Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

as shown in fig. 1 to 9, the working lamp in this embodiment includes a housing 1, a cover plate 2 and a handle 3, a light emitting assembly 4 is disposed in the housing 1, two ends of the handle 3 are respectively rotatably connected to the housing 1, a damping hinge structure 5 is disposed on the housing 1, the damping hinge structure 5 has a positioning tooth slot portion 6, one end of the handle 3 has a positioning tooth portion 7 in sleeve fit with the positioning tooth slot portion 6 of the damping hinge structure 5, and the end of the handle 3 having the positioning tooth portion 7 is hinged to the housing 1 through the positioning tooth portion 7 and the positioning tooth slot portion 6 in sleeve fit. The cover plate 2 may be formed with an opening 20 so that the light emitting portion of the light emitting element 4 can emit light outwardly at the opening 20.

referring to fig. 3, 4 and 6, in the present embodiment, one end of the handle 3 may have a protrusion 8, the positioning tooth portion 7 is formed on the periphery of the protrusion 8, the positioning tooth portion 7 has a plurality of teeth 70, the positioning tooth portion 6 has a slot 60 and a plurality of positioning grooves 61 formed on the inner wall of the slot 60 and cooperating with the corresponding teeth, and the protrusion 8 is fitted into the slot 60 such that the teeth 70 of the positioning tooth portion 7 are engaged with the positioning grooves 61 of the positioning tooth portion 6. That is, each tooth 70 of the positioning tooth portion 7 needs to have a positioning groove 61 corresponding to it, so as to ensure that each tooth of the positioning tooth portion 7 can be snapped into the corresponding positioning groove. Wherein, referring to fig. 7, the edge of the slot 60 forms a regular polygon with at least four sides to ensure that the handle can be turned up or pressed down even if the positioning teeth 7 and the positioning teeth 6 are in a nested state. In this embodiment, the edges of the slot 60 form a regular octagon to ensure that the tab 8 can be rotated progressively within the slot 60. Of course, the edges of the slot 60 may form other regular polygons with more than four sides. For example, the tooth portion 7 has eight teeth 70, and the positioning tooth portion 6 has eight positioning grooves 61, so that each tooth 70 is engaged with one positioning groove 61. Once the handle is turned up, each tooth on the tooth part 70 will shift, and then the tooth enters into the next positioning groove adjacent to the original positioning groove in sequence, and the positioning tooth part and the positioning groove at this moment will be clamped together, so that the end of the handle cannot easily rotate upwards or downwards relative to the shell without receiving external force, and the positioning of the handle state under the state by using the damping hinge structure is achieved.

Specifically, when the handle 3 is turned upwards to an angle, one tooth on the positioning tooth part 7 is clamped into the corresponding positioning groove 61 of the positioning tooth groove part 6, and other teeth and the positioning grooves are mutually matched and clamped together, so that an angle is formed between the handle and the upper surface of the shell at the moment, and the handle can maintain the turning-up state corresponding to the current angle under the action of damping force; if the handle 3 is turned upwards, another larger angle is formed between the handle 3 and the upper surface of the shell, and the handle 3 maintains the turning-up state corresponding to the larger angle under the damping force.

Because one end of the handle 3 is hinged with the shell 1 and the other end of the handle is rotationally connected to the shell 1, when a user holds the handle of the work light and turns upwards, the positioning convex tooth part 7 on the handle 3 can be clamped with the positioning tooth groove part 6 of the damping hinge structure 5, and the handle 3 cannot be directly turned up but slowly faces away from the surface of the shell to be turned up because the handle is influenced by the damping force of the damping hinge structure 5, namely, the angle between the handle 3 and the surface of the shell 1 is slowly and gradually increased, so that the effect that the handle is gradually and gradually turned upwards is achieved, and the situation that the handle of the traditional work light cannot be positioned and fixed in each turning-up state of the handle because the handle is easily turned up is avoided. Of course, the handle 3 in the turned-up state can be turned down again gradually and gradually toward the housing 1 by adopting the reverse operation mode, and the state positioning of the handle 3 at each turned-up angle is realized.

Referring to fig. 7 and 8, in the damping hinge structure, a circular groove 50 is formed on the damping hinge structure 5 of the present embodiment, and a wire loop 51 disposed along the circular groove direction and capable of generating a frictional force with the bottom wall of the circular groove 50 is provided in the circular groove 50. When a user turns up the handle, the wire loop 51 positioned in the circular groove 50 is stressed through the matching of the positioning convex tooth part 7 on the handle and the positioning tooth groove part 6, so that the wire loop 51 is contracted towards the bottom wall direction of the circular groove 50, further, the wire loop 51 generates friction force with the bottom wall of the circular groove 50, and then the generated friction force generates damping force influence on the turning handle, and the damping effect on the turning handle is achieved. The wire loop 51 of the present embodiment may be a wire rod having a circular arc section, the circular arc section is matched with the circular groove 50 and is placed in the circular groove 50, and both ends of the wire rod are fixed on the housing 1.

In particular, the damping hinge structure 5 may be fixed to the housing by providing a first limiting groove 9 on the housing 1, and the damping hinge structure 5 is installed in the first limiting groove 9, so that the end of the handle 3 (i.e. the end having the positioning convex tooth portion 7) can be hinged to the housing 1. Referring to fig. 5, correspondingly, in consideration of the overall volume of the damping hinge structure 5 to ensure that the damping hinge structure can be properly placed in the space formed by the housing and the cover plate, a first engaging groove 21 corresponding to the first limiting groove 9 may be formed on the back surface of the cover plate 2. That is, after the cover plate 2 is fastened to the housing 1, the damping hinge structure 5 is limited and fixed in the space formed by the first limiting groove 9 and the first matching groove 21.

As another fixing mode between the handle 3 and the housing 1, referring to fig. 3 and 4, a second limiting groove 10 may be further disposed on the housing 1, and the other end of the handle 3 has a rotating protrusion 11 capable of entering the second limiting groove 10 to realize rotation. With this arrangement, one end of the handle 3 can be hinged to the housing 1, and the other end of the handle 3 can be rotatably connected to the housing 1 by the engagement between the rotation protrusion 11 and the second limiting groove 10. Similarly, a second engaging groove 22 corresponding to the second limiting groove 10 may be further formed on the back surface of the cover plate 2, so that the rotating protrusion 11 at the other end of the handle is limited in the space formed by the second limiting groove 10 and the second engaging groove 22.

It should be added that, in order to enhance the hinge effect between the handle 3 and the housing 1, as shown in fig. 10, two damping hinge structures 5 may be oppositely disposed on the housing 1, two first limiting grooves 9 are respectively disposed on the housing 1, two ends of the handle 3 are respectively provided with a positioning convex tooth portion 7 which is matched with a positioning tooth groove portion of the corresponding damping hinge structure, and the handle 3 and the housing 1 are hinged together through the positioning convex tooth portion and the positioning tooth groove portion which are correspondingly matched in a sleeved manner. That is, one damping hinge structure 5 of the housing 1 is fitted into one first stopper groove 9, and the other damping hinge structure 5 of the housing 1 is fitted into the other first stopper groove 9. Therefore, when the handle is held and turned over by a user, the whole handle can be influenced by the damping of the two damping hinge structures 5, so that the state positioning effect of the handle in various states can be further ensured, the handle is not easily turned over or buckled downwards, and the stable positioning requirement of the handle 3 in the corresponding actual state when the handle is turned upwards or pressed downwards for a certain angle is met. Correspondingly, the handle structure at this time is shown in fig. 11.

Of course, the casing 1 may also be provided with a corner protection structure 12 for protecting the corners of the casing, so as to prevent the corners of the casing from being damaged due to the influence of external force.

The housing 1 of this embodiment is further provided with a switch 13 for controlling the operation of the light emitting component, the bottom of the housing 1 is provided with a battery compartment 14 and an opening 15 for exposing the switch, and the outside of the battery compartment 14 is provided with a battery compartment cover 16. The operation light can start the illumination operation after the battery is mounted in the battery compartment 14 and the switch 13 is turned on. A battery compartment cover 16 is removably secured to the outside of the battery compartment 14 to enclose the batteries within the battery compartment 14. A heat sink 17 may be disposed below the light emitting component 4 to dissipate heat generated during operation of the light emitting component in a timely manner.

In order to satisfy the requirement of stably placing the work light on the surface of the vehicle-mounted iron component, a magnet 18 may be further provided on the outer side surface of the bottom of the housing 1 to stably attract the entire work light to the vehicle by the attraction force between the magnet 18 and the vehicle-mounted iron component. Wherein the magnet 18 is embedded in the bottom of the housing 1. The number of the magnets embedded in the bottom of the shell can be set to be a plurality according to needs, so that the stability of the work light when the work light is fixed on the surface of the iron part is enhanced.
