Description

Technical Field

[0001] The present application relates to the technical field of mobile phone holders, and in particular to a mobile phone holder. Background Art

[0002] A mobile phone holder is a device that can use the mobile phone for navigation after it is fixed. However, compared with car navigation, mobile navigation is more accurate and road condition information is updated faster, which is conducive to improving driving safety.

[0003] Technical issues

[0004] When people go out by car, they need to fix their mobile phones on the mobile phone holder. The existing mobile phone holders are divided into magnetic, clip and gravity types.

When using the clip mobile phone holder, the clamping force is small, and when encountering a bumpy journey, the stability of the mobile phone clamped on the mobile phone holder is affected, and it is easy to cause looseness or slipping after multiple vibrations. Although the gravity type holder has a bottom support to prevent the mobile phone from slipping, it is large in size, which is not conducive to achieving the thinness of the mobile phone holder.

[0028] Best Mode for Carrying Out the Invention

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present invention is described in detail.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the present application provides a mobile phone holder 100, including a shell 110, a first clamping arm 120 and a second clamping arm 130 slidingly connected to the shell 110, and a swivel base 140 rotatably connected to the shell 110, the first clamping arm 120 and the second clamping arm 130 respectively extend from opposite sides of the shell 110, the swivel base 140 includes a rotating body 142, and a first extension arm 144 and a second extension arm 146 connected to the rotating body 142, the first extension arm 144 is connected to the first clamping arm 120 through a first connecting rod 150, and the second extension arm 146 is connected to the second clamping arm 130 through a second connecting rod 160, and a reset elastic member 180 is connected between the end of the first extension arm 144 and the shell 110, and / or between the end of the second extension arm 146 and the shell 110, so that the first clamping arm 120 and the second clamping arm 130 are moved closer to each other under elastic force.

[0031] Specifically, the first clamping arm 120 and the second clamping arm 130 extend from opposite sides of the housing 110, so that a space for clamping the mobile phone is formed between the first clamping arm 120 and the second clamping arm 130. In the initial state, the first clamping arm 120 and the second clamping arm 130 are elastically moved close to each other under the influence of the reset elastic member 180. The reset elastic member 180 can be a tension spring. When it is necessary to clamp the mobile phone, the first clamping arm 120 or the second clamping arm 130 is first pulled outward to separate the first clamping arm 120 and the second clamping arm 130. During the process, the first clamping arm 120 and the second clamping arm 130 are linked by the rotating seat 140, so that the first clamping arm 120 and the second clamping arm 130 move synchronously. After the mobile phone is placed between the first clamping arm 120 and the second clamping arm 130, the first clamping arm 120 and the second clamping arm 130 can be driven by the reset elastic member 180 to move close to each other to clamp the mobile phone.

[0032] Among them, by setting the swivel seat 140 to the structural form of the first extension arm 144 and the second extension arm 146 connected to the rotating body 142, the ends of the first extension arm 144 and the second extension arm 146 can have a larger torque. When the reset elastic member 180 is connected between the end of the first extension arm 144 and the shell 110, and / or the reset elastic member 180 is connected between the end of the second extension arm 146 and the shell 110, the reset elastic member 180 can provide a larger torque for the rotation of the swivel seat 140 to ensure the clamping force of the first clamping arm 120 and the second clamping arm 130 when clamping the mobile phone, which is beneficial to prevent the mobile phone from loosening and falling due to excessively small clamping force.

[0033] It can be understood that when the first extension arm 144 and the second extension arm 146 rotate, in order to convert the rotation of the swivel seat 140 into the linear motion of the first clamping arm 120 and the second clamping arm 130, it is necessary to connect the first connecting rod 150 between the first extension arm 144 and the first clamping arm 120, and connect the second connecting rod 160 between the second extension arm 146 and the second clamping arm 130. Specifically, one end of the first connecting rod 150 is rotationally connected to the first extension arm 144, the other end of the first connecting rod 150 is rotationally connected to the first clamping arm 120, one end of the second connecting rod 160 is rotationally connected to the second extension arm 146, and the other end of the second connecting rod 160 is rotationally connected to the second clamping arm 130, so as to realize the required linkage transmission.

[0034] The mobile phone holder 100 provided in the embodiment of the present application, through the swivel base 140 rotatably connected to the shell 110, when the first clamping arm 120 or the second clamping arm 130 is pulled by external force, the swivel base 140 drives the first extension arm 144 and the second extension arm 146 to rotate synchronously through the rotating body 142, and the end of the first extension arm 144 is connected to the first clamping arm 120 through the first connecting rod 150, and the end of the second extension arm 146 is connected to the second clamping arm 130 through the second connecting rod 160, which can drive the first clamping arm 120 and the second clamping arm 130 to move synchronously, so as to achieve the synchronous separation of the first clamping arm 120 and the second clamping arm 130. At the same time, by connecting the resetting elastic member 180 between the end of the first extension arm 144 and the housing 110, and / or between the end of the second extension arm 146 and the housing 110, the resetting elastic member 180 can provide a greater rotational torque for the rotation of the swivel 140. In this way, under the elastic force of the resetting elastic member 180, when the mobile phone is clamped by the first clamping arm 120 and the second clamping arm 130, there is a greater clamping force, which is conducive to improving the stability during clamping. In addition, compared with conventional gravity brackets, the mobile phone bracket 100 eliminates the bottom bracket structure, thereby reducing the thickness space required for the connection between the bottom bracket and the swivel 140, which is conducive to achieving overall lightness and thinness.

[0035] like Figure 3 As shown, the first clamping arm 120 includes a first sliding portion 122 and a first clamping portion 124 connected to each other, and the first sliding portion 122 is slidably connected to the shell 110; the second clamping arm 130 includes a second sliding portion 132 and a second clamping portion 134 connected to each other, and the second sliding portion 132 is slidably connected to the shell 110.

[0036] Specifically, the first sliding portion 122 and the second sliding portion 132 fit in the length direction of the shell 110 to facilitate sliding cooperation with the shell 110. The opposite sides of the first clamping portion 124 and the second clamping portion 134 can achieve the clamping effect on the mobile phone. There is a preset angle between the first sliding portion 122 and the first clamping portion 124. Similarly, there is a preset angle between the second sliding portion 132 and the second clamping portion 134 to ensure that the first clamping portion 124 and the second clamping portion 134 can protrude from the shell 110 to achieve clamping of the mobile phone.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the shell 110 includes a front shell 111 and a rear shell 112 that are arranged opposite to each other, a first sliding groove 1222 is arranged on the first sliding portion 122, a second sliding groove 1322 is arranged on the second sliding portion 132, and a first protrusion 116 corresponding to the first sliding groove 1222 and a second protrusion 117 corresponding to the second sliding groove 1322 are arranged on the front shell 111 or the rear shell 112.

[0038] Specifically, when the first sliding part 122 and the second sliding part 132 slide relative to the shell 110, in order to ensure the straightness of the first sliding part 122 and the second sliding part 132 when sliding, a first sliding groove 1222 can be provided on the first sliding part 122, and a second sliding groove 1322 can be provided on the second sliding part 132, and a first protrusion 116 corresponding to the first sliding groove 1222 and a second protrusion 117 corresponding to the second sliding groove 1322 are provided on the front shell 111 or the rear shell 112. When they cooperate with each other, the first protrusion 116 is inserted into the first sliding groove 1222, and the second protrusion 117 is inserted into the second sliding groove 1322, so as to achieve the function of limiting the first sliding part 122 and the second sliding part 132, thereby ensuring the stability of the sliding connection.

[0039] In an optional embodiment of the present application, a plurality of first slide grooves 1222 are arranged in parallel, and the first protrusions 116 are arranged in one-to-one correspondence with the first slide grooves 1222; a plurality of second slide grooves 1322 are arranged in parallel, and the second protrusions 117 are arranged in one-to-one correspondence with the second slide grooves 1322.

[0040] Specifically, by arranging the first protrusions 116 and the first slide grooves 1222 into a plurality of groups, and arranging the first protrusions 116 and the first slide grooves 1222 in a one-to-one correspondence, it is helpful to ensure the balance of force when the first sliding part 122 slides, so as to ensure the smoothness of sliding. Similarly, by arranging the second protrusions 117 and the second slide grooves 1322 into a plurality of groups, and arranging the second protrusions 117 and the second slide grooves 1322 in a one-to-one correspondence, it is helpful to ensure the balance of force when the second sliding part 132 slides, so as to ensure the smoothness of sliding.

[0041] like Figure 2 As shown, a locking member 190 is further provided on the housing 110 , and the locking member 190 can be locked with the first sliding portion 122 or the second sliding portion 132 .

[0042] Specifically, the first sliding part 122 or the second sliding part 132 is clamped by the locking piece 190. Since the first sliding part 122 forms a linkage relationship with the second sliding part 132 through the swivel seat 140, as long as the first sliding part 122 or the second sliding part 132 is clamped, the first clamping arm 120 and the second clamping arm 130 can be prevented from being moved away by external force, thereby ensuring the stability of the mobile phone clamping. When encountering bumpy roads during driving, the risk of the mobile phone holder 100 slipping due to changes in clamping force caused by vibration can be reduced.

[0043] like Figure 4 and Figure 5As shown, the locking member 190 includes a first pressing portion 191, a rotating portion 192 and a second pressing portion 193 which are connected in sequence. The rotating portion 192 is rotatably connected to the housing 110. The second pressing portion 193 is provided with a first latching protrusion 1932 and a second latching protrusion 1934, and a gap 194 is provided between the first latching protrusion 1932 and the second latching protrusion 1934. The first sliding portion 122 or the second sliding portion 132 is provided with a latching tooth 1324 corresponding to the first latching protrusion 1932. The housing 110 is provided with a first latching groove 118 and a second latching groove 119 corresponding to the second latching protrusion 1934, and the first latching groove 118 and the second latching groove 119 are spaced apart. When the second latching protrusion 1934 corresponds to the first latching groove 118, the first latching protrusion 1932 is engaged with the latching tooth 1324. When the second latching protrusion 1934 corresponds to the second latching groove 119, the first latching protrusion 1932 is released from the latching tooth 1324.

[0044] Specifically, by configuring the locking member 190 to include a first pressing portion 191, a rotating portion 192, and a second pressing portion 193 that are sequentially connected, when the second locking protrusion 1934 needs to correspond to the first locking groove 118, the second pressing portion 193 is pressed to rotate the locking member 190 relative to the housing 110 until the second locking protrusion 1934 is inserted into the first locking groove 118, so that the locking member 190 locks the first clamping arm 120 and the second clamping arm 130. When the second locking protrusion 1934 needs to correspond to the second locking groove 119, the first pressing portion 191 is pressed to rotate the locking member 190 in the opposite direction relative to the housing 110 until the second locking protrusion 1934 is inserted into the second locking groove 119, so that the locking member 190 releases the locking of the first clamping arm 120 and the second clamping arm 130. It is understandable that in order to ensure the smooth switching of the second latching protrusion 1934 at the first latching slot 118 and the second latching slot 119, it is necessary to set an arc-shaped guide surface between the first latching slot 118 and the second latching slot 119 to ensure the smoothness of the locking member 190 when switching positions and avoid the occurrence of a jamming phenomenon. In addition, a gap 194 is set between the first latching protrusion 1932 and the second latching protrusion 1934. When the second latching protrusion 1934 switches positions, the second latching protrusion 1934 can generate elastic deformation, thereby ensuring the smooth switching of the position of the second latching protrusion 1934 and stably maintaining it at the switched position.

[0045] like Figure 3 As shown, the first clamping portion 124 is provided with a first limiting groove 1242 with two ends open, and the second clamping portion 134 is provided with a second limiting groove 1342 with two ends open. The first limiting groove 1242 and the second limiting groove 1342 are used to clamp the diagonals of the mobile phone.

[0046] Specifically, when clamping a mobile phone, the two sides of the mobile phone can be clamped by the opposite sides of the first clamping part 124 and the second clamping part 134, or the diagonal sides of the mobile phone can be clamped into the first limiting groove 1242 and the second limiting groove 1342 as needed, so as to clamp the mobile phone. Among them, the method of clamping and limiting the mobile phone by the first limiting groove 1242 and the second limiting groove 1342 can further limit the mobile phone by the first limiting groove 1242 and the second limiting groove 1342 to prevent the mobile phone from moving relative to the first clamping part 124 and the second clamping part 134, and has a better clamping effect to ensure the stability of the current clamping state, thereby improving the safety during use. It can be understood that the angle between the two sides of the first limiting groove 1242 and the second limiting groove 1342 in the width direction is a right angle to adapt to the four corners of the mobile phone.

[0047] In an optional embodiment of the present application, the opening area of ​​the first clamping portion 124 and the second clamping portion 134 on the opposite side is larger than the opening area of ​​the opposite side.

[0048] Specifically, by making the area of ​​the opening on the opposite side of the first clamping portion 124 and the second clamping portion 134 larger than the area of ​​the opening on the opposite side, the first clamping portion 124 and the second clamping portion 134 have a larger contact area when clamping the opposite sides of the mobile phone, which is beneficial to ensure the stability of clamping. At the same time, it can also ensure that when clamping the diagonal corners of the mobile phone, the diagonal corners of the mobile phone can be smoothly inserted into the first clamping portion 124 and the second clamping portion 134.

[0049] like Figure 3 and Figure 4 As shown, a first protective pad 1244 is disposed in the first limiting groove 1242 , and the first protective pad 1244 wraps the edge of the inner opening of the first limiting groove 1242 ; a second protective pad 1344 is disposed in the second limiting groove 1342 , and the second protective pad 1344 wraps the edge of the inner opening of the second limiting groove 1342 .

[0050] Specifically, by setting the first protection pad 1244 in the first limiting groove 1242 and the second protection pad 1344 in the second limiting groove 1342, when the mobile phone is clamped by the first clamping part 124 and the second clamping part 134, the first protection pad 1244 wraps the inner opening edge of the first limiting groove 1242, and the second protection pad 1344 wraps the inner opening edge of the second limiting groove 1342, so that the first protection pad 1244 and the second protection pad 1344 can directly contact the mobile phone to avoid rigid abutment. When clamping the diagonal of the mobile phone, the first protection pad 1244 and the second protection pad 1344 can also protect the mobile phone.

[0051] like Figure 4As shown, at least one first guide ridge 113 corresponding to the first sliding portion 122 and at least one second guide ridge 114 corresponding to the second sliding portion 132 are disposed in the housing 110 .

[0052] For example, when the locking member 190 corresponds to the second sliding portion 132, the first guide ridges 113 can be arranged in parallel to form two. By setting the first guide ridges 113 in parallel in the housing 110, a space for the first sliding portion 122 to slide can be formed between the two first guide ridges 113, so as to guide the sliding of the first sliding portion 122. At the same time, the first guide ridges 113 can also serve as reinforcing ribs to strengthen the strength of the housing 110. It can be understood that when the locking member 190 corresponds to the second sliding portion 132, a latching tooth 1324 corresponding to the locking member 190 is arranged on one side of the second sliding portion 132. In order to avoid interference with the normal locking of the locking member 190, a second guide ridge 114 can be arranged in the housing 110 to guide the sliding of the second sliding portion 132. At the same time, the second guide ridge 114 can also serve as reinforcing ribs to strengthen the strength of the housing 110. When the locking member 190 corresponds to the first sliding portion 122 , the configuration of the first guide ridge 113 and the second guide ridge 114 are opposite, which will not be described in detail.

[0053] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the protection scope of the claims attached to the present invention.
