Description

Technical Field

[0001] This utility model relates to the field of TD technology, and in particular to a headlamp whose protective cover can be folded horizontally to the top by elastic pulling. Background Technology

[0002] A headlamp, as the name suggests, is a light worn on the head, a hands-free lighting tool. It typically consists of a headband, lamp head, battery, and control switch. Its core design principle is to fix the light source to the head, achieving hands-free illumination. Its advantages include comfortable wear and high portability, making it widely applicable in outdoor adventures, night cycling, camping and hiking, cave exploration, construction site work, and other scenarios. It is especially indispensable in environments requiring two hands or with insufficient light.

[0003] When engaging in outdoor activities, headlamps are worn on the user's head, making them unable to see the headlamp in their line of sight. This can easily lead to the headlamp being overlooked. While this is less common when the headlamp is on for illumination, it is more susceptible to collisions with objects when the headlamp is off and still worn on the head. Since headlamps typically have transparent glass covers, these can break upon impact, affecting the lighting effect. Currently, to protect the headlamp cover when not in use, a protective cover is usually designed into the headlamp design. This cover can be removed when illumination is needed. Existing protective covers come in two types: one uses a rope to connect the cover, allowing it to remain suspended on the headlamp even after removal, preventing loss; however, this method results in the cover swaying back and forth when the user moves, affecting lighting performance and even the user's vision; the other uses a hinge and torsion spring, where the torsion spring's pre-stored energy causes the cover to flip when the user opens it. However, the flipping angle is limited, causing the cover to stand vertically on top of the headlamp after being opened, increasing the overall size of the headlamp. In outdoor spaces with limited space, the top cover is easily damaged by collisions with external objects.

[0004] In conclusion, existing headlamps still have some shortcomings in terms of lampshade protection. Therefore, it is necessary to propose a new technical solution to address these issues. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a headlamp in which the protective cover is folded horizontally to the top by elastic pulling, comprising a shell, wherein the shell is provided with a wearing surface and a lighting surface, the wearing surface is provided with a strap, and the lighting surface is provided with a lampshade;

[0007] The housing contains a circuit board and a power supply module electrically connected to the circuit board. The circuit board has LED beads, and the lampshade acts on the LED beads.

[0008] A protective cover acting on the lampshade is provided on the lighting surface. The upper surface of the outer shell is provided with symmetrically arranged slide bars. Each of the two slide bars has a groove on one side opposite to the lighting surface. The slide bars and grooves protrude towards the lighting surface. Rotating rods are provided on both sides of the upper end of the protective cover. The rotating rods slide in the grooves. A fixing plate is provided on the upper end of the outer shell near the wearing surface. A contraction spring is connected to the fixing plate and is connected to the upper end of the protective cover.

[0009] The lighting surface of the outer casing is also provided with a locking mechanism for securing the protective cover.

[0010] As a further embodiment of this utility model: the locking mechanism includes a locking groove formed on the lighting surface, damping rubber blocks are provided on both sides inside the locking groove, and a limiting groove is provided between the lower end of the damping rubber block and the bottom wall of the locking groove;

[0011] The locking mechanism also includes a round rod disposed at the lower end of the protective cover, and a limit block is provided at the lower end of the round rod;

[0012] The distance between the two damping blocks is less than the diameter of the round rod, and the two damping blocks have an arc-shaped groove formed on the opposite side. The round rod is squeezed into the space between the two damping blocks and fits into the arc-shaped groove. At the same time, the limiting block and the limiting groove are interlocked.

[0013] As a further embodiment of this utility model: a first hook is provided on the fixing plate, a second hook is provided on the upper end of the protective cover, and the two ends of the retraction spring are respectively fixed to the first hook and the second hook.

[0014] As a further embodiment of this utility model: an upper cover plate is provided between the two slide bars, and the retraction spring is located between the upper cover plate and the top wall of the outer shell.

[0015] As a further embodiment of this utility model: the end of the slide bar protruding from the lighting surface extends downward to form a vertical part, and the slide groove extends downward to form a vertical groove corresponding to the vertical part. After the protective cover is rotated downward to the vertical state, it can be moved downward to move the rotating rod to the vertical groove, so that the second hook is flush with the first hook.

[0016] As a further embodiment of this utility model: a magnetic attractor is provided on the side wall of the slide away from the lighting surface, and a magnetic block that can be magnetically attracted to the magnetic attractor is provided at the upper end of the rotating rod.

[0017] As a further embodiment of this utility model, a cover plate is also provided at the lower end of the protective cover.

[0018] As a further embodiment of this utility model, the circuit board is also provided with a start button and a charging interface that are visible through the surface of the outer casing.

[0019] Compared with the prior art, the beneficial effects of this technical solution are as follows: When lighting is required, the protective cover used to protect the lampshade on the lighting surface is opened and rotated upwards. The protective cover rotates with the rotating rod at its upper end as the axis, and the rotating rods at both ends can be slidably set in the sliding groove of the slide bar. When the protective cover rotates 90° to a parallel state, the retraction spring on the fixing plate will pull the protective cover to the upper end of the outer shell. With the setting of the sliding groove, the protective cover can move horizontally at this time and be horizontally folded with the upper end of the outer shell. This can quickly open the protective cover to allow the headlamp to illuminate normally, and fix the protective cover in the horizontally folded state on the top of the outer shell, which can avoid the protective cover affecting the lighting effect of the headlamp and prevent the protective cover from being damaged by collision with external objects.

[0020] When the protective cover needs to be put back on to protect the lampshade, pull the protective cover on the top of the outer shell toward the lighting surface. While pulling, the spring will be stretched and contracted. When the rotating rod at the top of the protective cover moves to the position where the slide bar and slide groove protrude toward the lighting surface, the protective cover will be rotated downward and fixed by the locking mechanism. This allows the protective cover to be folded vertically with the lighting surface and cover the lampshade to prevent the lampshade from being hit.

[0021] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-7 A headlamp that can be folded horizontally to the top by elastic pulling includes a housing 1, the housing 1 is provided with a wearing surface 11 and a lighting surface 12, the wearing surface 11 is provided with a strap 2, and the lighting surface 12 is provided with a lampshade 3.

[0034] The outer casing 1 contains a circuit board 4 and a power supply module 5 electrically connected to the circuit board 4. The circuit board 4 is equipped with LED beads 6, and the lamp cover 3 acts on the LED beads 6.

[0035] A protective cover 7 acting on the lampshade 3 is provided on the lighting surface 12. A symmetrically arranged slide bar 8 is provided on the upper end surface of the outer shell 1. A slide groove 81 is provided on each side of the two slide bars 8. The slide bar 8 and the slide groove 81 protrude towards the lighting surface 12. A rotating rod 71 is provided on both sides of the upper end of the protective cover 7. The rotating rod 71 is slidably engaged in the slide groove 81. A fixing plate 9 is provided on the side of the upper end of the outer shell 1 near the wearing surface 11. A contraction spring 91 is connected to the fixing plate 9. The contraction spring 91 is connected to the upper end of the protective cover 7.

[0036] The lighting surface 12 of the outer casing 1 is also provided with a locking mechanism 10 for fixing the protective cover 7.

[0037] Specifically, when lighting is required, the protective cover 7 on the lighting surface 12, which protects the lampshade 3, is opened and rotated upwards. The protective cover 7 rotates around the pivot 71 at its upper end, and both pivots 71 at both ends are slidably fitted into the grooves 81 of the slide bar 8. When the protective cover 7 rotates 90° to a parallel state, the retraction spring 91 on the fixing plate 9 pulls the protective cover 7 towards the upper end of the outer shell 1. With the help of the grooves 81, the protective cover 7 can move horizontally and fold horizontally with the upper end of the outer shell 1. This allows the protective cover 7 to be quickly opened to allow the headlamp to illuminate normally, and also allows the protective cover 7 to be fixed to the top of the outer shell 1 in a horizontally folded state. This prevents the protective cover 7 from affecting the lighting effect of the headlamp and prevents the protective cover 7 from being damaged by collision with external objects, thus extending its service life.

[0038] The user can put the strap 2 on the head through the wearing surface 11. The strap 2 is an elastic band that can be fixed to the user's head by elastic contraction. The fixing and adjustment of the strap 2 are existing mature technologies, which will not be described in detail here.

[0039] When the protective cover 7 needs to protect the lampshade 3 again, pull the protective cover 7 on the top of the outer shell 1 toward the lighting surface 12. While pulling, the spring 91 will be stretched. When the rotating rod 71 at the upper end of the protective cover 7 moves to the position where the slide bar 8 and the slide groove 81 protrude toward the lighting surface 12, the protective cover 7 is rotated downward and fixed by the locking mechanism 10. This allows the protective cover to be folded vertically with the lighting surface 12 and cover the lampshade 3 to prevent the lampshade 3 from being hit.

[0040] refer to Figure 5 and Figure 7 Based on the above embodiments, it is further proposed that the locking mechanism 10 includes a locking groove 101 opened on the lighting surface 12, and damping rubber blocks 102 are provided on both sides inside the locking groove 101. A limiting groove 103 is provided between the lower end of the damping rubber block 102 and the bottom wall of the locking groove 101.

[0041] The locking mechanism 10 also includes a round rod 104 disposed at the lower end of the protective cover 7, and a limit block 105 is provided at the lower end of the round rod 104;

[0042] The distance between the two damping blocks 102 is smaller than the diameter of the round rod 104, and the two damping blocks 102 have an arc groove 106 formed on the opposite side. The round rod 104 is squeezed into the space between the two damping blocks 102 and fits into the arc groove 106. At the same time, the limiting block 105 and the limiting groove 103 are interlocked.

[0043] Specifically, during the process of rotating the protective cover 7 downwards to cover the lampshade 3 and folding it with the lighting surface 12, the round rod 104 causes the two damping rubber blocks 102 to deform by compression, thereby allowing the round rod 104 to enter the interior through the gap between the two damping rubber blocks 102. After the round rod 104 enters the interior, the two damping rubber blocks 102 elastically recover, so that the inner wall of the arc groove 106 fits against the round rod 104, thereby restricting the outward rotation of the round rod 104. At the same time, the limiting block 105 at the lower end of the round rod 104 and the limiting groove 103 are interlocked. The limiting groove 103 is formed between the damping rubber block 102 and the bottom wall of the locking groove 101, thereby restricting the up and down movement of the protective cover 7. Through the above structure, the protective cover 7 can be fixed when it vertically covers the lampshade 3, preventing the protective cover 7 from rotating and moving upwards due to the pull of the contraction spring 91.

[0044] When it is necessary to remove the protective cover 7, rotate the protective cover 7 upwards and apply a force that can deform the damping rubber block 102, so that the round rod 104 can be disengaged from the two damping rubber blocks 102. Then the protective cover 7 can be rotated, and the spring 91 will be contracted to pull the protective cover 7 to the top of the outer shell 1.

[0045] Preferably, two round rods 104 are provided, located on both sides of the lower end of the protective cover 7, and two locking grooves 101 are also provided, corresponding to the positions of the two round rods 104 respectively, to ensure that the protective cover 7 is securely locked.

[0046] The damping rubber block 102 is preferably made of silicone material.

[0047] refer to Figure 5 Based on the above embodiments, it is further proposed that a cover plate 72 is provided at the lower end of the protective cover 7. The cover plate 72 can facilitate the user to open the protective cover 7 and to pull the protective cover 7 stored on the top of the outer shell 1 outward.

[0048] refer to Figures 3-5 Based on the above embodiments, it is further proposed that a first hook 92 is provided on the fixing plate 9, a second hook 73 is provided on the upper end of the protective cover 7, and the two ends of the retraction spring 91 are respectively fixed to the first hook 92 and the second hook 73.

[0049] Specifically, the two ends of the retraction spring 91 are connected by a first hook 92 and a second hook 73. The design of the first hook 92 and the second hook 73 can prevent the retraction spring 91 from being twisted when the protective cover 7 is rotated.

[0050] refer to Figure 1-3 Based on the above embodiments, it is further proposed that an upper cover plate 84 is provided between the two slide bars 8, and a contraction spring 91 is located between the upper cover plate 84 and the top wall of the outer shell 1.

[0051] Specifically, the upper cover plate 84 is used to cover the retraction spring 91 to protect it and prevent it from being caught on external objects, which could cause it to detach or be damaged. For example, in an outdoor jungle, this can prevent the spring from being hooked by tree branches.

[0052] refer to Figure 2 and Figure 6 Based on the above embodiments, it is further proposed that the end of the slide bar 8 protruding from the lighting surface 12 extends downward to form a vertical part 82, and the slide groove 81 extends downward to form a vertical groove 83 corresponding to the vertical part 82. After the protective cover 7 is rotated downward to the vertical state, it can be moved downward to move the rotating rod 71 to the vertical groove 83, so that the second hook 73 is flush with the first hook 92.

[0053] Specifically, by setting the vertical part 82 and the vertical groove 83, after the protective cover 7 is rotated to a vertical state, the second hook 73 at the top is flush with the first hook 92, so that the retraction spring 91 between the first hook 92 and the second hook 73 remains parallel. This can prevent the retraction spring 91 from hitting the upper cover plate 84, which would cause structural conflict, and prevent the retraction spring 91 from undergoing different deformations.

[0054] refer to Figures 5-6 Based on the above embodiments, it is further proposed that a magnetic attractor 85 is provided on the side wall of the slide 81 away from the lighting surface 12, and a magnetic block 74 is provided at the upper end of the rotating rod 71 that can be magnetically attracted to the magnetic attractor 85.

[0055] Specifically, after the protective cover 7 is rotated and then pulled into the top of the outer shell 1 by the retraction spring 91, the magnetic block 74 on the rotating rod 71 will attract each other with the magnetic suction piece 85 in the slide groove 81, thereby keeping the protective cover 7 on the top of the outer shell 1 and preventing the protective cover 7 from being moved laterally due to inertia caused by vibration or sudden stop when the user moves it. The magnetic suction piece 85 is preferably a magnet, and the magnetic block 74 is preferably an iron block.

[0056] refer to Figure 3 Based on the above embodiments, it is further proposed that the power supply module 5 is a lithium battery and is electrically connected to the circuit board 4 to supply power to the LED beads 6;

[0057] Furthermore, the circuit board 4 is also provided with a start button 41 and a charging interface 42 that are exposed on the surface of the housing 1. The start button 41 can control the lamp beads 6 to turn on and off, and the charging interface 42 can charge the power supply module 5.

[0058] Among them, LED lamp beads are preferred for lamp beads 6.

[0059] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
