Description

Technical Field

[0001] The utility model relates to the technical field of drive controllers, in particular to an upper cover of a drive controller. Background Art

[0002] The controller is a main command device that changes the wiring of the main circuit or control circuit and the resistance value in the circuit in a predetermined order to control the start, speed regulation, braking and reverse of the motor. The housing of the controller is composed of an upper cover and a lower cover that matches the upper cover. Figure 4 , Figure 5 , Figure 6 As shown, in the prior art, the upper cover of the controller housing is formed by injection molding. Since the side wall of the upper cover itself is thinner than the thickness of the bolt installation part and there is a gradient difference in the cooling molding of the injection molding fluid, the side wall of the molded upper cover is thinner or the deformation of the side wall of the upper cover is larger, which makes the upper cover easy to break. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the problem that in the prior art, the upper cover of the controller housing is formed by injection molding, and since the side wall of the upper cover itself is thinner than the bolt installation part and there is a gradient difference in the cooling molding of the injection molding fluid, the side wall of the molded upper cover is thinner or the side wall of the upper cover is deformed, resulting in the upper cover being easy to break, a drive controller upper cover is provided.

[0004] The utility model solves the technical problem by adopting a technical solution: a driving controller upper cover, comprising a cover body and a mounting portion,

[0005] The cover body includes a main board and a side board surrounding the main board. The side board is fixedly connected to the side edge of the main board. A receiving groove for accommodating the bolt head is formed on the outer side of the main board of the cover body.

[0006] The mounting portion is provided with a mounting hole for the bolt rod to pass through, the mounting hole is communicated with the accommodating groove, and a molding gap exists between the mounting portion and the side plate close to it. By setting a molding gap between the mounting portion and the side plate of the cover body, the glue injection path of the upper cover is changed, so that the mounting portion and the side plate of the cover body can be cooled and formed independently during the molding process without connection, thereby ensuring the molding effect of the upper cover and avoiding deformation of the upper cover.

[0007] In order to solve the problem of difficulty in aligning the mounting part of the upper cover and the mounting part of the lower cover and low connectivity, the mounting part further includes a mounting groove on an end surface of one side away from the mainboard, and the mounting groove is connected to the mounting hole.

[0008] It further comprises that the mounting groove, the mounting hole and the accommodating groove are all coaxially arranged.

[0009] In order to solve the problem that the installation part occupies a large space, the installation part further includes a notch on one side close to the side plate, and the notch is connected to the molding gap.

[0010] The beneficial effect of the utility model is that a drive controller upper cover provided by the utility model changes the glue injection path of the upper cover by setting a molding gap between the mounting portion and the side plate of the cover body, so that the mounting portion and the side plate of the cover body can be independently cooled and molded during the molding process without connection, thereby ensuring the molding effect of the upper cover and avoiding deformation of the upper cover.

[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] like Figure 1 This is a structural diagram of the utility model, a drive controller cover, including a cover body 1 and a mounting portion 2,

[0021] like Figure 3As shown, the cover body 1 includes a main board 11 and a side board 12 surrounding the main board 11. The side board 12 is fixedly connected to the side edge of the main board 11. A receiving groove 13 for receiving the bolt head is formed on the outer side of the main board 11 of the cover body 1. The receiving groove 13 can receive the bolt head to prevent the bolt head from being exposed and causing wear during use.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, a mounting hole 21 for the bolt rod to pass through is opened on the mounting portion 2, and the mounting hole 21 is connected to the receiving groove 13. A molding gap 3 exists between the mounting portion 2 and the side plate 12 it is close to, thereby changing the glue injection path of the upper cover, so that the mounting portion 2 and the side plate 12 of the cover body 1 can be cooled and molded independently during the molding process without connection, thereby ensuring the molding effect of the upper cover and avoiding deformation of the upper cover.

[0023] The mounting portion 2 has a mounting groove 22 on its end face away from the mainboard 11. The mounting groove 22 is used to cooperate with the protrusion on the lower cover, so that the upper cover and the lower cover can be docked conveniently and quickly, and the connection strength between the upper cover and the lower cover can be enhanced. The mounting groove 22 is connected to the mounting hole 21, and the mounting groove 22, the mounting hole 21 and the accommodating groove 13 are all coaxially arranged.

[0024] like Figure 2 , Figure 3 As shown, a notch 23 is provided on the side of the mounting portion 2 close to the side plate 12, and the notch 23 is connected to the molding gap 3. The notch 23 plays an avoidance role. On the one hand, it avoids the need to move the position of the mounting portion 2, and on the other hand, it can further increase the molding gap 3, thereby reducing the impact of the mounting portion 2 on the side plate 12 of the upper cover during the cooling process.

[0025] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
