DETAILED DESCRIPTION

[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, an electronic accelerator pedal assembly includes:

[0032] A shell assembly having an installation cavity 110; a pedal 300, a front end of which is hinged in the installation cavity 110; a waterproof cover 400, which is fixed on the shell assembly; an electronic component, which is arranged between the shell assembly and the waterproof cover 400, and the electronic component is connected to the pedal 300.

[0033] The shell assembly is mainly the part connected to the front end of the pedal 300, and is mainly used for articulating the front end of the pedal 300. The electronic components are located on the side of the shell assembly and are connected to the pedal 300. When the pedal 300 is stepped on, the electronic components will generate an acceleration signal. After a waterproof cover 400 is provided on the shell assembly, the electronic components can be effectively protected from water ingress.

[0034] Specifically, the waterproof cover 400 is covered on the side of the shell to wrap up the entire electronic component, and the waterproof cover 400 is provided with a connector corresponding to the electronic component and the signal receiving device, so that the entire electronic component can be placed in a sealed environment.

[0035] The entire electronic accelerator pedal 300 assembly forms an integral waterproof sealing structure through the above arrangement, which can prevent water from entering, thereby making the entire accelerator pedal 300 safer and more reliable when in use.

[0036] like Figure 1 , Figure 2 As shown, based on the above embodiment, the shell assembly includes a base 100 and a middle cover 200, the installation cavity 110 is located on the base 100, and the base 100 and the middle cover 200 are mortise-jointed, so that the middle cover 200 covers the installation cavity 110.

[0037] The base 100 and the middle cover 200 are respectively located on both sides of the pedal 300 , and the base 100 has a mounting cavity 110 therein. The middle cover 200 is a cover structure for closing the base 100 .

[0038] In the traditional shell structure, the middle cover 200 and the base 100 are connected by screws, which is troublesome and has low tightness and flexibility. However, by using the mortise and tenon joint method, the base 100 and the middle cover 200 are fixed together, which is not only convenient for assembly, but also has very good tightness and flexibility.

[0039] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, based on the above embodiment, a receiving cavity 210 corresponding to the waterproof cover 400 is provided on the middle cover 200 , the electronic components are arranged in the receiving cavity 210 , and the waterproof cover 400 is fixed on the middle cover 200 to seal the receiving cavity 210 .

[0040] It is worth explaining here that the inner side of the middle cover 200 corresponds to the base 100, and the outer side corresponds to the waterproof cover 400; the accommodating cavity 210 is located on the waterproof cover 400, that is, the accommodating cavity 210 itself is an integrated structure, and its bottom wall is the middle cover 200, so water cannot penetrate into the accommodating cavity 210 from the middle cover 200, thereby effectively isolating the possibility of water penetrating from the installation cavity 110 to the accommodating cavity 210.

[0041] The electronic components are located in the accommodating cavity 210, and the waterproof cover 400 is sealed on the outside of the middle cover 200, so that the entire accommodating cavity 210 is sealed to form a waterproof structure; and this waterproof structure has high reliability and does not affect the operation of the electronic components while ensuring sealing.

[0042] like Figure 2 As shown, based on the above embodiment, a rotating shaft sleeve 310 is provided on the pedal 300, and an iron ring 320 for limiting and two magnets 330 are provided on the rotating shaft sleeve 310. The iron ring 320 is embedded in the rotating shaft sleeve 310, and the two magnets 330 are fixed on the iron ring 320 and arranged relatively.

[0043] The iron ring 320 can play the role of installing the magnet 330, so that the magnet 330 can be fixed on the rotating shaft sleeve 310. When the pedal 300 is stepped on, the magnetic field between the two oppositely arranged magnets 330 will change, thereby triggering the electronic component.

[0044] like Figure 3 , Figure 4 As shown, based on the above embodiment, the electronic component includes a Hall element 500 and a circuit board 600, one end of the Hall element 500 is arranged between the two magnets 330 and the other end is connected to the circuit board 600, the circuit board 600 is arranged in the accommodating cavity 210, and a plurality of pins 700 are arranged on the circuit board 600.

[0045] It is worth explaining here that the probe of the Hall element 500 is located between the two magnets 330 and does not move with the transmission of the rotating shaft sleeve 310. It is only used to detect changes in the magnetic field. The pins of the Hall element 500 are fixed on the circuit board to form a Hall circuit with the circuit board to send signals.

[0046] like Figure 1 , Figure 4 As shown, based on the above embodiment, the waterproof cover 400 is provided with a joint portion 410, the joint portion 410 is a long cavity structure, and a sealing block 420 is provided in the joint portion 410, and the sealing block 420 is provided with a plurality of small holes for the pins 700 to pass through.

[0047] The joint part 410 is actually a box-shaped structure with a long cavity, and the joint part 410 is not hollow, but a sealing block 420 with a separation function is arranged inside the joint part 410. The inner side of the connection between the joint part 410 and the waterproof cover 400 has a plurality of holes for the pins 700 to pass through. Specifically, the waterproof cover 400 is provided with a pin 700 hole, and this pin 700 hole is connected to the joint part 410.

[0048] The pin 700 is located in the long cavity of the joint part 410 and is penetrated through the small hole of the sealing block 420. The end of the pin 700 is bent toward one end of the waterproof cover 400, thereby passing through the pin 700 hole on the waterproof cover 400 and then connected to the circuit board. This can greatly improve the waterproof effect and ensure the sealing of the entire waterproof cover 400.

[0049] like Figure 5 , Figure 6As shown, on the basis of the above embodiment, the middle cover 200 is provided with a plurality of mortises 220 located at the edge position, and the base 100 is provided with a plurality of tenons 120 corresponding to the mortise grooves 220, and the tenons 120 are inserted into the mortise grooves 220, so that the base 100 and the middle cover 200 are mortised.

[0050] The tenon groove 220 is a long strip-shaped through-hole structure. The shape and structure of the tenon 120 are consistent with the tenon groove 220 and can be inserted into the tenon groove 220 .

[0051] It is worth pointing out here that, preferably, a plurality of plug connectors can be provided on the middle cover 200, and the plug connectors are located on the inner side of the middle cover 200. A plurality of sockets are provided on the base, and the plug connectors are inserted into the sockets to form mortise and tenon joints, which can improve the reliability of the connection.

[0052] like Figure 5 , Figure 6 As shown, on the basis of the above embodiment, a plurality of claws 230 are provided on the outer edge of the middle cover 200 , and the claws 230 hold the base 100 , so that the base 100 and the middle cover 200 are mortise-jointed.

[0053] It is worth mentioning here that the claw 230 is mainly used to grasp the outer edge of the base 100. At the same time, the tenon 120 is inserted into the tenon groove 220 to form the entire tenon structure, ensuring the reliability of the connection between the base 100 and the middle cover 200.

[0054] like Figure 5 , Figure 6 As shown, on the basis of the above embodiment, the positions of the claw 230 and the tenon 120 are arranged correspondingly, and the tenon 120 is provided with a first wedge-shaped protrusion 121, and the claw 230 is provided with a second wedge-shaped protrusion 231, and the first wedge-shaped protrusion 121 is buckled with the second wedge-shaped protrusion 231, so that the middle cover 200 and the base 100 are fixed.

[0055] It is worth explaining here that the tenon 120 is located on the inner side of the claw 230, and the positions of the tenon 120 and the claw 230 correspond, that is, the outer side of the tenon 120 is the claw 230, so when the middle cover 200 and the base 100 are mortised, the tenon 120 is inserted into the mortise 220, and several claws 230 all grasp the base 100, and the claws 230 and the tenon 120 are in a touching state; the first wedge-shaped protrusion 121 protrudes outward, and the second wedge-shaped protrusion 231 protrudes inward, so when the claw 230 and the tenon 120 are in a mortise state, the first wedge-shaped protrusion 121 and the second wedge-shaped protrusion 231 will be buckled together, thereby fixing the base 100 and the middle cover 200 together.

[0056] The mortise and tenon structure is formed by the mortise and tenon groove 220, the tenon 120 and the claw 230, and is fixed by the first wedge-shaped protrusion 121 and the second wedge-shaped protrusion 231. Not only is the structure ingenious, but it also saves the space required for the connection without the need for screw connection, making the entire shell assembly more miniaturized and having higher installation tightness and flexibility.

[0057] It is also worth pointing out here that the number of claws 230 and tenons 120 is preferably three, two of which are distributed at the front ends of the middle cover 200 and the base 100, and the last one is located at the sides of the middle cover 200 and the base 100.

[0058] The first wedge-shaped protrusion 121 is formed by an outer annular protrusion on the sheet-shaped tenon 120 and a wedge-shaped block extending from the annular protrusion toward the end of the tenon 120; the shape of the second wedge-shaped protrusion is similar to that of the first wedge-shaped protrusion 121. When the first wedge-shaped protrusion 121 is buckled with the second wedge-shaped protrusion 231, the two annular protrusions are buckled together, thereby fixing the two.

[0059] like Figure 3 , Figure 4 As shown, on the basis of the above embodiment, the middle cover 200 is provided with an outer edge 240 and an inner edge 250, the inner edge 250 is a closed structure to form a accommodating cavity 210, a plurality of screw hole columns 251 are provided on the inner edge 250, and a sealing edge 430 corresponding to the inner edge 250 is provided on the waterproof cover 400, the sealing edge 430 is embedded in the inner edge 250, and a plurality of screws passing through the screw hole columns 251 are provided on the waterproof cover 400.

[0060] The outer edge 240 is a structure formed by turning the edge of the middle cover 200 outward, and the inner edge 250 is a circle of surrounding edges set on the middle cover 200, so as to form a receiving cavity 210, and the circuit board is located in the receiving cavity 210.

[0061] A sealing edge 430 is provided on the inner side of the waterproof cover 400. The shape of the sealing edge 430 is the same as that of the inner edge 250, and only the size is different. The structure formed by the sealing edge 430 is smaller than the accommodating cavity 210 formed by the inner edge 250, so the sealing edge 430 can be embedded in the accommodating cavity 210, and preferably, the sealing edge 430 can be connected to the inner side of the inner edge 250. This structure can not only better position the waterproof cover 400 during installation, but also make the waterproof cover 400 more tightly connected to the middle cover 200, thereby ensuring waterproofness.

[0062] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
