Description

Technical Field

[0001] This utility model relates to motion sensors, and more particularly to a snap-on motion sensor. Background Technology

[0002] Currently, Chinese patent CN206867224U discloses a heart rate sensor, including a pressure plate, a pad, a heart rate sensing module, and a housing. The heart rate sensing module is located inside the housing, the pad is located above the heart rate sensing module, and the pad is located below the pressure plate. The housing has a positioning post, and the pressure plate is sleeved on the positioning post. The pressure plate, the pad, the heart rate sensing module, and the housing are tightly fitted together.

[0003] When wearing this type of heart rate sensor, the strap is passed between the pad and the pressure plate and then tied around the user's head, so that the heart rate sensing module fits the head. This results in most of the components of this heart rate sensor being located between the strap and the head, making the area between the strap and the head quite thick. This seriously affects the user's wearing comfort, and because of the thickness, it is unstable and prone to tipping over. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a snap-on motion sensor, which, by placing the power module and the sensor module on opposite sides of the snap-on area, can greatly reduce the thickness when worn through the snap-on area, thereby improving wearing stability and making it less prone to tipping over.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a snap-fit ​​motion sensor, including a housing, a sensor module, and a power module. The housing includes a first mounting part, a second mounting part, and a connecting part. The first mounting part, the connecting part, and the second mounting part are connected in sequence and are internally interconnected. The sensor module is fixed in the first mounting part, and the power module is fixed in the second mounting part and supplies power to the sensor module. A snap-fit ​​area is formed between the first mounting part, the second mounting part, and the connecting part.

[0006] To achieve the above technical solution, the power module is fixed in the second mounting part, the sensor module is fixed in the first mounting part, the lower edge of the hat is embedded in the buckle area, and then the hat is put on the head so that the first mounting part fits the head. Since the first mounting part only contains the sensor module, the thickness of the first mounting part can be made very thin, thereby improving the wearing comfort and making it less likely to tip over and fall off the head.

[0007] In a preferred embodiment of this utility model, the first mounting part includes a first mounting section and a first cover plate, and the second mounting part includes a second mounting section and a second cover plate. The first mounting section is fixedly connected to the second mounting section via a connecting part. The first mounting section has a first opening on its side opposite to the second mounting section. The first cover plate is fixed to the first mounting section and closes the first opening. The second mounting section has a second opening on its side opposite to the first mounting section. The second cover plate is fixed to the second mounting section and closes the second opening. The power module is located between the second mounting section and the second cover plate, and the sensor module is located between the first mounting section and the first cover plate.

[0008] To achieve the above technical solution, the sensor module is fixed in the first mounting section, and then the first cover plate is fixed to the first opening to complete the sensor module installation. The power module is fixed in the second mounting section, and after the power module is connected to the sensor module, the second cover plate is fixed to the second opening to complete the power module installation. This method is convenient for installation and removal.

[0009] In a preferred embodiment of this utility model, the first cover plate has a placement hole for fixing the sensor module on the side facing the first mounting section, and a cover is fixedly connected to the side of the first cover plate facing away from the first mounting section, with the placement hole located inside the cover.

[0010] By implementing the above technical solution, the sensor module is fixed in the placement hole, thereby further reducing the thickness of the first cover plate and improving the sealing performance of the cover.

[0011] In a preferred embodiment of this utility model, the sensor module is fixedly connected to a circuit board, the power module is connected to a ribbon cable, and the end of the ribbon cable away from the power module passes through the connecting part and is connected to the circuit board. The circuit board is located in the first mounting part.

[0012] To achieve the above technical solution, the power module supplies power to the circuit board via a ribbon cable, and the circuit board supplies power to the sensor module, enabling the sensor module to have high measurement accuracy and operational stability.

[0013] As a preferred embodiment of this utility model, the first cover plate is fixedly connected to a plurality of positioning posts on the side facing the first mounting section, and the circuit board is provided with a plurality of positioning holes for cooperating with the positioning posts.

[0014] To achieve the above technical solution, the first cover plate is fixed on the first mounting section, and the positioning pin is inserted into the positioning hole to achieve circuit board positioning. This makes disassembly and assembly convenient, and the circuit board is less likely to move during user movement, thus improving structural stability.

[0015] In a preferred embodiment of this utility model, a wireless charging device is provided in the first mounting part, and the wireless charging device is electrically connected to the circuit board.

[0016] By implementing the above technical solution, the design of this application without external openings can be realized. The power module can be powered by a wireless charging device, which greatly improves protection and makes it less prone to damage.

[0017] As a preferred embodiment of this utility model, the first mounting part has a limiting groove on the side facing the snap-fit ​​area.

[0018] To achieve the above technical solution, after the hat is put on, the buckle area is aligned with the lower edge of the hat, and the buckle area is moved from bottom to top, so that the lower edge of the hat is embedded into the limiting groove, making it less likely for the buckle area to fall off the hat and further improving the connection stability.

[0019] As a preferred embodiment of this utility model, the first mounting part is provided with a limiting protrusion on the side facing the snap-fit ​​area. The limiting protrusion is adjacent to the limiting groove and is located at the end of the snap-fit ​​area away from the connecting part.

[0020] By implementing the above technical solution, the hat has a greater tension at the limiting protrusion and a smaller tension in the limiting groove, making it less likely for the buckle area to fall off the hat.

[0021] As a preferred embodiment of this utility model, an anti-detachment inclined plate is fixed on the limiting protrusion.

[0022] The above technical solution makes it difficult for the hat to detach from the anti-slip plate.

[0023] As a preferred embodiment of this utility model, the limiting protrusion is provided with a guide slope located at the opening of the buckling area, and the guide slope and the limiting groove are respectively located on both sides of the limiting protrusion.

[0024] To achieve the above technical solution, the buckle area is moved from bottom to top, so that the lower edge of the hat is inserted into the buckle area along the guide slope, so that the lower edge of the hat can be inserted into the buckle area. Attached Figure Description

The power module 8 is located between the second mounting section 31 and the second cover plate 32, and the sensor module 11 is located between the first mounting section 21 and the first cover plate 22. The power module 8 refers to a power supply.

[0035] The sensor module 11 includes a heart rate sensor, a blood oxygen sensor, and a six-axis sensor, all of which are fixedly connected to the circuit board 7. A power supply module 8 is connected to a ribbon cable 81, with one end of the ribbon cable 81 passing through the connector 4 and connecting to the circuit board 7, allowing the power supply module 8 to power the sensor module 11. A Bluetooth antenna 103 is located on one side of the ribbon cable 81. An EVA light-shielding frame 105 is fixedly connected to the circuit board 7, ensuring that the end face of the EVA light-shielding frame 105 is pressed against the cover 91 to prevent ambient light from affecting the sensor module 11.

[0036] Foam 106, made of EVA material, is fixedly connected inside the connecting part 4. The foam 106 is closely attached to the Bluetooth antenna 103 to ensure good stability of the Bluetooth antenna 103. Foam 106 is also fixedly connected between the power module 8 and the second cover plate 32.

[0037] A wireless charging device 82 is fixed inside the first mounting part 2, and the wireless charging device 82 is electrically connected to the circuit board 7 via the aforementioned ribbon cable 81.

[0038] Four positioning posts 71 are fixedly connected to the side of the first cover plate 22 facing the first mounting section 21. Four positioning holes 72 are provided on the circuit board 7 for cooperating with the positioning posts 71. One positioning post 71 is inserted into one positioning hole 72 to achieve positioning of the circuit board 7.

[0039] A mounting hole 9 for fixing the sensor module 11 is provided on the side of the first cover plate 22 facing the first mounting section 21, thereby further reducing the thickness of the first cover plate 22. A cover 91 is fixedly connected to the side of the first cover plate 22 facing away from the first mounting section 21, and the mounting hole 9 is located inside the cover 91. Light from the sensor module 11 can pass through the cover 91. The cover 91 is transparent at the position corresponding to the mounting hole 9, and the other positions are not transparent. There are three mounting holes 9.

[0041] A limiting protrusion 101 is provided on the side of the first mounting section 21 facing the snap-fit ​​area 10. The limiting protrusion 101 is adjacent to the limiting groove 100 and is located at the end of the snap-fit ​​area 10 away from the connecting part 4.

[0042] An anti-detachment inclined plate 102 is fixed on the limiting protrusion 101.

[0043] A guide slope 104 is provided on the limiting protrusion 101, and the guide slope 104 and the limiting groove 100 are located on both sides of the limiting protrusion 101.

[0044] Since the power module 8 is located in the second mounting part 3, and the first mounting part 2 only contains the sensor module 11 and the circuit board 7, the thickness of the first mounting part 2 is relatively thin.

[0045] In use, the user wears the hat on their head with the opening of the buckle area 10 facing upwards, aligning the buckle area 10 with the lower edge of the hat. The buckle area 10 is moved from bottom to top, allowing the lower edge of the hat to follow the guide slope 104 and the limiting protrusion 101, subsequently placing it into the limiting groove 100 to achieve a secure connection with the hat, making installation convenient. Because the first mounting part 2 is relatively thin, it feels more comfortable when it fits snugly against the head and is less likely to tip over and fall off the hat.

[0046] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
