Compared to a single throttle, a dual throttle configuration offers better intake uniformity, simpler software control strategies, and lower costs. However, for designs using a dual throttle configuration, the throttle and intake manifold are typically not directly connected to ensure optimal design. Instead, an intermediate structure is required to connect the two throttles to the manifold. However, this design suffers from poor stability, and because the intake manifold is made of plastic, it can be damaged by high-frequency engine vibrations.

[0003] Therefore, the prior art has the problem that the dual throttle valves of the intake system have poor stability. Utility Model Content

[0029] This specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," all of which may refer to one or more of the same or different embodiments according to the present invention.

[0030] In order to solve the problem of poor stability of dual throttle valves in the intake system in the prior art, the present application provides a dual throttle valve device and a vehicle.

[0031] Furthermore, the vehicle in the present application has the following dual throttle valve device.

[0032] like Figure 1 As shown, the dual throttle device of the present application includes a tee 10, two throttle valves 30, at least one fixing assembly 40, and at least one shock absorber assembly 50. One end of the tee 10 is connected to the manifold 20; the other two ends of the tee 10 are respectively connected to different throttle valves 30. The tee 10 is connected to the vehicle body 60 via the fixing assembly 40; the shock absorber assembly 50 is provided at the end where the fixing assembly 40 connects to the tee 10.

[0033] When using the dual throttle valve device of the present application, the manifold 20 can communicate with the two throttle valves 30 via the tee pipe 10 because of the tee pipe 10. Furthermore, because the dual throttle valve device of the present application also includes a fixing assembly 40 and a shock-absorbing assembly 50, after the tee pipe 10 is connected to the vehicle body 60 via the fixing assembly 40, the shock-absorbing assembly 50 can provide a shock-absorbing effect on the tee pipe 10, thereby preventing damage to the manifold 20 caused by the relative movement between the engine and the vehicle body 60, thereby protecting the manifold 20. Therefore, the dual throttle valve device of the present application effectively solves the problem of poor stability of dual throttle valves in intake systems in the prior art.

[0034] In a specific embodiment of the present application, Figure 1As shown, there are two fixing assemblies 40, and the fixing assemblies 40 are arranged at the end of the tee 10 connected to the throttle valve 30. Preferably, a fixing assembly 40 is provided at each end of the tee 10 connected to the two throttle valves 30, and the two fixing assemblies 40 are symmetrically arranged relative to the end of the tee 10 connected to the manifold 20. This arrangement can effectively ensure that the force between the fixing member 42 and the tee 10 is more stable. At the same time, this arrangement can also effectively ensure that the tee 10 will not be deflected under the weight of the two throttle valves 30. Preferably, in this application, the tee 10 includes a main line and two auxiliary lines respectively connected to the main line, and the two auxiliary lines are symmetrically arranged with respect to the main line. In addition, the main line is connected to the manifold 20, while the two auxiliary lines are respectively connected to different throttle valves 30. At the same time, a fixing assembly 40 is provided at the end of the two auxiliary lines away from the main line.

[0035] Of course, in the present application, the specific number of fixing components 40 can also be adjusted according to different usage scenarios.

[0036] Specifically, if Figure 1 As shown, the fixing assembly 40 includes a fixing bracket 41 and at least two fixing members 42. The two ends of the fixing bracket 41 are connected to the tee pipe 10 and the vehicle body 60 respectively through different fixing members 42, and the fixing bracket 41 is provided with fixing holes corresponding to the fixing members 42. In a specific embodiment of the present application, one end of the fixing bracket 41 is connected to the tee pipe 10 through a fixing member 42, and the other end of the fixing bracket 41 is connected to the vehicle body 60 through two fixing members 42. Of course, the specific number of fixing members 42 used can be adjusted according to actual conditions. Moreover, in the present application, the fixing members 42 can be bolts.

[0037] In a specific embodiment of the present application, the bolts used to connect the fixing bracket 41 to the vehicle body 60 are M8*16 hexagonal flange bolts, while the bolts used to connect the fixing bracket 41 to the tee pipe 10 are M10*25 hexagonal flange bolts. Therefore, the fixing bracket 41 is provided with fixing holes of different sizes.

[0038] Specifically, a blind mounting hole is provided on the outer surface of the tee pipe 10 corresponding to the fixing member 42. One end of the fixing member 42 corresponding to the tee pipe 10 passes through the fixing hole of the fixing bracket 41 and extends into the blind mounting hole. This arrangement effectively ensures the airtightness of the tee pipe 10, thereby preventing air leakage through the connection between the tee pipe 10 and the fixing member 42.

[0039] Preferably, if Figure 1As shown, the outer surface of the tee pipe 10 has at least one mounting protrusion 11, and each mounting protrusion 11 is respectively provided with at least one mounting blind hole. This arrangement makes it easier to assemble the fixing member 42 and the tee pipe 10, thereby improving the work efficiency of the operator.

[0040] Further preferably, the number of the mounting protrusions 11 is the same as the number of the fixing members 42 corresponding to the tee pipes 10 and they correspond one to one, and each mounting protrusion 11 is provided with a mounting blind hole.

[0041] Specifically, the shock-absorbing assembly is disposed at the end of the fixing bracket where it connects to the tee. The number of shock-absorbing assemblies 50 is the same as the number of fixing members 42 corresponding to the tee 10, and they correspond one-to-one. Furthermore, at least a portion of the shock-absorbing assembly 50 is disposed on the inner periphery of the fixing hole. In other words, in this application, a shock-absorbing assembly 50 is disposed on each fixing hole on the fixing bracket 41 that connects the tee 10 to the fixing member 42, thereby ensuring that the fixing member 42 and the shock-absorbing assembly 50 cooperate to provide a better fixation effect for the tee 10.

[0042] In a specific embodiment of the present application, Figure 2 As shown, the shock-absorbing assembly 50 includes a shock-absorbing sleeve 51 and an inner core 52. The shock-absorbing sleeve 51 is annular, and the outer periphery of the shock-absorbing sleeve 51 has a concave groove 511, and the shock-absorbing sleeve 51 is clamped with the inner periphery of the fixing hole through the concave groove 511; the fixing member 42 passes through the inner core 52 and is connected to the tee pipe 10, at least a portion of the inner core 52 is arranged inside the shock-absorbing sleeve 51, and the two ends of the inner core 52 respectively extend out of the shock-absorbing sleeve 51, and the end of the inner core 52 close to the tee pipe 10 has an abutting flange 521, and the abutting flange 521 abuts against the end face of the shock-absorbing sleeve 51. That is to say, in the present application, the shock-absorbing sleeve 51 is sleeved on the outside of the inner core 52. And in this embodiment, the shock-absorbing sleeve 51 is made of rubber material, so that the shock-absorbing assembly 50 can achieve a better shock-absorbing effect through the shock-absorbing sleeve 51.

[0043] Preferably, the shock-absorbing assembly 50 further includes a gasket 53, which is disposed over the end of the inner core 52 away from the abutment flange 521 and connected to the shock-absorbing sleeve 51. The provision of the gasket 53 not only effectively enhances the stability between the fixing bracket 41, the shock-absorbing assembly 50, and the fixing member 42, but also protects the shock-absorbing sleeve 51 and the inner core 52, thereby extending the service life of the shock-absorbing assembly 50 and ensuring the performance of the dual throttle device. Furthermore, the provision of the gasket 53 effectively prevents the shock-absorbing sleeve 51 from falling off.

[0044] Optionally, the control unit 31 of one of the two throttle valves 30 is located above the tee 10, while the control unit 31 of the other throttle valve 30 is located below the tee 10. Alternatively, the two throttle valves 30 are symmetrically arranged about the center of the tee 10. This arrangement allows two identical throttle valves 30 to be connected to the tee 10. In this application, ample space is reserved at the throttle valves 30 to facilitate the design of the air filter line.

[0046] 1. Effectively solve the problem of poor stability of the dual throttle valves in the intake system in the prior art;

[0047] 2. Simple structure and stable performance.
