Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle-mounted navigation, and specifically relates to a rotating base of a positioning navigation module. Background Art
[0002] Modern cars often need to be equipped with positioning and navigation modules to help drivers find the most convenient and smoothest route on the complex road network. The positioning and navigation module is embedded in the control panel of the cab, with a fixed display angle, and needs to be attached to the cab with a suction cup.
[0003] In order to facilitate the adjustment of the viewing angle, a universal ball joint is installed at the connection between the positioning navigation module and the suction cup, so that the driver can rotate the positioning navigation module by hand. However, the positioning navigation module deflects as the car bumps, especially when the car is driving on a rugged road.
[0004] When the positioning and navigation module is installed in the cab, the universal ball joint is replaced with a multi-porous rotating base, and the pin is inserted to lock it after adjusting the angle. However, the pin occupies a large space, and the multi-porous rotating base is small in size, so there are not many options for inserting the pin into the multi-porous rotating base, which makes it difficult to meet the driver's needs for fine-tuning the positioning and navigation module at a small angle. For this reason, we propose a rotating base for the positioning and navigation module. Utility Model Content
[0005] The purpose of the utility model is to provide a rotatable base for positioning and navigation module, which can rotate horizontally within a range of less than 3° to meet the needs of the driver to fine-tune the positioning and navigation module at a small angle, and can also limit the position after fine-tuning.
[0006] The technical solutions adopted in this utility are as follows:
[0007] A rotatable base of a positioning navigation module comprises a seat bracket, the middle of the front side of the seat bracket is recessed, a hinge assembly is fixed to the back side of the seat bracket, a round cover is connected to the bottom of the seat bracket through the hinge assembly, the round cover opens downwards and a plurality of inserts are distributed along a circumferential array on the inner side of the opening, the height of the inserts are all less than the height of the round cover, the central axis of the inserts are all parallel to the central axis of the round cover, a mounting ring is also axially inserted at the opening of the round cover, a plurality of limit plates are distributed along a circumferential array on the outer side of the mounting ring, one side of the limit plates extends into the interval between two adjacent inserts, a plurality of tension springs are rotatably installed inside the mounting ring, the upper ends of the tension springs are fixedly connected to the upper wall of the round cover, and when installed in a cab, the lower end of the mounting ring can be fixed downwards at a designated position of a control panel, A number of tension springs are used to tighten the round cover downward against the mounting ring, and the inserts are inserted into the gaps between two adjacent limit plates. At this time, the round cover and the mounting ring are assembled together to stably support the hinge assembly, the seat bracket and the vehicle-mounted positioning and navigation module, and the inserts and the limit plates limit the circumferential position of the round cover to prevent the round cover and the vehicle-mounted positioning and navigation module from deflecting due to the shaking of the car. When fine-tuning is required, the round cover is pulled upward by hand to lengthen the tension spring until the inserts are all higher than the limit plates, and then the round cover is rotated by hand at a certain angle to make the vehicle-mounted positioning and navigation module face the appropriate direction. Since the limit plates divide the mounting ring into partitions of no more than 3° at equal intervals, they can be rotated horizontally within a range of less than 3° to meet the driver's needs for fine-tuning the positioning and navigation module at a small angle. Then the round cover is lowered, and the inserts are reinserted into the gaps between the limit plates, and can be limited again after fine-tuning.
[0008] A suction cup is fixed on the lower end surface of the mounting ring, and the suction cup can be used to drive the mounting ring to be sucked on the control table without gluing. After disassembly, there is no residual glue, and it is relatively neat.
[0009] An alloy bearing is fixed on the inner edge of the mounting ring, and the inner ring of the alloy bearing is fixedly connected to the lower end of the tension spring. After the tension spring rotates with the round cover, the inner ring of the alloy bearing is pulled to rotate and move at an angle, which facilitates the tension spring to maintain a vertical state and be independent of each other, avoiding the tension springs from being entangled with each other.
[0010] A buffer pad is fixed on the upper wall of the round cover at a position offset from the tension spring. The buffer pad is vertically opposite to the mounting ring. When the round cover approaches the mounting ring, the buffer pad is driven to contact the mounting ring. The compressive deformation of the buffer pad is used to buffer and reduce shock, thereby alleviating hard collisions between the round cover and the mounting ring and reducing noise.
[0011] The lower ends of the inserts are all rounded. When the inserts are lowered, the arc surface of the rounded corners can be used to contact the limiting plate, and the inserts can be pushed along the arc surface to fall to both sides of the limiting plate, thereby reducing the inserts from being padded by the limiting plate.
[0012] The hinge assembly includes two arms arranged on the back of the seat bracket, and a locking bolt is inserted between the ends of the two arms that are close to each other. The other end of one of the arms is fixedly connected to the back of the seat bracket, and the other end of the other arm is fixedly connected to the middle of the upper surface of the round cover. The nut of the locking bolt is tightened to pull the two arms close together and lock them by friction. Conversely, the nut of the locking bolt is loosened to release the locking state of the two arms. The upper arm can be swung around the locking bolt to drive the vehicle-mounted positioning and navigation module to swing in the vertical plane, change the elevation angle of the vehicle-mounted positioning and navigation module, and the rotating base has a greater degree of freedom.
[0013] The technical effects achieved by this utility model are:
[0014] The utility model discloses a rotatable base of a positioning and navigation module. When it is installed in a cab, the lower end face of the mounting ring can be fixed downward at a designated position of the control panel, and a plurality of tension springs are used to tighten the round cover downward and close to the mounting ring, and the inserts are respectively inserted into the intervals of two adjacent limit plates. At this time, the round cover and the mounting ring are assembled together to stably support the hinge assembly, the seat bracket and the vehicle-mounted positioning and navigation module, and the inserts and the limit plates limit the circumferential position of the round cover to avoid the deflection of the round cover and the vehicle-mounted positioning and navigation module caused by the shaking of the car. When fine-tuning is required, the round cover is pulled upward by hand to stretch the tension spring until the inserts are all higher than the limit plates, and then the round cover is rotated by hand at a certain angle to make the vehicle-mounted positioning and navigation module face a suitable direction. Since the limit plates divide the mounting ring into partitions not greater than 3° at equal intervals, the mounting ring can be horizontally rotated within a range less than 3° to meet the driver's need to fine-tune the positioning and navigation module at a small angle, and then the round cover is lowered, and the inserts are reinserted into the intervals of the limit plates, and can be limited after fine-tuning.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0023] like Figure 1-5 As shown, a rotating base of a positioning and navigation module comprises a support 1, a depression in the middle of the front side of the support 1, the depression can hold a GARMIN 1455 vehicle-mounted positioning and navigation module, and can expose a high-precision touch screen of about 5 inches, a hinge assembly is fixed on the back side of the support 1, a round cover 2 is connected to the bottom of the support 1 through the hinge assembly, the round cover 2 opens downward and a plurality of inserts 3 are distributed along a circumferential array on the inner side of the opening, the height of the inserts 3 are all less than the height of the round cover 2, the central axis of the inserts 3 are all parallel to the central axis of the round cover 2, a mounting ring 5 is also inserted axially at the opening of the round cover 2, a plurality of limiting plates 4 are distributed along a circumferential array on the outer side of the mounting ring 5, one side of the limiting plates 4 extends into the interval between two adjacent inserts 3, a plurality of tension springs 6 are rotatably installed inside the mounting ring 5, the upper ends of the tension springs 6 are fixedly connected to the upper wall of the round cover 2, and when installed in the cab, the lower end of the mounting ring 5 can be facing downward The circular cover 2 is fixed at the designated position of the control panel, and the circular cover 2 is tightened by a plurality of tension springs 6 to press the circular cover 2 downward against the mounting ring 5, and the inserting pieces 3 are respectively inserted into the intervals of two adjacent limiting pieces 4. At this time, the circular cover 2 and the mounting ring 5 are assembled together to stably support the hinge assembly, the seat bracket 1 and the vehicle-mounted positioning and navigation module, and the inserting pieces 3 and the limiting pieces 4 limit the circular cover 2 circumferentially to prevent the circular cover 2 and the vehicle-mounted positioning and navigation module from deflecting due to the shaking of the car. When fine-tuning is required, the circular cover 2 is pulled upward by hand to lengthen the tension spring 6 until the inserting pieces 3 are all higher than the limiting pieces 4, and then the circular cover 2 is rotated by hand at a certain angle to make the vehicle-mounted positioning and navigation module face the appropriate orientation. Since the limiting pieces 4 divide the mounting ring 5 into partitions of no more than 3° at equal intervals, it can be rotated horizontally within a range of less than 3° to meet the driver's needs for fine-tuning the positioning and navigation module at a small angle, and then the circular cover 2 is put down, and the inserting pieces 3 are reinserted into the intervals of the limiting pieces 4, and can be limited after fine-tuning.
[0024] The inserting piece 3 and the limiting piece 4 can both be made of alloy material, and the strength of horizontal mutual support is high. Even if the car shakes, it can still provide stable support, especially the height of the inserting piece 3 is smaller than the height of the round cover 2. In this way, after the inserting piece 3 moves to the top of the limiting piece 4, the round cover 2 still partially covers the mounting ring 5, and the mounting ring 5 and the limiting piece 4 are used for vertical guidance, thereby reducing the degree of skewness of the round cover 2 after being pulled up.
[0025] like Figure 1 and Figure 4As shown, a suction cup 7 is fixed on the lower end surface of the mounting ring 5, and the suction cup 7 can be used to drive the mounting ring 5 to be sucked on the control table without gluing. After disassembly, there is no residual glue, and it is relatively neat.
[0026] like Figure 1 , Figure 4 and Figure 5 As shown, an alloy bearing 8 is fixed on the inner edge of the mounting ring 5, and the inner ring of the alloy bearing 8 is fixedly connected to the lower end of the tension spring 6. After the tension spring 6 rotates with the round cover 2, the inner ring of the alloy bearing 8 is pulled to rotate and move at an angle, so that the tension spring 6 can maintain a vertical state and be independent of each other, thereby preventing the tension springs 6 from being entangled with each other.
[0027] like Figure 1 and Figure 3 As shown, a buffer pad 9 is fixed on the upper wall of the round cover 2 at a position offset from the tension spring 6. The buffer pad 9 can be made of rubber material. The buffer pad 9 is vertically opposite to the mounting ring 5. After the round cover 2 approaches the mounting ring 5, the buffer pad 9 is driven to contact the mounting ring 5. The compressive deformation of the buffer pad 9 is used to buffer and absorb shock, thereby alleviating hard collisions between the round cover 2 and the mounting ring 5 and reducing noise.
[0028] like Figure 1 and Figure 3 As shown, the lower end of the insert 3 has rounded corners. When the insert 3 descends, the arc surface of the rounded corner can contact the limit plate 4, and the insert 3 is pushed along the arc surface to fall to both sides of the limit plate 4, thereby reducing the insert 3 being padded by the limit plate 4.
[0029] like Figure 1 and Figure 2 As shown, the hinge assembly includes two arms 10 arranged on the back of the seat bracket 1, and a locking bolt 11 is inserted between the ends of the two arms 10 that are close to each other. The other end of one arm 10 is fixedly connected to the back of the seat bracket 1, and the other end of the other arm 10 is fixedly connected to the middle of the upper surface of the round cover 2. Tighten the nut of the locking bolt 11 to pull the two arms 10 close together and lock them by friction. Conversely, loosen the nut of the locking bolt 11 to release the locking state of the two arms 10. The upper arm 10 can be swung around the locking bolt 11, which can drive the vehicle-mounted positioning and navigation module to swing in the vertical plane and change the elevation angle of the vehicle-mounted positioning and navigation module. The rotating base has a greater degree of freedom.
[0030] The working principle of the utility model is as follows: when installed in the cab, the lower end face of the mounting ring 5 can be fixed downward at the designated position of the control panel, and the round cover 2 can be tightened downward against the mounting ring 5 by using a plurality of tension springs 6, and the inserting pieces 3 are respectively inserted into the intervals between two adjacent limiting pieces 4. At this time, the round cover 2 and the mounting ring 5 are assembled together to stably support the hinge assembly, the seat bracket 1 and the vehicle-mounted positioning and navigation module, and the inserting piece 3 and the limiting piece 4 limit the circumferential position of the round cover 2 to prevent the round cover 2 and the vehicle-mounted positioning and navigation module from deviating due to the shaking of the car. When fine-tuning is needed, pull the round cover 2 upward by hand to lengthen the tension spring 6 until the insert pieces 3 are all higher than the limit pieces 4, and then rotate the round cover 2 by hand at a certain angle to make the vehicle-mounted positioning and navigation module face the appropriate direction. Since the limit pieces 4 divide the mounting ring 5 into partitions of no more than 3° at equal intervals, it can be rotated horizontally within a range of less than 3° to meet the driver's needs for fine-tuning the positioning and navigation module at a small angle. Then put down the round cover 2, reinsert the insert pieces 3 into the interval of the limit pieces 4, and it can be limited after fine-tuning.
[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
