[0002] At present, some track lamps on the market basically use magnetic attraction or the deformation of plastic parts themselves to achieve the fixed installation between the lamp and the track. However, the above fixed installation methods are limited by factors such as the load-bearing capacity of magnetic parts or degaussing, and serious deformation of plastic parts under force, making the above fixed installation methods unstable and the load-bearing capacity limited.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0033] The embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0034] refer to Figures 1 to 9 The embodiment of the present application discloses a connection assembly 01, which is used to connect a lamp 02 and a track 03. In addition, it can also be used to connect two other objects, which is not specifically limited here. The disclosed connection assembly 01 includes a housing 10, a pressing member 20, a clamping member 30 and an elastic member 40.

[0035] The housing 10 is a basic component, which can provide an installation basis for components such as the pressing member 20, the clamping member 30, and the elastic member 40. In addition, the housing 10 can also be used to connect the lamp 02 to play a role in fixing and supporting the lamp 02. In some embodiments, such as Figure 1 , Figure 2 and Figure 6 shown, the housing 10 is provided with a communicating cavity M and a limiting hole 111. Among them, the cavity M can provide an accommodation space for the pressing member 20, and the limiting hole 111 can provide an accommodation space for the clamping member 30 and limit the clamping member 30; in addition, the limiting hole 111 communicates with the cavity M so that the pressing member 20 and the clamping member 30 can cooperate with each other.

[0036] The clamping member 30 is used to connect the connection assembly 01 to the track 03 to ensure the reliability of the connection between the connection assembly 01 and the track 03. Of course, the clamping member 30 can also be separated from the track 03 to facilitate the removal of the connection assembly 01. In some embodiments, such as Figure 5 shown, the clamping member 30 has a clamping portion 31 and a transmission portion 32. Among them, the clamping portion 31 and the transmission portion 32 can be fixedly connected, and of course, they can also be integrally provided.

[0037] The clamping portion 31 is movably disposed in the limiting hole 111, so that the clamping portion 31 can extend out of the cavity M through the limiting hole 111 and can also move in the limiting hole 111 to facilitate the switching of the clamping state and the unlocking state between the clamping portion 31 and the track 03. It should be noted here that based on the setting of the limiting hole 111, on the one hand, the clamping member 30 can be limited by the hole wall of the limiting hole 111 to prevent the clamping member 30 from moving randomly, and on the other hand, it can also provide an avoidance space for the extension of the clamping portion 31.

[0038] The pressing member 20 is movably disposed in the cavity M and is movable relative to the housing 10, so that the pressing member 20 has a first position and a second position relative to the housing 10. Among them, the pressing member 20 can be completely located in the cavity M or partially located in the cavity M, as long as the requirement of applying a force to the pressing member 20 can be met.

[0039] Further, when the pressing member 20 is in the first position, the clamping member 30 is in the clamping state. At this time, the connection between the connection assembly 01 and the track 03 can be realized through the clamping action of the clamping member 30; when the pressing member 20 is in the second position, the clamping member 30 is in the unlocking state. At this time, the clamping member 30 can be separated from the track 03, so that the connection assembly 01 can be removed from the track.

[0040] The transmission part 32 of the snap-in part 30 is located in the cavity M and is in transmission cooperation with the pressing part 20. By moving the pressing part 20 relative to the housing 10, a force is applied to the transmission part 32 to drive the snap-in part 30 to move in the limiting hole 111.

[0041] The elastic part 40 is elastically connected to the pressing part 20 and the housing 10 and is used to return the pressing part 20. Optionally, the elastic part 40 can be a spring, a rubber part, a rubber component, etc. Of course, it can also be of other types, which are not specifically limited here.

[0042] In the initial state, the pressing part 20 can be in the first position. When a force is applied to the pressing part 20, the pressing part 20 can overcome the elastic force of the elastic part 40 and move from the first position to the second position. At the same time, the elastic part 40 elastically contracts and stores elastic potential energy. After the force applied to the pressing part 20 is released, the elastic part 40 releases the elastic potential energy and makes the pressing part 20 move from the second position to the first position under the elastic force of the elastic part 40, thereby realizing the return of the pressing part 20. Moreover, due to the cooperation connection relationship between the pressing part 20 and the snap-in part 30, during the process of applying a force to the pressing part 20 and the process of releasing the force applied to the pressing part 20, the movement of the pressing part 20 can drive the snap-in part 30 to move accordingly, so that the snap-in part 30 can be switched between the snap-in state and the unlocking state.

[0043] To achieve the transmission cooperation between the snap-in part 30 and the pressing part 20, the pressing part 20 can be provided with a transmission groove 21, and the transmission part 32 of the snap-in part 30 is movably arranged in the transmission groove 21. In this way, the pressing part 20 can drive the snap-in part 30 to move, so that the snap-in part 31 retracts relative to the limiting hole 111 and disengages from the track 03, facilitating the removal of the connection component 01 from the track 03.

[0044] In addition, under the elastic action of the elastic part 40, the pressing part 20 drives the snap-in part 30 to move, so that the snap-in part 31 extends relative to the limiting hole 111 and engages with the track 03. In this way, the connection between the snap-in part 31 and the track 03 can be made more stable, preventing the snap-in part 31 from disengaging from the track 03 randomly.

[0045] Exemplarily, the transmission part 32 can be a transmission shaft, and the transmission shaft is movably arranged in the transmission groove 21 to achieve the transmission cooperation between the transmission part 32 and the pressing part 20, as Figure 4 and Figure 5 shown.

[0046] In the embodiment of the present application, the transmission part 32 of the clamping member 30 is matched with the transmission groove 21 of the pressing member 20 for transmission. In this way, under the elastic force of the elastic member 40, the pressing member 20 has a tendency to move relative to the shell 10, so that a certain limiting effect can be played on the clamping member 30 to prevent the clamping member 30 from moving arbitrarily and causing the clamping part 31 to be out of the track, thereby ensuring the stable connection between the connecting component 01 and the track 03; when it is necessary to separate the connecting component 01 from the track 03, a force is applied to the pressing member 20 and the elastic force of the elastic member 40 is overcome, so that the pressing member 20 moves relative to the shell 10, thereby moving the clamping member 30 relative to the shell 10 through the matching transmission groove 21 and the transmission part 32, and then the clamping part 31 is out of the track 03 to facilitate the separation of the connecting component 01 from the track 03.

[0047] Compared with the connection method using magnetic attraction or plastic deformation in the related art, the embodiment of the present application uses the movement of the clamping part 31 relative to the housing 10 to engage or release the clamping part with the track 03, which is convenient for installation or disassembly, and under the elastic force of the elastic member 40, the clamping member 30 can be limited by the pressing member 20 to prevent the clamping member 30 from moving arbitrarily and leaving the track 03, thereby improving the stability of the connection and helping to improve the load-bearing capacity of the connection assembly 01. Therefore, the embodiment of the present application can effectively solve the problems of poor stability and limited load-bearing capacity.

[0048] In some embodiments, the clamping portion 31 is movably disposed in the limiting hole 111 in a first direction, the pressing member 20 is movably disposed in the cavity M in a second direction perpendicular to the first direction, and the transmission groove 21 extends along the second direction and obliquely toward the first direction.

[0049] Optionally, both the first direction and the second direction may be in a horizontal plane. For example, the first direction may be a front-to-back direction, and the second direction may be a left-to-right direction, and the two may be perpendicular to each other. Of course, other forms are also possible, which are not specifically limited here.

[0050] Based on the above content, it can be known that the clamping member 30 can move in a first direction relative to the shell 10, and the pressing member 20 can move in a second direction relative to the shell 10, that is, the pressing member 20 and the clamping member 30 move in different directions. In this way, the force direction and the clamping direction can be converted, which can facilitate operation to a certain extent and is beneficial to reducing the volume of the connecting component 01.

[0051] The above-mentioned transmission groove 21 extends along the second direction and obliquely toward the first direction. It can also be understood that there is a certain angle between the extension direction of the transmission groove 21 and the second direction. The angle can range from 10° to 60°, for example, including 10°, 20°, 30°, 45°, 50°, 60°, etc. Of course, it can also be other angles, which are not specifically limited here.

[0052] Based on the above settings, when the pressing member 20 moves in the second direction, the side wall of the transmission groove 21 presses the transmission part 32, so as to drive the clamping member 30 through the transmission part 32. At the same time, the clamping member 30 is limited by the hole wall of the limiting hole 111, so that the clamping member 30 can move in the first direction in the limiting hole 111 to switch the state of the clamping member 30.

[0053] Exemplarily, the transmission groove 21 can be a long groove, such as an oblong groove, a rounded rectangular groove, an oval groove, etc.

[0054] In order to further improve the connection reliability between the connection component 01 and the track 03, the connection component 01 can include a plurality of clamping members 30. The connection reliability between the connection component 01 and the track 03 is ensured by respectively clamping the plurality of clamping members 30 to the track 03, so as to prevent the situation that the connection component 01 and the track 03 are accidentally separated due to the accidental detachment of some clamping members 30 from the track 03.

[0055] Of course, in order to improve the clamping efficiency or the unlocking efficiency of the plurality of clamping members 30 and the track 03, the plurality of clamping members 30 can be respectively in transmission cooperation with the transmission groove 21 of the pressing member 20 through the transmission part 32. In this way, the plurality of clamping members 30 can be driven to move synchronously by moving the pressing member 20 between the first position and the second position, so that the plurality of clamping members 30 can respectively switch between the clamping state and the unlocking state, thereby improving the clamping efficiency or the unlocking efficiency.

[0056] Correspondingly, the housing 10 can be provided with a plurality of limiting holes 111, and the plurality of clamping members 30 are arranged in the corresponding limiting holes 111 in a one-to-one correspondence and movably. In this way, the limiting effect on the plurality of clamping members 30 can be realized to prevent each clamping member 30 from moving randomly, and each clamping member 30 can also extend out of the cavity M to facilitate the clamping cooperation with the track 03.

[0057] In some more specific embodiments, the connection component 01 can include two clamping members 30. Correspondingly, the housing 10 is respectively provided with limiting holes 111 on two sides opposite to each other in the first direction, and the clamping parts 31 of each clamping member 30 are arranged in the corresponding limiting holes 111.

[0058] Based on the above settings, when the pressing member 20 is in the first position, both of the clamping members 30 are clamped to the track 03. In this case, the connection reliability and stability between the connection assembly 01 and the track 03 can be improved; when a force is applied to the pressing member 20, the pressing member 20 moves from the first position to the second position. Correspondingly, the two clamping members 30 are driven to move relatively closer in the first direction, so that the two clamping members 30 can be separated from the track 03 respectively, facilitating the separation of the connection assembly 01 from the track 03.

[0059] To enable the pressing member 20 to drive the two clamping members 30 to move, the pressing member 20 can be provided with two transmission grooves 21, and the transmission portions 32 of each clamping member 30 are arranged in the corresponding transmission grooves 21. In this way, when the pressing member 20 moves relative to the housing 10, the two clamping members 30 can be driven to move relatively closer respectively, facilitating the separation of the two clamping members 30 from the track 03.

[0060] Furthermore, the two transmission grooves 21 are symmetrically arranged with respect to the first plane, which is perpendicular to the first direction, and along the pressing direction of the pressing member 20, the distance between the two transmission grooves 21 in the first direction gradually increases, wherein the pressing direction is parallel to the second direction. Based on this setting, through the cooperative connection between the two transmission grooves 21 and the transmission portions 32 of the two clamping members 30, the symmetry of the movement of the two clamping members 30 in the first direction can be realized, so that the clamping portions 31 of the two clamping members 30 can be simultaneously separated from or simultaneously clamped to the track 03, improving the smoothness of the disassembly or clamping between the connection assembly 01 and the track 03.

[0061] To make it easier for the clamping member 30 to switch to the clamping state, the pressing member 20 can also be provided with an extrusion structure 22. Correspondingly, the clamping member 30 can also have a pressed portion 33, and the pressed portion 33 is arranged corresponding to the extrusion structure 22, as Figure 4 and Figure 5 shown. Based on this setting, when the elastic member 40 drives the clamping member 30 to move through the pressing member 20, the extrusion structure 22 abuts and cooperates with the pressed portion 33, so that the clamping portion 31 extends out relative to the limiting hole 111.

[0062] In addition, during the movement from the second position to the first position, the extrusion structure 22 can apply an extrusion force to the pressed portion 33, thereby driving the clamping member 30 to move towards the clamping position, facilitating the switching of the clamping member 30 to the clamping state.

[0063] It should be noted here that when the pressing member 20 is in the second position, the pressing structure 22 and the pressed portion 33 may be in contact with each other or may be separated by a certain distance; as the pressing member 20 moves from the second position to the first position, the pressing structure 22 can directly apply a pressing force to the pressed portion 33, or the pressing structure 22 gradually approaches the pressed portion 33 and contacts the pressed portion 33 to start applying a pressing force. Of course, in either case, the pressing effect on the engaging member 30 can be achieved to switch the engaging member 30 to the engaged state.

[0064] Continue to refer to Figure 4 and Figure 5 In some embodiments, the pressing structure 22 may include a first inclined pressing surface 221. Correspondingly, the pressed portion 33 may include a second inclined pressing surface 331. Both the first inclined pressing surface 221 and the second inclined pressing surface 331 extend obliquely along the second direction and towards the first direction, and the second inclined pressing surface 331 abuts against the first inclined pressing surface 221. Based on this setting, the acting force of the pressing member 20 can be transmitted to the engaging member 30 through the mutual pressing and cooperation between the first inclined pressing surface 221 and the second inclined pressing surface 331, so as to switch the engaging member 30 to the engaged state.

[0065] Optionally, the extending directions of the first inclined pressing surface 221 and the second inclined pressing surface 331 are the same to ensure the largest contact area between the two; in addition, the extending directions of the two may form a certain angle with the second direction, and the range of this angle may be from 10° to 60°, for example, including 10°, 20°, 30°, 45°, 50°, 60°, etc. Of course, other angles are also possible and are not specifically limited here.

[0066] In addition, the extending directions of both the first inclined pressing surface 221 and the second inclined pressing surface 331 may be the same as the extending direction of the transmission groove 21. In this way, the side wall of the transmission groove 21 can press the transmission portion 32, and the second inclined pressing surface 331 can press the first inclined pressing surface 221 to jointly drive the engaging member 30 to move, so as to increase the area of the driving action region for the engaging member 30, which is beneficial to improving the driving stability of the engaging member 30.

[0067] Refer to Figure 4, in some more specific embodiments, the connecting component 01 may include two clamping members 30. In order to enable the extrusion structure 22 to simultaneously extrude the two clamping members 30, the extrusion structure 22 may further include two first inclined extrusion surfaces 221, and the second inclined extrusion surfaces 331 of the pressed parts 33 of the two clamping members 30 are respectively arranged corresponding to the two first inclined extrusion surfaces 221. Based on this setting, when the pressing member 20 moves relative to the housing 10 under the elastic force of the elastic member 40, the two first inclined extrusion surfaces 221 of the extrusion structure 22 can respectively extrude the second inclined extrusion surfaces 331 of the pressed parts 33 of the two clamping members 30, so that the two clamping members 30 move away from each other, facilitating the clamping parts 31 of the two clamping members 30 to be respectively clamped to the track 03.

[0068] Furthermore, the two first inclined extrusion surfaces 221 are symmetrically arranged with respect to the second plane, which is perpendicular to the first direction, and along the pressing direction of the pressing member 20, the distance between the two first inclined extrusion surfaces 221 in the first direction gradually increases, wherein the pressing direction is parallel to the second direction. Based on this setting, by respectively extruding the two clamping members 30 through the two symmetrically arranged first inclined extrusion surfaces 221, the synchronism of the movement of the two clamping members 30 in the first direction can be achieved, so as to ensure that the clamping parts 31 of the two clamping members 30 are simultaneously clamped to the track 03, thereby improving the smoothness of the clamping between the connecting component 01 and the track 03.

[0069] To achieve a stable connection between the elastic member 40 and the pressing member 20, the pressing member 20 may be provided with a connection structure 23, such as Figure 4 shown, one end of the elastic member 40 is connected to the connection structure 23. In this way, the pressing member 20 can be restricted from moving randomly through the connection structure 23, ensuring the installation stability of the pressing member 20.

[0070] In addition, the other end of the elastic member 40 may be connected to the side wall of the housing 10 to ensure the stability of the other end of the elastic member 40.

[0071] Optionally, the connection structure 23 may include a connection protrusion or a connection groove, and one end of the elastic member 40 may be connected to the connection protrusion or the connection groove. Of course, the connection structure 23 may also adopt other forms, which are not specifically limited herein.

[0072] Taking the elastic member 40 as a spring as an example, one end of the spring can be sleeved outside the connection protrusion or embedded in the connection groove to prevent one end of the spring from moving randomly; the other end of the spring can abut against the side wall of the cavity M to apply a bearing force to the other end of the spring through the side wall of the cavity M.

[0073] In addition, the embodiment of the present application can also change the pressing force of the pressing member 20 by adjusting the elastic deformation of the elastic member 40, and increase the extrusion force of the pressing member 20 on the clamping member 30 by increasing the elastic deformation of the elastic member 40, so that the clamping member 30 in the clamped state is not easy to be unjammed, and thus the connecting component 01 can carry a heavier lamp 02 without falling off easily.

[0074] In order to improve the reliability of the connection between the connecting assembly 01 and the track 03, the clamping portion 31 may include a clamping hook 311. In the first direction, the clamping hook 311 is arranged on a side of the clamping member 30 away from the extrusion structure 22. Figure 5 As shown, this arrangement can effectively prevent the extrusion structure 22 from interfering with the engagement between the locking mechanism and the track 03, and improve the reliability of the connection through the engagement between the hook 311 and the track 03, effectively preventing the connection component 01 and the track 03 from being accidentally separated.

[0075] Exemplarily, the longitudinal section of the clamping portion 31 may be in an inverted L-shape. Of course, it may also be in other shapes, which are not specifically limited here.

[0076] refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 In some embodiments, the housing 10 may include a first shell unit 11 and a second shell unit 12, the first shell unit 11 and the second shell unit 12 are detachably connected, and a cavity M may be formed therebetween. Based on this configuration, when the pressing member 20 and the clamping member 30 need to be installed or removed, the first shell unit 11 and the second shell unit 12 may be separated to facilitate the installation or removal of the pressing member 20 and the clamping member 30.

[0077] Exemplarily, the first shell unit 11 and the second shell unit 12 may be detachably connected by means of a snap connection, a screw connection, a plug connection, or the like.

[0078] In addition, the first shell element 11 may be provided with an avoidance hole 112, such as Figure 2 and Figure 6 As shown, the avoidance hole 112 is connected to the cavity M, and the pressing surface of the pressing member 20 is arranged corresponding to the avoidance hole 112, so that the pressing surface can be exposed to facilitate the pressing operation of the pressing member 20.

[0079] The limiting hole 111 is provided in the first shell unit 11 , so that even if the first shell unit 11 and the second shell unit 12 are assembled together, the clamping member 30 can be extended out of the cavity M by the setting of the limiting hole 111 to prevent the clamping member 30 from being blocked.

[0080] To prevent the pressing member 20 from detaching from the housing 10, at least one of the pressing member 20 and the housing 10 may be provided with a blocking structure (not shown in the figure), such as a protrusion or other structures, to achieve the blocking effect on the pressing member 20 through the blocking structure, so as to prevent the pressing member 20 from sliding out of the cavity M and detaching from the housing 10.

[0081] Based on the above connection assembly 01, an embodiment of the present application also discloses a lighting device. The disclosed lighting device includes a lamp 02, a track 03, and the above connection assembly 01, as Figure 8 and Figure 9 shown. Among them, the lamp 02 is connected to the connection assembly 01, and the connection assembly 01 is in snap-fit connection with the track 03 through a snap member 30. In this way, the connection between the lamp 02 and the track 03 can be realized through the connection assembly 01, and the reliability of the connection can be ensured. In addition, a lamp 02 with a larger mass can be carried to improve the load-bearing capacity.
