Description

Technical Field

[0001] The utility model relates to the technical field of automotive commutators, and particularly relates to an automotive commutator with high temperature resistance. Background Technique

[0002] In a motor starter for an automobile, a commutator is an essential and important component. Its stability and reliability are crucial for affecting the performance of the motor starter. Currently, when producing a commutator, commutator segments are directly welded onto a sleeve. The existing welding method of this commutator has a single structure. After long-term use, when the commutator segments are severely worn, the entire commutator needs to be replaced, wasting other intact components of the commutator, and thus its practicality is relatively low.

[0003] After retrieval, the patent with the patent publication number CN202221595058.1 discloses an improved automotive commutator structure. Although when this device is in use, by screwing bolts, two discs can be respectively fixed at both ends of a cylinder body. At this time, the fixation of the discs can limit the movement of concave strips, thereby achieving the fixation of the commutator segments. However, when this device is in use, the discs at both ends of the cylinder body need to be respectively installed and disassembled. Since the discs at both ends of the cylinder body need to be respectively installed and disassembled, this process is relatively complex and time-consuming. When repairing or replacing the commutator segments, additional operation steps are required, increasing the maintenance cost and workload. Moreover, the conductive strips and the coils are rigidly connected, generating noise or loosening due to vibration during vehicle operation, affecting the stability and service life of the commutator. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides an automotive commutator with high temperature resistance, and solves the problems put forward in the background technique.

[0005] The solution of the utility model to the above technical problems is as follows:

[0006] An automotive commutator with high temperature resistance includes a base. Commutator segments are installed on the outer side of the base. A base is installed at the bottom end of the base through bolts. The commutator segments are clamped and fixed on the base through the base.

[0007] A reed is arranged at the upper end of the commutator segment. A limiting seat is arranged at the bottom end of the commutator segment. A second through hole is penetrated through the limiting seat. A third positioning groove is opened on the base. A first through hole and a third convex block are arranged on the base at the position of the third positioning groove. The base limits the installation position of the commutator segment through the third positioning groove, and the third convex block is inserted into the second through hole on the limiting seat to further position the commutator segment.

[0008] A connection hole is provided at the bottom end of the base, and the bolt passes through the first through hole and the second through hole and is threadedly connected to the connection hole. Thus, the base and the base cooperate with each other through the bolt to clamp and fix the commutator segment.

[0009] Based on the above technical solutions, the present utility model can also be improved as follows.

[0010] Further, a first positioning groove is provided on the commutator segment, and a first convex block is provided below the commutator segment at the first positioning groove.

[0011] The beneficial effects of adopting the above further solution are:

[0012] The cooperative design of the first positioning groove and the first convex block realizes the precise positioning and fixation between the commutator segment and the base or other components. This design reduces the error in the installation process and improves the overall accuracy and stability of the commutator. By providing a convex block on the commutator segment and inserting it into the corresponding structure (such as the second positioning groove) on the base, the connection strength between the commutator segment and the base can be enhanced. This strengthening of the structure helps to resist the vibration and impact generated during the operation of the motor and improves the durability and reliability of the commutator. This design enables the commutator segment to be disassembled and replaced more conveniently when needed. During maintenance, only by loosening the corresponding fixing parts, the commutator segment can be removed from the base without large-scale disassembly of the entire commutator. This not only saves maintenance time but also reduces maintenance costs.

[0013] Further, a second convex block is provided on the base, and a second positioning groove is provided below the second convex block on the base.

[0014] The beneficial effects of adopting the above further solution are:

[0015] The mutual cooperation of the second convex block and the second positioning groove provides a more stable support for the components on the base. This design enhances the overall structural stability of the base, enabling it to resist external vibration and impact, thereby improving the durability and reliability of the equipment. By precisely designing the dimensions and positions of the second convex block and the second positioning groove, the accurate installation of other components (such as the commutator, sensors, etc.) on the base can be ensured. This design reduces the error in the installation process and improves the overall accuracy of the equipment. When it is necessary to repair or replace the components on the base, the design of the second convex block and the second positioning groove makes the disassembly and assembly process more convenient. The operator can quickly locate and disassemble the components, thus saving repair time and costs.

[0016] Further, the base and the commutator segment are spliced and limited by inserting the second convex block into the first positioning groove and the first convex block into the second positioning groove.

[0017] The beneficial effects of adopting the above further solution are:

[0018] The insertion design of the second bump with the first positioning groove and the first bump with the second positioning groove realizes the precise positioning between the base and the commutator segment. This design reduces the error during the installation process, ensuring the accuracy and stability of the connection. Through the way of limit splicing, the position of the commutator segment on the base is further fixed and restricted. This prevents the loosening or displacement of the commutator segment during the operation of the motor, improving the overall stability and reliability. The dual insertion design of the second bump with the first positioning groove and the first bump with the second positioning groove provides double fixation for the connection between the base and the commutator segment. This design enhances the strength of the connection point, making the connection more firm. During the operation of the motor, the commutator segment is subjected to various forces. Through the dual insertion design, these forces can be dispersed to a wider area, reducing local stress concentration and improving the overall strength of the structure. Due to the adoption of the insertion and limit splicing design, the disassembly and assembly process between the base and the commutator segment becomes simple and fast. When it is necessary to repair or replace the commutator segment, the operator can quickly complete the disassembly and assembly work, improving the maintenance efficiency. The fast disassembly and assembly design reduces the maintenance cost. The operator does not need to use complex tools or perform cumbersome operations to complete the maintenance work, reducing the additional cost brought by maintenance.

[0019] Further, the commutator segments are distributed in a circular array on the outer side of the base.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The commutator segments are distributed in a circular array on the outer side of the base, making the structure of the entire commutator more compact. This layout effectively utilizes the space on the outer side of the base, reducing unnecessary space waste. The circular array layout also helps to optimize the layout of other components inside the commutator, making the structure of the entire commutator more reasonable and compact. The circular array distribution of the commutator segments helps to achieve uniform heat dissipation. During the operation of the motor, the commutator segments generate a certain amount of heat, and the circular array layout can make the heat more evenly distributed on the outer side of the base, which is beneficial to the rapid dissipation of heat.

[0022] Further, the third positioning grooves are evenly distributed on the base, and the first through holes and the third bumps are cross-distributed on the third positioning grooves.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] The uniform distribution of the third positioning grooves on the base enables the base to maintain a stable posture when bearing various forces and moments. This design of uniform distribution helps to reduce the risk of deformation or damage to the base caused by uneven stress, thereby improving the stability of the entire structure. The cross-distribution of the first through holes and the third bumps on the third positioning grooves achieves precise positioning between components. This design reduces errors during the installation process, ensures accurate connection and fitting between components, and improves the accuracy of the entire structure.

[0025] The utility model provides a high-temperature-resistant automotive commutator, which has the following beneficial effects:

[0026] Through the multiple plug-in and limit splicing design between the base, the commutator segments, and the base, the structure of the entire commutator is very stable, capable of withstanding mechanical stress and thermal stress in a high-temperature environment, ensuring the reliability and durability of the commutator under high-temperature conditions.

[0027] By utilizing the mutual cooperation of the first positioning groove, the second positioning groove, the third positioning groove, as well as the bumps and through holes, precise positioning and installation between the commutator segments and the base are achieved. This design not only simplifies the installation process but also improves the installation accuracy, ensuring the stability and performance of the commutator during operation.

[0028] Due to the adoption of a modular design, such as the detachable connection between the commutator segments and the base, it is more convenient to operate when maintenance or component replacement is required, reducing the maintenance cost and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 4 as shown, the embodiments provided by the present invention are as follows:

[0039] Embodiment 1: A high-temperature resistant automotive commutator, including a base 1, with commutator segments 2 installed on the outer side of the base 1. The commutator segments 2 are distributed in a circular array on the outer side of the base 1. The circular array layout of the commutator segments 2 on the outer side of the base 1 realizes the compact design of the commutator structure. This layout strategy makes full use of the space outside the base 1, effectively avoiding the waste of space resources. The circular array layout also helps to optimize the arrangement of the internal components of the commutator, improving the rationality and compactness of the overall structure. In addition, this layout helps to evenly distribute and quickly dissipate heat, reducing the risk of heat accumulation generated by the commutator segments 2 during the operation of the motor, improving the thermal management performance of the commutator. A first positioning groove 204 is provided on the commutator segment 2, and a first protrusion 205 is provided below the commutator segment 2 at the position of the first positioning groove 204. The precise cooperation design of the first positioning groove 204 and the first protrusion 205 realizes the high-precision positioning and stable fixation between the commutator segment 2 and the base 1 or related components. This design strategy significantly reduces the assembly error, thereby improving the overall precision and operating stability of the commutator. By integrating protrusions on the commutator segment 2 and implementing plug-in coupling with corresponding structures such as the second positioning groove 103 on the base 1, the connection rigidity between the commutator segment 2 and the base 1 is effectively enhanced. This structural strengthening measure effectively resists the vibration and impact generated during the operation of the motor, significantly improving the durability and operating reliability of the commutator. In addition, this design also endows the commutator segment 2 with convenient disassembly and replacement characteristics. During maintenance, only by releasing the corresponding fasteners, the commutator segment 2 can be easily separated from the base 1 without complex disassembly of the entire commutator, thus greatly shortening the maintenance cycle and reducing the maintenance cost. The bottom end of the base 1 is installed with a base 3 through bolts 4. The base 1 is provided with a second protrusion 101, and a second positioning groove 103 is provided below the second protrusion 101 on the base 1. The synergistic effect of the second protrusion 101 and the second positioning groove 103 constructs a more solid support system for the components carried by the base 1. This design significantly enhances the overall structural rigidity of the base 1, effectively resisting external vibration and impact, and thus improving the durability and operating reliability of the equipment. By finely adjusting the size and position parameters of the second protrusion 101 and the second positioning groove 103, the precise installation of various components (such as commutators, sensors, etc.) on the base 1 is ensured, significantly reducing the assembly error and improving the overall precision of the equipment. During the maintenance or replacement of the components of the base 1, this design simplifies the disassembly and assembly process, enabling the operator to quickly locate and disassemble the required components, effectively shortening the repair cycle and reducing the cost. The base 1 and the commutator segment 2 are spliced by inserting and connecting the second protrusion 101 with the first positioning groove 204 and the first protrusion 205 with the second positioning groove 103 for limit. The plug-in coupling design of the second protrusion 101 with the first positioning groove 204 and the first protrusion 205 with the second positioning groove 103 realizes the high-precision positioning between the base 1 and the commutator segment 2. This design strategy effectively reduces the error accumulation during the assembly process, ensuring the precise matching and stability of the connection interface.The position of the commutator segment 2 on the base 1 is further locked by the limited splicing mechanism, which effectively prevents loosening or displacement during the operation of the motor and improves the stability and reliability of the overall structure. The double plug-in design not only enhances the strength of the connection point, but also reduces local stress concentration by dispersing the stress area, thereby improving the overall bearing capacity of the structure. At the same time, the design also simplifies the disassembly and assembly process between the base 1 and the commutator segment 2, improves maintenance efficiency and reduces maintenance costs. The commutator segment 2 is clamped and fixed on the base 1 by the base 3.

[0040] Embodiment 2: In order to facilitate the definition of the installation position of the commutator segment 2, for example, Figures 1 to 4 As shown, the present invention also includes: a spring sheet 201 is provided at the upper end of the commutator segment 2, a limit seat 202 is provided at the bottom end of the commutator segment 2, a second through hole 203 is provided through the limit seat 202, a third positioning groove 303 is provided on the base 3, and a first through hole 301 and a third protrusion 302 are provided at the third positioning groove 303 of the base 3, the third positioning groove 303 is evenly distributed on the base 3, and the first through hole 301 and the third protrusion 302 are cross-distributed on the third positioning groove 303, and the uniform distribution design of the third positioning groove 303 on the base 3 ensures that the base 3 can maintain a stable structural form when subjected to complex loads. This design effectively reduces the risk of deformation or damage of the base 3 due to uneven force, and improves the stability of the overall structure. The cross layout of the first through hole 301 and the third protrusion 302 on the third positioning groove 303 realizes high-precision positioning and assembly between components. This design strategy significantly reduces assembly errors, ensures precise fit and connection strength between components, and improves the accuracy and reliability of the entire structure. The base 3 limits the installation position of the commutator segment 2 through the third positioning groove 303, and the third protrusion 302 and the second through hole 203 on the limit seat 202 are plugged into each other to further position the commutator segment 2.

[0041] Embodiment 3: In order to facilitate the clamping and fixing of the commutator segment 2, for example, Figures 1 to 4 As shown, the present invention also includes: a connecting hole 102 is opened at the bottom end of the base 1, and the bolt 4 passes through the first through hole 301 and the second through hole 203 and is threadedly connected to the connecting hole 102, and then the base 3 and the base 1 cooperate with each other through the bolt 4 to clamp and fix the commutator segment 2.

[0042] Working principle:

[0043] The commutator adopts a modular design, and the commutator segments and the base can be easily disassembled and installed. This design enables the problematic part to be individually removed when maintenance or component replacement is required, without the need to replace the entire commutator, greatly improving the convenience and efficiency of maintenance. Through the mutual cooperation of the first positioning groove, the second positioning groove, the third positioning groove, the convex block and the through hole, the precise positioning and fixation between the commutator segments and the base are achieved. This design not only ensures the installation accuracy, but also makes the disassembly and assembly process simpler and faster. The base and the base are tightly connected by bolts. During disassembly and assembly, only by loosening or tightening the bolts can the separation or fixation of the components be realized. This fastening method is simple and reliable, and easy to operate.

[0044] As one of the key components in the commutator, the main function of the reed is to provide elastic connection and conductive function. During the rotation of the motor, the reed can maintain good contact with the commutator segments, ensuring the continuous transmission of current and the smooth progress of commutation. The reed has a certain elastic deformation ability and can adapt to the vibration and displacement generated during the rotation of the motor. This adaptability enables the reed to always maintain close contact with the commutator segments, thus ensuring the stable transmission of current and the accuracy of commutation.

[0045] The above has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
