Title: Support

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a support and in particular, to a support used for mobile equipment. 
     2. Description of the Related Art 
     The size of the prior supports for mobile equipment is substantially fixed, and adjustment on the size is unavailable. There are various sizes of current mobile equipment such as the mobile phone; although most mobile equipment can be clamped, but the prior supports may clip the button set on the side of the mobile phone when clamping due to the difference in size, and cause the misoperation. Moreover, adjustment on the size of some prior supports with wireless charging function is unavailable, so the mobile phone can not be aligned with the transmitting coil, which significantly affects the charging efficiency and is inconvenient for the user. 
     The prior supports for mobile equipment are often required to be clamped and fixed manually, which is very inconvenient on operation. Although there are also few supports that designed by automatic clamping, for example, by detecting the rotation state of mobile equipment, the electric drive is controlled to achieve automatic clamping, but they have the disadvantages of complex structures, high production costs, and high power consumption. There also exist some supports that use the linkage mechanism to achieve automatic clamping, but the linkage stability and the clamping effect of the prior linkage mechanism are not good enough, and the resetting effect is poor.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     As shown in  FIG. 1 , the exploded view illustrates the telescopic rod of the invention. The telescopic rod  100  comprises a fixing rod  110  and a movable rod  120  sheathed on the fixing rod  110  and adjusted up and down relative to the fixing rod  110 , wherein a pull trough  130  is arranged on the fixing rod  110 , and a plurality of bulges  140  are arranged at the pull trough  130 . The movable rod  120  comprises: a movable rod front shell  121  and a movable rod back shell  122 , wherein an elastic clamping piece  150  is arranged on the movable rod front shell  121  or the movable rod back shell  122 ;  FIG. 1  shows the arrangement of the elastic clamping piece  150  at the movable rod front shell  121 , a short shaft is arranged inside the elastic clamping piece  150 , the elastic clamping piece  150  is arranged and can move in the pull trough  130 , and a buckle connection capable of adjusting the movable rod  120  up and down is formed by the elastic clamping piece  150  and the bulges  140  at the pull trough. 
     Further, as shown in  FIG. 2 , an operation part  123  for pressing the elastic clamping piece  150  is arranged on the external surface of the movable rod front shell  121 . When the elastic clamping piece  150  is pressed by the operation part  123 , the elastic clamping piece  150  can slide in the pull trough  130  without hindrance; when the elastic clamping piece  150  is loosened, the elastic clamping piece  150  contacts and engages with the bulges  140 , thereby the movable rod  120  is fixed, and adjustment on the size of the telescopic rod is available. 
     As shown in  FIG. 2  to  FIG. 5 , wherein  FIG. 2  is the stereoscopic view illustrating the structure of the support according to an embodiment of the invention;  FIG. 3  is the stereoscopic view illustrating the structure of the support of the invention after removing the support front shell;  FIG. 4  is the exploded schematic view of the invention;  FIG. 5  is the exploded schematic view illustrating the partial structure of the invention;  FIG. 6  is the schematic view of the invention illustrating the state that the mobile phone is being charged. 
     The support further comprises a support front shell  20 ; a support back shell  30  forming an accommodating space with the support front shell  20 ; and a clamping mechanism  10  arranged between the support front shell  20  and the support back shell  30 ; wherein the clamping mechanism comprises a telescopic rod  100 , a left clamping arm  310  and a right clamping arm  320  arranged on both sides of the support, configured to clamp objects from left and right respectively; the left clamping arm  310  and the right clamping arm  320  are hinged with the support front shell  20  or the support back shell  30  respectively, a linkage mechanism for driving the left clamping arm  310  and the right clamping arm  320  to automatically clamp is formed when the telescopic rod does a downward movement, and mobile equipment such as the mobile phone  200  are clamped; the telescopic rod, the left clamping arm  310  and the right clamping arm  320  form a “Y” shape. 
     In particular, when the left clamping arm  310  is hinged with the support front shell  20 , the right clamping arm  320  can be hinged with the support front shell  20  or the support back shell  30 ; when the left clamping arm  310  is hinged with the support back shell  30 , the right clamping arm  320  can also be hinged with the support front shell  20  or the support back shell  30 . 
     It can be understood that the telescopic rod may also be replaced by the lower pull rod, replacing the telescopic rod with the lower pull rod; the difference between the telescopic rod and the lower pull rod is that the lower pull rod is the rod with fixed length, while the telescopic rod is the rod that can be telescoped and changed in length. 
     Further, the support of the invention uses the fixing rod  110  of the telescopic rod or uses the movement of the lower pull rod to drive the left clamping arm  310  and the right clamping arm  320  to move. 
     In particular, a guide post  330  is arranged on the fixing rod  110  or the lower pull rod, and arranged in a guide chute  340  on the left clamping arm  310  and the right clamping arm  320  respectively, that is, the guide post  330  is matched with the guide chute  340  to form a linkage mechanism; when the fixing rod  110  or the lower pull rod move downward, the guide post  330  moves in the guide chute  340 , and drives the left clamping arm  310  and the right clamping arm  320  to rotate and automatically clamp. It can be seen that the structure of the linkage mechanism of the invention is simple, the linkage is more stable, and mobile equipment such as the mobile phone  200  can be clamped better. 
     In practice, when mobile equipment such as the mobile phone  200  is clamped by the support, the movable rod  120  is adjusted according to the size of the mobile phone  200  to extend the overall length of the telescopic rod, and the button on the side of the mobile phone  200  can be effectively prevented from being clamped, which is convenient for the user. 
     Furthermore, as shown in  FIG. 4 , an elastic resetting component  40  is arranged in the accommodating space, configured to restore the fixing rod  110 , the left clamping arm  310  and the right clamping arm  320  to initial states thereof. The compression spring in  FIG. 4  is used as the elastic resetting component  40 ; one end of the elastic resetting component  40  is connected with the left clamping arm  310  or the right clamping arm  320 , and the other end thereof is connected with the support front shell  20  or the support back shell  30 . 
     In particular, when one end of the elastic resetting component  40  is connected with the left clamping arm  310 , the other end thereof can be connected with the support front shell  20  or the support back shell  30 ; when one end of the elastic resetting component  40  is connected with the right clamping arm,  320  the other end thereof can also be connected with the support front shell  20  or the support back shell  30 . 
     In use, when mobile equipment such as the mobile phone  200  is removed from the support, the elastic resetting component  40  restores the clamping mechanism to the initial state thereof by its own elastic performance for the next use. 
     In particular use, the user can manually pull down the fixing rod  110 , or directly use the weight of mobile equipment such as the mobile phone  200  to move the fixing rod  110  downward, and adjust the movable rod  120  through the operation part  123  to extend the overall length of the telescopic rod, and the linkage mechanism drives the left clamping arm  310  and the right clamping arm  320  to move, so as to clamp mobile equipment such as the mobile phone  200 . When there is no demand for continue use, it is only needed to remove the mobile phone  200 ; the clamping mechanism is automatically restored to the initial state according to the elastic feature of the elastic resetting component  40 . The whole process is simple to operate, and the manual clamping by the user is not required, which is convenient for the user. 
     Preferably, the elastic resetting component  40  can be any one of an extension spring, a torsion spring or other elastic components. And in order to make the structure simpler, the elastic resetting component  40  can be arranged with one or more of them. Two elastic resetting components  40  are preferably arranged in the embodiment. Of course, when the elastic resetting component  40  selects different types of elastic component, the installation and setup of the elastic resetting component  40  are different. 
     In particular, the elastic resetting component  40  may be connected with the left clamping arm  310  or the right clamping arm  320  at one end, with the other end connected with the support front shell  20  or the support back shell  30 , or the two ends are respectively arranged on the left clamping arm  310  and the right clamping arm  320 . It should be noted that this embodiment does not limit the type of the elastic resetting component  40 , other elastic components capable of achieving the above functions all fall within the scope of the invention. 
     Further, in order to maintain the vertical movement of the fixing rod  110  and increase the stability of the clamping mechanism, a limiting piece  50  for limiting the fixing rod  110  is arranged on the support front shell of the invention to avoid the left and right swing of the fixing rod while moving downward. 
     Moreover, a limiting slot  60  for controlling movement ranges of the left clamping arm  310  and the right clamping arm  320  is formed on the support front shell of the invention; the limiting slot  60  is arranged with baffles on both sides, wherein the baffle makes the movement ranges of the left clamping arm  310  and the right clamping arm  320  reasonable, and the support of the invention can be applied to most sizes of mobile equipment. 
     Of course, another slot can be further arranged in the fixing rod  110  of the invention, and the limiting piece is further arranged on the slot; a block is arranged on the support front shell  20 , and the block is formed in the slot of the lower pull rod; when the fixing rod  110  moves downward, the contact between the limiting piece of the slot and the block of the support front shell  20  may also limit movement ranges of the left clamping arm  310  and the right clamping arm  320 . 
     Further, two clamping ends  121  are arranged at the tail of the movable rod  120 , and one clamping end  121  is respectively arranged at the tails of the left clamping arm  310  and the right clamping arm  320 . The clamping end  121  is used for clamping mobile equipment such as the mobile phone  200 , and in order to prevent the mobile phone  200  from being damaged when the clamping end is in contact with mobile equipment such as the mobile phone  200 , a protective cover  350  made of a soft material such as the elastic rubber is sheathed on the clamping end in the embodiment, and the protective cover  350  made of a soft material also has the non-slip effect, so that the mobile phone  200  can be better clamped and fixed. 
     Further, a transmitting coil  70  for charging mobile equipment is arranged in the accommodating space of the invention, a winding device  80  driven with a shrapnel is arranged on the transmitting coil  70 , and a data line is wound on the winding device  80 ; the charging interface is arranged outside the support back shell  30 , so that the support of the invention has the wireless charging function. It can be understood that the charging circuit board  81  connected with the transmitting coil  70  may be arranged in the accommodating space. 
     In particular use, when mobile equipment such as the mobile phone  200  needs to be charged, the mobile phone  200  only needs to be placed on the clamping end of the movable rod  120 ; the clamping mechanism (the left clamping arm  310  and the right clamping arm  320 ) moves downward by using the weight of the mobile phone  200 , and the length of the movable rod  120  is adjusted by the operation part  123 ; the linkage mechanism drives the left clamping arm  310  and the right clamping arm  320  to clamp the mobile phone  2000 , ensuring that the mobile phone  200  is aligned with the transmitting coil  70 , so as to improve the charging efficiency of the mobile phone  200 . When the support needs to be charged, the data line can be pulled out simply by pulling the charging interface outside, when the data line needs to be withdrawn, the data line is automatically withdrawn to the winding device  80  by the spring-back function of the shrapnel. 
     The support further comprises the fixing piece  90  for installing and fixing the support, and the support can be fixed on other components through the fixing piece  90 . Preferably, the fixing piece  90  an be a clamping jaw or, the fixing piece  90  comprises a connecting piece  91  fixed on the support back shell  30  and a fixing clamp  92  rotatably connected with the connecting piece  91 , wherein the fixing clamp  92  comprises a clamping body  921  and a connecting rod  922  fixed on the clamping body  921 . For example, the support of the invention is installed on the air outlet of the automobile by the clamping jaw, and the mobile phone  200  can be placed and fixed during driving. 
     A luminous film is arranged on the external surface of the support front shell  20  of the invention, so that the support front shell  20  emits fluorescence at night to prompt the specific position of the support, which is convenient on operation to the user; the problem can be avoided that it is difficult for the user to determine the specific position of the support and thus, it takes a long time to place the mobile phone  200  due to the dark light at night, which not only brings inconvenience to the user, but also increases the risk of driving safety.
