Description

Technical Field

[0001] This utility model relates to the field of curtain machine technology, and in particular to a conductive structure for a curtain machine. Background Technology

[0002] Electric curtain motors are devices that enable curtains to open and close automatically. Currently, most electric curtain motors on the market use a belt (synchronous belt) to control the opening and closing. The belt is driven by a motor mounted on the curtain track. The motor drives the belt to rotate, and the rotation of the belt opens and closes the curtains.

[0003] A few electric curtain motors employ a transmission method disclosed in CN201263033Y. This method involves two conductive strips and a rack within the curtain track, along with a movable body. This movable body contains brushes, gears, and a motor to drive the gears. The brushes conduct electricity in contact with the conductive strips, and the gears on the movable body mesh with the rack on the curtain track. When the motor drives the gears, the gears move the movable body within the curtain track. By applying current of different polarities to the two conductive strips, the motor's forward and reverse rotation can be controlled, allowing the curtains to open and close. However, this transmission method has some drawbacks, resulting in significantly lower heat generation compared to belt-driven curtain mechanisms. These drawbacks include: unreliable conductivity between the movable body and the conductive strips; uneven conductive strips or large gaps in the assembly structure can lead to poor contact, unstable conductivity, and uneven movement of the movable body; furthermore, repeated friction on the conductive strips causes wear and reduces their lifespan.

[0047] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0048] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0051] like Figure 1 As shown in the figure, an embodiment of the present invention illustrates a conductive structure for a curtain machine, including a conductive strip 200 and a movable body 1. The conductive strip 200 is arranged along the length direction of the curtain rail 100; the movable body 1 is movably arranged along the length direction of the curtain rail 100, and the movable body 1 is provided with a conductive contact 11, which is configured to abut against the conductive strip 200 under the action of elastic force.

[0052] To facilitate understanding of its operation, the transmission structure of this curtain machine is also described below, such as... Figure 1 and Figure 2 As shown, the curtain track 100 is also provided with a transmission strip 300, which is arranged along the length of the curtain track 100; there are two conductive strips 200, which are configured to carry electricity of different polarities; the moving body 1 is also provided with a transmission wheel 16 and a motor 17 for driving the transmission wheel 16 to rotate; there are two conductive contacts 11, which are electrically connected to the motor 17, and the two conductive contacts 11 correspond one-to-one with the two conductive strips 200; the transmission wheel 16 is in transmission cooperation with the transmission strip 300, and when the transmission wheel 16 rotates, the transmission wheel 16 moves along the length of the transmission strip 300.

[0053] The transmission wheel 16 can be a gear, and the transmission bar 300 can be a rack; the transmission wheel 16 can also be a synchronous pulley, and the transmission bar 300 can be a synchronous belt; or the transmission wheel 16 and the transmission bar 300 can be other structures, as long as they can enable the transmission wheel 16 to move along the length of the transmission bar 300 when the transmission wheel 16 rotates.

[0054] When the conductive contact 11 contacts the conductive strip 200, the conductive contact 11 can conduct electricity from the conductive strip 200 to the motor 17. When the two conductive strips 200 are supplied with electricity of different polarities, for example, one conductive strip 200 is positive and the other is negative, the motor 17 drives the transmission wheel 16 to rotate forward. If the polarities of the two conductive strips 200 are reversed, the motor 17 drives the transmission wheel 16 to rotate in reverse. In this way, the moving body 1 can reciprocate within the curtain track.

[0055] The conductive contact 11 is constantly pressed against the conductive strip 200 by the elastic force. Regardless of whether the conductive strip 200 is uneven, the assembly structure has large gaps, or is affected by external vibration, reliable contact and stable conductivity between the conductive contact 11 and the conductive strip 200 can be ensured.

[0056] The conductive contact 11 can be driven by an external elastic element 12 or by its own elastic force, thereby abutting against the conductive strip 200.

[0057] The conductive strip 200 can be made of metal, such as copper; of course, it is not limited to this and other conductive materials can be selected as needed.

[0058] Optionally, a protruding arc-shaped contact portion 111 is formed on the conductive contact 11, and the arc-shaped contact portion 111 contacts the conductive strip 200 to conduct electricity. In this way, the contact area between the conductive contact 11 and the conductive strip 200 can be reduced, the wear rate of the conductive strip 200 can be reduced, and the service life can be improved.

[0059] In addition, the conductive contact 11 and the conductive strip 200 can be configured as a rolling contact connection, so that the conductive contact 11 and the conductive strip 200 are in rolling friction, thereby reducing the wear rate of the conductive strip 200.

[0060] The following examples further illustrate the following:

[0061] Example 1

[0062] like Figure 3 and Figure 4 As shown, in this embodiment, the movable body 1 is provided with an elastic element 12, which applies an elastic preload to the conductive contact 11 so that the conductive contact 11 abuts against the conductive strip 200.

[0063] In this embodiment, the elastic element 12 is a spring, but it does not mean that only springs can be used. The elastic element 12 can also be a sheet, a rubber pad, a tension spring, or other structures.

[0064] In this embodiment, the conductive contact 11 is provided with more than one arc-shaped contact portion 111, specifically two, so that it can form multi-point contact with the conductive strip 200, thereby improving stability, while also avoiding large-area surface contact with the conductive strip 200 to prevent excessive friction.

[0065] In this embodiment, a circuit board (not shown in the figure) is provided inside the moving body 1. The circuit board is electrically connected to the motor 17, and the conductive contact 11 is connected to the circuit board through a wire (not shown in the figure).

[0066] Example 2

[0067] like Figure 5-8As shown, the moving body 1 is provided with a limiting member 13, and the limiting member 13 is provided with a limiting channel 131 for the conductive contact member 11 to slide. The elastic member 12 is disposed in the limiting channel 131. The limiting member 13 is made of conductive material, and the limiting member 13 contacts the conductive contact member 11 and forms an electrical connection.

[0068] In this embodiment, the limiting channel 131 is used to provide guidance for the conductive contact 11, so that the conductive contact 11 can only move in a specified direction, making the conductive contact 11 more stable when moving.

[0069] In this embodiment, the conductive contact 11 is floating, while the limiting member 13 is fixed, such as... Figure 8 As shown, the lower end of the limiting member 13 can be connected to the circuit board via a wire (not shown), and the circuit board is electrically connected to the motor 17; thereby realizing the electrical connection between the conductive contact 11 and the motor 17; thus, the wiring and power supply are carried out through the fixed-position limiting member 13, making the wiring structure more stable.

[0070] In this embodiment, the conductive contact 11 is columnar with an arc-shaped contact portion 111 at its top. In addition, to prevent the elastic member 12 from completely pushing the conductive contact 11 out of the limiting channel 131, the opening of the limiting channel 131 (not marked in the figure) can be set with a small diameter, and a limiting block (not marked in the figure) with a larger width can be provided on the conductive contact 11. The limiting block cannot disengage from the opening of the limiting channel 131.

[0071] Example 3

[0072] like Figure 9 and Figure 10 As shown, the conductive contact 11 is elastic and abuts against the conductive strip 200 under its own elastic force.

[0073] In this embodiment, the conductive contact 11 is formed by elastically bending a metal strip, and it has elasticity and conductivity. The conductive contact can be a circular metal strip, a square metal strip, a thin sheet-shaped metal strip, etc.

[0074] In this embodiment, the conductive contact 11 is bent to form an arc-shaped contact portion 111.

[0075] Example 4

[0076] like Figure 11-15 As shown, the conductive contact 11 is a wheel, and the conductive contact 11 and the conductive strip 200 are connected by a rolling contact. When the moving body 1 moves, the conductive contact 11 rolls along the conductive strip 200, the friction force on the conductive strip 200 is small, and the wear rate is reduced.

[0077] In this embodiment, the outer peripheral wall of the wheel body forms an arc-shaped contact portion 111.

[0078] In this embodiment, to facilitate the installation of the conductive contact 11, the movable body 1 is provided with a mounting base 14, the conductive contact 11 is rotatably mounted on the mounting base 14, and the elastic element 12 acts on the mounting base 14; wherein, the elastic element 12 indirectly acts on the conductive contact 11.

[0079] To facilitate a stable electrical connection between the rotatable conductive contact 11 and the motor 17, such as Figure 13 and Figure 14 As shown, the conductive contact 11 is provided with a rotating shaft 112, and the mounting base 14 is provided with a conductive support 15. The drive shaft of the conductive contact 11 is rotatably connected to the conductive support 15, and the conductive contact 11 and the conductive support 15 form an electrical connection.

[0080] The conductive support 15 includes two elastic clamping arms 151, with the rotating shaft 112 clamped between them. The two elastic clamping arms 151 can clamp the rotating shaft 112, but the rotating shaft 112 can still rotate; in this embodiment, as... Figure 15 As shown, the lower end of the conductive support 15 can be connected to a circuit board (not marked in the figure) via wires, and the circuit board wires are connected to the motor 17.

[0081] To improve the stability of the rotating shaft 112 mounted on the two elastic clamping arms 151, such as Figure 14 As shown, the inner sides of the two elastic clamping arms 151 are recessed with slots 152, and the rotating shaft 112 is disposed within the slots 152 of the two elastic clamping arms 151. The slots 152 can be arc-shaped, V-shaped, or other structures. This allows the rotating shaft 112 to rotate stably on the two elastic clamping arms 151, while also facilitating assembly and disassembly.

[0082] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0083] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
