Description

Technical Field

[0001] This utility model relates to the field of brake pedal technology, specifically a brake pedal with a replaceable structure. Background Technology

[0002] The brake pedal is a core braking component in vehicles and equipment such as automobiles and construction machinery, directly affecting operational safety and convenience. Different operators have different leg lengths, resulting in varying requirements for brake pedal height; furthermore, the pedal itself is prone to wear and tear after prolonged use, necessitating replacement.

[0003] Currently, most traditional brake pedals are one-piece structures with a fixed and non-adjustable height, which cannot accommodate people with different leg lengths and can cause inconvenience for some operators. Some adjustable pedals lack a precise alignment structure, requiring repeated attempts to align the positioning components during adjustment, resulting in low disassembly and assembly efficiency. In view of this, we propose a brake pedal with a replaceable structure. Utility Model Content

[0004] The main objective of this invention is to provide a brake pedal with a replaceable structure, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a brake pedal with a replaceable structure, comprising a pedal arm and a pedal body. A fixing seat is fixedly connected to the end face of the pedal arm, and a plug rod is fixedly connected to the bottom of the pedal body. A guide slot is provided on the fixing seat, and a positioning rod is slidably connected to the inner wall of the fixing seat. The positioning rod and the fixing seat are elastically connected by a spring, and a dial is fixedly connected to the end of the positioning rod away from the fixing seat.

[0006] Preferably, the insertion rod and the guide slot are slidably connected. The guide slot limits the movement direction of the insertion rod to prevent it from rotating, thus facilitating the connection between the insertion rod and the positioning rod.

[0007] Preferably, the insertion rod has a fixed height through hole, and multiple sets of fixed height through holes are provided. When the positioning rod is inserted into the fixed height through holes of different heights, it causes the position of the insertion rod on the fixed seat to change, thereby changing the position of the pedal body and making it convenient for people of different heights to use.

[0008] Preferably, the positioning rod is slidably connected to the fixed height through hole.

[0009] Preferably, the insertion rod is provided with a position reference ring groove, and multiple sets of position reference ring grooves are provided. The length of the reference ring groove is the same as the thickness of the fixing seat. By making the reference ring groove at the corresponding position complete in the guide slot, the alignment of the fixed height through hole and the positioning rod is completed, which makes it convenient for the positioning rod to slide into the fixed height through hole and complete the alignment work conveniently.

[0010] Preferably, the guide slot has an installation hole, and a magnet is embedded in the installation hole. The magnet magnetically engages with the positioning rod, thereby enhancing the positioning stability of the positioning rod inserted into the guide slot and preventing the positioning rod from loosening and detaching during the use of the brake pedal.

[0011] Preferably, the guide slot has a storage slot, and a blocking block is engaged with the storage slot. The blocking block blocks the spring to prevent debris from entering between the springs and affecting the spring's compression.

[0012] This utility model provides a brake pedal with a replaceable structure. It has the following advantages: (1) The brake pedal insert with the replaceable structure is provided with multiple sets of fixed height through holes. The positioning rod can be inserted into the through holes of different heights, driving the pedal body to move up and down along the guide slot to adjust the height position of the pedal body. Combined with the anti-rotation limit of the insert rod by the guide slot, it ensures that the pedal body is stable and does not shake after adjustment, which can be adapted to operators with different leg lengths, avoids operation fatigue or braking delay caused by unsuitable pedal height, and improves the adaptability of use.

[0013] (2) The position reference ring groove of the brake pedal insert rod with the replacement structure matches the thickness of the fixing seat. When the ring groove is fully embedded in the guide slot, the fixed height through hole and the positioning rod are automatically aligned. There is no need for repeated adjustment, which greatly improves the connection efficiency of the insert rod and the positioning rod. The magnet can enhance the magnetic fixation of the positioning rod and the through hole and prevent the positioning rod from loosening and falling off during use. The shielding block can block the debris from entering the spring area and avoid the spring from jamming. The shielding block can also prevent the positioning rod from displacing a large distance, ensuring the connection status of the positioning rod and the insert rod, taking into account both the convenience of disassembly and assembly and the reliability of long-term use.

[0017] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model proposes a brake pedal with a replaceable structure, including a pedal arm 1 and a pedal body 2. The pedal arm 1 is made of high-strength alloy steel with a rust-proof surface. One end is connected to the vehicle's braking mechanism, and the other end is fixed to a mounting base 3 by welding to ensure load-bearing capacity. The pedal body 2 is made of engineering plastic with anti-slip textures on the surface to prevent slipping and improve operational safety. The mounting base 3 is fixedly connected to the end face of the pedal arm 1, and a rod 4 is fixedly connected to the bottom of the pedal body 2. A guide slot 5 is provided on the mounting base 3, and a positioning rod 6 is slidably connected to the inner wall of the mounting base 3. The positioning rod 6 has a protrusion, and the positioning rod 6 is elastically connected to the mounting base 3 by a spring. A toggle disc 7 is fixedly connected to the end of the positioning rod 6 away from the mounting base 3.

[0020] In this invention, the insertion rod 4 is slidably connected to the guide slot 5. The guide slot 5 limits the movement direction of the insertion rod 4 to prevent it from rotating, facilitating the connection between the insertion rod 4 and the positioning rod 6. The insertion rod 4 has a fixed height through hole 8, and multiple sets of fixed height through holes 8 are provided. When the positioning rod 6 is inserted into the fixed height through holes 8 of different heights, it causes the position of the insertion rod 4 on the fixed base 3 to change, thereby changing the position of the pedal body 2, making it convenient for people of different heights to use. The positioning rod 6 is slidably connected to the fixed height through hole 8.

[0021] Furthermore, the insertion rod 4 is provided with a position reference ring groove 9. The position reference ring groove 9 is an annular groove with white marking lines on the groove wall for easy identification by operators. Each set of position reference ring grooves corresponds to a set of fixed height through holes 8. There are multiple sets of position reference ring grooves 9. The length of the reference ring groove 9 is the same as the thickness of the fixing seat 3. By making the corresponding position reference ring groove 9 complete in the guide slot 5, the alignment of the fixed height through hole 8 and the positioning rod 6 is completed, making it easy for the positioning rod 6 to slide into the fixed height through hole 8 and complete the alignment work conveniently.

[0022] Furthermore, the guide slot 5 is provided with a mounting hole 10, which is a circular blind hole located on the inner wall of the guide slot 5 and corresponding to the positioning rod 6. This ensures that the magnet 11 can be accurately magnetically attracted to the positioning rod 6. The mounting hole 10 is inlaid with a magnet 11, which is a neodymium iron boron strong magnet with a nickel-plated surface for rust prevention. The magnet 11 and the positioning rod 6 are magnetically attracted to each other, which enhances the stability of the positioning rod 6 inserted into the insert rod 4 and prevents the positioning rod 6 from loosening and falling off during the use of the brake pedal.

[0023] Furthermore, the guide slot 5 has a storage slot 12, which is a rectangular slot corresponding to the position of the spring. This facilitates the engagement of the blocking block 13. The inner wall width of the storage slot 12 is greater than the protrusion of the positioning rod 6, making it easier for the positioning rod 6 to move into the storage slot 12 and be stored in it. The blocking block 13 is engaged with the storage slot 12. The blocking block 13 is an elastic plastic block that blocks the spring, preventing debris from entering between the springs and affecting their compression. At the same time, when the magnet 11 cannot magnetically attract the positioning rod 6, the blocking block 13, positioned in the storage slot 12, blocks the movement of the positioning rod 6, ensuring the connection between the positioning rod 6 and the insertion rod 4 and improving the stability of the device.

[0024] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0025] When using the pedal body 2, if it is necessary to adjust the height of the pedal body 2 or replace the pedal body 2, first remove the blocking block 13 from the storage slot 12 to remove the obstruction of the positioning rod 6 boss and prevent the positioning rod 6 from being unable to achieve a large displacement; then manually pull the dial 7 to drive the positioning rod 6 to compress the spring and move it away from the guide slot 5, so that the positioning rod 6 is completely separated from the current fixed height through hole 8; if the pedal body 2 is replaced, directly pull the plug rod 4 out of the guide slot 5 and replace the plug rod 4 with the new pedal body 2. If the height is adjusted, insert the rod 4 back into the guide slot 5 and observe the position reference groove 9 on the rod 4. When the groove corresponding to the target height is fully embedded in the guide slot 5, the fixed height through hole 8 is just aligned with the positioning rod 6. At this time, release the dial 7, and the spring pushes the positioning rod 6 to slide into the fixed height through hole 8. The magnet 11 and the positioning rod 6 magnetically cooperate to enhance the fixation. If the magnet 11 fails, the boss of the positioning rod 6 will be blocked by the blocking block 13 during subsequent use, which will limit the excessive movement of the positioning rod 6 and ensure that it maintains a fit with the fixed height through hole 8.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
