Description

Technical Field

[0001] This utility model relates to the field of electric drive hinge technology, and in particular to a bevel gear electric drive hinge. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. To improve the ease of use and intelligence of hinges, a motor drives the hinge's rocker arm to achieve automatic opening and closing.

[0003] Chinese Patent Publication No. CN203939340U discloses a utility model patent entitled "A Fully Automatic Gear Hinge Mechanism Used in a Hinged Door". The patent includes a hinge assembly, which comprises a fixed mounting plate, a movable mounting piece, and a bushing assembly. The bushing assembly includes at least one movable bushing and at least two fixed bushings. The movable bushing is fixed to the movable mounting piece, and the fixed bushings are fixed to the fixed mounting plate. The patent also includes a motor disposed outside the hinge assembly and independent of the hinge assembly. A gear is provided on the output shaft of the motor. A gear structure is fixedly connected to one of the movable bushings, and the gear structure meshes with the gear.

[0004] The aforementioned hinge mechanism comprises only a hinge assembly, a gear structure, gears, and a motor, resulting in fewer overall components and a simpler structure. Furthermore, the motor is installed independently of the hinge assembly, thus reducing the precision requirements on the motor. This contributes to the lower cost of the entire hinge mechanism. In addition, this invention only requires ensuring the gears mesh with each other during installation, enabling simple and convenient installation.

[0005] However, when the inventors implemented this device, they found the following drawbacks: the space required for the base plate using spur gear transmission is large, which affects the load-bearing capacity of the base plate, and spur gears may reduce torque. Utility Model Content

A driving helical gear is provided on the output shaft of the drive motor, and a driven helical gear is provided on the outer surface of the swing arm drive shaft. Power relay is achieved by meshing the driving helical gear and the driven helical gear through a power relay component. The contact area between the helical gears is much larger than that of the spur gears, which improves the stability of meshing and the strength of the contact position. Moreover, the inclined contact allows the two gears to be closer together, achieving the effects of reducing the space occupied by the base plate, improving the transmission capacity, and improving the stability of torque transmission between gears.

[0045] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0046] As described in the background section, using a spur gear transmission base plate requires a large space, which affects the load-bearing capacity of the base plate, and spur gears may reduce torque.

[0047] To solve this technical problem, this utility model provides a bevel gear electric drive hinge, which is used for the hinge of objects.

[0048] For details, please refer to Figure 1-4 and Figure 7-8 The bevel gear electric drive hinge specifically includes:

[0049] A first mounting base 1 and a second mounting base 2 are connected by a connecting swing arm 3;

[0050] The drive mechanism 4 includes a drive motor 401, a power relay 404, and a swing arm drive shaft 405. The drive motor 401 is located on the back of the first mounting base 1. The drive motor 401 is a single-output head or a double-output head. A motor support frame 402 is mounted on the drive motor 401. A drive helical gear 403 is provided at the output end of the drive motor 401. The drive helical gear 403 can be located at one end or both ends of the drive motor 401 and is connected through a reducer.

[0051] The swing arm drive shaft 405 is vertically disposed inside the first mounting base 1. The outer surface of the swing arm drive shaft 405 is provided with a driven helical gear 406. The number of driven helical gears 406 is matched with the number and position of the drive helical gears 403.

[0052] The power relay 404 is disposed between the driving helical gear 403 and the driven helical gear 406, and meshes with the driving helical gear 403 and the driven helical gear 406 respectively;

[0053] The swing arm drive shaft 405 is fixedly connected to one end of the swing arm 3.

[0054] The bevel gear electric drive hinge provided by this utility model features a driving helical gear 403 on the output shaft of the drive motor 401 and a driven helical gear 406 on the outer surface of the swing arm drive shaft 405. Power relay is achieved through the meshing of the driving helical gear 403 and the driven helical gear 406 via a power relay component 404. The contact area between the helical gears is much larger than that of the spur gears, improving the stability of meshing and the strength of the contact position. Furthermore, the inclined contact surface allows the two gears to be closer together, reducing the space occupied by the base plate, increasing transmission capacity, and improving the stability of torque transmission between the gears. When the driving helical gears 403 are symmetrically distributed at both ends of the drive motor 401, a dual-drive structure is formed, ensuring consistent force on the upper and lower surfaces of the swing arm drive shaft 405, further enhancing stability. Additionally, each individual helical gear experiences less force and has a longer service life.

[0055] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0056] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0057] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0058] Example 1

[0059] Please refer to Figure 1-3 and Figure 7-8 A bevel gear electrically driven hinge includes a first mounting base 1, a second mounting base 2, and a drive mechanism 4. A connecting arm 3 is connected between the first mounting base 1 and the second mounting base 2. When driven by power, the first mounting base 1 and the second mounting base 2 rotate about the connecting arm 3 as a pivot.

[0060] The drive mechanism 4 includes a drive motor 401, a power relay 404, and a swing arm drive shaft 405. The drive motor 401 is the power output source, driving the power relay 404 to rotate the swing arm drive shaft 405, thereby causing the connected swing arm 3 to rotate and the second mounting base 2 to rotate. Specifically, the drive motor 401 is located on the back of the first mounting base 1, and the drive motor 401 can be a single-output head or a dual-output head. The drive motor 401 is either a central-axis DC geared motor or an off-axis DC geared motor, generating torque when energized. A motor support frame 402 is mounted on the drive motor 401 to support it and fix its position. A drive helical gear 403 is provided at the output end of the drive motor 401; when the drive motor 401 generates power, the power drives the drive helical gear 403 to rotate. The drive helical gear 403 can be set at one or both ends of the drive motor 401 and connected through a reducer to form a dual-drive structure, which can further improve stability and service life.

[0061] The swing arm drive shaft 405 is vertically disposed inside the first mounting base 1. A driven helical gear 406 is disposed on the outer surface of the swing arm drive shaft 405. The number and position of the driven helical gears 406 are matched with the number and position of the drive helical gears 403. That is, a single drive is equipped with a single driven helical gear 406, and a dual drive is equipped with two driven helical gears 406. A power relay 404 is disposed between the drive helical gears 403 and the driven helical gears 406, and meshes with both. At this time, the rotating drive helical gear 403 drives the power relay 404 to rotate by meshing with it. The power is relayed through the power relay 404 and transmitted to the driven helical gears 406, thereby driving the swing arm drive shaft 405 to rotate. The swing arm drive shaft 405 is fixedly connected to one end of the connecting swing arm 3. The rotating swing arm drive shaft 405 then drives the connecting swing arm 3 to rotate, thereby driving the first mounting base 1 to rotate and realize the opening and closing of the hinge.

[0062] Please refer to Figure 4-6 The power relay component 404 includes a shaft extending through the back of the first mounting base 1 and relay helical gears symmetrically mounted on both sides of the shaft. The shaft supports the two helical gears and is rotatable. The two relay helical gears are located outside and inside the first mounting base 1, respectively, and mesh with a driving helical gear 403 and a driven helical gear 406. When one helical gear is driven, it drives the other helical gear to rotate via the shaft, thus achieving power relay transmission.

[0063] To improve connection stability and reduce space occupation, hinge arms 4051 are symmetrically arranged at both ends of the outer surface of the swing arm drive shaft 405. One end of the connecting swing arm 3 is located between the two hinge arms 4051 and connected to them. When the swing arm drive shaft 405 rotates, it drives one end of the connecting swing arm 3 to rotate through the hinge arms 4051. Connecting shafts 4052 are provided at the axis of each end of the swing arm drive shaft 405, and the diameter of the connecting shafts 4052 is smaller than the diameter of the swing arm drive shaft 405. The connecting shafts 4052 are movably connected to both ends of the inner wall of the first mounting base 1, allowing the swing arm drive shaft 405 to rotate around the connecting shafts 4052. A driven helical gear 406 is arranged on one or both connecting shafts 4052, and the diameter of the driven helical gear 406 does not exceed the diameter of the swing arm drive shaft 405, thereby reducing the space occupied by the driven helical gear 406.

[0064] An auxiliary bearing is provided at the connection between the connecting shaft 4052 and the first mounting base 1. By sleeved on the upper end of the connecting shaft 4052, the friction between the connecting shaft 4052 and the first mounting base 1 can be effectively reduced, thereby improving the sensitivity of the swing arm drive shaft 405 rotation.

[0065] Example 2

[0066] The bevel gear electric drive hinge provided in Embodiment 1 is further optimized, specifically, as follows: Figure 4 As shown, the motor support frame 402 is detachably mounted on the back of the first mounting base 1, and the motor support frame 402 is an arc-shaped structure or two arc-shaped structures with openings facing each other.

[0067] The above structural design allows for adjustment of the installation position of the drive motor 401, and both sides of the bow-shaped motor support frame 402 can be used for fixing, reducing the positional requirements during installation. When the motor support frame 402 is configured with two bow-shaped openings facing each other, it can support the drive helical gears 403 at both ends of the drive motor 401 respectively, improving stability.

[0068] Example 3

[0069] The bevel gear electric drive hinge provided in Embodiment 1 or 2 is further optimized, such as... Figure 1-3 As shown, an electrical control box 407 is mounted on the side of the motor support frame 402. A power supply device and an interactive device are installed inside the electrical control box 407. The power supply device and the interactive device are interconnected, and the power supply device is electrically connected to the drive motor 401. Therefore, the power supply device's power supply status is controlled via the interactive device, thereby controlling the drive motor 401. The power supply device can be a power module connected to an external power source or a rechargeable lithium battery, etc., used for storing and transmitting electrical energy.

[0070] Specifically, the interactive device is one or a combination of NFC sensing devices, wireless remote sensing devices, or Bluetooth devices, thereby enabling card swiping, wireless remote control, and Bluetooth control, improving the ease of use of the device.

[0071] To enhance the device's protection, a protective cover 5 is provided on the back of the first mounting base 1. The protective cover 5 covers both the electrical control box 407 and the drive motor 401. Furthermore, to improve signal penetration, the protective cover 5 is made of unshielded material.

[0072] Example 4

[0073] The bevel gear electric drive hinges provided in the above embodiments are further optimized, such as... Figure 5 , Figure 6 As shown, the first mounting base 1 includes a mounting plate 101. A swing arm mounting base 102 is bolted to the interior of the mounting plate 101. During maintenance and installation, the swing arm mounting base 102 can be installed and removed independently, improving ease of use. A motor support frame 402 is mounted on the back of the swing arm mounting base 102, and a swing arm drive shaft 405 is mounted inside the swing arm mounting base 102. When the swing arm mounting base 102 is moved, the drive motor 401, power relay 404, and swing arm drive shaft 405 move with the swing arm mounting base 102, maintaining constant engagement and preventing power transmission interruption due to the movement of the swing arm mounting base 102.

[0074] Example 5

[0075] The bevel gear electric drive hinges provided in the above embodiments are further optimized, such as... Figure 9 As shown, the motor support frame 402 is horizontally mounted on the side of the electrical control box 407. The drive motor 401 is installed in the motor support frame 402. The end of the drive motor 401 is engaged with a steering gear 408. The steering gear 408 engages with the power relay 404 to change the direction of power transmission, thereby driving the swing arm drive shaft 405 to rotate. Compared with a dual-head drive motor 401, this design saves more space and is suitable for use in smaller hinges.

[0076] The bevel gear electric drive hinge provided by this utility model is used as follows:

[0077] The power supply device sends an interactive signal to the interactive device inside the control box 407 via an NFC device or a wireless control device. The power supply device controls the drive motor 401 according to the interactive signal to drive the drive motor 401 to work. When the drive motor 401 outputs power, the power is transmitted to the power relay 404 through the drive helical gear 403 set at the output end of the drive motor 401. The power relay 404 changes the direction of the power and transmits it to the driven helical gear 406. The driven helical gear 406 drives the swing arm drive shaft 405 to rotate according to the predetermined requirements. The rotating swing arm drive shaft 405 drives the connecting swing arm 3 to rotate through the hinge arm 4051, thereby driving the second mounting base 2 to rotate and realize the opening and closing of the hinge.
