The connecting portion 14 is provided with a holding and positioning portion 141. The mounting assembly 30 includes a mounting plate 32 and an elastic clamping member 34, where the mounting plate 32 is inserted into the connecting portion 14 and is in clamping fit connection with the clamping positioning portion 141. When the elastic clamping member 34 is connected to the mounting plate 32 and the limiting portion 121 is limited on the target plate 300, the elastic clamping member 34 is used for respectively supporting the limiting portion 121 on two sides of the target plate 300.

It should be understood that "an element abuts against another element" in this specification, it should be understood that the two may abut directly or indirectly (e.g., when there is an intervening element therebetween), e.g., the other element is mounted on the intervening element, and the element may abut against the intervening element, thereby "abutting against the other element".

During installation, the down lamp installation structure 100 is aligned to the installation hole on the target plate body 300, during installation, the abutting part 343 and the torsion spring 341 are twisted firstly, the whole outer diameter of the down lamp shell 100 is smaller than the aperture of the installation hole, then the down lamp shell is placed into the installation hole, the abutting part 343 enters through the installation hole and is positioned at the other side of the target plate body 300, then the external force is removed, and the whole down lamp shell 100 is pushed into the installation hole until the limiting part 121 abuts against the target plate body 300. The elastic clamping piece 34 is abutted against one side of the target plate 300 under the action of elastic potential energy, so that the limiting part 121 outside the mounting hole of the target plate 300 is abutted against the other side surface of the target plate 300. The elastic clamping member 34 and the limiting portion 121 are respectively abutted against two sides of the target plate 300, so that the down lamp mounting structure 100 is mounted together. The elastic clamping piece 34 is arranged on the down lamp shell 10 through the mounting plate 32, the mounting plate 32 bears the concentrated stress generated by the elastic clamping piece 34, the mounting plate 32 is inserted into the connecting part 14, the contact area between the mounting plate 32 and the down lamp shell 10 is large, and the concentrated stress borne by the down lamp shell 10 is reduced. The installation plate 32 reduces the requirement of the down lamp installation structure 100 on the strength of the down lamp housing 10, and various materials with small strength can be adopted to manufacture the down lamp housing 10 or the down lamp housing 10 can be manufactured to be thinner, so that the production and manufacturing cost is reduced.

Referring to fig. 1 and 3, in the present embodiment, the lamp housing 10 may include a housing 16, a panel 12 and a connecting portion 14. The connecting portion 14 is connected to one side of the panel 12, and the housing 16 is connected to one side of the panel 12 near the connecting portion 14 and covers the connecting portion 14. The housing 16, the connecting portion 14, and the panel 12 together define the accommodating chamber 18, and the opening 181 is provided in the panel 12.

The panel 12 is substantially annular plate-like having a predetermined axial direction O, which in this embodiment is substantially the same direction as the width direction of the panel 12. The panel 12 includes a body 123 and the above-described stopper 121. The opening 181 is formed in the body 123, and the opening 181 penetrates through the body 123 along the axial direction O to communicate the accommodating cavity 18 with the outside, so as to facilitate the installation of the light emitting module 201 and the emergence of light. The limiting portion 121 is connected to the outer periphery of the body 123 along the circumferential direction of the body 123. As an example, the limiting portion 121 may be integrally connected with the body 123, and both side surfaces of the limiting portion 121 are substantially smoothly connected with the body 123. The limiting portion 121 protrudes substantially radially with respect to the side wall of the housing 16 to form a flange structure, the outer diameter of the housing 16 is smaller than the aperture of the mounting hole on the target board 300, and the outer diameter of the limiting portion 121 is larger than the aperture of the mounting hole. When the down lamp is installed, the shell 16 stretches into the installation hole on the target plate body 300, and the limiting part 121 is clamped on the surface of one side, far away from the shell 16, of the target plate body 300, so that the effect of limiting the down lamp installation structure 100 is achieved.

In the description of the present application, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "inner," and the like indicate orientation or positional relationships based on those shown in the drawings, and are merely used for simplifying the description of the present application, rather than indicating or implying that the apparatus or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application.

In the above-mentioned "the limiting portion 121 is clamped to the target plate 300", the limiting portion 121 and the target plate 300 may be in direct contact with each other or in indirect contact with each other, for example, there is a centering element therebetween. In the present embodiment, a cushion ring 50 may be provided between the stopper 121 and the target plate 300. The buffer gasket 50 may be fixedly disposed at a side of the limiting part 121 facing the housing 16, and the buffer gasket 50 surrounds the housing 16. When the down lamp mounting structure 100 is mounted, the limiting part 121 indirectly abuts against the target plate 300 through the buffer gasket 50 under the action of elastic potential energy of the elastic clamping piece 34. The cushion ring 50 can reduce collision damage between the stopper 121 and the target plate 300.

In this embodiment, the connection portion 14 may be integrally formed on one side of the panel 12 and protrude with respect to the surface of the one side of the panel 12, and the protruding direction of the connection portion 14 may be approximately along the axial direction O, for example, the protruding direction may be approximately perpendicular to the panel 12. Referring to fig. 2, the connecting portion 14 is provided with a slot 147, and the slot 147 penetrates through an end of the connecting portion 14 away from the panel 12 along the axial direction O, and the mounting plate 32 is inserted into the slot 147. Specifically, the connecting portion 14 may include a first abutting surface 143 and a second abutting surface 145 disposed at opposite intervals, where the first abutting surface 143 and the second abutting surface 145 jointly define the slot 147, and the clamping positioning portion 141 is disposed on the first abutting surface 143. When the mounting plate 32 is inserted into the slot 147, the mounting plate 32 is in clamping fit connection with the clamping and positioning portion 141.

In the present specification, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless explicitly defined otherwise.

The housing 16 includes a peripheral wall 161 and a top wall 163, the peripheral wall 161 being connected to the top wall 163 in the circumferential direction of the top wall 163, the peripheral wall 161 being substantially cylindrical with both ends penetrating, the peripheral wall 161 being coaxially connected to the panel 12 and surrounding the connecting portion 14. The top wall 163 is an end of the peripheral wall 161 remote from the panel 12 and approximately closes an end of the peripheral wall 161 to define the receiving cavity 18 with the peripheral wall 161 and the panel 12. The top wall 163 may be provided with a wire passing through hole penetrating the top wall 163 in the axial direction O, so that the receiving chamber 18 communicates with the outside, so that a power supply cable electrically connected to the light emitting unit passes therethrough.

The top wall 163 may also be provided with a relief opening 1632, the relief opening 1632 extending through the top wall 163 in the axial direction O. One end of the connecting portion 14 remote from the panel 12 is received in the relief 1632, such that the slot 147 communicates with the exterior of the housing 16. The mounting plate 32 is inserted through the relief 1632 and into the slot 147. The yielding port 1632 can be arranged to position the outer shell 16 through the connecting part 14, ensure the relative position relationship of the two, support one end of the connecting part 15 far away from the panel 12 and strengthen the strength of the connecting part 14.

In some embodiments, the connection portion 14 may not be disposed on the panel 12, and the connection portion 14 may be disposed on the housing 16, for example, the connection portion 14 may be a slot formed on the top wall 163 or a connection block provided with a slot, and the connection portion 14 may also be a slot formed on the peripheral wall 161 or a connection block provided with a slot.

In this embodiment, the mounting plate 32 has a first end 321 and a second end 323 opposite to each other, the first end 321 is located in the slot 147 and is in locking engagement with the locking positioning portion 141, and the second end 323 protrudes relative to the top wall 163 and is connected to the elastic locking member 34. The mounting plate 32 is used for mounting the elastic clamping member 34 to the cartridge lamp housing 10, and for increasing the area of the cartridge lamp housing 10 that is subjected to torsion force exerted by elastic potential energy of the elastic clamping member 34.

The mounting plate 32 has a substantially rectangular plate shape and extends substantially in the axial direction O when mounted on the down lamp housing 10. The specific clamping matching relationship between the mounting plate 32 and the clamping positioning portion 141 is not limited in this specification, and the mounting plate 32 may be clamped and limited to the clamping positioning portion 141, for example, the clamping positioning portion 141 may be formed in a groove, a hole, or other structures of the first abutting surface 143, and the second end 323 of the mounting plate 32 or a protruding structure of the mounting plate 32 may be clamped and positioned in the clamping positioning portion 141. The holding and positioning portion 141 may be held and limited by the mounting plate 32, and in this embodiment, a limiting groove 3212 is provided at the first end 321 of the mounting plate 32.

Referring to fig. 2, the clamping and positioning portion 141 is a protruding structure connected to the first supporting surface 143 (for example, integrally formed on the first supporting surface 143), the clamping and positioning portion 141 protrudes relative to the first supporting surface 143, and the clamping and positioning portion 141 is embedded in the limiting groove 3212. In this embodiment, in order to improve the mounting efficiency of the mounting plate 32 on the down lamp housing 10, the holding and positioning portion 141 may be made of an elastic material, and the holding and positioning portion 141 has a guiding inclined surface 1412, and the guiding inclined surface 1412 is inclined with respect to the direction in which the mounting plate 32 is inserted into the slot 147. Specifically, the guiding inclined surface 1412 has a connection end 1414 and a limiting end 1416, the connection end 1414 is connected to the first supporting surface 143, the limiting end 1416 is spaced from the first supporting surface 143, and a distance between the connection end 1414 and the bottom of the slot 147 is greater than a distance between the limiting end 1416 and the bottom of the slot 147. The mounting plate 32 is inserted into the slot 147, and the mounting plate 32 first abuts against the guide slope 1412, and continues to move toward the bottom of the slot 147 under the guide of the guide slope 1412. In the moving process, the clamping and positioning part 141 is elastically deformed under the extrusion of the mounting plate 32 until the mounting plate 32 moves to the position where the limiting groove 3212 is opposite to the clamping and positioning part 141, the clamping and positioning part 141 releases elastic potential energy to restore the original shape, so that the limiting end 1416 is embedded in the limiting groove 3212. The holding and positioning portion 141 prevents the mounting plate 32 from coming off the stopper groove 3212, so that the mounting assembly 30 can be easily mounted on the down lamp mounting structure 100.

Referring to fig. 4, in the present embodiment, the elastic retaining member 34 may include a torsion spring 341 and a supporting portion 343, the torsion spring 341 is disposed at the second end 323, and the supporting portion 343 is connected to the torsion spring 341. The torsion spring 341 is in a state with elastic potential energy, so as to drive the abutting portion 343 to cooperate with the limiting portion 121 to jointly abut against two sides of the target plate 300 (as shown in fig. 1).

Referring to fig. 4 and 5, in order to facilitate the installation of the torsion spring 341, the second end 323 is provided with an installation opening 3232 for receiving the torsion spring 341. The mounting hole 3232 penetrates the mounting plate 32 in the thickness direction of the mounting plate 32, and the mounting hole 3232 penetrates the second end 323 in the axial direction O (shown in fig. 3). The side wall of the mounting port 3232 is provided with a mounting projection 3234, and the mounting projection 3234 projects with respect to the side wall of the mounting port 3232. The torsion spring 341 is accommodated in the mounting opening 3232 and is sleeved on the mounting protrusion 3234. Therefore, the torsion spring 341 is limited to the mounting opening 3232 by the mounting protrusion 3234, and the mounting protrusion 3234 is inserted into the torsion spring 341 from the end of the torsion spring 341. In the present embodiment, the number of the mounting protrusions 3234 is two, the two mounting protrusions 3234 are respectively provided on opposite side walls of the mounting opening 3232, and the two mounting protrusions 3234 are respectively inserted into the torsion spring 341 from both ends of the torsion spring 341. In this embodiment, the abutting portion 343 is disposed obliquely to the plane of the mounting plate 32, and one end of the abutting portion 343 is connected to the torsion spring 341, and the other end is disposed at a distance from the mounting plate 32, and is configured to abut against the target plate 300 when the limiting portion 121 is limited to one side of the target plate 300 (as shown in fig. 1). The abutting portion 343 may be integrally formed with the torsion spring 341, or may be welded to or engaged with the torsion spring 341. The abutting portion 343 has a substantially rectangular frame shape, and the abutting portion 343 extends in a direction perpendicular to the center axis of the spiral deformation portion 3416. Referring to fig. 1 and fig. 6, an angle a is formed between the extending direction of the abutting portion 343 and the plane of the mounting plate 32, the angle a is smaller than 90 degrees, and the opening direction of the angle a faces the panel 12. When the abutting portion 343 is not abutted against the target plate 300, the included angle a may be less than or equal to 45 degrees, so that the elastic clamping member 34 can be ensured to have enough elastic potential energy to abut against the target plate 300.

In the present embodiment, the abutting portion 343 has a gripping position abutting against the target plate 300 (shown in fig. 1) and a release position separated from the target plate 300. The abutment 343 can be twisted relative to the mounting plate 32 by the torsion spring 341 to switch between the clamping position and the release position. During installation, the abutting part 343 and the torsion spring 341 are twisted first, so that the overall outer diameter of the down lamp housing 100 is smaller than the aperture of the mounting hole, then the down lamp housing is placed in the mounting hole, the abutting part 343 enters through the mounting hole and is positioned at the other side of the target plate 300, then the external force is removed, and the whole down lamp housing 100 is pushed into the mounting hole until the limiting part 121 abuts against the target plate 300. Due to the elastic force of the torsion spring 341, the abutting portion 343 receives a force towards the mounting plate 32, so that the abutting portion 343 can abut against the target plate 300, so that the mounting assembly 30 and the target plate 300 are relatively fixed, and the down lamp mounting structure 100 and the target plate 300 are relatively fixed.

Referring to fig. 1 and 2 again, when the abutting portion 343 abuts against the target board 300, the mounting plate 32 is close to the first abutting surface 143 by the reaction force of the abutting portion 343. Specifically, a contact surface 325 is provided on a side of the mounting plate 32 facing the first abutting surface 143, and when the abutting portion 343 abuts against the target plate 300, the contact surface 325 abuts against the first abutting surface 143. The first abutment surface 143 and the contact surface 325 increase the contact area of the elastic latching member 34 with the down lamp housing 10, and increase the stress area of the down lamp housing 10, thereby reducing the concentrated stress of the down lamp housing 10. During installation, the abutting portion 343 is reversely rotated (i.e. one end of the abutting portion 343, which is away from the torsion spring 341, is rotated away from the mounting plate 32), and at this time, the opposite surface of the mounting plate 32 and the contact surface 325 abuts against the second abutting surface 145, which also achieves the effect of reducing the concentrated stress of the down lamp housing 10.

In this embodiment, the elastic retaining member 34 may further include a protective sleeve 345, where the protective sleeve 345 is sleeved on an end of the supporting portion 343 away from the torsion spring 341. The protective sleeve 345 is used for increasing the friction force and the contact area between the abutting portion 343 and the target plate 300, and improving the mounting stability of the down lamp mounting structure 100. The specific material of the protective sleeve 345 is not limited in this specification, and the protective sleeve 345 may be made of silica gel, rubber, resin, etc. The protective sleeve 345 may also be provided with a slot for assisting in positioning during assembly.

One end that protective sheath 345 kept away from torsional spring 341 is crooked towards mounting panel 32 sets up, and the one end inner buckle setting of protective sheath 345 butt target plate body 300 has improved the frictional force between protective sheath 345 and the target plate body 300, makes down lamp mounting structure 100's installation more stable.

In the present embodiment, the number of the mounting assemblies 30 may be plural, and the plural mounting assemblies 30 are sequentially arranged in the circumferential direction of the top wall 163. In the present embodiment, the number of the mounting assemblies 30 is two, the two mounting assemblies 30 are respectively disposed on two sides of the down lamp housing 10, and the two mounting assemblies 30 further improve the stability of the down lamp mounting structure 100 mounted on the target board 300 (as shown in fig. 1). Correspondingly, two connecting parts 14 are also arranged, and the two connecting parts 14 are respectively arranged at two sides of the panel 12. The number of the relief ports 1632 of the top wall 163 is also two, and the connection portion 14, the relief ports 1632, and the mounting assembly 30 are disposed in a uniform and corresponding manner.

When the down lamp mounting structure 100 is assembled, the mounting plate 32 is inserted into the slot 147, and the clamping and positioning part 141 is limited in the limiting groove 3212, so that the mounting plate 32 is prevented from being separated from the limiting groove 3212. During installation, the abutting part 343 and the torsion spring 341 are twisted first, so that the overall outer diameter of the down lamp housing 100 is smaller than the aperture of the mounting hole, then the down lamp housing is placed in the mounting hole, the abutting part 343 enters through the mounting hole and is positioned at the other side of the target plate 300, then the external force is removed, and the whole down lamp housing 100 is pushed into the mounting hole until the limiting part 121 abuts against the target plate 300. Due to the elastic force of the torsion spring 341, the abutting portion 343 receives a force towards the mounting plate 32, so that the abutting portion 343 can abut against the target plate 300, so that the mounting assembly 30 and the target plate 300 are relatively fixed, and the down lamp mounting structure 100 and the target plate 300 are relatively fixed. The arrangement of the mounting plate 32 increases the contact area between the elastic clamping piece 34 and the down lamp housing 10, and reduces the concentrated stress of the down lamp housing 10, thereby reducing the requirement of the down lamp mounting structure 100 on the strength of the down lamp housing 10, enabling the down lamp housing 10 to be made of various materials with small strength, or enabling the down lamp housing 10 to be made thinner, and reducing the production cost.
