[0037] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure.
[0039] See Figure 1 The electric lifting bracket of the present invention includes a control module 10 , a lifting assembly 20 and a supporting assembly 30 .
[0040] See Figure 2 The control module 10 includes a power supply unit 101, a control unit 102, and a processing unit 103. The power supply unit 101 provides operating voltage to the control unit 102, the processing unit 103, and the motor 2021 of the lifting assembly 20; the control unit 102 is electrically connected to the processing unit 103 and the motor 2021. The processing unit 103 activates the motor 2021 through the control unit 102 and sends a signal to the processing unit 103 to control the forward or reverse rotation or the acceleration or deceleration rotation of the motor 2021 according to the parameters of the control unit 102, thereby achieving the lifting and lowering adjustment of the lifting assembly 20. Among them, the power supply unit 101 can selectively use an energy storage power source, including a solid, semi-solid, or liquid energy storage medium such as a lithium-ion battery or a sodium-ion battery, to provide operating voltage to the control unit 102, the processing unit 103, and the motor 2021 independently of the power transmission mains, or use the power transmission mains or the power transmission line after conversion by a switching power supply to provide operating voltage to the control unit 102, the processing unit 103, and the motor 221. The control unit 102 can be controlled by buttons, a touch screen, or a wireless connection to a mobile client.
[0041] Please see 3. Figure 4 、 Figure 5 The lifting assembly 20 includes a pivot tube 201, a power device 202, a pivot tube 203 and an angle adjustment assembly 204.
[0042] The pivot tube 201 has an internally threaded hollow space 2011. The top of the pivot tube 201 extends outward to form a joint 2012 for mounting the angle adjustment assembly 204. A groove 1 2013 is provided at the bottom of the pivot tube 201, and an inner sleeve 2014 is sleeved within the groove 1 2013. A fixed section 2015 is located between the joint 2012 and the groove 1 2013 on the pivot tube 201. At least one hole 2016 is provided on the fixed section 2015, near the end of the groove 1 2013, for mounting a guide member 2017. A ferrule 2018 is sleeved over the fixed section 2015 of the pivot tube 201.
[0043] The outer side of the clamping ring 2018 is evenly circumferentially provided with clamping protrusions 2018a for fixing the clamping ring 2018.
[0044] The power device 202 includes a motor 2021, a fixing part 2022 for fixing the motor 2021, and a rotating part 2023 with an external thread matching the internal thread of the hollow space 2011 of the pivot tube 201. A shaft hole 2023a matching the output shaft of the motor 2021 is provided on one side of the rotating part 2023. A bearing groove 2023b for accommodating a plane bearing 2024 is provided on one side of the shaft hole 2023a on the rotating part 2023. The plane bearing 2024 is used to reduce the rotational friction damping generated on the support assembly 30; the fixing part 2022 is provided on the fixing seat 2025, and the outer diameter R1 of the fixing part 2022 and the fixing seat 2025 is smaller than the inner diameter R2 of the hollow space 2011 of the pivot tube 201. They are coordinated with each other in such a way that when the rotating part 2023 rotates, the pivot tube 201 can move up and down through the threaded fit and is not restricted by the shape of the fixing part 2022 and the fixing seat 2025.
[0045] It should be noted that the other side of the shaft hole 2023a on the rotating member 2023 is a groove hole 2023c, which matches the hole 2021a on the output shaft of the motor 2021 and can be fixed by screws or bolts. Figure 6 As shown, the output shaft end of the motor 2021 is a square structure, which cooperates with the square groove of the shaft hole 2023a on the rotating part 2023 to achieve fixation. When the motor 2021 is working, it drives the rotating part 2023 to rotate, and the pivot tube 201 that is threadedly matched with the rotating part 2023 moves up and down to realize the lifting function.
[0046] The adjustment accuracy of the lifting component 20 is related to the pitch of the thread. When the pitch distance is small, the motor 2021 is controlled to rotate forward, reverse, quickly or slowly to achieve the corresponding lifting effect.
[0047] The pivot tube 203 includes a through hole 2031, and a guide groove 2031a matching the guide member 2017 on the pivot tube 201 is provided on the inner side of the through hole 2031 along the axial direction of the pivot tube 203; a groove II 2031b matching the clamping ring 2018 on the pivot tube 201 is provided at the top end of the through hole 2031 of the pivot tube 203, and a clamping groove 2031c is provided inside the groove II 2031b at the position corresponding to the clamping protrusion 2018a on the clamping ring 2018, and the clamping ring 2018 is fixed in the groove II 2031b by engaging the clamping protrusion 2018a with the clamping groove 2031c.
[0048] The inner diameter of the ferrule ring is comparable to, or even equal to, the inner diameter of the pivot tube 203, facilitating the upward and downward sliding of the pivot tube 201. The inner sleeve 2014, which is sleeved on the pivot tube 201, protrudes slightly outward, ensuring close contact between the inner sleeve 2014 and the through hole 2031 of the pivot tube 203, preventing any shaking during the upward and downward sliding of the pivot tube 201. The inner sleeve 2014 is made of a high-molecular organic material and has a certain degree of elasticity.
[0049] The guide groove 2031a of the pivot tube 203 corresponds to the guide member 2017 on the pivot tube 201. Specifically, the guide member 2017 can be a roller or a slider that slides up and down within the guide shaft 2031a. This coordination prevents the pivot tube 201 from rotating during its upward and downward sliding. A retaining ring 2018 is located at the top of the guide groove 2031a. When the pivot tube 201 reaches its maximum height, the guide member 2017 contacts the retaining ring 2018 and is restricted from further ascending, preventing the pivot tube 201 from separating from the pivot tube 203.
[0050] It can be seen that the pivot tube 201 , the pivot tube 203 and the fixing seat 2025 are coaxially arranged, wherein the pivot tube 203 and the fixing seat 2025 are coaxially fixed on the base, and the control module 10 is arranged inside the base.
[0051] The angle adjustment assembly 204 includes an angle adjustment body 2041, a damping shaft 2042, and a screw 2043. The angle adjustment body 2041 defines a hole 2041a that mates with the damping shaft 2042. The coupling portion 2012 also defines symmetrical coupling holes 2012a for engaging with the damping shaft 2042 to achieve damping adjustment. The support assembly 30 is secured to the angle adjustment body 2041 via screws 2043. Mobile electronic devices such as mobile phones, iPads, laptops, and projectors can be placed on the support assembly 30.
[0052] The support assembly 30 is provided with anti-slip features, heat dissipation holes and fixing devices to prevent the mobile electronic device from shaking during the adjustment process.
[0053] It is known that the above components such as the pivot tube 201, the pivot tube 203, the fixing seat 2025, the base and the like can be made of metal, alloy or hard polymer materials.
