[0066] In this utility model, "front" and "rear" refer to... Figure 1 The markings in the text shall prevail.

[0067] The following is based on Figures 1 to 15 The power device of this utility model is described in detail.

[0068] In this embodiment, such as Figure 1 , Figures 6 to 10 As shown, the power tool 100 includes an adjustment button 1, a mounting channel 21, a housing 3, a control board 5, and a main switch 6. The housing 3 forms the outer contour structure of the power tool 100. The control board 5 is provided with switch contacts 51, and the main switch 6 is used to control the start and stop of the power tool 100. The power tool 100 includes, but is not limited to, an electric drill, an electric screwdriver, an electric wrench, and a jigsaw.

[0069] Specifically, the power tool 100 includes an output shaft 7, a motor 91, and a transmission assembly 92. The output end of the output shaft 7 is used to assemble with a tool head (such as a drill bit or screwdriver). The motor 91 drives the output shaft 7 to rotate through the transmission assembly 92, thereby enabling the output shaft 7 to directly or indirectly drive the tool head to operate. The main switch 6 is used to control the start and stop of the motor 91, thereby controlling the start and stop of the power tool 100. Furthermore, the power tool 100 can be a DC power tool, equipped with a battery pack 8 to power it. Alternatively, the power tool 100 can be an AC power-powered tool, equipped with a power cord for connection to AC power. It should be understood that the specific structure of the transmission assembly 92 and the working principle between the transmission assembly 92 and the motor 91 can be found in any existing related power tool, and will not be elaborated further here.

[0070] like Figures 6 to 10 As shown, the adjustment button 1 includes a pressing part 11, a main body 12, a trigger part 13, and a connecting arm 14. The pressing part 11 is connected to the main body 12 through the connecting arm 14. The trigger part 13 is connected to at least one of the pressing part 11 and the connecting arm 14. The main body 12 is installed in the mounting channel 21 and the two are interference-fitted. The main body 12 is installed on the housing 3 through the mounting channel 21. The interference fit between the main body 12 and the mounting channel 21 can be that the peripheral outer wall of the main body 12 is partially interference-fitted with the mounting channel 21, or the entire peripheral outer wall of the main body 12 is interference-fitted with the mounting channel 21. When it is necessary to change the working state of the power tool 100 other than the start and stop of the power tool 100, the user can manually press the pressing part 11 of the adjustment button 1. The pressing part 11 will be displaced or deformed in the direction of the external force when pressed by the external force. During this process, since the main body 12 is interference-fitted with the mounting channel 21, the main body 12 will not move in the direction of the external force. In this way, the pressing part 11 can force the connecting arm 14 to undergo elastic deformation. Because the connecting arm 14 undergoes elastic deformation, the trigger part 13 can be displaced to press the switch contact 51, thereby changing the working state of the power tool 100 other than the start and stop.

[0071] In the prior art, the connection between the pressing part and the main body of the adjustment button does not have a hollow structure. In the later stage of pressing, the adjustment button will be squeezed and deformed, and the squeezing force will increase. The interference fit between the main body and the mounting channel is not enough to resist the deformation force of the adjustment button, which will cause the adjustment button to slip in the mounting channel. Ultimately, the adjustment button will keep pressing the switch contact, causing the power tool to malfunction.

[0072] In the above-mentioned solution of this application, the adjustment button 1 is improved. The pressing part 11 and the main body 12 are connected by a connecting arm 14. The reciprocating motion of the pressing part 11 is achieved by the elastic deformation of the connecting arm 14. The deformation of the connecting arm 14 is a swing deformation. The force required for the unit deformation of the connecting arm 14 is small and stable, and the pressing is easy. The interference between the main body and the mounting channel is sufficient to resist the deformation force of the connecting arm 14, so that the adjustment button is not easy to slip relative to the mounting channel, thus avoiding the adjustment button from constantly pressing the switch contact and avoiding abnormalities in the power tool.

[0073] In one implementation, such as Figure 1 As shown, the main switch 6 is a trigger switch, which allows the user to control the start and stop of the power tool 100 by manually pressing or pulling the trigger.

[0074] In one embodiment, the adjustment button 1 functions as at least one of gear adjustment, mode switching, sub-unit adjustment, and brightness adjustment to change the working state of the power tool 100 other than start / stop. Specifically, when adjusting the gear using the adjustment button 1, the speed, torque, and power of the power tool 100 can be adjusted. When switching modes using the adjustment button 1, the working mode of the power tool 100 can be switched, such as forward rotation automatic stop mode, reverse rotation automatic stop mode, special working condition adjustment mode, rotation mode, impact mode, etc. When adjusting the sub-unit using the adjustment button 1, the switch mode, Bluetooth on / off status, etc., can be adjusted.

[0075] In this solution, the adjustment button 1 can be located anywhere on the housing 3. For example, taking the power tool 100 as an electric drill as an example, ... Figure 1 As shown, the adjustment button 1 can be located on the upper part of the base housing 31 of the casing 3, such as... Figure 2 As shown, the adjustment button 1 can also be located at the rear of the base housing 31 of the casing 3, such as... Figure 3 As shown, the adjustment button 1 can also be located at the rear of the motor housing 32 of the housing 3, such as... Figure 4 As shown, the adjustment button 1 can also be located at the front of the housing 3, between the main switch 6 and the output shaft 7. Furthermore, as... Figure 5 As shown, when the power tool 100 is a jigsaw, the adjustment button 1 can be located at the rear of the housing 3 and below the handle housing 33.

[0076] The following description takes the power tool 100 as an electric drill and the adjustment button 1 as an example of the base housing 31 of the machine housing 3.

[0077] In one implementation, such as Figures 7 to 9As shown, there are at least two connecting arms 14, and a hollow portion 15 is formed between at least two adjacent connecting arms 14. In this solution, by setting multiple connecting arms 14, the stability of the connection between the pressing part 11 and the main body 12 can be improved while reducing the force required for the connecting arms 14 to deform. This is beneficial for the pressing part 11 to displace or deform along the direction of the external force.

[0078] Furthermore, such as Figure 9 As shown, all the connecting arms 14 are evenly spaced along the circumference of the pressing part 11, and a hollow part 15 is formed between two adjacent connecting arms 14. In this design, all the connecting arms 14 are evenly distributed, which is beneficial to the even distribution of force on the connecting arms 14 and improves the stability of the adjustment button 1.

[0079] Furthermore, such as Figures 7 to 9 As shown, the cross-sectional diameter of the pressing part 11 is smaller than the cross-sectional diameter of the main body 12. The length of the connecting arm 14 extends radially along the pressing part 11, and the first end face 141 of the connecting arm 14 away from the pressing part 11 is connected to the inner wall of the main body 12. The length of the connecting arm 14 is L1, and the wall thickness of the main body 12 is t1, where 1:1 < L1:t1 ≤ 3:1. This solution, by limiting the dimensional relationship between the length of the connecting arm 14 and the wall thickness of the main body 12, makes the force required for a unit deformation of the connecting arm 14 smaller, and the interference fit between the main body and the mounting channel can resist the deformation force of the connecting arm 14.

[0080] In one implementation, such as Figure 8 and Figure 9 As shown, the number of hollowed-out portions 15 is n, the circumference of the first end face 141 of the connecting arm 14 away from the pressing portion 11 is C1, and the arc length of the first end face 141 is L2; ​​where L2:C1 is This solution limits the dimensional relationship between the connecting arm 14 and the hollow part 15 so that the elastic deformation force of the connecting arm 14 is within the required range, thereby ensuring that the pressing operation of the adjustment button 1 is easy and effortless, and that the adjustment button 1 can quickly return to its initial state after the pressing force is removed.

[0081] In one implementation, such as Figure 8 As shown, the main body 12 has multiple extension arms 121 on its end face facing the connecting arm 14. Each extension arm 121 is connected to the connecting arm 14 in a one-to-one correspondence, increasing the size of the hollow portion 15. Thus, when the pressing part 11 is pressed by external force, the extension arms 121 can elastically deform along with the connecting arm 14, further reducing the pressing force required for the adjustment button 1 to deform per unit, and accelerating the speed at which the trigger part 13 presses the switch contact 51, thereby quickly changing the working state of the power tool 100 other than start / stop. Furthermore, the connected extension arms 121 and the connecting arm 14 form an L-shaped structure.

[0082] In one implementation, such as Figure 8 As shown, adjustment button 1 is a one-piece molded structure, which is easy to process.

[0083] In one implementation, such as Figure 7 and Figure 9 As shown, both the pressing part 11 and the triggering part 13 are cylindrical and coaxial. The triggering part 13 is connected to the end of the pressing part 11 away from the main body part 12. The main body part 12 is arranged around the triggering part 13. The end of the connecting arm 14 away from the main body part 12 is connected to the pressing part 11 and the triggering part 13 respectively. In this way, when the connecting arm 14 undergoes elastic deformation, the connecting arm 14 can instantly drive the triggering part 13 to move to press the switch contact 51, thereby accelerating the triggering speed.

[0084] In one implementation, such as Figure 7 , Figure 8 and Figure 10 As shown, the power tool 100 also includes a mounting panel 2, which forms a mounting channel 21. The mounting panel 2 is mounted on the housing 3, and the adjustment button 1 is mounted on the housing 3 through the mounting panel 2. Since the housing 3 is larger in size, the processing complexity is higher than that of the mounting panel 2. Compared with the solution of directly mounting the adjustment button 1 on the housing 3, this solution can reduce the modification of the housing 3, reduce the assembly compatibility between the housing 3 and the adjustment button 1, and is beneficial to cost control.

[0085] In one implementation, such as Figures 11 to 15 As shown, the power tool 100 includes a lighting assembly 4 and a battery pack 8. The lighting assembly 4 includes a lamp plate 41, a lampshade 42, and an adhesive element 43. The lamp plate 41 includes a plate body 411 and a lead wire 412 connected to the plate body 411. The lead wire 412 is used to electrically connect to the main control board of the power tool 100. The battery pack 8 supplies power to the lighting assembly 4 through the lead wire 412. When the main control board issues a lighting command, the lamp plate 41 emits light. The lamp plate 41 can be a light source plate or include a plate body and LEDs mounted on the plate body. The lampshade 42 has a groove 421, in which the lamp plate 41 is installed. The lead wire 412 is partially led out to the outside of the groove 421. The light emitted by the lamp plate 41 passes through the lampshade 42 and illuminates the target workspace of the power tool 100. The adhesive element 43 wraps around the connection between the lead wire 412 and the plate 411, and the adhesive element 43 can protect the connection between the lead wire 412 and the plate 411.

[0086] The groove 421 has a mounting wall 4212, and the adhesive element 43 is respectively bonded to the mounting wall 4212, the plate 411, and the lead wire 412, so that the lamp cover 42, the plate 411 and the lead wire 412 are connected as a whole. In this way, when the plate 411 and the lamp cover 42 vibrate with the power tool 100, the lead wire 412 can maintain the same frequency of vibration as the lamp plate 41 and the lamp cover 42 as much as possible, avoiding the lead wire 412 from swinging in the opposite direction relative to the lamp plate 41 and the lamp cover 42, which can reduce the probability of the lead wire 412 bending or reduce the bending amplitude of the lead wire 412. The end face of the mounting wall 4212 extends in a direction away from the bottom of the groove 421 to form an extension 42121. The extension 42121 is used for bonding the adhesive element 43 to extend the wrapping length of the adhesive element 43 along the axial direction of the lead wire 412. In addition, the extension 42121 can also increase the bonding area between the mounting wall 4212 and the adhesive element 43, thereby further reducing the probability of the lead wire 412 bending or reducing the bending range of the lead wire 412.

[0087] The above technical solution improves the lighting component 4 of the power tool 100 by configuring a mounting wall 4212 on the groove 421 of the lampshade 42, so that the lampshade 42, the plate 411 and the lead wire 412 are connected as a whole by the adhesive element 43. Furthermore, an extension 42121 is provided on the mounting wall 4212 to extend the wrapping length formed by the adhesive element 43 along the axial direction of the lead wire 412. While ensuring the miniaturization design of the lampshade 42, the bonding firmness of the lampshade 42, the plate 411 and the lead wire 412 is improved as much as possible, so as to ensure that the lead wire 412 can vibrate in the same frequency as the lampshade 42, the plate 411 and the whole machine, thereby reducing the probability of bending of the lead wire 412 or reducing the bending amplitude of the lead wire 412, and improving the service life of the lighting component 4.

[0088] It should be explained that the lighting component 4 in this application can also be applied to power tools powered by AC power, such power tools being connected to the mains power via a power cord to obtain electrical energy.

[0089] In one implementation, such as Figure 13 As shown, the extension 42121 extends along the lead-out direction of the lead wire 412. In this way, the extension length of the extension 42121 can be used as much as possible to meet the requirement of extending the wrapping length of the adhesive element 43 along the axial direction of the lead wire 412, thereby improving the utilization rate of the extension 42121. While effectively protecting the lead wire 412, it is also conducive to the miniaturization design of the lamp cover 42.

[0090] In one implementation, such as Figures 13 to 15As shown, the groove 421 has a mounting wall 4212, which is located close to the lead wire 412. That is, among the groove walls of the groove 421, the mounting wall 4212 is closest to the lead wire 412. The other groove walls of the groove 421 are not bonded to the adhesive element 43. That is, only one mounting wall 4212 of the groove 421 is bonded to the adhesive element 43. While meeting the requirement of extending the wrapping length of the adhesive element 43 along the axial direction of the lead wire 412, it can avoid the overall size of the lamp cover 42 from increasing due to the configuration of corresponding extensions on each groove wall of the groove 421, which is not conducive to the control of the size of the power tool 100.

[0091] In one implementation, such as Figure 15 As shown, the cross-section of the extension 42121 is trapezoidal, which facilitates demolding and improves the yield.

[0092] Furthermore, such as Figure 13 and Figure 15 As shown, the mounting wall 4212 is provided with a recess 42122, which is at least partially located on the extension 42121. The adhesive element 43 is at least partially embedded in the recess 42122 and bonded to improve the bonding strength between the adhesive element 43 and the mounting wall 4212, thereby facilitating the synchronous vibration of the lead wire 412 and the lamp cover 42.

[0093] Furthermore, such as Figure 12 and Figure 14 As shown, the plate 411 is vertically disposed in the groove 421, and the front surface wall of the adhesive element 43 is bonded to the rear surface wall of the plate 411. Specifically, during the user's use of the power tool 100, the target workspace is usually located in front of the power tool 100. In order to make full use of the light emitted by the lighting component 4, the lighting component 4 usually emits light forward. In this solution, by vertically disposing the plate 411 in the groove 421, it is beneficial for the plate 411 to emit as much light as possible toward the target workspace. The mounting wall 4212 is provided with two abutting protrusions 4211. The two abutting protrusions 4211 abut against one side of the plate 411 in the vertical direction to reduce the contact area between the mounting wall 4212 and the plate 411. This reduces the accuracy requirements of the contact surface between the mounting wall 4212 and the plate 411. Furthermore, the two abutting protrusions 4211 are bonded to the two side surfaces of the adhesive element 43 to further strengthen the bond between the adhesive element 43 and the mounting wall 4212, thereby facilitating the synchronous vibration of the lead wire 412 and the lampshade 42.

[0094] Furthermore, such as Figure 14 and Figure 15As shown, at least two opposing groove walls of the groove 421 are respectively provided with abutment protrusions 4211. The at least two abutment protrusions 4211 abut against both sides of the lamp plate 41, so that the lamp plate 41 is engaged in the groove 421. The groove 421 abuts against the lamp plate 41 through the abutment protrusions 4211, thereby reducing the contact area between the groove 421 and the plate 411, and reducing the accuracy requirements of the contact surface between the groove wall of the groove 421 and the plate 411. In one specific embodiment, the groove 421 has four groove walls, each of which is provided with two abutment protrusions 4211, so that the plate 411 can be easily and stably engaged in the groove 421.

[0095] In one implementation, such as Figure 13 As shown, one end of the lead wire 412 is welded to the plate 411 and the weld joint is surrounded by the adhesive element 43 to prevent the solder joint between the lead wire 412 and the plate 411 from breaking due to bending fatigue.

[0096] In one implementation, such as Figure 13 As shown, the first plane is defined as a plane perpendicular to the axis of the lead wire 412, and the ratio of the projected area of ​​the adhesive element 43 and the lead wire 412 on the first plane is greater than or equal to 3, so as to increase the bonding area between the adhesive element 43 and the plate 411.

[0097] In one embodiment, the adhesive element 43 is a resin material, including but not limited to epoxy resin and polyurethane resin, which has strong adhesion and stability.

[0098] In one implementation, such as Figure 1 and Figure 11 As shown, the lighting component 4 is installed on the front side of the housing 3 so as to directly illuminate the target workspace.

[0099] In one implementation, such as Figure 11 As shown, the lampshade 42 is mounted on the housing 3 to enable the installation of the lighting assembly 4.

[0100] In one embodiment, the lighting component 4 and the main switch 6 are mounted on the front side of the housing 3. The lighting component 4 is located between the output shaft 7 and the main switch 6. The lighting component 4 is positioned close to the output shaft 7, which helps to concentrate the light emitted by the lighting component 4 on the tool head.
