Description

Technical Field

[0001] The utility model relates to the technical field of AC drivers, in particular to an AC driver which is easy to move. Background Art

[0002] An AC drive is a commonly used device for driving a servo motor, and mainly includes a host computer. The host computer includes a housing, a network cable slot and other structures, and is an existing technology.

[0003] After searching, it was found that in the prior art, such as the Chinese patent (grant number: CN220173652U), an AC servo driver is disclosed. The driver board is fixed in an internal space through the provided connection seat and air holes, sufficient heat dissipation space is reserved, and a heat conductive sheet is used for heat transfer. At the same time, a heat dissipation fan is used for rapid ventilation and heat dissipation to avoid heat accumulation in the driver to generate high temperature, thereby improving the service life and heat dissipation effect of the driver.

[0004] However, the above-mentioned patent does not have a portable structure. If the entire drive needs to be moved, the staff needs to hold the drive with both hands and move the drive through the friction between the hands and the drive. This is very laborious and inconvenient. Therefore, improvements are needed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides an AC driver that is easy to move. By arranging a handheld device in the heat dissipation hole, the problem that the existing AC driver is not easy to move is solved.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] In order to facilitate the insertion of fingers into the mounting ring, a plurality of finger grooves arranged in a circular array are provided on the inner wall of the outer end of the mounting ring, and the finger grooves are arranged in a semicircular shape.

[0009] In order to facilitate the storage of the wires, the outer surface of the outer end of the mounting ring extends outward to form a circular convex ring, and a winding spacing is left between the convex ring and the outer shell of the host. If the excess wire connecting the host and the servo motor is too long, the wire can be wound within the winding spacing.

[0010] When the host is laid down for use, in order to ensure the stable operation of the host, the heat dissipation hole is opened at the center of the side of the shell of the host, and the convex ring supports the host, and the center of gravity is concentrated on the convex ring, so that the host will not fall over easily.

[0011] When the host is laid down for use, in order to ensure normal heat dissipation, a plurality of heat dissipation grooves arranged in a circular array are provided on the outer ring surface of the convex ring, and both ends of the heat dissipation grooves are open. The heat dissipation grooves are connected to the inside of the host, which can ensure normal heat dissipation of the host.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the installation ring is convenient for fingers to be inserted while ensuring normal heat dissipation of the host, and the staff can insert their hands into the finger grooves on the two installation rings to facilitate moving the host, and the structure is simple and practical.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 , Figure 4As shown, the utility model provides an AC driver that is easy to move, including a host 1. The host 1 is a prior art, including a shell, a network cable slot and other structures. More specific principles are not repeated in the utility model. The technical content disclosed in the Chinese patent (authorization number: CN220173652U) can be referred to. Circular heat dissipation holes are opened on both sides of the shell of the host 1, and a portable device is installed in the heat dissipation hole. The portable device includes a mounting ring 2 that can be detachably installed in the heat dissipation hole. In order to realize the disassembly and assembly of the mounting ring 2, the mounting ring 2 is threadedly connected in the heat dissipation hole, and a filter 3 is fixed at the inner end of the mounting ring 2, and the outer end extends out of the host 1.

[0021] like Figure 2 As shown, in order to facilitate the insertion of fingers into the installation ring 2, a plurality of finger grooves 3-1 arranged in a circular array are provided on the inner wall of the outer end of the installation ring 2. The finger grooves 3-1 are semicircular in shape. The staff inserts their two hands into the finger grooves 3-1 in the convex ring 4 to prevent the fingers from sliding in the convex ring 4, so that the host 1 can be moved with both hands.

[0022] like Figure 4 As shown, in order to facilitate the storage of the wires, the outer surface of the outer end of the mounting ring 2 extends outward to form a circular convex ring 4, and a winding spacing is left between the convex ring 4 and the outer shell of the host 1. If the excess wire connecting the host 1 and the servo motor is too long, the wire can be wound within the winding spacing.

[0023] like Figure 1 As shown, when the host 1 is laid down for use, in order to ensure the stable operation of the host 1, a heat dissipation hole is opened at the center of the side of the shell of the host 1. When the host 1 is laid down for use, the convex ring 4 supports the host 1, and the center of gravity is concentrated on the convex ring 4, so that the host 1 will not fall over easily. The heat dissipation groove 4-1 is connected to the inside of the host 1, which can ensure normal heat dissipation of the host 1.

[0024] like Figure 3 As shown, when the host 1 is laid down for use, in order to ensure normal heat dissipation, a plurality of heat dissipation grooves 4-1 arranged in a circular array are provided on the outer ring surface of the convex ring 4, and the heat dissipation grooves 4-1 are open at both ends. When the host 1 is laid down for use, the heat dissipation grooves 4-1 are connected to the inside of the host 1, which can ensure normal heat dissipation of the host 1.

[0025] The working principle of the utility model is described in detail below: when the host 1 is used vertically, the mounting ring 2 is screwed into the heat dissipation hole. The filter 3 can ensure heat dissipation and prevent dust from entering the inside of the host 1. If the excess wire connecting the host 1 and the servo motor is too long, the wire can be wound within the winding spacing, and the excess wire can be wound to prevent clutter. When the host 1 needs to be moved, the staff's two hands are inserted into the finger groove 3-1 in the convex ring 4 to prevent the fingers from sliding in the convex ring 4. In this way, the host 1 can be moved with both hands. When the host 1 is laid down for use, the convex ring 4 supports the host 1, and the heat dissipation groove 4-1 is connected to the inside of the host 1, which can ensure normal heat dissipation of the host 1. When the dust on the filter 3 needs to be cleaned, the mounting ring 2 is rotated toward the outside of the heat dissipation hole until the mounting ring 2 is unscrewed from the heat dissipation hole, and the dust on the filter 3 can be cleaned. After cleaning, the mounting ring 2 can be screwed into the heat dissipation hole.

[0026] Finally, the most important contribution of the present invention compared with the prior art is that the mounting ring 2 is convenient for fingers to be inserted while ensuring normal heat dissipation of the host 1. The staff can insert their hands into the finger grooves 3-1 on the two mounting rings 2 to facilitate moving the host 1. The structure is simple and the practicability is high.

[0027] In summary, the portable device is convenient for carrying the host 1, ensures normal heat dissipation of the host 1 in the upright state and the laid-down state, and is convenient for winding the wires, and has a certain degree of creativity.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
