Description

Technical Field

[0001] The utility model relates to the technical field of navigation equipment, in particular to a torsion-type volume adjustment navigator. Background Art

[0002] With the continuous progress of society, people's activities are also expanding. It is difficult to meet people's travel needs by relying solely on their own memory or traditional ways of guiding such as paper maps. Therefore, electronic navigation devices have become one of the indispensable travel aids in modern society. For example, a navigator is one of the necessary equipment when hiking or driving long distances.

[0003] When the existing fifth-generation navigation is in use, some of it uses a knob to adjust the volume. During use, it is normal to put the navigation device in a backpack or install it in the car. If the volume adjustment part is accidentally touched due to squeezing or collision, it will become smaller or even disappear, and the user often cannot find it in time. At the same time, during the application process, the navigation sound is not always maintained, and it will only sound when encountering intersections or in some situations. If the above situation occurs at this time, the user will not turn in time or understand the situation ahead, which will affect the use effect. In severe cases, it may even cause the user to make mistakes. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] See also Figure 1-Figure 5 As shown, the utility model is a torsion volume adjustment navigator, comprising a navigator body 1, which is the same as the existing fifth-generation navigation device, and the navigator body 1 will emit a short prompt sound of corresponding size at each gear position when adjusting the volume;

[0029] like Figure 4 and Figure 5As shown, a volume adjustment knob body 3 is installed on both sides of one end of the navigator body 1, and a guide member 6 is installed at one end inside the volume adjustment knob body 3, a movable kit 7 is sleeved on the outer side of the guide member 6, and a spring 8 is connected between the movable kit 7 and the guide member 6, an extrusion plate 9 is installed at one end of the bottom of the movable kit 7 close to the navigator body 1, an outer protection knob 10 is installed at one end of the movable kit 7 away from the navigator body 1, and an annular groove 11 is opened at one end of the outer protection knob 10 close to the navigator body 1, and a first gear ring 12 is installed on the inner side wall of the annular groove 11, and the guide member 6 is provided with a plurality of springs. The cross-sectional shape is square, and the guide member 6 and the movable set 7 form a sliding structure. The outer side of the outer protection knob 10 is provided with anti-slip grooves, and the outer protection knob 10 and the volume adjustment knob body 3 form a sliding structure, so that the outer protection knob 10 and the volume adjustment knob body 3 cannot rotate relative to each other, and then when the rotation of the outer protection knob 10 is restricted, the rotation of the volume adjustment knob body 3 is also restricted, thereby preventing the volume from being accidentally reduced. At the same time, in actual application, one group 3 and 10 can be set to the above design, and the other group can be designed to be the same appearance only as decoration;

[0030] like Figure 4 and Figure 5 As shown, a limiting mechanism for limiting the rotation of the outer protection knob 10 is provided on the navigator body 1, and the limiting mechanism includes two sets of fixing rings 13, the fixing rings 13 are located inside the corresponding annular grooves 11, and the fixing rings 13 are fixed on the navigator body 1, and a second toothed ring 14 is installed on the outer side of the fixing ring 13, the central axis of the second toothed ring 14 coincides with the central axis of the first toothed ring 12, and the second toothed ring 14 is meshed with the first toothed ring 12, so that when the sound of the navigator body 1 does not need to be adjusted, the rotation of the outer protection knob 10 will be limited by the cooperation of the first toothed ring 12 and the second toothed ring 14, and when adjusting, it is only necessary to pull the outer protection knob 10 to release the meshing of the first toothed ring 12 and the second toothed ring 14;

[0031] Example 2

[0032] like Figure 1 , Figure 4 and Figure 5As shown, a buzzer 2 is installed at one end of the navigator body 1 close to the volume adjustment knob body 3. The timbre of the buzzer 2 is different from that of the navigator body 1, and the sound emitted by the buzzer 2 is of a constant size. A mounting plate 4 is installed on the inner side wall of the volume adjustment knob body 3, and a squeezing button 5 is installed at one end of the mounting plate 4 close to the navigator body 1. The squeezing button 5 is electrically connected to the buzzer 2, so that when the outer protection knob 10 is pulled to adjust the volume, the squeezing plate 9 squeezes the squeezing button 5 to make the buzzer 2 emit a sound, so as to prompt the staff to start adjusting. At the same time, when driving, the staff can compare the short prompt sound emitted by the navigator body 1 at each gear when adjusting the volume and the sound of the buzzer 2 to more accurately determine the size of the sound, thereby increasing driving safety. The sound size of the buzzer 2 can be the same as the sound size emitted by the median gear of the navigator body 1. Further, in the complex situation of accidental touch, when the outer protection knob 10 is hooked, the buzzer 2 can also continue to emit sound to prompt the user.

[0033] The working principle of the utility model is as follows: the navigation device body 1 can be turned on for navigation. When the volume needs to be adjusted, the staff can hold a set of outer protection knobs 10 and pull them away from the navigation device body 1 until the squeeze button 5 is squeezed, and the buzzer 2 emits a sound of a constant volume and a different tone from the navigation device body 1. At this time, the first gear ring 12 is released from the meshing connection with the second gear ring 14, and the rotation restriction of the outer protection knob 10 is released. At this time, the outer protection knob 10 is rotated to drive the volume adjustment knob body 3 to rotate to adjust the volume of the navigation device body 1. During the adjustment process, the navigation device body 1 will emit a short sound at each sound gear. The staff can adjust the sound according to the sound volume displayed on the display screen of the navigation device body 1. At the same time, the sound volume can be adjusted by comparing it with the sound emitted by the buzzer 2 in driving and other situations, without the need to check the display screen of the navigation device body 1 in driving and other situations.

[0034] During use, when the outer and inner protective knobs 10 of the device are squeezed and accidentally touched in a backpack or a car body, the first tooth ring 12 and the second tooth ring 14 can cooperate with each other to limit the rotation of the outer protective knob 10, thereby limiting the rotation of the volume adjustment knob body 3, preventing the volume from decreasing or even disappearing on its own. When the outer protective knob 10 is hooked up by other objects due to complex circumstances, the squeezing button 5 is squeezed by the squeezing plate 9, and the buzzer 2 emits a continuous sound, thereby promptly and continuously reminding the user that the sound is at risk of being accidentally touched and changed, which is convenient for the staff to make adjustments.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
