Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a retaining device for a vehicle reversing sensor, and more particularly to a retaining device that can be directly mounted on the vehicle without any destructive installment.  
         [0003]     2. Description of Related Art  
         [0004]     As well known in the art, a vehicle reversing system is composed of two main parts, a radar sensor mounted on the rear portion of the vehicle and a controller connected to the radar sensor. Since the controller is usually fitted in the interior of the car and not exposed, only the ordered lines layout for the controller is required.  
         [0005]     On the other hand, the installation operation of the radar sensor is implemented by placing the radar sensor into a drilled hole in the rear bumper. Such a drilling operation may cause damage to the appearance of the vehicle if the workman lacks sufficient skill.  
         [0006]     Therefore, there is a desire to have a superior solution to mount the radar sensor on the vehicle to obviate the aforementioned drawback.  
       SUMMARY OF THE INVENTION  
       [0007]     The main objective of the present invention is to provide a retaining device that allows the radar sensor to be installed in the vehicle without any destructive installation operation to prevent any possible damage to the vehicle appearance.  
         [0008]     Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0016]     With reference to  FIG. 1 , a first embodiment of a retaining device for a vehicle reversing radar sensor is composed of a housing ( 10 ) and a fastener ( 20 ). The housing ( 10 ) having a chamber defined therein to receive a radar sensor (not shown), has a rear surface on which two substantially semicircular platforms ( 13 ) are oppositely formed to define a narrow path ( 11 ) between the two platforms ( 13 ). Two slots ( 110 ), parallel to the narrow path ( 11 ), are defined into the opposite sidewalls of the two platforms ( 13 ). Two blocks ( 12 ) that protrude from the rear surface of the housing ( 10 ) are formed near one end of the narrow path ( 11 ). Each block ( 12 ) is formed to have a slope.  
         [0017]     The fastener ( 20 ) includes a first engagement member and a second engagement member. The first engagement member is applied to achieve a connection with the narrow path ( 11 ) thereby assembling the fastener ( 20 ) to the housing ( 10 ). The second engagement member is used for clamping the fastener ( 20 ) to an edge of a rear cover of the vehicle (as shown in  FIG. 4 ).  
         [0018]     As shown in  FIGS. 2 and 3 , the fastener ( 20 ) has a clamping base ( 23 ) with a U-shaped cross-section. The clamping base ( 23 ) is formed by a bottom plate with two opposite edges from which a front plate ( 22 ) and a rear plate ( 21 ) integrally and perpendicularly extend. The front plate ( 22 ) is shorter than the rear plate ( 21 ) in the length but is wider than the rear plate ( 21 ) in the width. Furthermore, the distance between the front plate ( 22 ) and the rear plate ( 21 ) depends on the thickness of the rear cover of the vehicle.  
         [0019]     Two through holes ( 210 ) are defined near one end of the rear plate ( 21 ) to correspond to the two blocks ( 12 ) of the housing ( 10 ). When the rear plate ( 21 ) slides along the path ( 11 ), two opposite edges of the rear plate ( 21 ) are tightly abutted against the sidewalls of the two slots ( 110 ). Further, the two blocks ( 12 ) are securely retained in the two through holes ( 210 ).  
         [0020]     An auxiliary element is further attached to a first surface of the rear plate ( 21 ). The auxiliary element could be an adhesive strip ( 24 ) to enhance the connection between the fastener ( 20 ) and the surface of the rear cover. Another alternate embodiment of the auxiliary element is a magnet by which the fastener ( 20 ) is attached to the rear cover by magnetic force.  
         [0021]     With reference to FIGS.  4  to  7 , to install the retaining device in company with the radar sensor to the vehicle ( 30 ), the rear cover ( 31 ) is firstly raised so that the lower edge of the rear cover ( 31 ) can be securely clamped by the base ( 23 ) between the front plate ( 22 ) and the rear plate ( 21 ). Because the fastener ( 20 ) is made of thin metal plate, the front plate ( 22 ) functions as a resilient clamp to tightly abut against the surface of rear cover. In  FIG. 6 , the front plate ( 22 ) is further defined with a hole, whereby a screw ( 25 ) can insert through the hole to press against the surface rear cover ( 31 ) to enhance the engagement force.  
         [0022]     Based on the foregoing discussion, the first engagement member of the fastener ( 20 ) includes the rear plate ( 21 ) together with the through holes ( 210 ) to perform the connection to the housing ( 10 ). In another aspect, the second engagement member includes the front plate ( 22 ) and the U-shaped base ( 23 ) for attaching to the vehicle ( 30 ).  
         [0023]     With reference to  FIG. 7 , when the rear cover ( 31 ) is pushed downwardly and closed, the open/close action of the rear cover ( 31 ) is not obstructed even when the retaining device is attached. The radar sensor secured by the retaining device is exposed to aim from the rear area of the vehicle ( 30 ) to transmit/receive detecting signals.  
         [0024]     It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
