DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] It should be noted that in the claims and description of this patent, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one" do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0030] The utility model discloses a tubular motor stroke structure, referring to Figure 1-11 As shown, it includes a base 100 and a switch member 200 , wherein the switch member 200 is arranged on the base 100 , and further includes: a conductive slip ring 300 , wherein at least part of the conductive slip ring 300 is arranged in the base 100 or the conductive slip ring 300 is located on the fixed sleeve, and the conductive slip ring 300 is transmission-connected with the switch member 200 .

[0031] like Figure 5 , 9 As shown, the base 100 is preferably formed by splicing two shells. The switch member 200 is preferably an inner gear sleeve, which is rotatably connected to the base 100. The inner gear sleeve is used to connect with an external load. When the external load rotates around the motor under the drive of the motor, it can drive the inner gear sleeve to rotate at the same time, and the rotation of the inner gear sleeve drives the stroke part 500 to operate. When the inner gear sleeve rotates, the conductive slip ring 300 will also rotate accordingly.

[0032] The conductive slip ring 300 has two installation positions. One is that the conductive slip ring 300 replaces the original plastic rotating block and the installation position is the same as the plastic rotating block. Since the conductive slip ring 300 itself is small, the required installation space is small, which can shorten the length of the motor housing.

[0033] Secondly, the conductive slip ring 300 is preferably installed in the base 100, and the conductive slip ring 300 is coaxially connected with the inner gear sleeve. The conductive slip ring 300 replaces the original drive assembly and is installed in the base 100, which greatly saves installation space and can shorten the length of the motor housing.

[0034] The conductive slip ring 300 itself can achieve the purpose of rotating the electric wire 900 without entanglement. As for the specific structure inside the conductive slip ring 300, it is a prior art, and reference can be made to patents CN117954926A, CN219659120U and other documents.

[0035] like Figure 7As shown, the conductive slip ring 300 is also called a collector ring, slip ring, collector ring, collector ring, etc. It can be applied to any electromechanical system that requires continuous rotation and needs to transmit power and signals from a fixed position to a rotating position. The conductive slip ring 300 can improve system performance, simplify system structure, and avoid twisting of the wire during rotation. The conductive slip ring 300 can be installed in the base 100 to achieve the electromechanical system that requires continuous rotation and needs to transmit power and signals from a fixed position to a rotating position. Compared with the original installation between the control board and the stroke part 500, the installation space is saved, and the length required for the motor housing corresponding to the installation space is correspondingly shortened.

[0036] Specifically, Fig.10 , 11 As shown, the base 100 also includes: a rotating sleeve 400, at least part of which extends out of the base 100; a switch member 200 is sleeved on the part of the rotating sleeve 400 extending out of the base 100; and a cavity 410 is arranged in the rotating sleeve 400, at least part of which is located in the conductive slip ring 300.

[0037] A portion of the rotating sleeve 400 is extended out of the base 100, which can ensure that the switch member 200 is sleeved on the outside of the rotating sleeve 400, so that the switch member 200 can be connected to an external load and rotate under the drive of the motor, and the corresponding rotating sleeve 400 can also rotate, and the cavity 410 in the rotating sleeve 400 is used to accommodate the conductive slip ring 300. When the rotating sleeve 400 rotates, the conductive slip ring 300 rotates together, and the conductive slip ring 300 can realize the transmission of power and signals from a fixed position to a rotating position, and ensure that the wires 900 are not entangled.

[0038] Preferably, the diameter of the conductive slip ring 300 is slightly smaller than the diameter of the cavity 410, so that the conductive slip ring 300 can be placed in the cavity 410 and can fit more tightly, ensuring that the conductive slip ring 300 does not wobble during operation.

[0039] Specifically, Figure 7 As shown, the conductive slip ring 300 includes: a main body portion, at least part of which is located in the cavity 410 of the rotating sleeve 400; and a mounting portion, which is connected to the main body portion.

[0040] The conductive slip ring 300 includes a main body, and the specific structure in the main body is the prior art. In order to ensure that the conductive slip ring 300 can be installed in the rotating sleeve 400, a mounting portion is provided, and the mounting portion can be a flange and then installed by screws, or it can be a snap-fit ​​installation by a snap-fit ​​part through interference fit, and it is sufficient to ensure that a part of the main body is installed in the cavity 410 of the rotating sleeve 400. Since the conductive slip ring 300 and the rotating sleeve 400 have a partial overlap in the axial installation space, the corresponding axial installation space can be reduced, and the corresponding motor housing 800 length can be shortened, saving costs.

[0041] Specifically, Figure 7 As shown, the mounting portion includes a mounting plate 310, which is connected to the rotating sleeve 400; the mounting plate 310 is provided with a channel for the main body to pass through.

[0042] The mounting part is preferably a mounting plate 310, which is a flange plate, and a passage for the main body to pass through is provided on the flange plate, and screw holes are provided on the end surface of the flange plate, so that the flange plate can be connected to the rotating sleeve 400 by passing a connecting member such as a screw through the screw holes. The mounting plate 310 can be mounted on the end surface of the rotating sleeve 400, so that the conductive slip ring 300 can be mounted on the rotating sleeve 400.

[0043] Specifically, Figure 7 As shown, the main body includes: a first joint portion 320, at least part of which is disposed in the cavity 410 of the rotating sleeve 400; a second joint portion 330, which is disposed outside the rotating sleeve 400; and the first joint portion 320 is connected to the second joint portion 330.

[0044] The first joint part 320 is at least partially installed in the cavity 410 of the rotating sleeve 400, and preferably the first joint part 320 is installed in the cavity 410 of the rotating sleeve 400. The overlapping installation space of the first joint part 320 and the rotating sleeve 400 in the axial direction is maximized, so that the corresponding axial installation space can be reduced to the maximum, and the corresponding length of the motor housing 800 can be shortened to the maximum, saving costs. The second joint part 330 is arranged outside the rotating sleeve 400, so that the wire 900 passes through the second joint part 330 to the wire hole 110 on the base 100.

[0045] Specifically, the outer diameter of the first joint portion 320 is greater than the outer diameter of the second joint portion 330 .

[0046] The diameter of the second joint part 330 is smaller than that of the first joint part 320, and the corresponding limiting part of the second joint part 330 is smaller, so that multiple wires 900 can be restricted at the same time, and the gap between the wires 900 and the side wall of the second joint part 330 can be small, so that multiple wires 900 can be restricted and fixed by the limiting part of the second joint part 330 when passing through the second joint part 330.

[0047] Specifically, Figure 7 , 10 As shown, it also includes: a positioning member 600, which is fixedly connected to the rotating sleeve 400; a positioning hole 340, which is arranged on the mounting plate 310 of the conductive slip ring 300; wherein the positioning member 600 cooperates with the positioning hole 340 to enable the conductive slip ring 300 to be installed in the rotating sleeve 400.

[0048] The positioning member 600 is preferably a cylinder, fixedly connected to the rotating sleeve 400, and arranged along the circumference of the rotating sleeve 400. The number of the positioning holes 340 is preferably three, arranged along the circumference of the mounting plate 310, and the diameter of the positioning member 600 is adapted to the diameter of the positioning hole 340, so that the positioning member 600 can be inserted into the positioning hole 340 to achieve assembly positioning.

[0049] Specifically, Figure 6 , 8 As shown, the base 100 further includes a worm wheel 700 , which is meshed with a hand-cranked worm 710 , and a receiving cavity 720 is provided in the side wall of the worm wheel 700 , and the mounting plate 310 is located in the receiving cavity 720 .

[0050] The stroke head needs to be adjusted manually when necessary, so a worm wheel 700 is provided in the base 100, and the worm wheel 700 is meshed with a hand-cranked worm 710, and the hand-cranked worm 710 is hollow, and an external tool such as a plug is inserted into the hand-cranked worm 710, and the plug drives the hand-cranked worm 710 to rotate, so that the hand-cranked worm 710 drives the worm wheel 700 to rotate, and drives the rotating sleeve 400 to rotate to replace the motor to drive the switch 200 to rotate. The mounting plate 310 is installed in the accommodating cavity 720 of the side wall of the worm wheel 700, and one end of the mounting plate 310 is in contact with the end surface of the rotating sleeve 400 to ensure the stable installation of the mounting plate 310.

[0051] Specifically, it also includes a travel portion 500, which is arranged between the switch member 200 and the control board;

[0052] The wires 900 on the control board pass through the travel portion 500 and the conductive slip ring 300 to the base 100 .

[0053] like Figure 2-5 As shown, the specific principle of the stroke part 500 can refer to a tubular motor stroke mechanism disclosed in patent publication number CN217335335U. This application mainly describes the relevant technical features of omitting the drive assembly / plastic rotor block and using a conductive slip ring 300 for installation.

[0054] Control panel (not shown), see Figure 1 , Figure 2Located on the left side of the stroke part 500, inside the motor housing 800. In the prior art, the wires 900 on the control board pass through the drive assembly and then through the stroke part 500 to the base 100. In this application, when the conductive slip ring 300 is used to be installed in the base 100, the wires 900 on the control board preferably pass through the stroke part 500 first and then through the conductive slip ring 300 to the base 100. When the conductive slip ring 300 is used to be installed on the fixed seat, the wires 900 first pass through the conductive slip ring 300 and then through the stroke part 500 to the base 100. This can shorten the length of the motor housing, reduce the material used for the motor housing, reduce costs, and make the internal structure layout of the tubular motor stroke structure more reasonable, which has practical application significance.

[0055] Specifically, the rotating sleeve 400 is provided with a threading hole 420 through which the power supply line 900 passes.

[0056] The wires 900 on the control board are passed through the wire holes 420 on the rotating sleeve 400, and corresponding wire holes 420 are also provided on the base in the corresponding stroke part 500. The wires 900 on the control board pass through the wire holes 420 on the base in the stroke structure, the wire holes 420 on the rotating sleeve 400, and the conductive slip ring 300 in the rotating sleeve 400, and finally extend from the wire holes 110 on the base 100 to the outside of the base 100.

[0057] At the same time, since the wires 900 entering the base 100 will eventually extend out of the base 100 and connect to a power source, a wire hole 110 is also provided on the base 100, through which the wires 900 in the base 100 are passed to the outside of the base 100 and finally connected to a power source.
