Description

Technical Field

[0001] This utility model relates to the field of counting equipment technology, and in particular to a counter with hidden mechanical buttons. Background Technology

[0002] Prayer beads, also known as rosaries, are instruments used to assist in counting recitations of Buddhist mantras. Traditionally, counting prayer beads relied on the user memorizing the number of beads moved. However, this method is prone to inaccurate counting due to memory errors, causing some psychological burden on the user. With technological advancements, electronic counters for prayer beads have emerged to overcome the shortcomings of traditional counting methods.

[0003] However, common electronic counters in the prior art typically employ a surface button design, meaning that their function buttons (such as the count button, reset button, etc.) are directly exposed on the surface of the counter's housing, which has the following significant drawbacks:

[0004] 1. High risk of accidental triggering: Since the buttons are directly exposed to the external environment, they are very easy to be accidentally touched during carrying, daily storage or normal use of prayer beads (such as due to friction from clothing, pressure from the hand, contact with other objects, etc.). Such touches can easily cause the counter to accidentally increment or reset, resulting in serious distortion of the counting results, completely deviating from the design purpose of the counter.

[0005] 2. Impact on user experience and structural protection: a. Hygiene and cleaning issues: Sweat, dust and other dirt easily accumulate in the button area (especially the gap between the button and the shell), making it difficult to clean; b. Reduced protective performance: The above-mentioned gaps are more likely to become channels for liquids (such as sweat, rainwater) or solid foreign objects (such as dust, small particles) to enter, seriously weakening the counter's protective capabilities (such as waterproof and dustproof ratings).

[0006] 3. Potential mechanical reliability issues: With prolonged and frequent pressing and accidental impacts, the exposed buttons themselves and the related structures below them are more prone to wear, deformation, or functional failure.

[0007] Therefore, how to provide a counter with hidden mechanical buttons to improve the operational reliability and durability of the counter has become an urgent technical problem to be solved. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to provide a counter with hidden mechanical buttons, thereby improving the operational reliability and durability of the counter.

[0009] This invention is implemented as follows: a counter with hidden mechanical buttons, comprising:

[0010] A lower housing has a crossbeam at the top center, which divides the interior of the lower housing into left and right sides; an upper button mounting base is provided on the upper side of the top of the crossbeam, a lower button mounting base is provided on the lower side, and a support member is provided near the top center;

[0011] An upper housing is located at the top of the lower housing, is detachably connected to the lower housing, and is provided with a display window;

[0012] A PCB board is mounted inside the lower housing using the aforementioned support as a fulcrum;

[0013] A watch movement is mounted on the top of the PCB board with screws and embedded in the display window;

[0014] A display screen is disposed on the surface of the watch movement and connected to the watch movement;

[0015] An upper surface mount button is mounted on the top of the crossbeam via the upper button mounting base, with the top end abutting against the bottom end of the PCB board and connected to the watch core;

[0016] A bottom-mounted button is mounted on the top of the crossbeam via the bottom button mounting bracket, with the top end abutting against the bottom end of the PCB board and connected to the watch core.

[0017] Two batteries are located between the PCB board and the watch core.

[0018] A battery hardware sheet, one end of which is connected to the negative terminal of the two batteries, and the other end of which is connected to the negative terminal of the power supply of the watch core;

[0019] A conductive strip, one end of which is connected to the positive terminals of the two batteries, and the other end of which is connected to the positive terminal of the power supply of the watch core;

[0020] A light guide plate is disposed on the surface of the watch core and covers the display screen;

[0021] A transparent protective plate is provided on the surface of the upper housing, covering the watch movement.

[0022] Furthermore, a finger ring is provided at the bottom end of the lower housing.

[0023] Furthermore, the transparent protective plate has a convex lens structure.

[0024] The advantages of this utility model are:

[0025] 1. A crossbeam is installed at the top center of the lower housing. An upper button mounting base is placed on the upper side of the top of the crossbeam, and a lower button mounting base is placed on the lower side. A support member is placed near the top center. The PCB board is installed inside the lower housing with the support member as a fulcrum. The upper surface-mount button is installed on the top of the crossbeam through the upper button mounting base, and the top of the button abuts against the bottom of the PCB board. The lower surface-mount button is installed on the top of the crossbeam through the lower button mounting base, and the top of the button abuts against the bottom of the PCB board. That is, the PCB board is installed inside the lower housing in a seesaw structure. When the upper part is pressed, it presses against the upper surface-mount button, and when the lower part is pressed, it presses against the lower surface-mount button. The dial core is installed on the top of the PCB board, and a transparent protective plate is placed on the surface of the dial core. That is, by pressing the upper or lower part of the transparent protective plate, the upper or lower surface-mount button can be pressed. The upper and lower surface-mount buttons are hidden inside the lower housing, overcoming the defects of the traditional surface button structure, and thus greatly improving the operational reliability and durability of the counter.

[0026] 2. The upper and lower housings are detachably connected, simplifying the assembly and maintenance process; combined with the transparent protective plate covering the core, a fully enclosed protective system is formed, effectively resisting environmental factors (such as dust, moisture or external impact) from damaging the internal components; the PCB board is installed in the lower housing with the support as the fulcrum, providing a stable installation base, which can buffer vibration or drop impact, and improve the overall structure's shock resistance and durability.

[0027] 3. A light guide plate is placed on the surface of the watch core to cover the display screen. Combined with a transparent protective plate, it provides double protection for display brightness and clarity. The light guide plate can evenly distribute light, making it suitable for low-light environments and improving display readability. The transparent protective plate with a convex lens structure further magnifies the content of the display screen, enhancing the visual effect, especially in applications that require fast reading and counting, reducing misreading errors.

[0028] 4. The battery hardware and conductive strip directly connect the positive and negative terminals of the battery to the power supply of the meter core. The structure is simple and does not require additional wires or soldering points, which reduces the failure rate of poor contact or short circuit and extends battery life.
