Description

Technical Field

[0001] The present invention relates to the technical field of positioning devices, and in particular to a Bluetooth beacon. Background Art

[0002] A Bluetooth beacon is a piece of hardware used to locate objects. The most commonly used algorithm is the triangular centroid positioning algorithm, which calculates the specific location of the object to be located based on the distance between the object to be located and three Bluetooth beacons with known locations.

[0003] However, the Bluetooth beacon in the prior art only has a positioning function and its function is relatively simple. Summary of the invention

[0004] The invention discloses a Bluetooth beacon, which is used to solve the technical problem that the existing Bluetooth beacon has a relatively single function.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A Bluetooth beacon includes: a bottom plate, an inner shell, a circuit board, an outer shell and a safety mark; wherein:

[0007] The inner shell is in a groove-shaped structure, the bottom plate is detachably connected to the open end of the inner shell, and the circuit board is arranged in the inner shell and fixed relative to the bottom plate;

[0008] The outer shell is a groove-shaped structure, the outer shell is sleeved on the outer side of the inner shell, and is detachably connected to the inner shell or the bottom plate;

[0009] The safety mark is arranged on a side of the outer shell facing away from the inner shell.

[0010] In the above-mentioned Bluetooth beacon, the inner shell and the bottom plate are detachably connected to encapsulate the circuit board inside. At the same time, the circuit board and the bottom plate are relatively fixed to prevent the circuit board from shaking. By sleeve- ing the outer shell on the outside of the inner shell, the safety mark is arranged on the side of the outer shell facing away from the inner shell. In this way, in addition to its own positioning function, the Bluetooth beacon can also serve as a safety reminder to the outside through the safety mark. Moreover, since the outer shell is detachably connected to the inner shell or the bottom plate, when the safety mark needs to be replaced, there is no need to remove the inner shell. The safety mark can be replaced by separating the outer shell from the inner shell, which saves time and effort. At the same time, it avoids the impact on the operating stability of the circuit board in the inner shell caused by frequent opening of the inner shell.

[0011] Optionally, the Bluetooth beacon further comprises a power supply, and the power supply is installed on a side of the circuit board away from the bottom plate;

[0012] The inner shell has a first window at a position opposite to the power source.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Please refer to Figures 1 to 4 :

[0030] The Bluetooth beacon provided in the embodiment of the present application includes: a base plate 10, an inner shell 30, a circuit board 20, an outer shell 40 and a safety mark 50; wherein,

[0031] The inner shell 30 is a groove-shaped structure, the bottom plate 10 is detachably connected to the open end of the inner shell 30, and the circuit board 20 is arranged in the inner shell 30 and fixed relative to the bottom plate 10; wherein the circuit board 20 can be directly fixed to the bottom plate 10, or can be as follows Figure 1 and Figure 2 , the circuit board 20 is fixed to the four corners of the inner shell 30 by fasteners such as screws 21;

[0032] The outer shell 40 is a groove-shaped structure, and the outer shell 40 is sleeved on the outer side of the inner shell 30 and is detachably connected to the inner shell 30 or the bottom plate 10;

[0033] The safety mark 50 is disposed on a side of the outer shell 40 facing away from the inner shell 30 .

[0034] In the above-mentioned Bluetooth beacon, the inner shell 30 and the bottom plate 10 are detachably connected to encapsulate the circuit board 20 inside. At the same time, the circuit board 20 and the bottom plate 10 are relatively fixed to prevent the circuit board 20 from shaking. By sleeve-mounting the outer shell 40 on the outside of the inner shell 30, the safety mark 50 is arranged on the side of the outer shell 40 away from the inner shell 30. In this way, in addition to its own positioning function, the Bluetooth beacon can also serve as a safety reminder to the outside through the safety mark 50. Moreover, since the outer shell 40 is detachably connected to the inner shell 30 or the bottom plate 10, when the safety mark 50 needs to be replaced, there is no need to remove the inner shell 30. The safety mark 50 can be replaced by separating the outer shell 40 from the inner shell 30, which saves time and effort. At the same time, it avoids the impact on the operating stability of the circuit board 20 and the like in the inner shell 30 due to frequent opening of the inner shell 30.

[0035] In a specific embodiment, reference Figure 2The Bluetooth beacon also includes a power supply 23, which is mounted on the side of the circuit board 20 away from the bottom plate 10; the inner shell 30 has a first window 32 at a position opposite to the power supply 23. Figure 2 In the figure, the inner shell 30 has a first cover plate 33 and a first enclosure 34 extending along the edge of the first cover plate 33. The first cover plate 33 is opposite to the bottom plate 10. A first window 32 is provided on the first cover plate 33 at a position opposite to the power source 23. In this way, after removing the outer shell 40, the user can directly replace the power source 23 through the first window 32.

[0036] In another specific embodiment, the housing 40 has a second window 42 at a position opposite to the power source 23, and the safety mark 50 covers the second window 42 and is detachably connected to the housing 40. Figure 2 The outer shell 40 includes a second cover plate 44 and a second enclosure plate 45 extending along the edge of the second cover plate 44. When the outer shell 40 is assembled on the inner shell 30, the second cover plate 44 is arranged opposite to the first cover plate 33, and the second enclosure plate 45 extends around the outer side of the first enclosure plate 34. A second window 42 is provided at a position where the second cover plate 44 is opposite to the power source 23. The safety mark 50 covers the second window 42 and is detachably connected to the outer shell 40. In this way, when the power source 23 needs to be replaced, it is not necessary to remove the outer shell 40, and it is only necessary to remove the safety mark 50 from the second window 42, which is more convenient and easy. In the specific setting, the shape and size of the second window 42 can be the same as the shape and size of the safety mark 50 to ensure that the safety mark 50 can be embedded in the second window 42. For example, the safety mark 50 is arrow-shaped and the second window 42 is also arrow-shaped. In the event of a disaster, it is to indicate that people should take refuge in a designated direction. The safety mark 50 is snap-fitted with the outer shell 40. Specifically, the safety mark 50 and the edge of the second window 42 can be snap-fitted, or can be detachably fixed by other means.

[0037] In addition, the safety mark 50 may also be fixedly connected to the housing 40 , and when the power supply 23 is replaced, the housing 40 and the safety mark 50 are removed together.

[0038] In a specific embodiment, the safety mark 50 is provided with a power limit groove 51 on one side facing the power source 23. When the safety mark 50 is assembled on the housing 40, the power limit groove 51 passes through the second window 42 and is buckled on the power source 23. Figure 2 The circuit board 20 has two rows of batteries as a power source 23. Figure 1 A power limiting groove 51 corresponding to the two rows of batteries is formed on the side of the safety mark 50 facing the power supply 23 through the surrounding wall. When the Bluetooth beacon is in the assembled state, the two rows of batteries are buckled into the two power limiting grooves 51 one by one to limit and fix the power supply 23.

[0039] In the specific setting, the Bluetooth beacon also includes a power base 22 arranged on the circuit board 20, and the power supply 23 is installed on the power base 22; when the safety logo 50 is assembled on the shell 40, the side wall of the power limit groove 51 is clamped with the power base 22. By clamping the side wall of the power limit groove 51 with the power base 22, the side wall of the power limit groove 51 can be fixed at the same time, thereby improving the fixing effect of the safety logo 50 and the power supply 23.

[0040] Also refer to Figure 3 and Figure 4 The edge of the bottom plate 10 has a first fixing wing 11, and the first fixing wing 11 has a first positioning hole. The outer edge of the opening end of the inner shell 30 has a second fixing wing 31 opposite to the first fixing wing 11, and the second fixing wing 31 is provided with a second positioning hole opposite to the first positioning hole;

[0041] In addition, the Bluetooth beacon further includes a first fastener 33, which is used to penetrate a corresponding set of first positioning holes and second positioning holes to relatively fix the first fixed wing 11 and the second fixed wing 31, and simultaneously fix the inner shell 30 and the outer shell 40 to an installation position such as a wall. The first fastener 33 can be a screw or a bolt, etc.;

[0042] Please refer to Figure 1 and Figure 2 In order to further limit the position between the outer shell 40 and the inner shell 30, a limiting recess 41 is set at the edge of the second enclosure 45 and the corresponding position of the first fixed wing 11. After the outer shell 40 and the inner shell 30 are assembled, the first fixed wing 11 is stuck in the limiting recess 41 to ensure that lateral misalignment is not likely to occur between the outer shell 40 and the inner shell 30.

[0043] There are many ways to fix the outer shell 40 and the inner shell 30, as long as they are detachably connected, for example, connected by a second fastener 43, which may be a screw or a bolt; please refer to Figures 1 to 4 The four corners of the second cover plate 44 and the four corners of the first cover plate 33 are detachably connected via second fasteners 43 .

[0044] Alternatively, the outer shell 40 and the inner shell 30 may also be snap-connected, for example, the second cover plate 44 is snap-connected with the first cover plate 33, or the second enclosure 45 is snap-connected with the first enclosure 34, or the above snap-connection forms exist simultaneously.

[0045] In addition, when the second fastener 43 fixes the outer shell 40 and the inner shell 30, there will be a certain gap between the first cover plate 33 and the second cover plate 44. For this reason, a protrusion is formed on the side of the second cover plate 44 facing the first cover plate 33, and a thread for the second fastener 43 to cooperate is formed in the protrusion. The protrusion surrounds the second fastener 43. On the one hand, it can prevent the second fastener 43 from being exposed and rusting. On the other hand, the protrusion on the first cover plate 33 can fix and limit the second fastener 43, that is, a longer threaded hole is provided for the second fastener 43. In addition, a limiting groove corresponding to the above-mentioned protrusion of the first cover plate 33 is formed on the surface of the first cover plate 33 facing the second cover plate 44. When the first cover plate 33 and the second cover plate 44 are pressed and fixed by the second fastener 43, the protrusion on the first cover plate 33 is inserted into the corresponding limiting groove on the second cover plate 44, thereby further positioning the outer shell 40 and the inner shell 30 in the horizontal direction.

[0046] The safety mark 50 may be formed in various forms. For example, the safety mark 50 includes a light-storage type self-luminous material layer, which may be formed of one or more of the following materials: CaAl2O4:Eu, Nb, and Sr4Al 14 O 25 :Eu,Dy; The light-storage self-luminous material layer is relatively fixed to the outer shell 40. Specifically, the light-storage self-luminous material layer can be wrapped in a transparent shell (such as a transparent plastic shell), and then the transparent shell is clamped with the second cover plate 44 of the outer shell 40, wherein the light-storage self-luminous material layer absorbs light energy and stores it when there is light, and uses the stored energy to emit light in a dark state, and can emit light for a long time without an external light source. Alternatively, the light-storage self-luminous material layer can be replaced with a fluorescent material layer, and the external light source can be used to reflect light for safety prompts.

[0047] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
