Description

Technical Field

[0001] This utility model relates to the field of vehicle navigation technology, specifically a vehicle navigation device that is easy to maintain. Background Technology

[0002] Car navigation systems, through the collaborative work of in-vehicle GPS and electronic maps, can conveniently and accurately provide drivers with the shortest or fastest route to their destination, becoming an indispensable assistant for drivers. Currently, driving schools generally install more accurate car navigation systems on the roof of their vehicles used for road training. However, because these navigation systems are installed on the exterior of the vehicle and are exposed to wind and rain for a long time, their failure rate is relatively high. Therefore, they need to be maintained regularly to ensure normal operation.

[0003] Upon investigation, a utility model patent (publication number: CN213515683U) discloses an easy-to-maintain vehicle navigation device, including a fixing plate and a vehicle navigation device. Fixing bolts are provided through both ends of the fixing plate and are fixedly connected to the roof of the vehicle. A cylinder is fixedly welded to the middle of the fixing plate, and a cylinder is inserted into the inside of the cylinder. The cylinder and the cylinder are fixedly connected by a fixing mechanism. The fixing mechanism includes a limiting groove formed on the outer wall of the cylinder. A limiting nut is threadedly connected to the side wall of the cylinder. One end of the limiting nut passes through the side wall of the cylinder and is inserted into the limiting groove. The outer wall of the limiting nut contacts the inner wall of the limiting groove. A quick positioning mechanism is provided between the cylinder and the cylinder. A support column is fixedly welded to the top of the cylinder.

[0004] In the aforementioned patent, a fixing plate is fixedly installed on the roof of the vehicle, and a cylinder is fixedly welded onto the fixing plate. The vehicle navigation device is fixedly connected to the support column, and the support column is fixedly connected to the cylinder. The cylinder and the cylinder are connected by a fixing mechanism, which is a detachable connection method. This allows the vehicle navigation device, support column, and cylinder to be removed from the cylinder for maintenance. However, each time disassembly and installation are performed, the limiting nut must be rotated. This operation is relatively cumbersome, which not only prolongs the operation time but also increases the difficulty of disassembly because the limiting nut is exposed and susceptible to corrosion and rust.

[0005] Therefore, this utility model provides an easy-to-maintain vehicle navigation system to solve the above problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides an easy-to-maintain vehicle navigation system, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the vehicle navigation device includes a fixing plate 1, a limiting cylinder 2 fixedly installed on the fixing plate 1, a fixing cylinder 3 fixedly installed inside the limiting cylinder 2, a vehicle navigation device body 4 set above the limiting cylinder 2, a support column 5 fixedly installed at the bottom of the vehicle navigation device body 4, and an installation and removal mechanism set inside the limiting cylinder 2 for quick installation and removal of the vehicle navigation device body 4.

[0019] The loading and unloading mechanism includes a telescopic rod 6 fixedly installed on the inner wall of the limiting cylinder 2, an insert 7 fixedly installed on the movable end of the telescopic rod 6, a first spring 8 sleeved on the side surface of the telescopic rod 6, a sliding groove 9 opened inside the limiting cylinder 2, a control rod 10 slidably installed inside the sliding groove 9, an anti-slip ring 11 slidably installed on the side surface of the limiting cylinder 2, an inclined groove 12 opened inside the insert 7 for the control rod 10 to slide, and a slot 13 opened on the side surface of the support column 5 for the insert 7 to be inserted into.

[0020] The support column 5 is slidably installed inside the fixed cylinder 3, and the insert block 7 penetrates through the fixed cylinder 3.

[0021] One end of the first spring 8 is fixedly connected to the inner wall of the limiting cylinder 2, and the other end of the first spring 8 is fixedly connected to one side of the insert block 7. One end of the control rod 10 is fixedly connected to the inner wall of the anti-slip ring 11.

[0022] When using this car navigation system, first, the mounting plate 1 is installed in a suitable position. Then, the car navigation system body 4 is slidably installed into the inside of the mounting cylinder 3 via the support column 5. During the sliding installation process, the bottom of the support column 5 will contact the inclined surface of the insert 7, and then push the insert 7 to move. The insert 7 drives the telescopic rod 6 to extend and retract. At the same time, the first spring 8 is compressed and generates elastic force. When the support column 5 slides to the suitable position, the slot 13 corresponds to the position of the insert 7. At this time, under the action of the elastic force of the first spring 8, the insert 7 will quickly insert into the inside of the slot 13, thereby... The vehicle navigation unit 4 is quickly installed into the limiting cylinder 2, completing the installation of the vehicle navigation unit. When it is necessary to remove the vehicle navigation unit 4, simply pull down the anti-slip ring 11. The anti-slip ring 11 drives the control rod 10 to move. The control rod 10 slides inside the inclined groove 12, thereby pushing the insert 7 to move and disengage the insert 7 from the inside of the slot 13. At this time, the vehicle navigation unit 4 can be taken out from the inside of the limiting cylinder 2, completing the disassembly of the vehicle navigation unit. The installation and disassembly of the vehicle navigation unit 4 are more convenient, thus facilitating the maintenance of the vehicle navigation unit 4.

[0023] In order to reassemble the various parts after disassembling the vehicle navigation unit body 4, such as... Figure 1 , Figure 3 , Figure 4 and Figure 6As shown, a second spring 14 is sleeved on the side surface of the fixed cylinder 3, and a pad 15 is slidably connected to the side surface of the fixed cylinder 3.

[0024] One end of the second spring 14 is fixedly connected to the bottom inner wall of the limiting cylinder 2, and the other end of the second spring 14 is fixedly connected to the bottom of the pad 15. The end of the control rod 10 away from the anti-slip ring 11 is in contact with the top of the pad 15.

[0025] When using this car navigation system, during the disassembly of the main body 4, pulling down the anti-slip ring 11 causes the control rod 10, which is fixedly connected to it, to descend synchronously, thereby pressing down the pad 15 and the second spring 14. After the main body 4 is disassembled, the control rod 10 loses the tension of the anti-slip ring 11. At this time, under the action of the elastic force of the second spring 14, the pad 15 will drive the control rod 10 to reset. The control rod 10 slides inside the inclined groove 12, thereby driving the insertion block 7 to move and reset, so that the main body 4 can be installed next time. This ensures the reset effect of each part and avoids the problem of parts being lost or misaligned, further improving the convenience of installing and disassembling the main body 4, and also making it easier for users to maintain the main body 4.

[0026] Furthermore, to ensure the stability of the car navigation device itself 4 during use, such as... Figure 1 , Figure 2 and Figure 3 As shown, a support rod 16 is fixedly connected to the side surface of the limiting cylinder 2. Multiple support rods 16 are provided and are arranged in a ring array on the side surface of the limiting cylinder 2. One side of the multiple support rods 16 is in contact with the side surface of the vehicle navigation device body 4. Fixing bolts 17 are screwed into the inside of the fixing plate 1.

[0027] When in use, the fixing plate 1 can be fixed to the installation position by rotating the fixing bolt 17. At the same time, since the support rods 16 are distributed in a ring array on the side surface of the limiting cylinder 2, and one side of multiple support rods 16 is in contact with the side surface of the vehicle navigation body 4, the vehicle navigation body 4 can be supported, which further improves the stability of the vehicle navigation body 4 during use, avoids the problem of the vehicle navigation body 4 becoming loose or damaged due to bumps during vehicle driving, extends the service life of the vehicle navigation body 4, and also improves the driving safety of users.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
