Description

Technical Field

[0001] The utility model relates to the technical field of woodworking electric saws, in particular to a connecting component for a woodworking electric saw host and a controller. Background Art

[0002] Generally, woodworking electric saws use brushed motors, which have the characteristics of large torque but also large noise. Therefore, when the torque is sufficient, brushless motors are also used in the woodworking electric saw industry. Since brushless motors need to be used with corresponding controllers, in the prior art, the brushless motor host and controller are separate, and are respectively on the electric saw substrate, which has a complex structure, increases the size of the motor, and is also cumbersome to install and maintain. Furthermore, although the controller itself has a finned heat sink, it can only dissipate heat statically at a distance from the electric saw host, and the heat dissipation effect is poor. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of existing products and provide a connecting assembly for a woodworking electric saw host and a controller, so as to solve the connection and assembly problem of a brushless electric saw motor host and a controller, and at the same time improve the heat dissipation effect of the controller.

[0004] The technical solution adopted by the utility model is: a connecting component for a woodworking electric saw mainframe and a controller, the connecting component includes a first connecting member and a second connecting member, the first connecting member has a first surface that can be connected to a motor main body shell, a first connecting hole connected to the motor main body shell is provided on the first surface, and the two sides of the first surface also have a second surface and a third surface that are perpendicular to the first surface, and the second surface and the third surface are also perpendicular to the surface of the motor main body shell; the rear end of the first surface also has a fourth surface and a fifth surface that extend vertically in sequence, and a hollow first ventilation hole is provided on the fourth surface; the second connecting member has a sixth surface that is in contact with and connected to the first surface of the first connecting member, and a seventh surface that is perpendicular to the sixth surface, and a second connecting hole corresponding to the position of the first connecting hole is provided on the sixth surface; the seventh surface has a third connecting hole that can be connected to a heat sink of the controller.

[0005] Preferably, the contact end surfaces of the second surface and the third surface of the first connecting member with the motor main body housing have tip portions that abut against the motor main body housing.

[0006] Preferably, hollow second ventilation holes are respectively formed on the first surface of the first connecting member and the sixth surface of the second connecting member.

[0007] Preferably, a filter sponge is arranged at a spacing portion between the inner sides of the fourth surface and the fifth surface of the first connecting member and the rear end surface of the motor body.

[0008] The second connecting member also has an eighth surface and a ninth surface at both ends thereof, the eighth surface and the ninth surface being perpendicular to the sixth surface and the seventh surface.

[0009] By adopting the connection assembly of the utility model, namely the first connection piece and the second connection piece, the motor body and the controller can be connected as one, which brings convenience to use and carrying. At the same time, since the heat sink of the controller is in direct contact with the second connection piece, its heat can be conducted to the second connection piece and the first connection piece made of metal material for heat dissipation. Moreover, since the brushless motor itself has blades at the front and rear ends to generate wind heat dissipation, the heat dissipation effect of the controller is greatly improved, which is beneficial to the stable operation of the controller and the extension of its service life.

[0014] The utility model is further described below in conjunction with specific embodiments and drawings.

[0015] like Figure 1-Figure 8As shown, the present embodiment describes a connection assembly for a woodworking electric saw host and a controller, the connection assembly comprising a first connection member 1 and a second connection member 2, the first connection member 1 having a first surface 11 connectable to the outer shell of a motor body 3, the first surface 11 being provided with a first connection hole 111 connected to the outer shell of the motor body 3, the first surface 11 having a second surface 12 and a third surface 13 perpendicular to the first surface 11 on both sides, and the second surface 12 and the third surface 13 being perpendicular to the outer shell surface of the motor body 3; the rear end of the first surface 11 also having a fourth surface 14 and a fifth surface 15 extending perpendicularly in sequence, and a spacer 100 being provided between the fourth surface 14 and the rear end surface of the motor body 3, the fifth surface 15 being perpendicular to the rear end surface of the outer shell of the motor body 3, and a hollow first ventilation hole 141 being provided on the fourth surface 14; The second connecting member 2 has a sixth surface 21 that is in contact with and connected to the first surface 11 of the first connecting member 1, and a seventh surface 22 that is perpendicular to the sixth surface 21. The sixth surface 21 is provided with a second connecting hole 211 corresponding to the position of the first connecting hole 111, that is, the first connecting member 1 and the second connecting member 2 are fixedly connected to the surface of the outer shell of the motor body 3 by the same set of screws at the same time, and the outer shell surface of the motor body 3 has a connecting boss 31. The second surface 12 and the third surface 13 of the first connecting member 1 are perpendicular in the direction toward the motor body, and the seventh surface 22 of the second connecting member 2 extends vertically in the direction away from the motor body 3; the seventh surface 23 is provided with a third connecting hole 231 that can be connected to the heat sink 41 of the controller 4; that is, the controller 3 is fixedly connected to the second connecting member 2 with screws through the screw holes provided on the heat sink 41 and the third connecting hole 231.

[0016] Preferably, the contact end surfaces of the second surface 12 and the third surface 13 of the first connecting member 1 and the outer shell of the motor body 3 have a tip portion 121 that contacts the outer shell of the motor body. The tip portion 121 can achieve the positioning effect of the second surface 12 and the third surface 13 and the groove on the outer shell of the motor body 3, and at the same time can reduce the contact area between the outer shell of the motor body 3 and the first connecting member 1, reduce the heat transfer of the outer shell of the motor body 3 to the first connecting member 1, and form a hollow for air circulation and heat dissipation;

[0017] Preferably, hollow second ventilation holes 112 (212) are respectively opened on the first surface 11 of the first connecting member 1 and the sixth surface 21 of the second connecting member 2, which further facilitates air circulation around the motor body 3 and the controller 4 and improves the heat dissipation effect.

[0019] The two ends of the second connecting member 2 are also provided with an eighth surface 23 and a ninth surface 24 which are perpendicular to the sixth surface 21 and the seventh surface 22 , so as to provide a better covering and protecting effect for the controller 4 and also increase the heat dissipation area.

[0020] To sum up, by adopting the connection assembly of the utility model, namely the first connection member 1 and the second connection member 2, the motor body and the controller can be connected as one, which brings convenience to use and carrying. At the same time, since the heat sink of the controller is in direct contact with the second connection member, its heat can be conducted to the second connection member and the first connection member made of metal material for heat dissipation, and since the brushless motor itself has blades at the front and rear ends to generate wind heat dissipation, the heat dissipation effect of the controller is greatly improved, which is beneficial to the stable operation of the controller and the extension of its service life.
