Description

Technical Field

[0001] This utility model relates to a vehicle braking system device, and more particularly to an electromagnet positioning and fixing device therein. Background Technology

[0002] Electromagnets play an irreplaceable role in trolley braking systems. They provide stable braking force, and the non-contact force transmission and control improve the system's reliability and durability. At the same time, by energizing and de-energizing, they can achieve rapid action and quickly respond to braking commands, thereby significantly improving trolley safety and reducing the risk of accidents.

[0003] Meanwhile, the assembly and positioning of electromagnets in vehicle braking systems is a crucial aspect of tram braking systems. Its significance lies not only in ensuring braking and safety performance but also in improving system reliability, energy efficiency, and intelligence. Inaccurate positioning affects the electromagnet's attraction force; insufficient positioning accuracy with other mating components leads to uneven air gaps or misalignment, resulting in unstable braking effects or insufficient braking force. Positioning misalignment or loosening reduces the reliability of the braking system and can even cause safety hazards. Precise assembly and positioning maximizes the electromagnet's effectiveness, ensuring the safe and efficient operation of trams.

[0004] In existing technologies, the electrical connection of electromagnets is typically assembled manually by adding conductive wires. This is understandably problematic because manual operation introduces errors, leading to issues such as insufficient positioning accuracy, poor assembly consistency, difficulty in achieving automated mechanical assembly, and even weak electrical connections. This not only increases the assembly cost of vehicle components but also poses potential safety hazards regarding the reliability of critical component assembly.

[0005] In order to overcome the above-mentioned defects in the existing technology, there is an urgent need in the field for a positioning and fixing device for electromagnets in vehicle brakes, which is used for assembling and fixing electromagnets in vehicle braking systems, accurately positioning the assembly position of the electromagnets, providing reliable electrical connections, meeting the structural requirements of automated mechanical production, reducing assembly costs, and improving the reliability of braking system components.

Although the description of this utility model will be presented in conjunction with preferred embodiments, this does not mean that the features of this utility model are limited to this embodiment. On the contrary, the purpose of describing the utility model in conjunction with the embodiments is to cover other options or modifications that may be derived based on the claims of this utility model. To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description.

[0047] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0048] Furthermore, the terms "upper," "lower," "left," "right," "top," "bottom," "horizontal," and "vertical" used in the following description should be understood as the orientations shown in the relevant paragraphs and accompanying drawings. These relative terms are for illustrative purposes only and do not imply that the described device must be manufactured or operated in a specific orientation; therefore, they should not be construed as limiting the scope of this invention.

[0049] It is understood that although terms such as "first," "second," and "third" may be used herein to describe various components, regions, layers, and / or parts, these components, regions, layers, and / or parts should not be limited by these terms, and these terms are only used to distinguish different components, regions, layers, and / or parts. Therefore, the first component, region, layer, and / or part discussed below may be referred to as the second component, region, layer, and / or part without departing from some embodiments of this utility model.

[0050] In order to overcome the above-mentioned defects in the existing technology, this utility model provides a positioning and fixing device for a vehicle brake electromagnet, which is used for assembling and fixing the electromagnet in the vehicle braking system. It accurately positions the assembly position, provides a reliable electrical connection, meets the structural requirements of automated mechanical production, reduces assembly costs, and improves the reliability of braking system components.

[0051] The positioning and fixing device for the vehicle brake electromagnet provided by this utility model includes: an upper housing, a lower housing, and an electric needle. The upper housing and the lower housing are assembled together to form a cavity. The electromagnet is fixedly installed in the cavity. The electric needle is fixed on the upper housing. The first end of the electric needle is configured to be inserted into a circuit board, and the second end of the electric needle is configured to be inserted into the electrical interface of the electromagnet.

[0052] Understandably, fixing the electromagnet in the cavity formed by the upper and lower housings can prevent the electromagnet from moving, thus fixing and accurately defining its assembly position, thereby ensuring the stability and reliability of the braking operation.

[0053] In a preferred embodiment, the electric needle in the electromagnet positioning and fixing device provided by this utility model is an L-shaped electric needle.

[0054] The following explanation, in conjunction with the illustrations, will provide a more detailed account.

[0055] Figure 1 This is an exploded view of the positioning and fixing device for an electromagnet, according to an embodiment of the present invention.

[0056] Please refer to Figure 1 The positioning and fixing device for an electromagnet provided by this utility model includes: an upper housing 101, a lower housing 102, and an L-shaped electric needle 103 that are assembled together. The upper housing 101 and the lower housing 102 form a cavity, and the electromagnet 104 is fixedly assembled in the cavity. A circuit board 105 is pressed onto the top of the positioning and fixing device.

[0057] Figure 2 This is a schematic diagram of the electromagnet positioning and fixing device according to an embodiment of the present invention, showing the circuit board pressed onto the top after assembly.

[0058] Can be combined Figure 2 and Figure 1 The movable rod of the electromagnet 204 extends from the end of the cavity to connect to the mechanical moving parts. The L-shaped electric needle 203 is fixedly connected to the upper housing 201, and the first end of the L-shaped electric needle 203 passes through the upper housing 201 and is inserted from bottom to top into the upper circuit board 205. It can be understood that the circuit board can be connected to a controller to realize electrical control, thereby integrating functional components.

[0059] Those skilled in the art should understand that during the assembly of braking components, if there is free space for the positioning and assembly of the electromagnet, it can easily lead to displacement of the parking position or even safety hazards. The positioning and fixing device for the electromagnet provided by this utility model confines the electromagnet in the cavity composed of the upper and lower housings, effectively limiting the movement space of the electromagnet, thereby playing the role of accurate positioning and improving the reliability of the electronically controlled braking components.

[0060] In a preferred embodiment of this utility model, the upper housing uses the electric needle as an insert and is formed by insert injection molding.

[0061] Figure 3 This is an anatomical diagram illustrating the structure of the upper housing and L-shaped electric needle in a positioning and fixing device for an electromagnet, according to an embodiment of the present invention. Figure 4 This is a schematic diagram of the structure of an electromagnet positioning and fixing device according to an embodiment of the present invention, in which the upper housing is injection molded with an L-shaped electric needle as an insert.

[0062] In a preferred embodiment, such as Figure 4 As shown, and can also be referenced. Figure 3After the insert is injection molded, the upper housing 302 covers the bent portion of the L-shaped electric needle 301 to form a fixed connection. It is easy to understand that by covering the bent portion of the L-shaped electric needle 301 into the upper housing 302 through insert injection molding, the position between the electric needle and the upper housing can be fixed, thereby achieving a better positioning effect.

[0063] It should be noted that, in this embodiment, an L-shaped electric needle is preferably used to clearly illustrate the device structure of the preferred embodiment of this utility model, rather than to limit the scope of protection of this utility model. Understandably, compared to a typical straight electric needle, an L-shaped electric needle is easier to position and fix, thereby improving the accuracy of the device's positioning function. In practical applications, electric needles of other shapes can also be used to achieve similar effects; all can be applied to the electromagnet positioning and fixing device provided by this utility model, and all should be included within the scope of protection of this utility model.

[0064] Further, please refer to Figure 4 The first end of the L-shaped electric needle 301 passes through the upper housing 302 from bottom to top and is then inserted into the circuit board above. Figure 4 (Not shown in the image), and at the same time, the second end of the L-shaped electric needle 301 extends laterally below the upper housing 302 to connect to the electrical interface of the electromagnet. It can be understood that the L-shaped electric needle 301 and the upper housing 302 form a fixed position assembly, improving the assembly positioning accuracy.

[0065] Figure 5 This is a schematic diagram illustrating the connection and assembly between the L-shaped electric needle and the electromagnet's electrical interface in a positioning and fixing device for an electromagnet, according to an embodiment of this utility model. It should be noted that this diagram is designed to more clearly demonstrate the electrical connections between the components. Figure 5 The schematic diagram of the upper shell device structure is omitted.

[0066] You can refer to the following: Figure 5 ,exist Figure 4 In the illustrated embodiment, the L-shaped electric needle 301 is positioned and / or extended on the upper housing 302 such that the second end extends laterally below the upper housing 302 to fit into the electromagnet's electrical interface. The mounting structure below the upper housing mates with the electromagnet's mounting structure, and the second end of the L-shaped electric needle can be inserted into the electromagnet's electrical interface, thus positioning the electromagnet.

[0067] Easy to understand, can form Figure 5 The second end of the L-shaped electric needle shown is connected to the electrical assembly structure in the electromagnet electrical interface 502. Compared with the existing technology that uses a conductive wire connection, this electrical connection structure improves the reliability of the electrical connection, facilitates automated mechanical production, and makes it easier to achieve consistent production requirements.

[0068] In a preferred embodiment of the present invention, the first end of the electric needle is provided with a fisheye-shaped tip for insertion into the electrical interface of the circuit board.

[0069] In a preferred embodiment of the present invention, the electric needle has a limiting portion at the first end near the tip to limit the depth to which the circuit board is inserted into the electric needle.

[0070] The following description, using the example of an L-shaped electric needle, will further elaborate on the structure of the electromagnet positioning and fixing device provided by this utility model.

[0071] Please continue to refer to this. Figure 4 In a preferred embodiment of this utility model, the first end of the L-shaped electric needle 301 is provided with a fisheye-shaped tip 3011 for insertion into the electrical interface of the circuit board. (See reference...) Figure 2 ,like Figure 2 As shown, during the process of pressing the circuit board 205 onto the top of the positioning and fixing device, the fish-eye-shaped tip deforms to form an interference fit with the circuit board 205, ensuring the reliable performance of the electrical connection between the electric needle and the circuit board.

[0072] Furthermore, even better, such as Figure 4 As shown, the L-shaped electrode 301 has a limiting part 3012 at the first end near the tip to limit the insertion depth of the circuit board into the L-shaped electrode. Through detailed design of the electrode structure, assembly reliability is increased while ensuring accurate assembly positioning.

[0073] In one embodiment, the number of the electric needles is configured to match the number of the electromagnet and the electrical interface of the circuit board.

[0074] Please continue to refer to this. Figure 5 In the positioning and fixing device for the electromagnet provided by this utility model, the number of L-shaped electric needles 501 is configured to match the number of electric interfaces 501 of the electromagnet. At the same time, it is easy to understand that it also matches the number of electric interfaces on the circuit board that are connected to the first end of the electric needle.

[0075] In the illustrated embodiment of this utility model, the positioning and fixing device for the electromagnet provided by this utility model consists of two L-shaped electric needles. In practical applications, the number and position of the electric needles can be adaptively adjusted according to different specific application components. This embodiment is only provided as an example to clearly illustrate the structural design and assembly relationship between the electric needle structure and the positioning and fixing device in the positioning and fixing device of the electromagnet provided by this utility model, and is not intended to limit the protection scope of this utility model. Other designs can be adaptively adjusted in position and number according to different vehicle models or different braking system devices, and similar design schemes should be included within the protection scope of this utility model.

[0076] Meanwhile, the positioning and fixing device for the electromagnet provided by this utility model achieves electrical connection between the electromagnet's electrical interface and the controller circuit board through an L-shaped electric needle. This facilitates more automated mechanical operation during assembly. Compared to the existing technology that uses conductive wires, the electrical connection formed in this utility model is more stable and robust, improving the positioning accuracy of the electromagnet and the reliability of the braking system. Furthermore, all components of the positioning and fixing device provided by this utility model are suitable for automated mechanical production lines, reducing the cost and quality error issues of manual assembly and improving assembly efficiency.
