Technical Field
[0001] The utility model relates to the field of motor controllers, in particular to a spring sheet structure used for a motor controller and a processing die thereof. Background Art
[0002] The motor controller is an integrated circuit that actively controls the motor to operate in a set direction, speed, angle, and response time.
[0003] In the interior of the motor controller, it is generally necessary to fix the pipeline with a spring clip. Generally, the pipeline and the ceramic substrate are fixed to the bottom plate through the spring clip. Due to the certain difference in size between the pipeline and the spring clip, the pipeline will be offset in some application scenarios. At the same time, during the pressing process, the bottom pipeline is prone to be subjected to excessive pressing pressure and deformation, which will cause the pipeline to be damaged and reduce the service life of the pipeline.

It solves the problem that there is a size difference between the existing pipeline and the spring clip, which causes the pipeline to shift in some application scenarios. At the same time, during the pressing process, the bottom pipeline is easily subjected to excessive pressing pressure, deformation, etc., thereby causing the pipeline to be damaged.

DETAILED DESCRIPTION
[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figure 1 , Figure 2 and Figure 5 The utility model provides a technical solution: a spring structure for a motor controller, comprising a shell 1, a pressing assembly 200 is installed on the front of the shell 1, and the shell 1 and the pressing assembly 200 are used in coordination with each other, and the length of the spring structure, the two arc curves and other specific dimensions are adjusted to take into account the pressing and fixing effect and the service life, while controlling the pressing force to avoid deformation of the pipe below, and the notch on the spring is used to distinguish left and right.
[0033] In this embodiment, the pressing assembly 200 is a structure for pressing the elastic force to limit the movement of the pipe.
[0034] like Figure 1 , Figure 2 and Figure 5 As shown, the pressing assembly 200 includes a fixing mechanism installed on the front side of the housing 1 and an auxiliary mechanism installed inside the pressing assembly 200 .
[0035] The fixing mechanism includes mounting columns 201 fixed on the left and right sides of the shell 1 and arranged at equal distances, pads 202 fixed on the front of the shell 1 and arranged at equal distances, a pipeline 206 placed inside the pad 202, a spring body 203 abutting against the front of the pipeline 206, a bolt 205 threadedly connected to the top of the mounting column 201, and a gasket 204 placed on the front of the spring body 203.
[0036] The auxiliary mechanism includes an arc-shaped slot 207 provided inside the cushion block 202 , a threaded hole 208 provided on the front of the spring body 203 , and a notch 209 provided on the front of the spring body 203 for distinguishing between the left and right sides.
[0037] It should be noted that the front sides of the plurality of mounting columns 201 are provided with threaded grooves for threaded connection of the bolts 205 , and the front sides of the gaskets 204 are provided with threaded through holes, so that the bolts 205 can be threadedly connected in the threaded grooves, so that the gaskets 204 and the spring clip body 203 are fixed, and then the pipeline 206 is fixed through the spring clip body 203 .
[0038] In addition, the diameter of the bolt 205 is equal to the diameter of the threaded through hole, the threaded groove and the threaded hole 208. The spring clip body 203 is wavy, which allows the bolt 205 to be installed normally to prevent it from being too large or too small to be installed. The spring clip body 203 is wavy, mainly because the length of the spring clip structure, the specific dimensions of the two arc curves, etc. are adjusted to take into account the pressing and fixing effect and service life, while controlling the pressing force to avoid deformation of the pipeline 206 below.
[0039] At the same time, ten mounting columns 201 are fixedly connected to the left and right sides of the shell 1, and two adjacent mounting columns 201 form a group, with a total of five groups on each side. The five spring body bodies 203 on the left and right sides can be threadedly fixed through the mounting columns 201 on the left and right sides to make them stable.
[0040] Secondly, the pad 202 is located on the back of the spring body 203, and the spring body 203 presses on the front of the pipeline 206. The pipeline 206 can be placed inside the pad 202, and the top of the pipeline 206 is exposed. Then, the spring body 203 is clamped on the pipeline 206 through the notch of the spring body 203 to press the pipeline 206.
[0041] See also Figure 1-5 The utility model also provides a technical solution: a processing mold, including a mold assembly 300 and the above-mentioned spring structure for a motor controller, the mold assembly 300 includes a mold plate 301, a positioning column 303 fixed to the front of the mold plate 301 for positioning, and a processing part 302 fixed to the front of the mold plate 301 for producing and processing the spring body.
[0042] In this embodiment, the mold assembly 300 is a structure for continuously producing spring pieces.
[0043] It should be noted that the size of the processed part 302 is compatible with the size of the spring clip body 203. The size matching can make the manufactured spring clip body 203 of appropriate size and easy to use. A through hole is opened on the front of the mold plate 301. Through the use of the through hole, a hole can be opened in the spring clip body 203 during the manufacturing process, so that it is easy to install it on the front of the mounting column 201 through the bolt 205.
[0044] The working principle of the above embodiment is as follows: when the spring clip structure of the motor controller is used, the pipeline 206 is first clamped in the arc-shaped clamping groove 207 inside the cushion block 202, and then the spring clip body 203 is placed on the front of the mounting column 201 of the same group in turn, and then the gasket 204 for fixing is placed, so that the threaded through hole, the threaded groove and the threaded hole 208 are aligned, and then the bolt 205 is passed through in turn and threadedly connected to the threaded groove inside the mounting column 201, so that the spring clip body 203 and the gasket 204 are fixed. Through the set gasket 204, the bolt 205 will not be separated due to the influence of vibration during the later use. At the same time, the notch on the back of the spring clip body 203 is pressed on the front of the pipeline 206. At the same time, five groups are set on each of the left and right sides, so that the pipeline 206 can be fixed, which improves the pressing and fixing effect and service life, and at the same time controls the pressing force to avoid deformation of the pipeline 206 below.
[0045] Secondly, by using the mold assembly 300, the spring sheet body 203 can be continuously produced and manufactured, and can be used for continuous processing and manufacturing of the spring sheet.
[0046] Compared with the prior art, the shell 1 and the pressing assembly 200 are used in coordination with each other, and the length of the spring structure, the specific dimensions of the two arc curves and the like are adjusted to take into account both the pressing and fixing effect and the service life. At the same time, the pressing force is controlled to avoid deformation of the lower pipeline 206. At the same time, the notch on the spring is used to distinguish between left and right. Secondly, the mold assembly 300 is used to continuously process and manufacture the spring, which solves the problem that the existing pipeline 206 and the spring have different sizes, causing the pipeline 206 to shift in some application scenarios. At the same time, during the pressing process, the bottom pipeline 206 is easily subjected to excessive pressing pressure, resulting in deformation and the like, thereby causing the pipeline 206 to be damaged.
