Description
Technical Field
[0001] The utility model relates to the technical field of backpack accessories, in particular to a buckle and a backpack with vibration and luminous functions. Background Art
[0002] A vibration luminous device is a device that relies on a magnet to pass through an induction coil back and forth, thereby generating magnetoelectricity to light up the luminous part. The reciprocating movement of the magnet is achieved by manually shaking the device, or by following the carrier's running and other actions. The vibration luminous device can be used without a power source, and can be used as a warning light at night. It is increasingly favored by people who like night running or outdoor sports. At present, vibration luminous devices are mostly used by clamping clothes or backpacks. Because the device clamped on the edge of the clothes is likely to give the carrier a foreign body sensation, this method is rarely used, and more often the device is clamped on a backpack for use. The places where backpacks can be clamped are generally only the edges of the pockets on both sides, the straps, and some thinner handles. However, clamping the vibration luminous device in these places is likely to cause interference, affecting the normal use of the backpack. Moreover, if the device is clamped on the straps, it is easy to slip, and if it is clamped on the handles, it is not conducive to the reciprocating movement of the magnet, affecting the luminous effect.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0035] Embodiment 1
[0036] like Figures 1 to 8 As shown, this embodiment discloses a buckle with a vibration luminous function, which includes a vibration luminous device 10 and a connecting assembly. The vibration luminous device 10 includes a housing, an induction magnet 13, an induction coil 14, a luminous member 15, two boundary magnets 16 and two buffer pads 17. The housing includes a first shell 11 and a second shell 12. The first shell 11 is partially inserted into the second shell 12, and the first shell 11 and the second shell 12 are detachably connected, and can be connected by snaps, screws, etc. This arrangement can ensure the connection strength of the first shell 11 and the second shell 12. A slide 111 is provided on the first shell 11, which is a chamber with a one-way opening. When the first shell 11 and the second shell 12 are connected, the second shell 12 blocks the opening of the slide 111.
[0037] The induction magnet 13 is slidably connected in the slideway 111. In order to avoid the air resistance generated during the movement of the induction magnet 13, and at the same time reduce the contact area between the induction magnet 13 and the slideway 111, reduce friction, and facilitate the smooth sliding of the induction magnet 13, a plurality of ventilation grooves 112 are provided on the inner wall of the slideway 111, and the length direction of the ventilation grooves 112 is parallel to the length direction of the slideway 111. Two boundary magnets 16 are respectively placed at both ends of the slideway 111, and the boundary magnets 16 and the induction magnet 13 repel each other, so that the range of motion of the induction magnet 13 can be limited, so that the induction magnet 13 can reverse and move more smoothly, and the response sensitivity of the device can be improved. Two buffer pads 17 are also respectively placed at both ends of the slideway 111, and the buffer pads 17 are placed between the boundary magnets 16 and the induction magnet 13. By setting the buffer pads 17, the impact can be effectively reduced and the noise can be eliminated.
[0038] The induction coil 14 is sleeved on the outer periphery of the first shell 11. The outer periphery of the first shell 11 is provided with a retaining ring 113. The retaining ring 113 cooperates with the second shell 12 to limit the induction coil 14, thereby ensuring that the position of the induction coil 14 on the shell is stable. The induction magnet 13 can reciprocate through the induction coil 14, thereby generating electricity. The second shell 12 is provided with a light-transmitting area 121 and an opening groove 122 corresponding to the light-emitting component 15. The light-emitting component 15 is installed in the opening groove 122. The light emitted by the light-emitting component 15 is transmitted to the outside of the shell through the light-transmitting area 121. The opening groove 122 is detachably blocked by a cover plate 123. Such a setting can facilitate the installation of the light-emitting component 15. When the first shell 11 and the second shell 12 are connected by a snap-fit connection, the cover plate 123 can also shield it to avoid accidental pressing on the snap-fit and causing the first shell 11 and the second shell 12 to separate.
[0039] The light-emitting element 15 is electrically connected to the induction coil 14 . When the sub-induction magnet 13 repeatedly passes through the induction coil 14 , the generated electric energy can light up the light-emitting element 15 .
[0040] The connecting assembly includes a first connecting member 21 and a second connecting member 22. The first connecting member 21 is connected to the second shell 12. Of course, the first connecting member 21 can also be connected to the first shell 11, but it is less likely to cause interference when the first connecting member 21 is connected to the second shell 12. In this embodiment, the first connecting member 21 and the second shell 12 are integrally formed, so that the assembly of the two can be avoided, and the connection relationship between the vibration light-emitting device 10 and the first connecting member 21 is also more reliable.
[0041] The second connecting member 22 is detachably connected to the first connecting member 21. In this embodiment, the first connecting member 21 is integrally formed with a first pin connector 23 and a first clamp connector 24, and the second connecting member 22 is integrally formed with a second pin connector 25 that is pin-jointed with the first pin connector 23 and a second clamp connector 26 that is clamped with the first clamp connector 24. More specifically, the second clamp connector 26 is a slot, and the first clamp connector 24 is a stopper. The second pin connector 25 includes two pin plates 251 that are spaced apart and arranged opposite to each other, the pin plates 251 are placed in the slot, and the pin plates 251 are connected to two adjacent groove walls in the slot. The first pin connector 23 includes a connecting block 231 and a limiting block 232. The limiting block 232 is connected to the first connector 21 through the connecting block 231. A slot corresponding to the pin plate 251 is formed between the limiting block 232 and the first connector 21. The slot width of the slot is adapted to the thickness of the pin plate 251. The limiting block 232 can pass through the gap between the two pin plates 251, and the pin plate 251 can be inserted into the slot. When connecting, the first pin connector 23 is first inserted into the slot, and then the first pin connector 23 is moved relative to the second pin connector 25. When the pin plate 251 is fully inserted into the slot, the stopper abuts against the slot wall of the slot, thereby realizing the relative locking of the first connector 21 and the second connector 22. When disassembling, the external force forces the stopper to withdraw from the slot, and the pin plate 251 can withdraw from the slot, thereby realizing disassembly. The first connector 21 and the second connector 22 thus arranged can be quickly connected or disassembled, and the connection is reliable. By limiting the position of the second connecting member 22 relative to the external component through the cooperation of the pin plate 251 and the card slot, and when the vibration light-emitting device 10 swings with a large amplitude, the first connecting member 21 and the second connecting member 22 can also ensure good tightness and will not be easily disengaged.
[0042] In the first connector 21 and the second connector 22, at least the second connector 22 is provided with a connecting portion 27 for connecting with an external component. Preferably, both the first connector 21 and the second connector 22 are provided with at least one connecting portion 27, and more preferably, the connecting portion 27 is a hole. By providing the connecting portion 27 on both the first connector 21 and the second connector 22, the installation stability of the vibration light-emitting device 10 can be further enhanced. The connecting portion 27 is a hole, which can be connected to the external component by riveting, sewing, hot melting, binding, etc., which has better connectivity and is easier to combine and connect with the external component.
[0043] Embodiment 2
[0044] The difference between this embodiment and the first embodiment is that the first connecting member 21 is detachably connected to the second housing 12, such as by snap connection, buckle connection, screw connection, etc. The first connecting member 21 is detachably connected to the vibration light-emitting device 10, so that when the first connecting member 21 is worn or damaged, it is convenient to replace it, thereby reducing maintenance costs.
[0045] Embodiment 3
[0046] like Fig. 9 and Fig.10 As shown, this embodiment discloses a backpack, which includes a backpack body 30 and the buckle as described in the first or second embodiment, wherein the second connector 22 is directly fixed under the handle of the backpack by riveting or sewing. After such arrangement, the position of the second connector 22 on the backpack body 30 can be very stable, which is conducive to ensuring the position of the vibration light-emitting device 10 and facilitating the vibration light-emitting device 10 to play its role. At this time, the connecting portion 27 may not be provided on the first connector 21.
[0047] In addition, in this embodiment, because the first connecting member 21 is not connected to the backpack body 30, the length direction of the slideway 111 is required to be perpendicular to the connection direction of the connecting assembly to prevent the vibration light-emitting device from swinging too much and causing the first connecting member 21 to be disconnected from the second connecting member. In addition, the hole type and number of the holes on the second connecting member 22 may not be limited to Fig.10 In the style shown, for example, when the second connecting member 22 is connected to the backpack body 30 by riveting, two connecting parts 27 can be provided, and they are circular holes with smaller diameters; for another example, when the second connecting member 22 is connected to the backpack body 30 by sewing, the connecting parts 27 can be four, and they are circular holes with smaller diameters. In this case, the second connecting member 22 is sewn as a button.
[0048] Embodiment 4
[0049] The difference between this embodiment and the third embodiment is that the backpack body 30 has one or two shoulder straps 31, at least one of the shoulder straps 31 includes a first shoulder strap segment 311 and a second shoulder strap segment 312, the first shoulder strap segment 311 is connected to the connecting portion 27 on the first connecting member 21, the first shoulder strap segment 311 can be connected to the first connecting member 21 in a threading and winding manner, so that the first shoulder strap segment 311 can be adjusted in length, and the second shoulder strap segment 312 is connected to the connecting portion 27 on the second connecting member 22. Of course, the first shoulder strap segment 311 can be connected to the second connecting member 22, and the second shoulder strap segment 312 can be connected to the first connecting member 21. This arrangement allows the connecting component to be used as an adjustment buckle for the shoulder strap 31, and can also segment the shoulder strap 31, achieving multiple goals at one stroke. It can also ensure that the connecting component is not easy to come off when the shoulder strap 31 is pulled. Fig.11 As shown, the backpack body 30 has two straps 31, the left strap 31 is provided with a vibration light-emitting device 10 and a connecting component, and the right strap 31 is provided with only a connecting component, which is used as an adjustment buckle of the strap 31. When the consumer carries the backpack, the first strap segment 311 and the second strap segment 312 are tightened to each other, and the connecting component will not be easily detached.
[0050] Embodiment 5
[0051] like Fig.12 and Fig.13 As shown, the difference between this embodiment and the third embodiment is that a first connecting belt 32 and a second connecting belt 33 are provided on the backpack body 30, and the first connecting belt 32 is connected to the connecting portion 27 on the first connecting member 21, and the second connecting belt 33 is connected to the connecting portion 27 on the second connecting member 22. The first connecting belt 32 can be connected to the first connecting member 21 in a threading and winding manner, so that the length of the first connecting belt 32 can be adjusted. Of course, the second connecting belt 33 can also be connected to the second connecting member 22 in a threading and winding manner. In addition, the second connecting belt 33 is not provided, and the second connecting member 22 can be directly anchored to the backpack body 30, which can be flexibly adjusted according to actual needs. This arrangement can make the installation position of the vibration light-emitting device more flexible, and the first connecting belt 32 and the second connecting belt 33 can also be used to hang other accessories to enhance the functionality of the backpack. For example, the first connecting belt 32 and the second connecting belt 33 are respectively arranged on the two sides of the backpack body 30 away from the human body. In this case, the length direction of the slideway 111 and the connection direction of the connecting assembly are required to be arranged perpendicular to each other to ensure that the vibration light-emitting device 10 can play its role; of course, the first connecting belt 32 and the second connecting belt 33 can also be arranged at the upper and lower ends of the backpack body 30 away from the human body. In this case, the length direction of the slideway 111 and the connection direction of the connecting assembly are required to be arranged parallel to each other to ensure that the vibration light-emitting device 10 can play its role. In addition, by tightening the first connecting belt 32, the connecting assembly will not be easily disengaged.
[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
