Technical Field

[0001] This utility model relates to the field of tubular motor technology, and in particular to a tubular motor with electronic travel limit. Background Technology

[0002] Tubular motors are widely used in roller shutters, awnings, blinds, and other similar equipment. They drive the opening and closing of curtains or shading components to achieve functions such as sun shading, lighting, and privacy protection. Generally, the upper and lower limit positions of roller shutters are adjusted manually using mechanical travel components and corresponding screws. Due to the large size of the mechanical travel components, the overall size of the tubular motor has to be increased, making installation inconvenient, and resulting in more parts and maintenance difficulties, thus shortening its service life. In addition, if the roller shutter is installed in a high position, the operator needs to climb to the corresponding position before adjusting the upper and lower limit positions of the roller shutter.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-2 This is the first embodiment of the present invention. This embodiment provides a tubular motor with electronic travel limit. The tubular motor with electronic travel limit includes a main body assembly 100, including a travel cover 101. A travel seat 102 is provided on the upper end of the travel cover 101. The travel cover 101 and the travel seat 102 are connected by bolts. A plate cover 103 is provided on one side of the travel seat 102. A bridge gear 104 is connected to one end of the plate cover 103 by a bearing. A travel base 105 is provided on one side of the travel cover 101. A manual worm gear 106 is connected to the travel base 105 by a bearing. A gear ring 107 is connected to the travel base 105 by a bearing. A limit gear 108 meshes inside the gear ring 107. The limit gear 108 and the bridge gear 104 are fixed by a connecting rod, so that when the bridge gear 104 rotates, it can simultaneously drive the limit gear 108 to rotate on the gear ring 107, thereby causing the gear ring 107 to start rotating.

[0029] An encoder 109 is provided on one side of the travel cover 101. One side of the encoder 109 fits against the cover 103. A groove 102-1 is provided on the travel seat 102, which is the same shape as the cover 103. The cover 103 is used to limit the position of the encoder 109 in conjunction with the groove 102-1. The encoder 109 is installed in the groove 102-1. The encoder 109 is a standard part of the electronic forming component and is used to control the upper and lower limit positions of the tubular motor. The encoder 109 can be remotely controlled by a corresponding remote controller. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0030] The use of encoder 109 replaces the traditional mechanical stroke components, reducing the size of the stroke components and thus the overall size of the tubular motor, making it easier to install. At the same time, when adjusting the stroke limit of the tubular motor, the operator does not need to climb to the corresponding position; they can simply control encoder 109 to adjust the limit via remote control.

[0031] A transmission assembly 1010 is provided on one side of the manual worm gear 106. The transmission assembly 1010 is used to connect to the roller shutter door's roller shaft, so that the rotation of the manual worm gear 106 can drive the roller shaft to rotate, thereby controlling the roller shutter door. A sprocket 1011 is fixed to one end of the manual worm gear 106. A chain 1012 is wound around the sprocket 1011. The sprocket 1011 and the chain 1012 cooperate with each other, allowing the manual worm gear 106 to be manually driven to rotate, thereby adjusting the roller shutter door. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0032] Example 2

[0033] Reference Figures 3-7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, it also includes a mounting component 200, which is located on one side of the cover 103 and includes a mounting piece 201 for stably fixing the encoder 109 to the travel seat 102.

[0035] Mounting component 201 includes mounting base 2011 fixed on travel seat 102. Mounting base 2011 is fixed on the inner wall of groove 102-1. Mounting base 2011 has mounting groove 2011-1. The shape of mounting groove 2011-1 corresponds to encoder 109. Encoder 109 is set in mounting groove 2011-1. Cover 103 is also set in mounting groove 2011-1. When installing encoder 109, encoder 109 is first placed in mounting groove 2011-1, and then cover 103 is placed on top of encoder 109. The edge of cover 103 fits against the inner wall of groove 102-1.

[0036] The mounting base 2011 has a cylindrical groove 2011-2, and the cover plate 103 has a through groove 103-1 corresponding to the cylindrical groove 2011-2. After the encoder 109 and the cover plate 103 are placed, the cylindrical groove 2011-2 and the through groove 103-1 will be in a coaxial position.

[0037] Specifically, a mounting post 2012 is provided in the cylindrical groove 2011-2. The mounting post 2012 is used to limit the position of the cover 103 and prevent the cover 103 from separating from the groove 102-1, thereby ensuring the stable installation of the encoder 109. A first moving groove 2012-1 is provided on the mounting post 2012. A locking block 2013 is provided in the first moving groove 2012-1. A locking groove 2011-3 is provided on the mounting base 2011. The locking block 2013 can be engaged with the locking groove 2011-3. One end of the locking block 2013 is inclined and the locking groove 2011-3 has a corresponding shape. A protrusion is fixed on the mounting post 2012, and the inner wall of the cylindrical groove 2011-2 has a corresponding slot. During installation, the slot and the locking block are aligned so that the mounting post 2012 can be inserted into the cylindrical groove 2011-2 and the through groove 103-1.

[0038] Two locking blocks 2013 are provided inside a mounting post 2012 to ensure that the mounting post 2012 will not easily separate from the mounting base 2011.

[0039] As the mounting post 2012 is inserted into the cylindrical groove 2011-2, the inclined end face of the locking block 2013 will first contact the end face of the mounting base 2011. The mounting base 2011 will press against the inclined surface of the locking block 2013, causing the locking block 2013 to move into the first moving groove 2012-1 without obstructing the movement of the mounting post 2012. When the locking block 2013 moves to a position coaxial with the locking groove 2011-3, the two will engage, and the locking block 2013 will prevent the mounting post 2012 from separating from the mounting base 2011.

[0040] Specifically, the mounting column 2012 has a lifting groove 2012-2, and a lifting column 2014 is installed in the lifting groove 2012-2. The lifting column 2014 is used to release the locking block 2013 from the locking groove 2011-3. A connecting plate 2015 is fixed on the lifting column 2014, and a push block 2016 is fixed on the connecting plate 2015. The mounting column 2012 has a second moving groove 2012-3 corresponding to the connecting plate 2015 and the push block 2016.

[0041] In the initial state, the bottom of the lifting column 2014 is in contact with the inner wall of the lifting groove 2012-2. When the lifting column 2014 moves upward, it will simultaneously drive the connecting plate 2015 and the push block 2016 to move upward along the connecting plate 2015 and the push block 2016.

[0042] Specifically, the locking block 2013 has an inclined groove 2013-1, and the push block 2016 is a right-angled triangle. Its inclined surface can engage with the inclined groove 2013-1. When the locking block 2013 engages with the locking groove 2011-3, the bottom of the lifting column 2014 is in contact with the inner wall of the lifting groove 2012-2, and part of the inclined surface of the push block 2016 contacts the inclined groove 2013-1. As the lifting column 2014 moves upward, the inclined surface of the push block 2016 will press against the inclined groove 2013-1, thereby separating the locking block 2013 from the locking groove 2011-3. Then the mounting column 2012 can be removed from the cylindrical groove 2011-2, and then the cover 103 can be removed, and then the encoder 109 can be removed.

[0043] Specifically, a first spring 2017 is fixed to one end of the locking block 2013, and the other end of the first spring 2017 is fixed to the inner wall of the first moving groove 2012-1. The first spring 2017 is used to apply a continuous pushing force to the locking block 2013 to ensure that the locking block 2013 can engage with the locking groove 2011-3.

[0044] The first moving groove 2012-1 is also fixed with a guide post 20111, and the locking block 2013 has a guide groove 2013-2. The guide post 20111 is inserted into the guide groove 2013-2. Through the cooperation of the two, it is ensured that the locking block 2013 can move smoothly along the first moving groove 2012-1.

[0045] Example 3

[0046] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a baffle 2018 is fixed on one side of the mounting post 2012. After the mounting post 2012 is installed in place, the baffle 2018 will fit against the cover 103. The size of the baffle 2018 is larger than the through slot 103-1. Therefore, after the position of the mounting post 2012 is fixed, the baffle 2018 can prevent the cover 103 from moving, thereby ensuring the stability of the encoder 109 installation.

[0048] Specifically, a pull plate 2019 is fixed on one side of the lifting column 2014. Pulling the pull plate 2019 can move the lifting column 2014 upward.

[0049] Specifically, a second spring 20110 is fixed on the pull plate 2019, and the other end of the second spring 20110 is fixed on the baffle 2018. The second spring 20110 provides continuous pressure to the baffle 2018 to ensure that the bottom of the lifting column 2014 can fit against the inner wall of the lifting groove 2012-2 without other external forces.

[0050] When it is necessary to disassemble the encoder 109, pull the pull plate 2019 upward, the second spring 20110 will be stretched, thereby moving the lifting column 2014, thereby releasing the locking block 2013 from the locking groove 2011-3. Then, continue to pull the pull plate 2019, the second spring 20110 will also apply a pulling force to the baffle 2018, thereby making the baffle 2018 and the mounting column 2012 move upward synchronously, thereby separating the mounting column 2012 from the cylindrical groove 2011-2. Then, the cover 103 and the encoder 109 can be removed in sequence.

[0051] Specifically, the cylindrical grooves 2011-2 and the through grooves 103-1 are the same in number and correspond to each other, with a total of three sets. There are three corresponding mounting bases 2011. The mounting base 2011 is also provided with a threaded groove, in which a bolt is threadedly connected. This bolt can not only connect the plate cover 103 to the mounting base 2011, but also connect the travel cover 101 to the travel seat 102.

[0052] When in use, the encoder 109 is controlled by the corresponding remote control to adjust the upper and lower travel limit positions of the tubular motor.

[0053] When installing the encoder 109, first place the encoder 109 in the mounting slot 2011-1, then place the cover 103 above the encoder 109, with the edge of the cover 103 fitting against the inner wall of the groove 102-1. Next, insert the mounting post 2012 into the cylindrical groove 2011-2 and the through groove 103-1. As the mounting post 2012 is inserted into the cylindrical groove 2011-2, the inclined end face of the locking block 2013 will first contact the end face of the mounting base 2011. The locking block 2013 is pressed against the inclined surface, causing it to move into the first moving groove 2012-1 without obstructing the movement of the mounting post 2012. When the locking block 2013 moves to a position coaxial with the locking groove 2011-3, the two will engage. The locking block 2013 will prevent the mounting post 2012 from separating from the mounting base 2011, thereby limiting the position of the cover 103 and preventing the cover 103 from separating from the groove 102-1, thus ensuring the stable installation of the encoder 109.

[0054] When it is necessary to disassemble the encoder 109, pull the pull plate 2019 upward, the second spring 20110 will be stretched, the lifting column 2014 will move upward, and the connecting plate 2015 and the push block 2016 will move upward along the connecting plate 2015 and the push block 2016. The inclined surface of the push block 2016 will squeeze the inclined groove 2013-1, thereby separating the locking block 2013 from the locking groove 2011-3 and releasing the position lock of the mounting column 2012. Then, continue to pull the pull plate 2019, and the second spring 20110 will also apply a pulling force to the baffle 2018, so that the baffle 2018 and the mounting column 2012 can move upward synchronously, thereby separating the mounting column 2012 from the cylindrical groove 2011-2. After that, the cover 103 and the encoder 109 can be removed in sequence.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
