For a further illustration to the structure of the holder 200, FIG. 3 shows an exploded view of the holder 200 of the present embodiment. Referring to FIGS. 1A, 1B and 3, the second locking part 210 is located at a front end of the holder 200, and the second locking part 210 has an assembling opening 212 and an assembling space 214 behind the assembling opening 212. An area of a projection of the assembling space 214 on a plane S (as shown in FIG. 1B) where the assembling opening 212 is located is greater than and lies over the area of the assembling opening 212. In other words, the assembling opening 212 is shrank relative to the assembling space 214, such that a displacement of the head portion 112 of the first locking part 110 parallel to an assembling direction is restricted thereby after the head portion 112 enters the assembling space 214 along the assembling direction.
More specifically, the second locking part 210 includes a first board 216 and a second board 218, wherein the first board 216 is provided with the aforementioned assembling opening 212 thereon, and the second board 218 is disposed in parallel with the first board 216 to form the assembling space 214. In addition, corresponding to the head portion 112 of the first locking part 110, a movable second decoration plate 220 is disposed at the assembling opening 212 of the second locking part 210, and a second elastic component 222 is disposed at a back side of the second decoration plate 220 so as to provide a returning force to the second decoration plate 220 in operation. In the present embodiment, the second elastic component 222 comprises a plurality of helical springs. In other embodiments, the second elastic component 222 may further be other equivalent components.
Furthermore, the second locking part 210 may further include two locating protrusions located on a side wall of the assembling space 214 for leaning and fixing the head portion 112 of the first locking part 110 when the head portion 112 enters the assembling space 214.

In the present embodiment, the holder 200 may further include a shaft 232 and a base 234, which form the holder 200 together with the second locking part 210. The shaft 232 and the base 234 are connected with each other via a joint 252, and the shaft 232 is further connected to the second locking part 210 via another joint 254, such that the position of the handheld electronic device 100 can be adjusted in three-dimensional directions after the handheld electronic device 100 is installed on the holder 200. However, the holder 200 may further include screws or other components, while the profiles and the assembling manners of those unshown components may vary with practical requirements and are not limited to the present embodiment.
FIGS. 4 through 6 illustrate an assembling process of the handheld electronic device 100 and the holder 200, wherein FIGS. 4A, 5A and 6A are schematic views of the components in the assembling process, FIGS. 4B, 5B and 6B are cross-sectional views of the components in the assembling process, and FIGS. 4C, 5C and 6C are front views of the components in the assembling process. For a clear illustration to the relative positions of the first locking part 110 and the second locking part 210 in the assembling process, FIGS. 4C, 5C and 6C omit a part of the components.
Firstly, as shown in FIGS. 4A through 4C, the head portion 112 of the first locking part 110 passes through the assembling opening 212 of the second locking part 210 along an assembling direction D1 and then enters the assembling space 214. At the same time, the second locking part 210 pushes the first decoration plate 130 and enters the accommodating space 122 at the back side 100a of the handheld electronic device 100. Meanwhile, the second decoration plate 220 is pushed by the head portion 112 and moves along the assembling direction D1 when the head portion 112 enters the assembling space 214.
Then, as shown in FIGS. 5A through 5C, the handheld electronic device 100 along with the first locking part 110 is driven to move along an engaging direction D2 parallel to the surface S, and then the head portion 112 of the first locking part 110 reaches a locking position as shown in FIG. 5B. In this step, the locating protrusions 217 lean against the head portion 112 of the first locking part 110 and fix the head portion 112 when the head portion 112 reaches the locking position. Thereby, the handheld electronic device 100 can be reliably fixed to the second locking part 210 of the holder 200 via the first locking part 110.
However, after the above steps, users may rotate the handheld electronic device 100 to meet operating requirements. Referring to FIGS. 6A through 6C, the first locking part 110 of the handheld electronic device 100 may be rotated relative to the second locking part 210 of the holder 200 along an axis Ax parallel to the assembling direction D1. Herein, the maximum rotating angle may be restricted to 90 degrees. To achieve the restriction of the rotation angle, a guiding slot 112a can be formed on the head portion 112 of the first locking part 110, while a bump 214a corresponding to the guiding slot 112a is formed on a side wall of the assembling space 214 of the second locking part 210. The bump 214a is movably installed in the guiding slot 112a. The bump 214a enters the guiding slot 112a after the head portion 112 of the first locking part 110 reaches the locking position in the assembling space 214. The first locking part 110 is adapted to rotate relative to the second locking part 210 along the axis Ax by driving the bump 214a to move from an end of the guiding slot 112a to another end of the guiding slot 112a. In other words, the translation path of the bump 214a in the guiding slot 112a can be defined by regulating the length or the profile of the guiding slot 112a, so as to adjust the range of the rotating angle between the first locking part 110 and the second locking part 210.
The assembling process of the handheld electronic device 100 and the holder 200 is illustrated above, while the handheld electronic device can be detached from the holder 200 by reversely performing the above steps. In addition to the above embodiments, the present application also provides other implementations.
For example, the holder 200 may further provide functions of charging or transmitting data to the handheld electronic device 100 except fixing the same. Referring to FIG. 2, the first decoration plate 130 has an outer surface 130a opposite to the main body 102 of the handheld electronic device 100 and an electrode contact 134 on the outer surface 130a. The electrode contact 134 is electrically connected to the main body 102 of the handheld electronic device 100.
In addition, as shown in FIG. 3, the second locking part 210 of the holder 200 has a pogo pin 240 corresponding to the above electrode contact 134. The pogo pin 240 may be electrically connected to a power source or a signal source, and the pogo pin is adapted to be contact with the electrode contact 134 after the first locking part 110 and the second locking part 210 are joined together. The base 234 of the holder 200 may be provided with a transmission port 236 and a cable 238. The cable 238 is connected between the transmission port 236 and the pogo pin 240. Herein, the transmission port 236 may be a connecting port of universal serial bus (USB) interface or other transmission interfaces, to meet requirement of data transmission or charge.
Furthermore, referring to FIGS. 2 and 3, for aligning the handheld electronic device 100 with the holder 200, the first locking part 110 and the second locking part 210 may be respectively provided with a first magnetic component 180 and a second magnetic component 280 corresponding to each other. The first magnetic component 180 and the second magnetic component 280 may be magnets. When the first locking part 110 approaches the second locking part 210, the first magnetic component 180 and the second magnetic component 280 are adapted to be attracted with each other, such that the head portion 120 of the first locking part 110 is aligned with the assembling opening 112 and enters the assembling space 114 along the assembling direction D1 as shown in FIG. 4B.
In summary, the locking assembly of the present application has simple structure and can be applied for joining the handheld electronic device and the holder, which facilitates the minimization of the size of product and provides convenience in carrying or storing. Furthermore, the assembling process applying the locking assembly can achieve high reliability, and the users can operate the locking assembly more conveniently.
