Description

Technical Field

[0001] The utility model belongs to the field of automobile starters, and in particular relates to a high-reliability automobile starter. Background Art

[0002] In modern automotive technology, the starter is a key component responsible for providing the necessary driving force during the engine startup phase, and its performance is directly related to the vehicle's start-stop efficiency and driving experience. The core transmission components of traditional automotive starters generally use a fork-type transmission mechanism. Although the fork-type design has been used for many years and has been widely used, its shortcomings have gradually become apparent with the advancement of technology and the continuous improvement of users' requirements for automotive performance.

[0003] The main problem with scotch fork transmissions is their relatively low reliability. Since scotch fork transmissions are mostly asymmetrical in layout, they are susceptible to wear and tear over long periods of operation, leading to loose connections, inaccurate engagement or failure. These factors are further exacerbated under high-frequency starting, extreme temperature changes or vibration conditions, affecting the success rate and stability of starting.

[0004] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the utility model provides a high-reliability automobile starter, which improves the reliability of the starter through a symmetrical double-switch design.

[0006] In order to solve the above technical problems, the utility model solves them through the following technical solutions.

[0007] A high-reliability automobile starter comprises an electric motor, a transmission member and an electromagnetic switch, wherein the electric motor has an output shaft, the output shaft is provided with a connecting groove section, the connecting groove section is sleeved with a starting sleeve, and the starting sleeve is provided with a connecting spline that cooperates with the connecting groove section. The starting sleeve is equipped with a starting gear and a one-way clutch, the transmission member connects the electromagnetic switch and the starting sleeve, and the electromagnetic switch controls the axial movement of the starting sleeve through the transmission member. There are two electromagnetic switches, and the two electromagnetic switches are symmetrically distributed about the motor. An assembly groove is provided on the starting sleeve, and the transmission member comprises a sleeve portion assembled and connected to the assembly groove and connecting portions located on both sides of the sleeve portion, and the connecting portions are connected to the electromagnetic switch.

[0008] Preferably, the present application further comprises a front shell, wherein the front shell is provided with an upwardly opening receiving groove for receiving the starter gear, and a plurality of channels are provided at the bottom of the receiving groove. The design of the channels can prevent impurities such as sludge and dust from accumulating at the bottom of the receiving groove. In this way, excessive accumulation of sludge is avoided to hinder the operation of the starter gear, so that the starter can maintain a good working condition for a longer period of time.

[0009] Preferably, the channel is distributed in an annular shape around the axis of the starting gear, and the width of the channel along the axial direction of the receiving groove is the same as the height of the inner wall of the receiving groove. This design is conducive to the sludge to escape from the receiving groove and can help the heat dissipation at the starting gear.

[0010] Preferably, the front shell has a cylinder wall, the end surface of the cylinder wall is equipped with an end cover, and the cylinder wall and the end cover cooperate to form a receiving groove. This design facilitates cleaning of the channel.

[0011] Preferably, the cross section of the channel is a curved S-shape. The curved structure of the S-shaped channel significantly increases the flow path length when air or substances pass through it. Compared with a straight channel, such a design can more effectively block the straight-line entry of external dust and impurities, forcing them to be deposited on the channel wall due to inertia at the bends instead of continuing to be transmitted forward, thereby greatly reducing the probability of dust entering the receiving slot.

[0012] Compared with the prior art, the present application has the following beneficial effects: this structural design enables the starter to respond more smoothly and quickly during starting, thereby improving starting efficiency and reliability. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Reference Figures 1 to 5 A high-reliability automobile starter comprises a motor 100, a transmission member 200 and an electromagnetic switch 300. The motor 100 has an output shaft 110, the output shaft 110 is provided with a connecting groove section, the connecting groove section is provided with a starting sleeve 120, and the starting sleeve 120 is provided with a connecting spline that cooperates with the connecting groove section. The starting sleeve 120 is equipped with a starting gear 130 and a one-way clutch 140, the transmission member 200 connects the electromagnetic switch 300 and the starting sleeve 120, and the electromagnetic switch 300 controls the axial movement of the starting sleeve 120 through the transmission member 200. There are two electromagnetic switches 300, and the two electromagnetic switches 300 are symmetrically distributed about the motor 100. The starting sleeve 120 is provided with an assembly groove, and the transmission member 200 comprises a sleeve portion 210 assembled and connected with the assembly groove and connecting portions 220 located on both sides of the sleeve portion 210, and the connecting portion 220 is connected to the electromagnetic switch 300.

[0027] The high-reliability automobile starter of the present application adopts a dual electromagnetic switch 300 design. The symmetrical distribution of the two electromagnetic switches 300 ensures the balance of axial driving force and reduces jamming. In the event of a failure of a single electromagnetic switch 300, the other electromagnetic switch 300 can still maintain the basic starting function, significantly enhancing the reliability and stability of the system operation.

[0028] Furthermore, the present application is equipped with a front shell 400 at the front end, and the front shell 400 is provided with an upwardly open receiving groove 410 for receiving the starting gear 130, and a plurality of channels 420 are provided at the bottom of the receiving groove 410. The design of the channel 420 can prevent impurities such as sludge and dust from accumulating at the bottom of the receiving groove 410. This avoids excessive accumulation of sludge and hindering the operation of the starting gear 130, so that the starter can maintain a good working condition for a longer time. The channel 420 is distributed in a ring around the axis of the starting gear 130, and the width of the channel 420 along the axial direction of the receiving groove 410 is the same as the height of the inner wall of the receiving groove 410. This design is conducive to the sludge to escape from the receiving groove 410, and can help the heat dissipation at the starting gear 130.

[0029] For the convenience of maintenance, the front shell 400 has a cylinder wall 430, and the end surface of the cylinder wall 430 is equipped with an end cover 440. The cylinder wall 430 and the end cover 440 cooperate to form a receiving groove 410. This design facilitates the cleaning of the channel 420. The cross section of the channel 420 is a curved S shape. The curved structure of the S-shaped channel 420 significantly increases the flow path length when air or substances pass through. Compared with the straight channel 420, such a design can more effectively hinder the straight-line entry of external dust and impurities, forcing them to be deposited on the wall of the channel 420 due to inertia at the bends instead of continuing to be transmitted forward, thereby greatly reducing the probability of dust entering the receiving groove 410.

Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
