Description

Technical Field

[0001] The utility model relates to the technical field of automotive throttle, in particular to an electronically controlled throttle body structure. Background Art

[0002] In the field of fuel vehicle modification, in order to improve fuel utilization rate, electronically controlled throttle bodies have been introduced on the market to accurately control fuel injection volume, butterfly valve opening degree, etc. However, the fuel injection volume is also affected by the fuel supply pressure. In order to more accurately control the fuel injection volume, it is also necessary to monitor the fuel supply line pressure so as to adjust the fuel injection volume according to the fuel supply pressure. However, due to the very limited space inside the throttle body, it is difficult to install the oil pressure sensor and do a good job in wiring during assembly. When each component is installed, it is easy to press the wire and cause a short circuit risk. Therefore, the existing sensors for monitoring the fuel supply line pressure are all installed on the external oil line. At this time, it is necessary to additionally modify the external oil line. Usually, an oil pressure sensor is installed on the external oil line through a tee, and an oil pressure gauge is set to display the real-time pressure. This method not only makes the modification operation inconvenient, but also cannot adjust the size of the fuel injection volume in real time when the fuel supply line pressure fluctuates. Therefore, it is necessary to make improvements. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an electronically controlled throttle body structure that is convenient to install and can adjust the fuel injection volume in real time.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] An electronically controlled throttle body structure includes a substantially rectangular body. The body has a number of air flow channels arranged in parallel and penetrating up and down. A butterfly valve for controlling the air volume, an atomization ring for atomizing fuel and entering the air flow channels, and a number of nozzles penetrating through one or both sides of the left and right of the body and corresponding to and communicating with each atomization ring are provided in the air flow channels. A first end cover forming a first cavity is fixedly fitted to one side of the left and right of the body. The inner wall of the first end cover is formed with a first oil path for supplying oil to the nozzles. A first interface protrudes from the side wall of the body opposite to the first end cover, and a second interface protrudes from the inner wall of the first end cover towards the body side. The second interface communicates with the first oil path. A tubular connector communicating with the second interface is inserted and fitted between the first interface and the second interface, and an oil pressure sensor is vertically and communicatively installed on the connector.

[0006] In a preferred solution, a panel forming a second cavity is also fixedly fitted to the front side of the body. A circuit board is installed in the second cavity. A through hole is provided between the first cavity and the second cavity. The wires of the nozzles and the oil pressure sensor pass through the through hole and are electrically connected to the circuit board.

[0007] In a preferred embodiment, two sets of the nozzles are inserted through one side of the body corresponding to the oil pressure sensor, and the two sets of nozzles are located at a position below the first cavity. The connecting member is located above the nozzles in the first cavity, and the oil pressure sensor is horizontally installed in the first cavity with its tail end corresponding to the through hole.

[0008] In a preferred embodiment, the first oil passage is horizontally arranged on the inner wall of the first end cover. The second interface is arranged on one side above the first oil passage and corresponds to the position of the first interface. On the lower side of the first oil passage, first insertion interfaces respectively inserted and matched with the two sets of nozzles extend out, and the two sets of first insertion interfaces are both communicated with the first oil passage.

[0009] In a preferred embodiment, a second end cover forming a third cavity is fixedly coupled to the other side of the body opposite to the first end cover. A second oil passage is horizontally arranged on the inner wall of the second end cover. Two sets of the nozzles are inserted through one side of the body corresponding to the second end cover. On the lower side of the second oil passage, second insertion interfaces respectively inserted and matched with the two sets of nozzles on this side extend out, and the two sets of second insertion interfaces are both communicated with the second oil passage.

[0010] In a preferred embodiment, a third oil passage communicating the first oil passage and the second oil passage is integrally formed on the rear side wall of the body.

[0011] The beneficial effects of the present utility model are as follows: During installation, first install the oil pressure sensor on the connecting member, and then insert and fix one end of the connecting member into the first interface of the body. When the first end cover is closed with the body, the other end of the connecting member just completes the insertion and matching with the second interface. Therefore, it is possible to avoid installing the sensor and wiring in a narrow space and avoid pressing the wires by each component, which greatly facilitates the installation of the oil pressure sensor and solves the problem of wire pressing. Compared with the prior art, integrating the oil pressure sensor on the throttle body can achieve linkage with the control of the nozzles and the butterfly valve to realize real-time control of the fuel injection volume when the oil pressure fluctuates, making the control more accurate.

[0019] The present utility model will be further described below with reference to the accompanying drawings:

[0020] Referring to Figures 1 to 6 As shown, an electronically controlled throttle body structure includes a substantially rectangular body 1. The body 1 is provided with a plurality of air flow channels 11 arranged in parallel and penetrating up and down. A butterfly valve 12 for controlling the air volume, an atomizing ring 13 for atomizing fuel and entering the air flow channels 11, and a plurality of nozzles 14 penetrating through one or both sides of the left and right sides of the body 1 and corresponding to and communicating with each atomizing ring 13 are arranged in the air flow channels 11. A first end cap 2 forming a first cavity is fixedly fitted to one side of the left and right sides of the body 1. A first oil passage 21 for supplying oil to the nozzles 14 is formed on the inner wall of the first end cap 2. A first interface 15 protrudes from the side wall of the body 1 opposite to the first end cap 2, and a second interface 22 protrudes from the inner wall of the first end cap 2 toward the body 1. The second interface 22 communicates with the first oil passage 21. A tubular connecting piece 3 communicating with the second interface 22 is inserted and fitted between the first interface 15 and the second interface 22, and an oil pressure sensor 31 is vertically and communicatively installed on the connecting piece 3.

[0021] During installation, first install the oil pressure sensor 31 on the connecting piece 3, and then insert and fix one end of the connecting piece 3 to the first interface 15 of the body 1. When the first end cap 2 is covered with the body 1, the other end of the connecting piece 3 just completes the insertion and fitting with the second interface 22. Therefore, it is possible to avoid installing the oil pressure sensor and wiring in a narrow space, and avoid pressing the wires by each component, which greatly facilitates the installation of the oil pressure sensor 31 and solves the problem of wire pressing. Compared with the prior art, integrating the oil pressure sensor 31 on the throttle body can realize linkage control with the nozzles 14 and the butterfly valve 12 to realize real-time control of the fuel injection volume when the oil pressure fluctuates, making the control more accurate.

[0022] In a preferred solution, a panel 4 forming a second cavity is fixedly fitted to the front side of the body 1 of this embodiment. A circuit board 41 is installed in the second cavity. A via hole 16 is provided between the first cavity and the second cavity. The wires of the nozzle 14 and the oil pressure sensor 31 both pass through the via hole 16 and are electrically connected to the circuit board 41. Connecting the wires of each part to the circuit board 41 and then making an external electrical connection can prevent short circuits caused by scattered wiring of each wire.

[0023] In a preferred solution, two groups of the nozzles 14 are provided on one side of the body 1 of this embodiment corresponding to the oil pressure sensor 31 in a penetrating manner. The two groups of the nozzles 14 are located at a position below the first cavity, while the connector 3 is located above the nozzles 14 in the first cavity. The oil pressure sensor 31 is horizontally installed in the first cavity and its tail end corresponds to the via hole 16. Since the oil pressure sensor 31 is horizontally arranged in the upper part of the first cavity, it can be seen as a whole by the installer during the installation process, making the installation convenient. And its tail end corresponds to the via hole 16, making the length of the wire remaining in the first cavity very short, avoiding being pressed by other components and causing short circuits.

[0024] In a preferred solution, the first oil passage 21 of this embodiment is horizontally arranged on the inner wall of the first end cap 2. The second interface 22 is arranged on the upper side of the first oil passage 21 and corresponds to the position of the first interface 15. The lower side of the first oil passage 21 extends out to form first insertion interfaces 23 respectively plugged and matched with the two groups of the nozzles 14, and the two groups of the first insertion interfaces 23 are both communicated with the first oil passage 21. During assembly, only by covering the first end cap 2 on the body 1 can the connector 3 be plugged and matched with the second interface 22, and the first insertion interfaces 23 be plugged and matched with the nozzles 14, making the assembly convenient and fast.

[0025] In a preferred solution, a second end cap 5 forming a third cavity is fixedly fitted to the other side of the body 1 of this embodiment opposite to the first end cap 2. A second oil passage 51 is horizontally arranged on the inner wall of the second end cap 5. Two groups of the nozzles 14 are provided on one side of the body 1 corresponding to the second end cap 5 in a penetrating manner. The lower side of the second oil passage 51 extends out to form second insertion interfaces 52 respectively plugged and matched with the two groups of the nozzles 14 on this side, and the two groups of the second insertion interfaces 52 are both communicated with the second oil passage 51. Similarly, during assembly, only by covering the second end cap 5 on the body 1 can the second insertion interfaces 52 be plugged and matched with the nozzles 14, making the assembly convenient and fast.

[0026] In a preferred solution, a third oil passage 17 communicating the first oil passage 21 and the second oil passage 51 is integrally formed on the rear side wall of the body 1 in this embodiment. The oil passages are arranged on the first end cover 2, the rear side of the body 1 and the second end cover 5, with high integration degree, which can save the installation space and has stronger integrity, making the structure more stable.

[0027] The above is not intended to limit the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solutions of the present invention.
