Description

Technical Field

[0001] This application relates to the technical field of parachute equipment, and in particular to a parachute altimeter. Background Technology

[0002] Currently, there are two main types of skydiving altimeters on the market: mechanical and electronic.

[0003] Mechanical skydiving altimeters are made entirely of mechanical components, offering advantages such as compact size and no need for battery power. However, they suffer from low measurement accuracy, inconsistent indication, low resolution especially at low altitudes (the range most critical for skydiving), and insufficient intelligence, failing to provide early warning information based on altitude and descent speed.

[0004] Electronic skydiving altimeters are implemented using electronic components. They have the advantage of providing more information through digital displays, but the lack of pointer indicators prevents skydivers from making a summary observation (which is very necessary during the skydive), thus affecting observation efficiency. Utility Model Content

[0005] In order to improve the observation efficiency of skydivers, this application provides a skydiving altimeter.

[0006] This application provides a parachute altimeter, which adopts the following technical solution:

[0007] A skydiving altimeter, comprising:

[0008] Lower housing;

[0009] The upper cover is provided and fixedly installed on the lower housing;

[0010] The dial is fixedly installed inside the lower housing. The dial is divided into a first area, a second area, and a third area. The minimum scale of the first area is 100 meters, and the minimum scale of the second area and the third area is 200 meters.

[0011] A stepper motor, wherein the fixed end of the stepper motor is fixedly mounted on the lower housing;

[0012] A circuit board is fixedly installed inside the lower housing and is electrically connected to the stepper motor. A sensor is fixedly installed inside the lower housing and is electrically connected to the circuit board.

[0013] A rotating wheel, which is coaxially and fixedly mounted on the output end of the stepper motor;

[0014] A pointer is fixedly connected to the rotating wheel, which drives the pointer to rotate. The pointer is positioned above the dial.

[0015] By adopting the above technical solution, when using a parachute altimeter, the circuit board controls the stepper motor and sensor to work. The stepper motor drives a rotating wheel, which in turn causes the pointer to rotate on the dial, thus displaying the altitude. Parachutists can quickly observe their altitude position by identifying the pointer's location in different areas of the dial, improving their observation efficiency.

[0016] Optionally, the bottom of the lower housing is provided with at least one vent hole;

[0017] A vent hood is fixedly installed on the lower housing, and the vent hood is connected to the vent hole.

[0018] A breathable membrane is fixedly installed inside the ventilation hood.

[0019] By adopting the above technical solution, the air pressure inside and outside the parachute altimeter is balanced, while preventing impurities and moisture from entering the lower shell and affecting the accuracy of the parachute altimeter.

[0020] Optionally, a button assembly is fixedly mounted on the lower housing. The button assembly is electrically connected to the circuit board and can control the operation of the circuit board.

[0021] By adopting the above technical solution, the button assembly controls the circuit board, enabling rapid control of the parachute altimeter and improving the ease of operation of the parachute altimeter.

[0022] Optionally, a battery cavity is provided on the lower housing;

[0023] A power supply battery is fixedly installed inside the battery cavity, and the power supply battery is electrically connected to the circuit board.

[0024] A battery compartment cover is detachably installed on the lower housing, and the battery compartment cover is disposed on the battery cavity.

[0025] By adopting the above technical solution, it is convenient to quickly replace the battery inside the skydiving altimeter, thereby improving the ease of use of the skydiving altimeter.

[0026] Optionally, the first area can be painted with two different colors.

[0027] By adopting the above technical solution, skydivers can quickly observe their altitude position by identifying the different colored areas where the pointer is located in the first area, thus improving the skydiver's observation efficiency.

[0028] Optionally, the colors of the second region and the third region are both different from the color of the first region.

[0029] By adopting the above technical solution, skydivers can quickly observe their altitude position by identifying the different colored areas where the pointer is located on the dial, thus improving their observation efficiency.

[0030] Optionally, an indicator light is fixedly installed on the dial, and the indicator light is electrically connected to the circuit board.

[0031] By adopting the above technical solution, when the circuit board is working normally, the circuit board control indicator light is green; when the parachute altimeter malfunctions or the battery is low, the circuit board control indicator light is red; when the parachutist enters the warning area and still does not open the parachute, the circuit board control indicator light flashes red and blue, which makes it convenient for the parachutist to quickly check the status of the parachute altimeter and improves the parachutist's observation efficiency.

[0032] Optionally, a light strip is fixedly installed inside the upper cover, and the light strip is electrically connected to the circuit board.

[0033] By adopting the above technical solution, the circuit board controls the light strip. When the visibility is low, the circuit board controls the light strip to turn on, and the light strip illuminates the dial, making it easier for the skydiver to see and improving the skydiver's observation efficiency.

[0034] In summary, this application includes at least one of the following beneficial technical effects:

[0035] 1. When using a skydiving altimeter, the circuit board controls a stepper motor and a sensor. The stepper motor drives a rotating wheel, which in turn moves a pointer on the dial, allowing the altitude to be read. Skydivers can quickly observe their altitude by identifying the pointer's position in different areas of the dial, improving their observation efficiency.

[0036] 2. The ventilation hood ensures the air pressure inside and outside the parachute altimeter is balanced, while preventing impurities and moisture from entering the lower housing and affecting the accuracy of the parachute altimeter.

[0037] 3. By identifying the different colored areas on the dial where the pointer is located, skydivers can quickly observe their altitude position, thus improving their observation efficiency. Attached Figure Description
