Technical Field

[0001] The invention relates to a hub for electronic equipment, in particular to a rising and translating synchronous hub. Background Art

[0002] A hinge, also known as a damping hinge or a damping shaft core, is a connecting element that can provide mutual rotation function. It is mainly used between rotating parts and a base. At present, it is widely used in various digital products and electronic devices, such as laptops. The mutual rotation function of the hinge can realize the opening and closing function between the base and the display screen of the laptop to adjust the required angle of the laptop relative to the human body.

[0003] Taking a laptop computer as an example, the hinge is usually installed at the edge of the base and the display screen. However, with the thinning and personalization of laptop computers, the display screen of some laptop computers needs to be installed in the middle of the base. Here, the base includes front and rear parts of different thicknesses, with a step between the front and rear parts. The display screen is installed on the thinner front part, and the total thickness of the display screen and the front part is the same as that of the rear part. At this time, when the display screen is opened, the display screen needs to have the function of rising and translating synchronously, that is, the LCD will move forward and upward at the same time. Patent document CN201220093564.0 discloses a hinge device with simultaneous translation and rotation functions and a flip-top electronic device thereof. Although the hinge device has the function of simultaneous translation and rotation, its structure and technical principle are very complicated. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to more clearly understand the technical content of the present invention, the following embodiments are given in detail, the purpose of which is only to better understand the content of the present invention but not to limit the protection scope of the present invention.

The second gear is sleeved on the second shaft core and rotates synchronously with the second shaft core. The two connecting pieces are clamped at the front and rear ends of the first gear and the second gear at the same time and are rotatably sleeved on the first shaft core and the second shaft core at the same time. The first shaft core and the second shaft core are both rotatably inserted into the two guide grooves, so that the first gear, the second gear and the two connecting pieces fall into the assembly space, and the first gear is meshed with the rack for transmission, and the second gear is meshed with the first gear for transmission.

[0022] In the above structure, the function of translation is realized by the meshing transmission of the first gear set on the first shaft core and the rack set on the bottom plate of the support frame. At the same time, the function of the second gear relative to the first gear to make a circular motion is realized by the meshing transmission of the second gear set on the second shaft core and the first gear. In this way, the second gear is simultaneously performing an ascending and translating motion relative to the support frame, thereby realizing the function of synchronous ascending and translating of the hub. Compared with the structure in the prior art, the present invention simplifies the structure, reduces the number of parts, achieves the purpose of reducing production costs, and runs very smoothly. Among them, the guide groove on the mounting plate of the support frame is composed of a horizontal part and an arc-shaped ascending part. The horizontal part can provide a guiding function for horizontal movement for the first shaft core and the first gear, and the arc-shaped ascending part can provide a guiding function for circular movement for the second shaft core and the second gear. In this way, when the electronic device using the hub of the present invention, such as a laptop computer, opens the display screen (LCD), the LCD will move forward and upward at the same time, thereby avoiding the interference of the steps of the base.

[0023] In the above structure, the two connecting pieces are clamped at the front and rear ends of the first gear and the second gear at the same time and are rotatably sleeved on the first shaft core and the second shaft core at the same time to fix the relative positions of the two gears. The sizes of the first gear and the second gear can be set according to the angle to be avoided. For example, the second gear is designed as a small gear and the first gear is designed as a large gear. In this way, the angle of rotation of the second gear around the first gear can be increased.

[0024] In the above structure, the first gear and the second gear are meshed for transmission, and the first gear and the rack are meshed for transmission. Figure 1 The example shows that the first gear and the second gear are spur gears, and the rack is a spur rack, but it is not limited to this. In other embodiments, the rack can also be a helical rack, and correspondingly, the first gear and the second gear can be helical gears.

[0025] In the above structure, the synchronous rotation of the first shaft core and the first gear and the synchronous rotation of the second shaft core and the second gear can adopt a non-circular shaft core design, so that the gear can slide on the shaft core but cannot rotate in the circumferential direction.

[0026] Preferably, a first stopper 51 is formed at one end of the first shaft core. When the first shaft core rotates and passes through the two guide grooves, one end of the first shaft core is locked by a first torque assembly 80 abutting against the outside of one mounting plate, and the first stopper abuts against the outside of the other mounting plate. Here, the first torque assembly cooperates with the first stopper to provide a rotational torque for the rotation of the first shaft core relative to the two guide grooves, so that the first shaft core can slide and rotate along the guide grooves, thereby realizing the function of the first gear performing linear motion in the horizontal portion of the guide groove.

In this way, the first torque assembly composed of the first nut, the first washers and the first butterfly springs can provide the first shaft core with a rotational torque and a tight fit positioning function. However, the method of providing torque is not limited to this. In other embodiments, a wrapping torque method can also be used.

[0028] Preferably, a second stopper 61 is formed in the middle of the second axis core, and a locking part 62 is formed at one end of the second axis core. When the second axis core rotates and passes through the two guide grooves, the other end of the second axis core is locked by a second torque component 90 that is abutted against the outside of one of the mounting plates, and the second stopper is abutted against the outside of the other mounting plate. Here, the second torque component cooperates with the second stopper to provide rotational torque for the rotation of the second axis core relative to the two guide grooves, so that the second axis core can slide along the guide grooves and can rotate, thereby realizing the function of the second gear making a circular motion around the first gear. The locking part is used to connect the display of the electronic device, and the support frame is used to connect the base of the electronic device, so that when the display screen of the electronic device is opened, the LCD will move forward and upward at the same time.

[0029] Preferably, the second torque assembly includes a plurality of second washers 91, a plurality of second butterfly springs 92 and a second nut 93, the second nut is threadedly connected to the second shaft core, and the second washers and the second butterfly springs are locked to the outside of the mounting plate. In this way, the torque assembly composed of the second nut, the second washers and the second butterfly springs can provide the second shaft core with a rotational torque and a tight fit positioning function. However, the method of providing torque is not limited to this. In other embodiments, a wrapping torque method can also be used.

[0030] In the above structure, the rack and the base plate can be installed separately or integrally. Preferably, the rack and the base plate are integrally formed. In specific implementation, the support frame and the rack can be integrally formed using MIM technology. The support frame and the rack are integrally formed, which can reduce the number of assembly steps.

[0031] Preferably, the support frame includes a first bracket and a second bracket, the first bracket includes the bottom plate and a mounting plate formed on the bottom plate, the second bracket includes another mounting plate and a first protrusion 13 and a second protrusion 14 formed on the outer side and the inner side of the bottom end of the mounting plate, and the first protrusion and the second protrusion are locked to the bottom plate by fasteners.
