With the rapid development of wireless network technology and the advancement of the electronics industry, the current portable electronic products are getting smaller and smaller, but more and more functions. For example, today's mobile phones are not only making calls. In addition to sending and receiving newsletters, it also has functions such as taking photos, recording, navigating, surfing the Internet, reading e-books, watching videos, playing games, etc., so that users only need to carry one mobile phone, just like carrying multiple different types. In general, the electronic device greatly improves the user's convenience in use.

In fact, although mobile phones have added many functions, in different situations, users still need to use other auxiliary devices to properly use them. For example, when users are driving, they need to use actions at the same time. The navigation function in the phone, in addition to the use of the navigation voice instructions, the user must also watch the navigation route indication, therefore, the user is bound to be unable to put the mobile phone in the pocket, or a mobile phone with a hand-held, Dangerous behavior such as steering in the hand, so the user usually assembles a support frame on the car to place the mobile phone upright on the support frame, so that he can watch the display of the mobile phone while listening to the navigation voice indication. Generally speaking, the conventional support frame usually has an accommodating space for the mobile phone to be placed thereon. Referring to FIG. 1 , one end of the support frame 1 is provided with a positioning portion 11 (eg, a suction cup). ), which can be fixed to the vehicle body, and the other end is provided with a plurality of studs 13 which can be surrounded by each other to form an accommodating space for use. The mobile phone is placed in the accommodating space, and is subjected to the limiting effect of the studs 13, so that the mobile phone can be fixed in the accommodating space, so that the user can conveniently take the action. The mobile phone's navigation function can be used by phone or during driving.

However, as shown in FIG. 1 , the conventional support frame 1 can solve the problem that the user cannot hold the mobile phone and the steering wheel at the same time when driving, but in practice, the conventional support frame 1 still has many disadvantages. First of all, the mobile phone only relies on the limitation of each of the studs 13 and cannot be arbitrarily displaced, but there is still a slight gap between the mobile phone and each of the studs 13, so that during the driving process, due to the bumpy road surface With the swaying effect, the mobile phone will continuously collide with each of the studs 13, causing the surface of the mobile phone to be easily damaged. Secondly, since the conventional support frame 1 does not have any locking effect on the mobile phone, it is severely bumpy. During the driving process, the mobile phone is easily disengaged from the accommodating space and falls on the underside of the vehicle, causing the mobile phone to be damaged, causing the user to spend extra money to repair or purchase a new mobile phone.

Therefore, how to design a new kind of bracket device for the above shortcomings, in addition to the location of the fixed mobile phone, it is convenient to operate and use, so as to greatly increase the market competitiveness of the industry, that is, become a lot of relevant A major issue solved by the industry.

In order to clearly disclose the operation principle of the stent device 2 of the present invention, only the interlocking relationship of the aforementioned components will be described. In the seventh to seventh embodiments, the front casing is omitted to prevent excessive components from being obscured. As shown in the figures 2, 3 and 7A, when the user places the portable electronic device 3 in the recess 2111, the portable electronic device 3 can abut against the top surface of the bottom plate 231. The user can push the portable electronic device 3 while dissipating the force of the bottom plate spring 233 to displace the bottom plate 231 toward the bottom of the base body 21 (as indicated by arrow A in FIG. 7A). Before being displaced downward to a first distance, the double-sided rack 235 is also driven to be displaced downward, and at the same time, affected by the tooth portion 2351 of the double-sided rack 235, each of the one-way driving gears 271 faces in the first direction. Rotating and driving the corresponding gear 273 to rotate. In particular, the first direction refers to the one-way driving gear 271 capable of driving the rotation direction of the front gear 273. Therefore, for the two directions of the second figure In the case of the drive gear 271, the one-way drive gear 271 on the left side The first direction is clockwise, the right way first drive gear 271 counterclockwise direction, the first engagement stating. Moreover, referring to FIGS. 6A and 7A, when each of the front gears 273 rotates, the corresponding grooved disk 275 is rotated in the first direction, and each of the strikers 2773 can be in the corresponding first channel 2751. In the middle, at the same time, each of the locking racks 251 is driven by the corresponding front gear 273 and displaced upward (as indicated by arrow B in Fig. 7A).

As shown in FIGS. 2 and 7B, when the bottom plate 231 is displaced downward to exceed the first distance, each of the striker 2773 (as shown in FIG. 6A) is slid by the corresponding first channel 2751. Moving to the second channel 2753 and abutting against one end of the second channel 2753, such that the grooved disk 275 cannot rotate in the first direction, and when the locking rack 251 is displaced upward, The inclined surface 2511 (shown in FIG. 4) pushes the corresponding locking slider 255 so that each locking slider 255 can be displaced toward the central axis of the base body 21 through the corresponding through hole 2115 (eg, In the arrow C) of Figure 7B, after the user no longer pushes the portable electronic device 3, since the portable electronic device 3 and the locking sliders 255 still have a spacing, the bottom plate is received. The 233 is affected by the force of the spring 233, and the bottom plate 231 is displaced upward along with the double-sided rack 235 (such as the arrow D in FIG. 7B) until the portable electronic device 3 abuts against each of the locking sliders 255 (eg, 7C, and the bottom plate 231 will return to a position that does not exceed the first distance, so that the portable electronic device 3 is fixed to the bracket. 2 home, and can not be easily disengaged. In addition, during the upward displacement of the double-sided rack 235, the double-sided rack 235 drives the one-way driving gear 271 to rotate in the second direction. At this time, each of the one-way driving gears 271 cannot drive the corresponding front. The gear 273 is rotated such that each of the locking racks 251 is not driven to be displaced downward, so that each of the locking sliders 255 can remain in the locked state. Moreover, when the user no longer pushes the portable electronic device 3, the force of each of the locking springs 253 forces the locking racks 251 to be displaced downward, and each of the locking racks 251 is driven. Each of the front gears 273 rotates to drive the corresponding slotted disk 275 to rotate. At this time, each of the strikers 2773 is slid from one end of the second channel 2753 to the recessed portion 2753A (as shown in FIGS. 6A and 6B). Therefore, the grooved discs 275 cannot be rotated, so that the locking racks 251 can not be displaced downward, and since the distance between one end of the second channel 2753 and the recessed portion 2753A is extremely short, each The locking slider 255 can still remain in the locked state.

Referring to FIGS. 2 and 7D, when the user presses the portable electronic device 3 again, the bottom plate 231 is displaced downward along with the double-sided rack 235, the double-sided rack 235 drives the one-way drive. The gear 271 rotates to rotate the corresponding front gear 273 and the grooved disk 275. Since the striker 2773 is slipping, it is limited by the sharp portion 2753B of the second channel 2753 (as shown in Figs. 6A and 6B). Only sliding in the direction of the third channel 2755 until the striker 2773 slides into the third channel 2755, 嗣, when the user no longer presses the portable electronic device 3, each of the locks The force of the spring 253 forces the locking racks 251 to be displaced downward (as indicated by the arrow E in FIG. 7D). At this time, each of the locking racks 251 drives the front gears 273 to rotate, thereby driving the corresponding ones. The slotted disk 275 rotates so that each of the striker 2773 can slide along the third channel 2755 and slide to the first channel 2751, and again, during the downward displacement of each of the locking racks 251 Each of the locking sliders 255 is affected by the force of the corresponding slider spring 257 and faces away from the central axis of the housing body 21. The directional displacement (such as arrow F in FIG. 7D) is displaced to the accommodating space 210 via the corresponding through hole 2115 to be in a released state (as shown in FIG. 7E), and at the same time, the bottom plate 231 is subjected to each of the bottom plate springs. The force effect of the 233 also drives the portable electronic device 3 to be displaced upwards, so that the user can directly remove the portable electronic device 3.

Therefore, as shown in FIGS. 2 and 7A, with the overall structure of the bracket device 2 of the present invention, when the user wants to fix the portable electronic device 3 to the bracket device 2, only the portable electronic device is needed. The device 3 is placed in the recess 2111, and the portable electronic device 3 is pressed to displace the other end of the support module 23 downward beyond the first distance, so that the bracket device 2 can automatically lock the bracket device 2 The portable electronic device 3 prevents the portable electronic device 3 from being detached from the cradle device 2 due to vibration or shaking. Moreover, when the user wants to take out the portable electronic device 3, the portable electronic device 3 only needs to be pressed again. After the electronic device 3, the cradle device 2 automatically releases the portable electronic device 3, so that the other end of the supporting module 23 drives the portable electronic device 3 to be displaced upwards, so that the user can directly take the portable device. Electronic device 3.
