Description

Mobile device holder for vehicle {MOBILE DEVICE HOLDER FOR VEHICLE}

The present invention relates to a mobile device holder for a vehicle used to mount a mobile device in a vehicle.

Vehicles and mobile devices (especially mobile phones, later referred to as mobile phones, but collectively referred to as mobile devices) have become necessities of modern people. Therefore, it is common for the driver of the vehicle to drive the vehicle while carrying a mobile phone. In addition, there is a trend that the vehicle and the mobile phone are implemented to be mutually linked so that calls using the mobile phone or navigation information can be conveniently used. Accordingly, in line with such a trend, various technologies for mounting a mobile phone in a vehicle have begun to appear.

However, the size of the mobile phone may be changed by, for example, changing the mobile phone carried by the driver. In order to automatically solve this problem, Korean Patent Laid-Open Patent Publication No. 10-2013-0115313 (hereinafter referred to as 'prior art') records the clamping position and open position of the clamping jaws to mount a specific mobile phone, We propose a technology that automatically responds to the size of the mobile phone in a way that repeats the same memory to hold the phone so that the driver can hold the mobile phone.

Meanwhile, in recent years, various mobile phone manufacturers, including Samsung Electronics and Xiaomi, manufacture foldable phones so that the width of the mobile phone can be greatly changed. Accordingly, it is expected that a structure in which a mobile phone holder for a vehicle can be implemented with a variable gripping width will be sought. In this way, when a mobile phone of one type is implemented to have a variable width, if the prior art is to be applied, the inconvenience of re-setting and remembering the clamping position every time the variable width is changed occurs frequently, which is inconvenient to use In addition, it is impossible to mount a mobile phone with a large variable width in a wide state due to the limitation of the gripping width of the cradle.

The present invention is capable of properly gripping a mobile phone without having to memorize a separate gripping position, and furthermore, can automatically grip the mobile phone in response to the variable size with a simple operation when the size of the mobile phone can be changed. It was created out of concerns about technology.

According to the present invention, there are the following effects.

First, since there is no need to memorize the gripping position, it is possible to eliminate the error due to the conversion correspondence between the gap between the gripping members and the number of rotations of the motor or the rotation time of the motor.

Second, when the size of the mobile phone can be changed, it can be automatically gripped in response to the changed size with a simple operation, and even when gripped with a narrow width, the gap between the gripping members can be narrowed accordingly. Therefore, the operation time is shortened, and there is convenience in use.

Third, even when the width is greatly changed like a foldable phone, the usability of the product can be increased because it has a structure in which the gap between both gripping members is widened as much as possible.

Fourth, it is possible to maximize the variable width between both gripping members by having a structure that converts the rotational force of the rotor into linear movement force of both gripping members by applying a link and transmits it.

1 is a perspective view of a mobile phone holder 100 for a vehicle (hereinafter abbreviated as 'cradle') according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the holder 100 of FIG. 1 .

With reference to FIGS. 1 and 2 , the main components of the cradle 100 according to the present embodiment will be described.

The holder 100 according to the present embodiment includes a first gripping member 110 , a second gripping member 120 , a moving force generating source 130 , a power transmitter 140 , a guide member 150 , and a support member 160 . ), a controller 170 and an interval determiner 180 .

The first gripping member 120 is provided so that it can return after moving in the left direction as in the excerpt of FIG. 3 , and the first gripping end 111 and the pair of first guide rods 112a and 112b include

The first gripping end 111 grips or releases the left edge of the mobile phone according to its position.

A pair of first guide rods (112a, 112b) is provided so as to make a linear movement when the first gripping member 120 moves in the left direction or returns to the right direction from the first gripping end 111. stretched long

The second gripping member 120 faces the first gripping member 110 , and is provided to be able to return after moving in the right direction. The second gripping member 120 also includes a second gripping end 121 and a pair of second guide rods 122a and 122b as in the excerpt of FIG. 4 .

The second gripping end 121 grips or releases the right end of the mobile phone according to its position.

A pair of second guide rods (122a, 122b) are provided so as to make a linear movement when the second gripping member 120 moves in the right direction or returns to the left, from the second gripping end 121 to the left. stretched long

The moving force generating source 130 generates a moving force that allows the first holding member 110 and the second holding member 120 to move in association with each other. For this purpose, as referenced in FIG. 5 , the moving force generating source 130 may preferably include a motor M capable of forward and reverse rotation, and transfer the driving force of the motor M to the rotational force of the rotating shaft S. It has various gears (G1 to G4) for doing so. Of course, if the thickness of the cradle 100 is not considered, it may be sufficiently considered that the motor M is implemented to directly input power to the rotation shaft S.

The power transmitter 140 transmits the movement force generated by the movement force generating source 130 to the first gripping member 110 and the second gripping member 120 , thereby providing the first gripping member 110 and the second gripping member. 120 so that they can be moved in conjunction with each other. To this end, the power transmitter 140 includes a rotor 141 , a first link 142 and a second link 143 as shown in the excerpt of FIG. 6 .

The rotor 141 has an approximately elongated shape in the left and right direction when the distance between the both gripping members 110 and 120 is minimized, and is coupled to the rotation shaft S through the coupling hole H at the center of the rotation shaft ( It rotates in conjunction with the rotation of S).

The first link 142 has an inner side hinged to one end of the rotor 141 , and an outer side hinged to an approximately right portion of the upper first guide rod 112a of the first gripping member 110 .

The second link 143 has an inner side hinged to the other end of the rotor 141 , and an outer side hinged to the left side of the lower second guide rod 122b of the second gripping member 120 . .

The first link 142 and the second link 143 above function as a transmission portion for transmitting the rotational force of the rotor 141 to the first holding member and the second holding member. And the first link 142 and the second link 143 is a conversion part for converting the rotational motion of the rotor 141 together with the guide member 150 to be described later into the linear motion of the first holding member and the second holding member. also functions as

The guide member 150 has four guide grooves (GG ₁ to GG ₄ ) into which the first guide rods 112a, 112b and the second guide rods 122a, 122b are inserted as shown in the excerpt of FIG. have Therefore, when the first gripping member 110 and the second gripping member 120 move, the first guide rods 112a, 112b and the second guide rods 122a, 122b are in the guide grooves GG ₁ to GG ₄ ). Since it is guided in the inserted state, the movement of the first gripping member 110 and the second gripping member 120 may be made in a straight line.

The support member 160 supports the hem of the mobile phone MP held therebetween or gripped by the first gripping member 110 and the second gripping member 120 as in the reference diagram of FIG. 8 .

The controller 170 controls the movement of the first gripping member 110 and the second gripping member 120 and the amount of movement thereof. To this end, the controller 170 includes a sensing unit 171 , a determining unit 172 , and a control unit 173 as shown in the configuration diagram of FIG. 9 .

The sensing means 171 senses the load amount (more precisely, the load amount of the motor) of the movement force generating source 130 through the current value.

The determination means 172 determines whether the amount of load sensed by the detection means 171 exceeds a preset set value.

The control means 173 stops the operation of the movement force generating source 130 when it is determined by the determination means 172 that the load amount of the movement force generating source 130 exceeds a set value.

The spacing determiner 180 ultimately limits the movement of the first gripping member 110 or the second gripping member 120 or releases the restriction, thereby first opening as in FIGS. 10 (a) and (b). The interval D1 and the second opening interval D2 are determined. Here, the second opening distance D2 is wider than the first opening distance D1. In addition, the first gap D1 and the second gap D2 have a length sufficient to prevent interference when the user puts the mobile phone MP on the support member 160 . To this end, the interval determiner 180 may include a stopper 181 and an operation switch 182 as shown in the excerpt of FIG. 11 .

The stopper 181 in this embodiment limits the rotation of the rotor 141 or releases the restriction, thereby ultimately restricting or releasing the movement of the first holding member 110 and the second holding member 120. . That is, according to the position of the stopper 181 in the process of moving so that the distance between the first holding member 110 and the second holding member 120 is widened as in FIGS. 12 (a) and (b), the rotor ( The rotation of the 141 is restricted or the restriction is released, and accordingly, the movement of the first holding member 110 and the second holding member 120 interlocking therewith is restricted or the restriction is released. Of course, in this embodiment, the stopper 181 is implemented to limit the rotation of the rotor 141 or to release the restriction, but depending on the implementation, the movement of the first link 142 or the second link 143 is It may be considered to be implemented to limit or release the restriction, and furthermore, it may be sufficiently considered to be implemented to directly restrict or release the restriction of the movement of the first holding member 110 or the second holding member 120 directly. can

Meanwhile, FIG. 13 shows another example of the interval determiner 180 .

According to the interval determiner 180 of FIG. 13, when the rotor 141 rotates clockwise as in (a), the stopper 181 restricts the rotation of the rotor 141, but the rotor 141 When is rotated counterclockwise, the stopper 181 rotates clockwise by the force applied by the rotor 141 as in (b) and (c), so that the rotor 141 rotates counterclockwise. It can be rotated continuously. Of course, when the interference with the rotor 141 is removed, the stopper 181 is returned to its original position by rotating counterclockwise by the restoring force of the spring 182 .

The operation switch 182 is provided for the user to operate when the position of the stopper 181 is to be moved, and in this embodiment, the operation switch 182 and the stopper 181 are integrally formed. Therefore, the user operates the operation switch 182 to determine the position of the stopper 181 so that when the interval between the first holding member 110 and the second holding member 120 is widened, the first opening distance D1 is opened. Or it can be adjusted to be spread apart by the second gap (D2). Here, the first gap D and the second gap D2 are defined as the gap between both gripping ends 111 and 121 .

2 for reference, in this embodiment, a separate restraining member 4 is provided, and the first restraining protrusion R1 provided on the lower first guide rod 112b on the restraining member 4 and the upper side A first restraint groove 4a and a second restraint groove 4b into which the second restraint protrusion R2 provided in the second guide rod 122a is inserted are formed. And the first restraining groove (4a) is opened in the right direction and closed in the left direction is formed to have the first restraining jaw (J1) in the closed portion, the second restraining groove (4b) in the left direction Open and closed in the right direction is formed to have a second restraining jaw (J2) in the closed portion. So, when the gap between the first gripping member 110 and the second gripping member 120 is widened, the second gaping distance D2, which is the maximum distance between the two gripping members 110, is the first restraining jaw J1 and the second It is determined by the restraint jaw (J2). That is, the first restraining jaw (J1) and the second restraining jaw (J2) limit the movement of the first restraining projection (R1) and the second restraining projection (R2), ultimately the first holding member 110 and the second It is limited that the holding member 120 is spread wider than the second gap D2. However, unlike this embodiment, since a number of mechanical designs for limiting the maximum gap between the first gripping member 110 and the second gripping member 120 may be possible, the constraining member 4 is a configuration of the present invention. It does not have to be provided separately. That is, it suffices to be mechanically implemented so that the maximum distance between the gripping members 110 and 120 becomes the second gaping distance D2.

Subsequently, the use and operation of the cradle 100 of FIG. 1 will be described.

As shown in (a) and (b) of FIG. 14 , the user selects a mobile phone MP that can be selectively changed into a first width W1 and a second width W2 wider than the first width W1. Can be used. In this case, a case in which the user mounts the cradle 100 in the state of the first width W1 will be described first.

The user manipulates the operation switch 180 to set both gripping members 110 and 120 to be opened at the first opening interval W1, and then operates the opening switch (not shown) to operate both gripping members 110 and 120 ) to be widened by the first opening distance W1. Here, the open switch may be provided separately, but may be provided in a form to automatically operate by sensing the manipulation of the manipulation switch 180 .

When the distance between the both gripping members 110 and 120 is widened by the first opening distance D1, the load amount of the motor M increases, so the control means 173 stops the operation of the motor M. Accordingly, the gap between the both gripping members 110 and 120 becomes the first gaping distance D1. After that, the user puts the bottom end of the mobile phone MP to be supported by the support member 160 .

In addition, the user instructs the gap between the gripping members 110 and 120 to be narrowed by manipulating the gripping switch (not shown). Accordingly, the control means 173 reversely rotates the motor M to narrow the gap between the both gripping members 110 and 120 . So, as the distance between the both gripping members 110 and 120 is narrowed, the gripping ends 111 and 121 of the both gripping members 110 and 120 come into contact with the left and right ends of the mobile phone MP, respectively, when the motor (M) Control means 173 stops the motor (M) as the load amount of the increases. In this way, the mobile phone MP can be stably mounted on the cradle 100 . Here, the grip switch may be provided to be operated separately, but when the user puts the mobile phone MP on the support member 160, it is automatically recognized by the recognition sensor and the gap between the grip members 110 and 120 is automatically narrowed. It may be considered desirable to allow it to be controlled.

On the other hand, when the user wants to hold the mobile phone MP in the second width W2 state, the user operates the operation switch 180 so that both gripping members 110 and 120 move to the second opening distance D2. make it happen Accordingly, both gripping members 110 and 120 are widened as much as possible so that both gripping members 110 and 120 have the second gap D2. Therefore, when both gripping members 110 and 120 are opened by the second gap D2, the user puts the mobile phone MP of the second width D2 on the support member 160. Then, as the distance between the two gripping members 110 and 120 is narrowed, both the gripping members 110 and 120 grip the left and right ends of the mobile phone MP.

Looking at the above operation state, the first width W1 in the present embodiment. The length relation between the second width W2, the first gap D1, and the second gap D2 is the second gap D2 > the second width W2 > the first gap D1 > the second gap D2. It can be seen that the width W1 is 1, which minimizes the gap between the gripping members 110 and 120 accordingly even when gripping the mobile phone MP of the first width W1, thereby increasing the speed of the gripping operation. it can be seen that
