DETAILED DESCRIPTION
[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0028] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.
[0029] In the following description, the terms "first, second, etc." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.
[0030] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.
[0031] The embodiment of the utility model provides a bracket connection assembly 1 and a lighting device, which includes a bracket connection assembly 1, a first body 2 and a second body 3, wherein the first body 2 is used for lighting, and the second body 3 is used for connecting a fixing device. It should be noted that the specific type of the lighting device is not limited here, and any device that requires lighting can be configured with the lighting device provided in the embodiment of the present application. For example, the lighting device may include a riding light and be fixed on a bicycle by connecting a fixing device, the lighting device may include a mining lamp and be fixed on a helmet by connecting a fixing device, and the lighting device may also include a night fishing light and be fixed on a night fishing rod by connecting a fixing device. Therefore, the first body 2 may be a lamp such as a riding light, a mining lamp or a night fishing light, and correspondingly, the fixing device connected to the second body 3 may be an outdoor device such as a bicycle, a helmet or a night fishing rod. It is understandable that the application scenario type of the embodiment of the utility model does not limit the structure of the bracket connection assembly 1 and the lighting device in the embodiment of the utility model.
[0032] In order to facilitate the explanation of the specific structure of the bracket connection assembly 1, refer to Figure 1 The present application takes the first body 2 as a riding light, the fixing device as a bicycle, and the second body 3 as a clamping seat fixed on the bicycle as an example for explanation. The clamping seat is used to clamp the handlebar of the bicycle. That is, the bracket connecting assembly 1 is used to connect the riding light and the clamping seat to fix the riding light on the bicycle. Figure 2The first body 2 has an installation cavity 21 and a through hole 22 connecting the installation cavity 21 with the outside. One end of the bracket connection component 1 is connected around the through hole 22 of the first body 2 and covers the through hole 22, and the other end is detachably connected to the second body 3 through a fastener 31. When the second body 3 is separated from the bracket connection component 1, the first body 2 can still remain connected to the bracket connection component 1. For example, when the second body 3 is removed alone to repair or replace parts in the second body 3, when the first body 2 is removed alone from the bicycle to charge the first body 2, and / or when repairing or replacing parts in the first body 2, the bracket connection component 1 can remain connected to the first body 2 and cover the through hole 22. Such a configuration does not affect the modular disassembly and assembly of the first body 2 and the second body 3, and is convenient for separate maintenance and replacement of components in the first body 2 and the second body 3, so as to extend the service life of the entire lighting device; it can also maintain the sealing of the through hole 22 of the first body 2, and the bracket connecting component 1 remains connected to the first body 2 while continuously shielding the through hole 22, so that dust impurities or liquid impurities are not easy to enter the first body 2 through the through hole 22, so as to maintain the power stability of the cycling light, thereby extending the service life of the cycling light.
[0033] Specifically, the fasteners 31 for detachably connecting the second body 3 and the bracket connection assembly 1 include, but are not limited to, threaded fasteners 31 such as bolts and screws, and clamping fasteners 31 such as elastic expansion strips and buckles. The present application does not limit the specific structure for realizing the detachable connection between the bracket connection assembly 1 and the second body 3, as long as one end of the bracket connection assembly 1 is connected around the through hole 22 of the first body 2, and the other end of the bracket connection assembly 1 is detachably connected to the second body 3.
[0034] Reference Figure 3 and Figure 4 The bracket connection assembly 1 includes a connection member 11 and a locking member 12. The connection member 11 has a first connection portion 111, a third connection portion 112 and a second connection portion 113 connected in sequence. The locking member 12 is movably connected to the first connection portion 111 and is used to lock the first connection portion 111 in the first body 2 (such as Figure 3 shown). Figure 6 for Figure 5 Cross-sectional view in the AA direction, refer to Figure 6, the third connection part 112 passes through the first body 2 and connects the first connection part 111 and the second connection part 113. The second connection part 113 is used to connect the second body 3. Therefore, the aforementioned "connector 11 is used to connect the other end of the second body 3" is on the second connection part 113, that is, the second body 3 and the second connection part 113 are detachably connected outside the installation cavity 21. It should be noted that the embodiment of the present application divides the connector 11 into the first connection part 111, the third connection part 112 and the second connection part 113, which means that the connector 11 is roughly divided into three areas according to the function of each component, rather than dividing the connector 11. In other words, the first connection part 111, the second connection part 113 and the third connection part 112 can be integrally formed. Of course, one or two of the first connection part 111, the second connection part 113 and the third connection part 112 can also be separately formed as an independent component.
[0035] In order to further understand the positional relationship between the first connection portion 111, the second connection portion 113 and the third connection portion 112, refer to Figure 7 The first connection part 111 indicates the part of the connection member 11 located in the installation cavity 21 of the first body 2 and locked or separated from the locking member 12, so that the connection member 11 is locked or separated from the first body 2; the second connection part 113 indicates the part of the connection member 11 located outside the installation cavity 21 of the first body 2 and shielding the through hole 22, and the third connection part 112 indicates the part that penetrates the first body 2 and connects the first connection part 111 and the second connection part 113. The second connection part 113 shields at least the through hole 22 outside the first body 2, which means that the end surface area (right end surface area) of the second connection part 113 connected to the outer side wall 24 of the first body 2 is at least larger than the opening area of the through hole 22, and the through hole 22 is shielded by the second connection part 113 and isolated from the external atmospheric environment, and it is difficult for dust impurities or liquid impurities to bypass the larger second connection part 113 to enter the through hole 22, and thus it is difficult for substances such as dust impurities or liquid impurities to enter the installation cavity 21 through the through hole 22 to affect the power stability of the first body 2.
[0036] In order to facilitate understanding of the effect of the connecting member 11 and the locking member 12 on the first body 2 after being locked, refer to Figure 7, when the connecting member 11 and the first main body 2 are in a locked state, the locking member 12 presses against the inner side wall 23 of the first main body 2 and locks the first connecting portion 111, and the locking member 12 presses against the first connecting portion 111 along the penetration direction of the third connecting portion 112 (from left to right), that is, after the locking member 12 locks the first connecting portion 111, it provides a pressing force from left to right to the first connecting portion 111, so that the first connecting portion 111 has a movement tendency along the penetration direction (from left to right), and then the second connecting portion 113 presses against the outer side wall 24 of the first main body 2 to the right, so as to achieve the sealing of the through hole 22. It can be understood that the direction pointing to the penetration direction is the direction in which the second connecting portion 113 presses against the outer side wall 24, and the direction away from the penetration direction is the direction in which the locking member 12 presses against the inner side wall 23, and part of the side wall of the first main body 2 is clamped between the second connecting portion 113 and the locking member 12, then in Figure 7 In the left and right directions shown, no matter in which direction the bracket connection assembly 1 moves due to vibration under bumpy road conditions, the bracket connection assembly 1 is stably pressed against the first body 2 and reliably seals the through hole 22. Specifically, the direction in which the connection member 11 intends to move from right to left is the direction in which the connection member 11 is separated from the outer side wall 24 of the first body 2, and the locking member 12 is pressed against the inner side wall 23 to limit the freedom of the connection member 11 to separate from the outer side wall 24, so that the connection member 11 is stably connected to the first body 2 and seals the through hole 22; the direction in which the connection member 11 intends to move from left to right is the direction in which the locking member 12 is separated from the inner side wall 23 of the first body 2, and the second connection part 113 is pressed against the outer side wall 24 to limit the freedom of the locking member 12 to separate from the inner side wall 23, so that the locking member 12 is stably pressed against the first connection part 111 and tightens the second connection part 113 to the right. In addition, because the locking member 12 and the connecting member 11 are locked in the first body 2, under normal use, it is difficult for the user to touch the position where the locking member 12 and the connecting member 11 are connected, so the connecting member 11 is difficult to be accidentally touched by external force and separated from the locking member 12.
[0037] It is explained that the “outer wall 24” mentioned above refers to the boundary contour of the side of the first body 2 close to the atmospheric environment; the “inner wall 23” refers to the boundary contour of one side of the first body 2 enclosing the mounting cavity 21, and the through hole 22 connects the outer wall 24 and the inner wall 23 of the first body 2.
[0038] In some possible implementations, reference Figure 7In order to facilitate the locking member 12 to lock the first connection part 111 in the installation cavity 21, the third connection part 112 can be made of a flexible material such as silicone or rubber, so that the third connection part 112 can be elastically expanded after the locking member 12 locks the first connection part 111. The elastic force of the third connection part 112 to restore the deformation makes the second connection part 113 close to the outer wall 24, and the locking member 12 close to the inner wall 23, thereby improving the sealing of the through hole 22. Of course, the first connection part 111 and / or the second connection part 113 can also be made of a flexible material to improve the sealing of the through hole 22. It can be understood that even if the connecting member 11 is not made of a flexible material, after the locking member 12 is pressed against the first connection part 111 along the penetration direction, the second connection part 113 is still pulled in the penetration direction and has a movement tendency close to the first body 2, so that the second connection part 113 is pressed against the outer wall 24 of the first body 2, and the through hole 22 can still be sealed.
[0039] The embodiment of the present application provides a bracket connection assembly 1, which includes a connection member 11 and a locking member 12. The connection member 11 has a first connection portion 111, a third connection portion 112 and a second connection portion 113 connected in sequence. The first connection portion 111 is locked or separated with the locking member 12 in the first body 2, so that the connection member 11 is locked or separated with the first body 2; the second connection portion 113 is used to be detachably connected with the second body 3 outside the first body 2; the third connection portion 112 penetrates the through hole 22 on the first body 2. After the locking member 12 locks the first connection portion 111, the side (left side) of the locking member 12 away from the penetration direction is pressed against the inner side wall 23 of the first body 2, and the side (right side) of the locking member 12 along the penetration direction is pressed against the first connection portion 111, so that the first connection portion 111 has a movement tendency to move along the penetration direction, the second connection portion 113 has a movement tendency to approach the first body 2 along the penetration direction, and the second connection portion 113 is pressed against the outer side wall 24 of the first body 2. In this way, when the connecting member 11 and the first body 2 are in a locked state, part of the side wall of the first body 2 is clamped between the second connecting portion 113 and the locking member 12, the inner side wall 23 and the outer side wall 24 of the first body 2 are both in close contact with the bracket connecting assembly 1, the locking member 12 limits the freedom of the connecting member 11 to be separated from the first body 2, and the connecting member 11 also limits the freedom of the locking member 12 to be separated from the first body 2, and the bracket connecting assembly 1 is stably connected to the first body 2 and reliably seals the through hole 22. The disassembly position of the bracket connecting assembly 1 and the first body 2 is inside the first body 2. Under normal use, it is difficult for the user to touch the disassembly position of the bracket connecting assembly 1 and the first body 2. Even if the second body 3 is separated from the bracket connecting assembly 1, the bracket connecting assembly 1 remains connected to the first body 2, so that the through hole 22 of the first body 2 is continuously sealed by the connecting member 11. The structure of the bracket connection assembly 1 provided in the embodiment of the present application does not affect the modular disassembly and assembly of the first body 2 and the second body 3, and the components in the first body 2 and / or the second body 3 can be repaired or replaced separately; at the same time, it can also maintain the sealing of the through hole 22 of the first body 2, and substances such as dust impurities or liquid impurities are not easy to enter the first body 2 through the through hole 22, so as to maintain the lighting stability and service life of the first body 2.
[0040] In some embodiments, reference Figure 4 and Figure 7 The bracket connection assembly 1 also includes a sealing member 13, which is sleeved on the outer edge of the third connection portion 112. When the third connection portion 112 passes through the through hole 22 and extends into the installation cavity 21, the sealing member 13 abuts against the second connection portion 113, the third connection portion 112, and the outer side wall 24 of the first body 2 (such as Figure 7 Specifically, refer to Figure 7, the sealing member 13 abuts between the second connection part 113 and the outer side wall 24. When the locking member 12 locks the first connection part 111, the locking member 12 abuts against the first connection part 111 along the penetration direction (from left to right), and the first connection part 111 drives the second connection part 113 to move rightward, so that the sealing member 13 is pressed between the second connection part 113 and the outer side wall 24, and the sealing member 13 is deformed under pressure. The sealing member 13 has an elastic force to restore the deformation and expand, and the elastic force makes the sealing member 13 abut against the second connection part 113 and the outer side wall 24, reducing the assembly gap between the connection member 11 and the first body 2, and further improving the sealing performance of the through hole 22. Compared with the implementation method of using a flexible material to make the third connecting part 112 to reduce the assembly gap between the connecting member 11 and the first main body 2, the embodiment of the present application reduces the assembly gap between the connecting member 11 and the first main body 2 through the sealing member 13, so that the connecting member 11 can be integrally formed with the first connecting part 111, the second connecting part 113 and the third connecting part 112, thereby reducing the processing difficulty of the connecting member 11.
[0041] In some embodiments, reference Figure 7 and Figure 8 The outer side wall 24 of the first body 2 has a groove 25 (such as Figure 8 As shown in FIG. 1 , the groove 25 is arranged around the edge of the through hole 22, that is, the through hole 22 is formed in the groove 25. Figure 7 As shown in the figure, the second connection part 113 moves along the penetration direction through the groove 25 to press the seal 13 into the groove 25. In this way, when the connection part 11 and the first body 2 are in a locked state, the seal 13 abuts against the groove 25, the end wall of the groove 25 blocks and clamps the seal 13 in the up-down direction, and the second connection part 113 blocks and clamps the seal 13 in the left-right direction. The seal 13 is isolated from the external environment, and the seal 13 will not directly contact the dust impurities or liquid impurities in the external environment. The aging speed of the seal 13 is delayed, thereby extending the service life of the seal 13, so that the seal 13 can maintain the sealing of the through hole 22 for a long time. At the same time, the second connection part 113 after connection is partially located in the groove 25, and the groove 25 can also limit the connection position of the second connection part 113, so that the seal 13 can be stably squeezed, and the reliability of the sealing of the through hole 22 is improved. Furthermore, dust impurities or liquid impurities outside the first body 2 need to pass through the stepped passage formed by the groove 25 and the through hole 22 to enter the first body 2, which greatly increases the difficulty for dust impurities or liquid impurities to enter the first body 2 and further improves the sealing performance of the first body 2.
[0042] Reference Figure 8, the side of the first body 2 closest to the external environment is defined as the first side 26, and the side of the first body 2 disposed between the first side 26 and the inner side wall 23 is defined as the second side 27. It can be understood that the second side 27 is the groove wall of the groove 25, and the first side 26 and the second side 27 form the outer side wall 24. In some possible embodiments, the sealing member 13 can also be closely attached to the first side 26, but in contrast, referring to Figure 7 The through hole 22 is arranged between the second side 27 and the inner side wall 23, which increases the path for dust impurities or liquid impurities to be transferred from the external environment to the through hole 22. The dust impurities or liquid impurities first enter the groove 25 and then enter the installation cavity 21 through the through hole 22. Due to the isolation of the sealing member 13 arranged in the groove 25, it is difficult for dust impurities or liquid impurities to pass through the groove 25 to reach the position where the through hole 22 is located, so that the sealing performance of the first body 2 is better.
[0043] In some embodiments, reference Figure 3 and Fig. 9 The locking member 12 has a body 121, and a first plug-in portion 122 and / or a second plug-in portion 123 connected to the body 121. The first plug-in portion 122 and the second plug-in portion 123 are both used to plug into the first connecting portion 111 (such as Figure 3 That is, the locking member 12 may include a body 121 and a first plug-in portion 122, may include a body 121 and a second plug-in portion 123, or may include a body 121, a first plug-in portion 122 and a second plug-in portion 123. The present application does not limit the specific structure of the locking member 12, as long as the locking member 12 can be plugged into the first connecting portion 111, so that the first connecting portion 111 is connected as shown. Figure 7 Just lock it in the installation cavity 21 as shown.
[0044] In order to facilitate the explanation of the locking principle of the locking member 12 and the first connecting portion 111, the locking member 12 includes a body 121, a first plug-in portion 122 and a second plug-in portion 123 as an example for explanation:
[0045] Reference Figure 4The first connection portion 111 has a third plug-in portion 1111 and a fourth plug-in portion 1112. The third plug-in portion 1111 is compatible with the first plug-in portion 122, and the fourth plug-in portion 1112 is compatible with the second plug-in portion 123. For example, when the first plug-in portion 122 is a plug-in strip, the third plug-in portion 1111 is a slot; when the first plug-in portion 122 is a tongue, the third plug-in portion 1111 is a slot. In some embodiments shown in the schematic diagram of the present application, the first plug-in portion 122 and the second plug-in portion 123 are both plug-in strips, and the third plug-in portion 1111 and the fourth plug-in portion 1112 are both slots. When the locking member 12 locks the first connecting portion 111, the body 121 abuts against the first connecting portion 111 in the insertion direction of the locking member 12, that is, the body 121 abuts against the upper end surface of the first connecting portion 111, the first plug-in portion 122 is plugged into the third plug-in portion 1111, and the second plug-in portion 123 is plugged into the fourth plug-in portion 1112. The first plug-in portion 122 and the second plug-in portion 123 act together, so that the locking member 12 is closely attached to the inner side wall 23 at multiple positions (such as Figure 2 As shown), the seal 13 is compressed at multiple positions. In addition, the locking member 12 is detachably connected to the connecting member 11, which is convenient for the user to repair or replace the locking member 12 and / or the connecting member 11 separately, and is also convenient for replacing the seal 13 separately after the seal 13 ages.
[0046] In some embodiments, reference Figure 4 When the locking member 12 has a first plug-in portion 122, the first plug-in portion 122 and / or the third plug-in portion 1111 are provided with a guide structure 10; when the locking member 12 has a second plug-in portion 123, the second plug-in portion 123 and / or the fourth plug-in portion 1112 are provided with a guide structure 10. The guide structure 10 includes but is not limited to a bevel, a fillet, and a chamfer. In the embodiment shown in the schematic diagram of the present application, refer to Fig. 9 , the guide structure 10 of the first plug-in portion 122 is a rounded corner, and the guide structure 10 of the second plug-in portion 123 is an inclined surface; Figure 4 The guide structures 10 of the third plug-in portion 1111 and the fourth plug-in portion 1112 are both chamfered. The setting of the guide structure 10 facilitates the smooth insertion of the locking member 12 into the first connecting portion 111, so that the first connecting portion 111 can be smoothly inserted into the first connecting portion 111. Figure 7 As shown, it is locked in the mounting cavity 21.
[0047] In some embodiments, reference Figure 4 The second plug-in portion 123 is provided with a bent portion 1231, and the bent portion 1231 extends along the insertion direction. The first connecting portion 111 is provided with a hook edge 1113, and the hook edge 1113 extends away from the insertion direction. That is, the bent portion 1231 extends along Figure 4 As shown, the edge 1113 extends from left to right. Figure 4As shown, the locking member 12 extends from right to left. Figure 3 As shown in FIG. 1 , the bent portion 1231 is located in the fourth plug-in portion 1112 and abuts against the hook edge 1113. It can be understood that the bent portion 1231 and the hook edge 1113 are buckled left and right. This arrangement allows the bent portion 1231 and the hook edge 1113 to block each other in the horizontal direction. Figure 3 The locking member 12 and the connecting member 11 are connected stably, and the second connecting portion 113 is not offset in the front and rear directions. Figure 7 As shown, it stably abuts against the first body 2 outside the mounting cavity 21 .
[0048] In some embodiments, reference Figure 4 , in the plugging direction, the length of the first plugging portion 122 is greater than the length of the third plugging portion 1111; and / or, the length of the second plugging portion 123 is greater than the length of the fourth plugging portion 1112. In some embodiments shown in the schematic diagram of the present application, the length of the second plugging portion 123 is greater than the length of the fourth plugging portion 1112, then Figure 4 In the vertical direction shown, the upper and lower ends of the first connecting portion 111 are subjected to substantially equal abutment forces from the second plug-in portion 123, that is, the upper and lower ends of the second connecting portion 113 are subjected to substantially equal pulling forces from left to right. Figure 7 As shown in the schematic diagram, the gaps between the upper and lower ends of the second connecting portion 113 and the first main body 2 are roughly equal, and the second connecting portion 113 is closely attached to the first main body 2 in the up and down directions without any deviation, which helps the second connecting portion 113 to stably press the seal 13 or the outer wall 24 to achieve sealing of the through hole 22.
[0049] In some embodiments, reference Fig. 9 The second plug-in parts 123 are provided with a plurality of them, each of which is located at both sides of the first plug-in part 122, and the second plug-in parts 123 with a longer length and / or a bent part 1231 are distributed on both sides of the first plug-in part 122, so that the locking member 12 Figure 3 The first connecting portion 111 is stably pressed against the first connecting portion 111 in the front-to-back direction as shown, and the rightward pulling forces on the front and rear ends of the first connecting portion 111 are substantially equal (as shown in FIG. Figure 3 As shown in FIG. 1 , the second connecting portion 113 is difficult to deviate from the first main body 2 in the front-to-back direction (as shown in FIG. 1 ). Figure 7 See Figure 7 The second connection portion 113 is in close contact with the first body 2 in all directions, which helps the second connection portion 113 to press the sealing member 13 , thereby improving the sealing performance of the first body 2 .
[0050] In some embodiments, reference Figure 2The first body 2 includes a shell 201 and a positioning group 202. The shell 201 is hollow inside to form a mounting cavity 21. The positioning group 202 is arranged in the mounting cavity 21. The through hole 22 passes through the side wall of the shell 201. The mounting cavity 21 is connected to the outside through the through hole 22. The groove 25 is arranged outside the shell 201, that is, the opening of the groove 25 faces the outside of the shell 201. Figure 7 When the connecting member 11 and the first body 2 are in a locked state, the positioning group 202 is at least used to block the locking member 12 in the plugging direction away from the locking member 12. The plugging direction of the locking member 12 is Figure 7 As shown in the top-to-bottom direction, that is, the positioning group 202 blocks the locking member 12 at least above the locking member 12, so that the locking member 12 will not be separated from the connecting member 11 in the bottom-to-top direction due to vibration or shaking. The locking member 12 stably locks the connecting member 11, which is beneficial for the connecting member 11 to maintain the sealing of the through hole 22.
