The embodiment of the present invention provides a knob structure and a lamp.

Referring to fig. 1 to 16, an embodiment of the present invention provides a knob structure to protect a rotary switch 200 included in the knob structure. Specifically, the knob structure includes a protection structure, a knob switch 200, a knob 300, and a connection structure. The protection structure forms a protection cavity 100, the knob switch 200 is disposed inside the protection cavity 100, the knob 300 is disposed outside the protection cavity 100, and the knob 300 is connected to the knob switch 200 in a transmission manner to drive the knob switch 200 to operate. The protection structure forms the protection cavity 100 as a relatively closed hollow cavity, so that the rotary switch 200 located in the protection cavity 100 is not damaged by impact force from multiple directions, and the specific shape of the protection cavity 100 in this embodiment may be one of a spherical cavity, a cylindrical cavity, or a box-shaped cavity, and other shapes of cavities. The knob 300 and the knob switch 200 may be of a type commonly used in the prior art, and corresponding connection structures may be adapted according to different types of the knob 300, and the knob 300 and the protection structure are connected through the connection structures and limit the relative translation between the two.

According to the above structure, the knob structure provided in the present embodiment is not damaged by the impact of the external force since the knob switch 200 is completely disposed in the protection cavity 100 after the impact of the external force. When the knob 300 in transmission connection with the knob switch 200 is used as a stressed part impacted by external force, because the connecting structure is arranged between the knob 300 and the protection structure, the connecting structure can limit the translation between the knob 300 and the protection structure while connecting the knob 300 and the protection structure, and because the knob 300 can not translate relative to the protection structure, the impact force borne by the knob 300 can not be transferred to the knob switch 200 in the protection cavity 100, the knob switch 200 is further ensured not to be damaged, through the arrangement of the structure, the knob switch 200 is well protected, the damage caused by the impact of the external force is avoided, and the service life of the knob switch 200 is greatly prolonged.

It can be understood that, the protection cavity 100 in this embodiment is used as a relatively closed cavity, and when the knob 300 located outside the protection cavity 100 is in transmission connection with the knob 300 located inside the protection cavity 100, a small gap that does not affect the protection effect of the knob switch 200 may be formed on the side wall of the protection cavity 100, for example, the knob 300 is in transmission connection with the knob switch 200 through a rotating shaft, a hole for the rotating shaft to pass through is formed on the side wall of the protection cavity 100, and after the rotating shaft is accommodated in the through hole, a small gap remains between the rotating shaft and the through hole, and since in this embodiment, the small gap does not affect the protection effect of the knob switch 200 to be protected in this embodiment, the small gap formed by other transmission structures that can achieve transmission connection between the knob 300 and the knob switch 200 will not be described.

Referring to fig. 1 to 3, in some embodiments, for the purpose of easy installation and disassembly for maintenance, the protection structure is preferably configured to include a first sidewall 101 and a stopper 102, wherein the first sidewall 101 is an annular sidewall having one side opened and serves as a sidewall of the protection cavity 100. The stopper 102 has a first surface 121 adapted to the shape of the opening at the side of the first sidewall 101 and serves as a top wall of the protection chamber 100. The cross-sectional shape of the annular sidewall of the first sidewall 101 in this embodiment may be one of circular, rectangular or other polygonal shapes, and the shape of the first surface 121 is configured corresponding to the first sidewall 101 to form a relatively closed protection cavity 100.

According to the above structure, when the knob switch 200 inside the protection cavity 100 needs to be repaired, the stopper 102 can be removed and the knob switch 200 can be repaired, which has flexible and convenient effects.

It is understood that the first sidewall 101 described in the present embodiment is intended to surround the rotary switch 200 in a certain direction and form a protection, so that the cross-sectional shape of the first sidewall 101 for achieving the purpose can be applied to the present rotary switch structure; in addition, in the present embodiment, only one side of the first sidewall 101 is provided with an opening and is closed by the stopper 102, and in other embodiments, the first sidewall 101 may also have two or more sides of the opening and is closed by a corresponding number of stoppers 102. In some specific application scenarios, for example, when the knob structure provided by the present invention is applied to some electronic devices, because the electronic device generally has a relatively closed housing, the housing of the electronic device can be further communicated with the protection cavity 100 of the knob structure, so that the protection cavity 100 and the interior space of the housing form an integrated space, or the protection cavity 100 is integrally formed in the device housing, in this application scenario, the knob switch 200 can be further disposed inside the housing of the electronic device, and is in transmission connection with the knob 300 through the opening on one side formed by the first side wall 101.

As a further preference, the end of the blocking member 102 facing away from the first surface 121 in the present embodiment has a width larger than the opening formed by the first sidewall 101 and is used for limiting the blocking member 102 from completely entering the protection cavity 100, so that after the protection cavity 100 is impacted by an external force, the blocking member 102 falls into the protection cavity 100 and loses the protection of the rotary switch 200 or the blocking member 102 falling into the protection cavity 100 itself impacts the rotary switch 200. Specifically, the end of the stopper 102 facing away from the first surface 121 may be configured as any structure with a width larger than the opening on the first side wall 101, such as a linear, circular or rectangular structure, so as to ensure that the stopper 102 cannot enter the protection cavity 100.

In this embodiment, the transmission connection between the knob 300 and the knob switch 200 may be disposed on the first sidewall 101 or disposed on the stopper 102, and preferably, the present embodiment takes the form of the transmission connection between the knob 300 and the knob switch 200 through the stopper 102. Specifically, the stopper 102 has a first surface 121 larger than an opening on one side of the first sidewall 101, the stopper 102 is completely located outside the protection cavity 100 and can rotate relative to the first sidewall 101 while closing the opening, the shape of the first surface 121 can be one of circular, rectangular or other polygonal shapes, the knob 300 and the knob switch 200 are respectively in transmission connection with the stopper 102, and the rotation of the knob 300 drives the stopper 102 to rotate and further drives the knob switch 200 to rotate.

According to the above structure, the purpose of using the stopper 102 as a part of the transmission connection between the knob 300 and the knob switch 200 can be achieved, and the technical effects of simplifying the transmission connection structure and facilitating the disassembly and maintenance can be achieved.

It can be understood that, in the present embodiment, the blocking member 102 is rotatable relative to the first sidewall 101, and there are various implementations, one of which is that the first sidewall 101 is configured to be circular, one side of the first sidewall 101 is opened to be a circular opening, the first surface 121 is also circular to be adapted to the opening of the first sidewall 101, so as to be rotatable relative to the first sidewall 101 at the opening of the first sidewall 101, and the blocking member 102 is configured to pass through an end facing away from the first surface 121 to avoid falling into the protection cavity 100; it is also possible that the first surface 121 has a smaller size than the opening of the first sidewall 101, and the end of the stopper 102 facing away from the first surface 121 has a larger shape than the opening of the first sidewall 101 and can completely cover the opening, and that the relative rotation of the stopper 102 with respect to the first sidewall 101 can be achieved. In still other embodiments, the stop 102 can have other rotatable forms. It is understood that other shapes of the stopper 102 having the same effect are considered to be within the scope of the present invention and are not described in detail.

Referring to fig. 4 to 7, generally, the rotary switch 200 has a rotary shaft 201. In order to eliminate the non-concentric error between the stopper 102 and the knob shaft 201 when the stopper 102 is provided as a part of the driving connection between the knob 300 and the knob switch 200, in some embodiments, a buffer structure is further provided between the stopper 102 and the knob shaft 201.

Specifically, the buffering structure includes a first buffering member 400 and a second buffering member 500. The first buffer member 400 is a protrusion formed on the first surface 121 and facing the knob rotating shaft 201, the second buffer member 500 is connected to the knob rotating shaft 201 and has a cross-shaped cross-sectional shape along the axial direction of the knob rotating shaft 201, and four adjacent included angle spaces 501 are formed in the axial direction of the knob rotating shaft 201; when installed, the first cushion 400 extends into the angle space 501 and is used to abut against the second cushion 500.

According to the above structure, when the stopping member 102 is in transmission connection with the knob switch 200, the protrusion on the first surface 121 of the stopping member 102 only needs to be inserted into the four included angle spaces 501 formed by the second buffer member 500, and does not need to be absolutely and accurately corresponding to the knob rotating shaft 201. It is worth noting that the size of the four included angle spaces 501 can be flexibly set according to the protruding size of the first buffer member 400, the included angle space 501 cannot enter the included angle space 501 due to the undersize of the included angle spaces 501, and the first buffer member 400 can be abutted to the second buffer member 500 after rotating for a certain distance due to the oversize of the included angle spaces 501, so that uncomfortable interruption hand feeling can be generated. When the transmission structure works, the blocking piece 102 rotates to drive the first buffering piece 400 to rotate, and further drives the second buffering piece 500 to rotate, and the second buffering piece 500 is connected to the knob rotating shaft 201, so that the effect that the blocking piece 102 drives the knob rotating shaft 201 to rotate can be achieved, and the non-concentric error between the blocking piece 102 and the knob rotating shaft 201 can be eliminated.

It is understood that the protrusion formed on the first surface 121 in the present embodiment may be provided with one or more. Similarly, one or more angular spaces 501 formed by the second dampener 500 attached to the knob structure can be provided. As a further preference, the first cushion 400 in this embodiment is formed by four protrusions formed on the first surface 121 and corresponds to the four angle spaces 501 formed by the second cushion 500. In the embodiment where the first buffer 400 is only provided as a protrusion, the protrusion cannot be a rotation center formed on the first surface 121 when the protrusion is formed on the first surface 121, so as to avoid that when the stopper 102 rotates, the first buffer 400 performs a rotation motion with a radius of zero relative to the first surface 121, so that the stopper 102 cannot drive the second buffer 500 and the knob structure to rotate, thereby disabling the transmission connection between the knob 300 and the knob switch 200.

In addition, the shape of the first buffer 400 in this embodiment is not limited, and may be a circular, rectangular, or other shaped protrusion; the first buffer member 400 and the second buffer member 500 may be formed integrally with the stopper 102 and the knob shaft 201, or may be formed as an independent structure, wherein the first buffer member 400 may be fixed to the first surface 121 through some common connection methods such as gluing or welding, the second buffer member 500 may be provided with a recess adapted to the knob shaft 201 and sleeved on the knob shaft 201 through the recess, and the first buffer member 400 and the second buffer member 500 may be formed as an independent structure.

Referring to fig. 8 to 9, in the above embodiment with the buffering structure, in order to eliminate the non-concentric error between the blocking member 102 and the knob rotating shaft 201, after the first buffering member 400 extends into the included angle space 501 formed by the second buffering member 500, a gap is left between the first buffering member 400 and the second buffering member 500, thereby causing a weak interruption feeling between the blocking member 102 and the knob rotating shaft 201 in the forward and reverse rotation processes. In some embodiments, in order to maintain the continuous feel of the knob structure in rotation, a buffer medium 600 is further disposed between the first buffer 400 and the second buffer 500. Specifically, the buffering medium 600 has elasticity and is filled in the gap between the first buffering member 400 and the second buffering member 500, and the buffering medium 600 may specifically be made of, for example, silicone, rubber, or other materials having elasticity.

According to the above configuration, the gap between the first cushion member 400 and the second cushion member 500 is filled with the cushion medium 600, and both the first cushion member 400 and the second cushion member 500 continuously contact the cushion medium 600. Therefore, the problem of non-concentric error between the knob rotating shaft 201 and the blocking piece 102 can be solved, and the continuity of the rotating hand feeling can be kept.

It can be understood that the buffering medium 600 in this embodiment may be formed independently, or may be disposed on the first buffer member 400 or the second buffer member 500 to form an integral structural member, and in the embodiment where the second buffer member 500 is provided with the four included angle spaces 501, the buffering medium 600 filled in the four included angle spaces 501 may be disposed as an integral structure, which has the technical effects of being convenient for replacement and being convenient for disassembly and assembly.

Referring to fig. 11 to 13, in some embodiments, the connection structure specifically includes a snap 700 and a ring-shaped second sidewall 301. The second side wall 301 is annularly arranged outside the first side wall 101 and is abutted against the first side wall 101; grooves are respectively arranged on the first side wall 101 and the second side wall 301, and the buckle 700 is used for being accommodated in the grooves of the first side wall 101 and the second side wall 301. In the connection state of the knob 300 and the protection structure, at least a portion of the clip 700 is accommodated in the slots formed on the first sidewall 101 and the second sidewall 301, that is, the height of the clip 700 should be at least greater than the depth of the grooves formed on the first sidewall 101 and the second sidewall 301.

According to the above structure, the annular second sidewall 301 is arranged around the outside of the first sidewall 101, the first sidewall 101 is a side wall of the protection structure for forming the protection cavity 100, and is also an annular structure, so that the first sidewall 101 and the second sidewall 301 form a sleeve-shaped structure, the movement of the first sidewall 101 in any direction diverging from the center to the annular sidewall is blocked by the second sidewall 301, and when the buckle 700 is not arranged, the first sidewall 101 can only be separated from the second sidewall 301 in the direction in which the annular sidewall extends; since the first sidewall 101 and the second sidewall 301 are further respectively provided with a slot, and at least a portion of the clip 700 is further accommodated in the slots provided on the first sidewall 101 and the second sidewall 301 in the connection state of the knob 300 and the protection structure, the relative movement of the first sidewall 101 and the second sidewall 301 in the extension direction of the annular sidewall thereof is also limited. Based on the above structure, the first sidewall 101 and the second sidewall 301 cannot be translated relatively in any direction. Further, the knob 300 and the protective structure are constrained by the coupling structure to produce relative translational movement in either direction.

It is understood that the annular second sidewall 301 is sleeved outside the annular first sidewall 101, and the annular cross-sectional shapes of the two are not particularly limited but preferably correspond, and if the first sidewall 101 is circular, the second sidewall 301 is preferably circular; the first side wall 101 is configured as a square, and the second side wall 301 is also preferably configured as a square, so that the first side wall 101 and the second side wall 301 can have better abutting effect and the connection structure has more integrity. Of course, in other embodiments, the first sidewall 101 may be an annular sidewall with a square cross section and inscribed in the second sidewall 301 with a circular cross section, and the effect of limiting the relative movement between the first sidewall 101 and the second sidewall 301 may also be achieved.

The specific shape of the clip 700 is not limited, and may be a circular, rectangular, or other structure with any shape, so that in the connection state of the knob 300 and the protection structure, at least a part of the clip 700 is accommodated in the slots provided on the first sidewall 101 and the second sidewall 301. Of course, the latch 700 may also be integrally formed on the first sidewall 101 or the second sidewall 301, and in such an embodiment, the latch 700 is actually a protrusion formed on the first sidewall 101 or the second sidewall 301 and received in a corresponding groove on the second sidewall 301 or the first sidewall 101. Furthermore, the connecting structure may also be that the first side wall 101, the second side wall 301 and the buckle 700 are all integrally formed structures, that is, the connecting structure and the protection structure are actually integrally formed, and the knob 300 is directly fixed to the protection structure by welding or gluing or other means. It should be noted that the connecting structure is only used to connect the knob 300 and the protection structure, and does not affect the normal operation of the knob 300. Of course, connecting the knob 300 with the protection structure through the connection structure has the technical effects of convenient installation and easy disassembly and maintenance.

In some embodiments, the knob 300 and the second sidewall 301 are specifically configured to be an integrally formed structure, the first sidewall 101 and the second sidewall 301 are configured to be a ring-shaped structure with a circular cross section, and the grooves disposed on the first sidewall 101 and the second sidewall 301 are also configured to extend in a circumferential direction. Therefore, although the first side wall 101 and the second side wall 301 cannot make relative translation, the second side wall 301 can still make relative rotation with respect to the first side wall 101.

According to the above structure, the second sidewall 301 can also be used as a part of the knob 300 in a knob structure provided by the present invention, further, a side opening of the second sidewall 301 can also extend toward the center of the second sidewall 301 to form a third sidewall 302, the third sidewall 302 and the second sidewall 301 together serve as the knob 300 described in the present embodiment, and the third sidewall 302 is used for being drivingly connected to the stopper 102 and driving the stopper 102 to rotate by the rotation of the second sidewall 301.

It is understood that, in the present embodiment, the third sidewall 302 extending from the second sidewall 301 closes an opening of the second sidewall 301 to form a concave cavity, and a portion of the protection cavity 100 formed by the first sidewall 101 and the stopper 102 is received in the concave cavity. According to the structure, not only the overall space occupation of the knob structure provided by the embodiment can be reduced, but also the knob structure composed of the third sidewall 302 and the second sidewall 301 can further protect the protection cavity 100 located inside the recessed cavity. Furthermore, the second side wall 301 is further provided with a texture for preventing slipping, so that the knob structure has a better use effect.

Referring to fig. 13, on the basis of the above-mentioned embodiment provided with the clip 700, the direction of the first sidewall 101 departing from the second sidewall 301 is defined as a first direction, the clip 700 in some embodiments is configured to have a first inclined slope 701 facing away from the first direction at the proximal end in the first direction, and the groove provided on the first sidewall 101 has a second inclined slope 111 facing the first direction and adapted to the first inclined slope 701; in other embodiments, the clip 700 may be further configured to have a third inclined slope 702 facing the first direction at the distal end in the first direction, and the groove disposed on the second sidewall 301 has a fourth inclined slope 311 facing away from the first direction and adapted to the third inclined slope 702.
