1 is a partial exploded view of an electronic device according to an embodiment of the present invention.

2 is a partial cross-sectional view showing the assembled electronic device of FIG. 1.

The connection structure of the present invention and the electronic device using the same will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 1 , an electronic device 100 according to an embodiment of the present invention is a mobile phone, which includes a housing 10 , a protective cover 20 , and a connecting structure 30 that connects the protective cover 20 to the housing 10 . The connecting structure 30 includes a holding member 40 formed at one end of the protective cover 20 and a retaining hole 50 formed in the housing 10.

The protective cover 20 includes a covering portion 21, a boss 23 formed on the covering portion 21, and the above-described holding member 40. The holding member 40 is formed at one end of the cover portion 21, and includes a latching portion 41 and a connecting portion 43 at which the two ends are respectively connected to the latching portion 41 and the cover portion 21. The radial dimension of the latching portion 41 is larger than the connecting portion. Radial dimensions of 43. In the present embodiment, the protective cover 20 is made of TPU (Thermoplastic Urethane), and the holding member 40 has elasticity. Of course, the holding member 40 can also be a separate component, which can be fixed to the covering portion 21 after being manufactured.

The housing 10 includes a side wall 11 and a cavity 12 formed in the interior of the housing 10 and communicating with the latching hole 50. The side wall 11 is provided with a slot 13. The slot 13 can be covered and closed by the cover portion 21 of the protective cover 20, which includes the bottom wall 15. The bottom wall 15 is provided with the above-mentioned holding hole 50 penetrating through the bottom wall 15. The bottom wall 15 is further provided with a socket 19, and the shape and size of the socket 19 correspond to the boss 23 of the protective cover 20.

The holding hole 50 includes a first hole portion 51, a second hole portion 52 and a communication portion 53 between the first hole portion 51 and the second hole portion 52, which are arranged in parallel and communicate with each other, wherein the first hole portion 51, The communicating portion 53 and the second hole portion 52 are both through holes, and the radial dimension of the first hole portion 51 is greater than or substantially equal to the radial dimension of the latching portion 41 of the retaining member 40, and the radial dimension of the communicating portion 53 is slightly The radial dimension of the connecting portion 43 of the holding member 40 is smaller than the radial dimension of the connecting portion 43 of the holding portion 43 of the holding member 40 and the holding portion 43 of the holding member 40. In order to ensure that the holding member 40 loaded in the second hole portion 52 can be smoothly rotated, the radial dimension of the second hole portion 52 can be slightly larger than the radial dimension of the connecting portion 43 of the holding member 40. Of course, the radial dimension of the second hole portion 52 can also be equal to or even slightly smaller than the radial dimension of the connecting portion 43, and only the holding member 40 can be rotated in the second hole portion 52.

The jack 19 is used to connect the circuit board interface (not shown) of the electronic device 100 to the outside world. It facilitates data exchange with external input or output devices, which can cooperate with the boss 23 of the protective cover 20. In this embodiment, the latching holes 50 and the insertion holes 19 are formed on opposite sides of the bottom wall 15 of the slot 13. The radial dimension of the communicating portion 53 gradually decreases from the first hole portion 51 in the direction of the second hole portion 52. small.

Referring to FIG. 2, when the electronic device 100 is assembled, first, the holding member 40 of the connecting structure 30 is inserted into the first hole portion 51 of the holding hole 50, so that the holding portion 41 of the holding member 40 extends. The inner cavity 12 of the housing 10 is inserted into the inner cavity 12 of the housing 10, and the latching portion 43 is located in the first hole portion 51. Then, the protective cover 20 is laterally dragged with a slight force to move the connecting portion 43 of the holding member 40 toward the second hole portion 52 along the communicating portion 53 until the connecting portion 43 enters the second hole portion 52. When the connecting portion 43 of the holding member 40 enters the second hole portion 52 from the communicating portion 53, since the radial dimension of the second hole portion 52 is smaller than the radial dimension of the holding portion 41 of the holding member 40, the holding member The second hole portion 52 cannot be pulled out and is caught on the casing 10. At the same time, since the communication portion 53 is smaller than the connecting portion 43, the holding member 40 does not arbitrarily slide into the first hole portion 51. Then, the boss 23 of the protective cover 20 is aligned with the insertion hole 19 of the casing 10 and the cover portion 21 of the protective cover 20 is pressed to engage the boss 23 into the insertion hole 19, at which time the cover portion 21 of the protective cover 20 is sealed. The slot 13 is assembled to the electronic device 100.

When the electronic device 100 needs to exchange data with an external input or output device, it is only necessary to apply force to the protective cover 20 to cause the boss 23 to come out of the insertion hole 19 and rotate the appropriate angle with the holding member 40 as a rotating shaft. The board interface in the jack 19.

During the loading process of the protective cover 20 of the electronic device 100, the latching portion 41 of the latching member 40 of the connecting structure 30 first passes through the sidewall 11 of the housing 10 through the first hole portion 51 of the latching hole 50. After entering the cavity 12, the holding member 40 is slid and then held in the second hole portion 52 of the holding hole 50. The operation of the process is easy and convenient, so the connecting structure 30 makes the electronic The protective cover 20 of the device 100 is easy to install. In addition, when the protective cover 20 is damaged and needs to be replaced, it is only necessary to first remove the boss 23 from the insertion hole 19, and then slide the protective cover 20 to disengage the locking hole 50 from the path opposite to the loading direction. The protective cover 20 can be easily taken out, which is very convenient.

It can be understood that the first hole portion 51, the communication portion 53 and the second hole portion 52 may not be arranged side by side, and only the first hole portion 51, the communication portion 53 and the second hole portion 52 penetrate through the side wall 11 of the casing 10. And they can communicate with each other. Moreover, the holding hole 50 may only include the first hole portion 51 and the second hole portion 52 which are in communication with each other. At this time, the radial dimension of the intersection of the first hole portion 51 and the second hole portion 52 is smaller than the holding member. The radial dimension of the connection portion 43 of 40. The holding member 40 may be non-elastic, and the side wall 13 forming the holding hole 50 may be provided to have elasticity.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
