fan 2, the air duct design inside the housing 3 is reasonable, which facilitates the formation of the first airflow F1 by the fan 2. The first airflow F1 can be effectively guided so that the first airflow F1 can pass through the motor 1 and then through the fan 2 and flow out of the housing 3 structure, avoiding hot air backflow, thereby removing the heat generated during the driving process of the motor 1, avoiding heat concentration, so that the electric chainsaw can maintain stable performance under high load conditions and extend the service life of the motor 1.

[0056] To increase the area of ​​the air outlet 4 and facilitate increased airflow for heat dissipation, a plurality of air outlets 4 are provided at intervals along the axis of the motor 1 on the first gripping part 32 in this embodiment. For example, refer to... Figure 3 , Figure 6a As shown, in this embodiment, the first grip portion 32 has three air outlets 4 spaced apart along the axis of the motor 1. Of course, in other embodiments, the first grip portion 32 may have two, four, or five air outlets 4 spaced apart along the axis of the motor 1, etc. In this embodiment, the first grip portion 32 has multiple air outlets 4 spaced apart along the rotation direction of the motor 1. For example, in this embodiment, the first grip portion 32 has two air outlets 4 spaced apart along the rotation direction of the motor 1. Of course, in other embodiments, the first grip portion 32 may have three, four, or five air outlets 4 spaced apart along the rotation direction of the motor 1, etc. This application does not limit the number of air outlets 4, as long as the size of the housing 3 is sufficient to allow the air outlets 4 to be positioned on the side of the first grip portion 32 near the second grip portion 33.

[0057] To facilitate the installation of motor 1 and prevent motor 1 from moving inside the housing 3 during operation, refer to... Figure 1 , Figure 5As shown, the motor 1 in this embodiment includes a housing 11, and a partition 325 is provided on the inner wall of the first gripping part 32, which abuts against the housing 11. The partition 325 can be a plurality of ribs spaced apart on the inner wall of the first gripping part 32, or it can be two partitions respectively provided on the first gripping parts 32 of the first housing and the second housing, with the ends of the two partitions aligned and contacting each other. The plurality of ribs or the two partitions enclose a mounting area slightly larger than the housing 11, facilitating better installation of the motor 1.

[0058] Preferably, refer to Figure 1 , Figure 5 As shown, the motor 1 in this embodiment also includes a stator assembly and a rotor assembly 12 disposed in the housing 11. The partition 325 and the housing 11 divide the internal space of the first gripping part 32 into a first cavity and a second cavity. The fan 2 is disposed in the first cavity, and the first cavity and the second cavity are connected through the gap between the stator assembly and the rotor assembly 12. When the motor 1 is in operation, a large amount of heat accumulates on the stator assembly and the rotor assembly 12. The partition 325 blocks the first airflow F1 from flowing through the gap between the outer wall of the housing 11 and the inner wall of the first gripping part 32, limiting the first airflow F1 to flow through the motor 1 only through the gap between the stator assembly and the rotor assembly 12, so that the heat inside the motor 1 can be better carried out of the housing 3 by the first airflow F1.

[0059] Existing electric chainsaws have a blocking part inside the housing where the controller is installed, which prevents airflow from passing through the controller and affects its heat dissipation. To improve the heat dissipation of the controller 6, refer to... Figure 2 , Figure 7 As shown, the electric chainsaw in this embodiment also includes a controller 6 disposed in the second grip 33. The second grip 33 has a second air inlet 7 connected to the air outlet 4. The second air inlet 7 is located beside the controller 6. The fan 2 is configured to be driven by the motor 1 to rotate and generate a second airflow F2 that flows in from the second air inlet 7 and flows out from the air outlet 4. The controller 6 can adopt existing technology and will not be described in detail here.

[0060] Reference Figure 4As shown, in this embodiment, the included angle α1 between the axis L1 of the first gripping part 32 and the axis L3 of the main body 31 is an obtuse angle, and the included angle α2 between the axis L2 of the second gripping part 33 and the axis L3 of the main body 31 is an obtuse angle. When the operator lifts the chainsaw, keeping the cutting assembly connected to the main body 31 in a relatively horizontal position, the first gripping part 32 of the chainsaw is positioned above the second gripping part 33. The cutting assembly can employ existing technologies and will not be described in detail here. When the included angle α1 between the axis L1 of the first gripping part 32 and the axis L3 of the main body 31 is an obtuse angle, and the included angle α2 between the axis L2 of the second gripping part 33 and the axis L3 of the main body 31 is an obtuse angle, the first gripping part 32 is tilted upwards, and the second gripping part 33 is tilted downwards.

[0061] The operator can grip the first grip 32 with one hand and the second grip 33 with the other. Vibrational energy is dispersed through multi-point contact between the palm and the first and second grips 32 and 33. The operator can apply downward pressure through the first grip 32 and provide forward propulsion through the second grip 33, facilitating continuous sawing and reducing shoulder and neck fatigue during prolonged logging operations. Understandably, when a person naturally raises their arm, the wrist and palm are not perfectly perpendicular but slightly tilted inward. The tilted design of the first and second grips 32 and 33 aligns their tilt direction with the natural orientation of the arm bones, allowing the operator to quickly align the chainsaw with the target without conscious adjustment. It also better conforms to the natural bending angle of the palm, enhancing the fit between the hand and thumb, preventing slippage, and improving control and comfort.

[0062] Preferably, refer to Figure 4 As shown, in this embodiment, the included angle α3 between the axis L1 of the first grip 32 and the axis L2 of the second grip 33 is an acute angle. When the operator lifts the chainsaw, keeping the cutting assembly connected to the main body 31 relatively horizontal, both the first grip 32 and the second grip 33 are tilted towards the operator. When the operator grips the chainsaw with both hands, their hands are close to their body, forming a compact force-generating posture, suitable for precise operation. At the same time, the coordinated force exerted by both hands can quickly counteract the recoil force, reducing the risk of loss of control. In addition, the arms are naturally bent, which can reduce shoulder and elbow fatigue, making it suitable for long-term operation.

[0063] Reference Figure 4As shown, the electric chainsaw in this embodiment also includes a gearbox 8 disposed in the main body 31. The gearbox 8 is linked to the motor 1, and the axis of the motor 1 intersects with the axis L2 of the second grip 33 within the range of the gearbox 8. In this embodiment, the axis of the motor 1 is approximately coincident with the axis L1 of the first grip 32. The gearbox 8 is one of the weight concentration areas of the electric chainsaw. The intersection of the axis of the motor 1 and the axis L2 of the second grip 33 here brings the operator's hands closer to the center of gravity of the equipment, allowing the operator's force to be converted into cutting force more efficiently, reducing energy loss, improving overall balance, and reducing fatigue during long-term operation.

[0064] It should be noted that the structures of motor 1, fan 2, gearbox 8, etc., which are not described in detail in this application, can all adopt existing solutions in the prior art, which can be understood and accepted by those skilled in the art, and therefore will not be described in detail.
