Description

Technical Field

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

[0002] An electric curtain motor is a device that enables curtains to open and close automatically. Currently, a few electric curtain motors on the market use a transmission method disclosed in CN201263033Y. This method involves installing two conductive strips and a rack within the curtain track, and arranging a movable body within the track. The movable body is equipped with brushes, gears, and a motor that drives 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 to rotate, the gears move the movable body within the curtain track. By applying current of different polarities to the two conductive strips, the forward and reverse rotation of the motor can be controlled, and the movement of the movable body enables the curtains to open and close.

[0003] Currently, most curtain machines using the aforementioned transmission methods employ a single-track structure. However, to meet the needs of convenient logistics and transportation, and the ability to flexibly assemble guide rails of different lengths, curtain machines need to be designed with a segmented, spliced ​​structure. But how to achieve an effective and stable electrical connection between the multiple conductive strips between the segments is a challenge that needs to be overcome. Utility Model Content

[0004] In view of this, the present invention proposes a conductive strip splicing structure for a curtain machine, the purpose of which is to achieve reliable conductivity during the splicing of the curtain machine.

[0005] The solution provided by this utility model includes:

[0006] A conductive strip connection structure for a curtain machine includes:

[0007] A guide rail section, wherein a conductive strip is provided within the guide rail section;

[0008] A conductive connector is disposed between two guide rail segments. A portion of the conductive connector is pressed and engaged with a conductive strip in one guide rail segment, and another portion of the conductive connector is pressed and engaged with a conductive strip in the other guide rail segment, so as to achieve an electrical conductive connection between the conductive strips in the two guide rail segments.

[0009] As a further optional solution, a first crimping member and a second crimping member are also included;

[0010] A portion of the conductive connector is pressed against a conductive strip within a guide rail segment by the first crimping member, and another portion of the conductive connector is pressed against a conductive strip within another guide rail segment by the second crimping member.

[0011] As a further optional solution, a mounting base is also included, which is disposed between the two guide rail sections;

[0012] The conductive connector is a long strip-shaped metal piece, with both ends of the conductive connector connected to the mounting base, and the conductive connector located between the mounting base and the conductive strip.

[0013] Both the first and second crimping members are screws, which are threaded onto the mounting base. One end of the screw presses against the conductive connector so that the conductive connector is pressed tightly against the conductive strip.

[0014] As a further alternative, the mounting base is disposed inside the guide rail section, and the mounting base is slidably disposed along the length direction of the guide rail section.

[0015] As a further optional solution, the mounting base is disposed outside the guide rail section, and the outer side of the guide rail section is provided with a clearance hole to allow the conductive strip section to contact the outside. The conductive connector is disposed in the clearance hole to achieve contact with the conductive strip section.

[0016] As a further optional solution, a channel is formed inside the mounting base, and the guide rail section is slidably disposed in the channel. The mounting base is provided with a locking hole, and a locking screw is threaded into the locking hole. The end of the locking screw abuts against the outside of the guide rail section to achieve relative fixation between the mounting base and the guide rail section.

[0017] As a further optional solution, the conductive connector is a long strip-shaped metal piece, and the first pressing member and the second pressing member are elastic rubber blocks fixed at both ends of the conductive connector, respectively.

[0018] The end of the guide rail segment is provided with a socket, and the conductive strip segment is located on the side of the socket; the first crimping member and the second crimping member are respectively inserted into the sockets of the two guide rail segments, and the width of the first crimping member and the second crimping member in their natural state is greater than the width of the socket.

[0019] As a further optional solution, the conductive connector has elastic expansion and contraction portions at both ends, and the end of the guide rail section is provided with a socket for the elastic expansion and contraction portion to be inserted. The conductive strip is located on the side of the socket. The width of the elastic expansion and contraction portion in its natural state is greater than the width of the socket. After the elastic expansion and contraction portion is inserted into the socket, one side of the elastic expansion and contraction portion is pressed against the conductive strip.

[0020] As a further optional solution, the conductive connector is a long strip-shaped metal piece. The conductive connector includes a conductive connector body, and the two ends of the conductive connector body are bent to form a first bent segment and a second bent segment, respectively. An expansion and contraction space is formed between the first bent segment and the conductive connector body, and between the second bent segment and the conductive connector body.

[0021] As a further optional solution, the conductive strip is a long, flat copper strip.

[0022] Compared with the prior art, the conductive strip splicing structure of the curtain machine in this application has at least the following advantages:

[0023] In this conductive connector structure, by forming a compression fit between the conductive connector and the conductive strip, the friction between the conductive connector and the conductive strip is increased, so that the conductive connector and the conductive strip are effectively connected and not easily separated, ensuring that the two conductive strips can stably achieve electrical conduction.

[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] This utility model discloses a conductive strip connection structure for a curtain machine, including a guide rail section 1 and a conductive connector 3. The guide rail section 1 is provided with a conductive strip section 2. The conductive connector 3 is disposed between two guide rail sections 1. A part of the conductive connector 3 is pressed and engaged with the conductive strip section 2 in one guide rail section 1, and the other part of the conductive connector 3 is pressed and engaged with the conductive strip section 2 in the other guide rail section 1, so as to realize the electrical conduction connection between the conductive strip sections 2 in the two guide rail sections 1.

[0052] Among them, multiple guide rail segments 1 are connected to form a complete curtain machine guide rail, and multiple conductive strip segments 2 are connected to form a complete conductive strip 2; the present invention mainly solves the problem of conductivity between the connecting conductive strip segments 2.

[0053] Specifically, by forming a compression fit between the conductive connector 3 and the conductive strip 2, the friction between the conductive connector 3 and the conductive strip 2 is increased, so that the conductive connector 3 and the conductive strip 2 are effectively connected and not easily separated, ensuring that the two conductive strips 2 can stably achieve electrical conduction.

[0054] The pressure exerted by the driving conductive connector 3 against the conductive strip 2 can come from external components or from the elasticity of the conductive connector 3 itself; several specific implementation methods are described below:

[0055] Example 1

[0056] like Figure 1-6 As shown in the figure, this embodiment illustrates a conductive strip splicing structure for a curtain machine, which includes a guide rail section 1, a conductive strip section 2, and a conductive splice 3, as well as a first pressing member 5 and a second pressing member 6; a portion of the conductive splice 3 is pressed by the first pressing member 5 to abut against the conductive strip section 2 within one guide rail section 1, and the other portion of the conductive splice 3 is pressed by the second pressing member 6 to abut against the conductive strip section 2 within another guide rail section 1.

[0057] In this embodiment, a mounting base 4 is also included, which is disposed between two guide rail segments 1; the conductive connector 3 is a long strip-shaped metal piece, with both ends of the conductive connector 3 connected to the mounting base 4, and the conductive connector 3 is located between the mounting base 4 and the conductive strip segment 2; the first pressing member 5 and the second pressing member 6 are both screws, which are threaded onto the mounting base 4, and one end of the screw presses against the conductive connector 3 so that the conductive connector 3 is tightly pressed onto the conductive strip segment 2.

[0058] In this embodiment, the mounting base 4 is disposed inside the guide rail section 1, and the mounting base 4 is slidably disposed along the length direction of the guide rail section 1. When the first pressing member 5 and the second pressing member 6 are tightened (that is, the end of the screw presses the conductive connector 3 onto the conductive strip section 2), the position of the mounting base 4 within the guide rail section 1 can be fixed.

[0059] In this embodiment, the screw tightening method ensures a large clamping force between the conductive connector 3 and the conductive strip 2, making the connection between the two stable and not easily separated by external pulling. Multiple first clamping members 5 and second clamping members 6 can be provided respectively.

[0060] According to the prior art CN201263033Y, the entire track formed by splicing the guide rail section 1 will have a reciprocating movable body (not shown) inside, which realizes the opening and closing of the curtain. In this embodiment, the mounting base 4 will hinder the movement of the movable body. Therefore, the mounting base 4 in this embodiment is more suitable for the splicing position between two curtains, and the movable body does not need to pass through this position.

[0061] Furthermore, it should be noted that regarding the structure of guide rail section 1, one embodiment is as follows: Figure 6As shown, the guide rail section 1 includes an outer rail 1a and an inner rail 1b. The conductive strip 2 is disposed on the inner rail 1b, and the inner rail 1b is disposed on the outer rail 1a. The inner rail 1b is made of insulating material (such as plastic), and the outer rail 1a is made of metal. In this way, the outer rail 1a is more robust, which makes the structure of the curtain machine guide rail more robust and provides better protection. At the same time, the inner rail 1b can achieve insulation between the conductive strip section 2 and the outer rail 1a. In other embodiments, the inner rail 1b and the outer rail 1a can be omitted, and the guide rail section 1 can be directly manufactured as an integral piece of insulating material.

[0062] It should also be noted that the mounting base 4 and conductive connector 3 mentioned above are only used for electrical conduction connection between the two conductive strip segments 2; to achieve the connection between the guide rail segments 1, such as Figure 1 and Figure 2 As shown, a guide rail connector 100 is also required. In existing electric curtain motors, guide rail splicing is a fairly standard structure, as seen in existing technologies such as CN221635512U, CN117958585A, and CN219895328U. Therefore, the specific structure and splicing principle of the guide rail connector 100 will not be elaborated here. This utility model does not limit the splicing method between guide rail segments 1.

[0063] Example 2

[0064] like Figure 7-11 As shown in the figure, Embodiment 2 illustrates a conductive strip splicing structure for a curtain machine, which also includes a guide rail section 1, a conductive strip section 2, a conductive splice 3, a first crimping member 5, a second crimping member 6, and a mounting base 4. The difference between Embodiment 2 and Embodiment 1 is that the mounting base 4 in Embodiment 2 is located outside the guide rail section 1.

[0065] Specifically, the outer side of the guide rail section 1 is provided with a clearance hole 11 to allow the conductive strip section 2 to contact the outside. The conductive connector 3 is disposed within the clearance hole 11 to achieve contact with the conductive strip section 2. In other words, the mounting base 4 is not disposed inside the guide rail section 1, so there is no problem of the mounting base 4 obstructing the movement of the movable body, thereby making the splicing and installation position of the mounting base 4 less restrictive.

[0066] In this embodiment, a channel 41 is formed inside the mounting base 4, and the guide rail section 1 is slidably disposed in the channel 41. A locking hole 42 is provided on the mounting base 4, and a locking screw 43 is threadedly connected inside the locking hole 42. The end of the locking screw 43 abuts against the outside of the guide rail section 1 to achieve relative fixation between the mounting base 4 and the guide rail section 1.

[0067] In other words, the mounting base 4 functions as a guide rail connector 100. The mounting base 4 can not only achieve electrical conduction connections between conductive strip segments 2, but also connect guide rail segments 1. Specifically, as... Figure 7 As shown, insert the two guide rail segments 1 from both ends of the mounting base 4 respectively. The clearance holes 11 on the guide rail segments 1 will correspond to the positions of the conductive connecting strips on the mounting base 4. Then tighten the locking screws to splice and fix the two guide rail segments 1. Then tighten the first crimping piece 5 and the second crimping piece 6 to realize the electrical conduction connection between the two conductive strip segments 2.

[0068] Example 3

[0069] like Figure 12-15 As shown, Embodiment 3 illustrates a conductive strip splicing structure for a curtain machine, which includes a guide rail section 1, a conductive strip section 2, and a conductive splice 3. The difference between Embodiment 3 and Embodiments 1 and 2 is that the conductive splice 3 in Embodiment 3 provides pressure by pressing against the conductive strip section 2 through its own elasticity. Therefore, Embodiment 3 does not require the use of a first pressing member 5 and a second pressing member 6.

[0070] In this embodiment, the two ends of the conductive connector 3 are respectively formed with elastic expansion and contraction portions 31, and the end of the guide rail segment 1 is provided with a socket 12 for the elastic expansion and contraction portion 31 to be inserted. The conductive strip segment 2 is located on the side of the socket 12. The width of the elastic expansion and contraction portion 31 in its natural state is greater than the width of the socket 12. After the elastic expansion and contraction portion 31 is inserted into the socket 12, one side of the elastic expansion and contraction portion 31 is pressed and contacts the conductive strip segment 2.

[0071] In other words, when the elastic expansion portion 31 is inserted into the socket 12, the elastic expansion portion 31 is compressed, so the elastic expansion portion 31 will be in a state that tends to expand and reset, and the elastic force of the expansion and reset will cause the conductive connector 3 to press tightly against the conductive strip 2.

[0072] More specifically, such as Figure 13 As shown, the conductive connector 3 in this embodiment is a long strip-shaped metal piece. The conductive connector 3 includes a conductive connector body 3a. The two ends of the conductive connector body 3a are bent to form a first bent segment 3b and a second bent segment 3c, respectively. An expansion space 3d is formed between the first bent segment 3b and the conductive connector body 3a, and between the second bent segment 3c and the conductive connector body 3a.

[0073] In this embodiment, the installation and removal of the conductive connector 3 is relatively simple. The conductive connector 3 can be installed and removed by inserting and pulling. Specifically, in practical applications, the conductive connector 3 is first inserted into the socket 12 of the two guide rail segments 1, and then the two guide rail segments 1 are fixed together by the guide rail connector 100. In this way, the conductive connector 3 will not come out of the socket 12, which can ensure a stable connection between the two conductive segments 2.

[0074] Example 4

[0075] like Figure 16 As shown, Embodiment 4 provides a conductive strip splicing structure for a curtain machine, which includes a guide rail section 1, a conductive strip section 2, a conductive splice 3, a first pressing member 5, and a second pressing member 6; wherein, Embodiment 4 differs from Embodiments 1 and 2 in that Embodiment 4 does not use a mounting base 4; Embodiment 4 differs from Embodiment 3 in that, in Embodiment 4, pressure is provided by the first pressing member 5 and the second pressing member 6.

[0076] Specifically, the conductive connector 3 is a long strip-shaped metal piece, and the first crimping member 5 and the second crimping member 6 are elastic rubber blocks fixed at both ends of the conductive connector 3; the end of the guide rail section 1 is provided with a socket 12, and the conductive strip section 2 is located on the side of the socket 12; the first crimping member 5 and the second crimping member 6 are respectively inserted into the sockets 12 of the two guide rail sections 1, and the width of the first crimping member 5 and the second crimping member 6 in their natural state is greater than the width of the socket 12.

[0077] Thus, Embodiment 4 also has the advantage of easy assembly and disassembly of the conductive connector 3 as in Embodiment 3. Furthermore, if the conductive connector 3 is made of a conductive metal with poor elasticity, the conductive connector 3 itself cannot form an elastic expansion and contraction portion 31, making the structure of Embodiment 4 even more suitable.

[0078] In the above embodiments, in order to make the contact between the conductive strip 2 and the conductive connector 3 more stable, the conductive strip 2 is a long strip of metal, such as a copper strip; the conductive connector 3 is also a long strip of metal, so that there is a large contact area between the conductive connector 3 and the conductive strip 2.

[0079] In summary, this utility model provides a conductive strip connection structure for a curtain machine. In this conductive connection structure, by forming a compression fit between the conductive connector 3 and the conductive strip segment 2, the friction between the conductive connector 3 and the conductive strip segment 2 is increased, so that the conductive connector 3 and the conductive strip segment 2 are effectively connected and not easily separated, ensuring that the two conductive strip segments 2 can stably achieve electrical conduction.

[0080] 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.

[0081] 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.
