Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and in particular to an anti-theft sensor, an anti-theft structure and a lamp. Background Art

[0002] Common induction lights usually include lamps and sensors. When the sensor senses a vehicle or person approaching, it will drive the lamp to turn on for lighting. After the vehicle or person leaves for a period of time, the lamp will turn off automatically, achieving the goal of "the light turns on when someone arrives and turns off when someone leaves". It is energy-saving and environmentally friendly, and is now widely used in various places.

[0003] In order to make the sensor more accurately sense the location information of vehicles or people, most existing sensor lamps install the sensor outside the lamp housing, and the installation method is mostly conventional detachable installation methods such as snap-on or screw-on. At this time, anyone can easily remove the sensor from the lamp housing and take it away. Therefore, in public places such as underground parking lots, the sensor is often removed and stolen, causing property losses. If the structure of integrating the sensor into the lamp housing is adopted, although the problem of frequent sensor theft can be solved, when the sensor is damaged, the sensor and the lamp housing need to be replaced together, which increases the subsequent maintenance cost.

[0034] In order to further understand the application content, features and effects of the present application, the following embodiments are cited and described in detail with reference to the accompanying drawings.

[0035] Embodiment 1:

[0036] Reference Figure 1-Figure 2 , Figure 1 is a schematic diagram of the structure of the anti-theft sensor in the first embodiment, Figure 2 This is another structural schematic diagram of the anti-theft sensor in the first embodiment. The anti-theft sensor in this embodiment includes a carrier 1, a sensing member 2 and a locking member 3. The carrier 1 has a receiving opening 11, and a protrusion 111 is provided on the inner wall of the receiving opening 11. The sensing member 2 is movably arranged in the receiving opening 11, and a locking groove 221 is provided on the outer surface of the sensing member 2. An opening 2211 is provided at one end of the locking groove 221, and the locking groove 221 and the opening 2211 are both adapted to the protrusion 111. The locking end of the locking member 3 faces the outer surface of the sensing member 2. In the locked state, the protrusion 111 is clamped in the locking groove 221, and the locking end extends into the locking groove 221, and blocks the protrusion 111 from escaping from the locking groove 221 through the opening 2211.

[0037] The anti-theft sensor in this embodiment is applied to the lamp, and the sensor 2 is installed on the lamp through the carrier 1 and electrically connected to the circuit board of the lamp to realize intelligent control of the lamp to switch on and off. After the sensor 2 is installed in the receiving opening 11, through the setting of the locking member 3, the locking end of the locking member 3 can be extended into the locking groove 221, and the protrusion 111 is blocked from escaping from the locking groove 221 through the opening 2211, so that the sensor 2 is locked and fixed on the carrier 1 or the sensor 2 can move slightly on the carrier 1 but cannot be removed from the carrier 1, so that the sensor 2 cannot be easily removed from the carrier 1, that is, the sensor 2 cannot be easily removed from the lamp, and when the lamp is set in a public place, the theft of the sensor 2 can be effectively avoided, and property loss and maintenance costs can be reduced.

[0038] Reference Figure 3 and Figure 4 , Figure 3 is a schematic diagram of the structure of the induction element in the first embodiment, Figure 4 This is a schematic diagram of the structure of the bearing member in the first embodiment. Preferably, the sensing member 2 includes a sensing bearing shell 21, a mounting block 22 and a sensor. The mounting block 22 is arranged at the bottom of the bearing shell 21. The sensor is fixed to the bearing shell 21. The outer surface of the mounting block 22 is provided with a locking groove 221. In specific application, the receiving opening 11 on the bearing member 1 is a two-stage stepped hole, including a large hole and a small hole that are interconnected, wherein the sensing bearing shell 21 is arranged in the large hole of the receiving opening 11, the mounting block 22 is located in the small hole of the mounting block receiving opening 11, and the protrusion 111 is arranged on the inner wall of the small hole. A locking notch 112 is also provided on the inner wall of the small hole. It can be understood that, in the locked state, the locking end of the locking member 3 passes through the locking notch 112 and extends into the locking groove 221, preventing the protrusion 111 from escaping from the locking groove 221 from the opening. The sensor is integrally formed with the sensor carrying shell 21 , so that no one can remove the sensor from the sensor carrying shell 21 , and a connecting pin is provided at the bottom of the sensor for electrically connecting with the circuit board of the lamp.

[0039] Refer to Figure 3 and Figure 5 , Figure 5The diagram is a diagram of the matching of the bearing member and the locking member in the first embodiment. Preferably, the locking groove 221 includes a longitudinal groove 2212 and a transverse groove 2213. The longitudinal groove 2212 and the transverse groove 2213 are both provided on the outer surface of the sensing member 2. One end of the longitudinal groove 2212 is an opening 2211, and the other end of the longitudinal groove 2212 is connected to the transverse groove 2213. In the locked state, the protrusion 111 is limitedly fixed in the transverse groove 2213, and the locking end extends into the longitudinal groove 2212. When the sensing member 2 needs to be installed on the bearing member 1, the opening 2211 is aligned with the protrusion 111, so that the protrusion 111 passes through the opening 2211 and enters the longitudinal groove 2212, and then the sensing member 2 is rotated so that the protrusion 111 moves along the longitudinal groove 2212 into the transverse groove 2213. When the protrusion 111 is located in the transverse groove 2213, the locking member 3 is driven so that its locking end passes through the locking notch 112 and extends into the longitudinal groove 2212, specifically, into the connection between the longitudinal groove 2212 and the transverse groove 2213. At this time, The protrusion 111 is blocked by the locking end and fixed in position in the transverse groove 2213. That is to say, at this time, since the protrusion 111 is located in the transverse groove 2213, the transverse groove 2213 limits the protrusion 111, so that the sensing member 2 cannot move in the longitudinal direction, and because the locking end blocks the protrusion 111, the sensing member 2 cannot rotate, so the sensing member 2 is locked and fixed on the carrier 1, so that the sensing member 2 cannot be easily disassembled and removed, avoiding the risk of frequent theft and improving safety. Furthermore, the number of protrusions 111 and locking grooves 221 are both multiple, and multiple protrusions 111 are spaced apart on the inner wall of the receiving port 11, and multiple locking grooves 221 are spaced apart on the outer surface of the sensing member 2, and each protrusion 111 is corresponding to a locking groove 221. By providing a plurality of protrusions 111 and a plurality of locking grooves 221, when the sensing element 2 is locked, the locking stability of the sensing element 2 can be effectively improved, so that it is not easy to shake after being installed on the supporting element 1, and the difficulty of forcibly removing and stealing the sensing element 2 in the locked state is increased, thereby improving safety.

[0040] Review Figure 1-Figure 5Preferably, the locking member 3 includes a locking block 31, a pull rod 32 and a spring 33. The pull rod 32 is movably arranged on the carrier 1 along a direction perpendicular to the bottom of the locking groove 221. The locking block 31 is arranged at one end of the pull rod 32 close to the locking groove 221. The spring 33 is sleeved outside the pull rod 32, and the two ends of the spring 33 are respectively connected to the carrier 1 and the locking block 31. Of course, in other embodiments, other elastic components can be used instead of the spring 33. In the locked state, the elastic force of the spring 33 pushes the locking block 31 into the locking groove 221, and the protrusion 111 and the locking block 31 cooperate to lock the sensor 2 on the carrier 1. In specific application, the locking end of the locking member 3 described in this embodiment refers to the locking block 31. When the sensing member 2 needs to be removed from the carrier 1, it is only necessary to pull the pull rod 32 in the direction away from the locking groove 221, so that the spring 33 is compressed, thereby driving the locking block 31 away from the locking groove 221, and the protrusion 111 loses the blocking effect of the locking block 31. The protrusion 111 can be separated from the locking groove 221 through the opening 2211, that is, at this time, it is only necessary to rotate the sensing member 2 to remove the sensing member 2 from the receiving port 11, that is, to realize the removal of the sensing member 2 from the carrier 1, which is convenient for the replacement or maintenance of the sensing member 2 and reduces the later maintenance cost. Furthermore, a first pushing inclined surface 222 is provided at the bottom of the sensing member 2, and a second pushing inclined surface 311 is provided at the position corresponding to the pushing inclined surface 222 of the locking block 31, and the first pushing inclined surface 222 and the second pushing inclined surface 311 can slide relative to each other. It should be noted that the plurality of protrusions 111 and the locking block 31 are staggered, that is, the locking notch 112 and the plurality of protrusions 111 are staggered and spaced on the inner wall of the receiving opening 11. It is understandable that when the sensing member 2 is installed on the carrier 1, the sensing member 2 is first placed in the receiving opening 11 so that the protrusion 111 is directly opposite to the opening 2211. At this time, the bottom of the sensing member 2, that is, the bottom of the mounting block 22, contacts the locking block 31. As the sensing member 2 extends into the receiving opening 11, the protrusion 111 enters the longitudinal groove 2212 through the opening 2211, and the first pushing inclined surface 222 at the bottom of the mounting block 22 and the second pushing inclined surface 311 of the locking block 31 first fit and then slide relative to each other. During the extension of the sensing member 2, the mounting block 22 pushes the locking block 31 to compress the spring 33 and move in a direction away from the locking groove 221. At this time, the locking block 31 contacts the outer surface of the mounting block 22, that is, the locking block 31 does not enter the longitudinal groove 2212. When the protrusion 111 is located at the specified position of the longitudinal groove 2212, the rotating sensing member 2 causes the protrusion 111 to move into the transverse groove 2213, and as the sensing member 2 rotates, the locking block 31 rotates from the outer surface of the mounting block 22 to face the longitudinal groove 2212 on the mounting block 22. Under the push of the restoring elastic force of the spring 33, the locking block 31 extends into the longitudinal groove 2212 and blocks the protrusion 111 so that it is limited and fixed in the transverse groove 2213, thereby completing the locking installation process of the sensing member 2. The installation process is simple and the locking is reliable.

[0041] Embodiment 2:

[0042] Reference Figure 6-Figure 8 , Figure 6 is a schematic diagram of the structure of the anti-theft structure in the second embodiment, Figure 7 is another structural schematic diagram of the anti-theft structure in the second embodiment, Figure 8 Schematic diagram of the structure of the housing member in the second embodiment. The anti-theft structure in this embodiment includes a housing member 4 and the anti-theft sensor in the first embodiment. The housing member 4 is provided with an installation opening 41 on its surface. The housing member 4 has a wiring harness storage space. The carrier 1 is provided in the installation opening 41. The receiving opening 11 is connected to the wiring harness storage space. The locking member 3 is located in the wiring harness storage space.

[0043] Specifically, the anti-theft structure in this embodiment can be directly installed on one end of the lamp, and the wiring harness storage space can store the wiring harness on the lamp, and the locking member 3 is arranged in the wiring harness storage space, that is, located inside the shell member 4, so that no one can pull the pull rod 32 from the outside to unlock the sensing member 2, thereby preventing the sensing member 2 from being easily removed from the shell member 4. Moreover, since the locking member 3 is arranged inside the shell member 4, the position of the locking member 3 cannot be seen when observing only from the outside of the lamp, that is, ordinary people cannot easily find the locking member 3, so that they cannot pull the pull rod 32 to unlock the sensing member 2. In this embodiment, the carrier 1 is a sensor mounting seat. When the carrier 1 is placed in the mounting opening 41, the carrier 1 can be fixed in the mounting opening 41 by injecting glue, so that the carrier 1 and the shell part 4 are fixed as one, thereby improving the stability of the connection. It should be noted that before the carrier 1 is fixed to the shell part 4, the shell part 4 and the carrier 1 are two separate components. In this way, by making them separately, the difficulty of making the shell part 4 and the carrier 1 can be reduced.

[0044] Review Figure 6-Figure 8Preferably, the housing 4 further comprises an anti-theft shell 42, a disassembly shell 43 and a harness locking portion 44. The surface of the anti-theft shell 42 is provided with an installation port 41, and the anti-theft shell 42 has a harness storage space. The disassembly shell 43 is detachably connected to the anti-theft shell 42. The harness locking portion 44 is arranged at one end of the disassembly shell 43 away from the anti-theft shell 42. The harness locking portion 44 has a harness through hole 441, and locks or releases the harness in the harness through hole 441. In specific applications, the anti-theft shell 42 is arranged at one end of the lamp, and the harness on the lamp is stored in the anti-theft shell 42 and the disassembly shell 43, and can pass through the harness through hole 441 to the outside of the disassembly shell 43 and then connect to an external power source. Buckles 431 are provided on both sides of the disassembly shell 43, and slots are provided at positions corresponding to the buckles 431 of the anti-theft shell 42. The buckles 431 can be correspondingly connected to the slots, so that the anti-theft shell 42 and the disassembly shell 43 can be connected and fixed or disassembled and separated. The buckles 431 and the slots in this embodiment are used in conjunction with the quick locking structure in the prior art, which facilitates the quick installation and removal of the anti-theft shell 42 and the disassembly shell 43; of course, other existing detachable structures can also be used, which will not be elaborated in detail here. In other words, if you want to pull the pull rod 32 to remove the sensor 2, you need to perform the following steps: loosen the locking of the wire harness locking part 44 on the wire harness, pull the buckle 431 out of the slot, separate the disassembly shell 43 from the anti-theft shell 42, expose the locking member 3 located inside the anti-theft shell 42, pull the pull rod 32 to unlock the sensor 2, and rotate the sensor 2 to remove it from the anti-theft shell 42. Furthermore, a disassembly opening 4311 is provided on the buckle 431, and the disassembly opening 4311 is flat and small in size. When the buckle 431 is snapped and fixed in the slot, since the disassembly opening 4311 is flat and small in size, it is impossible to reach into the disassembly opening 4311 with bare hands, that is, the buckle cannot be opened with bare hands, and a disassembly tool is required. This further increases the difficulty for thieves to disassemble the sensor 2, thereby improving safety.

[0045] Embodiment three:

[0046] Reference Fig. 9 , Fig. 9 This is a schematic diagram of the anti-theft structure in the third embodiment. The difference between the anti-theft structure in this embodiment and the second embodiment is that the sensor 2 is not installed on the carrier 1 in this embodiment. When the sensor 2 is disassembled for maintenance or on a lamp that does not need to be installed with the sensor 2, the installation opening 41 can be completely closed by installing the cover member 5 on the carrier 1 to prevent dust or insects from entering the shell member 4 and causing damage to the wiring harness or lamp. Specifically, the cover member 5 includes a cover body and a mounting body, wherein the mounting body is arranged at the bottom of the cover body, and the cover body completely closes the mounting opening 41. The structure and function of the mounting body are similar to those of the mounting block 22, and will not be repeated here.

[0047] Embodiment 4:

[0048] Reference Fig.10 , Fig.10 This is a schematic diagram of the structure of the lamp in Example 4. The lamp in this embodiment includes a lamp body and the anti-theft structure in Example 2, wherein the anti-theft structure is connected to one end of the lamp body, and the wiring harness on the lamp body is stored in the wiring harness storage space and can pass through the wiring harness through hole 441 to the outside of the disassembly shell 43 and then connect to an external power supply.

[0049] In summary, after the sensing element is installed in the receiving opening, the locking end of the locking element can be extended into the locking groove through the setting of the locking element, and the protrusion is blocked from escaping from the locking groove through the opening, so that the sensing element is locked and fixed on the supporting element, so that the sensing element cannot be easily removed from the supporting element, that is, the sensing element cannot be easily removed from the lamp. When the lamp is set in a public place, the theft of the sensing element can be effectively avoided, and property loss and maintenance costs can be reduced. At the same time, the unlocking of the sensing element can be achieved by pulling the pull rod, so that the sensing element can be locked and fixed, and can also be unlocked and disassembled. When the sensing element is maintained or replaced, there is no need to replace the entire lamp, which reduces the difficulty of maintenance. In addition, since the locking element is set inside the shell part, it is well concealed. The pull rod cannot be directly pulled from the outside of the shell part to unlock the sensing element. The shell part needs to be disassembled first, and the pull rod is pulled from the inside to unlock it, which further improves the anti-theft effect and safety.

For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
