Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Specifically, the embodiment of the invention provides a protective cap meeting ZHAGA structural specifications, which can be mounted on a socket body meeting ZHAGA structural standards, and it is to be noted that the protective cap structure in the embodiment is the same as the connection structure of the protective cap in ZHAGA BOOK, and the embodiment of the invention is not further described in the structural details of the standard, and the invention aims to realize the increase of the number of connection ports on the basis of the protective cap structure in the existing ZHAGA BOOK standard without affecting the mounting interchangeability of the protective cap structure so as to meet more diversified and rich functions.

Specifically, the protective cap according to the embodiment of the present invention includes a cap body 301, a circuit board 303, a metal sheet 201 and a middle post 306, and specifically, the structure of the cap body 301 except for the middle post 306 is implemented according to ZHAGA BOOK's specification.

Specifically, the inner side of the cap 301 forms a cavity for mounting a structure such as a circuit board (in practical implementation, the structure such as the circuit board may not be mounted, and only the protection function is achieved). Specifically, the middle column 306 is fixed in the center of the cavity, the metal sheet 201 is disposed around the middle column, the circuit board 303 is fixed at the bottom of the cavity, and the above structures are defined in ZHAGA BOOK and 18 specifications.

Specifically, the metal sheet 201 is electrically connected to the circuit board 303, and the middle post 306 includes an electrical connection portion 305 at an end portion and a structural portion 304 at a root portion, where the electrical connection portion 305 is electrically connected to the circuit board 303. Specifically, a major variation of the protective cap of the present embodiment is that the structure of the center post 306 is adjusted.

Specifically, the wire diameter of the structural portion 304 in the embodiment of the present invention is consistent with the relevant dimension in ZHAGA BOOK' 18 specifications, and the electrical connection portion 305 is provided with an annular metal patch, and optionally, the wire diameter of the electrical connection portion 305 is smaller than the wire diameter of the structural portion 304.

Specifically, in ZHAGA BOOK, the function of the middle post 306 is mainly a positioning function, and in the embodiment of the present invention, the outer wall of the end of the middle post 306 is provided with the electric connection ring, so that the function of the original middle post 306 is not affected, and at the same time, the function of adding the external connection port of the protective cap is achieved, so that more connection modes between the circuit board and the LED driver can be realized.

Specifically, the function of the ZHAGA BOOK on the protective cap in the ZHAGA BOOK specification is mainly limited in the aspects of sensor and communication, and further, one of the current dimming modes of the LED is PWM dimming, and the brightness adjustment of the LED is realized through the duty ratio of a pulse signal; in general, the LED driving module controls the brightness of the LED by receiving the PWM signal, and when the PWM signal is not received, the LED driving module controls the brightness of the LED in a default state, so that the LED driving module can drive the LED to emit light with different brightness by accessing pulse signal generators with different duty ratios. In the embodiment of the present invention, in addition to the functions defined in ZHAGA BOOK ' 18 specification on the circuit board in the protective cap, on one hand, since the definition of one of the metal sheets 201 in ZHAGA BOOK's specification is power supply, a circuit structure or a component meeting the power supply requirement can be arbitrarily set on the circuit board, and then an additional definition port (different from the definition port specified in ZHAGA BOOK's specification) is implemented at the electrical connection portion on the intermediate column through the embodiment of the present invention for signal output.

Specifically, in the embodiment of the present invention, a brightness control module is further disposed on the circuit board 303, and the brightness control module is electrically connected to the electrical connection portion 305. Specifically, when the brightness control module is an LED driving module for PWM dimming, the brightness control module may be a PWM signal generating circuit with a preset duty cycle. If the brightness control module is for the constant current dimming LED driving module, optionally, firstly, a standard voltage of the power supply terminal is used as a reference, then a resistor with a preset resistance value is connected to the rear of the power supply terminal, and then the rear of the resistor is connected to the electric connection part 305, at this time, the current of the branch where the electric connection part 305 is located is changed; the LED driving module is used for driving the LEDs correspondingly by acquiring the current change condition.

It should be noted that, the protection cap (substantially, the circuit structure on the circuit board in the protection cap) and the LED driving module are set up in a matching way, and because the ZHAGA standard requires corresponding structural specifications for each main module, in substantial implementation, the circuit structure of the protection cap and the LED driving module are set up in a matching way, if a protection cap is mounted on a non-corresponding lamp, the protection cap (circuit structure of the protection cap) will not act, and in particular, the judging structure is the circuit design of the LED driving module.

Further, the protective cap according to the embodiment of the invention further comprises a gasket 302, and the gasket 302 is closely arranged on the root of the inner wall of the protective cap 301. On the one hand, referring to the protection cap of the prior structure shown in fig. 3 of the drawings, the connection structure of the protection cap and the socket body is realized by the buckle 202 on the side wall, and the contact surface of the protection cap and the socket body is difficult to ensure complete fitting because the protection cap and the socket body are generally made of hard plastics, so that the protection requirement of the protection cap and the socket body structure under the prior specification is difficult to meet with respect to the waterproof performance of the protection cap and the socket body; therefore, the gasket 302 is arranged on the inner wall of the protective cap, so that the waterproof performance of the protective cap after being matched with the socket body is improved; meanwhile, the gasket 302 has certain flexibility, and cannot interfere with the socket body in the conventional ZHAGA BOOK standard to prevent the combination installation of the protective cap and the socket body.

Further, the gasket 302 includes a hard core and a soft surface material that is wrapped around the hard core. Specifically, the socket body described later in this embodiment needs to be driven by the gasket, and in order to ensure the driving effect of the gasket on the trigger ring of the socket body, in the embodiment of the present invention, a hard core is disposed inside the gasket 302, so as to meet the requirements of position interference and sufficient driving force generation.

In summary, the embodiment of the invention provides a protective cap conforming to ZHAGA structural specifications, and under the precondition that the structural interchangeability of the protective cap is not affected, more connecting terminals can be provided on the protective cap for the electric connection of a circuit board by arranging the electric connection part on the middle post, so that the functions of the circuit structure on the circuit board can be expanded, and the protective cap has good practicability; through setting up luminance control module on the circuit board, can carry out luminance adjustment to lamps and lanterns through changing different protective cap, have good convenience of use.

Correspondingly, the embodiment of the invention also provides a socket body which can be used for installing the protective cap conforming to the ZHAGA structural standard, and particularly, the condition that the protective cap conforming to the ZHAGA structural standard can be installed is defined herein, that the socket body meets ZHAGA BOOK specifications on the connection structure of the protective cap with the ZHAGA structural standard.

Specifically, a fixing groove 403 is disposed at the axis of the socket body, and slots 410 are formed around the fixing groove 403, where the fixing groove 403 and the slots 410 are set to conform to ZHAGA BOOK' 18 specifications.

Specifically, on the basis of the existing ZHAGA BOOK standard socket body structure, the socket body of the embodiment of the invention further comprises a trigger component;

the trigger assembly comprises a trigger ring 401, a reset elastic piece 402, a trigger elastic piece 404, a lever type elastic piece 405 and an extending elastic piece 406.

The trigger ring 401 is coaxially embedded and arranged on the top surface of the socket body, the reset elastic piece 402 is arranged inside the socket body, and the bottom of the trigger ring 401 is in contact with the reset elastic piece which is kept in a compressed state; the trigger ring 491 has a trigger groove on its inner sidewall. Specifically, under the effect of the reset elastic piece 402, the trigger ring 401 is jacked up to be level with the top surface of the socket body (the corresponding protruding structure is arranged on the side wall of the trigger ring 401 to prevent the trigger ring 401 from being separated from the socket body), in the appearance, the socket body meets the ZHAGA BOOK standard appearance requirement in the default state of the trigger ring 401, and the trigger ring 401 cannot influence the appearance structure of the socket body.

The lever type elastic element comprises a torsion spring 405, and specifically, a fixed shaft is arranged inside the socket body for fixing the interior of the torsion spring 405, and a first wire tail and a second wire tail which are arranged in different directions are arranged outside the torsion spring 405.

Specifically, a first end of the reset elastic member 404 contacts with the inner wall of the trigger ring 401, and a second end of the reset elastic member 404 contacts with the first wire tail; the first end of the extending elastic piece 406 contacts with the second wire tail, and the second end of the extending elastic piece 406 faces into the fixing groove.

Specifically, the movement principle of the trigger assembly is that, in the default state of the trigger ring 401, the non-trigger groove position of the inner side wall of the trigger ring 401 contacts with the trigger spring 404, the reset of the torsion spring 405 needs to twist in the counterclockwise direction in the illustrated direction, and the trigger spring 404 prevents the torsion spring 405 from resetting, so that the positions of the first wire tail and the second wire tail on the torsion spring 405 are limited at the position shown in fig. 4, and at this time, since the second wire tail is far away from one side of the fixing groove 403, the second end of the protruding spring 410 can retract from the fixing groove 403, so that the extending of the middle post of the protective cap with a normal structure is not affected.

The trigger ring 401 is in a pressed state, the trigger ring 401 moves downward, a trigger groove on the inner side wall of the trigger ring 401 contacts with the trigger spring 404, the trigger spring 404 moves toward the trigger groove under the reset force of the torsion spring 405, and correspondingly, the second wire tail drives the extending spring to extend into the fixing groove 403.

Specifically, in order to ensure that the reset elastic member 404 and the socket body extending out of the elastic sheet 406 are provided with a first sliding groove, the reset elastic member is matched in the first sliding groove; and/or a second chute is arranged in the socket body, and the extending elastic sheet is matched in the second chute. Specifically, the forming structures of the first chute and the second chute in the embodiment of the invention are formed by arranging a plurality of limiting blocks.

Further, the triggering assembly further includes a connection wire 412, a first end of the connection wire is electrically connected to the protruding spring piece 406, and a second end of the connection wire is led out from the bottom of the socket body.

Furthermore, because the socket body is provided with four jacks (uniformly arranged along the periphery of the fixed groove) corresponding to the four metal sheets of the protective cap, in order to avoid position interference, the trigger assembly has a structure except the trigger ring, and the setting position of the trigger assembly is positioned between any two jacks; accordingly, in a specific implementation, in view of practical size constraints, up to four sets of trigger assemblies (sharing a trigger ring) may be provided; correspondingly, the extending elastic sheets in different trigger components are respectively arranged at different heights so as to be matched with corresponding electric connection parts on the protective cap. Correspondingly, the trigger ring has a certain difference in the setting positions of the trigger grooves corresponding to different trigger components, and the trigger ring is designed according to actual conditions in specific implementation.

Accordingly, since at least two metal sheets of the four metal sheets are used for transmitting differential signals, and accordingly, in order to avoid signal interference within a small-scale distance, in the embodiment of the present invention, the extended elastic sheet 406 is wrapped based on an electromagnetic isolation layer, it is to be noted that the second end of the extended elastic sheet 406 needs to be exposed; and/or an electromagnetic isolation layer 411 is provided on the inner wall of the fixing groove 403.

Further, the first end of the triggering spring 404 is curved into an arc shape, and the opening direction of the arc faces to one side of the fixing slot, so that the triggering spring 404 can conveniently enter and exit the triggering groove; and/or the second end of the extending elastic piece 406 is curved into an arc shape, and the opening direction of the arc shape faces to one side of the trigger ring, so that the extending elastic piece 406 is driven by the center column in the fixing groove to exit from the fixing groove.

The socket body of the embodiment of the invention has two implementation cases, and aiming at the protective cap which completely accords with ZHAGA BOOK standard (integral structure), as the trigger ring is not triggered, the extending elastic sheet 406 can retract to exit the fixed groove, the middle column of the protective cap can be matched in the fixed groove, and the trigger component does not influence the insertion of the protective cap; when a protective cap having an electrical connection portion and a washer (i.e., the protective cap according to the embodiment of the present invention) is mounted to the socket body, the washer presses the trigger ring 401 so that the protruding spring piece 406 can protrude into the fixing groove and fit on the corresponding electrical connection portion, which is in communication with the spring piece 406.

Correspondingly, the embodiment of the invention provides a lamp, which comprises the socket body.

The socket body and the lamp which conform to ZHAGA structural standards provided by the embodiment of the invention are described in detail, and specific examples are applied to illustrate the principle and the implementation of the invention, and the description of the above embodiments is only used for helping to understand the method and the core idea of the invention; meanwhile, as those skilled in the art will have variations in the specific embodiments and application scope in accordance with the ideas of the present invention, the present description should not be construed as limiting the present invention in view of the above.
