[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 and Figure 2 An embodiment of the utility model provides a synchronously adjustable portable tool light, which includes a base 10 and a plurality of lamp bodies 20, wherein the base 10 includes a plurality of cabins 11 formed on the surface for accommodating the lamp bodies, each of the cabins 11 is provided with an electrical contact 12, and each of the electrical contacts 12 is electrically connected to each other.

[0027] Each lamp body 20 includes a lamp body controller U2, an electrical connector 21, a light source 22 and a switch module SW1. The switch module SW1, the light source 22 and the electrical connector 21 are all electrically connected to the lamp body controller U2, and the electrical connector 21 is configured to form an electrical connection with the electrical contact 12 when the lamp body 20 is accommodated in the cabin 11.

[0028] In this embodiment, specifically, Figure 1 The base 10 is formed with three cabins 11, which means that it can accommodate up to three lamp bodies 20. The cabins 11 may be arranged in parallel or at a certain angle (such as forming a triangle), which is not specifically limited in the present invention.

[0029] In this embodiment, in particular, the lamp body controller U2 can be a single chip microcomputer of model CMS79FT623B. Of course, other models can also be selected according to actual needs, and the utility model does not make specific limitations.

[0030] In this embodiment, in particular, the electrical contact 12 is a contact pin, which is located on the side wall of the cabin 11 and relatively protrudes from the surface of the cabin 11, and the electrical connection piece 21 is a contact piece.

[0031] In this embodiment, in particular, the electrical contact member 12 and the electrical connection sheet 21 may be made of a material having conductive properties such as nickel or copper.

[0032] In this embodiment, in particular, the lamp body 20 also includes a power source (such as a battery); the electrical connector 21 includes four contacts, the four contacts include a first contact connected to the positive electrode of the power source, a second contact connected to the negative electrode of the power source, and a SDA pin (i.e., Figure 2 The third contact connected to the pin 16 in the lamp body and the SCL pin of the lamp body controller (i.e. Figure 2 The fourth contact connected to pin 14) in.

[0033] In this embodiment, the electrical contact 12 includes four contact pins corresponding to the four contact pieces. In this way, when multiple lamp bodies 20 are placed in the cabin 11, based on the connection between the electrical contact 12 and the electrical connector 21, and the connection between the electrical contact 12 of each lamp body 20, each lamp body 20 can be connected to the electrical connector 21 through I 2 C to communicate.

[0034] In this embodiment, the switch module SW1 is electrically connected to the key function pin (ie Figure 2 pin 15 in the

[0035] When multiple lamp bodies 20 are placed on the base 10, when the switch module SW1 of a lamp body 20 is operated, the operation is received by the lamp body controller U2 through the key function pin and a corresponding operation signal is generated. The operation signal controls the light source 22 of the lamp body 20 to change its working state, such as changing its working brightness or on / off state; on the other hand, the operation signal is used to control the light source 22 of the lamp body 20 to change its working state, such as changing its working brightness or on / off state; 2 C is sent to other lamp bodies 20 through the electrical connector 21 and the electrical contact 12. After receiving the operation signal, other lamp bodies 20 check their own working states. If they are inconsistent with the operation signal, they change their own working states, so that the working states of all lamp bodies 20 are consistent, that is, the synchronous adjustment of the working states of multiple lamp bodies 20 is achieved.

[0036] For example, a lamp has four different brightness levels: high, medium, low and off. The brightness of the first lamp is high, the second lamp is low, the third lamp is medium and the fourth lamp is off. If you want to adjust the brightness of all lamps to high, the prior art requires adjusting each lamp separately.

[0037] For example, the first lamp is on, the second lamp is off, the third lamp is off, and the fourth lamp is on. If you want to adjust all lamp states to bright, you need to adjust the second and third lamps.

[0038] In this embodiment, only the brightness of one lamp body needs to be adjusted to achieve state synchronization of all lamp bodies. Taking the first example, the lamp body has four different brightness levels of high, medium, low and off, and the brightness of the first lamp body is high, the second lamp body is low, the third lamp body is medium, and the fourth lamp body is off. At this time, if you want to adjust the brightness of all lamp bodies to high, you can adjust the brightness of any of the four lamp bodies to high, and the working state of high brightness will be automatically synchronized to other lamp bodies, so that the brightness of all lamp bodies is high.

[0039] In summary, this embodiment increases the communication between different lamp bodies 20, so that when the working state of a lamp body 20 changes, the changed working state can be transmitted between the lamp bodies 20, thereby synchronizing the working states of the lamp bodies 20. Compared with the prior art, this embodiment only needs to operate one lamp body 20 to synchronize the working states of all lamp bodies, which greatly simplifies the user's operation and provides a good user experience.

[0040] Some preferred embodiments of the present utility model are further described below.

[0041] On the basis of the above embodiments, in a preferred embodiment of the present invention:

[0042] The light source 22 is connected to the PWM pin of the lamp controller through two parallel first MOS tubes Q1 and second MOS tubes Q2 ( Figure 2 Pin 3 in the figure); wherein the PWM pin is connected to the gates of the first MOS tube Q1 and the second MOS tube Q2 respectively, the sources of the first MOS tube Q1 and the second MOS tube Q2 are grounded, and the drains of the first MOS tube Q1 and the second MOS tube Q2 are connected to the light source 22.

[0043] In this embodiment, the MOS tube can be an N MOS tube, and the PWM pin sends a PWM signal to the two MOS tubes, wherein the MOS tube is turned on when the PWM signal is at a high level, and the MOS tube is turned off when the PWM signal is at a low level. The duty cycle of the high level is high, and the brightness of the light source 22 is high. The duty cycle is low, and the brightness of the light source 22 is relatively reduced. When the duty cycle is 0, it corresponds to a low level, and the lamp body 20 is turned off.

[0044] In this embodiment, the design of connecting the first MOS transistor Q1 and the second MOS transistor Q2 in parallel can improve the overall heat dissipation effect of the circuit.

[0045] Specifically, MOS tubes connected in parallel can reduce the on-resistance of each MOS tube, thereby improving the efficiency of the entire circuit. Especially in high-power applications, reducing the on-resistance can reduce power consumption and reduce the heat generated, thereby achieving better heat dissipation effects.

[0046] On the basis of the above embodiments, in a preferred embodiment of the present invention:

[0047] like Figure 2 As shown, pin 1 (TX pin) and pin 2 (RX pin) of the lamp controller U2 are program burning pins, which are used to connect to the burning port. Pins 4, 5, and 6 are connected to the LED indicator light, which is used to display the power of the power supply; pins 7 and 8 are the ground and power supply of the lamp controller U2 respectively; pin 9 is the AD sampling pin, which is used to detect whether the LED indicator light is short-circuited, which plays a protective role; pins 10 and 13 detect the current voltage of the power supply through resistor voltage division; pins 11 and 12 are charging circuit status detection pins, which detect the charging status.

[0048] like Figure 3 As shown, based on the above embodiments, in a preferred embodiment of the present utility model:

[0049] The lamp body 20 includes a shell 23, a lens is embedded on one side of the shell 23, the light source 22, the lamp body controller U2, and the power supply are all arranged in the shell, and the switch module SW1 and the electrical connector 21 are relatively exposed on the surface of the shell 23; the shell 20 has a recessed cavity for accommodating a rotating bracket 25, and the rotating bracket 25 is placed in one end of the recessed cavity and connected to the shell 20 through a rotating shaft.

[0050] In this embodiment, since the rotating bracket 25 can rotate relative to the housing 23, the lighting direction can be adjusted by rotating the bracket 25 to meet different lighting requirements.

[0051] Furthermore, a magnet 24 is also provided on the rotating bracket 25 .

[0052] In this embodiment, considering that portable lamps generally work in areas with complex environments, such as construction sites, under vehicles, etc., the combination of the rotating bracket 25 and the magnet 24 can better fix the portable lamp in various complex environments, thereby facilitating user operation.

[0053] Furthermore, the rotating bracket 25 is placed at one end of the recessed cavity to form a plurality of spaced protrusions 251, and the outer shell 23 is formed with an elastic member 26 corresponding to one end of the rotating bracket 25, and the elastic member 26 is configured to form elastic contact with the protrusion 251 of the rotating bracket 25 when the rotating bracket 25 rotates around the rotating axis.

[0054] Specifically, the elastic member 26 may include a spring 261 and a connecting block 262. During the rotation of the rotating bracket 25, one end thereof will be in elastic contact with the connecting block 262. Since a plurality of spaced protrusions 251 are formed at one end of the rotating bracket 25, when the protrusions 251 contact the connecting block 262, a large downward pressure will be exerted on the spring 261, causing the spring 261 to form a large deformation. When the two protrusions 251 contact the connecting block 262, a small pressure will be exerted on the spring 261, causing the spring 261 to form a small deformation. In this way, the deformation change of the spring 261 makes the rotating bracket 25 produce a gear sense during the rotation process, thereby improving the user's operating experience.

[0055] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
