1 to 6, a vehicle smartphone holder according to an embodiment of the present invention includes a main body 10, a first arm to a fourth arm 20, a pinion part 30, a pressure extension member 40, It may include a locking member 50 and the like.

The main body 10 is composed of a front cover 11 on which the rear of the smartphone is seated and a rear cover 13 that is assembled with the front cover 11 to form an accommodation space therein. When the front cover 11 and the rear cover 13 are assembled, they are fixedly coupled using fastening means such as bolts. Meanwhile, the main body 10 according to an embodiment may be provided with a fixing part (not shown) for fixing any part of a cable or a connector (c-type, 5-pin, etc.) among charging cables used in a smartphone. . In addition, the main body 10 may further include a wireless charging module (not shown) for charging a smartphone. However, since the fixing part and the wireless charging module can be designed in different forms by employing commercially available components or by known techniques, detailed descriptions will be omitted below.

On the inner side of the rear cover 13, a receiving groove is formed in which the pressure extension member 40, the pinion part 30, and the like are accommodated. Meanwhile, a rib structure may be formed on the bottom surface of the receiving groove to increase rigidity against impact or the like. In addition, a first groove in which the lower end of the pinion part 30 is accommodated is formed in the receiving groove so that the pinion part 30 is axially rotatable. In addition, a fixing protrusion for fixing one end of the second spring 44 to be described later may be further formed on one side of the receiving groove.

The front cover 11 may further include an inner cover 60 coupled to the inner side thereof. In addition, a charging pad unit (not shown) for wireless charging may be installed between the front cover 11 and the inner cover 60. In this case, a guide groove 66 for guiding the reciprocating movement of the first to fourth arms 20 in the diagonal direction of the main body 10 may be formed in the inner cover 60. In addition, a guide protrusion 68 for assisting the reciprocating movement of the first to fourth arms 20 may be further formed in the guide groove 66.

In addition, an anti-slip pad formed of materials such as general rubber, natural rubber, silicone material, urethane material, and NBR material may be further attached to the outer surface of the front cover 11 to prevent slipping of the mounted smartphone. have.

The first to fourth arms 20 are disposed on each corner side of the main body 10 and operate in conjunction with each other, and a first rack portion 25 is formed on one side thereof. Specifically, the first arm to the fourth arm 20 is coupled to the receiving holder 22 for fixing the smartphone by receiving each corner of the smartphone, the receiving holder 22, and a first rack portion 25 on one side It includes a rod plate 24 to be formed. In addition, a guide hole 26 may be formed in the first arm to fourth arm 20 to guide the first arm to fourth arm 20 to reciprocate in a diagonal direction of the body 10. Specifically, the guide hole 26 may have a rectangular oval shape formed in the rod plate 24 in the extending direction of the rod plate 24. The first to fourth arms 20 may be assembled such that the rod plate 24 is disposed in the guide groove 66 and the guide hole 26 is fitted to the guide protrusion 68.

The pinion portion 30 is engaged with the first rack portion 25, respectively, and extends or contracts the first to fourth arms 20 through axial rotation. The pinion portion 30 rotates in one direction (counterclockwise in the case of one embodiment) when the pressure elongation member 40 moves linearly toward the inside of the main body 10 by the user's pressure. Meanwhile, an elastic member that is elastically deformed in the axial direction of the pinion part 30 may be disposed at the lower end of the pinion part 30. The elastic member may be, for example, the first spring 32. When the pressing protrusion 52 to be described later is pressed, the pinion unit 30 is also lowered by pressing, and when the pressing state is released, the pinion unit 30 returns to its original position by the elastic restoring force of the first spring 32. I can.

The pressure extension member 40 has a second rack portion 42 that engages with the pinion portion 30 on one side, and is coupled to the body 10 so that the other side is exposed to the outside of the body 10, and is pressed by the user. When linearly moved to the inside of the main body 10, the pinion part 30 is rotated to elongate the first to fourth arms 20. When the pressure elongation member 40 is pressed inward from both sides, the first arm to the fourth arm 20 are opened in all directions.

This, the pressure elongation member 40 has a rod shape as a whole, and consists of a pair that moves in opposite directions to each other. According to an embodiment, the user may press the pressure extension member 40 using two fingers including a thumb. In this case, a concave surface including a protrusion may be formed at the other end of the pressure elongation member 40 to increase the gripping force of the finger when it is pressed and to enable a stable operation.

The elastic restoring force acts on the pressure elongation member 40 in proportion to the degree of pressure. To this end, a second spring 44 connecting the pressure extension member 40 and the above-described fixing protrusion may be used. For example, when the pressure elongation member 40 moves inward by pressing, the length of the second spring 44 increases, thereby generating an elastic restoring force proportional thereto.

On the other hand, the pressure elongation member 40 is each engaged with the pinion portion 30 through the second rack portion 42, and the pair of pressure elongation members 40 are not symmetrical, but centered on the pinion portion 30 It has a shape and structure that are symmetrical to each other.

A locking member 50 may be coupled to the upper surface of the pinion unit 30 to block or release the pressure extension member 40 from linear movement in the direction in which the first to fourth arms 20 are contracted. When the pressing member 40 is pressed, the locking member 50 prevents the pressing member 40 from moving in the opposite direction to the direction in which the pressing member 40 is pressed despite the action of the elastic restoring force by the second spring 44. .

To this end, the locking member 50 according to an embodiment includes a pressing protrusion 52 protruding vertically upward in the center of one surface, and a first locking part 54 in which a plurality of the pressing protrusions 52 are continuously arranged in a circle around the circumference of the pressing protrusion 52. ) Can be included. Meanwhile, the first engaging portion 54 includes a screw thread 55 having an asymmetric shape. Specifically, the thread 55 is made of an inclined surface 56 and a locking surface 57 adjacent to the inclined surface 56 and formed in a vertical direction. On the other hand, the inclined surface 56 is formed extending in the radial direction based on the pressing protrusion 52.

The pressing protrusion 52 is exposed to the outside of the main body 10 through the front cover 11. To this end, a through hole 12 through which the pressing protrusion 52 is exposed is formed in the front cover 11. In addition, the front cover 11 communicates with the through hole 12, and when the locking member 50 is non-continuously engaged, a constraining groove 16 may be formed to restrict the rotation of the locking member 50. Alternatively, an inner cover 60 communicating with the through hole 12 may be coupled to the inside of the front cover 11. Specifically, the inner cover 60 communicates with the through-hole 12, and when the locking member 50 is non-continuously engaged, a constraining groove 16 for restricting the rotation of the locking member 50 may be formed.

A second locking portion 18 meshed with the first locking portion 54 may be formed in the constraining groove 16. Here, the second locking portion 18 has a shape corresponding to the first locking portion 54. That is, the second engaging portion 18 includes a plurality of asymmetrical shaped threads that are continuously arranged in a circular shape around the bottom surface of the constraining groove 16. In addition, the thread is formed of an inclined surface and a locking surface adjacent to the inclined surface and formed in a vertical direction in the same manner as the first locking portion 54.

Next, it looks at the operation of the smartphone holder for a vehicle according to an embodiment of the present invention. The user may first press the pressure extension member 40 to elongate the first to fourth arms 20 in the radial direction. In this process, the pinion unit 30 according to an exemplary embodiment rotates in a counterclockwise direction and performs repetitive elevating movements. In this case, the pinion portion 30 is positioned at the highest point in the engagement position where the first and second engaging portions 54 and 18 are periodically repeated. And, in spite of the elastic restoring force due to the second spring 44, the pinion portion 30 at the engaging position is fixed by engaging engagement.

When the pressing and extending member 40 is further pressed in the engaging position, the first engaging portion 54 and the second engaging portion 18 are separated from the engaging position, and the pinion portion 30 makes a downward motion. When the pressure elongation member 40 is further pressed, the pinion part 30 is positioned at the highest point by the elastic restoring force of the first spring 32 as it is brought into the engagement position again, and is fixed by the engaging engagement. In this way, the user can elongate the first to fourth arms 20 as much as desired and then fix it at the position. On the other hand, depending on the repetition of the engagement and release, for example, a clicking sound may occur.

Then, the user causes at least any two corners of the smartphone to be inserted into each of the receiving holders 22 of the first to fourth arms 20. Then, the user presses the pressing protrusion 52 exposed through the front cover 11 using the rear of the smartphone. When the pressing protrusion 52 is pressed, the first spring 32 is compressed and the pinion part 30 moves downward. At this time, the elastic restoring force by the second spring 44 acting on the pressing and elongating member 40 is the first to interlock with the pinion part 30 while simultaneously rotating the pinion part 30 in a clockwise direction. The arm to the fourth arm 20 is contracted. At the same time, the pinion portion 30 causes the pressure elongation member 40 engaged with the pinion portion 30 to linearly move to the outside of the main body 10 in an instant. As a result, each corner of the smartphone is fixed by the first to fourth arms 20, and the user's smartphone can be stably mounted on the main body 10.

In this way, the smartphone holder for a vehicle according to an embodiment can easily mount and detach the smartphone by a simple operation of the user. In addition, by providing a strong fixing function to the smartphone, it is possible to provide high reliability even in the operation of a vehicle such as a motorcycle with a lot of vibration or shock.

In the above, preferred embodiments of the present invention have been exemplarily described, but the scope of the present invention is not limited to such specific embodiments, and can be appropriately changed within the scope described in the claims.
