Description

Technical Field

[0001] The utility model relates to the technical field of motor springs, in particular to a linear motor spring structure and a linear motor thereof. Background Art

[0002] As the name suggests, a linear motor spring is a spring used in linear motors. A linear motor is a transmission system developed using magnetic suspension technology that combines rotary and linear motion. Its core principle is to reduce or even eliminate friction between the two contact surfaces of the moving pair through the "magnetic levitation" principle of two magnets with the same poles repelling each other, thereby achieving a driving effect with only minimal force. The linear motor spring plays a role in causing magnetic resonance in this transmission system and is a key component in generating vibration effects.

[0003] Currently, patent document CN214506849U discloses a spring sheet and a linear motor having the same. Specifically, the invention discloses combining two spring sheets into one to form a U-shaped structure. The spring is typically mounted and fixed in the motor by welding. During actual installation, the spring sheet only requires a single assembly and welding process. This single welding process simplifies the process compared to a double spring assembly, improving production efficiency, reducing costs, and ultimately increasing economic benefits.

[0004] However, there are currently the following problems in the installation and use of linear motor springs: they can only adapt to a small frequency and can usually only work normally within a limited frequency range. Exceeding this range may cause performance degradation or failure, thereby limiting the applicability of linear motor springs in different application scenarios. They also have high requirements for the installation position. Excessive deviation in the installation position or improper installation may affect the normal working performance of the spring and affect its use;

[0005] In view of this, we propose a linear motor spring structure and a linear motor thereof. Utility Model Content

[0006] The purpose of the present utility model is to provide a linear motor spring structure and a linear motor thereof, so as to solve the problems in the above background such as complex structure, low adaptability to frequency and high requirements on installation position.

[0025] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figures 1-6 As shown, the utility model is a linear motor spring structure, including a spring assembly 1;

[0027] It should be explained that the spring assembly 1 is formed entirely by stamping from a thin sheet. By using a stamping process, the raw material can be quickly processed into the desired shape. Through the precise design of the mold and the accurate control of the punch press, spring assemblies 1 with consistent shape and precise dimensions can be produced in large quantities and efficiently. The thin sheet design allows the spring assembly 1 to have a more compact structure and lighter weight while maintaining sufficient strength and elasticity.

[0028] Furthermore, due to the uniform deformation of the material during the sheet stamping process, the spring assembly 1 can distribute stress more evenly when subjected to force, reducing the phenomenon of local stress concentration, thereby improving the vibration fatigue life and overall performance of the spring assembly 1;

[0029] The spring assembly 1 includes a first arm 101 and a second arm 102. The length of the first arm 101 is greater than that of the second arm 102, and the first arm 101 and the second arm 102 are Y-shaped as a whole.

[0030] The first arm 101 and the second arm 102 are integrally arranged into a Y shape (such as Figure 3When subjected to force, the "Y"-shaped structure can disperse stress more evenly, reducing the phenomenon of local stress concentration, thereby extending the vibration fatigue life. At the same time, the "Y"-shaped structure also optimizes the vibration characteristics, thereby being able to adapt to a wider range of vibration frequencies and reducing noise during vibration.

[0031] At the same time, the first arm 101 is longer than the second arm 102, so as to facilitate installation and increase the flexibility of the structure;

[0032] A first through-going notch 1011 is formed on the outer surface of the first arm 101. A first positioning portion 1012 is formed on the lower side of the first arm 101. The first positioning portion 1012 is formed as a semi-arc-shaped notch. The first arm 101 has two bending points.

[0033] Specifically, the first arm 101 is first bent to the left, and the bending point is as follows: Figure 1 At A shown in FIG, a basic support structure is formed, where the first arm 101 is located as shown in FIG. Figure 1 After bending at the bending point A in Figure 1 An additional fine bending point is added at B shown in the figure, which can enhance the stability of the entire structure.

[0034] In such Figure 1 A first notch 1011 is provided at the upper end of the bending point B shown in the figure. The first notch 1011 runs through the first arm 101 to facilitate precise fit with the mass 2. In addition, a circular notch is designed at the top of the first arm 101. This notch is not only used to connect the mass 2 but also plays a key positioning role, thereby ensuring the stability of the mass 2 during vibration.

[0035] A penetrating second notch 1021 is formed on the outer surface of the second arm 102, a second positioning portion 1022 is formed on the lower side of the second arm 102, and the second arm 102 is provided with two bending points;

[0036] Specifically, the second arm 102 is bent to the right, and the bending point is as follows: Figure 1 At C shown in FIG, another branch of the "Y" structure is formed. Figure 1 After the bending at C shown in FIG, a bending is also added at the front end of the second arm 102. The bending point is as shown in FIG. Figure 1 D as shown, and a second notch 1021 is opened at the upper end of the bending point D, so as to facilitate connection with the housing 3. It should be noted that a flat plate position is reserved on the lower side of the second arm 102, and the flat plate position is the second positioning point 1022. This second positioning point 1022 is used for positioning and connecting with the housing 3, thereby enhancing the stability and reliability between the entire spring assembly 1 and the housing 3;

[0037] The first arm 101 and the second arm 102 are provided with reinforcing ribs, and the direction of the reinforcing ribs is along the bending direction, and the provided reinforcing ribs are used to enhance the structural strength and stability of the spring assembly 1 when subjected to force;

[0038] A lubricating coating is provided on the side walls of the first notch 101 and the second notch 1021. The lubricating coating is used to reduce friction with the moving parts of the linear motor, improve movement efficiency and reduce noise;

[0039] Example 2: A linear motor, which is elastically supported and guided by the spring assembly 1, thereby improving overall working efficiency and reliability;

[0040] The working principle of the present invention is as follows: When the spring assembly 1 is installed, (the exemplary installation result is as follows Figure 4 - Figure 6 The specific process is as follows:

[0041] Align the mass block 2 with the first notch 1011 on the outer surface of the first arm 101. It should be noted that during installation, the positioning hole or structure on the mass block 2 should be precisely aligned with the first notch 1011 and the circular notch at the first positioning point 1012 on the first arm 101. This can enhance positioning and installation stability during installation. Push the mass block 2 into the first notch 1011 until it is fully embedded and stably fixed on the first arm 101. During the fixing process, ensure that the first arm 101 is stable and will not fall off due to vibration.

[0042] It is worth noting that after the mass block 2 is connected to the first arm 101, a fixing member (such as a pin or glue) can be added to further increase stability.

[0043] Align the second positioning portion 1022 on the lower side of the second support arm 102 with the corresponding slot on the housing 3 (as shown in FIG. Figure 4 As shown), it is worth noting that it is necessary to ensure that the second positioning portion 1022 is completely in contact with the positioning surface of the housing 3 to enhance the stability and reliability of the connection, and then tighten the second arm 102 to the housing 3 to avoid damage to components or looseness that affects performance due to over-tightening.

[0044] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
