Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a controller assembly for a high-pressure brushless chainsaw. Background Technology

[0002] Traditional high-pressure brushless chainsaws typically use two controllers to drive the entire machine.

[0003] One of the controllers is located inside the chainsaw and is used to control the opening and closing of the drive components as well as speed adjustment.

[0004] Another controller is used to rectify the input power. The controller that controls the input power is usually placed outside the chainsaw so that it can be easily connected to the input power.

[0005] Under high-power load conditions, the two controllers do not receive sufficient heat dissipation, and the internal chips and MOSFETs are not effectively cooled, leading to short-term controller failure and shortened lifespan.

[0006] Moreover, the separate design of the two controllers results in a non-compact structure for the entire chainsaw. Utility Model Content

[0007] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a controller assembly for a high-pressure brushless chainsaw that can effectively dissipate heat at the controller.

[0008] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0009] A controller assembly for a high-pressure brushless chainsaw includes a housing, a fan, a controller, and a drive unit for driving the chain. The housing is characterized by being hollow, with the controller, fan, and drive unit all located within it. The controller has two modules: module one and module two. Module one controls the power supply to the drive unit, and module two controls the start, stop, speed adjustment, and forward / reverse rotation of the drive unit. The housing has a through-hole air inlet and outlet. The fan is located within the housing between the air inlet and outlet. The controller assembly includes a mounting base and a mounting plate. The mounting base is fixed to the outside of the fan, and the mounting plate is detachably connected to the mounting base. Module one and module two are integrated and mounted on the mounting plate. A cooling channel is formed between the air inlet and outlet, and both modules one and module two are located within this cooling channel.

[0010] In the controller assembly of the aforementioned high-pressure brushless chainsaw, the fan includes a cylindrical body, which contains a motor and blades fixedly connected to the motor. A cover is fixedly connected to the end of the body and has several through holes.

[0011] In the controller assembly of the aforementioned high-pressure brushless chainsaw, the mounting base includes a cylindrical body and a connecting edge. The cylindrical body is cylindrical and open at one end. The connecting edge is fixed to the side of the open end of the cylindrical body. The outer side of the cylindrical body has a contact portion that matches the outer side of the main body. The connecting edge is fixed to the cover by fasteners. The contact portion of the cylindrical body contacts the outer side of the main body.

[0012] In the controller assembly of the aforementioned high-pressure brushless chainsaw, the connecting edge has several through-holes, the connecting edge contacts the cover surface, and the through-holes correspond one-to-one with the through holes.

[0013] In the controller assembly of the aforementioned high-pressure brushless chainsaw, the cylinder has a snap-fit ​​edge extending from its port to the bottom, and the edge of the insert plate is pressed tightly between the snap-fit ​​edge and one side of the cylinder.

[0014] In the controller assembly of the aforementioned high-pressure brushless chainsaw, there are two engagement edges, which are symmetrically located on the two inner sides of the cylinder.

[0015] In the controller assembly of the aforementioned high-pressure brushless chainsaw, the snap-fit ​​edge, connecting edge, and cylinder are all integral structures.

[0016] In the controller assembly of the aforementioned high-pressure brushless chainsaw, the outer side of the housing is open and a cover plate is connected to close the opening. The module one contains a capacitor, which is fixed to the substrate. The housing also contains a cylindrical positioning cylinder, in which the capacitor passes through the positioning cylinder. The substrate is pressed tightly between the cover plate and the positioning cylinder.

[0017] In the controller assembly of the aforementioned high-pressure brushless chainsaw, the cover plate has flexible positioning posts, and the aforementioned substrate is pressed tightly between the positioning posts and the positioning cylinder.

[0018] In the controller assembly of the aforementioned high-pressure brushless chainsaw, the air inlet is located on the cover plate.

[0019] Compared to existing technologies, the controller assembly of this high-pressure brushless chainsaw integrates both module one and module two of the controller onto a mounting plate. When the plate is connected to the mounting base, modules one and two are positioned close to the fan, allowing for effective heat dissipation during fan operation. This assembly not only improves the structural compactness of the high-pressure brushless chainsaw but also provides excellent heat dissipation for the controller. Therefore, the chainsaw has a longer service life and more stable operational quality.

[0020] Meanwhile, since both Module 1 and Module 2 are integrated and installed on the insert plate, the insert plate and the fixed base are easy to install and remove. Therefore, the entire chainsaw is not only simple to manufacture and process, but the controller part is also easy to install and remove, which is beneficial for subsequent maintenance.

Detailed Implementation

[0030] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0031] like Figure 1-7 As shown, the high-pressure brushless chainsaw includes a housing 11, a fan 2, a controller 3, and a drive unit 10 for driving the chain. The housing 1 is hollow inside, and the controller 3, fan, and drive unit are all located inside the housing 1. The controller 3 has two modules: module one and module two. Module one is used to control the power supply to the drive unit 10, and module two is used to control the start, stop, speed adjustment, and forward and reverse rotation of the drive unit 10. The housing 1 has a through air inlet 11 and an air outlet 12. The fan 2 is located inside the housing 1 between the air inlet 11 and the air outlet 12.

[0032] The controller assembly of this high-pressure brushless chainsaw includes a mounting base 4 and a plug plate 5. The mounting base 4 is fixed to the outside of the fan 2, and the plug plate 5 is detachably connected to the mounting base 4. Module 1 and Module 2 are both integrated and installed on the plug plate 5. A cooling channel is formed between the air inlet 11 and the air outlet 12, and both Module 1 and Module 2 are located within the cooling channel.

[0033] During the operation of the chainsaw, both the drive unit 10 and the fan 2 are powered on. The drive unit 10 drives the chain to move continuously, thereby achieving the cutting operation.

[0034] Of course, both Module 1 and Module 2 are in operation during the power-on process.

[0035] Module 1 is used to monitor, regulate, protect, and manage the power supply of the chainsaw. It can control voltage, current, power, and switch status according to load demand, system status, or preset strategies.

[0036] Module 2 enables the starting, stopping, speed adjustment, forward and reverse rotation, torque control, and precise positioning of the drive unit 10.

[0037] In other words, although Module 1 and Module 2 are integrated together, their functions are completely different.

[0038] When fan 2 is powered on, it creates a continuous and rapid airflow in the cooling channel. Since modules 1 and 2 of controller 3 are located in the cooling channel, they can be effectively cooled, ensuring that the chainsaw is in a stable operating state during operation.

[0039] The fan 2 includes a cylindrical body 21, inside which there is a motor 22 and blades 23 fixedly connected to the motor 22. A cover 24 is fixedly connected to the end of the body 21 and has several through holes 241.

[0040] Fan 2 is not the kind of device commonly seen in daily life; it is more appropriate to consider it a fan.

[0041] The main body 21 is equivalent to the housing of the fan, the motor 22 is fixedly connected inside the main body 21, and the blades 23 are fixedly connected to the shaft of the motor 22. During continuous operation, the fan can generate a rapid airflow in the cooling channel.

[0042] The fixing base 4 includes a cylindrical body 41 and a connecting edge 42. The cylindrical body 41 is cylindrical and open at one end. The connecting edge 42 is fixed to the side of the open end of the cylindrical body 41. The outer side of the cylindrical body 41 has a contact portion 411 that matches the outer side of the body 21. The connecting edge 42 is fixed to the cover 24 by fasteners. The contact portion 411 of the cylindrical body 41 contacts the outer side of the body 21.

[0043] The contact portion 411 of the mounting base 4 maintains surface contact with the outer side of the body 21, which improves the connection stability between the fan 2 and the mounting base 4. With the help of fasteners, the connecting edge 42 and the cover of the fan 2 are stably and securely connected.

[0044] The connecting edge 42 has several through holes 421, and the connecting edge 412 contacts the surface of the cover 24, with the through holes 421 corresponding to the through holes 241 one by one.

[0045] The through holes on the cover 24 are used for airflow. The clearance holes 421 and the through holes 241 are set one-to-one. This structure can avoid creating a large obstruction to the fast-flowing airflow in the cooling channel.

[0046] The cylinder 41 has a fastening edge 412 extending from its port to the bottom, and the edge of the insert plate 5 is pressed tightly between the fastening edge 512 and one side inside the cylinder 41.

[0047] There are two fastening edges 512, which are symmetrically located on the two inner sides of the cylinder 41.

[0048] Two fastening edges 412 are fastened to the two sides of the insert plate 5 respectively. This structure enables the insert plate 5 to be stably connected inside the cylinder 41.

[0049] Of course, under the action of the locking edge 412, the insert plate 5 and the cylinder 41 maintain a tight fit connection. After applying external force, the insert plate 5 can be easily removed, so the controller 3 is relatively easy to install and remove.

[0050] The fastening edge 412, the connecting edge 42, and the cylinder 41 are all integral structures.

[0051] The outer side of the housing 1 is open and a cover plate 6 is connected to the opening to close it. The module 1 has a capacitor 7, which is fixed to the substrate 8. The housing 1 also has a cylindrical positioning cylinder 9, in which the capacitor 7 passes. The substrate 8 is pressed tightly between the cover plate 6 and the positioning cylinder 9.

[0052] After the cover plate 6 is opened, the controller 3 and the housing 1 can be easily installed and removed.

[0053] Since module one is used for rectifying the input power supply, it contains a relatively large capacitor 7. The positioning cylinder 9 can position the capacitor 7, and the substrate 8 provides sufficient space for the capacitor 7 to be connected.

[0054] Since the substrate 8 is pressed tightly between the cover plate 6 and the positioning cylinder 9, the above structure can stably position the capacitor 7 in module one.

[0055] Since the positioning cylinder 9 is also located in the cooling channel, the capacitor 7 can also receive stable air cooling.

[0056] The cover plate 6 has a flexible positioning post 61, and the base plate 8 is pressed tightly between the positioning post 61 and the positioning cylinder 9.

[0057] In this embodiment, the positioning post 61 is made of rubber. The flexible positioning post 61 not only prevents the substrate 8 from being rigidly squeezed, but also eliminates the gap between the substrate 8 and the corresponding connection.

[0058] The air inlet 11 is located on the cover plate 6.

[0059] This structure reduces the number of holes in the housing 1 and appropriately increases its strength. Furthermore, the cover plate 6 faces the fan 2 directly, ensuring that the airflow within the cooling channel is linear, effectively improving the air-cooling effect.

[0060] The controller assembly of this high-pressure brushless chainsaw integrates both module one and module two onto a mounting plate. When the plate is connected to the mounting base, modules one and two are positioned close to the fan, allowing for effective heat dissipation during fan operation. This assembly not only improves the structural compactness of the high-pressure brushless chainsaw but also provides excellent heat dissipation for the controller. Therefore, the chainsaw has a relatively long service life and stable operational quality.

[0061] Meanwhile, since both Module 1 and Module 2 are integrated and installed on the insert plate, the insert plate and the fixed base are easy to install and remove. Therefore, the entire chainsaw is not only simple to manufacture and process, but the controller part is also easy to install and remove, which is beneficial for subsequent maintenance.

[0062] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0063] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
