Description

Technical Field

[0001] This application relates to the field of bicycle taillight technology, specifically to a magnetic bicycle lamp holder and a bicycle lamp having the holder. Background Technology

[0002] In the wave of technological development, bicycles have gradually evolved from a primary means of transportation into a form of exercise. With increasing public awareness of safety, cycling enthusiasts are paying more and more attention to safety while riding, especially at night or in low-light conditions. They often install luminous taillights to improve visibility in dim environments. There are generally two common methods for installing bicycle taillights: one where the lamp holder is fixed to the bicycle, and the lamp body and holder can be separated; the other where the lamp holder and lamp head are integrated and directly attached to the bicycle. Because luminous bicycle taillights contain built-in lithium batteries, they need to be frequently removed and recharged. Therefore, most bicycle lights on the market are currently modular. To facilitate disassembly and assembly, magnetic connection methods have emerged. However, lights relying solely on magnetic connections have poor stability; when the light is subjected to vibration, the lamp head is prone to detachment, damage, or loss, as shown in CN219565325U. Utility Model Content

[0003] In view of this, this application provides a magnetic bicycle lamp holder and a bicycle lamp having the lamp holder, in order to solve the technical problem of low stability of existing magnetic bicycle lamps.

[0004] To achieve the above objectives, this application provides the following technical solution: A magnetic bicycle lamp holder includes a mounting part, a mating cavity, and a magnetic part. The mating cavity is provided with an elastic retaining member. The magnetic force of the magnetic part is used to attract and insert the plug of the lamp head into the mating cavity. The elastic retaining member is used to elastically engage with the annular groove provided on the plug of the lamp head.

[0005] Furthermore, the magnetic suction part is located at the bottom of the insertion cavity.

[0006] Furthermore, the elastic clamp is a C-shaped elastic clamp.

[0007] Furthermore, the sidewall of the insertion cavity has a notch that communicates with the outside, and the opening of the elastic clamping member corresponds to the position of the notch.

[0008] Furthermore, the bottom of the insertion cavity is provided with an elastic retainer located within the notch.

[0009] Furthermore, the side of the elastic clamping member facing the insertion cavity has a guide slope.

[0010] Furthermore, the elastic engaging member has multiple locking teeth that mate with the annular groove, and a guide ramp is located on the locking teeth.

[0011] Furthermore, a C-shaped retaining ring is provided on the bottom of the mating cavity, and the opening position of the retaining ring corresponds to the notch position.

[0012] Furthermore, the bottom of the insertion cavity has a boss that is fitted and installed with the elastic retaining member, and the limiting ring is located on the boss.

[0013] Based on the magnetic bicycle lamp holder disclosed above, this application discloses another technical solution: A bicycle lamp including the magnetic bicycle lamp holder described above, also includes a lamp head, the back of which has a plug, the plug being T-shaped, and the plug having a plugging guide cone surface.

[0014] Furthermore, the limiting ring has a tapered hole that mates with the insertion guide tapered surface.

[0015] Compared with the prior art, the beneficial effects of this application are: 1. In this application, the magnetic connection makes it easy to install and remove the lamp holder and avoids repeated disassembly of the lamp base, making it convenient to use.

[0016] 2. In this application, the magnetic part is set on the lamp holder, and the magnetic part may not be set on the lamp head, so as to avoid damage caused by the lamp head attracting and colliding with iron materials when placed independently, and at the same time, the number of magnets used can be reduced; the elastic clamping part cooperates with the ring groove on the lamp head to make the lamp head installation highly stable.

[0017] 3. In this application, the use of the notched insertion cavity and the C-shaped elastic clamp allows for easy one-handed disassembly and assembly of the lamp head, making the lamp head disassembly and assembly process more convenient. The use of the elastic retaining clip can improve the vibration resistance of the vehicle lamp without affecting the one-handed disassembly and assembly of the lamp head. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0032] Example 1 refer to Figures 1 to 11 ,like Figures 1 to 9As shown, this embodiment provides a magnetic bicycle lamp holder. The lamp holder 2 includes a mounting part, a mating cavity 21, and a magnetic part 23. The mounting part is used to fix the lamp holder 2 to the corresponding mounting shaft 3 of the bicycle. The magnetic part 23 is used to provide magnetic attraction force. The mating cavity 21 is provided with an elastic retaining member 22. The magnetic attraction force of the magnetic part 23 is used to attract and insert the plug 11 of the lamp head into the mating cavity, making it easy to install and remove the lamp head 1. The elastic retaining member 22 is used to elastically engage with the annular groove 111 provided on the plug 11 of the lamp head 1. By providing the elastic retaining member 22, the installation stability of the lamp head 1 is improved, making the lamp head 1 less likely to fall off.

[0033] In this embodiment, the magnetic attraction part 23 is preferably a permanent magnet.

[0034] The lamp holder 2 can be configured in different structural forms depending on the installation location, such as... Figures 1 to 3 As shown, this structure is suitable for mounting the frame of a bicycle seat; as Figures 4 to 6 As shown, this structure is suitable for mounting the vertical beam of a bicycle; the lamp holder 2 can be installed by combining two semi-circular clamps, or by using cable ties 4 for binding and fixing.

[0035] In this embodiment, in order to make the lamp head 1 stick together stably, the magnetic suction part 23 is located at the bottom of the insertion cavity 21, so that the magnetic attraction force is concentrated and the magnetic attraction force is stable.

[0036] like Figure 8 and Figure 10 As shown, in this embodiment, the elastic clamping member 22 is preferably a C-shaped elastic clamp, which achieves the detachment of the lamp head 1 by outward expansion deformation. The C-shaped elastic clamp is not easily deformed and has good stability, thereby making the lamp holder 2 work stably.

[0037] When the insertion cavity 21 is a round hole, guide slopes can be provided on both sides of the elastic retaining member 22. The guide slopes allow the plug 11 to pass smoothly through the elastic retaining member 22, which facilitates the disassembly and assembly of the lamp holder 1 and ensures that the elastic retaining member 22 will not be damaged during the disassembly and assembly process.

[0038] In this embodiment, preferably, the side wall of the insertion cavity 21 has a notch that communicates with the outside. The opening of the elastic clamping member 22 corresponds to the position of the notch. When it is necessary to remove the lamp head 1, the elastic clamping member 22 can be opened by sliding the lamp head 1 to achieve separation. The lamp head 1 can be removed with one hand, which is convenient to use. During the removal of the lamp head 1, the force on the elastic clamping member 22 is only applied radially for expansion and deformation, and it is not easy to deform axially, so the working stability is good.

[0039] Since the lamp head 1 only needs to be moved radially when it is removed, in this embodiment, preferably, the outer side of the socket facing the insertion cavity 21 of the elastic retaining member 22 is provided with a guide slope, and the inner side of the elastic retaining member 22 is a radial plane. By setting the guide slope, it can be ensured that the plug 11 can be smoothly installed through the elastic retaining member 22. The inner side of the elastic retaining member 22 is a radial plane, so that the lamp head 1 cannot be pulled out directly along the axial direction, the locking is stable and not easy to disengage.

[0040] To improve the stability of the vehicle headlight, a spring-loaded retainer 24 is provided on the bottom of the insertion cavity 21, located within a notch. When the headlight 1 is in the installed state, the spring-loaded retainer 24 abuts against the outer periphery of the plug 11, preventing the headlight 1 from being violently vibrated and sliding out along the notch when the bicycle passes over mountainous or abnormally bumpy roads. The spring-loaded retainer 24 can be a spring-loaded arm that swings vertically relative to the bottom of the cavity. The side of the spring-loaded arm facing the plug 11 has a guide slope, which can ensure that the headlight 1 can smoothly pass over the spring-loaded retainer 24 when it is removed. The spring-loaded retainer 24 can also be a swing arm that is hinged by a torsion spring. The spring-loaded retainer 24 can also be a push arm that is pushed towards the plug 11 by a spring. The push arm moves backward to make room for the plug 11 to be pulled out, thus removing the headlight.

[0041] In this embodiment, in order to facilitate the replacement of the elastic clamping member 22 without affecting its function, the elastic clamping member 22 needs to be detachably installed. To facilitate the installation of the elastic clamping member 22, the elastic clamping member 22 has a C-shaped ring body for positioning and a plurality of locking teeth 221 provided on the C-shaped ring body that cooperate with the ring groove 111, and the guide slope is located on the locking teeth 221.

[0042] When the elastic retaining member 22 is integrally formed with the base of the lamp holder 2, the elastic retaining member 22 can be a C-shaped ring with a regular shape that is fixed in the center.

[0043] To prevent the lamp head 1 from shaking when subjected to vibration, a C-shaped retaining ring 231 is provided on the bottom of the insertion cavity 21, and the opening position of the retaining ring 231 corresponds to the notch position. The vibration of the lamp head 1 is reduced by the cooperation between the retaining ring 231 and the plug 11.

[0044] To facilitate the positioning of the elastic engaging member 22, the bottom of the insertion cavity 21 has a boss 232 that is fitted and installed with the elastic engaging member 22. The limiting ring 231 is located on the boss 232, and the locking tooth 221 is located outside the limiting ring 231.

[0045] like Figures 1 to 3 The lamp holder 2 shown is of the first structural form and as shown in the figure. Figures 4 to 6The lamp holder 2 shown in the first structural form is a structure in which the base, magnetic part 23, and elastic retaining member 22 are detachably assembled into one unit. To facilitate the limiting installation of the elastic retaining member 22, the base can be connected in two or three parts. The magnetic part 23 is installed on the base and located behind the insertion cavity 21. The base has a mounting part. The detachable assembly method of the lamp holder 2 makes it easy to disassemble and assemble, and facilitates the replacement of individual parts. In the first structural form of the lamp holder 2, the base includes a base and a cover that are connected as one unit. In the first type of lamp holder 2, a mating cavity 21 is formed between the base and the cover, and the elastic retaining member 22 is limited between the base and the cover. The mounting part is located on the base or the cover. In the second type of lamp holder 2, the base includes a front cover and a rear seat that fit together. A mating cavity 21 is formed between the front cover and the rear seat. The magnetic part 23 is installed in the base. The elastic retaining member 22 is limited between the front cover and the rear seat. The rear seat of the base abuts against the vertical beam. The front cover of the base is provided with a pull groove that cooperates with the cable tie 4. The pull groove is used to make the front cover abut against the rear seat and the rear seat abut against the vertical beam, making the lamp holder 2 easier to disassemble and assemble, and less likely to cause damage to the parts during disassembly and assembly.

[0046] Example 2 Based on the magnetic bicycle lamp holder disclosed in Embodiment 1, this application discloses another technical solution: a bicycle lamp including the magnetic bicycle lamp holder described in Embodiment 1, and further including a lamp head 1. The back of the lamp head 1 has a plug 11, which is T-shaped and forms an annular groove 111 extending to the lamp body of the lamp head 1. The plug 11 is provided with a plug guide cone surface 112, which facilitates automatic guidance and alignment during the plugging process, making the installation process of the lamp head 1 smooth.

[0047] In this embodiment, the limiting ring 231 has a tapered hole that mates with the insertion guide tapered surface 112, which facilitates the stable entry of the plug 11 into the limiting ring 231.

[0048] When the lamp holder 1 and the lamp base 2 are assembled, the lamp holder 1 is pushed along the axial direction and the plug 11 is inserted into the mating cavity 21 by using magnetic attraction force, and the elastic clamping part 22 automatically clamps with the annular groove 111; when the lamp holder 1 and the lamp base 2 are separated, the lamp holder 1 is pushed to move radially and slide out along the notch, which is convenient to operate and stable to use.
