Description

Technical Field

[0001] The utility model relates to the technical field of pedometers, in particular to a structure for preventing high-frequency vibration from damaging the components of a pedometer. Background Technique

[0002] A pedometer is a measuring tool that calculates data such as the number of steps, distance, speed, and time, and measures calorie or heat consumption to control the amount of exercise and prevent insufficient or excessive exercise. A pedometer mainly consists of a vibration sensor and an electronic counter. When a person walks, the center of gravity will move up and down to some extent, and the up and down displacement of the waist is the most obvious. Therefore, it is most suitable to hang the pedometer on the waistband.

[0003] Based on the above, in the production process of existing pedometers, the front cover and the rear cover of the pedometer are usually welded together by an ultrasonic welding device, which not only has the function of connecting and assembling, but also has a moisture-proof and waterproof sealing effect. However, during the ultrasonic welding process, since ultrasonic welding will generate high-frequency vibrations, it is relatively easy to damage or damage the electronic components inside the pedometer.

[0006] 2. Technical Solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A structure for preventing high-frequency vibration from damaging the components of a pedometer, the structure includes a rear cover, a front cover, a silicone button, a liquid crystal display screen and a safety pin buckle.

The front cover is provided with a silicone button and a liquid crystal display screen, and the other side of the rear cover is provided with a safety pin buckle.

[0009] As an optimization, a PCB board and a buffer pad are installed inside the front cover. The PCB board is the movement of the pedometer and is electrically connected to the liquid crystal display screen.

[0010] As an optimization, the buffer pad is located at the bottom of the front cover, and the other side of the buffer pad is in contact with the liquid crystal display screen.

[0014] 3. Beneficial effects

[0015] Compared with the prior art, the advantages of the utility model are:

[0016] (1) The utility model discloses a structure for preventing high-frequency vibration from damaging pedometer components. A buffer pad is provided on the front cover. Under the action of the buffer pad and the silicone button, a PCB board and a liquid crystal display screen will not have direct contact with the front cover. During the ultrasonic welding process of the front and rear covers of the pedometer (i.e., in a high-frequency vibration environment), the front cover has a certain elasticity through the buffer pad and the silicone button, so that the collision and impact between the electronic components and the housing can be greatly reduced, thereby reducing the damage to the electronic components.

[0017] (2) The utility model provides a structure for preventing high-frequency vibration from damaging pedometer components. By utilizing the limiting effect between the concave stopper of the front cover and the convex stopper of the rear cover, an avoidance structure is provided for the inner space of the rear cover (i.e., the inner space of the rear cover and the area where the PCB may contact are subjected to corresponding glue reduction treatment). This allows a larger space gap to be created between the PCB and the rear cover, and prevents direct collision between the PCB and the rear cover due to high-frequency vibration generated during ultrasonic welding.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment:

[0027] Please refer to Figures 1-6 , a structure for preventing damage to the components of a pedometer caused by high - frequency vibration, the structure includes a rear cover 1, a front cover 2, a silicone button 3, a liquid crystal display screen 4 and a safety pin buckle 5. The front cover 2 is ultrasonically welded to the rear cover 1. The silicone button 3 and the liquid crystal display screen 4 are installed on the front cover 2. On the other side of the rear cover 1, a safety pin buckle 5 for wearing the pedometer is installed.

[0028] In this embodiment, a PCB board 6 and a buffer pad 7 are installed inside the front cover 2. The PCB board 6 is the movement of the pedometer and is electrically connected to the liquid crystal display screen 4, and can carry the connection lines between the internal electronic components of the pedometer, making the transmission of current more stable and efficient.

[0029] In this embodiment, the buffer pad 7 is located at the bottom of the front cover 2, and the other side of the buffer pad 7 is in contact with the liquid crystal display screen 4, which can buffer the contact between the front cover 2 and the liquid crystal display screen 4.

[0030] In this embodiment, a contact core 61 is installed on the top of the PCB board 6. The contact core 61 is in contact with the silicone button 3, and can drive the PCB board 6 to operate by the contact between the silicone button 3 and the contact core 61 when pressed. There is an avoidance structure in the internal space of the rear cover 1. Under the limiting effect between the concave stop of the front cover and the convex stop of the rear cover, there is a large space gap between the PCB board 6 and the rear cover 1, and the PCB board 6 will not be damaged due to the vibration of the rear cover 1 during ultrasonic welding.

[0031] In this embodiment, an installation groove 11 is provided on the rear cover 1, and a buckle 12 is fixed on the installation groove 11.

[0032] In this embodiment, an engaging groove 51 is installed on the safety pin buckle 5, and the engaging groove 51 can be movably engaged with the buckle 12 on the rear cover 1 to install the safety pin buckle 5 on the rear cover 1.

[0033] Working principle: During the production process of the pedometer, when the front cover 2 and the back cover 1 of the pedometer are ultrasonically welded, an avoidance structure is made for the internal space of the back cover 1 by utilizing the limiting effect between the concave stopper of the front cover and the convex stopper of the back cover (that is, the internal space of the back cover 1 and the possible contact area with the PCB board 6 are subjected to corresponding glue reduction treatment), so that there is a larger space gap between the PCB board 6 and the back cover 1, and then a buffer pad 7 is installed between the front cover 2 and the PCB board 6 and the liquid crystal display screen 4, and the buffer pad 7 is in contact with the liquid crystal display screen 4, so that there is no direct contact between the front cover 2 and the liquid crystal display screen 4, and effective buffering can be performed when subjected to external force. When the front cover 2 and the back cover 1 are ultrasonically welded, the high-frequency vibration generated in the process will not damage the PCB board 6, thereby effectively protecting electronic components such as the PCB board 6.
