[0001] The present invention relates to the technical field of vehicle key management, and in particular to an intelligent vehicle key management device. Background Art

[0002] With the continuous increase in the number of cars, the car rental industry has also achieved great development. The traditional car rental industry requires the renter to meet with the rental company staff face to face to obtain the car keys and the corresponding vehicle. With the continuous development of technology, smart key cabinets have replaced the functions of rental staff. The renter can obtain the key of the corresponding vehicle through the smart key cabinet. After using the car, the key can be returned to the key cabinet. The smart key cabinet monitors the usage time during the return process. However, the current smart key cabinets still have certain disadvantages. A label needs to be attached or marked on each key to facilitate the renter to identify the key label. When returning the car, the renter needs to enter the key label on the touch screen of the key cabinet so that the key cabinet system can identify the corresponding vehicle. This process invisibly increases the operating steps for the renter and easily brings a bad experience to the renter. In addition, the label on the key is easy to fall off or get dirty after long-term use, resulting in the renter being unable to recognize the label, affecting the return process.

DETAILED DESCRIPTION

[0020] In order to better understand the technical content of the present invention, a specific embodiment is provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0021] See also Figures 1 to 3The present invention provides an intelligent car return key management device, which includes a cabinet 1, a touch screen 2, a main control unit 3, a key 4, an electromagnetic lock 5, a cabinet door 6 and an identification mechanism. The cabinet 1 is provided with a plurality of storage cavities 7 on the side wall. One side of the cabinet door 6 is hinged to the storage cavity 7. The electromagnetic lock 5 is provided on the side wall of the storage cavity 7 for locking the cabinet door 6. The main control unit 3 and the touch screen 2 are provided on the side wall of the cabinet 1; the identification mechanism includes a storage slot box 8, an external plate 9, a positioning column 10, a force plate 11, a push rod 12, a reset spring 13 and a trigger button 14. The storage slot box 8 is provided on the inner wall of the cabinet door 6, and its opening is provided upward. There are several limit slots 22, which extend upward to the top surface of the storage slot box 8. The force-bearing plate 11 is slidably set in the limit slot 22, and the return spring 13 is connected to the side wall of the limit slot 22 and the side wall of the force-bearing plate 11. The push rod 12 is set on the side wall of the force-bearing plate 11 facing the limit slot 22. The trigger button 14 is set on the side wall of the limit slot 22 and is located on the side of the moving stroke of the push rod 12. The positioning column 10 is set on the external plate 9, and the external plate 9 is set on the handle body 15 of the key 4. The position and number of the positioning columns 10 on the external plates 9 of different keys 4 are different; the main control unit 3 is electrically connected to the touch screen 2, the electromagnetic lock 5 and the trigger button 14 respectively.

[0022] The present invention provides an intelligent car return key management device for intelligently managing the keys 4 used for car rental. The main body is a cabinet 1, and a plurality of storage cavities 7 are provided on the cabinet 1. The storage cavities 7 are opened and closed by cabinet doors 6. A storage slot box 8 is provided on the inner side of the cabinet door 6, and the key 4 is set in the storage slot box 8. When a car renter needs to use the car, he / she sends a car use request through the touch screen 2. The main control unit 3 can randomly open a cabinet door 6 where the key 4 is stored, and then the car renter can take the key 4 away. At the same time, the vehicle information will be displayed on the touch screen 2 to facilitate the car renter to find the corresponding vehicle for use. When the vehicle needs to be returned after use, the car renter sends a return request through the touch screen 2. The main control unit 3 randomly opens an empty cabinet door 6, and then the car renter can put the key 4 into the storage slot box 8. Finally, the cabinet door 6 is closed to complete the car return operation. The touch screen 2 will display information such as the length of time and fee of the vehicle used, so that the car renter can check and pay.

[0023] In order to reduce the number of operating steps for the renter, the present invention does not require the renter to select the vehicle and enter the key 4 number when returning the car. An external plate 9 is fixedly set on the handle 15 of the key 4, and a plurality of positioning columns 10 are set on the external plate 9. The positions and numbers of the positioning columns 10 on the external plates 9 of different key 4 handles 15 are different, which serve as the mark of the key 4. When the key 4 is stored in the storage slot box 8, the key 4 is turned upside down so that the positioning columns 10 on the external plate 9 pass through the top of the limit slot 22 and then move downward. When the key 4 moves downward, the positioning column 10 will contact the force-bearing plate 11, so that the force-bearing plate 11 is pushed. When the force-bearing plate 11 moves toward the inside of the limit groove 22, the push rod 12 set on its side wall will move toward the trigger button 14 and finally press the trigger button 14. After the trigger button 14 is pressed, an electrical signal is sent to the main control unit 3. The main control unit 3 can obtain the label of the key 4 according to the position and number of times the trigger button 14 is pressed, thereby obtaining the vehicle information corresponding to the key 4 for display on the touch screen 2.

[0024] Similarly, when the car renter needs to take out the key 4, he will directly pull out the key 4 from the storage slot box 8. During the pulling-out process, the positioning column 10 will press the trigger button 14 again through the force plate 11 and the push rod 12. The key 4 number can be obtained through the position and number of times the trigger button 14 is pressed, thereby obtaining the vehicle information for monitoring the use of the vehicle.

[0025] For the positioning posts 10 on the external plate 9 of the key 4, their arrangement position and number determine the label of the key 4, and the specific setting can be set according to the number and classification of the vehicles of the car rental company. For example, when the positioning post 10 is in the first row and the first column, it represents the label 1, when it is in the first row and the second column, it represents the label 2, and so on. When all the positioning posts 10 are set in the first row, the positioning posts 10 can be set in the second row. When setting the positioning posts 10 in the same column, it is necessary to ensure that the positioning posts 10 in the same column of the previous row always exist. For example, when the positioning post 10 needs to be set in the first column of the second row, it is necessary to ensure that the positioning post 10 is set in the first column of the first row. When the key 4 is taken out and placed in the storage slot box 8, the trigger button 14 in the same limit slot 22 will be triggered twice back and forth, which is used as the judgment of the label of the key 4. The label of the corresponding key 4 can be obtained by the position and number of times the trigger button 14 is pressed. That is to say, by making different combinations of the position and number of the positioning posts 10, a variety of key 4 labels can be obtained, such as Figure 2 The key 4 shown is provided with only one positioning column 10 , and the circular area on the external plate 9 is the location for installing the positioning column 10 .

[0026] The size of the force-bearing plate 11 can be embedded between two upper and lower positioning columns 10. If there are multiple positioning columns 10 in the same column, after the previous positioning column 10 leaves the force-bearing plate 11, the force-bearing plate 11 can be restored to its initial position under the action of the reset spring 13. After the next positioning column 10 contacts the force-bearing plate 11, the trigger button 14 can be pressed again to ensure that the trigger button 14 in the limit slot 22 can be triggered multiple times.

[0027] In addition, the order in which the trigger button 14 is pressed when the key 4 is taken out and placed into the storage slot box 8 is opposite, so two sets of identification strategies can be formulated and preset in the main control unit 3 to facilitate the identification of the key 4 label during the key 4 removal and placement process.

[0028] Preferably, when the handle 15 of the key 4 is fully inserted into the storage slot box 8 , the distance between the bottom surface of the force-bearing plate 11 and the bottom surface of the storage slot box 8 is greater than the height of any positioning column 10 from the bottom surface of the storage slot box 8 .

[0029] When the key 4 is completely stored in the storage slot box 8, the force plate 11 can rebound to its original position. At this time, all the positioning columns 10 are under the force plate 11, so that when the key 4 is taken out, the positioning columns 10 can trigger the force plate 11 again.

[0030] Preferably, the force-bearing plate 11 is an arc-shaped structure, the push rod 12 is provided on the concave surface of the force-bearing plate 11 , and one end of the return spring 13 is connected to the concave surface of the force-bearing plate 11 .

[0031] The force-bearing plate 11 is configured as an arc-shaped structure to facilitate the pushing of the positioning column 10 .

[0032] Preferably, a slider 16 is provided on the side wall of the force-bearing plate 11 , a slide groove 17 is provided on the side wall of the limiting groove 22 , the slide groove 17 is arranged perpendicular to the limiting groove 22 , and the slider 16 is located in the slide groove 17 .

[0033] The slide groove 17 is parallel to the horizontal line and is therefore perpendicular to the limit groove 22. When the force-bearing plate 11 is pushed by the positioning column 10, it will not move downward, but move in the horizontal direction, causing the slider 16 to slide in the slide groove 17 to prevent the force-bearing plate 11 from shifting.

[0034] Preferably, the identification mechanism further includes a weighing sensor 18 , which is disposed on the bottom surface of the storage box 8 , and the main control unit 3 is electrically connected to the weighing sensor 18 .

[0035] The set weighing sensor 18 is used to detect whether the key 4 is in the storage slot box 8, so that when returning the car, the cabinet door 6 with the key 4 or the empty cabinet door 6 can be selected. At the same time, when identifying the number of the key 4, the data collected by the weighing sensor 18 before and after the trigger button 14 is triggered can be used to determine whether the identification process is to use the car or return the car, so that the key 4 number can be obtained according to different identification strategies.

[0036] Preferably, a metal plate 19 is provided on the inner side of the cabinet door 6 , and when the cabinet door 6 is closed outside the storage cavity 7 , the metal plate 19 contacts the electromagnetic lock 5 .

[0037] When the cabinet door 6 is closed, the metal plate 19 is magnetically attracted and closed by the electromagnetic lock 5 .

[0038] Preferably, a damping hinge 20 is further included, and the cabinet door 6 is connected to the storage cavity 7 via the damping hinge 20 .

[0039] When the cabinet door 6 needs to be opened, the electromagnetic lock 5 can be closed. Under the action of the damping hinge 20, the cabinet door 6 will automatically open outwards, so that the renter can take away the key 4.

[0040] Preferably, the inner bottom surface of the storage box 8 is provided with a lower groove 21 for placing the handle 15 of the key 4 , and the weighing sensor 18 is arranged in the lower groove 21 .

[0041] The lower groove 21 can facilitate the placement of the handle 15 of the key 4 so that the key 4 can be stably stored in the storage slot box 8.

[0042] The present invention can also configure components such as cameras and fingerprint recognition on the cabinet 1 to identify the identity of the car renter.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
