Description

Technical Field

[0001] This utility model relates to the field of accelerator pedal structure technology, specifically a Hall effect sensing accelerator pedal structure. Background Technology

[0002] Currently, the low-speed vehicle market is widespread, with strong demand in short-distance travel, logistics, and sharing sectors. New energy low-speed vehicles mainly refer to low-speed electric vehicles used for short-distance commuting. They are typically characterized by affordable prices and practical configurations, making them suitable for daily commuting, picking up and dropping off children, and other similar scenarios. The accelerator pedal assembly of a new energy low-speed vehicle is the core component that controls the vehicle's power output. Its core function is to convert the driver's acceleration intention into an electrical signal, thereby precisely controlling the power output of the electric motor. Unlike gasoline vehicles, which control the throttle valve through a mechanical cable, the accelerator pedal of a new energy vehicle adopts an electronic design, typically including an accelerator pedal and a position sensor.

[0003] The accelerator pedal in the prior art consists of a pedal arm, a housing, a spring, and an integrated control board. It mainly uses non-contact technologies such as Hall sensors or potentiometers to detect the pedal opening and rate of change in real time and transmit the signal to the motor controller. The integrated control board inside the pedal is responsible for converting the sensor signal into a standard voltage signal and transmitting it to the vehicle controller. When the pedal is pressed, the spring contracts, driving the magnetic mechanism to rotate and changing the magnetic field of the coil to generate an electrical signal.

[0004] While the aforementioned existing technologies have significant beneficial effects, they still have shortcomings:

[0005] The aforementioned accelerator pedal structure is quite common in the market. Due to the fixed models of various parts, specific production lines and tooling are required to assist in production and installation. This makes it difficult to assemble the entire pedal assembly. At the same time, the design of components such as springs is simple and does not meet the pedal feel requirements of different customers. Furthermore, the electrical signal cannot be adjusted, which cannot meet the different needs of customers. Therefore, a Hall effect sensing accelerator pedal structure is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a Hall effect sensor-type accelerator pedal structure. By combining the pedal housing with the main shaft, installation only requires structural fixing and tightening with self-tapping screws, simplifying the assembly process of the pedal housing and pedal arm. No specific production line tooling is required, and the position of the magnet at the base of the pedal arm can be adjusted by multiple sets of magnet holes, providing adjustability during installation to meet different needs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a Hall effect sensor-type accelerator pedal structure, comprising a pedal body, a pedal arm axially connected to one end of the pedal body, the pedal body including a pedal housing, and a mounting base fixed to the bottom surface of the pedal housing, mounting holes being provided at the four peripheral ends of the mounting base, a spring limiting groove being fixed inside the top end of the pedal housing, and a spring being fitted at the bottom of the spring limiting groove, a mold gate being provided on one side of the top end of the pedal housing, an installation cavity being provided inside one end of the pedal housing, and a spindle positioning hole being provided on one side of the installation cavity, a spindle being fitted on one side of the spindle positioning hole, and a self-tapping screw being connected to one side of the spindle, a PCBA board being snapped into the rear end of one side of the outer wall of the pedal housing, and a PCBA protective cover being provided on the outer wall of the PCBA board, and a wire harness being soldered to one side of the outer wall of the PCBA board.

[0008] Preferably, the pedal housing forms an elastic rotating structure with the pedal arm via a main shaft and a spring, and the main shaft is fixed to one side of the pedal housing by a self-tapping screw.

[0009] Preferably, the top end of the spring is embedded in the mounting cavity through a spring limiting groove, and the bottom end of the spring is in contact with the root of the pedal arm.

[0010] Preferably, the PCBA board is thermally riveted to one side of the outer wall of the pedal housing, and the PCBA board is electrically connected to the wire harness.

[0011] Preferably, the pedal housing is integrally fixedly connected to the mounting base, and the mounting base has multiple sets of mounting holes on its four perimeter edges.

[0012] Preferably, the pedal arm includes a pedal arm frame, and the pedal arm frame is fixed with cross ribs inside. The top of the pedal arm frame is fixed with a pedal platform, and the bottom of the pedal arm frame is provided with a main shaft ring hole.

[0013] Preferably, the inner wall size of the magnet hole matches the size of the magnet, and the magnet hole is opened vertically and vertically along the root of the pedal arm.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model simplifies the assembly process of the pedal housing and pedal arm by using a combination of pedal housing and main shaft insertion, requiring only structural fixing and tightening with self-tapping screws.

[0016] 2. The accelerator pedal structure's arm frame enhances strength and rigidity through the arrangement of cross ribs. At the same time, twelve ribs are added to the two rings at the main shaft ring hole position, resulting in better stress distribution under positive force. Furthermore, the position of the magnets can be reasonably arranged according to the IC and customer electrical signal requirements. The mold adopts a multi-set magnet hole design, which can assist in replacing inserts. The position is variable, providing adjustability during the installation process.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This embodiment of a Hall effect sensor-type accelerator pedal structure includes a pedal body 1, with a pedal arm 2 axially connected to one end of the pedal body 1. The pedal body 1 includes a pedal housing 101, and a mounting base 102 is fixed to the bottom surface of the pedal housing 101. Mounting holes 103 are provided on the four periphery of the mounting base 102. A spring limiting groove 104 is fixed inside the top end of the pedal housing 101, and a spring 105 is sleeved at the bottom of the spring limiting groove 104. A mold is provided on one side of the top end of the pedal housing 101. The pedal housing 101 has a gate 106. An installation cavity 107 is provided inside one end of the pedal housing 101. A spindle positioning hole 108 is provided on one side of the installation cavity 107. A spindle 109 is fitted on one side of the spindle positioning hole 108. A self-tapping screw 110 is connected to one side of the spindle 109. A PCBA board 111 is snapped into the rear end of one side of the outer wall of the pedal housing 101. A PCBA protective cover 112 is provided on the outer wall of the PCBA board 111. A wire harness 113 is soldered to one side of the outer wall of the PCBA board 111.

[0026] like Figure 1-5As shown, the accelerator pedal structure in this utility model is similar to the existing accelerator pedal structure. The main improvement of this utility model lies in the combination of the pedal housing 101 and the main shaft 109. Installation only requires structural fixing and tightening with self-tapping screws 110, simplifying the assembly process of the pedal housing 101 and the pedal arm 2. No specific production line tooling is required. Furthermore, the position of the magnet 206 at the base of the pedal arm 2 can be adjusted by multiple sets of magnet holes 205, providing adjustability during installation to meet different needs. In this utility model, the PCBA board 111 and PCBA... The Hall sensors on board 111 are all existing technology. When using this accelerator pedal structure, first insert the pedal arm 201 into the mounting cavity 107, then fit the spring 105 into the spring limiting groove 104, keeping the root of the pedal arm 201 against the bottom of the spring 105. Then, insert the spindle 109 into the spindle positioning hole 108 and pass it through the spindle ring hole 204 of the pedal arm 201. Tighten the self-tapping screw 110 to the spindle 109 to fix it. Then, solder the connector of the wiring harness 113 to the PCBA board 111 to fix it. Finally, snap the PCBA board 111 into the pedal. The Hall sensor on the PCBA board 111 is aligned with the root of the pedal arm 2 in the groove on one side of the outer wall of the board housing 101. The PCBA protective cover 112 can then be placed on top and secured with self-tapping screws 110, completing the assembly process. During use, the pedal arm 2, in conjunction with the internal magnet 206, can be used to detect the pedal opening and rate of change in real time, transmitting the signal to the motor controller. This pedal structure utilizes a combination of the pedal housing 101 and the main shaft 109, requiring only structural fixing and tightening with self-tapping screws 110 to secure the pedal housing 101. The assembly process of pedal arm 1 and pedal arm 2 is simplified, eliminating the need for specific production line tooling. At the same time, different springs 105 can be fitted to meet the pedal feel requirements of various customers. Multiple mounting holes 103 are designed on the mounting base 102, which can be installed at three points according to different customer needs. The top center of the pedal housing 101 is designed with a structure for arranging the mold gate 106, making molding more convenient. The main shaft positioning hole 108 on one side ensures that the main shaft 109 is positioned during pedal operation without replacement, resulting in a more realistic pedal feel. Combined with the uniform arc support rib structure on both sides of the shaft shoulder, the strength and reliability are maintained.

[0027] like Figure 2-5As shown, the pedal arm 2 includes a pedal arm frame 201, and a cross rib 202 is fixed inside the pedal arm frame 201. A pedal platform 203 is fixed at the top of the pedal arm frame 201, and a main shaft ring hole 204 is opened at the bottom of the pedal arm frame 201. Multiple sets of magnet holes 205 are opened on one side of the root of the pedal arm frame 201, and magnets 206 are embedded inside the magnet holes 205. Before installation, the corresponding magnets 206 need to be inserted into the magnet holes 205 and hot-riveted. Once fixed, the pedal arm 201 can be installed on the pedal housing 101. The pedal arm 201 has increased strength and rigidity through the arrangement of cross ribs 202. At the same time, twelve ribs are added to the two rings at the position of the main shaft ring hole 204, which makes the force under positive force better. The position of the magnet 206 can be reasonably arranged according to the IC and customer electrical signal requirements. The mold adopts a design with multiple sets of magnet holes 205, which can assist in the replacement of inserts. The position is variable and has adjustability during the installation process.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
