Description

Technical Field

[0001] This utility model relates to the field of foot pedal technology, specifically a heated, height-adjustable foot pedal. Background Technology

[0002] In office, home, and leisure settings, footrests are commonly used devices to help users maintain a comfortable sitting posture. Their core function is to provide stable foot support for users in a seated position. Placing the feet on the footrest prevents leg muscle tension and poor blood circulation caused by dangling feet, alleviating leg fatigue from prolonged sitting and helping to maintain a natural and comfortable posture, thus improving the physical experience during long periods of sitting or leisure. However, in actual use, different users have different needs for footrest support angles due to differences in sitting habits and leg physiology. Existing footrests have significant shortcomings: most have a fixed angle structure, which cannot meet the needs of personalized angle adjustment, resulting in discomfort for some users; the few products with angle adjustment functions require complex actions such as unlocking the latch, manually flipping the support surface, or rotating the adjustment knob. Users need to interrupt their sitting posture, bend over, or turn to the side to operate, making the process cumbersome and difficult to accurately locate the desired angle, seriously affecting ease of use and experience. Therefore, current footrests with height adjustment functions have significant deficiencies in angle adjustment flexibility and ease of operation, failing to fully meet user needs.

[0003] Therefore, this utility model provides a heated, liftable foot pedal. Utility Model Content

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 A heated lifting foot pedal includes a U-shaped support base 1 and a pedal 2. Two vertical fixing plates 11 are installed at the top of the U-shaped support base 1. The two vertical fixing plates 11 are symmetrically distributed. Lifting side plates 12 are inserted into the outer side of each of the two vertical fixing plates 11. Two horizontal sliding rods 3 are provided on the pedal 2.

[0020] The pedal 2 has two connecting ears 21 installed at its bottom, and the two connecting ears 21 are rotatably connected to one side of the corresponding lifting side plate 12.

[0021] It should be noted that the pedal 2 described in this embodiment is rotated between the two lifting side plates 12 via two connecting ears 21.

[0022] Two guide holes 22 are provided on the pedal 2. Two horizontal slide rods 3 are slidably connected to the inner wall of the corresponding guide holes 22. Limiting blocks 31 are installed on the opposite side of the two horizontal slide rods 3. Several limiting holes 121 are provided on one side of the two lifting side plates 12. The limiting blocks 31 are engaged and connected to the inner wall of the corresponding limiting holes 121.

[0023] It should be noted that, in this embodiment, the pedal 2 is mutually limited by the guide hole 22 and the transverse slide bar 3, so that when the limiting plug 31 is inserted into the limiting hole 121, the transverse slide bar 3 and the pedal 2 can be limited in angle.

[0024] Both transverse slide bars 3 have foot-push crossbars 32 installed at their top ends, and both foot-push crossbars 32 are slidably connected to the top end of the pedal 2.

[0025] It should be noted that the foot-operated crossbar 32 described in this embodiment is designed to facilitate contact with the user's foot, enabling rapid foot adjustment.

[0026] Specifically, when the angle of pedal 2 needs to be adjusted, the user pushes the two foot-operated crossbars 32 outwards with both feet. Since the foot-operated crossbars 32 are connected to the top of the transverse slide bar 3, they will cause the transverse slide bar 3 to slide within the guide hole 22 of pedal 2. This will cause the limiting block 31 on the opposite side of the transverse slide bar 3 to move away from the lifting side plate 12 and be pulled out of the limiting hole 121, thus releasing the restriction on the angle of pedal 2. At this time, the user presses on pedal 2, and the bottom connecting ear 21 of pedal 2 is rotated to connect with the lifting side plate 12. The pedal 2 can be rotated around the pivot of the connecting ear 21 to a suitable angle that conforms to one's sitting posture and leg structure. An elastic component is provided between the transverse slide bar 3 and the lifting side plate 12. Once the angle is determined, the elastic component will pull the transverse slide bar 3 back, causing the limiting insert 31 to re-insert into the corresponding limiting hole 121 of the lifting side plate 12, thus automatically locking the angle of the pedal 2 and ensuring stable support. Height adjustment is achieved through the extension and retraction of the lifting side plate 12 and the vertical fixing plate 11. Adjusting the lifting side plate 12... The insertion depth on the vertical fixing plate 11 can change the overall height of the pedal 2, adapting to the needs of users of different heights and furniture of different heights such as office chairs and sofas. Through the insertion and cooperation of the lifting side plate 12 and the vertical fixing plate 11, the height of the foot pedal can be flexibly adjusted, solving the problem of poor adaptability of traditional fixed-height foot pedals, meeting the usage needs of users of different heights and furniture height scenarios, and expanding the scope of application. Through the cooperation structure of the foot-push crossbar 32, the horizontal slide bar 3, the limiting plug 31 and the limiting plug hole 121, the user only needs to operate the foot-push crossbar 32 with their foot to quickly release the angle restriction of the pedal 2 and make adjustments. After the adjustment is completed, the elastic component automatically pulls back and locks, eliminating the need for cumbersome actions such as unlocking the buckle, manually flipping or rotating the adjustment knob, and eliminating the need to interrupt the sitting posture, bend over or turn to the side. This greatly improves the convenience and accuracy of angle adjustment, meets the personalized needs of different users for the foot pedal support angle, and effectively solves the defects of insufficient flexibility and ease of operation of existing foot pedal angle adjustment.

[0027] In one embodiment of this utility model, such as Figures 1-4 As shown, a temperature control plate 23 is installed at the top of the pedal 2. The temperature control plate 23 is provided with a number of massage protrusions 231 arranged in an array. A controller 24 for temperature control and adjustment of the temperature control plate 23 is installed at the bottom of one end of the pedal 2.

[0028] It should be noted that the temperature control board 23 described in this embodiment is controlled by the controller 24 to heat or cool, so as to achieve the effect of heating and temperature regulation that keeps the temperature warm in winter and cool in summer.

[0029] Specifically, the temperature control plate 23 installed at the top of the pedal 2 can realize heating or cooling functions under the control of the controller 24. When the user uses it in winter, the controller 24 can activate the heating function of the temperature control plate 23 to raise its temperature and provide a warm environment for the feet. When using it in summer, the cooling function can be activated to lower the temperature of the temperature control plate 23 and bring a cool experience. At the same time, several arrayed massage bumps 231 on the temperature control plate 23 can provide moderate massage stimulation to the soles of the feet when the user places or moves their feet, better relieving leg and foot fatigue caused by prolonged sitting. This makes up for the shortcomings of traditional foot pedals that can only provide support and lack comfort enhancement functions, allowing the foot pedal to bring users a more comprehensive comfort experience in addition to basic support.

[0030] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the two lifting side plates 12 is connected to a connecting shaft 4 between its corresponding connecting ear 21. The connecting ear 21 is rotatably connected to the outside of the corresponding connecting shaft 4. Each of the two transverse slide rods 3 has a collar 33 installed at its bottom end. The two collars 33 are respectively sleeved on the outside of the corresponding connecting shaft 4.

[0031] Specifically, a connecting shaft 4 is inserted between the two lifting side plates 12 and the corresponding connecting ears 21. The connecting ears 21 can rotate around the outside of the connecting shaft 4, thereby enabling the pedal 2 to rotate and adjust its angle around the connecting shaft 4. At the same time, the collar 33 at the bottom of the transverse slide rod 3 is sleeved on the outside of the connecting shaft 4. When the transverse slide rod 3 slides, the collar 33 can be stably connected to the connecting shaft 4, which not only provides stable guiding support for the sliding of the transverse slide rod 3, but also connects the transverse slide rod 3 with the lifting side plates 12, connecting ears 21 and other components through the connecting shaft 4, ensuring that each component works together during the operation of adjusting the angle of the pedal 2, and ensuring the stability of the overall structure and the smoothness of adjustment.

[0032] In one embodiment of this utility model, such as Figures 1-4 As shown, an end plate 41 is fixedly connected to one end of the connecting shaft 4, and a return spring 42 is provided between the end plate 41 and the corresponding connecting lug 21. The return spring 42 is sleeved on the outside of the corresponding connecting shaft 4.

[0033] Specifically, the elastic component is a return spring 42. The end plate 41 at one end of the connecting shaft 4 limits the return spring 42. The return spring 42 is sleeved on the outside of the connecting shaft 4 and its two ends abut against the end plate 41 and the connecting lug 21, respectively. When the pedal 2 rotates around the connecting shaft 4 to adjust the angle, the transverse slide bar 3 drives the connecting shaft 4 to slide outward through the collar 33. At this time, the end plate 41 presses the return spring 42. After the angle adjustment is completed, the return spring 42 pushes back the end plate 41, so that the connecting shaft 4 and the transverse slide bar 3 are automatically returned to their original positions by the pull force, thus completing the automatic locking.

[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, the other end of the connecting shaft 4 is detachably connected to a baffle 43 by bolts, and the baffle 43 covers one side of the corresponding collar 33.

[0035] Specifically, when the angle of pedal 2 needs to be adjusted, the user pushes the foot-operated crossbar 32 to drive the transverse slide bar 3 to slide. The transverse slide bar 3 drives the baffle 43 through the collar 33. The baffle 43 drives the connecting shaft 4 to move outward. At this time, the end plate 41 moves with the connecting shaft 4 and squeezes the return spring 42, so that the return spring 42 accumulates elastic potential energy. At the same time, the limiting block 31 on the transverse slide bar 3 is pulled out from the limiting hole 121, releasing the angle restriction. After the user adjusts the pedal 2 to the appropriate angle, he releases the foot-operated crossbar 32. The return spring 42 releases its elastic potential energy and pushes the end plate 41 back. The end plate 41 drives the connecting shaft 4 to move back. The connecting shaft 4 then pulls the transverse slide bar 3 to reset through the collar 33, so that the limiting block 31 is reinserted into the limiting hole 121 to complete the automatic locking. In addition, the baffle 43 can prevent the collar 33 from falling off from the other end of the connecting shaft 4, ensuring the stability of the fit between the collar 33 and the connecting shaft 4. Furthermore, the bolted baffle 43 is easy to disassemble, facilitating subsequent maintenance or replacement of components such as the connecting shaft 4 and the collar 33.

[0036] In one embodiment of this utility model, such as Figures 1-4 As shown, a U-shaped connecting frame 13 is installed between the two lifting side plates 12. A threaded tube 5 is embedded in the top of the U-shaped support base 1. The threaded tube 5 is rotatably connected to the inner wall of the U-shaped support base 1. A threaded rod 51 is threadedly connected to the inner wall of the threaded tube 5. The threaded rod 51 is fixedly installed at the bottom of the U-shaped connecting frame 13.

[0037] Specifically, the two lifting side plates 12 are connected and fixed through a U-shaped connecting frame 13 to form a stable overall structure. The threaded tube 5 embedded at the top of the U-shaped support base 1 can rotate on its inner wall, and the inner wall of the threaded tube 5 is threadedly connected to the threaded rod 51. The top of the threaded rod 51 is fixedly installed at the bottom of the U-shaped connecting frame 13. When it is necessary to adjust the height of the foot pedal, by rotating the threaded tube 5, the threaded engagement between the threaded tube 5 and the threaded rod 51 is used to move the threaded rod 51 up and down along the axial direction of the threaded tube 5. The movement of the threaded rod 51 will drive the U-shaped connecting frame 13, which is fixedly connected to it, to rise and fall synchronously. This will then drive the two lifting side plates 12 connected to the U-shaped connecting frame 13 and the foot pedal 2 to move up and down as a whole, ultimately achieving precise adjustment of the foot pedal height to suit the needs of users of different heights and furniture of different heights.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] Working principle: When adjusting the height, the threaded tube 5 embedded in the top of the rotating U-shaped support base 1 is rotatable. Through its threaded engagement with the threaded rod 51, the threaded rod 51 moves axially up and down, driving the fixedly connected U-shaped connecting frame 13 and the connected lifting side plate 12 and pedal 2 to rise and fall as a whole, achieving precise height adjustment. When adjusting the angle, the user pushes the foot-operated crossbar 32 outwards with both feet, causing the transverse slide bar 3 to slide along the guide hole 22, disengaging the limiting block 31 from the limiting hole 121. Simultaneously, the transverse slide bar 3 passes through the collar... 33 drives the connecting shaft 4 to move outward, and the end plate 41 squeezes the return spring 42; at this time, step on the pedal 2 to make it rotate around the connecting shaft 4 to a suitable angle, release the foot-push type crossbar 32, the return spring 42 pushes back the end plate 41, driving the connecting shaft 4 and the transverse slide bar 3 to reset, the limit plug 31 is re-inserted into the limit plug hole 121 to complete the locking, the baffle 43 can prevent the collar 33 from falling off, in addition, the controller 24 can control the temperature control plate 23 at the top of the pedal 2 to heat or cool, and the massage protrusions 231 on the temperature control plate 23 can massage the sole of the foot when in use.
