Technical Field
[0001] The utility model belongs to the technical field of vehicle parts and components, and relates to a hysteresis component and an electronic accelerator pedal. Background Art
[0002] With the rapid development of the transportation industry, more and more vehicles are appearing in people's daily lives, and cars have become the mainstream means of transportation. Electronic accelerator pedals are increasingly used in vehicles. Electronic accelerator pedals can output corresponding electrical signals according to the degree of pedaling to achieve throttle opening control.
[0003] In existing electronic accelerator pedals, in order to simulate the natural feeling of a mechanical accelerator and provide certain operational feedback, a design called a "hysteresis structure" is usually adopted. This hysteresis structure can increase the damping feeling of pedal operation, making the driving experience smoother and having a certain linearity. Among them, a part of the hysteresis structure adopts a wedge-shaped structure design, which is composed of two wedge-shaped blocks. These two wedge-shaped blocks are squeezed with the side wall of the base during the movement of the pedal, thereby generating the desired resistance effect.
[0004] However, in the actual production and assembly process, due to the small size and special shape of the wedge blocks, they are very likely to be misplaced or fall off when they are assembled to the front end of the pedal and the entire front end of the pedal is embedded in the base. This problem greatly increases the difficulty and time of assembly, and is one of the technical problems that need to be solved urgently in the current automotive parts manufacturing industry.

DETAILED DESCRIPTION
[0034] 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.
[0035] like Figure 1-6 As shown, a hysteresis assembly includes: a slider 100, the slider 100 has a first inclined surface 110 and a first guide seat 130; a bracket 200, the bracket 200 has a second inclined surface 210 and a first guide groove 230, the first guide seat 130 is installed in the first guide groove 230 and the bracket 200 is slidably connected with the slider 100, the first inclined surface 110 and the second inclined surface 210 are in contact with each other so that the slider 100 and the bracket 200 form a wedge-shaped mechanism; both side surfaces of the first guide seat 130 are provided with first protrusions 131, and both side wall surfaces of the first guide groove 230 are provided with first grooves 231, and the two first protrusions 131 are respectively located at the two first grooves 231 to limit the first guide seat 130 from being separated from the first guide groove 230.
[0036] The hysteresis assembly is mainly composed of a slider 100 and a bracket 200. The bracket 200 is mounted on the slider 100, and the second inclined surface 210 of the bracket 200 is in contact with the first inclined surface 110 of the slider 100 to form a wedge mechanism. The wedge mechanism means that when the bracket 200 is pressed down, the bracket 200 can push the slider 100 and the two can move to both sides respectively; the design of the first guide seat 130 and the first guide groove 230 can guide the movement of the bracket 200 and the slider 100, that is, the movement direction of the bracket 200 and the slider 100 is guided.
[0037] The two first protrusions 131 of the first guide seat 130 are located in the two first grooves 231 of the first guide slot 230. The length of the first groove 231 is greater than the stroke of the first protrusion 131. This design can constrain the first guide seat 130 in the first guide slot 230, so that the bracket 200 and the slider 100 form a whole; at the same time, it will not hinder the normal movement of the bracket 200 and the slider 100; specifically, because the two first protrusions 131 are in the two first grooves 231, the slider 100 and the bracket 200 can move relative to each other. At the same time, when the bracket 200 and the slider 100 have a tendency to separate (that is, when the first guide seat 130 has a tendency to disengage from the first guide groove 230), it is difficult for the two first protrusions 131 to disengage from the two first grooves 231, that is, it is difficult for the first guide seat 130 to disengage from the first guide groove 230; therefore, when the hysteresis assembly is assembled, the first guide seat 130 can be inserted into the first guide groove 230 to realize the assembly of the slider 100 and the bracket 200, and the overall structure formed by the assembly of the slider 100 and the bracket 200 is not easy to fall apart or disintegrate.
[0038] A hysteresis assembly that is easy to assemble is provided. The first guide seat 130 is inserted into the first guide groove 230 so that the slider 100 and the bracket 200 can be initially formed into a whole without affecting the relative movement between the slider 100 and the bracket 200.
[0039] like Figure 1-5 As shown, based on the above embodiment, the maximum distance between the outer end surfaces of the two first protrusions 131 and the spacing between the two side wall surfaces of the first guide groove 230 form an interference fit, and the maximum distance between the outer end surfaces of the two first protrusions 131 and the spacing between the two first grooves 231 form a clearance fit.
[0040] In this embodiment, because the first guide seat 130 has first protrusions 131 on both sides, the maximum width of the first guide seat 130 (i.e., the maximum distance between the outer end surfaces of the two first protrusions 131) is interference fit with the first guide groove 230, and the interference fit design makes it difficult for the first guide seat 130 to escape from the first guide groove 230; similarly, the maximum width of the first guide seat 130 is smaller than the spacing between the two first grooves 231, so that when the two first protrusions 131 are in the two first grooves 231, they will not hinder the sliding of the slider 100. This design enables the slider 100 and the bracket 200 to be assembled together without affecting the movement of the two.
[0041] On the basis of the above embodiment, the outer end surface of the first protrusion 131 is set as an arc surface. The advantage of this design is that when the bracket 200 and the slider 100 are assembled, the arc surface of the first protrusion 131 can ensure that the first guide seat 130 is smoothly inserted into the first guide groove 230, reducing the difficulty of assembly.
[0042] like Figure 1-6 As shown, based on the above embodiment, the slider 100 further has a first side surface 120, and the bracket 200 further has a second side surface 220, and the first side surface 120 and the second side surface 220 are respectively located on both sides of the hysteresis component; when the bracket 200 is subjected to pressure, the slider 100 and the bracket 200 move in opposite directions and the first side surface 120 and the second side surface 220 have a tendency to push out to both sides.
[0043] like Figure 1-4 As shown, on the basis of the above embodiment, the slider 100 further has a second guide seat 140 , and second protrusions 141 are disposed on both side surfaces of the second guide seat 140 .
[0044] In the actual structure, the slider 100 is connected to the pedal 300. In order to enable the slider 100 and the pedal 300 to be assembled together and not to be easily disassembled or separated, a second guide seat 140 and a second protrusion 141 located on both sides of the second guide seat 140 are specially provided. The second guide seat 140 is used to connect with the pedal 300, and the second protrusion 141 can limit the second guide seat 140 from being separated from the pedal 300.
[0045] Based on the above embodiment, the second protrusion 141 is configured as a buckle-shaped structure, which enables the second protrusion 141 to be smoothly inserted into the second guide groove 310 of the pedal 300 and provides greater resistance to separation when the second guide seat 140 tends to separate from the second guide groove 310 .
[0046] like Figure 1-4 As shown, an electronic throttle pedal includes a hysteresis assembly and a pedal 300, wherein a second guide groove 310 is provided at the end of the pedal 300, and a second guide seat 140 of a slider 100 is installed in the second guide groove 310 and the slider 100 is slidably connected to the pedal 300; the two side walls of the second guide groove 310 are provided with second groove portions 311, and the two second protrusions 141 of the second guide seat 140 are respectively located in the two second groove portions 311 to limit the second guide seat 140 from being separated from the second guide groove 310.
[0047] In this embodiment, the slider 100 is installed at the end of the pedal 300, and the end of the pedal 300 is provided with a second guide groove 310. The second guide block of the slider 100 is inserted into the second guide groove 310 and can slide along the second guide groove 310, thereby constraining the sliding direction of the slider 100; the second protrusion 141 of the second guide seat 140 is located in the two second groove portions 311 of the second guide groove 310, and the length of the second groove portion 311 is greater than the stroke of the second protrusion 141. This design can constrain the second guide seat 140 in the second guide groove 310, so that the slider 100 and the pedal The end of the plate 300 forms a whole; at the same time, it will not hinder the sliding of the slider 100 relative to the end of the pedal 300; specifically, since the two second protrusions 141 are in the two second grooves 311, the second guide seat 140 will not be hindered in the second guide groove 310 when the slider 100 slides; at the same time, when the slider 100 and the pedal 300 tend to separate (that is, when the second guide seat 140 tends to disengage from the second guide groove 310), the two second protrusions 141 are difficult to disengage from the two second grooves 311, that is, the second guide seat 140 is difficult to disengage from the second guide groove 310.
[0048] The electronic throttle pedal described above is very convenient to assemble the hysteresis assembly. The second guide seat 140 can be inserted into the second guide groove 310 to realize the assembly of the slider 100 and the pedal 300. The overall structure formed by the assembly of the slider 100 and the pedal 300 is not easy to fall apart or disintegrate.
[0049] In the actual assembly process, the slider 100 can be first assembled to the end of the pedal 300, that is, the second guide seat 140 is inserted into the second guide groove 310, and the two second protrusions 141 are located in the two second grooves 311, which makes it difficult for the slider 100 to fall off or separate from the pedal 300, and the second guide seat 140 can slide smoothly in the second guide groove 310; then the bracket 200 is assembled to the slider 100, that is, the first guide seat 130 is inserted into the first guide groove 230, and the two first protrusions 131 are located in the two first grooves 231, which makes it difficult for the bracket 200 to fall off or separate from the slider 100; after the assembly is completed, the hysteresis assembly and the end of the pedal 300 form a whole, and then are installed in the base 400. During the assembly process, the various parts are not easy to fall off or separate, which greatly reduces the difficulty of assembly.
[0050] It should be pointed out that, in the above-mentioned assembly process, the slider 100 and the bracket 200 may be assembled together to form a hysteresis assembly first, and then the hysteresis assembly may be assembled to the end of the pedal 300 .
[0051] Based on the above embodiment, the maximum distance between the outer end surfaces of the two second protrusions 141 forms an interference fit with the spacing between the two side wall surfaces of the second guide groove 310, and the maximum distance between the outer end surfaces of the two second protrusions 141 forms a clearance fit with the spacing between the two second grooves 311.
[0052] In this embodiment, because the second guide seat 140 has the second protrusions 141 on both sides, the maximum width of the second guide seat 140 (i.e., the maximum distance between the outer end surfaces of the two second protrusions 141) is interference fit with the second guide groove 310, and the interference fit design makes it difficult for the second guide seat 140 to escape from the second guide groove 310; similarly, the maximum width of the second guide seat 140 is smaller than the spacing between the two second grooves 311, so that when the two second protrusions 141 are in the two second grooves 311, they will not hinder the sliding of the slider 100. This design enables the slider 100 to be assembled with the pedal 300 without affecting the movement of the slider 100.
[0053] like Figure 1-7 As shown, based on the above embodiment, it also includes a base 400, the pedal 300 is hinged to the base 400 and the hysteresis component is located in the base 400; when the hysteresis component is in the hysteresis state, the first side 120 of the slider 100 and the second side 220 of the bracket 200 are respectively connected to the two side surfaces of the base 400.
[0054] Based on the above embodiment, a spring 410 is provided in the base 400, one end of the spring 410 is connected to the base 400 in abutment with each other and the other end is connected to the bracket 200 in abutment with each other; when the pedal 300 is stepped on, the spring 410 applies pressure to the bracket 200, thereby generating a hysteresis force between the first side surface 120 and the second side surface 220 and the two side surfaces of the base 400 respectively.
[0055] The working principle of the hysteresis component is as follows: the first side surface 120 and the second side surface 220 are respectively fitted with the two side surfaces of the base 400. When the pedal 300 is stepped on, the spring 410 presses the bracket 200, and the bracket 200 pushes the slider 100 downward, so that the bracket 200 and the slider 100 have a tendency to move in opposite directions. At this time, the first side surface 120 and the second side surface 220 respectively apply squeezing force to the two side surfaces of the base 400, thereby hindering the rotation of the pedal 300. When the pedal 300 is stepped on with a larger amplitude, the lateral squeezing force of the bracket 200 and the slider 100 is larger, and the hysteresis force generated is also larger.
[0056] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0057] In addition, in the present invention, the descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
[0058] In the present utility model, unless otherwise clearly stipulated and limited, the terms "connection", "fixed", etc. should be understood in a broad sense. For example, "fixed" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly limited.
[0059] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
