Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive pedal. Background Technology

[0002] Automotive pedals typically feature snap-fit ​​structures to detachably connect mounting components such as sensors and wiring harness connectors. In related technologies, these snap-fit ​​structures usually employ a clip-on form. During assembly, mounting components such as sensors and wiring harness connectors are directly inserted into the pedal base, and the clips engage with the base to secure them. However, the clips need to be flexible and deformable during assembly to pass through structures such as mounting slots on the base. Therefore, it's difficult to further increase the structural strength of the clips, which in turn affects their tensile strength, potentially causing mounting components such as sensors and wiring harness connectors to easily detach from the base. Utility Model Content

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an automobile pedal to solve the technical problem that the mounting components are easily separated from the base in the prior art.

[0004] To achieve the above and other related objectives, this utility model provides a connector assembly, a base, and a limiting member. The connector assembly is mounted on the base along a first direction. The connector assembly has a first insertion structure, and the base has a second insertion structure. The first insertion structure and the second insertion structure cooperate to constrain the connector assembly in the opposite direction of the first direction. The first insertion structure moves along a second direction to disengage from the second insertion structure. The second direction is obliquely intersecting or perpendicular to the first direction. The limiting member is fixed on the base and abuts or connects to the connector assembly to maintain the cooperation between the first insertion structure and the second insertion structure.

[0005] Optionally, the first plug-in structure is a plug-in groove, the opening direction of the plug-in groove is opposite to the second direction, and the second plug-in structure is a protrusion that extends into the plug-in groove.

[0006] Optionally, the connector assembly includes a substrate, on which a pin is provided on one side facing the base, the root of the pin is connected to the substrate, and a snap-fit ​​portion is provided on the tip of the pin, the snap-fit ​​portion cooperating with the substrate to form the insertion groove.

[0007] Optionally, there are multiple pins, and the multiple pins are evenly distributed on the substrate.

[0008] Optionally, the base is provided with a mounting groove, the opening direction of the mounting groove is along the first direction, and the limiting member and the connector assembly are both located within the mounting groove.

[0009] The mounting groove has a first side and a second side that are arranged opposite to each other in the second direction. The connector assembly has a first abutting surface and a second abutting surface that are arranged opposite to each other in the second direction. The first abutting surface abuts against the first side, and the limiting member abuts between the second side and the second abutting surface.

[0010] Optionally, the limiting member includes a connecting portion, which is wedge-shaped and has a wedge tip for insertion between the second side and the connector assembly.

[0011] Optionally, the connecting part is provided with an elastic claw, and the limiting member is engaged with the base in the first direction by the elastic claw.

[0012] Optionally, the base is provided with a disassembly channel, which leads to the elastic claw on the limiting member.

[0013] Optionally, the limiting member includes a limiting portion whose second side surface cooperates with the second abutting surface to form a gap, the limiting portion abutting within the gap, and in the first direction, the outline of the projection of the limiting portion is the same as the outline of the gap.

[0014] Optionally, it also includes a pedal arm, the connecting end of which is rotatably disposed within the base, and the connector assembly is provided with a sensor for detecting the position of the pedal arm.

[0015] As described above, the automobile pedal of this utility model has the following beneficial effects: Since the automobile pedal includes a limiting member that abuts or connects with the connector assembly, the first plug-in structure and the second plug-in structure can maintain a fit. The fit between the first plug-in structure and the second plug-in structure can constrain the connector assembly in the opposite direction of the first direction. Compared with the connector assembly being connected to the base in the first direction through elastic structures such as buckles and claws, the constraint method of the first plug-in structure and the second plug-in structure constraining the connector assembly in the first direction does not require elastic deformation to install it in the base. Therefore, by increasing the structural strength of the first plug-in structure and the second plug-in structure, the tensile strength of the connector assembly in the pull-out direction can be increased, thereby helping to prevent the connector assembly from being accidentally pulled out of the base and improving the reliability of the product. Meanwhile, since the second direction is inclined to intersect or is perpendicular to the first direction, that is, the first direction and the second direction are not collinear or parallel to each other, when the connector assembly is subjected to a pull-out force in the pull-out direction, the connector assembly is less affected in the second direction. This helps to prevent the connector assembly from moving along the second direction and accidentally coming off the base, thus improving the reliability of the product. Attached Figure Description

[0032] Please see Figures 1-13 This embodiment provides an automotive pedal, including a connector assembly 2, a base 1, and a limiting member 6. The connector assembly 2 is mounted on the base along a first direction Z, the opposite direction of which is the pull-out direction of the connector assembly. The connector assembly 2 has a first insertion structure, and the base 1 has a second insertion structure. The first and second insertion structures cooperate to constrain the connector assembly 2 in the opposite direction of the first direction Z, i.e., the pull-out direction. The first insertion structure moves along a second direction X to disengage from the second insertion structure. The second direction X intersects or is perpendicular to the first direction Z. The limiting member 6 is fixedly positioned and abuts or connects to the connector assembly to maintain the cooperation between the first and second insertion structures.

[0033] When connector assembly 2 moves along the extension direction of the disengagement path, i.e., along the second direction X, the first insertion mechanism on connector assembly 2 can disengage from the engagement with the second insertion structure on the base, thereby releasing the constraint of the base on connector assembly 2 in the pull-out direction, and allowing connector assembly 2 to separate from the base. Limiting member 6 abuts against or connects to connector assembly 2, restricting the displacement of connector assembly in the second direction X, ensuring that the first insertion structure and the second insertion structure remain engaged, and thus keeping the base and connector assembly 2 in a snap-fit ​​state in the first direction Z, preventing connector assembly 2 from detaching from base 1 along the first direction Z.

[0034] Compared to the connection between the connector assembly 2 and the base 1 via elastic structures such as snaps and claws in the first direction Z, the constraint method of the first and second plug-in structures cooperating to constrain the connector assembly 2 in the first direction Z does not require elastic deformation for installation in the base, nor does it require consideration of the deformation of the first and second plug-in structures. Therefore, the structural strength of the first and second plug-in structures can be increased by thickening or other methods to increase the tensile strength of the connector assembly 2 in the pull-out direction, which helps to prevent the connector assembly 2 from being accidentally pulled out of the base, thereby improving the reliability of the product.

[0035] Meanwhile, in this embodiment, since the second direction X intersects or is perpendicular to the first direction Z at an angle, that is, the first direction Z and the second direction X are not collinear and are not parallel to each other, when the connector assembly 2 is subjected to a pull-out force in the pull-out direction, the influence on the connector assembly 2 in the second direction X is smaller. This is beneficial to reduce the movement of the connector assembly 2 along the second direction X when subjected to a pull-out force along the first direction Z, thereby helping to prevent the connector assembly 2 from accidentally coming off the base and improving the reliability of the product.

[0036] In this embodiment, the first direction Z and the second direction X are perpendicular to each other. When the connector assembly 2 is subjected to a pull-out force in the first direction Z, the connector assembly 2 will not be subjected to a component force generated by the pull-out force in the second direction X, further reducing the probability of the connector assembly 2 moving along the second direction X when subjected to the pull-out force.

[0037] like Figures 1-13 As shown, in this embodiment, the car pedal can be a brake pedal for controlling the braking of the car, or an accelerator pedal for controlling the acceleration of the car. In this embodiment, the car pedal is a brake-by-wire pedal. The brake-by-wire pedal transmits the operator's braking command to the car's brakes in the form of electronic signals through sensors. Compared with the mechanical structure in a traditional brake pedal, the braking command of the brake-by-wire pedal is more precise and the operation is more comfortable.

[0038] In this embodiment, the car pedal also includes a pedal arm 3, one end of which is rotatably disposed in the base 1, and a sensor for detecting the rotation of the pedal arm 3 is provided on the connector assembly 2.

[0039] Specifically, such as Figure 3 , Figure 4As shown, in this embodiment, the connector assembly 2 includes an insertion end 5 for insertion into the base 1. A sensor is disposed on the insertion end 5, which extends along the first direction Z to be inserted into the base 1 to detect positional information of the pedal arm 3, such as rotation angle. In this embodiment, the connector assembly 2 also has a connector port 4, which is positioned in the opposite direction of the first direction Z to protrude outside the base 1, thereby connecting to a connecting cable outside the base 1 to transmit the signal detected by the sensor.

[0040] In this embodiment, various types of sensors can be used, such as inductive sensors and Hall sensors. Taking a Hall sensor as an example, a magnet is installed on the rotation shaft of the pedal arm 3. When the pedal assembly is working, the magnet rotates relative to the base 1 along with the pedal arm 3. During the rotation of the magnet, its magnetic field changes. Since the angle of magnetic field rotation is related to the angle of pedal arm 3 rotation, the Hall sensor can sense the change in magnetic field and output a corresponding electrical signal, and feed this signal back to the vehicle control system to obtain the rotation angle of the pedal arm 3.

[0041] In some embodiments, the connector assembly 2 is provided with a protrusion 12 that protrudes in the opposite direction to the second direction X, and the base is provided with a plug groove 20 that has its opening direction in the same direction as the second direction X. The protrusion 12 extends into the plug groove 20, thereby constraining the connector assembly 2 in the pull-out direction.

[0042] like Figures 2 to 6 As shown, in this embodiment, the connector assembly 2 is provided with a plug groove 20, the opening direction of the plug groove 20 is opposite to the second direction X, and the base is provided with a protrusion 12, which protrudes towards the second direction X and extends into the plug groove 20 to constrain the connector assembly 2 in the pull-out direction.

[0043] Specifically, in this embodiment, the connector assembly 2 includes a substrate 21, with a plug interface disposed on one side of the substrate 21 and an insertion end 5 disposed on the other side of the substrate 21. A pin is also provided on the side of the substrate 21 where the insertion end 5 is disposed, i.e., the side facing the interior of the base 1. When the connector assembly 2 is connected to the base 1, the pin extends into the base 1 along with the insertion end 5. The tail end of the pin is connected to the substrate 21, and a snap-fit ​​portion 22 is provided on the head end of the pin. The snap-fit ​​portion 22 cooperates with the substrate 21 to form the aforementioned insertion groove 20.

[0044] In this embodiment, the protrusion 12 is located inside the base 1. When the connector assembly 2 is inserted into the base 1 along the first direction Z, the insertion groove 20 and the protrusion 12 are at the same height in the first direction Z, that is, the insertion groove 20 and the protrusion 12 are aligned. When the connector assembly 2 moves in the opposite direction X, the protrusion 12 can extend into the insertion groove 20. When the connector assembly 2 is in place, the insertion groove 20 and the protrusion 12 cooperate with each other, which can constrain the connector assembly 2 in the pull-out direction, thereby preventing the connector assembly 2 from coming off the base 1 in the opposite direction Z.

[0045] like Figures 1-4 As shown, in this embodiment, there can be multiple pins, which are evenly arranged to improve the limiting effect of the base 1 docking with the plug component 2.

[0046] The limiting members can be arranged at multiple positions to constrain the position of the connector assembly 2 and prevent it from shifting along the second direction X. In some alternative embodiments, the limiting members can be positioned opposite to the second direction X relative to the connector assembly 2. The limiting members pull the connector assembly 2 in the opposite direction X, preventing it from moving along the second direction X and disengaging from the connector assembly.

[0047] The limiting member 6 blocks the connector assembly 2 in the second direction X to prevent the connector assembly 2 from moving along the second direction X and disengaging from the connector assembly 2. Compared to pulling the connector assembly 2 in the opposite direction X, the limiting member 6 blocks the connector assembly 2 without needing to be connected to it, resulting in a simpler structure and reducing product costs.

[0048] Specifically, such as Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, a mounting groove 10 is provided on the base 1. The opening direction of the mounting groove 10 is opposite to the first direction Z. The connector assembly 2 can be inserted into the base 1 through the mounting groove 10.

[0049] Both the limiting member 6 and the connector assembly 2 are disposed within the mounting groove 10. The mounting groove 10 has a first side and a second side disposed opposite to each other in the second direction X. The connector assembly 2 has a first abutting surface and a second abutting surface disposed opposite to each other in the second direction X. The first abutting surface abuts against the first side, and the limiting member 6 abuts between the second side and the second abutting surface. After the limiting member 6 is installed between the second side and the second abutting surface, the second side abuts against the limiting member 6 in the opposite direction of the second direction X, thereby enabling the limiting member 6 to abut and limit the connector assembly 2.

[0050] In this embodiment, the limiting member 6 is detachably mounted on the base 1 in the opposite direction of the first direction Z. The detachable nature of the limiting member 6 allows for connection or disconnection between the limiting member 6 and the base, facilitating product assembly or maintenance. The detachable nature of the limiting member 6 in the pull-out direction differs from the second direction X, preventing excessive force on the limiting member 6 in the second direction X and ensuring its effective positioning of the connecting plug assembly 2.

[0051] Specifically, in this embodiment, the limiting member 6 includes a connecting portion, which is wedge-shaped with a wedge tip. The wedge tip is used to insert between the second side surface and the connector assembly 2, facilitating the installation of the limiting member 6 between the second side surface and the connector assembly 2. In this embodiment, the limiting member includes a limiting portion. The second side surface and the second abutting surface cooperate to form a gap 11. The limiting portion abuts within the gap 11. In the first direction, the outline of the projection of the limiting portion is the same as the outline of the gap 11. After the limiting member 6 is installed, the limiting portion of the limiting member 6 is inserted into the gap 11. The limiting portion and the connector assembly 2 together seal the opening of the mounting groove 10, which helps to prevent dust and debris from entering the base 1 from the mounting groove 10, thereby improving the reliability of the product.

[0052] Specifically, in this embodiment, the connecting portion of the limiting member 6 is provided with an elastic claw 61. The limiting member 6 is engaged with the base 1 in the opposite direction of the first direction Z, i.e., the pull-out direction, through the elastic claw 61. The elastic claw 61 has a simple structure and is easy to install, which helps to improve the assembly efficiency of the car pedal. In this embodiment, the base is provided with a disassembly channel, which leads to the elastic claw 61 on the limiting member 6. The elastic claw 61 can be compressed through the disassembly channel, facilitating the disassembly of the limiting member 6.

[0053] like Figures 1-13 As shown in the figure, in this embodiment, the connector assembly 2 of the car pedal, during actual installation, is as follows: Figure 5 and Figure 6 As shown, first insert the insertion end 5 of the connector assembly 2 into the mounting slot 10 of the base 1 along the first direction Z until the insertion slot 20 on the connector assembly 2 is aligned with the protrusion 12 in the base 1. After the insertion slot 20 on the connector assembly 2 is aligned with the protrusion 12 in the base 1, as shown... Figure 7 and Figure 8 As shown, the connector assembly 2 is moved in the opposite direction of the second direction X, so that the protrusion 12 of the base 1 is inserted into the insertion slot 20 until the connector assembly 2 abuts against the first side of the mounting slot 10. Figure 9 As shown, after the connector assembly 2 abuts against the first side of the mounting slot 10, the limiting member 6 is inserted into the gap 11. Figure 12 and Figure 13As shown, after inserting the limiting member 6 into the gap 11, the installation of the connector assembly 2 is completed. In this embodiment, the mounting groove 10 can be provided with structures such as limiting steps to cooperate with structures such as the base plate 21 on the connector assembly 2, so as to limit the connector assembly 2 in the first direction Z, so that after the connector assembly 2 is inserted into the mounting groove 10, the insertion groove 20 on the connector assembly 2 is aligned with the protrusion 12 in the base 1, which makes it easy for the protrusion 12 of the base 1 to be accurately engaged in the insertion groove 20, reducing the installation difficulty of the connector assembly 2.

[0054] In summary, the automotive pedal provided in this embodiment, compared to a connector assembly connected to a base in the first direction via elastic structures such as clips and claws, uses a first and second insertion structure to constrain the connector assembly in the first direction. This method eliminates the need to consider the deformation of the first and second insertion structures, thus increasing their structural strength to enhance the pull-out strength of the connector assembly in the pull-out direction. This helps prevent the connector assembly from accidentally pulling out of the base, thereby improving product reliability. Furthermore, since the second direction is inclined or perpendicular to the first direction (i.e., the first and second directions are not collinear or parallel), the impact on the connector assembly in the second direction is smaller when subjected to pull-out force in the pull-out direction. This helps prevent the connector assembly from moving along the second direction and accidentally detaching from the base, further improving product reliability.

[0055] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
