The input end of the reducer is connected to the output end of the motor, and the output end of the reducer is connected to the linkage mechanism. The push rod is also connected to the linkage mechanism. The motor drives the input end of the reducer to rotate, which in turn drives the output end of the reducer to rotate. The reducer then transmits torque to the linkage mechanism, which converts the torque output by the reducer into linear motion, thereby driving the push rod to move back and forth in a set direction to clamp the nail. However, because the motor and reducer are coaxially arranged, the power unit occupies a relatively large space in one direction, which can easily obstruct the operator's view during operation.

[0044] 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.

[0045] See Figures 1-10 This invention illustrates a preferred embodiment of a power unit for an electric nail gun, comprising:

[0046] Matrix 1;

[0047] Motor 2, motor 2 is mounted on base 1;

[0048] Transmission mechanism 3, the input end of transmission mechanism 3 is connected to the output end of motor 2, and the output end of transmission mechanism 3 can rotate with the input end of transmission mechanism 3; and

[0049] The reducer 4 is mounted on the base 1. The input end of the reducer 4 is connected to the output end of the transmission mechanism 3, and the input end of the reducer 4 can rotate with the output end of the transmission mechanism 3. The output end of the reducer 4 is used to connect with the linkage mechanism 8. The reducer 4 and the motor 2 are arranged side by side in the horizontal direction.

[0050] The electric nail gun of this utility model includes a base 1, a motor 2, a transmission mechanism 3, and a reducer 4. The input end of the transmission mechanism 3 can rotate with the output end of the motor 2 to transmit the output torque of the motor 2 to the input end of the transmission mechanism 3. The output end of the transmission mechanism 3 can rotate with the input end of the transmission mechanism 3 to transmit the torque output from the input end of the transmission mechanism 3 to the output end of the transmission mechanism 3. The input end of the reducer 4 can rotate with the output end of the transmission mechanism 3 to transmit the torque output by the motor 2 to the reducer 4 through the transmission mechanism 3. The output end of the reducer 4 drives the linkage mechanism 8 to move. Since the motor 2 and the reducer 4 are arranged side by side in the horizontal direction, the space utilization rate of the power unit in the horizontal direction is improved, so that the power unit does not occupy too much space in one direction. Therefore, the electric nail gun does not occupy too much space in one direction and will not obstruct the operator's line of sight during operation, making it more convenient for the operator to operate the electric nail gun.

[0051] The phrase "the reducer 4 and the motor 2 are arranged side by side in the horizontal direction" can be understood as the output shafts of the reducer 4 and the motor 2 being arranged side by side in the horizontal direction.

[0052] Specifically, motor 2 can be either a brushed motor or a brushless motor.

[0053] In one embodiment, the substrate 1 has a receiving cavity, and the transmission mechanism 3 is disposed in the receiving cavity so as to house the transmission mechanism 3 inside the substrate 1. This not only improves the space utilization of the substrate 1, but also protects the transmission mechanism 3.

[0054] In one embodiment, the substrate 1 includes:

[0055] Support base 11, support base 11 supports motor 2 and reducer 4; and

[0056] The cover plate 12 is placed on the side of the support base 11 away from the motor 2 and the reducer 4. The cover plate 12 and the support base 11 form a receiving cavity. That is, the base 1 is composed of the separately set support base 11 and cover plate 12. During installation, the motor 2 and reducer 4 can be installed on the support base 11 first, then the input end of the transmission mechanism 3 can be connected to the output end of the motor 2, then the output end of the transmission mechanism 3 can be connected to the input end of the reducer 4, and finally the cover plate 12 can be placed on the support base 11. This greatly reduces the installation difficulty of the motor 2, reducer 4 and transmission mechanism 3, and makes the installation of the motor 2, reducer 4 and transmission mechanism 3 more convenient.

[0057] See Figure 3 In one embodiment, the support base 11 is provided with a first positioning part 111 and a second positioning part 112. The first positioning part 111 and the second positioning part 112 are arranged side by side in the horizontal direction. The first positioning part 111 is connected to the motor 2 to play a role in installing and positioning the motor 2, so as to facilitate the quick and accurate installation of the motor 2 on the support base 11. The second positioning part 112 is connected to the reducer 4 to play a role in installing and positioning the reducer 4, so as to facilitate the quick and accurate installation of the reducer 4 on the support base 11.

[0058] See Figure 3 In one embodiment, the first positioning part 111 may have a positioning hole that cooperates with the motor 2, and the second positioning part 112 may have a positioning groove that cooperates with the end of the reducer 4 that is close to the support base 11.

[0059] Of course, in other embodiments, both the first positioning part 111 and the second positioning part 112 may be provided with positioning protrusions, as long as they can achieve the installation and positioning of the motor 2 and the reducer 4.

[0060] In one embodiment, the first positioning part 111 is provided with a first connecting hole 1111 and a first fastener 13. The head of the first fastener 13 abuts against the side of the first positioning part 111 near the cover plate 12. The rod of the first fastener 13 passes through the first connecting hole 1111 and is screwed to the motor 2 so as to reliably fix the motor 2 on the first positioning part 111.

[0061] The second positioning part 112 is provided with a second connecting hole 1121 and a second fastener 14. The head of the second fastener 14 abuts against the side of the second positioning part 112 near the cover plate 12. The rod of the second fastener 14 passes through the second connecting hole 1121 and is screwed to the reducer 4 so as to reliably fix the reducer 4 on the second positioning part 112.

[0062] To further improve the installation stability of the motor 2, in one embodiment, there are multiple first connecting holes 1111 and multiple first fasteners 13. The multiple first connecting holes 1111 are arranged in sequence around the output end of the motor 2, and the first fasteners 13 pass through the corresponding first connecting holes 1111 and are screwed together with the motor 2.

[0063] To further improve the installation stability of the reducer 4, in one embodiment, there are multiple second connecting holes 1121 and multiple fasteners 14. The multiple second connecting holes 1121 are arranged in sequence around the input end of the reducer 4, and the second fasteners 14 pass through the corresponding second connecting holes 1121 and are screwed together with the reducer 4.

[0064] See Figure 3 In one embodiment, the support 11 has a threaded hole;

[0065] The cover plate 12 has a third connecting hole 121;

[0066] Matrix 1 also includes:

[0067] The third fastener 15 has its head abutting against the side of the cover plate 12 away from the support base 11. The rod of the third fastener 15 passes through the third connecting hole 121 and is screwed into the threaded hole to reliably fix the cover plate 12 and the support base 11 together. The connection operation is convenient and the connection efficiency is high.

[0068] In one embodiment, there are multiple threaded holes, third connecting holes 121 and third fasteners 15. The third fasteners 15 pass through the corresponding third connecting holes 121 and are screwed to the corresponding threaded holes to further improve the connection stability between the cover plate 12 and the support base 11.

[0069] Of course, in other embodiments, the cover plate 12 and the support base 11 can also be connected together by snap-fitting, welding or other means.

[0070] See Figure 3 In one embodiment, the transmission mechanism 3 includes:

[0071] The drive gear 31 is sleeved on the output end of the motor 2 and can rotate with the output end of the motor 2.

[0072] Driven gear 32 and driving gear 31 are arranged side by side in the horizontal direction. Driven gear 32 meshes with driving gear 31 and is connected to the input end of reducer 4. That is, transmission mechanism 3 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.

[0073] See Figure 3 In one embodiment, the transmission mechanism 3 further includes:

[0074] An intermediate gear 33 is rotatably mounted on the base 1 and is located between the driving gear 31 and the driven gear 32. The driving gear 31 meshes with the driven gear 32 through the intermediate gear 33. Since the driving gear 31 meshes with the driven gear 32 through the intermediate gear 33, the power of the driving gear 31 can be transmitted to the driven gear 32 using the intermediate gear 33. At the same time, since the intermediate gear 33 is rotatably mounted on the base 1, it can support the driving gear 31 and the driven gear 32, thereby improving the assembly stability of the driving gear 31 and the driven gear 32 and thus further improving the transmission efficiency of the transmission mechanism 3.

[0075] Of course, in other embodiments, the transmission mechanism 3 may also adopt a chain drive mechanism 3, a belt drive mechanism 3, or other transmission structures.

[0076] See Figure 2 In one embodiment, the power unit of the electric nail gun further includes:

[0077] Connecting seat 5 is located on the side of motor 2 and reducer 4 away from base 1. Connecting seat 5 connects motor 2 and reducer 4 to further improve the assembly stability of motor 2 and reducer 4. Connecting seat 5 is used to connect with housing 20 of electric nail gun so as to facilitate the installation of power unit on electric nail gun.

[0078] See Figure 2 The connecting seat 5 has a clearance opening 51 that passes through the connecting seat 5. The end of the motor 2 away from its output end is provided with a cooling fan 7. The cooling fan 7 is located in the clearance opening 51 so that the heat generated by the motor 2 during operation can be diverted to the outside through the clearance opening 51 to achieve efficient heat dissipation of the motor 2 and ensure that the motor 2 can operate reliably.

[0079] See Figure 2 The power unit also includes:

[0080] Bearing 6 is mounted on connecting seat 5. The output end of reducer 4 passes through the inner ring of bearing 6 and can rotate with the inner ring of bearing 6 to support the output end of reducer 4, while reducing the friction of the output end of reducer 4, thereby making the output end of reducer 4 rotate more smoothly and reducing the energy consumption caused by friction.

[0081] See Figure 1 A preferred embodiment of this utility model provides an electric nail gun, including the power device of the electric nail gun described above.

[0082] The electric nail gun of this utility model, due to the adoption of the above-mentioned power device, and the fact that the motor 2 and the reducer 4 are arranged side by side in the horizontal direction, improves the space utilization rate of the power device in the horizontal direction, so that the power device does not occupy too much space in one direction, thus making the electric nail gun more convenient for the operator to hold.

[0083] See Figures 6-10 In one embodiment, the electric nail gun further includes:

[0084] Housing 20, housing 20 is connected to the connecting seat 5 of the power unit;

[0085] Push rod 9 is movably mounted on housing 20;

[0086] The linkage mechanism 8 has its input end connected to the output end of the reducer 4 and its output end connected to the push rod 9. The output end of the linkage mechanism 8 can reciprocate along the moving direction of the push rod 9 under the action of the output end of the reducer 4, so as to drive the push rod 9 to move on the housing 20.

[0087] See Figures 7-10 In one embodiment, the linkage mechanism 8 includes:

[0088] The first link 81 is connected to the output end of the reducer 4 and can rotate with the output end of the reducer 4.

[0089] The second link 82 has its first end rotatably connected to the first link 81, and its second end rotatably connected to the push rod 9. When the first link 81 rotates with the output end of the reducer 4, the first link 81 drives the first end of the second link 82 to rotate, thereby causing the second end of the second link 82 to move along the direction of the push rod 9, thus moving the push rod 9. By driving the push rod 9 to move through the first link 81 and the second link 82, the nail can be quickly clamped. Simultaneously, the linkage of the first link 81 and the second link 82 converts the rotation of the reducer 4's output end into linear motion. This linear motion is relatively stable and does not cause a decrease in accuracy due to wear on the first link 81 and the second link 82.

[0090] See Figures 7-10 In one embodiment, the housing 20 has a guide groove 201 that extends along the moving direction of the push rod 9.

[0091] Electric nail guns also include:

[0092] A limiting member 10 is mounted on the push rod 9 and is rotatably connected to the second end of the second connecting rod 82. A portion of the limiting member 10 is placed within the guide groove 201 and is slidably engaged with it. During the movement of the limiting member 10 driven by the second connecting rod 82, in addition to the force acting in the direction of the push rod 9's movement, there are also forces acting in the up, down, left, and right directions, which could cause the push rod 9 to rotate or swing during use. The engagement of the limiting member 10 with the guide groove 201 of the housing 20 effectively limits the movement of the limiting member 10, ensuring that the push rod 9 does not swing or rotate, thus improving the stability and service life of the electric nail gun.
