[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0025] like Figure 1 and 2 As shown, a battery pack 100 with auxiliary functions in an embodiment of the utility model includes a housing 10 and a functional module 20. The interior of the housing 10 is used to install the battery. The functional module 20 is installed on the surface of the housing 10 and connected to the internal battery. It includes a projection device 21 capable of projecting light. The projection device 21 in this embodiment includes a laser projection component for projecting a scale.

[0026] In the above embodiment, in addition to supplying power, the battery pack 100 can also provide the auxiliary function of projecting a scale, which increases the functional attributes of the battery pack 100. Since the projection device 21 is directly connected to the battery in the battery pack, the above auxiliary functions can be provided when the battery pack is not installed on the tool, which has high flexibility.

[0027] Preferably, the projection device 21 may also include a laser distance measuring component, which is used to provide a distance measuring function for the battery pack 100, thereby further improving the functionality of the battery pack 100. The laser distance measuring component can cooperate with the laser projection component, and change the spacing between the scales projected by the laser projection component according to the data measured by the laser distance measuring component, so that when the distance from the battery pack 100 to the projection surface is changed, it can be adaptively adjusted to the correct scale size.

[0028] It is easy to imagine that the projection device 21 can also be a projection lamp or other lighting device, which is used to provide lighting or other auxiliary functions when the staff is operating, thereby improving the functionality of the battery pack 100.

[0029] In one embodiment, the laser projection assembly and the laser distance measuring assembly are arranged on the same side or two adjacent sides of the housing 10. When arranged on different sides, the laser distance measuring assembly can not only measure the distance of one side of the laser projection assembly, but also measure the distance of one side of itself, so it can cope with more complex usage scenarios with high flexibility.

[0030] Furthermore, in order to improve the flexibility during work, the projection angle of the projection device 21 is adjustable. In one embodiment, the projection angle of the projection device 21 is adjusted up and down to adjust the projection position on the workpiece surface. Of course, the projection angle of the projection device 21 can also be set to be adjusted left and right to cope with more complex usage scenarios, or when the projection is in the same direction but a certain angle offset is required.

[0031] In one embodiment, the projection device 21 is disposed near the bottom of the housing 10. Of course, in other embodiments, the projection device 21 may also be disposed at other positions on the housing 10, such as disposing projection devices 21 for different purposes at positions of different heights.

[0032] In one embodiment, the functional module 20 also includes an interactive button 22, which is arranged on the shell 10 and connected to the internal battery and the projection device 21, and is used to control the switch, projection angle, brightness, projection content or other working states of the projection device 21, such as movement and rotation of the projection scale.

[0033] Furthermore, the functional module 20 may also include a screen 23 disposed on the housing 10, which is connected to the internal battery, the interactive button 22 and the projection device 21, and can intuitively display information such as the remaining battery power, the working status of the projection device 21, and the like.

[0034] In one embodiment, the screen 23, the interactive button 22, and the projection device 21 are disposed on the same side surface or different side surfaces of the housing 10. Figure 1 In the figure, the projection device 21 is arranged at the front end of the shell 10 (the working direction of the power tool), and the screen 23 and the interaction button 22 are arranged on the side of the shell 10. The operator can obtain information from the screen 23 while operating the interaction button 22.

[0035] It should be understood that, in addition to the situations described above, the functional module 20 may also be configured to provide a structure that can provide other auxiliary functions such as a level gauge, so as to further improve the functionality of the battery pack 100 .

[0036] In a preferred embodiment, the housing 10 includes a first housing 11 and a second housing 12, which are detachably fixed, wherein the first housing 11 is used to install the battery and is connected to the main body of the power tool, and the second housing 12 is used to carry the functional module 20, and the functional module 20 enters the working state after the two parts are fixed. After adopting the above two-stage connection method, other functional modules 20 in addition to the above functions can be designed in the second housing 12, so that they can be replaced in time when different auxiliary functions are needed, which is more flexible.

[0037] exist Figure 1 In the embodiment shown, the two parts of the housing 10 are arranged up and down, and this arrangement is mainly used for power tools with batteries arranged at the bottom. It is easy to imagine that the positions of the two parts can also be adjusted to correspond to power tools with different installation positions, such as power tools that need to install the battery at the top or side of the tool.

[0038] Therefore, the battery pack 100 with auxiliary functions can provide different auxiliary functions for the electric tool, and at the same time it itself can also become an independent auxiliary tool, which can provide auxiliary functions from different directions when working, so it can also get rid of some other auxiliary tools and reduce the number of tools carried.

[0039] like Figure 3 As shown, the utility model also provides an electric tool 200, including a housing, a motor, a transmission device, an output shaft and the above-mentioned battery pack 100. The housing is formed with a receiving cavity, the motor is arranged in the receiving cavity, and is used to provide rotational power; the transmission device is at least partially (or entirely) arranged in the receiving cavity, and is used to transmit power; the output shaft is at least partially (or entirely) accommodated in the housing, and is used to match the working accessories (such as the bit); and the battery pack 100 is used to provide energy and auxiliary functions.

[0040] Figure 3 In the figure, the scale projected by the projection device 21 is projected onto the working surface of the power tool 200. The scale can be selectively overlapped with the position where the working accessory (the drill bit in the figure) abuts against the working surface to provide a scale function for the working accessory.

[0041] Since the battery pack 100 with auxiliary functions can provide auxiliary functions, the electric tool connected with the battery pack 100 with auxiliary functions can get rid of some auxiliary tools, and thus has higher practicality.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0043] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
