Description

TECHNICAL FIELD

[0001] The present invention relates to a fastener device, and more particularly to a fastener device capable of displaying a locking state. BACKGROUND

[0002] Ride facilities providing a body sensation effect cause a seat to move or rotate to generate a body sensation effect. To avoid danger to a rider, a safety belt is provided on the seat, and a locking structure having a clasp and a fastener is used to fix the rider to the seat to avoid danger to the rider when the ride facility is in operation, and the rider can be close to the seat to feel the body sensation effect generated when the seat moves.

[0003] Reference Figure 1 Taiwanese Patent I684541 discloses a fastener device 10 capable of providing a clasp 11 to be inserted. The fastener device 10 includes two vertical turntables 101, a button 102, two electromagnetic push rods 103, two first springs 104 provided between the two vertical turntables 101 and the button 102, two second springs 105 provided on the two electromagnetic push rods 103, respectively, and two detectors 106 used to detect the two electromagnetic push rods 103.

[0004] The vertical turntable 101 can interfere with the clasp 11 to lock the clasp 11 in the fastener device 10. After the button 102 is pressed by an external force, the locking state of the vertical turntable 101 is released, so that the first spring 104 pushes the vertical turntable 101, and the clasp 11 is pushed outwards.

[0005] The second spring 105 is used to push the electromagnetic push rod 103 into the vertical turntable 101 to lock the vertical turntable 101, so that the vertical turntable 101 cannot be rotated even if the button 102 is pressed. After the electromagnetic push rod 103 is separated from the vertical turntable 101, the button 102 can release the locking state of the vertical turntable 101 on the clasp 11.

[0006] Although the prior art discloses a fastener device, the following disadvantages still exist in actual use:

[0007] I. Not easy to use in a dim place:

[0008] Many devices providing a dynamic function provide a dynamic animation, and the indoor space is usually dim to clearly present the animation. However, the dim environment makes it difficult for a passenger on a ride seat to find the clasp position, and the clasp cannot be easily set or released.

[0009] II. Cannot know the locking state from the appearance:

[0010] When the passenger is seated on the seat of the motion device, and the control device activates the electromagnetic lock, the staff confirms the locking state of the buckle one by one at the seat position. Since the staff must press the button and then confirm that the buckle is not ejected outward, the locking of the buckle is completed. Therefore, the staff cannot directly judge the locking state from the appearance of the buckle.

[0011] III. Difficulty in maintaining safe social distance:

[0012] As described above, the staff must be very close to the passenger to confirm whether the buckle is locked by pressing the buckle. This will cause the staff to come into contact with many passengers, making it difficult to maintain safe social distance and easily spreading viruses or bacteria.

[0013] IV. Complex structure:

[0014] The existing vertical turntable has a complex structure with multiple grooves and protrusions to correspond to the spring or locking structure. It cannot be assembled in a progressive manner. The assembler must overcome the spring force and the unstable structure position of the rotating structure due to rotation to set the parts in the buckle device. The structure is complex and difficult to assemble.

[0015] V. Unable to block the button from being pressed:

[0016] After the existing electromagnetic push rod and vertical turntable interfere, the button can still be pressed by external force. Although the vertical turntable cannot be rotated due to interference by the electromagnetic push rod, the button can be pressed, which will cause the rider to feel more uneasy.

[0017] Therefore, how to quickly confirm the position of the buckle in a dim environment and provide staff with the ability to confirm the locking state of the buckle from its appearance to further avoid close contact with passengers to prevent the spread of germs is the goal of related technical personnel.

[0061] In the first preferred embodiment, the fastener device is further provided with a connection with an extension fixing body 203, the extension fixing body 203 is provided with a plurality of fixing holes 204 and a plurality of locking holes 205, two locking assemblies 206 pass through the two locking holes 205 to lock the fastener device and the extension fixing body 203 together, the fixing hole 204 can fix the extension fixing body 203 on a seat (not shown in the figure), so that the fastener device is arranged on the seat, in addition, a belt (not shown in the figure) can be further matched to fix a passenger (not shown in the figure) on the seat, the seat is arranged on an amusement facility, the amusement facility moves the position of the seat, the belt and the fastener device are combined into a safety belt to protect the safety of the passenger riding the seat, since the seat with safety belt arranged on the amusement facility is prior art, which will not be described in detail here.

[0062] The main unit 3 comprises a main body 32 surrounding a containing space 31, at least a first through hole 33 arranged on the main body 32, two sliders 34 arranged in the containing space 31, two slider elastic bodies 35 abutting together with the sliders 34, two second through holes 36 arranged on the main body 32 and spaced apart from the first through hole 33, two plate through holes (not shown in the figure) arranged on the main body 32 and two sliding guide bodies 38 arranged on the two sliders 34 (see Figure 16 ).

[0063] The main body 32 has a first plate 321, a second plate 322 spaced apart from the first plate 321, two third plates 323 spaced apart and connected with the first plate 321 and the second plate 322, a fourth plate 324 connected with the two third plates 323 and spaced apart from the first plate 321, two electromagnetic fixing parts 325 arranged on the first plate 321 and a plurality of stop parts 326 arranged on the fourth plate 324, the first plate 321, the second plate 322 and the two third plates 323 cooperatively surround the containing space 31, the two first through holes 33 are arranged on the first plate 321, and the two second through holes 36 are arranged on the second plate 322.

[0064] The two third plate portions 323 are vertically erected on the two side edges of the second plate portion 322, and are arranged in the two plate hole portions of the first plate portion 321. The fourth plate portion 324 is arranged on the top of the two third plate portions 323 and is connected to each other. The first plate portion 321 and the fourth plate portion 324 are spaced apart from each other. The two electromagnetic fixing portions 325 are connected to the fourth plate portion 324. The upper surfaces of the two sliders 34 are defined as two first surfaces 39, and the two first surfaces 39 face the first plate portion 321.

[0065] The extension fixing body 203 is clamped between the first plate portion 321 and the second plate portion 322. The two locking assemblies 206 lock the first plate portion 321, the extension fixing body 203 and the second plate portion 322 together. The distance between the first plate portion 321 and the second plate portion 322 is the height of the accommodating space 31. The thickness of the two sliders 34 is matched with the height of the accommodating space 31, so that the two sliders 34 can slide horizontally in the accommodating space 31. The two sliding guide bodies 38 are two protrusions arranged on the bottom surfaces of the two sliders 34. The second plate portion 322 is provided with two blocking portions 327 (see Figure 16 ). The two blocking portions 327 abut against the two sliding guide bodies 38, thereby limiting the slidable position of the two sliders 34 in the accommodating space 31.

[0066] The buckle unit 4 includes a buckle piece 41 which is arranged in the accommodating space 31 and is detachably abutted against the slider 34. The buckle unit 4 also includes two buckle holes 42 arranged on the buckle piece 41 and a second surface 43 arranged on the buckle piece 41. When the buckle piece 41 enters the accommodating space 31, the second surface 43 faces the first plate portion 321.

[0067] The thickness of the buckle piece 41 is matched with the height of the accommodating space 31, so that when the buckle piece 41 enters the accommodating space 31, the two first surfaces 39 are consistent with the height of the second surface 43. The buckle piece 41 can slide in the accommodating space 31. The left side of the accommodating space 31 is communicated with the external space, so that the buckle piece 41 can be inserted into the accommodating space 31 from the external space. The buckle piece 41 can also be removed from the accommodating space 31.

[0068] For reference, Figure 9 and Figure 10, in the first preferred embodiment, the vertical length of the two slider elastic bodies 35 is greater than the vertical length of the accommodating space 31, so the first plate portion 321 and the second plate portion 322 are respectively provided with two openings for fixing the two slider elastic bodies 35. The shape of the plurality of openings is approximately rectangular, the length of the plurality of openings is equal to the length of the two slider elastic bodies 35, and the width of the plurality of openings is less than the width of the two slider elastic bodies 35, so that the first plate portion 321 and the second plate portion 322 on the side of the plurality of openings can fix the upper and lower sides of the two slider elastic bodies 35. The first plate portion 321 and the second plate portion 322 on the right side of the plurality of openings can support the right side of the two slider elastic bodies 35, and the left side of the two slider elastic bodies 35 is in contact with the right side of the two sliders 34, so that the elastic force of the two slider elastic bodies 35 can push the two sliders 34 to slide to the left in the accommodating space 31, or the two sliders 34 can slide to the right in the accommodating space 31 under the action of external force and compress the two slider elastic bodies 35. In actual implementation, the two slider elastic bodies 35 can be fixed by other structures, which should not be limited by this.

[0069] The lock unit 5 includes two plug bodies 51 passing through the first perforation 33, two lock elastic bodies 52 in contact with the plug bodies 51, and two lock guide bodies 53 connected with the plug bodies 51. The two lock guide bodies 53 respectively have two side walls 531 connected with the first plate portion 321, two guide portions 532 respectively provided on the two side walls 531, and a top wall 533 connected with the two side walls 531. Each plug body 51 has a locking portion 511 provided in the first perforation 33 and capable of extending into the accommodating space 31 and the second perforation 36, a protruding portion 512 connected with the locking portion 511 and provided between the two side walls 531, and two side wings 513 connected with the protruding portion 512 and respectively passing through the two guide portions 532.

[0070] In the first preferred embodiment, the fourth plate portion 324 and the two lock guide bodies 53 are of an integral structure, which can be separated into individual structures in actual implementation. The protruding portion 512 can provide a space for the lock elastic body 52, the front and rear sides of the two side walls 531 are connected with each other and define a space for stabilizing the lock elastic body 52, so as to avoid the lock elastic body 52 from being in contact with other spring structures. The top end of the lock elastic body 52 supports the fourth plate portion 324, and the bottom end of the lock elastic body 52 is sleeved on the protruding portion 512, so that the lock elastic body 52 can push the plug body 51 downward.

[0071] When the two sliders 34 are separated from the buckle 41, the two sliders 34 are pushed by the two slider elastic bodies 35, so that the positions of the two sliders 34 are respectively below the two first through holes 33, and the first surfaces 39 on the two sliders 34 abut against the bottom ends of the locking portions 511 of the two bolt bodies 51, so as to block the locking portions 511 of the two bolt bodies 51 from entering the accommodating space 31.

[0072] When the buckle 41 contacts the two sliders 34, the buckle 41 can be pushed by an external force and move the two sliders 34, so that the two sliders 34 are away from below the two first through holes 33. At this time, the two locking elastic bodies 52 push the locking portions 511 of the two bolt bodies 51 into the accommodating space 31, the locking portions 511 of the two bolt bodies 51 pass through the two buckle holes 42 of the buckle 41, at this time, the two bolt bodies 51 interfere with the buckle 41, so as to block the buckle 41 from leaving the accommodating space 31.

[0073] Since the extension fixing body 203 is clamped between the first plate portion 321 and the second plate portion 322, the interval distance between the first plate portion 321 and the second plate portion 322 is defined by the thickness of the extension fixing body 203, so that the thickness of the accommodating space 31 is the same as the thickness of the extension fixing body 203, and the thicknesses of the buckle 41 and the two sliders 34 are matched with the interval distance between the first plate portion 321 and the second plate portion 322, so that the buckle 41 and the two sliders 34 can stably slide in the horizontal direction in the accommodating space 31. For example, the thicknesses of the buckle 41 and the two sliders 34 are equal, and the thicknesses of the buckle and the sliders are less than the interval distance between the first plate portion 321 and the second plate portion 322 by 0.01 centimeters, and the bottom surface of the first plate portion 321 and the top surface of the second plate portion 322 can clamp the buckle 41 and the two sliders 34. In actual implementation, the interval distance between the first plate portion 321 and the second plate portion 322, or the thicknesses of the buckle 41 and the two sliders 34, should be set according to actual mechanical structure, and should not be limited by this.

[0074] As described above, the first plate portion 321 and the second plate portion 322 can clamp the two sliders 34, so that the two sliders 34 can stably slide in the accommodating space 31, and when the buckle 41 enters the accommodating space 31, the first plate portion 321 and the second plate portion 322 can clamp the buckle 41, so that the buckle 41 can stably slide in the accommodating space 31.

[0075] When the buckle 41 and the two sliders 34 abut against each other in the accommodating space 31 and slide, the buckle 41 and the two sliders 34 can in turn abut against the two bolt bodies 51. The two bolt bodies 51 can only enter the accommodating space 31 and extend into the two second through holes 36 in the condition of extending into the two buckle holes 42, and in other conditions, the two bolt bodies 51 are abutted against by the buckle 41 or the two sliders 34 and cannot enter the accommodating space 31.

[0076] For example, when the clasp 41 enters the accommodation space 31 and abuts against the two sliders 34 and is pushed by external force, the clasp 41 pushes the two sliders 34 away from below the two first perforations 33, and the clasp 41 moves to below the two first perforations 33. When the clasp 41 and the two sliders 34 slide in the accommodation space 31, the two pegs 51 slide on the first surfaces 39 of the two sliders 34 and slide to the second surface 43 of the clasp 41, so that the clasp 41 supports the two pegs 51 to prevent the two pegs 51 from entering the accommodation space 31. Then, when the two buckle holes 42 do not reach the sides of the two first perforations 33 and the external force applied to the clasp 41 is removed, the two slider spring bodies 35 push the two sliders 34 and the clasp 41 to push the clasp 41 away from the sides of the two first perforations 33, and the two sliders 34 move to the sides of the two first perforations 33. At the same time, the clasp 41 and the two sliders 34 slide in the accommodation space 31, the two pegs 51 slide on the second surface 43 of the clasp 41 and slide to the first surfaces 39 of the two sliders 34, so that the two sliders 34 support the two pegs 51 to prevent the two pegs 51 from entering the accommodation space 31.

[0077] It is worth mentioning that the two first perforations 33 are arranged on the first plate portion 321, and the two second perforations 36 are arranged on the second plate portion 322. The arrangement positions of the two second perforations 36 correspond to the two first perforations 33. After the locking portions 511 of the two pegs 51 enter the accommodation space 31, the locking portions 511 not only pass through the two buckle holes 42, but also pass through the two second perforations 36.

[0078] Because the locking portions 511 of the two pegs 51 pass through the two first perforations 33 and the two second perforations 36, the two first perforations 33 and the two second perforations 36 can provide sufficient support force for the locking portions 511, so that the locking portions 511 of the two pegs 51 support the two buckle holes 42 of the clasp 41 and effectively resist the transverse pulling force of the buckle unit 4, which can effectively improve the structural strength of the clasp device.

[0079] The pressing unit 6 includes a pressing body 61 arranged on the main body 32, a pressing spring body 62 abutting against the pressing body 61, support inclined surfaces 63 arranged on the pressing body 61, an unlocking perforation 64 arranged on the pressing body 61, and limiting protrusions 65 arranged on the pressing body 61. The pressing body 61 is arranged between the first plate portion 321, the two third plate portions 323, and the fourth plate portion 324.

[0080] In the first preferred embodiment, the periphery of the pressing body 61 is provided with a light-transmitting portion 22, and a plurality of display modules 84 are arranged on the light-transmitting portion 22. Each display module is a light-emitting diode (LED). The plurality of display modules 84 can be controlled to emit light, and the emitted light can be transmitted outward through the light-transmitting portion 22, thereby prompting the position of the pressing body 61 to the passenger.

[0081] The pressing body 61 can move between a first position (see Fig. 1) Figure 9 ) and a second position (see Fig. 2) Figure 12 ). When the two sliding blocks 34 abut against the bottom ends of the locking portions 511 of the two bolt bodies 51, the pressing body 61 is pushed by the pressing elastic body 62 to the first position and spaced apart from the side wings 513 of the two bolt bodies 51. When the pressing body 61 is in the first position, the locking portions 511 of the two bolt bodies 51 can be pushed into the accommodating space 31.

[0082] When the two bolt bodies 51 enter the accommodating space 31, the side wings 513 of the two bolt bodies 51 abut against the two support inclined surfaces 63. When the pressing body 61 is pressed by an external force, the pressing body 61 can move to the second position. When the pressing body 61 moves from the first position to the second position, the two support inclined surfaces 63 move to the right and support the side wings 513 of the two bolt bodies 51 to move the locking portions 511 out of the accommodating space 31.

[0083] The positions of the plurality of limiting protrusions 65 are matched with the positions of the plurality of stop portions 326. The plurality of limiting protrusions 65 abut against the plurality of stop portions 326, respectively, to limit the moving position of the pressing body 61 in the main body unit 3. The two sides of the pressing elastic body 62 abut against the pressing body 61 and the electromagnetic fixing portion 325, respectively, to push the pressing body 61 to the left. In the preferred embodiment, the number of the limiting protrusions 65 and the number of the stop portions 326 are two, but the actual implementation should not be limited thereto.

[0084] The electromagnetic unit 7 includes two electromagnetic modules 71 arranged in the main body 32, two electromagnetic push rods 72 penetrating the electromagnetic modules 71, and two push rod elastic bodies 73 abutting against the electromagnetic push rods 72. The two electromagnetic push rods 72 each have a magnetic moving portion 721 arranged in the electromagnetic module 71 and two blocking portions 722 connected to the magnetic moving portion 721.

[0085] The two electromagnetic modules 71 are each an electromagnetic coil structure, which is approximately cylindrical with a hole. The two electromagnetic modules 71 are arranged in the two electromagnetic fixing portions 325, respectively. The magnetic moving portions 721 of the two electromagnetic push rods 72 penetrate the cylindrical holes of the two electromagnetic modules 71, respectively, and can be moved by the electromagnetic action of the two electromagnetic modules 71, respectively. Since the technology of moving a magnetic body by electromagnetism is a known technology, it will not be described in detail here.

[0086] The electromagnetic push rod 72 can move between a release position (see Figure 10 ) and a locking position (see Figure 11 ). When the two electromagnetic modules 71 are energized, the two electromagnetic push rods 72 can be moved to the release position, so that the two electromagnetic push rods 72 and the two bolt bodies 51 are spaced apart from each other. When the electromagnetic push rod 72 is in the release position, the pressing body 61 can be moved to the second position and the two bolt bodies 51 are moved out of the accommodation space 31.

[0087] When the two bolt bodies 51 enter the accommodation space 31 and the two electromagnetic modules 71 are not energized, the two push rod elastic bodies 73 push the two electromagnetic push rods 72 to the locking position, respectively, and the two electromagnetic push rods 72 interfere with the two bolt bodies 51, respectively, to prevent the pressing body 61 from pushing the bolt body 51 out of the accommodation space 31.

[0088] Preferably, the two push rod elastic bodies 73 are respectively arranged between the two blocking portions 722 and the electromagnetic modules 71, for respectively pushing the two electromagnetic push rods 72 to move to the locking position. When the two electromagnetic modules 71 are energized, the two electromagnetic push rods 72 can be moved to the release position, respectively. In actual implementation, the two push rod elastic bodies 73 can use other elastic structures, which should not be limited by this.

[0089] The control unit 8 includes a magnetic bolt detection module 81 arranged on the two electromagnetic fixing portions 325 of the main body 32 and used to detect the position of the two electromagnetic push rods 72, a control module 82 electrically connected with the magnetic bolt detection module 81, a control module 82 electrically connected with the control module 82, and a display module 84 electrically connected with the control module 82. The control module 82 is electrically connected with the electromagnetic module 71, and the control module 82 can control the energization state of the electromagnetic module 71 to make the electromagnetic module 71 enter the energized state or the non-energized state.

[0090] When the electromagnetic module 71 is energized, a magnetic force can be generated on the electromagnetic push rod 72 to move the electromagnetic push rod 72 to the release position, and the electromagnetic push rod 72 and the bolt body 51 are spaced apart from each other. When the bolt body 51 enters the accommodation space 31 and the electromagnetic module 71 is not energized, the push rod elastic body 73 pushes the electromagnetic push rod 72 to the locking position, so that the electromagnetic push rod 72 and the bolt body 51 interfere with each other to block the bolt body 51 from leaving the accommodation space 31.

[0091] The control module 82 is a microcontroller which runs a program to control the amusement facility, the buckle device is arranged on the seat in the amusement facility, the control module 83 is an operation panel, and the display module 84 is a plurality of display lights. Preferably, the control module 83 and the display module 84 can be a touch screen. In actual implementation, it should not be limited thereto. In addition, the control module 82 can be electrically connected to the buckle device on a plurality of seats respectively to monitor the safety of a plurality of passengers respectively.

[0092] In the first preferred embodiment, the two magnetic bolt detection modules 81 are infrared detectors which detect whether the output infrared rays are blocked to determine the position of the two electromagnetic push rods 72. For example, when the two electromagnetic modules 71 are energized, the blocking portions 722 of the two electromagnetic push rods 72 are away from the bolt body 51, and the magnetic moving portions 721 of the two electromagnetic push rods 72 move to the right to block the output infrared rays of the two magnetic bolt detection modules 81. Thus, the magnetic bolt detection modules 81 can determine that the two electromagnetic push rods 72 are in the unlocking position. When the two electromagnetic modules 71 are not energized, the two push rod elastic bodies 73 push the two electromagnetic push rods 72 to the left. At this time, the two electromagnetic push rods 72 are away from the two magnetic bolt detection modules 81, and the output infrared rays of the two magnetic bolt detection modules 81 are not blocked. Thus, the control module 82 can determine that the two electromagnetic push rods 72 are in the locking position. Those skilled in the art should understand that the infrared detector can be replaced by any detection means which can achieve the same effect, including but not limited to photoelectric, inductive or mechanical detectors. In the preferred embodiment, the two magnetic bolt detection modules 81 are respectively arranged on the two electromagnetic fixing portions 325 to detect the position of the two electromagnetic push rods 72. In actual implementation, it should not be limited thereto.

[0093] The control module 83 can control the control module 82 to control whether the two electromagnetic modules 71 are energized or not. The display module 84 can display the status of the buckle device. For example, when the staff operates the control module 83 to control the control module 82 to control the two electromagnetic modules 71 to be in the energized state, the display module 84 displays “electromagnetic coil is conducting”. When the magnetic force output by the two electromagnetic modules 71 in the energized state moves the two electromagnetic push rods 72 to the unlocking position, the display module 84 displays “buckle device is in the unlocking state”. When the staff operates the control module 83 to control the control module 82 to control the two electromagnetic modules 71 to be in the non-energized state, the display module 84 displays “electromagnetic coil is de-energized”. When the two electromagnetic modules 71 are in the non-energized state, and the push rod elastic body 73 pushes the two electromagnetic push rods 72 to the locking position, the display module 84 displays “buckle device is in the locking state”. In actual implementation, the display module 84 can output information in other ways. It should not be limited thereto.

[0094] In the first preferred embodiment, the number of the sliding blocks 34, the locking unit 5 and the electromagnetic unit 7 is two, so that when one of the mechanical structures is out of order, the two magnetic bolt detection modules 81 can transmit the detection information to the control module 82, so that the control module 82 can send warning information through the control module 83 and stop the operation of the amusement facility. In practice, the number of the sliding blocks 34, the locking unit 5 and the electromagnetic unit 7 can be one or more than three, which should not be limited by the example of the preferred embodiment.

[0095] When the buckle device is installed, the locking unit 5 and the pressing unit 6 are arranged on the first plate part 321, and then the fourth plate part 324 is locked on the two third plate parts 323 and the electromagnetic fixing part 325, so that the locking unit 5 and the pressing unit 6 are fixed between the first plate part 321, the two third plate parts 323 and the fourth plate part 324. Compared with the early vertical rotating disc structure, the installation steps of the buckle device are relatively simple. When the inventor assembles the buckle with the vertical rotating disc structure, the installation time is about 3-4 hours, while the installation time of the buckle device is about 1-2 hours, which significantly shortens the assembly time and improves the production capacity.

[0096] For reference Figure 9 When the clasp 41 of the buckle unit 4 does not enter the accommodation space 31, the two sliding block elastic bodies 35 push the first surfaces 39 arranged on the two sliding blocks 34 to the position below the two first perforations 33. Since the two sliding guide bodies 38 limit the position of the two sliding blocks 34, the two sliding blocks 34 will not rush out of the accommodation space 31. At this time, the first surfaces 39 arranged on the two sliding blocks 34 abut against the locking parts 511 of the two bolt bodies 51 respectively, so as to block the two locking parts 511 from entering the accommodation space 31.

[0097] The pressing body 61 is pushed by the pressing elastic body 62 to the first position. When the clasp 41 of the buckle unit 4 does not enter the accommodation space 31, even if the pressing body 61 is pressed by external force and moves to the second position, since the locking part 511 of the bolt body 51 does not enter the accommodation space 31, the supporting inclined surface 63 cannot contact the side wing 513 of the bolt body 51, so that the buckle device will not produce any action.

[0098] The control module 82 supplies power to the electromagnetic module 71 to excite the electromagnetic module 71 and generate magnetic force, so as to move the electromagnetic push rod 72 to the release position. When the clasp 41 of the clasp unit 4 does not enter the accommodation space 31, even if the control module 82 cuts off the power supply to the electromagnetic module 71, the two blocking portions 722 of the electromagnetic module 71 are blocked by the two side wings 513 of the pin body 51, so that the electromagnetic push rod 72 cannot be moved to the locking position, and at this time, the buckle device does not produce any action.

[0099] With reference to Figure 10 When the clasp 41 of the clasp unit 4 is pushed into the accommodation space 31, the clasp 41 pushes the two sliders 34 to make the two sliders 34 slide to the right. Since the height of the first surface 39 is consistent with the height of the second surface 43, the bottom end of the locking portion 511 of the pin body 51 changes from abutting against the first surface 39 to abutting against the second surface 43, and finally, the two buckle holes 42 are moved below the locking portion 511 of the pin body 51.

[0100] Since the two buckle holes 42 are below the locking portion 511 of the pin body 51, the positions of the two buckle holes 42 correspond to the two first perforations 33. Since the locking portion 511 of the pin body 51 is not supported by any object, the two lock pin elastic bodies 52 push the two pin bodies 51 to make the locking portion 511 of the pin body 51 enter the two buckle holes 42, in other words, the locking portion 511 of the pin body 51 enters the accommodation space 31. At this time, the locking portion 511 of the pin body 51 interferes with the clasp 41, so that the clasp 41 cannot leave the accommodation space 31.

[0101] With reference to Figure 11 Then, the control module 82 can be controlled to cancel the power supply to the two electromagnetic modules 71, and the two electromagnetic modules 71 do not generate magnetic force, so that the two push rod elastic bodies 73 push the two electromagnetic push rods 72 to the left to make the two electromagnetic push rods 72 move to the locking position.

[0102] When the two electromagnetic push rods 72 are in the locking position, the two blocking portions 722 of the two electromagnetic push rods 72 are above the two side wings 513 of the pin body 51, so that the two blocking portions 722 interfere with the two side wings 513 respectively, so that the two pin bodies 51 cannot be moved upward.

[0103] Because the two pegs 51 have interfered with the buckle 41, and because the two blocking portions 722 have interfered with the two side wings 513 respectively, the pressing body 61 cannot be pressed to the second position by external force, the buckle 41 cannot be detached from the accommodating space 31, and the purpose of double locking can be achieved. Thus, the passenger sitting on the seat can be fixed stably, and in some amusement facilities, the buckle device of the present application can protect the safety of the passenger sitting on the seat. Wherein, the two magnetic peg detection modules 81 must confirm that the two electromagnetic push rods 72 have entered the locking position, and the control module 82 can start the amusement facility, so as to ensure that the passenger is indeed fixed on the seat.

[0104] If the control unit 8 loses power, the control module 82 cannot supply power to the two electromagnetic modules 71, and the passenger sitting on the seat cannot directly unlock the buckle device. At this time, a forced unlocking body (not shown in the figure) can be inserted through the unlocking hole 64, and at the same time, it can touch the pressing body 61 and the two electromagnetic push rods 72 to simultaneously push the pressing body 61 and the two electromagnetic push rods 72, so that the two electromagnetic push rods 72 move from the locking position to the unlocking position, the pressing body 61 moves from the first position to the second position, further drives the two pegs 51 to move upward, and unlocks the interference with the buckle 41. Since the technology of forced unlocking is the same as the known technology, it will not be described in detail here.

[0105] For reference Figure 10 When the passenger wants to leave the seat, the control module 82 can be controlled to supply power to the two electromagnetic modules 71, and the two electromagnetic modules 71 generate external magnetic force. The magnetic moving portion 721 of the two electromagnetic push rods 72 receives the magnetic force to move the two electromagnetic push rods 72 to the unlocking position. At this time, the two blocking portions 722 of the two electromagnetic push rods 72 are away from the upper part of the two side wings 513 of the two pegs 51, and the two electromagnetic push rods 72 do not interfere with the two pegs 51.

[0106] For reference Figure 12 Then, the pressing body 61 is pressed by external force to move the pressing body 61 from the first position to the second position. At this time, the two support inclined surfaces 63 arranged on the pressing body 61 abut against the side wings 513 of the two pegs 51 respectively, and push the two pegs 51 upward. Then, the locking portion 511 of the two pegs 51 is away from the accommodating space 31 and the two buckle holes 42, and the buckle 41 is not interfered, the two slide block elastic bodies 35 push the two slide blocks 34 to push the buckle 41 to the left, and then the first surface 39 of the two slide blocks 34 is located below the two first perforations 33.

[0107] For reference Figure 9, the outer force pressing the pressing body 61 is released, the pressing elastic body 62 pushes the pressing body 61 to move from the second position to the first position, and the rider can move the buckle 41 out of the accommodating space 31 of the main body unit 3. The lock elastic body 52 pushes the bolt body 51 to move towards the accommodating space 31, and at this time, the first surface 39 of the main body unit 3 abuts against the bottom of the locking portion 511 of the bolt body 51 to prevent the bolt body 51 from entering the accommodating space 31.

[0108] Please refer to Figure 13 , Figure 14 and Figure 15 , which is a second preferred embodiment of the buckle device capable of displaying the locking state, and is basically the same as the first preferred embodiment. The same parts are not described in detail, and the different parts are that the buckle unit 4 further comprises a tape 44 connected with the buckle 41 and a winding module 45 connected with the tape 44 and electrically connected with the control module 82. The winding module 45 can wind the tape 44, and the tape 44 can also be pulled out of the winding module 45. The winding module 45 and the main body 32 are separately arranged on the left and right sides of the seat. When the buckle 41 interferes with the bolt body 51, the tape 44 will bind the rider to fix the rider on the seat.

[0109] Please refer to Table 1. The winding module 45 is a one-way electromagnetic winding structure. The control module 82 can conduct electricity to the winding module 45 to control the winding module 45 in the excited state, and can cut off the electricity to the winding module 45 to control the winding module 45 in the non-excited state. When the control module 82 controls the winding module 45 in the non-excited state, the winding module 45 one-way clamps (locked state) the tape 44, so that the winding module 45 can wind the tape 44, but the tape 44 cannot be pulled out of the winding module 45. When the control module 82 controls the winding module 45 in the excited state (unlocked state), the winding module 45 does not clamp the tape 44, so that the winding module 45 can wind the tape 44, and the tape 44 can be pulled out of the winding module 45.

[0111] Table 1

[0112] Please refer to Table II, in the second preferred embodiment, when the latch 51 does not interfere with the buckle 41, and the electromagnetic push rod 72 is located at the release position, and the winding module 45 is in the energized state, it indicates that the passenger has not inserted the buckle 41 into the accommodation space 31, at this time, the control module 82 does not matter whether the electromagnetic module 71 is controlled in the energized state or the non-energized state, the electromagnetic push rod 72 will only be limited in the release position, and the control module 82 controls the winding module 45 in the energized state, at this time, the display module 84 displays the first state information. When the latch 51 interferes with the buckle 41, and the electromagnetic module 71 is in the non-energized state, and the winding module 45 is in the energized state, it indicates that the passenger has inserted the buckle 41 into the accommodation space 31, and the control module 82 controls the electromagnetic module 71 in the non-energized state, but the winding module 45 is still controlled in the energized state, at this time, the user can still adjust the length of the winding tape 44, the display module 84 displays the second state information. When the latch 51 interferes with the buckle 41, and the electromagnetic module 71 is in the non-energized state, and the winding module 45 is in the non-energized state, it indicates that the passenger has inserted the buckle 41 into the accommodation space 31, and the control module 82 controls the electromagnetic module 71 and the winding module 45 in the non-energized state, at this time, the user has already been unable to pull out the winding tape 44 from the winding module 45, the display module 84 displays the third state information.

[0113]

[0114]

[0115] Table II

[0116] In the second preferred embodiment, the display module 84 is a plurality of light emitting elements arranged on the main body 32, preferably, the plurality of light emitting elements are full-color type light emitting diodes (RGB LED), the control module 82 can control the display module 84 to output different light effects according to the first state information, the second state information and the third state information, for example, when the first state information is described above, the control module 82 controls the display module 84 to output a breathing light effect, when the second state information is described above, the control module 82 controls the display module 84 to output a constant light effect, when the third state information is described above, the control module 82 controls the display module 84 to output an extinguished light effect, in actual implementation, the display module 84 can also display other light effects, for example, not lighting is also a change in light effect, which should not be limited thereto.

[0117] In the second preferred embodiment, the housing unit 2 further comprises a light-transmitting portion 22 arranged on the housing 21 and an unlocking opening 23 arranged on the housing 21, the light-transmitting portion 22 is arranged on the housing 21 at the outer edge of the unlocking opening 23, the pressing body 61 is exposed outside through the unlocking opening 23, and the accommodating space 31 is exposed outside through the unlocking opening 23, so that the clasp 41 can enter or exit the accommodating space 31 through the unlocking opening 23.

[0118] The display module 84 is arranged close to the light-transmitting portion 22 or directly on the light-transmitting portion 22, the light emitted by the display module 84 can be exposed outside through the light-transmitting portion 22, and since the light-transmitting portion 22 frames the unlocking opening 23, when the light emitted by the display module 84 is emitted outside through the light-transmitting portion 22, the passenger can easily insert the clasp 41 into the accommodating space 31 or confirm the position of the pressing body 61 and press the fastener device in a dim environment.

[0119] Please refer to Figure 16 and Figure 17 for a third preferred embodiment of the fastener device capable of displaying the locking state, the third preferred embodiment is substantially the same as the second preferred embodiment, and the same parts will not be described in detail, and the different parts are that the control unit 8 further comprises a clasp detection module 85 arranged on the main body 32 and electrically connected with the control module 82, the clasp detection module 85 is used to detect whether the clasp 41 is arranged in the accommodating space 31, for example, when the clasp detection module 85 detects the clasp 41, it indicates that the clasp 41 has been inserted into the accommodating space 31, and when the clasp detection module 85 does not detect the clasp 41, it indicates that the clasp 41 has left the accommodating space 31, and in actual implementation, the clasp detection module 85 can also determine whether the clasp 41 has been inserted into the accommodating space 31 according to the interference relationship between the shank 51 and the clasp 41, for example, the clasp detection module 85 can determine the position of the clasp 41 according to whether the locking portion 511 of the shank 51 is inserted into the second through hole 36, and this should not be limited.

[0120] Please refer to Table III, the control module 82 receives the detection information of the buckle detection module 85 and controls the display module 84 to display the state information according to whether the buckle 41 is arranged in the accommodating space 31, for example, when the buckle detection module 85 detects that the buckle 41 is not arranged in the accommodating space 31 and the electromagnetic module 71 is in the excited state, it indicates that the passenger has not inserted the buckle 41 into the accommodating space 31, the control module 82 controls the electromagnetic module 71 to be in the excited state, and the output electromagnetic force moves the electromagnetic push rod 72 to the release position, at this time the display module 84 displays the first state information; when the buckle detection module 85 detects that the buckle 41 is arranged in the accommodating space 31 and the electromagnetic module 71 is in the excited state, it indicates that the passenger has inserted the buckle 41 into the accommodating space 31, the control module 82 controls the electromagnetic module 71 to be in the excited state, and the output electromagnetic force moves the electromagnetic push rod 72 to the release position, at this time the display module 84 displays the second state information; when the buckle detection module 85 detects that the buckle 41 is arranged in the accommodating space 31 and the electromagnetic module 71 is in the unexcited state, it indicates that the passenger has inserted the buckle 41 into the accommodating space 31, the control module 82 controls the electromagnetic module 71 to be in the unexcited state, and the push rod spring 73 pushes the electromagnetic push rod 72 to the locked position, at this time the display module 84 displays the third state information.

[0121]

[0122] Table III

[0123] In the third preferred embodiment, the display module 84 is a plurality of light emitting elements arranged in the main body 32, in actual implementation, the number of the display module 84 should be arranged according to the actual situation, which should not be limited, preferably, the plurality of light emitting elements are full-color type light emitting diodes (RGB LED), the control module 82 can control the display module 84 to output different light effects according to the first state information, the second state information and the third state information, for example, when the first state information is output, the control module 82 controls the display module 84 to output the light effect such as breathing, when the second state information is output, the control module 82 controls the display module 84 to output the light effect such as constant brightness, and when the third state information is output, the control module 82 controls the display module 84 to output the light effect such as extinguishing, in actual implementation, the display module 84 can also display other light effects, for example, not lighting is also a change of light effect, which should not be limited.

[0124] In the third preferred embodiment, the pressing body 61 is made of a light-transmitting material, and the display module 84 is arranged close to the pressing body 61, so that the light emitted by the display module 84 can be transmitted outwards through the pressing body 84. In actual implementation, the light-transmitting part 22 of the housing 21 or the plurality of display modules 84 arranged on the light-transmitting part 22 in the second preferred embodiment can be combined, and the light emitted by the display module 84 can be transmitted outwards through the pressing body 61. In this way, the pressing body 61 can output the state information of the fastener device by means of light, which should not be limited in this way.

[0125] As can be seen from the above description, the fastener device capable of displaying the locking state indeed has the following effects:

[0126] I. Displaying the position in a dim environment:

[0127] The light-transmitting part 22 surrounds the unlocking opening 23, and the light emitted by the display module 84 can be transmitted outwards through the light-transmitting part 22. In a dim environment, not only the position of the fastener device can be displayed, but also the position of the unlocking opening 23 can be displayed, so that the passenger can easily insert the buckle 41 into the accommodating space 31 through the unlocking opening 23.

[0128] II. Confirming the locking state from the display light effect:

[0129] The display module 84 can display corresponding light effects according to different locking states. The staff only needs to confirm the displayed light effect to confirm the locking state of the fastener device, and the locking state does not need to be confirmed by pressing the pressing body 61 in a touching manner.

[0130] III. Preventing the spread of bacteria:

[0131] As can be seen from the above description, since the staff does not need to confirm the locking state of the fastener device in a touching manner, the staff can maintain a distance from the passenger, thereby preventing the spread of bacteria.

[0132] IV. Improving production efficiency:

[0133] The assembly method of the present application is to stack one layer after another. The spring is relatively simple to arrange, the structure will not slide, and the fastener device can be quickly assembled, thereby effectively improving the production efficiency of the fastener device.

[0134] V. Preventing pressing:

[0135] When the two electromagnetic push rods 72 are located at the locking position, the two blocking parts 722 of the two electromagnetic push rods 72 interfere with the two side wings 513 of the two bolt bodies 51, thereby resisting the pressing of the pressing body 61 by external force.

[0136] VI. Structure strength enhancement:

[0137] In the buckle device, the two bolt bodies 51 move in a straight up and down manner, the two bolt guide bodies 53 effectively control the moving position of the two bolt bodies 51 and provide support strength, and the two first through holes 33 and the two second through holes 36 simultaneously support the locking part 511 of the bolt body 51. Compared with the early rotating structure of the vertical chuck, the two bolt bodies 51 can withstand greater pulling force, so that the buckle unit 4 is not easy to be separated from the accommodation space 31.
