[0001] This application relates to the field of electric nail gun technology, and more particularly to a driving device for an electric nail gun and an electric nail gun. Background Technology

[0002] The drive mechanism of an electric nail gun mainly includes a motor, a linkage mechanism, and a push rod. The motor's output is connected to the linkage mechanism, and the push rod is also connected to the linkage mechanism. The motor drives the linkage mechanism to move, which in turn moves the push rod back and forth in a set direction to clamp the nail. However, due to the structural design of the linkage mechanism, it suffers from significant wear, affecting its transmission accuracy. Utility Model Content

[0003] This application provides a driving device for an electric nail gun and an electric nail gun to solve the problems existing in the related technology. The technical solution is as follows:

[0009] The second link has a first end rotatably connected to the first link and a second end rotatably connected to the push rod. The second end of the second link can reciprocate along the direction of movement of the push rod as the first link rotates.

[0010] In one embodiment, the substrate has a guide groove that extends along the movement direction of the push rod;

[0011] The driving mechanism of the electric nail gun also includes:

[0012] A limiting member is provided on the push rod, and the limiting member is rotatably connected to the second end of the second connecting rod. A portion of the limiting member is located in the guide groove and is slidably engaged with the guide groove.

[0013] In one embodiment, the limiting member is provided with a limiting portion that extends along at least one side of the moving direction of the push rod, and the limiting portion is located in the guide groove and slidably engaged with the guide groove.

[0014] In one embodiment, the limiting member is provided with a trigger portion;

[0015] The base is equipped with a first sensor and a second sensor. When the push rod moves outward relative to the base to a set position, the contact of the first sensor cooperates with the triggering part to trigger the first sensor, thereby stopping the power supply. When the push rod moves inward relative to the base to a set position, the contact of the second sensor cooperates with the triggering part to trigger the second sensor, thereby stopping the power supply.

[0016] In one embodiment, the push rod is provided with a positioning groove;

[0017] The limiting member further includes a connecting portion, which is adapted to the positioning groove and connected to the push rod. In one embodiment, the base includes:

[0018] The main body supports the motor and the push rod;

[0019] A first connecting plate, which is separately disposed from the main body, is located on the main body; and

[0020] The second connecting plate is separately disposed from the first connecting plate, and the second connecting plate and the first connecting plate together form the guide groove.

[0021] In one embodiment, the first connecting plate has a top plate portion and a side plate portion. The top plate portion is connected to the main body and has a positioning hole that extends through the top plate portion both vertically and horizontally. The side plate portion is located on one side of the top plate portion perpendicular to the moving direction of the push rod. Both the top plate portion and the side plate portion have a first connecting hole.

[0022] The second connecting plate and the side plate form the guide groove. The second connecting plate is provided with a positioning protrusion that is adapted to the positioning hole. The positioning protrusion has a second connecting hole, which is connected to the first connecting hole by a fastener to fix the second connecting plate and the first connecting plate together.

[0023] In one embodiment, the driving device of the electric nail gun further includes:

[0024] An elastic element, one end of which abuts against the base and the other end of which abuts against the push rod, is used to provide a driving force for the push rod to move inward relative to the base.

[0025] In one embodiment, the elastic element is sleeved on the outer peripheral wall of the push rod.

[0026] In one embodiment, the first link has a mounting hole;

[0027] The driving mechanism of the electric nail gun also includes:

[0028] A coupling is disposed in the mounting hole, the coupling having a coupling hole that is adapted to the output end of the motor to connect the first connecting rod and the output end of the motor together.

[0029] Secondly, embodiments of this application provide an electric nail gun, including the aforementioned driving device for the electric nail gun.

[0030] The advantages or beneficial effects of the above technical solutions include at least the following:

[0031] The driving device of this electric nail gun includes a base, a motor, a push rod, a first connecting rod, and a second connecting rod. The motor drives the first connecting rod to rotate, which in turn causes the second connecting rod to swing. This allows the second end of the second connecting rod to reciprocate along the direction of the push rod, thereby moving the push rod in a set direction to quickly clamp nails. Since the rotation of the motor's output end is converted into linear motion through the linkage of the first and second connecting rods, the linear motion process is relatively stable and does not cause a decrease in accuracy due to wear of the first and second connecting rods.

[0032] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

Detailed Implementation

[0050] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0051] See Figures 1-14 This invention illustrates a preferred embodiment of a driving device for an electric nail gun, comprising:

[0052] Matrix 1;

[0053] Motor 2, motor 2 is mounted on base 1;

[0054] Push rod 3 is movably mounted on base 1;

[0055] The first link 4 is connected to the output end of the motor 2, and the first link 4 can rotate with the output end of the motor 2; and

[0056] The second link 5 has its first end rotatably connected to the first link 4 and its second end rotatably connected to the push rod 3. The second end of the second link 5 can reciprocate along the direction of movement of the push rod 3 as the first link 4 rotates.

[0057] The driving device of this electric nail gun includes a base 1, a motor 2, a push rod 3, a first connecting rod 4, and a second connecting rod 5. The motor 2 drives the first connecting rod 4 to rotate, and the rotation of the first connecting rod 4 causes the second connecting rod 5 to swing, so that the second end of the second connecting rod 5 can reciprocate along the moving direction of the push rod 3, thereby driving the push rod 3 to move in a set direction to achieve rapid nail clamping. Since the rotation of the output end of the motor 2 is converted into linear motion through the linkage of the first connecting rod 4 and the second connecting rod 5, the linear motion process is relatively stable and there is no problem of decreased accuracy due to wear of the first connecting rod 4 and the second connecting rod 5.

[0058] Specifically, motor 2 can be either a brushed motor or a brushless motor.

[0059] See Figure 3-Figure 8 In one embodiment, the base 1 has a guide groove 14 that extends along the moving direction of the push rod 3.

[0060] The drive mechanism for an electric nail gun also includes:

[0061] A limiting component 6 is mounted on the push rod 3 and is rotatably connected to the second end of the second connecting rod 5. A portion of the limiting component 6 is located within the guide groove 14 and is slidably engaged with it. That is, the push rod 3 is rotatably connected to the second end of the second connecting rod 5 via the limiting component 6. During the movement of the limiting component 6 driven by the second connecting rod 5, in addition to the force acting in the direction of the push rod 3's movement, there are also forces acting in the up, down, left, and right directions, which could cause the push rod 3 to rotate or swing during use. The engagement of the limiting component 6 with the guide groove 14 of the base 1 effectively limits the movement of the limiting component 6, ensuring that the push rod 3 does not swing or rotate, thus improving the stability and service life of the electric nail gun.

[0062] See Figure 8 In one embodiment, the limiting member 6 is provided with a limiting part 61, which extends along at least one side of the moving direction of the push rod 3. The limiting part 61 is located in the guide groove 14 and is slidably engaged with the guide groove 14. That is, the limiting part 6 is moved and limited by the engagement of the limiting part 61 with the guide groove 14, thereby limiting the movement of the push rod 3 and making the push rod 3 move more smoothly and stably.

[0063] In one embodiment, the limiting member 6 is provided with a trigger part 62;

[0064] The base 1 is equipped with a first sensor 7 and a second sensor 8, which are spaced apart along the moving direction of the push rod 3. When the push rod 3 moves outward relative to the base 1 to a set position, the contact of the first sensor 7 cooperates with the trigger part 62 to trigger the first sensor 7, thereby stopping the motor 2 and limiting the position of the push rod 3 relative to the base 1. When the push rod 3 moves inward relative to the base 1 to a set position, the contact of the second sensor 8 cooperates with the trigger part 62 to trigger the second sensor 8, thereby stopping the motor 2 and limiting the position of the push rod 3 relative to the base 1. This achieves the limitation of the movement stroke of the push rod 3. When the push rod 3 moves to the set position, the trigger part 62 cooperates with the contact of the corresponding sensor to trigger the corresponding sensor, thereby causing the controller of the electric nail gun to control the motor 2 to automatically stop according to the feedback information of the sensor, thereby achieving accurate positioning of the push rod 3.

[0065] Both the first sensor 7 and the second sensor 8 can be contact sensors or non-contact sensors.

[0066] Of course, in other implementations, the electric nail gun may be equipped with only one sensor. In this case, the motor can be shut down by calculating the distance or time away from the sensor.

[0067] See Figure 8 and Figure 11 In one embodiment, the push rod 3 is provided with a positioning groove 31;

[0068] The limiting member 6 is also provided with a connecting part 63, which is adapted to the positioning groove 31 and is connected to the push rod 3. In this way, when installing the limiting member 6, the limiting member 6 is positioned by using the cooperation between the connecting part 63 and the positioning groove 31, and finally the connecting part 63 is fixed together with the push rod 3, which makes it easy to quickly and correctly install the limiting member 6 onto the push rod 3.

[0069] See Figure 8 In one embodiment, the limiting part 61 is located above the trigger part 62, the connecting part 63 extends along the moving direction of the limiting member 6, and the connecting part 63, the limiting part 61, and the trigger part 62 are arranged in a cross shape, so that the limiting member 6 is formed into a cross-shaped structure.

[0070] See Figure 2 To simplify the machining of the guide groove 14, in one embodiment, the substrate 1 includes:

[0071] Main body 11, which supports motor 2 and push rod 3;

[0072] A first connecting plate 12 is separately disposed from the main body 11, and the first connecting plate 12 is disposed on the main body 11; and

[0073] The second connecting plate 13 is separately set from the first connecting plate 12, and the second connecting plate 13 and the first connecting plate 12 form a guide groove 14.

[0074] See Figure 9 and Figure 10 In one embodiment, the first connecting plate 12 is provided with a top plate portion 121 and a side plate portion 122. The top plate portion 121 is connected to the main body 11. The top plate portion 121 has a positioning hole 1211, which passes through the top plate portion 121 both vertically. The side plate portion 122 is provided on one side of the top plate portion 121 along the moving direction perpendicular to the push rod 3. Both the top plate portion 121 and the side plate portion 122 have a first connecting hole.

[0075] The second connecting plate 13 and the side plate portion 122 form a guide groove 14. The second connecting plate 13 is provided with a positioning protrusion 131, which is adapted to a positioning hole 1211. The positioning protrusion 131 has a second connecting hole, which is connected to the first connecting hole by a fastener to fix the second connecting plate 13 and the first connecting plate 12 together. In this way, the positioning protrusion 131 and the positioning hole 1211 can be used to install and position the second connecting plate 13, which facilitates the quick and correct installation of the second connecting plate 13 onto the first connecting plate 12, greatly improving installation efficiency. At the same time, the fasteners can be used to connect the first connecting hole and the second connecting hole to reliably fix the first connecting plate 12 and the second connecting plate 13 together, resulting in high connection stability.

[0076] See Figure 3 In one embodiment, the driving device of the electric nail gun further includes:

[0077] The elastic element 9 has one end abutting against the base 1 and the other end abutting against the push rod 3. The elastic element 9 provides a driving force for the push rod 3 to move inward relative to the base 1. See also... Figure 4 When the push rod 3 is driven by the linkage of the first link 4 and the second link 5 to move inward relative to the base 1 to the set position, the included angle between the first link 4 and the second link 5 is the smallest. The linkage of the first link 4 and the second link 5 generates a greater lateral force than axial force on the push rod 3. Since the elastic element 9 can provide the push rod 3 with the driving force to move inward relative to the base 1, it increases the axial force when the push rod 3 moves inward. In cooperation with the guide groove 14, the push rod 3 moves inward more smoothly.

[0078] See Figure 3 In one embodiment, the elastic element 9 is sleeved on the outer peripheral wall of the push rod 3, and the push rod 3 guides the elastic element 9 so that the elastic element 9 can extend and retract more smoothly.

[0079] In one embodiment, the elastic element 9 can be a spring, or an elastic structure such as a sheet, elastic rubber element, or bellows, as long as it can provide the push rod 3 with a driving force to move inward relative to the base 1.

[0080] In one embodiment, the base 1 has a guide hole, through which the push rod 3 is movably inserted to guide its movement, making the push rod 3 move more smoothly and stably.

[0081] See Figures 13-14 In one embodiment, the first link 4 has a mounting hole 41;

[0082] The drive mechanism for an electric nail gun also includes:

[0083] A coupling 60 is provided in the mounting hole 41 and has a coupling hole 601. The coupling hole 601 is adapted to the output end of the motor 2 to connect the first connecting rod 4 and the output end of the motor 2 together. That is, the output end of the motor 2 and the first connecting rod 4 are connected together through the coupling 60. The coupling 60 can also separate the output end of the motor 2 and the first connecting rod 4, which facilitates disassembly and assembly of the output end of the motor 2 and the first connecting rod 4 during later maintenance, thereby reducing the difficulty of maintenance.

[0084] See Figure 14 In one embodiment, the first connecting rod 4 is further provided with a positioning part 42, which is disposed on the wall of the mounting hole 41.

[0085] The outer peripheral wall of the coupling 60 has a positioning groove 602, which is adapted to the positioning part 42. That is, the positioning part 42 is inserted into the positioning groove 602 to position the coupling 60, restrict the coupling 60 from rotating relative to the first connecting rod 4, and ensure that the output end of the motor 2 can efficiently transmit torque to the first connecting rod 4.

[0086] In one embodiment, there are two positioning parts 42 and two positioning slots 602. The two positioning parts 42 are respectively inserted into a corresponding positioning slot 602 to reliably limit the rotation of the coupling 60 relative to the first connecting rod 4.

[0087] In one embodiment, the driving device of the electric nail gun further includes:

[0088] Bearing sleeve 90, the bearing sleeve 90 is disposed between motor 2 and first connecting rod 4; and

[0089] Bearing 80 is located inside bearing sleeve 90;

[0090] The output end of motor 2 is provided with the center hole of bearing 80 and bearing sleeve 90, and the inner ring of bearing 80 can rotate with the output end of motor 2. In this way, bearing 80 can be used to support and limit the output end of motor 2, thereby reducing the sway of the output end of motor 2.

[0091] See Figure 14 In one embodiment, for ease of installation, the output end of the motor 2 is provided with an output shaft 50, which passes through the center hole of the bearing 80 and the bearing sleeve 90, and is inserted into the coupling hole 601.

[0092] See Figure 14 For ease of installation, the drive mechanism of the electric nail gun also includes:

[0093] The locking fastener 70 is located at the end of the output shaft 50 away from the motor 2, and the locking fastener 70 can abut against the end of the coupling 60 away from the motor 2 to prevent the output shaft 50 from disengaging from the coupling 60.

[0094] See Figure 2 In one embodiment, the driving device of the electric nail gun further includes:

[0095] The anti-wear sleeve 10 is provided on the base 1. The anti-wear sleeve 10 has the above-mentioned guide hole. By providing the guide hole on the anti-wear sleeve 10, wear can be reduced, thereby effectively avoiding the problem of decreased accuracy caused by the movement and wear of the push rod 3, and enabling the push rod 3 to move more steadily and for longer.

[0096] In one embodiment, there are two anti-wear sleeves 10, which are spaced apart along the moving direction of the push rod 3.

[0097] In one embodiment, the anti-wear sleeve 10 is made of copper to give it better anti-wear performance, which can greatly improve its service life and reduce maintenance costs.

[0098] Of course, in other embodiments, the anti-wear sleeve 10 may also be a structure made of other materials with wear-resistant properties, such as stainless steel.

[0099] See Figure 2 In one embodiment, the driving device of the electric nail gun further includes:

[0100] A reducer 20 is mounted on the base 1. The input end of the reducer 20 is connected to the output end of the motor 2, and the input end of the reducer 20 can rotate with the output end of the motor 2. The output end of the reducer 20 is connected to the first end of the first connecting rod 4 to efficiently transmit the torque from the output end of the motor 2 to the first connecting rod 4. The reducer 20 and the motor 2 are arranged side-by-side in a horizontal direction. Because the motor 2 and the reducer 20 are arranged side-by-side in a horizontal direction, the space utilization rate of the drive device in the horizontal direction is improved, preventing the drive device from occupying too much space in one direction. This also prevents the electric nail gun from occupying too much space in one direction, making it more convenient for the user to hold the electric nail gun.

[0101] It can be understood that the parallel arrangement of the reducer 20 and the motor 2 in the horizontal direction means that the output shaft of the reducer 20 and the output shaft of the motor 2 are arranged in the horizontal direction.

[0102] In one embodiment, the driving device of the electric nail gun further includes:

[0103] The transmission mechanism 30 has its input end connected to the output end of the motor 2, and its output end can rotate with the input end of the transmission mechanism 30. The output end of the transmission mechanism 30 is connected to the input end of the reducer 20 so that the torque of the motor 2 can be transmitted to the input end of the reducer 20 through the transmission mechanism 30.

[0104] See Figure 12 In one embodiment, the transmission mechanism 30 includes:

[0105] The drive gear 301 is sleeved on the output end of the motor 2 and can rotate with the output end of the motor 2.

[0106] Driven gear 302 and driving gear 301 are arranged side by side in the horizontal direction. Driven gear 302 meshes with driving gear 301 and is connected to the input end of reducer 20. That is, transmission mechanism 30 is a gear mechanism. Gear mechanism has the advantages of maintaining accurate transmission ratio, large speed range, high transmission efficiency, long service life, compact structure, small size and reliable operation. It can improve the transmission efficiency of power device while reducing the space occupied, so that the overall structure of power device is more compact and occupies less space.

[0107] See Figure 12 In one embodiment, the transmission mechanism 30 further includes:

[0108] An intermediate gear 303 is rotatably mounted on the motor mounting housing 40. The intermediate gear 303 is located between the driving gear 301 and the driven gear 302, with the driving gear 301 meshing with the driven gear 302 via the intermediate gear 303. Because the driving gear 301 meshes with the driven gear 302 via the intermediate gear 303, the power of the driving gear 301 can be transmitted to the driven gear 302. Simultaneously, since the intermediate gear 303 is rotatably mounted on the base 1, it can support both the driving gear 301 and the driven gear 302, improving the assembly stability of the driving gear 301 and the driven gear 302, thereby further improving the transmission efficiency of the transmission mechanism 30.

[0109] Of course, in other embodiments, the transmission mechanism 30 may also adopt a chain drive mechanism 30, belt drive mechanism 30 or other transmission structures.

[0110] In one embodiment, the motor mounting housing 40 has a receiving cavity, in which the transmission mechanism 30 is disposed to accommodate the transmission mechanism 30. This not only improves the utilization rate of the internal space of the motor mounting housing 40, but also protects the transmission mechanism 30.

[0111] A preferred embodiment of this utility model provides an electric nail gun, including the aforementioned driving device for the electric nail gun.

[0112] The electric nail gun of this invention, due to the adoption of the aforementioned driving device, also converts the rotation of the output end of the motor 2 into linear motion through the linkage of the first link 4 and the second link 5. This linear motion process is relatively stable and will not cause a decrease in accuracy due to wear of the first link 4 and the second link 5.
