More specifically, one side surface of the pair of ear pieces 240 and the single ear piece 250 is flush with the back of the phone body 210 to facilitate the insertion of the smart phone 200.

Hereinafter, the specific structure of the external lens assembly 100 will be described.

The back plate 110 is a rectangular plate-shaped member, and a substrate (not shown) as a circuit board and various electronic components (not shown) are electrically connected to the substrate through wires. A circular penetrating portion 111 that penetrates the back plate 110 in the thickness direction is formed at a substantially central position of the back plate 110. The penetration portion 111 can ensure that the light from the lens 120 passes through the back plate 110 to the photosensitive element 230 of the smartphone 200 smoothly.

The lens 120 is used to collect the light from the illuminated object and concentrate it. The lens 120 is arranged on the front side of the back plate 110 as a side surface. In this embodiment, although the lens 120 is constituted by a zoom lens, it is not limited to this. For example, it may be constituted by a fixed focus lens. In addition, the lens 120 can perform both manual focusing and automatic focusing.

The lens 120 includes a retractable lens barrel and a plurality of lens groups (not shown) built in the lens barrel. The zooming of the lens 120 is achieved by changing the distance between a plurality of lens groups. In addition, the focusing of the lens 120 is achieved by moving at least one lens group along the direction of the optical axis. In addition, a plurality of lens groups may also include anti-vibration lenses that correct vibration caused by hand shaking.

In order to ensure the accuracy of the connection between the lens 120 and the back plate 110, the lens 120 is fixedly connected to the back plate 110, and the connection between the two is non-detachable. Further, in this embodiment, the lens 120 and the back plate 110 are formed as an integral structure.

A pair of sliding grooves 130 are provided on the back side of the back plate 110 as the other side, and are matched with a pair of ear pieces 240 of the smartphone 200 to guide the movement of the ear pieces 240. Through the matching of the pair of sliding grooves 130 and the pair of ear pieces 240, the smart phone 200 is slidably mounted on the back of the back plate 110. As a result, compared with the case where the external lens assembly is mounted on the smartphone by a clamping method, the external lens assembly 100 can be prevented from falling off from the smartphone 200, thereby improving the use safety and stability of the external lens assembly 100 And practicality.

A pair of sliding grooves 130 are provided on a pair of edges of the back surface of the back plate 110 in a manner of extending along the length direction of the back plate 110, specifically, provided at a pair of long edges of the back surface of the back plate 110. As a result, the smartphone 200 can be stored between the pair of sliding grooves 130, and the spacing between the pair of sliding grooves 130 matches the width of the mobile phone body 210 to prevent the smartphone 200 from being stored between the pair of sliding grooves 130. Shaking occurs. In addition, the thickness of the mobile phone body 210 is greater than or equal to the thickness of the sliding groove 130 to better interact with the mobile phone body 210 and the sliding groove 130 to form a limit and maintain the stability of the mobile phone body 210 between the sliding grooves 130.

In this embodiment, the pair of sliding grooves 130 does not span the entire pair of long edges, but is set to span only part of the pair of long edges, that is, the length of the sliding groove 130 is less than the length of the long edge on the back of the back plate 110 . Specifically, a pair of sliding grooves 130 are provided on one end side (lower side in FIG. 1) of the penetration portion 111.

One end of the pair of sliding grooves 130 (the lower side in FIG. 1) is for the ear piece 240 of the smartphone 200 to be inserted. Thus, the smartphone 200 can be slidably housed on the back surface of the back plate 110 from the lower side to the upper side by matching the pair of sliding grooves 130 and the pair of ear pieces 240, as shown in FIG. 1.

As shown in FIG. 5A and FIG. 5B, the sliding groove 130 includes an upright plate 131 and an opposite plate 132. The upright plate 131 is vertically fixed to the back of the back plate 110. The opposite plate 132 is formed at the top end of the upright plate 131 and is opposite to the back plate 110 in parallel.

In order to stably store the smartphone 200, a pressing mechanism 133 is provided on the side (inside) of the counter plate 132 facing the back plate 110. The pressing mechanism 133 presses the pair of ear pieces 240 of the smartphone 200 to the back of the back plate 110. As a result, it is possible to avoid looseness between the external lens assembly 100 and the smart phone 200, resulting in a change in the flange distance between the lens 120 and the smart phone 200.

In this embodiment, the pressing mechanism 133 in the sliding groove 130 is composed of an elastic piece 134. The elastic piece 134 is used to press the ear piece 240 so as to stably fix the smartphone 200 on the back plate 110. The elastic piece 134 includes a side surface 134 a opposite to the opposing plate 132 and another side surface 134 b as a pressing surface opposite to the back surface of the back plate 110.

Specifically, in this embodiment, the end of the elastic piece 134 away from the slide restricting portion 140, that is, the end toward the insertion side of the smartphone 200, is connected to the opposing plate 132. The other end of the elastic piece 134 close to the sliding restricting portion 140 is a free end, and is separated from the opposite plate 132 in a natural state. The elastic piece 134 is arranged in a way that the distance between one side 134a of the elastic piece 134 and the opposite plate 132 gradually increases from one end of the elastic piece 134 to the other end of the elastic piece 134. When the elastic piece 134 is in its natural state, the minimum distance between the other side surface 134b of the elastic piece and the back of the back plate 110 must be less than the thickness of the ear piece 240, so as to ensure that the ear piece 240 can resist the elastic piece when the smartphone 200 is inserted into the external lens assembly 100. 134 further presses.

When the ear piece 240 of the smartphone 200 is slidably inserted into the sliding groove 130, the ear piece 240 presses the other side 134b of the elastic piece 134, so that the other end of the elastic piece 134 approaches the opposite plate 132, and the elastic piece 134 is lifted to generate elastic force. As a result, the elastic piece 134 (pressing mechanism 133) presses the ear piece 240 against the back surface of the back plate 110, thereby fixing the smartphone 200 on the back plate 110 more stably.

The sliding restricting portion 140 is a restricting portion that restricts the sliding of the smartphone 200. The sliding restricting portion 140 is provided on the other end side (upper side of FIG. 1) of the pair of slide grooves 130 so as to extend in the width direction of the back plate 110. Specifically, the side provided on the back side of the back plate 110 is short. Edge (upper edge in Figure 1). In addition, the sliding restriction 140 matches the single ear piece 250 of the smartphone 200. The matching of the sliding restriction portion 140 and the single ear piece 250 can restrict the upper side sliding of the smartphone 200 with respect to the back plate 110.

A storage space S for accommodating the smartphone 200 is formed by the pair of slide grooves 130, the single slide restricting portion 140, and the back surface of the back plate 110. Since the pair of sliding grooves 130 and the single sliding restricting portion 140 are respectively provided on the pair of long edges on the back of the back plate 110 and the short edge on one side of the back of the back plate 110, almost the entire back of the back plate 110 can be used as a storage space S The sliding smartphone 200 is stored. The sliding storage action is faster, and the three-point fixation makes the connection between the back plate 110 and the smart phone 200 more stable.

As shown in FIG. 6, similar to the sliding groove 130, the sliding restriction portion 140 includes an upright plate 141 and an opposing plate 142. The upright plate 141 is vertically fixed to the back of the back plate 110. The opposite plate 142 is formed at the top end of the upright plate 141 and is opposite to the back plate 110 in parallel.

In order to stably store the smartphone 200, a pressing mechanism 143 is provided on the side (inside) of the counter plate 142 facing the back plate 110. The pressing mechanism 143 presses the single ear piece 250 of the smartphone 200 to the back of the back plate 110. As a result, it is possible to avoid looseness between the external lens assembly 100 and the smart phone 200, resulting in a change in the flange distance between the lens 120 and the smart phone 200.

As shown in FIG. 6, the pressing mechanism 143 in the sliding restricting portion 140 in this embodiment is different from the pressing mechanism 133, and the pressing mechanism 143 includes a pressing piece 144 and a spring 145. The pressing piece 144 is used to press the ear piece 250. The pressing piece 144 includes one end surface 144 a opposed to the opposed plate 142, the other end surface 144 b as a pressing surface opposed to the back surface of the back plate 110, and an inclined surface 144 c opposed to the back surface of the back plate 110. The inclined surface of the inclined surface 144c faces the other end side (the lower side in FIG. 1), that is, the insertion side of the smartphone 200. The setting of the inclined surface 144c facilitates the insertion of the ear piece 250. In the natural state of the spring 145, the minimum distance between the other end surface 144b of the pressing piece and the back of the back plate 110 must be less than the thickness of the ear piece 250, so as to ensure that the ear piece 250 can interfere when the smartphone 200 is inserted into the external lens assembly 100 It is pressed to the other end surface 144b of the pressing piece.

The spring 145 is used to connect the pressing piece 144 with the opposite plate 142. One end of the spring 145 is fixed to the bottom surface of the spring receiving hole 142 a formed in the opposed plate 142, and the other end of the spring 145 is fixed to one end surface 144 a of the pressing piece 144. As a result, the pressing piece 144 is supported by the opposing plate 142 via the spring 145.

When the spring 145 is in a natural state, that is, when the spring 145 is in an uncompressed state, the pressing piece 144 is away from the opposing plate 142.
