Detailed Description

The motor device of the present invention is explained below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments disclosed are merely illustrative of specific ways to make and use the utility model, and do not delimit the scope of the utility model.

Fig. 1 is a schematic view showing a motor apparatus M according to an embodiment of the present invention, and fig. 2 is a sectional view taken along a-a direction in fig. 1. The motor device M can be installed in an electronic apparatus to drive components in the electronic apparatus to rotate or move.

As shown in fig. 1 and 2, the motor apparatus M mainly includes a motor assembly 100, an encoder assembly 200, a power adapter plate 300, a plurality of press-contact terminals 400, and a connector 500.

The motor assembly 100 includes a motor frame 110, a stator 120, a rotor 130, and a plurality of bearings 140. The motor frame 110 includes a front cover 111, a separating frame 112, and a rear cover 113, wherein the separating frame 112 is disposed between the front cover 111 and the rear cover 113, and can be connected to the front cover 111 and the rear cover 113 to form an inner space R, and the stator 120, the rotor 130, and the bearing 140 can be accommodated in the inner space R.

The stator 120 may include a plurality of power conductors 121 (e.g., coils or metal sheets) and a stator circuit board 122, and the power conductors 121 are electrically connected to the stator circuit board 122, respectively. The rotor 130 may include a shaft 131 and a plurality of magnets 132 connected to the shaft 131. The power conductor 121 corresponds to the magnet 132, and surrounds the magnet 132 and the rotating shaft 131. The rotating shaft 131 is rotatable with respect to the motor housing 110 and the stator 120 by an electromagnetic action between the power conductor 121 and the magnet 132. Specifically, when a current flows through the power conductor 121, an electromagnetic driving force is generated and applied to the magnet 132, so as to drive the rotating shaft 131 to rotate relative to the motor housing 110 and the stator 120.

The bearing 140 is disposed between and connected to the motor housing 110 and the rotating shaft 131. The bearing 140 can effectively position the rotating shaft 131, and the rotating shaft 131 can rotate relative to the motor frame 110 and the stator 120 more smoothly.

The encoder assembly 200 includes an encoder housing 210 and an encoder 220. The encoder frame 210 is mechanically connected to the rear end cap 113 of the motor frame 110, so that the encoder frame 210 and the rear end cap 113 together form a receiving space S. The encoder 220 is accommodated in the accommodating space S.

Fig. 3A is a partial schematic view showing the motor device M with the encoder housing 210 removed, fig. 3B is a schematic view showing the crimp terminal 400 and the support bracket 410, and fig. 3C is a schematic view showing the power adapter 300. As shown in fig. 2 to fig. 3C, the power adapter 300 is disposed opposite to the rear end cap 113 of the motor frame 110 and is accommodated in the accommodating space S. In some embodiments, the power adapter plate 300 is fixed to the rear end cap 113 by at least one bolt F; in other embodiments, the power adapter plate 300 does not need to be fixed to the rear end cover 113, but the press contact terminal 400 and the support frame 410 are fixed to the power adapter plate 300 by engaging at least one locking member 411 formed on the support frame 410 corresponding to the press contact terminal 400 with a locking hole 303 correspondingly disposed on the power adapter plate 300, but the utility model is not limited thereto. The press-fit terminal 400 is fixed to the stator 120, and has one end electrically connected to the stator circuit board 122. Specifically, the other end of the press-fit terminal 400 is fixed to the power adapter 300 by press-fitting and electrically connected to the power adapter 300. That is, the press-fit terminal 400 electrically connects the stator circuit board 122 and the power adapter plate 300, and completes the electrical connection between the power conductor 121 and the power adapter plate 300.

In the present embodiment, the power adapter plate 300 has a first surface 301 and a second surface 302 opposite to each other, and the first surface 301 faces the stator 120. After the crimp terminal 400 is fixed to the power adapter plate 300 by crimping, the crimp terminal 400 passes through the power adapter plate 300, so that the end portion protrudes from the second surface 302 of the power adapter plate 300.

Referring to fig. 1 to 4, in the present embodiment, the connector 500 is disposed on a side edge 113A of the rear end cover 113, and the power adapter 300 and the encoder 220 are electrically connected to the output end 510 of the connector 500 through a power wire W1 and a signal wire W2, respectively. It should be noted that, since the power wire W1 and the signal wire W2 only pass through the accommodating space S, the user does not need to additionally install a wire connected to an external device (e.g., a power supply) on the motor assembly 100, thereby improving the assembly efficiency of the motor device M.

Since the connector 500 is electrically connected to the power adapter plate 300 through the power wire W1, and the power wire W1 and the crimp terminal 400 are electrically connected to each other through the power adapter plate 300, when an external device is connected to the connector 500, power or signals provided by the external device can be sequentially supplied to the power conductor 121 through the connector 500, the power wire W1, the power adapter plate 300, the crimp terminal 400, and the stator circuit board 122. Moreover, since the connector 500 is electrically connected to the encoder 220 via the signal wire W2, when an external device is connected to the connector 500, power or signals provided by the external device can be simultaneously supplied to the encoder 220.

Referring to fig. 5 and 6A, according to the aforementioned structure of the motor device M, the rear cover 113, the power adapter plate 300, the connector 500, the power wire W1, and the signal wire W2 may be pre-assembled to form a first integrated member C1, and the front cover 111, the separation frame 112, the stator 120, the rotor 130, and the press-contact terminal 400 may be pre-assembled to form a second integrated member C2. Therefore, when assembling the motor apparatus M, the user only needs to approach the assembled first integration member C1 to the second integration member C2 to connect the crimp terminal 400 and the power adaptor plate 300 by crimping, and the assembly of the motor apparatus M can be completed. Therefore, the assembly efficiency of the motor device M can be greatly improved, partial parts of the motor device M can be replaced or maintained conveniently, and the situation that the whole motor device fails due to the fact that a lead is broken due to pulling when the motor device is disassembled is avoided.

Referring to fig. 6B, in another embodiment of the present invention, the separation frame 112, the rear cover 113, the power adapter 300, the connector 500, the power wire W1, and the signal wire W2 may be pre-assembled to form a first integrated component C1', wherein the separation frame 112 and the rear cover 113 are integrally formed. The front cover 111, the stator 120, the rotor 130, and the crimp terminal 400 may be pre-assembled and formed into a second integrated member C2'. In assembling the motor apparatus M, the user only needs to approach the assembled first integration member C1 'toward the second integration member C2' to connect the crimp terminal 400 and the power adaptor plate 300 in a crimping manner, so as to complete the assembly of the motor apparatus M. After the first integration member C1(C1 ') and the second integration member C2 (C2') are assembled, the encoder 220 of the encoder assembly 200 can be assembled in the reserved space of the rear end cap 113, and finally the encoder frame 210 is assembled to complete the assembly of the encoder 200, wherein the encoder frame 210 covers at least one side of the rear end cap 113.

Referring to fig. 7, a plurality of electrical pins P1, P2 are disposed on the input terminal 520 of the connector 500 connected to the external device, and the electrical pins P1, P2 are arranged according to a pin definition (pin definition). The input terminal 520 is opposite to the output terminal 510. Specifically, the pin definition is that a plurality of electrical pins P1 corresponding to the power wires W1 are arranged and disposed in a power region R1, a plurality of electrical pins P2 corresponding to the signal wires W2 are arranged and disposed in a signal region R2, and the power region R1 and the signal region R2 are separated from each other. Among the plurality of electrical pins P1 corresponding to the power wire W1 in the power region R1, one or more electrical pins P11 adjacent to the signal region R2 are grounded, and among the plurality of electrical pins P2 corresponding to the signal wire W2, one or more electrical pins P21 adjacent to the power wire W1 are grounded. Thus, the interference between the power wire W1 and the signal wire W2 can be reduced.

In the present embodiment, the connector 500 may include a spacer 530 disposed between the power region R1 and the signal region R2, and the spacer 530 may have a shielding material (e.g., nickel plating, but not limited thereto) to further reduce interference between the power wire W1 and the signal wire W2.

Referring to fig. 8 and 9, in another embodiment of the present invention, a motor device M' mainly includes a motor assembly 100, an encoder assembly 200, a power adapter plate 300, a plurality of press-connection terminals 400, a connector 500, a brake assembly 600, and a lead frame 700.

The stator 120 may include a plurality of power conductors 121 (e.g., coils or metal sheets), and the rotor 130 may include a rotating shaft 131 and a plurality of magnets 132 coupled to the rotating shaft 131. The power conductor 121 corresponds to the magnet 132, and surrounds the magnet 132 and the rotating shaft 131. The rotating shaft 131 is rotatable with respect to the motor housing 110 and the stator 120 by an electromagnetic action between the power conductor 121 and the magnet 132. Specifically, when a current flows through the power conductor 121, an electromagnetic driving force is generated and applied to the magnet 132, so as to drive the rotating shaft 131 to rotate relative to the motor housing 110 and the stator 120.

The bearing 140 is disposed between and connected to the motor housing 110 and the rotating shaft 131. The bearing 140 can effectively position the rotating shaft 131, and the rotating shaft 131 can rotate relative to the motor frame 110 more smoothly.

Referring to fig. 9 and 10, the brake assembly 600 includes a brake frame 610, a brake mechanism 620, and a brake adapter plate 630. The brake frame 610 is connected to the motor frame 110, and the inner space of the brake frame 610 can be divided into a brake accommodating space S1 and an encoder accommodating space S2 by the partition 611. The brake mechanism 620 is accommodated in the brake accommodating space S1 and is mechanically connected to the shaft 131. The brake mechanism 620 provides friction to the shaft 131, so that the shaft 131 can be changed from the rotating state to the stopping state when necessary. For example, the braking mechanism 620 may include, but is not limited to, a brake drum, brake shoes, brake discs, and/or brake calipers.

The lead frame 700 is disposed on the braking frame 610 and located between the braking mechanism 620 and the stator 120. The brake adapter plate 630 is fixed on the end surface 710 of the lead frame 700 facing the stator 120 and electrically connected to the braking mechanism 620.

The encoder assembly 200 includes an encoder housing 210 and an encoder 220. The encoder frame 210 is mechanically connected to the brake frame 610, and the encoder 220 is accommodated in the encoder accommodating space S2.

Like the brake adapter plate 630, the power adapter plate 300 is also fixed to the end surface 710 of the lead frame 700. However, the power adapter plate 300 and the brake adapter plate 630 are not in contact with each other, but are separated. The crimp terminal 400 is fixed to the stator 120 and electrically connected to the power conductor 121. The press-fit terminal 400 is fixed to the power adapter plate 300 by press-fitting and electrically connected to the power adapter plate 300. In some embodiments, the power adapter plate 300 and the brake adapter plate 630 can be integrated into a single plate, but are disposed at different positions of the plate.

In the present embodiment, the power adapter plate 300 has a first surface 301 and a second surface 302 opposite to each other, and the first surface 301 faces the stator 120. After the crimp terminal 400 is fixed to the power adapter plate 300 by crimping, the crimp terminal 400 passes through the power adapter plate 300, and the end of the crimp terminal protrudes from the second surface 302 of the power adapter plate 300.

Referring to fig. 9 to 12, in the present embodiment, the connector 500 is disposed on a side edge 612 of the brake frame 610. The power adapter board 300, the encoder 220, and the brake adapter board 630 are connected to the output end 510 of the connector 500 via a power wire W1, a signal wire W2, and a brake wire W3, respectively. It should be noted that, since the power wires W1 and the brake wires W3 only pass through the brake accommodating space S1 and the signal wires W2 only pass through the encoder accommodating space S2, the user does not need to additionally provide wires for connecting the motor assembly 100 with an external device (e.g., a power supply), thereby improving the assembly efficiency of the motor device M'.

Since the connector 500 is electrically connected to the power adapter plate 300 through the power wire W1, and the power wire W1 and the crimp terminal 400 are electrically connected to each other through the power adapter plate 300, when an external device is connected to the connector 500, power or signals provided by the external device can be sequentially supplied to the power conductor 121 through the connector 500, the power wire W1, the power adapter plate 300, the crimp terminal 400, and the stator circuit board 122. Next, since the connector 500 is electrically connected to the encoder 220 through the signal wire W2, when an external device is connected to the connector 500, power or signals provided by the external device can be simultaneously supplied to the encoder 220. Furthermore, since connector 500 is electrically connected to brake mechanism 620 via brake wires W3 and brake adapter plate 630, when an external device is connected to connector 500, power or signals provided by the external device can be supplied to brake mechanism 620 at the same time.

Referring to fig. 13, according to the aforementioned structure of the motor device M', the brake assembly 600, the lead frame 700, the power adapter plate 300, the connector 500, the power wire W1, the signal wire W2, and the brake wire W3 may form a first integrated member C1 ", and the motor assembly 100 and the crimp terminal 400 may form a second integrated member C2". Therefore, when assembling the motor apparatus M ', the user only needs to approach the assembled first integration member C1 "toward the second integration member C2" to connect the crimp terminal 400 and the power adapter plate 300 by crimping, so as to complete the assembly of the motor apparatus M'. Therefore, the assembly efficiency of the motor device M 'can be greatly improved, partial parts of the motor device M' can be replaced or maintained conveniently, and the situation that the whole motor device fails due to the fact that a lead is broken due to pulling when the motor device is disassembled is avoided. After the first integrated member C1 ″ and the second integrated member C2 ″ are assembled, the encoder 220 of the encoder assembly 200 can be assembled in the encoder accommodating space S2 defined by the brake frame 610, and finally the encoder frame 210 is assembled to complete the assembly of the encoder 200, wherein the encoder frame 210 covers at least one side of the encoder accommodating space S2.

Referring to fig. 14, a plurality of electrical pins P1, P2, P3 are disposed on the input terminal 520 of the connector 500 for connecting to an external device, and the electrical pins P1, P2, P3 are arranged according to a pin definition (pin definition). The input terminal 520 is opposite to the output terminal 510. Specifically, the pin definition includes disposing a plurality of electrical pins P1 corresponding to the power wires W1 in a power region R1, disposing a plurality of electrical pins P2 corresponding to the signal wires W2 in a signal region R2, disposing a plurality of electrical pins P3 corresponding to the brake wires W3 in a brake region R3, and separating the power region R1, the signal region R2 and the brake region R3 from each other. Among the plurality of electrical pins P1 corresponding to the power wire W1 in the power region R1, one or more electrical pins P11 adjacent to the signal region R2 are grounded, and among the plurality of electrical pins P2 corresponding to the signal wire W2 in the signal region R2, one or more electrical pins P21 adjacent to the power wire W1 in the power region R1 are grounded. In the present embodiment, at least a portion of the power region R1 is disposed between the signal region R2 and the braking region R3, and one or more electrical pins P11 disposed between the signal region R2 and the braking region R3 are grounded. Therefore, the interference among the power wire W1, the brake wire W3 and the signal wire W2 can be reduced.

In this embodiment, connector 500 may include a spacer 530 disposed between power region R1 and signal region R2, and spacer 530 may include shielding material (e.g., but not limited to nickel plating) to further reduce interference between power wire W1, brake wire W3 and signal wire W2.
