Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to vehicle rear mirrors, and particularly to a rear mirror of a vehicle having a display, which is controlled by a dynamic unit. 
       BACKGROUND OF THE INVENTION 
       [0002]    With the advance of technology and the trend that the display is thinner and thinner, the rear mirrors of a vehicle are installed with display unit (such as thin liquid crystal display). The display can provide the function of satellite navigation, data transformation, A/V multimedia playing, and other application, moreover, the function of image capturing in back of a car is also provided. In the prior art, the combination of display and rear mirror are combined by folding the display or rotating the display to be at the backside of the rear mirror. In use, the display is unfolded or rotated out to be viewed. In one improvement, the rear mirror is installed with a retracting unit which is fixed with a display so that the display can be hidden within the rear mirror of the vehicle. In use, the retracting device will retract the display. 
         [0003]    In above mentioned structure, the folding and rotating operation is performed manually, or the display is retracted by the retracting device. However the whole structure is not steadily and the sliding guiding device is not idea so that the positioning of the whole structure is not smooth. Furthermore, the vibration of the vehicle will affect the viewing quality and the lifetime of the structure. Thus in U.S. Pat. No. 7,175,281, a track and a rack are used to guide the structure. Furthermore, teethed strip and gear are engaged to provide damping effect to improve the steadiness and smoothness in sliding. Furthermore, tenons and buckles are used to lock the structure. Elastic force of a compressible spring cause that in operation, it is only ejected outwards slightly. The tenons and buckles can be released. Furthermore, the display is pushed downwards by the elastic force so as to improve the defects of manual operation. 
         [0004]    However in the prior art, the structure of the tenons and buckles are complicated and the cost in manufacturing and assembly is high. The expansion of the display must be performed manually. It is not a humanized operation. Thus a novel power saving and simple operation design is necessary. 
       SUMMARY OF THE INVENTION 
       [0005]    Accordingly, the object of the present invention is to provide a rear mirror of a vehicle having a display which has a simple structure and assembly. A sliding and positioning unit between the body and seat is simpler so as to reduce the cost in assembly. Further, the dynamic unit is operated by a remote controller or a touch switch instead of manual operation. Thus the present invention provides the function of easy operation and manpower saving. 
         [0006]    To achieve above object, the present invention provides a rear mirror of a vehicle having a display, comprising:

     DETAILED DESCRIPTION OF THE INVENTION 
       [0027]    In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. 
         [0028]    However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims. 
         [0029]    Referring to  FIG. 1 , the rear mirror of a vehicle with a display of the present invention is illustrated, which includes the following elements. 
         [0030]    A seat  10  serves for installing an original rear mirror (not shown) at a front lateral side and aside a front wind glass of a vehicle. The seat  10  can be used to replace the original rear mirror of a vehicle. A left side of a front wall  11  of the seat  10  is installed with a vertical guide rod  12 . A right side of the front wall  11  thereof is formed with a rack  13 . One side of the seat  10  has an embedding groove  14  for installing a dynamic unit  30 . 
         [0031]    Referring to  FIG. 2 , a body  20  has a display unit  21  installed at an inner side thereof. The display unit  21  can be viewed from a front side thereof. A left wall  22  of the body  20  is protruded with a sliding block  23 . A through hole  231  penetrates through the sliding block  23  for receiving the guide rod  12  of the seat  10  so that the sliding block  23  can slide along the guide rod  12  longitudinally and limitedly. Besides, a rear wall  24  of the body  20  has a track  25  at a position with respect to the rack  13  of the seat  10 . The track  25  may receive the rack  13  and thus the rack  13  is slideable along the track  25  so as to form as a sliding guiding assembly. A rear wall  24  of the body  20  has a teeth strip  27 . 
         [0032]    Preferably, the dynamic unit  30  is a small motor and is installed at one side of the seat  10 . The dynamic unit  30  is powered by a wire  31 . An output end of the dynamic unit  30  is connected to a gear  32 . The dynamic unit  30  can be embedded into the embedding groove  14  of the seat  10 . The gear  32  is engaged to the teethed strip  27  of the body  20  and is pressed by a press plate  33  to be positioned. 
         [0033]    A mirror body  40  is installed at a front side of the seat  10  and has a mirror surface  41 . A space is formed between the mirror body  40  and the seat  10 . Besides, when the body  20  is pushed by the dynamic unit  30  to slide downwards, it exactly protrudes from a lower side of the mirror body  40 . Therefore, the user can view of the display unit  21  of the body  20 . 
         [0034]    It should by noted that as shown in  FIGS. 1 and 3 , the dynamic unit  30  on the seat  10  of the present invention includes many different operation ways. A first one is to operate it remotely through wireless control. It may be an infrared remote control. In this embodiment, a lower side of the body  20  is installed with a wireless receiver  51  and a wireless remote controller matched to the wireless receiver  51  (not shown). By operating the wireless remote controller, the wireless receiver  51  will receive infrared signals. Then the dynamic unit  30  is controlled to switch and operate so as to have the function of pushing the body  20  to slide and displace. The second way is a touch control way. In this embodiment, a lower side of the body  20  is installed with a touch switch  52 . In operation, it is only necessary to touch the touch switch  52 , the dynamic unit  30  can be controlled directly. The third way is a far end wired control. In this embodiment, a mainframe (not shown) with a touch switch or wireless remote control function is included. The mainframe is installed at a predetermined position within a vehicle. The mainframe is connected to the dynamic unit  30  by wires. Therefore, the touch switch  52  or wireless remote controller in the mainframe can be used to control the actuation of the dynamic unit  30 . The above mentioned three ways may be used to control the dynamic unit  30  easily. 
         [0035]    Besides, the present invention further provides other extra functions, and particularly to the mirror body  40 . A front upper side of the mirror body  40  may be added with a digital camera lens  53  for capturing images real time no matter the vehicle moves or is motionless. The images from the digital camera lens  53  can be transferred by satellites so as to have the function of burglar proof. 
         [0036]    Referring to  FIGS. 3 and 4 , in the rear mirror with a display according to the present invention, the seat  10  can be installed on a rear mirror of a vehicle. Normally, as it is not used, the body  20  having the dynamic unit  30  can be hidden between the mirror body  40  and the seat  10 . Thus it has an outlook approximately identical to the original rear mirror of the vehicle. Thus, the user can view the mirror surface  41  of the mirror body  40  directly to know the rear view of the vehicle. When the user desires to view the display unit  21 , the user can actuate the dynamic unit  30  by above mentioned wireless remote controller, touch switch  52  or the far end wire controller. The gear  32  of the dynamic unit  30  will rotate to drive the teeth strip  27  to push the body  20  to slide out with respect to the seat  10  so as to protrude out from the lower side of the mirror body  40  (referring to  FIGS. 5 and 6 ) so that the user can view the image data from the display unit  21 . Besides, when the user desires to hid the body  20  in the interior of the seat  10 , the user only needs to press the wireless remote controller, touch switch  52  or the far end wire controller to actuate the dynamic unit  30  to revert so as to drive the body  20  to hid into the body  20  at the rear side of the mirror body  40 . Of course, no matter the body  20  protrudes downwards or stored upwards, in the sliding process, the sliding guiding assembly between the body  20  and the seat  10  is helpful to precisely limit the sliding effect. 
         [0037]    Moreover, one side of the seat  10  can be installed with a detection element  60  and a speed detector  70 . The detection element  60  is a sensor photoelectric switch. The detection element  60  has two sensors (formed as a set) which are installed at predetermined positions at the uppermost traveling path and at the lowermost traveling path so as to detect the displacement of the body  20  and send out signals. Then the dynamic unit  30  is further controlled through the wires so as to stop the operation. By above mentioned ways, the control can be performed easily and automatically and the safety of the dynamic unit  30  is protected. The speed detector  70  has the effect of providing information to user for speed limitation so as to achieve the object of safety driving. 
         [0038]    The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
