Referring to fig. 1, one embodiment of the present application provides a bicycle lamp assembly comprising a lamp body 1, a mounting seat 2 and a fixing assembly 3; the lower end of the mounting seat 2 or the upper end of the fixing component 3 is convexly provided with a positioning ring 21, and correspondingly, the upper end of the fixing component 3 or the lower end of the mounting seat 2 is convexly provided with a positioning column 311 and a plurality of positioning teeth 312; that is, when the positioning ring 21 is located at the lower end of the mounting base 2, the positioning post 311 and the plurality of positioning teeth 312 are located at the upper end of the fixing assembly 3; similarly, when the positioning ring 21 is located at the upper end of the fixing assembly 3, the positioning post 311 and the plurality of positioning teeth 312 are located at the lower end of the mounting base 2. The positioning teeth 312 are equally spaced apart from the outer side of the positioning post 311 along the circumferential direction of the positioning post 311 (as shown in fig. 8 and 9), and the outer ring surface of the positioning post 311 is rotatably and axially slidably connected to the inner ring surface of the positioning ring 21 (as shown in fig. 16); a plurality of tooth grooves 211 (as shown in fig. 6 and 7) are formed in the positioning ring 21 at equal intervals along the circumferential direction at one end facing the positioning teeth 312, and when the plurality of tooth grooves 211 are respectively butted with the plurality of positioning teeth 312, the relative rotation between the positioning ring 21 and the positioning column 311 is limited; the bicycle lamp assembly further includes a fastener 4 (shown in fig. 4 and 5), the fastener 4 being disposed between the mounting block 2 and the fixing assembly 3, and the fastener 4 being used to limit the separation of the positioning teeth 312 from the tooth slots 211. When the bicycle lamp is used, the fixing assembly 3 is arranged on a bicycle frame (for example, a handlebar), and then the bicycle lamp body 1 is arranged on the mounting seat 2, so that the installation and the fixation can be realized. When the irradiation azimuth of the car lamp body 1 needs to be adjusted, the fastener 4 is only required to be loosened firstly, the plurality of positioning teeth 312 are separated from the plurality of tooth grooves 211, the car lamp body 1 can be rotated around the axis of the positioning column 311 so as to adjust the irradiation azimuth of the car lamp body 1, after adjustment, the car lamp body is locked again through the fastener 4, the plurality of positioning teeth 312 are respectively clamped in the plurality of tooth grooves 211, and relative rotation is generated between the positioning column 311 and the positioning ring 21 (namely between the mounting seat 2 and the fixing assembly 3) so as to maintain the constant angle of the car lamp body 1 and have higher stability. In addition, through the cooperation between the locating column 311 and the locating ring 21, on one hand, the strength of the connecting position between the mounting seat 2 and the fixed component 3 can be improved, the bearing capacity is stronger, stronger impact can be resisted, and the mounting seat 2 is not easy to break when the bicycle falls down or collides; on the other hand, the diameter of the positioning ring 21 is increased by the matching method, and on the premise that the number of the tooth grooves 211 (namely the positioning teeth 312) is the same, the large-size positioning ring 21 can increase the depth of the tooth grooves 211, and the height of the positioning teeth 312 is also increased, so that the strength of interconnection between the positioning teeth 312 and the tooth grooves 211 is improved.
Referring to fig. 2-9, in some embodiments of the present application, the positioning ring 21 is formed on the lower end surface of the mounting base 2 (as shown in fig. 7), and the positioning post 311 and the positioning teeth 312 are formed on the upper end surface of the fixing assembly 3 (as shown in fig. 8 and 9); the lower sidewall of the car lamp body 1 is provided with a positioning groove 11, and the lower sidewall of the positioning groove 11 is provided with a U-shaped groove 12 (shown in fig. 2 and 3) in a downward penetrating way. The mounting seat 2 is of a plate-shaped structure (shown in fig. 6), the mounting seat 2 is slidably connected to the positioning groove 11, and the positioning ring 21 is slidably connected to the U-shaped groove 12 (shown in fig. 14 and 15); the bicycle lamp assembly further comprises a locking piece 5, wherein the locking piece 5 is arranged between the bicycle lamp body 1 and the mounting seat 2, and the locking piece 5 is used for limiting the mounting seat 2 to slide in the positioning groove 11. When the car lamp body 1 is installed, the positioning groove 11 is only required to be connected to the installation seat 2 in a sliding mode, and the car lamp body is locked through the locking piece 5, so that the installation is convenient. In addition, since other structures, such as a battery, a circuit board, a light emitting assembly, etc., need to be mounted inside the lamp body 1, the volume of the lamp body 1 is generally large; because the structure that forms constant head tank 11 wraps up in the outside of mount pad 2 again, consequently, when constant head tank 11 is located car light body 1, can effectually utilize the space of car light body 1 to improve the size of constant head tank 11, make the whole sliding connection of mount pad 2 in constant head tank 11, and go-between 21 sliding connection is in U-shaped groove 12, thereby make the joint strength between car light body 1 and the mount pad 2 higher, the tolerance is stronger, more shock-resistant, stability is higher.
Referring to fig. 7 and 21, in some embodiments of the present application, two reinforcing ribs 22 (as shown in fig. 7) are symmetrically disposed on the lower end surface of the mounting base 2, one ends of the two reinforcing ribs 22 are connected to the positioning ring 21, and the sides of the two reinforcing ribs 22, which are offset from each other, are slidably connected to the U-shaped groove 12 (as shown in fig. 21). On the one hand, the reinforcing ribs 22 can improve the strength of the mounting seat 2 and the connection strength between the positioning ring 21 and the mounting seat 2, so that the mounting seat 2 and the positioning ring 21 have stronger bearing capacity, are more impact-resistant and have higher stability; on the other hand, the side sliding connection that deviates from each other on two strengthening ribs 22 is in U-shaped groove 12, can further improve the joint strength between car light body 1 and mount pad 2 for the bearing capacity between car light body 1 and the mount pad 2 is stronger, and is more shock-resistant, and stability is higher.
Referring to fig. 3 and 20, in some embodiments of the present application, the upper sidewall of the positioning groove 11 is disposed obliquely upward, so that the distance between the upper sidewall and the lower sidewall of the positioning groove 11 gradually increases along the direction that the mounting seat 2 is separated from the positioning groove 11 (as shown in fig. 20), and the inclined structure is beneficial to demolding and reduces the processing difficulty. The upper side wall of the positioning groove 11 is provided with a convex rib 14 along the sliding direction of the mounting seat 2 (as shown in fig. 3), and the lower end surface of the convex rib 14 is slidably connected to the upper end surface of the mounting seat 2 (as shown in fig. 20). On the one hand, the convex ribs 14 can improve the structural strength of the positioning groove 11, on the other hand, the convex ribs 14 can prevent the upper end surface of the mounting seat 2 from contacting the upper side wall of the positioning groove 11 (as shown in fig. 15 and 16), so that the sliding resistance between the mounting seat 2 and the positioning groove 11 can be reduced, and the mounting and the dismounting are convenient; and a certain gap can be formed between the upper end surface of the mounting seat 2 and the upper side wall of the positioning groove 11, so that enough buffer area is provided during collision, and the outer structure of the positioning groove 11 and the mounting seat 2 deform to offset most impact force, so that breakage caused by rigid collision is avoided.
Referring to fig. 15 and 16, in some embodiments of the present application, the intervals between the both side surfaces of the mount 2 are sequentially reduced from top to bottom so that an included angle a is formed between the side surface of the mount 2 and the side wall of the positioning groove 11, and 2 ° -a-6 °. The layout mode can reduce the sliding resistance between the mounting seat 2 and the positioning groove 11, and is convenient to mount and dismount; on the other hand, when the bicycle falls, for example, when the bicycle falls to the right, the right side of the lamp body 1 receives a force F 1 (as shown in fig. 15), the car lamp body 1 (i.e. the outer structure of the positioning groove 11) has a movement tendency of deflecting leftwards, at this time, as shown in fig. 16, under the action of the included angle a, the outer structure of the positioning groove 11 is allowed to deflect leftwards, so that most of impact force is counteracted by deformation, and breakage caused by rigid collision is avoided; when the outer structure of the positioning groove 11 deflects leftwards until the left side surface of the mounting seat 2 is in contact with the side surface of the positioning groove 11, the outer structure of the positioning groove 11 is further prevented from being deformed, and breakage caused by overlarge deformation is prevented; in addition, under the condition that a gap is formed between the upper end surface of the mounting seat 2 and the upper side wall of the positioning groove 11 by combining the convex rib 14, when the outer structure of the positioning groove 11 deflects leftwards, the contact between the upper left corner of the mounting seat 2 and the upper side wall of the positioning groove 11 can be avoided, the deformation capability of the outer structure of the positioning groove 11 can be improved, and the effect of improving the included angle a can be assisted. According to experiments, the angle of the included angle a is not too small, and when the angle of the included angle a is smaller than 2 degrees, the action effect is not obvious; of course, the angle of the included angle a is not too large, and when the angle of the included angle a is larger than 6 degrees, the external structure of the positioning groove 11 is easy to break due to overlarge deformation; after comprehensive comparison, the included angle a is suitable for 2-6 degrees, and preferably, when the included angle a is 4 degrees, the effect is optimal. The left and upper end surfaces of the mounting base 2 and the left and lower surfaces of the mounting base 2 should be rounded to prevent shearing of the cornersCutting.
Referring to fig. 17, 18 and 19, in some embodiments of the present application, the distance between the two sides of the mounting seat 2 gradually increases along the direction that the mounting seat 2 is separated from the positioning groove 11, so that an included angle b is formed between the side of the mounting seat 2 and the side wall of the positioning groove 11, and b is greater than or equal to 0.5 ° and less than or equal to 0.7 °; an arc-shaped part 23 (shown in fig. 3) protrudes from one end, close to the inside of the positioning groove 11, of each side face of the mounting seat 2, and the outer arc surface of the arc-shaped part 23 is slidably connected to the side wall (shown in fig. 18) of the positioning groove 11. The layout mode can reduce the sliding resistance between the mounting seat 2 and the positioning groove 11, and is convenient for mounting and dismounting; in addition, when the bicycle falls, for example, when the bicycle falls to the right, the front end of the lamp body 1 normally contacts the ground, and the external structure of the positioning groove 11 receives the acting moment F 2 On the one hand, the action moment acts as an action force F 1 On the other hand, the outer structure of the positioning groove 11 also has a motion trend of anticlockwise deflection (as shown in fig. 17), and at this time, as shown in fig. 18 and 19, under the action of the included angle b, the outer structure of the positioning groove 11 is allowed to anticlockwise deflect so as to offset most of the acting force through deformation and prevent fracture caused by rigid collision; meanwhile, under the action of the arc-shaped part 23, when the outer structure of the positioning groove 11 deflects anticlockwise, the right side wall of the positioning groove 11 is always contacted with the outer arc surface of the arc-shaped part 23, so that the acting force of the right side wall of the positioning groove 11 on the mounting seat 2 can be dispersed, and the stress concentration is avoided.
Referring to fig. 6, 7 and 20, in some embodiments of the present application, a clamping groove 13 (as shown in fig. 3) is formed on an upper sidewall of the positioning groove 11; two mutually symmetrical strip holes 24 (as shown in fig. 6) are formed in the upper end face of the mounting seat 2 in a downward penetrating manner at one end deviating from the arc-shaped part 23, and one end deviating from the arc-shaped part 23 on the strip hole 24 penetrates to the outer side of the mounting seat 2, so that an elastic part 25 is formed in a region between the two strip holes 24 on the mounting seat 2, and a pressing part 252 is arranged at one end deviating from the mounting seat 2 on the elastic part 25; the locking piece 5 is a buckle, and the buckle is arranged on the upper end surface of the elastic part 25; when the mounting seat 2 slides into the positioning groove 11, the upper side wall of the positioning groove 11 forces the elastic part 25 to deform downwards through the buckle until the elastic part 25 recovers deformation when the buckle is aligned with the clamping groove 13, so that the buckle is clamped in the clamping groove 13; when the pressing portion 252 is pressed downward, the elastic portion 25 can be forced to deform downward to disengage the buckle from the card slot 13. As shown in fig. 20, when the vehicle lamp body 1 is mounted, the upper side wall of the positioning groove 11 can force the elastic part 25 to deform by buckling only when the positioning groove 11 is connected to the mounting seat 2 in a sliding manner; when the buckle is clamped into the clamping groove 13, locking can be realized, so that relative sliding between the positioning groove 11 and the mounting seat 2 is prevented. When the buckle is detached, the buckle can be separated from the clamping groove 13 only by pressing the pressing part 252 downwards, so that the detachment is realized.
