Description

Technical Field

[0001] The utility model relates to the technical field of amusement equipment, in particular to a trampoline depression depth detection device. Background Art

[0002] In amusement equipment that scores points by jumping on a trampoline, the specific gameplay is that when the player jumps on the center of the trampoline and causes the trampoline to sink to a set depth, the player will gain a point; if the player's fall is not deep enough to cause the trampoline to sink to the set depth, the player will not gain any points. To achieve this gameplay, the trampoline usually needs to be equipped with a detection device that can determine the degree of deformation of the trampoline of the amusement machine.

[0003] The existing trampoline detection device is to install a light sensor and a light at a reasonable position under the trampoline, and align the light irradiation position with the light eye of the light sensor. At the same time, a light blocking plate is installed behind the trampoline treading surface. Whenever the trampoline sinks to a set depth, the light blocking plate just reaches the light blocking position and can block the light irradiating the light eye of the light sensor. At this time, the light sensor will send a signal to the scorer, and the scorer will record the player's score.

[0004] However, since the trampoline will generate strong vibrations during use, the light shield is easily shaken off, and the installation position of the photosensor is also easily offset. In this process, dust will continue to fall onto the surface of the photoeye. Excessive accumulation of dust on the surface of the photoeye can easily lead to scoring errors, resulting in a high failure rate of the detection device and the need for frequent maintenance of the amusement equipment.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0024] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limiting this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limiting this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0026] In the description of this utility model, unless otherwise expressly specified or limited, when the term "connection" or the like appears to indicate a connection relationship between components, such term should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be internal communication between two components or an interaction relationship between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0027] like Figure 1 As shown, the utility model provides a trampoline depression depth detection device, including a placement bracket 1, one end of the placement bracket 1 is installed with a roller assembly 2 and a spring assembly 3, and the other end is installed with a pull rope 4, the other end of the pull rope 4 is sleeved on the roller assembly 2 and connected to the spring assembly 3, and the placement bracket 1 is also installed with an angle sensor 5, the angle sensor 5 is connected to the roller assembly 2, and the angle sensor 5 is electrically connected to an external controller, and the external controller is used to determine whether the player has scored; the pull rope 4 of the utility model is preferably a nylon rope. By placing the pull rope 4 under the trampoline, when the player jumps on the trampoline and drives the trampoline to sink, the jumping surface of the trampoline The back will press down on the pull rope 4. At this time, the spring component 3 at one end of the pull rope 4 will undergo elastic deformation under the tension of the pull rope 4. At the same time, the roller component 2 will also rotate under the friction of the pull rope 4, and the angle sensor 5 will send the angle change information of the roller component 2 to the external controller. The external controller can determine whether the player has scored according to whether the size of the angle change reaches the set value. The present invention abandons the structural design of the light baffle and the photosensor, and instead adopts the contact method of the trampoline and the pull rope 4, avoiding injuries caused by the direct contact of the limbs of the player with the light baffle and other components after the player steps on the trampoline and collapses the trampoline in extreme cases.

[0028] like Figure 2 and Figure 3As shown, the placement bracket 1 of the present invention specifically includes a base plate 11, and a front bracket 12 and a rear bracket 13 are respectively installed at both ends of the base plate 11, a first tether shaft 131 is installed on the rear bracket 13, and a first retaining spring 132 is installed at both ends of the first tether shaft 131, and one end of the pull rope 4 is connected to the first tether shaft 131; the front bracket 12 specifically includes two side brackets 121 installed on the left and right sides of one end of the base plate 11, the roller assembly 2 is installed between the two side brackets 121, and a second tether shaft 122 is also installed between the two side brackets 121, and a second retaining spring 123 is installed at both ends of the second tether shaft 122. One end of the component 3 is connected to the second tether shaft 122, and the other end is connected to the pull rope 4 sleeved on the roller component 2. The pull rope 4 installed on the placement bracket 1 can be adjusted by the spring component 3 to keep the pull rope 4 in a taut state. At the same time, the center of the pull rope 4 is aligned with the center of the trampoline. When the player jumps in the center of the trampoline, the back center of the trampoline can effectively contact the pull rope 4; at the same time, in order to increase the contact area between the pull rope 4 and the roller component 2, the pull rope 4 can be wrapped around the roller component 2 once and then connected to the spring component 3. When the pull rope 4 is under pressure, the roller component 2 is subjected to greater friction, thereby more effectively driving the roller component 2 to rotate.

[0029] like Figure 4 As shown, the roller assembly 2 specifically includes a roller 21, a wheel hub 22 is installed on the roller 21, and a transmission shaft 23 is installed on the wheel hub 22. Specifically, the screw hole of the wheel hub 22 can be aligned with the plane in the middle of the transmission shaft 23, and a headless screw is passed through the screw hole of the wheel hub 22 to abut the plane in the middle of the transmission shaft 23, so that the wheel hub 22 is fixed on the transmission shaft 23, and third retaining springs 24 are installed at both ends of the transmission shaft 23, and bearings 25 are installed on the two side brackets 121, and the two ends of the transmission shaft 23 are respectively connected to the bearings 25 of the two side brackets 121; one of the side brackets 121 is also equipped with a mounting bracket 6, and the angle sensor 5 is installed on the mounting bracket 6, and the angle sensor 5 is connected to the transmission shaft 23 through a coupling 7. When the roller 21 rotates, the rotating rod of the angle sensor 5 will also rotate accordingly, thereby recording the rotation angle of the roller 21. The angle sensor 5 of the utility model is not affected by dust attached to the surface and can achieve the effect of accurate scoring.

[0030] The spring assembly 3 specifically includes a spring 31 connected to the second tether shaft 122, the other end of the spring 31 is connected to a connecting block 32, and the other end of the connecting block 32 is connected to the pull rope 4 sleeved on the roller assembly 2. When the trampoline sinks, the pull rope 4 will be subjected to the pressure of the trampoline, and the spring 31 will be elastically deformed by the tension of the pull rope 4. When the trampoline rises, the pressure on the pull rope 4 disappears, and the spring 31 will pull the pull rope 4 to quickly restore to its original state, thereby waiting for the next judgment of the degree of sinking of the trampoline; the spring 31 of the utility model has a unique vibration reduction effect, can work for a long time in various vibration environments, has strong anti-interference ability, and has a stable use effect.

[0031] The overall working principle of this utility model:

[0032] Before using the trampoline pressure depth detection device of the present invention, the placement bracket 1 is first fixedly installed under the trampoline so that the pull rope 4 maintains a certain distance from the back of the trampoline jumping surface. Under the tension of the spring 31, the pull rope 4 is kept taut, so that the pull rope 4 remains parallel to the trampoline jumping surface and the center of the pull rope 4 is on the same vertical line as the center of the trampoline jumping surface, forming an initial state.

[0033] When the player is playing on the trampoline, the trampoline sinks, which will cause the back of the jumping surface to press against the pull rope 4. The spring 31 at one end of the pull rope 4 will undergo elastic deformation under the tension of the pull rope 4. At the same time, the roller 21 will also rotate under the friction of the pull rope 4. Since the transmission shaft 23 of the roller assembly 2 is connected to the rotating rod of the angle sensor 5, the angle sensor 5 will rotate synchronously with the roller 21. At this time, the angle sensor 5 will send the measured angle change information to the external controller. The external controller can determine whether to give the player extra points based on whether the angle change reaches a set value. When the trampoline sinks deep enough, the angle change measured by the angle sensor 5 reaches the set value, and the external controller will give the player an extra point. When the trampoline sinks less, the angle change measured by the angle sensor 5 does not reach the set value, and the player cannot score.

[0034] When the trampoline turns from the sunken state to the raised state under the action of its own elastic force, the pressure on the pull rope 4 disappears, and the spring 31 connected to the pull rope 4 will shrink and recover, thereby pulling the pull rope 4 to quickly return to the initial state, waiting for the next judgment of the trampoline's sinking degree.

[0035] It should be noted that the above-described specific embodiments are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that various modifications, equivalent substitutions, and variations may be made to the present invention. However, as long as these modifications do not depart from the spirit of the present invention, they are within the scope of protection of the present invention. Furthermore, certain terms used in the specification and claims of this application are not intended to be limiting but are provided for ease of description only.
