For a better understanding of the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.
The examples shown in connection with fig. 1 to 3 relate to a Battery Pack (Battery Pack), and more particularly, to a Battery Pack for use in a fascia gun, which is configured in a cylindrical shape, is detachably or non-detachably mounted below a main body of a body of the fascia gun, and is used as a handle of the fascia gun while supplying power to a motor in the main body of the body.
Alternatively, the outer case of the battery pack 10 may be cylindrical or column-shaped. The shell is provided with at least one battery unit (not shown) and a circuit board 30 connected with the battery unit, and the circuit board is provided with a control IC circuit for controlling the charging and discharging of the battery pack and the function detection management of the battery pack, such as electric quantity monitoring, charging and discharging parameter detection, battery temperature detection and the like.
In conjunction with the illustration, the battery pack further includes a light guide unit 20 disposed on the battery pack case and corresponding to the circuit board. The light guide unit 20 includes a base 20A attached to or embedded in a sidewall of a case of the battery pack and a hollow light guide pillar 20B behind the base. The base body of the light guide unit and the light guide column are made of soft rubber materials.
The Battery unit is a single Battery, especially a rechargeable Battery unit, such as a lithium Battery, a nickel metal hydride Battery, etc., and a Battery pack may have a plurality of Battery units electrically connected together in a suitable manner, such as series connection, parallel connection or a combination thereof, to form one or more Battery packs (Battery modules).
The battery pack typically has communication ports, such as positive and negative terminals and S and T terminals, coupled to corresponding electrodes and ports on the body (i.e., the main unit) for providing power and data communication for proper operation of the motor assembly within the body.
In order to know the state of the electric quantity allowance of the battery pack, a detection module for detecting the voltage state of the battery pack is arranged on the circuit board, the current electric quantity of the battery is known by measuring the voltage of the battery pack, and the current electric quantity of the battery is displayed on a shell of the battery pack. For example, in the illustration, the outer surface of the substrate 20A is divided into a first region and a second region, the first region is a predetermined position on the substrate surface, and the predetermined position is set to have a predetermined pattern, such as the power monitoring key pattern 21, the power remaining amount display pattern 22, the charging pattern 23, etc., exemplarily shown in fig. 1, with the region of the substrate surface other than the first region being the second region, and the second region being all black.
Referring to fig. 1, 2 and 3, the circuit board 30 includes a PCB board body 31, and circuits and electric devices disposed on the PCB board body, including a control IC circuit 32, a port 33, a plurality of LED light-emitting elements 34, a charging interface 35 and an electric quantity monitoring key switch 36. Referring to fig. 1 and 3, the plurality of LED light emitting elements 34, which are used as indicator lights, can be powered by the at least one battery unit to be driven and lighted, and are displayed through the pattern of the first region of the surface into which the light guide bar 20B is introduced. Optionally, the light guide bars 20B correspond to the LED light emitting elements 34 one to one, and the number of the light guide bars is the same.
In combination with the illustration, the electric quantity monitoring key pattern 21 corresponds to the electric quantity monitoring key switch 36 on the circuit board 30, and the electric quantity monitoring key switch 36 can be triggered by pressing the position corresponding to the electric quantity monitoring key pattern 21 on the surface of the battery pack, so as to detect the charge state of the battery pack, obtain the remaining battery capacity, and control the LED light-emitting element 34 corresponding to the electric quantity, so as to display on the surface of the substrate 20.
Alternatively, the arrangement of the LED light emitting elements on the circuit board may be a linear arrangement, a dot matrix arrangement, or the like.
In order to enable a user to visually acquire the battery state on the shell of the battery pack, the material of the base body arranged on the shell of the battery pack can be directly a semitransparent rubber material, or the semitransparent rubber material can be arranged as a filling layer in the base body, and the thickness of the semitransparent rubber material is 0.1-0.5 mm.

Each of the light guide bars 20B has a hollow cylindrical structure, such as a cylinder, a prism, etc. The hollow part corresponds to the position of the LED indicator lamp on the built-in circuit board. The light transmission efficiency in the hollow part of the light guide unit is much higher than that in the light guide material due to the phenomena of refraction, diffuse reflection and the like of light in the rubber material. The structure effectively prevents the interference phenomenon between adjacent LED light sources, so that the resolution of the matrix for the number of the LED lamps is higher.
In an exemplary embodiment, the LED light emitting elements are linearly arranged on the circuit board, and therefore, the light guide units are also linearly arranged, and the light guide units and the LED light emitting elements are in a one-to-one correspondence relationship. Therefore, when one or more LED light-emitting elements are lighted, the corresponding light guide units can efficiently transmit light to the lower surface of the rubber base body. Then, on the upper surface of the rubber base body, the corresponding preset patterns are luminous and bright, and the purpose of indicating the battery state on the battery pack shell can be achieved.
In another embodiment, an LED light emitting element is used to indicate the progress of charging the battery pack.
In an optional embodiment, when the battery pack is in a charging state, the current electric quantity of the battery pack can be obtained by detecting the voltage of the battery pack through a detection module on the circuit board. According to the current electric quantity of the battery pack, the LED light-emitting element on the circuit board is lightened in a running horse lamp mode. In an optional mode, when the LED light emitting element on the circuit board works, the corresponding dot pattern on the rubber base changes the brightness thereof, and is not affected by the interference of the flickering light, so as to achieve the effect of displaying the charging process on the battery pack case.
In yet another embodiment, an LED light element may be used to indicate the current operating temperature, sleep state, etc. of the battery pack.
