Description

[Technical Field]

[0001] The present invention relates to the technical field of tubular motors, and more particularly to the stroke head of a tubular motor. [Background technology]

[0002] Tubular motors are often used in shutters, and when the tubular motor is inserted into a roll pipe, the stroke head of the tubular motor is exposed from the outside of the roll pipe. In the prior art, the antenna for receiving signals from the stroke head is generally installed outside the stroke head. Although the exposed antenna can easily receive signals, because it is close to the side of the shutter body, it is easily entangled in the body when the shutter is rolled up, causing problems such as antenna damage and breakage, and ultimately causing the antenna to fail. To solve this problem, some structures have been used in which the antenna is wound inside the stroke head, but due to the limited internal space, messy winding not only interferes with internal components, but also makes installation very inconvenient. Summary of the Invention [Problem to be solved by the invention]

[0003] In contrast to the above-mentioned state of the art, the technical problem that the present invention aims to solve is to provide a stroke head for a tubular motor that not only allows for concealed installation of an antenna, but also is easy to install and has a neat structure. [Means for solving the problem]

[0005] Furthermore, a removably connected end plate is provided at the large-diameter end of the case, and the end plate is connected to the case by screws. At least two threaded sleeves are provided in the mounting cavity, and the end plate has through holes corresponding to the threaded sleeves, and the screws are threaded into the threaded sleeves after passing through the through holes.

[0006] Furthermore, the threaded sleeve is positioned in the circumferential direction of the PCB substrate, and the PCB substrate is provided with a locking groove that engages with the threaded sleeve, and the locking groove is U-shaped.

[0010] Furthermore, the flexible vibration-damping sleeve is made of rubber or silica gel, and the hard support sleeve is made of plastic.

[0011] Furthermore, the case is not an electromagnetic shield case, but is made of a material that does not shield electromagnetic signals, and / or has gaps in the case that allow electromagnetic leakage.

[0012] Furthermore, the width of the passage is greater than the outer diameter of the antenna and less than twice the outer diameter of the antenna. [Effects of the Invention]

[0013] Compared with the prior art, the advantages of this invention are as follows: In this invention, a passage for winding the antenna is provided within the case, so the antenna is installed concealed within the case, preventing it from being entangled and damaged by the shutter body, and it can also be neatly wound within the passage, making installation easier; the antenna and PCB board are spaced apart from each other within the case 1, so the antenna winding does not interfere with components on the PCB board, improving safety and increasing the service life. [Brief explanation of the drawings]

[0014] [Figure 1] FIG. 2 is a structural diagram of the present invention. [Figure 2] FIG. 2 is a structural diagram of the present invention without the end plate. [Figure 3] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0015] The present invention will be further described below in conjunction with specific embodiments.

[0016] As shown in Figures 1 to 3, the present invention provides a stroke head for a tubular motor, which includes a case 1, a PCB board 2 installed inside the case 1, the case 1 having a T-shaped cylindrical structure, a mounting cavity 1.1 for accommodating the PCB board 2 within the larger diameter end of the case 1, an antenna 3 for receiving signals is electrically connected to the PCB board 2, and a passage 1.2 for winding the antenna 3 is provided within the mounting cavity 1.1 between the outer periphery of the PCB board 2 and the inner wall of the mounting cavity 1.1.

[0017] In this invention, a passage 1.2 for winding the antenna 3 is provided within the case 1, so that the antenna 3 is installed concealed within the case 1 and can be prevented from being entangled and damaged by the shutter body. It can also be wound neatly and regularly within the passage 1.2, making installation easier. The antenna 3 and the PCB board 2 are spaced apart from each other within the case 1, so that the winding of the antenna 3 does not interfere with the components on the PCB board 2, making it safer and increasing its service life. Furthermore, the passage 1.2 for winding the antenna 3 is positioned to adhere to the inner wall of the mounting cavity 1.1, so there is no interference around the antenna 3 and the signal reception range is wider.

[0018] Referring to Figures 1 and 3, the case 1 has a detachable end plate 4 at the large end, which is connected to the case 1 by screws 5. The mounting cavity 1.1 has at least two threaded sleeves 1.3, which are provided with through holes 4.1 corresponding to the threaded sleeves 1.3. The screws 5 are threaded into the threaded sleeves 1.3 after passing through the through holes 4.1. This detachable structure facilitates assembly, disassembly, and maintenance. The thread sleeve 1.3 is positioned around the periphery of the PCB board 2, and the PCB board 2 is provided with a locking groove 2.1 that engages with the thread sleeve 1.3. The locking groove 2.1 is U-shaped, and the engagement between the locking groove 2.1 and the thread sleeve 1.3 can position and fix the PCB board 2. Preferably, there are three thread sleeves 1.3, distributed triangularly around the periphery of the PCB board 2, which not only makes the positioning of the PCB board 2 more stable, but also makes the connection between the end plate 4 and the case 1 more stable.

[0019] 2 and 3, a notch 1.4 is provided on the side wall of the passage 1.2 near the PCB board 2, and a fastening portion 2.2 that fits into the notch 1.4 is provided on the PCB board 2, and the notch 1.4 is connected to the fastening portion 2.2, thereby further positioning and fixing the PCB board 2. The provision of the notch 1.4 also makes it easy for the antenna 3 electrically connected to the PCB board 2 to penetrate through the notch 1.4 into the passage 1.2 and wrap around it. Preferably, there are two notches 1.4 arranged symmetrically.

[0020] Preferably, the passage 1.2 is U-shaped, and is arranged in a U-shape so that the passage 1.2 does not completely surround the mounting cavity 1.1. The side wall of the mounting cavity 1.1 that is not surrounded by the passage 1.2 can be easily provided with ports for switches, ports for setting keys, power connection and data interfaces, etc. Generally, the switches, setting keys, power connection and data modules that are easy for users to operate are exposed on the outside of the stroke head. The switches, setting keys, power connection and data modules are all electrically connected to the PCB board 2, and the corresponding ports for switches, setting keys, power connection and data interfaces can be easily provided on the outside of the stroke head. The setting key port, power connection and data interface must be exposed on the outside of the stroke head; the switch can control operation; the setting key can perform pairing, switching and factory reset; and the power connection and data module can charge and communicate data. The U-shaped arrangement of passage 1.2 can maximize the wrapping and accommodation of antenna 3, not only increasing the signal reception range of antenna 3 but also avoiding the switch, setting key, power connection and data module on PCB board 2, making installation easier and the structure neater.

[0021] Referring to FIG. 3, a flexible vibration-damping sleeve 6 is connected to the small-diameter end of the case 1, and a hard support sleeve 7 is fitted onto the flexible vibration-damping sleeve 6. The combined installation of the flexible vibration-damping sleeve 6 and the hard support sleeve 7 can serve to damp vibration and reduce noise when the stroke head is connected to the motor part of a tubular motor. The flexible vibration-damping sleeve 6 absorbs and filters vibrations generated by the motor part, reducing the transmission of vibrations. The hard support sleeve 7 supports the flexible vibration-damping sleeve 6 to prevent it from deforming, thereby extending the service life of the flexible vibration-damping sleeve 6. The flexible vibration-damping sleeve 6 is made of rubber or silica gel and can filter and absorb vibrations and reduce noise. The hard support sleeve 7 is made of plastic and supports the flexible vibration-damping sleeve 6 to prevent it from deforming.

[0022] Preferably, the case 1 is not an electromagnetic shielding case, but is made of a material that does not shield electromagnetic signals, and / or the case 1 has gaps that allow electromagnetic leakage.Furthermore, materials that do not shield electromagnetic signals can be selected from plastic, rubber, wood-based plastic materials, etc., which are insulating and / or non-magnetically permeable materials, and avoid shielding signals to the antenna 3.

[0023] Here, the width of the passage 1.2 is larger than the outer diameter of the antenna 3 and smaller than twice the outer diameter of the antenna 3, so that the antenna 3 can be easily wound back and forth and stacked regularly, making it easier to install.

[0024] During assembly, the antenna 3 electrically connected to the PCB board 2 is inserted into the passage 1.2 through the nearby notch 1.4, and the antenna 3 is wound back and forth along the passage 1.2. The so-called back and forth winding refers to winding back and forth along the passage 1.2 in a counterclockwise and then clockwise order, or in a clockwise and then counterclockwise order. If the antenna 3 is short and only one winding is required, or if the antenna 3 is long and multiple windings are required, after winding the antenna 3, the end plate 4 is covered and fastened with the screws 5, which simplifies installation. The antenna 3 is installed so as to be concealed within the case 1, which prevents it from being entangled and damaged by the shutter body. Furthermore, the antenna 3 is stored in the passage 1.2 at a distance from the PCB board 2, so that they do not interfere with each other. The winding structure is neat and regular, and it is safe to use.

[0025] The materials, reagents and experimental equipment used in the embodiments of the present invention are all commercially available products that are suitable for the field of tubular motors for electric curtains, unless otherwise specified. [Explanation of symbols]
