DETAILED DESCRIPTION

[0029] The following is a specific embodiment of the utility model and in combination with the drawings, the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments.

[0030] As Figures 1 to 5 ​​As shown, an electronic accelerator pedal comprises: a pedal base 100; a pedal arm 200, the pedal arm 200 comprising a hinged part 210, the hinged part 210 being mounted to the pedal base 100; a pedal shaft assembly, the pedal shaft assembly comprising a shaft sleeve 300 and a rotating shaft 400, the shaft sleeve 300 being provided through the pedal base 100 and the hinged part 210, the shaft sleeve 300 being fixedly connected to the pedal base 100, the hinged part 210 being hinged to the pedal base 100 through the shaft sleeve 300, the rotating shaft 400 being rotatably provided through the shaft sleeve 300 and coaxially arranged with the shaft sleeve 300, the hinged part 210 being circumferentially fixedly connected to the rotating shaft 400.

[0031] The pedal base 100 is fixedly mounted on a vehicle body, serving as a support base of the entire accelerator pedal system. One end of the pedal arm 200 is provided as the hinged part 210. The pedal base 100 is provided with a notch structure, and the hinged part 210 is mounted in the notch structure of the pedal base 100. The other end of the pedal arm 200 is used for being stepped on by a driver. The shaft sleeve 300 is provided through the pedal base 100 and the hinged part 210, and the pedal base 100 and the hinged part 210 are hinged together through the shaft sleeve 300. That is, the main function of the shaft sleeve 300 is to support the rotation of the pedal arm 200 relative to the pedal base 100. The rotating shaft 400 is a component that can freely rotate in the shaft sleeve 300. The rotating shaft 400 is circumferentially fixedly connected to the hinged part 210. The rotating shaft 400 does not need to bear the function of the hinge shaft, but only needs to rotate in the shaft sleeve 300. When the driver steps on or releases the pedal arm 200, the rotating shaft 400 will rotate together with the hinged part 210.

[0032] The split design of the pedal shaft assembly allows the shaft sleeve 300 and the rotating shaft 400 to be installed as independent components, reducing the complexity of assembling multiple components at one time. Moreover, the split design is easier to manufacture.

[0033] In addition, it should be noted that the main purpose of providing the rotating shaft 400 is to mount the magnetic steel 420 at the end of the rotating shaft 400. When the rotating shaft 400 rotates, the magnetic steel 420 rotates. The position change of the magnetic steel 420 can accurately reflect the angle change of the pedal arm 200, so as to achieve the purpose of angle position detection.

[0034] The rotating shaft 400 is independently provided in the shaft sleeve 300. Since the end of the rotating shaft 400 can protrude out of the shaft sleeve 300, the magnetic steel 420 can be very close to the Hall sensor. This means that the magnetic field generated by the magnetic steel 420 is more concentrated on the Hall sensor, thereby enhancing the signal strength and improving the detection accuracy, while reducing the sensitivity to external magnetic field interference. Because the magnetic steel 420 is already close enough to the Hall sensor, a magnetic yoke does not need to be installed on the pedal shaft assembly to guide or enhance the magnetic field, thereby simplifying the design of the entire pedal shaft assembly.

[0035] As shown in FIG. 1, the pedal base 100 is fixedly mounted on a vehicle body, serving as a support base of the entire accelerator pedal system. One end of the pedal arm 200 is provided as the hinged part 210. The pedal base 100 is provided with a notch structure, and the hinged part 210 is mounted in the notch structure of the pedal base 100. The other end of the pedal arm 200 is used for being stepped on by a driver. The shaft sleeve 300 is provided through the pedal base 100 and the hinged part 210, and the pedal base 100 and the hinged part 210 are hinged together through the shaft sleeve 300. That is, the main function of the shaft sleeve 300 is to support the rotation of the pedal arm 200 relative to the pedal base 100. The rotating shaft 400 is a component that can freely rotate in the shaft sleeve 300. The rotating shaft 400 is circumferentially fixedly connected to the hinged part 210. The rotating shaft 400 does not need to bear the function of the hinge shaft, but only needs to rotate in the shaft sleeve 300. When the driver steps on or releases the pedal arm 200, the rotating shaft 400 will rotate together with the hinged part 210. Figures 1 to 3As shown, based on the above embodiment, the pedal seat 100 includes two side wall portions 110, each of which is provided with a support hole 111. The hinge portion 210 is provided with a hinge hole 211. The hinge portion 210 is installed between the two side wall portions 110. The hinge hole 211 is located between the two support holes 111. The hinge hole 211 and the two support holes 111 are coaxially arranged. The bushing 300 passes through the hinge hole 211 and the two support holes 111.

[0036] The pedal seat 100 includes two opposing sidewall portions 110, with a notch structure formed between them, allowing the hinge portion 210 to be installed within the notch structure. Each sidewall portion 110 has a support hole 111 for accommodating a bushing 300 and providing a precise installation position. The hinge portion 210 has a central hinge hole 211, which is coaxially aligned with the support hole 111 on the sidewall portion 110. The hinge hole 211 is designed to allow the bushing 300 to pass through, thereby hinged to the pedal seat 100 via the bushing 300.

[0037] During assembly, the hinge part 210 is first installed between the two side wall parts 110, so that the hinge hole 211 is aligned with the support holes 111 on both sides. Then, the bushing 300 is inserted, and the bushing 300 passes through the two support holes 111 and the hinge hole 211.

[0038] Preferably, the two ends of the bushing 300 are circumferentially fixed in the two support holes 111, the bushing 300 passes through the hinge hole 211, and the pedal arm 200 can rotate with the bushing 300 as the rotation center.

[0039] Both ends of the bushing 300 are firmly fixed in the support holes 111 of the side walls 110 of the pedal seat 100. The bushing 300 will not rotate relative to the pedal seat 100. The bushing 300 passes through the hinge hole 211 of the hinge part 210, so that the hinge part 210 (pedal arm 200) can rotate freely around the bushing 300.

[0040] like Figures 1 to 4 As shown, based on the above embodiment, the circumferential surface of the rotating shaft 400 is provided with a locking hole 410 extending radially therein, and the hinge part 210 is inserted with a locking pin 220. The locking pin 220 is inserted into the locking hole 410, and the hinge part 210 is circumferentially fixedly connected to the rotating shaft 400 through the locking pin 220.

[0041] The design ensures the circumferential fixed connection between the hinge part 210 and the rotating shaft 400 by opening the locking hole 410 extending radially on the circumferential surface of the rotating shaft 400 and inserting the locking pin 220 on the hinge part 210 into the hole. Specifically, the locking hole 410 extending radially is opened on the circumferential surface of the rotating shaft 400. When the locking pin 220 is inserted into the locking hole 410, the relative rotation of the rotating shaft 400 relative to the hinge part 210 can be prevented, so that the two can rotate synchronously. More ingeniously, the hinge part 210 rotates outside the shaft sleeve 300 around the axis of the shaft sleeve 300, and the rotating shaft 400 rotates inside the shaft sleeve 300 around the axis of the shaft sleeve 300, improving the flexibility of the entire motion system.

[0042] On the basis of the above-mentioned embodiments, the wall part of the shaft sleeve 300 is provided with a relief notch 310, the locking pin 220 passes through the relief notch 310 and is connected with the locking hole 410, and the locking pin 220 can move in the relief notch 310.

[0043] Since the shaft sleeve 300 is located between the rotating shaft 400 and the hinge part 210, if the locking pin 220 is directly installed on the hinge part 210 and tried to be inserted into the locking hole 410 of the rotating shaft 400, interference between components may occur. The design of the relief notch 310 is to avoid such interference and ensure that the locking pin 220 can be smoothly inserted into the locking hole 410. The relief notch 310 not only provides a path for the locking pin 220 to pass through the shaft sleeve 300, but also allows the locking pin 220 to move within a certain range to adapt to the displacement change when the pedal arm 200 rotates.

[0044] On the basis of the above-mentioned embodiments, the hinge part 210 is provided with a plug-in hole 212, the plug-in hole 212 is coaxially arranged with the locking hole 410, the plug-in hole 212 is arranged as a through hole structure, the locking pin 220 passes through the plug-in hole 212 and is inserted into the locking hole 410 through the relief notch 310.

[0045] The plug-in hole 212 is designed as a through hole structure, that is, it penetrates from one side to the other side, and the locking pin 220 can be inserted into the hinge part 210 from the outside, which is convenient for plugging the locking pin 220.

[0046] As shown in Figures 1 to 4 On the basis of the above-mentioned embodiments, the end of the rotating shaft 400 is provided with a magnetic steel 420, one side wall part 110 is provided with a shell, a circuit board 500 is installed in the shell, a Hall sensor is installed on the circuit board 500, and the end of the rotating shaft 400 passes through the one side wall part 110 and is close to the Hall sensor.

[0047] One end of the rotating shaft 400 is provided with a magnetic steel 420, which protrudes out of the side wall portion 110 and is as close to the Hall sensor as possible. This design allows the magnetic field change generated by the magnetic steel 420 when the rotating shaft 400 rotates to directly act on the Hall sensor. The magnetic steel 420 is installed at the outermost end of the rotating shaft 400 to ensure that it is closest to the Hall sensor, thereby improving the strength and clarity of the magnetic field signal. The Hall sensor is a sensor based on the Hall effect, which can detect changes in the magnetic field and convert these changes into an electrical signal. When the magnetic steel 420 rotates with the rotating shaft 400, the Hall sensor detects changes in the strength and direction of the magnetic field.

[0048] Since the end of the rotating shaft 400 directly protrudes through the side wall portion 110 and is close to the Hall sensor, the overall system structure is very compact, and the design of the magnetic steel 420 close to the Hall sensor improves the strength and clarity of the magnetic field signal, thereby enhancing the detection accuracy, and there is no need to provide a magnetic yoke on the rotating shaft 400.

[0049] As shown in Figure 4 , on the basis of the above-mentioned embodiments, the rotating shaft 400 is provided in a variable-diameter shaft structure with gradually changing diameters.

[0050] The diameter of the rotating shaft 400 gradually changes from one end to the other end. In the molding process such as injection molding or casting, the design of the variable-diameter shaft can significantly simplify the demolding process. Since the diameter gradually decreases, the mold can be easily pulled out from the end with the smallest diameter without jamming the rotating shaft 400, without the need for complex core-pulling mechanisms or lateral parting surfaces, thereby reducing the complexity and cost of the mold.

[0051] As shown in Figures 1 to 3 , on the basis of the above-mentioned embodiments, the outer peripheral surface of the rotating shaft 400 has at least one annular protrusion 430 protruding radially, and the annular protrusion 430 cooperates with the inner hole wall of the shaft sleeve 300.

[0052] The annular protrusion 430 is actually a stepped protrusion, so that the rotating shaft 400 as a whole forms a stepped shaft structure. The annular protrusion 430 forms a close fit with the inner hole wall of the shaft sleeve 300, ensuring the stability and rotation accuracy of the rotating shaft 400 in the shaft sleeve 300, while reducing the contact area between the rotating shaft 400 and the shaft sleeve 300, thereby reducing the resistance during rotation.

[0053] On the basis of the above-mentioned embodiments, spring seats 230 are installed on both sides of the hinged portion 210, and part of the spring seats 230 extends into the hinge hole 211 and is lined between the inner wall of the hinge hole 211 and the outer wall of the shaft sleeve 300.

[0054] Specifically, the inner wall of the hinge hole 211 is not in direct contact with the outer wall of the shaft sleeve 300, the part of the spring seat 230 extending into the hinge hole 211 is padded between the inner wall of the hinge hole 211 and the outer wall of the shaft sleeve 300, which plays a supporting role, and this design reduces the direct contact area and reduces the frictional resistance when rotating.

[0055] It should be noted that all directional indications, such as upper, lower, left, right, front, back, etc., are only used to explain the relative position relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications will also change accordingly.

Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0057] In the present application, unless otherwise specifically defined and limited, the terms "connection", "fixing" and the like should be understood broadly, for example, "fixing" can be fixed connection, or detachable connection, or integral; can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise specifically limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0058] In addition, the technical solutions of each embodiment of the present application can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection required by the present application.
