Description

Technical Field

[0001] This utility model relates to the field of toy technology, and in particular to a toy for counting laps. Background Technology

[0002] As children, we often played the game of spinning a coin or other smooth object on a table. With the naked eye, we could only compare the length of time it took to spin, but we couldn't accurately record the exact number of spins. In fact, a longer spinning time does not necessarily mean more spins, making the game rather monotonous. Utility Model Content

[0003] The purpose of this invention is to provide a toy for counting loops, thereby solving the technical problems existing in the prior art. The preferred technical solutions among the various technical solutions provided by this invention and their numerous technical effects are detailed below.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A toy for counting laps includes a housing and an LCD unit, a PCB board, and two photosensitive sensors located inside the housing. The LCD unit is electrically connected to the PCB board, and the two photosensitive sensors are electrically connected to the PCB board and symmetrically distributed. The LCD unit has a light guide at a corresponding position of each photosensitive sensor. The housing has an LCD display window at a corresponding position of the LCD unit and a light collection window at a corresponding position of each photosensitive sensor. Each light collection window, the corresponding light guide, and the corresponding photosensitive sensor are arranged sequentially and on the same straight line.

[0006] Preferably, the housing includes an upper housing and a lower housing, the upper housing and the lower housing are detachably connected and can clamp the PCB board between them, and the upper housing has the LCD display window and the light acquisition window.

[0007] Preferably, the LCD unit includes an LCD mounting bracket and an LCD body. The LCD mounting bracket is sandwiched between the upper housing and the PCB board. The light guide is disposed on the LCD mounting bracket. The LCD body is connected to the LCD mounting bracket. The LCD body corresponds to the LCD display window and is electrically connected to the PCB board.

[0008] Preferably, the light guide is a groove-shaped opening, one end of the light guide is connected to the light acquisition window, and the other end of the light guide is covered outside the photosensitive sensor.

[0009] Preferably, the opening size of the light guide gradually increases from the end near the light acquisition window to the end near the photosensitive sensor.

[0010] Preferably, the LCD mounting bracket is provided with a positioning post, and the PCB board is provided with a positioning hole, the positioning post and the positioning hole form a positioning.

[0012] Preferably, the device further includes a battery located inside the housing and electrically connected to the PCB board.

[0013] The beneficial effects of this utility model are as follows: light can pass through the light collection window and the light guide in sequence and then illuminate the photosensitive sensor. The photosensitive sensor can monitor the changes in light. When the product is in a static state, since the two photosensitive sensors are on the same surface, there will be no change in state regardless of whether the specific position of the light collection window is upward or downward, or whether the light from the two light collection windows is consistent.

[0014] When the product is thrown into the air or spun on a table, the two light-collecting windows sometimes move upwards and sometimes downwards, or sometimes to the left and sometimes to the right due to the rotation. The light collected changes with each rotation. The photosensor can monitor the changes in light and then transmit the detected signal to the PCB board. The PCB board can record the number of rotations and then transmit the signal to the LCD unit for digital display, thereby realizing the automatic calculation of the number of rotations. The overall structure of the rotation counting toy is simpler, easier to use, and more fun. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be understood that the terms "center," "side," "length," "width," "height," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and "side," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The orientations or positional relationships shown are for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Reference Figures 1 to 4This utility model provides a toy for counting laps, including a shell 1 and an LCD unit 2, a PCB board 3, and a photosensitive sensor 4 located inside the shell 1. The shell 1 provides support and protection for the LCD unit 2, the PCB board 3, and the photosensitive sensor 4. The LCD unit 2 is electrically connected to the PCB board 3, and the two photosensitive sensors 4 are electrically connected to the PCB board 3 and are symmetrically distributed. The LCD unit 2 is provided with a light guide 211 at the corresponding position of each photosensitive sensor 4. The shell 1 has an LCD display window 111 at the corresponding position of the LCD unit 2 and a light collection window 112 at the corresponding position of each photosensitive sensor 4. Each light collection window 112, the corresponding light guide 211, and the corresponding photosensitive sensor 4 are arranged sequentially and on the same straight line.

[0030] Light can pass through the light collection window 112 and the light guide 211 in sequence and then illuminate the photosensitive sensor 4. The photosensitive sensor 4 can monitor the changes in light. When the product is stationary, since the two photosensitive sensors 4 are on the same surface, there will be no change in state regardless of whether the specific position of the light collection window 112 is up or down, or whether the light from the two light collection windows 112 is consistent.

[0031] When the product is thrown into the air or spun on a table, the two light-collecting windows 112 sometimes move upwards, sometimes downwards, sometimes to the left, and sometimes to the right due to the rotation. The light collected changes with each rotation. The photosensitive sensor 4 can monitor the changes in light and then transmit the detected signal to the PCB board 3. The PCB board 3 can record the number of rotations and then transmit the signal to the LCD unit 2 for digital display, thereby realizing the automatic calculation of the number of rotations. The overall structure of the rotation counting toy is simpler, easier to use, and more fun.

[0032] As an optional implementation, the housing 1 includes an upper housing 11 and a lower housing 12, which are detachably connected. Preferably, the connection is between a connecting post and a connecting hole.

[0033] When the upper housing 11 and the lower housing 12 are connected, the PCB board 3 can be clamped between the two at the same time, thereby fixing the PCB board 3. The structural design makes reasonable use of the structure and makes the connection of the PCB board 3 simpler.

[0034] The upper housing 11 is provided with an LCD display window 111 and a light acquisition window 112.

[0035] As an optional implementation, the LCD unit 2 includes an LCD fixing bracket 21 and an LCD body 22. The LCD fixing bracket 21 is sandwiched between the upper housing 11 and the PCB board 3. This arrangement makes reasonable use of the structural design and simplifies the connection of the LCD fixing bracket 21.

[0036] The light guide 211 is mounted on the LCD mounting bracket 21, and the LCD body 22 is connected to the LCD mounting bracket 21. The LCD body 22 corresponds to the LCD display window 111. The LCD body 22 is electrically connected to the PCB board 3, and the LCD body 22 can display the numbers recorded on the PCB board 3 in real time.

[0037] As an optional implementation, the light guide 211 is a groove-shaped opening, one end of the light guide 211 is connected to the light collection window 112, and the other end of the light guide 211 is covered outside the photosensitive sensor 4.

[0038] In this embodiment, the opening size of the light guide 211 gradually increases from the end near the light acquisition window 112 to the end near the photosensitive sensor 4. This setting can improve the light acquisition effect and further improve the accuracy.

[0039] As an optional implementation, the LCD mounting bracket 21 is provided with a positioning post 212 and the PCB board 3 is provided with a positioning hole 31. The positioning post 212 and the positioning hole 31 form a positioning, thereby further improving the connection effect between the LCD mounting bracket 21 and the PCB board 3 inside the housing 1 and optimizing the structural layout.

[0040] In this embodiment, the number of positioning posts 212 and positioning holes 31 is preferably two, and the two positioning posts 212 are symmetrically distributed, and the two positioning holes 31 are also symmetrically distributed.

[0041] As an optional implementation, a transparent cover 5 is also included. The transparent cover 5 is sandwiched between the upper housing 11 and the LCD fixing bracket 21. The transparent cover 5 is located at the LCD display window 111. The transparent cover 5 can protect the LCD body 22 without affecting the display effect of the LCD body 22.

[0042] As an optional implementation, a battery 6 is also included. The battery 6 is located inside the housing 1 and is electrically connected to the PCB board 3. The battery 6 can provide power to the lap counting toy.

[0043] In this embodiment, the battery 6 can be replaced by disconnecting the upper housing 11 from the lower housing 12, or a rechargeable battery can be used and charged through a charging connector.

[0044] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
