Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of general electric tools, in particular to a charger for electric tools and a combined system thereof. Background Art
[0002] In the prior art, as a whole machine tool manufacturer, after assembling the whole machine, once a defect is found, or the charger needs to be upgraded, the charger must be disassembled, resulting in cumbersome procedures and increased costs. Therefore, it is necessary to provide a charger that is easy to upgrade the program and reduces the procedures. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a charger for an electric tool and a combined system thereof to facilitate program upgrades.
[0004] The present application provides a charger for an electric tool, including a controller fixedly installed in a cavity formed by an upper shell and a lower shell cooperating with each other, the upper shell having two charging ports, and a burning port being provided on the controller, the burning port being located on the lower side of the controller; a burning slot being provided on the lower shell, the burning slot being a through hole, the burning card passing through the burning slot and connected to the burning port, and the upper shell and the lower shell being fixed by screws.
[0005] Furthermore, a glue filling area is provided on the upper surface of the controller.
[0006] Furthermore, the lower housing is provided with a groove, which extends along the length direction of the lower housing, wherein the burning notch portion is located in the groove.
[0007] Furthermore, the burning notches are located on the side walls and the bottom wall of the groove.
[0008] Furthermore, a label is attached to the outside of the burning slot.
[0009] Furthermore, the upper housing has two charging ports.
[0010] Furthermore, the charging voltage of each charging port is 20V.
[0011] An electric tool combination system comprises an electric tool and the above-mentioned charger. The electric tool has a battery pack and the charger charges the battery pack.
[0012] Furthermore, the electric tool is a brushless electric wrench.
[0013] The utility model reserves a burning slot at the bottom of the charger, so that the operator can debug the function of the charger without disassembling the charger, thereby avoiding unnecessary damage. When disassembly is not required, a small label is pasted on the burning slot, which does not affect the appearance of the product, saves disassembly costs, reduces processes, and brings convenience to after-sales firmware upgrades.

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0019] A charger for an electric tool includes a controller fixedly installed in a cavity formed by an upper housing 10 and a lower housing 20, wherein a burning port is provided on the controller and the burning port is located at the lower side of the controller; a burning slot 21 is provided on the lower housing 20 and the burning slot 21 is a through hole, and the upper housing 10 and the lower housing 20 are fixed by screws.
[0020] The control program is arranged inside the burning card 32 , and the burning card 32 passes through the burning slot 21 and is connected to the burning port.
[0021] A glue filling area is arranged on the upper surface of the controller.
[0022] The lower housing 20 is provided with a groove 22 , which extends along the length direction of the lower housing 20 , wherein the burning notch 21 is partially located in the groove 22 .
[0023] In order not to affect the observation of the battery pack status during debugging, the burning notch 21 is located on the side wall 23 and the bottom wall 24 of the groove 22, so that when the burning card 32 is inserted into the charger, the lower housing 20 can also be kept horizontal and can be placed horizontally on the table.
[0024] When debugging is not needed, a label is attached to the outside of the burning slot 21 to prevent dust from entering the charger.
[0025] The upper housing 10 has two charging ports 11. The charging voltage of each charging port 11 is 20V.
[0026] An electric tool combination system comprises an electric tool and the above-mentioned charger. The electric tool has a battery pack and the charger charges the battery pack.
[0027] Furthermore, the electric tool is a brushless electric wrench.
[0028] The principle of the utility model is: a burning notch 21 is reserved at the bottom of the charger, so that the operator can directly adjust the functional parameters of the charger without disassembling the charger.
[0029] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
