DETAILED DESCRIPTION

[0031] Embodiment 1:

[0032] See also Figure 1 to Figure 2 The embodiment of the present invention provides an on-board unit OBU device, which is mainly used to realize the rapid activation of the OBU device and confirm the successful activation. The device includes an OBU device 1 bonded to the windshield, and a tag card 2 is inserted into the right side of the OBU device 1. The tag card 2 and the OBU device 1 are two components of the OBU device. At the same time, an identification module 102 corresponding to the position after the tag card 2 is inserted is fixedly installed inside the OBU device, which is used to identify the type of the tag card 2 and enable the OBU device to work.

[0033] In this embodiment, the tag card 2 may be a debit card, which, together with the OBU device 1 and the identification module 102, are all existing mature technologies and will not be described in detail here.

[0034] Furthermore, a cavity 101 is provided inside the OBU device 1, and a clamping component 4 corresponding to the position of the tag card 2 and a control component 3 for driving the clamping component 4 to move are provided inside the cavity 101. When the tag card 2 is inserted into the OBU device 1, the clamping component 4 can be used to effectively limit the position, and the control component 3 and the clamping component 4 can realize the rapid movement of the tag card 2 relative to the OBU device 1, and the movement of the tag card 2 can be carried out quickly with one hand.

[0035] See also Figures 1 to 4In this embodiment, preferably: the control component 3 includes a partition 302 that is slidably matched with the cavity 101, and a guide column 301 protruding relative to the OBU device 1 is fixedly installed on the left side of the partition 302, and the partition 302 can be moved in the cavity 101 by pressing the protruding guide column 301. Two support rods 303 for driving the clamping component 4 to move are fixedly installed on the right side of the partition 302, and a first spring 304 is fixedly installed between the right side of the partition 302 and the cavity wall of the cavity 101, which is used for the automatic reset of the partition 302 after moving along the cavity 101.

[0036] Furthermore, the clamping assembly 4 includes a base 401 that moves synchronously with the support rod 303. The base 401 can be fixedly connected or rotatably connected or plug-in engaged with the support rod 303. The base 401 is designed to be U-shaped as a whole and a rubber layer 402 for limiting the label card 2 is fixedly installed inside it. The rubber layer 402 is also U-shaped as a whole due to the U-shaped base 401; when the label card 2 is inserted into the OBU device 1, it enters the rubber layer 402 and is clamped.

[0037] In the above structure, the left side of the partition 302 can fit with the cavity wall on the left side of the cavity 101, so that the partition 302 and the base 401 can no longer be pushed to the left, so that when the tag card 2 is inserted to the point where it can no longer move to the left, the tag card 2 has entered the rubber layer 402 to complete the limit, and has automatically corresponded with the identification module 102. Even if the left side of the partition 302 is not fitted, the tag card 2 will abut against the card slot wall of the OBU device 1 after it moves to the left.

[0038] When in use, first insert the tag card 2 from the right side of the OBU device 1, so that the left side of the tag card 2 enters the rubber layer 402 to complete the limit and automatically correspond to the identification module 102. Then press the left guide column 301 twice with one hand, and drive the tag card 2 to move back and forth quickly twice relative to the OBU device 1 through the side plate 4001, the support rod 303, the base 401 and the first spring 304 (that is, the tag card 2 is quickly plugged and unplugged twice relative to the OBU device 1, and the tag card 2 will not leave the OBU device 1 during plugging and unplugging). In this way, the Bluetooth function of the OBU device 1 can be turned on, and then the mobile phone Bluetooth is turned on for connection identification. The activation can be completed by taking the corresponding photo and uploading it for review and approval. After successful activation, press the left guide column 301 twice with one hand again, drive the tag card 2 to be quickly plugged and unplugged twice again relative to the OBU device 1, and the activation state of the OBU device can be verified.

[0039] In summary, through the cooperation of the guide column 301, the partition plate 302, the base 401 and the first spring 304 and other structures, the tag card 2 can be driven to form a quick plug-in and pull-out relative to the OBU device 1, thereby facilitating the quick start of the Bluetooth of the OBU device 1 and the quick verification after successful activation, thereby facilitating the quick use of the OBU device. The overall solution can be completed with one hand, and the hand is pressed on the OBU device 1 to drive the guide column 301 to move through the fingers. When plugging and unplugging the tag card 2, the OBU device 1 can also be limited, which can avoid the displacement of the OBU device 1 when plugging and unplugging the tag card 2 and causing subsequent falling off; the overall operation is simple and applicable to a wider range of people. When in use, it can also ensure the effective limit of the tag card 2 to avoid the falling off of the tag card 2, and it is more practical.

[0040] Embodiment 2:

[0041] See also Figures 1 to 6 On the basis of the first embodiment, in order to realize the protection of the tag card 2, the relationship between the guide post 301 and the partition plate 302 is improved: the guide post 301 is set on the right side of the OBU device 1 and slides with it, so that the guide post 301 and the tag card 2 form the same side. And the guide post 301 drives the partition plate 302 to move along the cavity 101 through the moving component 5. When the guide post 301 is pressed relative to the OBU device 1, the moving component 5 can also drive the clamping component 4 and the tag card 2 to move back and forth quickly relative to the OBU device 1.

[0042] See also Figures 1 to 7 In this embodiment, preferably: the moving component 5 includes a gear 502 rotatably connected to the OBU device 1 and an upper rack 501 and a lower rack 503 that are transmission-connected to the gear 502, the upper rack 501 is fixedly connected to the partition 302 to form a synchronous movement, and the lower rack 503 is slidably connected to the OBU device 1 and forms a synchronous movement with the guide column 301.

[0043] The OBU device 1 has a groove 103 in communication with the cavity 101, which is used to accommodate the gear 502, the upper rack 501 and the lower rack 503. The groove 103 is arranged below the base 401, and the two will not interfere with each other.

[0044] In the above structure, the end of the guide column 301 away from the OBU device 1 protrudes relative to the side of the label card 2 away from the OBU device 1, or the two remain flush; on this basis, the left side of the partition 302 may not be in contact with the left wall of the cavity 101, and a certain space is reserved between the two. When the OBU device 1 falls to the ground and the right side touches the ground first, it can be combined with the first spring 304 to form a buffer.

[0045] The non-fitting design between the partition 302 and the cavity 101 will not affect the installation of the tag card 2, because when the tag card 2 is inserted from right to left, even if the base 401 is pushed to move leftward, it will abut against the card slot wall of the OBU device 1 where the tag card 2 is placed.

[0046] Furthermore, in order to ensure that the left or right side of the OBU device 1 touches the ground first when it lands, the weight of the guide post 301 can be increased, so that the weight of the side where the guide post 301 is installed becomes heavier. After landing, the side facing downward will naturally touch the ground first due to gravity. The number of guide posts 301 can also be increased, so that one is arranged on each side, so that when the left or right side lands first, it can be buffered by the first spring 304. Of course, the weights of the two guide posts 301 need to be designed to be different. This design also facilitates the position adjustment of the tag card 2 because there are guide posts 301 on each side.

[0047] Furthermore, when the guide post 301 is only arranged on the right side of the OBU device 1, the number of the guide posts 301 can be increased on the right side and arranged symmetrically along the tag card 2, which can improve the buffering effect on the OBU device 1 and the tag card 2.

[0048] In this embodiment, the position of the guide post 301 is based on the OBU device 1 being located at the front side of the tag card 2, and can be adjusted accordingly as needed during actual use.

[0049] When in use, the effective position limitation of the tag card 2 can be achieved through the structures such as the guide column 301 and the base 401, and the tag card 2 can be driven to form a quick plug-in and pull-out relative to the OBU device 1. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that pressing the guide column 301 is to apply force from the right side (the thumb can press the OBU device 1), which can drive the guide column 301 to move to the left and drive the lower rack 503 to move synchronously, and then drive the upper rack 501, the partition 302 and the base 401 to move to the right through the gear 502. Under the action of the first spring 304, the tag card 2 can still be driven to form a quick plug-in and pull-out relative to the OBU device 1, and the Bluetooth startup and activation verification functions can also be completed.

[0050] When the OBU device 1 falls to the ground accidentally (the adhesive loses its adhesive force or the windshield is damaged), the right side of the OBU device 1 will touch the ground first. At this time, the guide post 301 will first contact the label card 2 with the ground and cooperate with the first spring 304 to achieve overall buffering.

[0051] In Example 1, the tag card 2 can be quickly plugged in and out of the OBU device 1 through structures such as the guide column 301 and the partition plate 302. However, the guide column 301 applies force on different sides of the tag card 2 to drive the tag card 2 to move. When the OBU device 1 accidentally falls and the tag card 2 faces downward, there will be significant collision damage between the tag card 2 and the OBU device 1, which has certain usage limitations.

[0052] Compared with the first embodiment, the guide post 301 is arranged at the same side as the tag card 2 through the cooperation of the guide post 301, the partition plate 302, the upper rack 501 and the first spring 304, so that when the OBU device 1 falls to the ground accidentally, the guide post 301 can first contact the ground to achieve the overall buffering of the OBU device 1 and the tag card 2, thereby reducing the collision damage between the tag card 2 and the OBU device 1, and extending the service life of the tag card 2 and the OBU device 1. The overall design is combined with the position of the guide post 301, which will not affect the reciprocating movement of the tag card 2, and the adjustment of the tag card 2 is also simple and convenient, and the applicability is stronger.

[0053] Embodiment three:

[0054] See also Figures 1 to 9 On the basis of the second embodiment, in order to facilitate the removal of the label card 2 and ensure the limiting effect, the guide column 301 is further improved: at this time, the guide column 301 is circular and can also rotate on its own based on the sliding of the OBU device 1; and a rotating component 6 for driving the two support rods 303 to rotate synchronously is also provided between the guide column 301 and the partition 302. When the guide column 301 is rotated, the support rod 303 can be driven to rotate synchronously through the rotating component 6.

[0055] Further, such as Fig. 9 As shown, the base 401 includes a side plate 4001 that moves synchronously with the support rod 303 and two horizontal plates 4002 that slide up and down with the side plate 4001, and the rubber layer 402 is fixedly installed on the side plate 4001 and the two horizontal plates 4002 respectively; a second spring 4003 is fixedly installed between the two horizontal plates 4002, and under the action of the second spring 4003, the two horizontal plates 4002 have a tendency to approach each other.

[0056] Among them, a long groove 4004 for the sliding of the cross plate 4002 is opened on the surface of the cross plate 4002 away from the support rod 303, and the second spring 4003 can also be arranged in the groove 103. The advantage of this design is that it will not affect the arrangement of the rubber layer 402 on the cross plate 4002, and will not interfere with the second spring 4003; the size of the long groove 4003 is smaller than the rubber layer 402 on the side plate 4001, so as not to affect the placement of the corresponding rubber layer 402, so that the rubber layer 402 can be smoothly fixed on the side plate 4001.

[0057] Furthermore, the support rod 303 passes through the base 401 and is rotatably connected thereto, and its end away from the partition 302 extends to the interior of the base 401 and is fixedly mounted with a protrusion 305 that abuts against the two cross plates 4002. The protrusion 305 also extends into the groove 103 and will not affect the placement of the rubber layer 402. The support of the protrusion 305 allows the two cross plates 4002 to maintain different opening states.

[0058] Among them, the protrusion 305 and the second spring 4003 are designed to be offset, and there will be no interference between the two. The opening of the long groove 4004 here not only facilitates the sliding of the cross plate 4002, but also provides space for the placement of the protrusion 305 and the second spring 4003. The protrusion 305 is placed in the long groove 4004 to support the rubber layer 402 on the side plate 4001, thereby preventing the left side of the label card 2 from squeezing the rubber layer 402 on the side plate 4001, causing the rubber layer 402 to deform.

[0059] See also Figures 1 to 10 In this embodiment, preferably: the protrusion 305 can be a polygon with an even number of sides, such as a quadrilateral, hexagon, octagon, etc., and the above shape is an incompletely symmetrical design; so that the protrusion 305 can keep the state of the horizontal plate 4002 stable when acting on the two horizontal plates 4002, so that the protrusion 305 will not deflect arbitrarily under the action of the second spring 4003; and the more sides there are, the easier it is for the guide column 301 to rotate. If the protrusion 305 is not designed as above, the rotation friction between the guide column 301 and the OBU device 1 can also be increased, so that the rotation of the guide column 301 requires a certain force to be realized.

[0060] Furthermore, the rotating assembly 6 includes an outer cylinder 602 rotatably connected to the partition 302 and an inner rod 601 assembled with the outer cylinder 602 in a key-axis manner. The inner rod 601 can rotate synchronously with the outer cylinder 602 and can slide based on the outer cylinder 602. The inner rod 601 and the guide column 301 and the outer cylinder 602 and the two support rods 303 are connected by a belt drive 603. At this time, the belt drive 603 can be a belt drive 603 or a chain drive 603, so that the synchronous rotation of the guide column 301, the inner rod 601, the outer cylinder 602 and the support rod 303 can be achieved.

[0061] In the above structure, the opening of the groove 103 is also conducive to the placement of the inner rod 601 and the outer cylinder 602 , and the belt transmission 603 between the outer cylinder 602 and the two support rods 303 will not interfere with the first spring 304 .

[0062] When in use, the effective position limiting and quick plugging of the tag card 2 are realized through the structures such as the guide column 301 and the base 401, and the overall buffering when the tag card 2 falls accidentally is realized through the setting of the guide column 301 and the tag card 2. The working process and effect of this part are the same as those in the second embodiment, and will not be repeated here. The difference is that when the self-rotating guide column 301 based on the OBU device 1 can drive the two support rods 303 to rotate synchronously through the belt transmission 603, the inner rod 601 and the outer cylinder 602, the support rod 303 drives the protrusion 305 to rotate in the long groove 4004 and cooperates with the second spring 4003 to realize the sliding of the cross plate 4002 based on the side plate 4001, so that the two cross plates 4002 are relatively close / far away, thereby changing the spacing between the rubber layers 402 on the two cross plates 4002, increasing the spacing can facilitate the insertion of the tag card 2 in the initial state, and reducing the spacing after insertion can ensure the clamping and position limiting of the tag card 2. At the same time, when the tag card 2 needs to be removed later, the spacing can be increased, and it can be easily removed from the OBU device 1.

[0063] In the second embodiment, the guide column 301, the first spring 304 and other structures can realize the overall buffering in case of accidental falling. However, due to the existence of the rubber layer 402, it is necessary to increase the force when taking out and placing the label card 2. At the same time, it is also necessary to increase the force when inserting and placing the label card 2 so that the label card 2 can enter the rubber layer 402 to ensure clamping, which has certain limitations in use.

[0064] Compared with the second embodiment, the initial spacing adjustment of the two rubber layers 402 can be achieved through the cooperation of the structures such as the inner rod 601, the outer cylinder 602, the horizontal plate 4002 and the protrusion 305. Increasing the spacing can be beneficial to the initial placement of the tag card 2 and the easy removal at a later time. Reducing the spacing can be beneficial to the clamping and limiting of the tag card 2 after placement. The horizontal plate 4002 drives the movement of the rubber layer 402 and combines with the second spring 4003 to adjust the clamping force of the tag card 2, so that the limiting effect of the tag card 2 is appropriate. The overall solution is combined with the design of the base 401, which is convenient for the corresponding use of the operator, improves the overall experience of the OBU device, and meets more needs in actual use.

[0065] Furthermore, based on the fact that both sides of the OBU device 1 have guide posts 301, in order to further facilitate the rotation of the protrusion 305 to adjust the distance between two adjacent rubber layers 402, the guide post 301 on the right side of the OBU device 1 maintains its initial position relative to the tag card 2, and the guide post 301 on the left side is as follows: Figure 1 As shown in FIG. 2 , the left guide post 301 is located in the middle of the left side of the OBU device 1, and extends into and penetrates the partition plate 302 and is then fixedly connected to the outer cylinder 602. In this way, the guide post 301 on either side of the OBU device 1 can be rotated to drive the protrusion 305 to rotate to adjust the distance between the two rubber layers 402, so that the operator has more choices.
