Description

Technical Field

[0001] This utility model relates to the technical field of automobile engine intake systems, and in particular to a throttle valve. Background Technology

[0002] The throttle body is an important component of a car engine. For example, the electronic throttle body uses an electronic throttle control system, which helps to improve the smoothness and economy of the car's driving and can effectively reduce emissions. At the same time, the system responds quickly and can achieve satisfactory handling performance.

[0003] In existing technologies, the throttle valve often has a spring seat (e.g.) Figure 7 and Figure 8 The upper spring seat 20 and the lower spring seat 22 are shown in the figure. The return spring 21 is fitted on the spring seat (which is spliced ​​together from the upper spring seat 20 and the lower spring seat 22). The return gear 23 is connected to the upper spring seat 20 to form a return gear assembly. The number of parts is large and the installation is complicated, which is not conducive to production and manufacturing.

[0004] Therefore, how to make the installation of the reset gear assembly easier has become a technical problem that needs to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a throttle valve, which mainly solves the problem of how to make the installation of the reset gear assembly easier in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a throttle valve, characterized in that: the throttle valve includes a reset gear, a reset gear sleeve, and a reset gear baffle, wherein the reset gear, reset gear sleeve, and reset gear baffle are injection molded as a single unit.

[0007] Furthermore, the throttle valve also includes a return spring, which is mounted on the return gear sleeve.

[0008] Furthermore, the reset gear is provided with a reset gear support foot, and the two sides of the reset gear support foot are the first side side and the second side side of the reset gear support foot, respectively. The first side side and the second side side of the reset gear support foot have the same shape and are arranged symmetrically.

[0009] Furthermore, the throttle body also includes a DC motor and a valve body. The DC motor is installed in the valve body and is connected to the valve body by DC motor screws.

[0010] Furthermore, a valve body stop is provided inside the valve body;

[0011] The return spring includes a first torsion arm and a second torsion arm. When the throttle plate is in the emergency position, the first torsion arm simultaneously contacts the first side of the return gear support and one side of the valve body block, and the second torsion arm simultaneously contacts the second side of the return gear support and the other side of the valve body block.

[0012] Furthermore, the throttle body also includes a throttle shaft and a throttle plate. The throttle shaft is connected to the reset gear by welding, and the throttle plate is connected to the throttle shaft by throttle plate screws.

[0013] In view of the above technical features, the present invention has the following beneficial effects:

[0014] 1. This utility model discloses a throttle body by injection molding the reset gear, reset gear sleeve, and reset gear baffle into a single unit. Installation of the reset gear assembly is completed simply by fitting the reset spring onto the reset gear sleeve. Because the reset gear, reset gear sleeve, and reset gear baffle are injection molded as a single unit, there is no need for a separate connection operation between the reset gear and the reset gear sleeve. The reset gear sleeve performs the function and role of the existing spring seat, making the installation of the reset gear assembly simpler, reducing the number of parts, and facilitating throttle body manufacturing. Furthermore, eliminating the need for a separate connection operation between the reset gear sleeve and the reset gear baffle further reduces the number of parts, further facilitating throttle body manufacturing and improving the ease of installation of the reset gear assembly.

[0025] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0026] See Figures 1 to 6 In specific embodiment 1, this embodiment 1 provides a throttle valve, including a reset gear 1, a reset gear sleeve 3 and a reset gear baffle 7, which are injection molded as a single unit.

[0027] The throttle valve also includes a return spring 9, which is mounted on the return gear sleeve 3.

[0028] The reset gear 1 is provided with a reset gear support 10. The two sides of the reset gear support 10 are the first side 11 and the second side 12 of the reset gear support, respectively. The first side 11 and the second side 12 of the reset gear support have the same shape and are arranged symmetrically.

[0029] The throttle valve also includes a DC motor 15 and a valve body 13. The DC motor 15 is installed in the valve body 13 and is connected to the valve body 13 by a DC motor screw 14.

[0030] A valve body stop 16 is provided inside the valve body 13.

[0031] The return spring 9 includes a first torsion arm 8 and a second torsion arm 2. When the throttle plate 4 is in the emergency position, the first torsion arm 8 simultaneously contacts the first side 11 of the return gear support and one side of the valve body block 16, and the second torsion arm 2 simultaneously contacts the second side 12 of the return gear support and the other side of the valve body block 16.

[0032] The throttle body also includes a throttle shaft 6 and a throttle plate 4. The throttle shaft 6 is connected to the reset gear 1 by welding, and the throttle plate 4 is connected to the throttle shaft 6 by a throttle plate screw 5.

[0033] In this embodiment 1, when the throttle valve is in use, the DC motor 15 drives the reset gear 1 to rotate, which in turn drives the throttle shaft 6 to rotate. The throttle shaft 6 then drives the throttle plate 4 to rotate, thereby adjusting the intake air volume of the throttle body through the rotation of the throttle plate 4.

[0034] In this embodiment 1, the throttle body is injection molded as a single unit, comprising the reset gear 1, the reset gear sleeve 3, and the reset gear baffle 7. Installation of the reset gear assembly is completed simply by fitting the reset spring 9 onto the reset gear sleeve 3. Since the reset gear 1, reset gear sleeve 3, and reset gear baffle 7 are injection molded as a single unit, there is no need for a separate connection operation between the reset gear 1 and the reset gear sleeve 3. The reset gear sleeve 3 performs the function and role of the existing spring seat, making the installation of the reset gear assembly simpler, reducing the number of parts, and facilitating throttle body manufacturing. Furthermore, the elimination of the need for a separate connection operation between the reset gear sleeve 3 and the reset gear baffle 7 further reduces the number of parts, further facilitating throttle body manufacturing and improving the ease of installation of the reset gear assembly.
