The two gravity center adjusting members 20 are roughly parallel with each other, and the two gravity center adjusting members 20 both are perpendicular to the driving member 10. In other words, the gravity center adjustable device 100 has an “I” shape.
In at least one exemplary embodiment, the driving member 10 is a motor.
Referring to
Each one of the two gravity center adjusting members 20 comprises a gravity center adjusting shaft 21, two weight balls 22 secured to two opposite ends of the gravity center adjusting shaft 21 respectively, and a gravity center adjusting box 23. The gravity center adjusting shaft 21 passes through the gravity center adjusting box 23, and the two weight balls 22 are outside of the gravity center adjusting box 23.
The gravity center adjusting shaft 21 comprises a rack shaft 211, and two smooth shafts 212 secured to two opposite ends of the rack shaft 211. Each one of the weight balls 22 is fixed on an end of each one of the two smooth shafts 212 away from the rack shaft 211. Teeth of the rack shaft 211 are engaged with those of the gear wheel 13, when the gear wheel 13 is rotating, the rack shaft 211 will move around along its own axial relative to the gear wheel 13.
In at least one exemplary embodiment, the two smooth shafts 212 have a same length.
Each one of the weight balls 22 comprises a first fixing hole 221. An end of a smooth shaft 212 away from the rack shaft 211 is inserted into a first fixing hole 221 of a weight ball 22. In at least one exemplary embodiment, the weight balls 22 have a same weight.
The gravity center adjusting box 23 comprises a box slot 231, and a box cover 232 covering the box slot 231.
The box slot 231 comprises a bottom wall 2311, two first side walls 2312 parallel with each other, a second side wall 2313, and a third side wall 2314 parallel with the second side wall 2313. The second side wall 2313 and the third side wall 2314 are located between the two first side walls 2312, and the two first side walls 2312 are located between the second side wall 2313 and the third side wall 2314. All of the two first side walls 2312, the second side wall 2313, and the third side wall 2314 are perpendicular to the bottom wall 2311. The box cover 232 covers a side of the box slot 231 away from the bottom wall 2311.
Each one of the two first side walls 2312 comprises a first notch 2315. The first notch 2315 is formed on a side of the first side wall 2312 away from the bottom wall 2311. A size of the first notch 2315 is equal to or slightly bigger than a cross-sectional dimension of the smooth shaft 212, thus the smooth shaft 212 can be received in the first notch 2315. Each smooth shaft 212 of a gravity center adjusting shaft 21 is slidably and rotatably received in a first notch 2315, thus the gravity center adjusting shaft 21 is supported on the two first side walls 2312 of the box slot 231, and the rack shaft 211 is inside of the box slot 231. As the smooth shaft 212 is slidably received in the first notch 2315, the gravity center adjusting shaft 21 can slide relative to the first side wall 2312, in other words, the gravity center adjusting shaft 21 can slide around relative to the gravity center adjusting box 23.
The second side wall 2313 comprises a second notch 2316. The second notch 2316 is formed on a side of the second side wall 2313 away from the bottom wall 2311. A size of the second notch 2316 is equal to or slightly bigger than a cross-sectional dimension of the transmission shaft 12, thus the transmission shaft 12 can be received in the second notch 2316. The transmission shaft 12 is rotatably received in the second notch 2316, the first end 121 of the transmission shaft 12 is outside of the box slot 231, and the second end 122 of the transmission shaft 12 is inside of the box slot 231. The gear wheel 13 coiled around the second end 122 overhangs inside of the box slot 231, and the transmission shaft 12 is perpendicular to the second side wall 2313. In at least one exemplary embodiment, the gear wheel 13 may overhang below the rack shaft 211 (shown in
In at least one exemplary embodiment, the box slot 231 further comprises at least one fixing plate 230. The fixing plate 230 is secured to the bottom side of the second side wall 2313 and/or the bottom side of the third side wall 2314. The fixing plate 230 comprises a second fixing hole 2301. The gravity center adjusting box 23 further comprises at least one fixing piece 2302. The fixing piece 2302 matches with the second fixing hole 2301 to fix box slot 231 on other member, such as a housing 301 (shown in
The box cover 232 defines at least one third fixing hole 2321. The box slot 231 defines at least one fourth fixing hole 2310 away from the bottom wall 2311. The gravity center adjusting box 23 further comprises at least one fastener 2322. The third fixing hole 2321, the fourth fixing hole 2310, and the fastener 2322 match with each other to fix the box cover 232 onto the box slot 231.
Referring to
When the gravity center of the gravity center adjustable device 100 needs to be changed, the gravity center adjustable device 100 is started, the driving main body 11 of the driving member 10 drives the two transmission shafts 12 to revolve on their own axes. The gear wheel 13 secured to each one of the two transmission shafts 12 rotates along with the transmission shaft 12. As the teeth of the rack shaft 211 are engaged with those of the gear wheel 13, the rack shaft 211 moves around along its own axial relative to the gear wheel 13, the gravity center adjusting shaft 21 will slide relative to the gravity center adjusting box 23, thus weight balls 22 move. The weight ball 22 secured at an end of the gravity center adjusting shaft 21 moves close to the gravity center adjusting box 23, and the weight ball 22 secured the other end of the gravity center adjusting shaft 21 moves away from the gravity center adjusting box 23. Thus, the gravity center of the gravity center adjustable device 100 will shift along the direction that the gravity center adjusting shaft 21 and the weight balls 22 move along.
In at least one exemplary embodiment, both of the gravity sensor 201 and the processor 202 are fixed on the driving member 10 of the gravity center adjustable device 100.
The housing 301 comprises a back plate 3011, and a middle frame 3012 perpendicular to the back plate 3011. The middle frame 3012 is an annular frame. The middle frame 3012 is formed by extending perpendicularly from a border of the back plate 3011. The gravity center self-adjusting device 200 is fixed on the back plate 3011 through the fixing piece 2302 and the second fixing hole 2301.
In at least one exemplary embodiment, the back plate 3011 is made of glass. In other exemplary embodiment, an outer surface of the back plate 3011 is attached to glass panel (not shown).
The middle frame 3012 is maybe made of metal, plastic, or other materials not easily broken.
When the electronic device 300 is falling, the electronic device 300 will have a gravity acceleration, thus the gravity center self-adjusting device 200 secured in the electronic device 300 will have a gravity acceleration. The gravity sensor 201 will sense that the electronic device 300 and the gravity center self-adjusting device 200 have a gravity acceleration, and send the information that the electronic device 300 and the gravity center self-adjusting device 200 have a gravity acceleration to the processor 202. The processor 202 will receive the information, and start the driver member 10, the driving member 10 will drive the two gravity center adjusting members 20 to adjust the gravity center of the electronic device 300, to have the gravity center of the electronic device 300 tilt to one side. This changes the angle of contact between the electronic device 300 and the ground, to ensure that the contact point of the electronic device 300 and the ground is always on the middle frame 3012, to protect the display screen 302 and the back plate 3011 from being broken.
It is to be understood, even though information and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present embodiments, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the plain meaning of the terms in which the appended claims are expressed.
