DETAILED DESCRIPTION

[0037] The present invention will be further described below with reference to specific embodiments of the present invention. Figure 1-5 :

[0038] Example 1:

[0039] This embodiment provides a foot-operated door handle, comprising a handle body 1 rotatably connected to a door lock, and is characterized in that it further comprises:

[0040] The control device 2 includes a support base 20 disposed below the handle body 1 and at the bottom of the door panel, a cover plate 21 detachably connected to the support base 20, a pedal assembly 22 disposed on the support base 20, a sliding assembly 23 disposed between the support base 20 and the pedal assembly 22, an elastic return member 24 disposed between the support base 20 and the sliding assembly 23, and a limit assembly 25 detachably disposed on the support base 20 and used to limit the pedal assembly 22;

[0041] The connecting device 3 is provided between the handle body 1 and the pedal assembly 22 .

[0042] The control device 2 controls the operation of the entire foot-driven door handle, including the movement, resetting and position limiting of the pedal assembly 22, to ensure stable operation and accurate operation of the door handle.

[0043] The support base 20 serves as the foundational support structure for the entire control device 2, providing a mounting and securing location for other components. It supports the pedal assembly 22, sliding assembly 23, elastic return member 24, and limit assembly 25, ensuring their relative stability and coordinated function during operation. The support base 20 is typically a block-shaped structure secured to the door panel via fasteners 32, such as screws and rivets. It is typically located on the inside of the door, below the handle body 1, to coordinate with other components and realize the foot-operated door handle function.

[0044] The cover plate 21 protects the internal components of the support base 20, preventing dust and debris from entering and affecting their proper function and service life. It also allows for the entry and exit of the sliding assembly 23. The cover plate 21 is typically a thin plate that matches the shape of the upper surface of the support base 20 and completely covers the upper opening of the support base 20. It can be connected to the support base 20 using screws or snaps, facilitating installation and removal.

[0045] The pedal assembly 22 is the component of the foot-operated door handle system that receives the user's foot force. When the user steps on the pedal, it converts the vertical force into a force that can be used to rotate the handle body 1, thereby opening the door. This force conversion is achieved through the coordinated action of the pedal assembly 22 and other components, such as the connecting device 3.

[0046] The sliding assembly 23 provides precise guidance for the movement of the pedal assembly 22. This guiding function allows the pedal assembly 22 to have a clear directionality when it is subjected to a pedal force, thereby ensuring the accuracy of the entire foot-driven door handle operation.

[0047] After the pedal assembly 22 is stepped on, the elastic return member 24 provides a restoring force, allowing the pedal assembly 22 to automatically return to its initial position, ready for the next operation. It also acts as a buffer and shock absorber during the movement of the pedal assembly 22, reducing impact and wear between components and ensuring continuous and stable door handle operation. Typically, this is a spring or other elastic component. One end of the elastic return member 24 can be connected to the support base 20 via a hook, slot, or other means, while the other end can be connected to the slide base 231 via welding or a hook, ensuring effective force transmission and reset during operation.

[0048] The limit assembly 25 limits the position of the pedal assembly 22, restricting its range of motion and ensuring its stability and accuracy both in its initial position and during movement. This prevents excessive movement or deviation from the normal position of the pedal assembly 22, thereby avoiding damage to the door handle or operational malfunctions caused by uncontrolled movement of the pedal assembly 22 and ensuring proper operation of the door handle.

[0049] The connecting device 3 can transmit the pedal force exerted on the pedal assembly 22 to the handle body 1. When the user steps on the pedal, the force generated by the pedal assembly 22 is converted into a force to rotate the handle body 1 through the connecting device 3, thereby realizing the door opening operation.

[0050] Example 2:

[0051] This embodiment provides a foot-driven door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0052] The sliding assembly 23 includes:

[0053] The slide rail 230 is provided on the support base 20;

[0054] The slide seat 231 is slidably connected to the slide rail 230 , and the slide seat 231 is connected to the pedal assembly 22 .

[0055] The slide rail 230 provides a stable sliding path for the slide seat 231, ensuring that the slide seat 231 can move linearly along a predetermined direction and trajectory, thereby guiding the movement of the pedal assembly 22. The slide rail 230 is typically an elongated structure with a cross-section that generally has a "T"-shaped or "U"-shaped groove structure. It is located on the side of the support seat 20 away from the door panel and is arranged along the length of the support seat 20.

[0056] One end of the slide 231 engages with the slide rail 230, enabling it to slide along the rail. The other end is connected to the pedal assembly 22, transmitting its motion to the slide rail 230 and, through the connecting device 3, to the handle body 1. Simultaneously, the bottom of the slide 231 is connected to one end of the elastic return member 24, working in conjunction with the elastic return member 24 during movement to reset the pedal assembly 22. The slide 231 is generally a block-shaped structure that engages with the slide rail 230, with a connection portion at its other end for the pedal assembly 22.

[0057] Example 3:

[0058] This embodiment provides a foot-driven door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0059] The pedal assembly 22 includes:

[0060] The fixed plate 220 is mounted on the slide 231;

[0061] A foot pedal 221 is connected to the fixing plate 220 and is provided with a first anti-slip member 5;

[0062] The baffle 222 is connected to the foot pedal 221 , and a second anti-slip member 6 is provided on the baffle 222 .

[0063] The fixing plate 220 connects the slide 231 and the foot pedal 221, providing a secure connection and force transmission. It transmits the movement and force of the slide 231 to the foot pedal 221, while also transferring the pedal force applied to the foot pedal 221 to the slide 231, ensuring the coordinated movement of the entire pedal assembly 22. The fixing plate 220 is typically a flat plate, with one side connected to the slide 231 by screws or welding.

[0064] The footrest 221 is the part that the user directly steps on. It receives the user's foot force and transmits it to the fixed plate 220 and the entire pedal assembly 22. A first anti-slip mechanism located above it increases friction between the sole of the foot and the pedal, preventing slipping during pedaling and improving user safety. It is generally a flat plate structure, with one end securely connected to the bottom of the fixed plate 220 by welding or by forming it integrally with the fixed plate 220.

[0065] One end of the baffle 222 is securely connected to the other end of the footrest 221 by welding or by forming it integrally with the footrest 221. The baffle 222 tilts upward at a certain angle. Its primary function is to prevent the foot from sliding beyond the pedal area, providing protection and limiting movement. Furthermore, a second anti-slip mechanism at the other end of the baffle 222 further enhances the anti-slip effect, improving the safety of the entire pedal assembly 22.

[0066] Example 4:

[0067] This embodiment provides a foot-driven door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0068] The first anti-slip member 5 is a plurality of anti-slip protrusions 50 .

[0069] The first anti-slip mechanism increases friction between the sole of the foot and the footplate 221, preventing the foot from slipping when stepping on the footplate 221, thereby ensuring safety and stability when the user operates the foot-operated door handle. In this embodiment, the first anti-slip mechanism comprises anti-slip bumps. The anti-slip bumps can be cylindrical, hemispherical, or other shapes suitable for increasing friction. The anti-slip bumps can be evenly applied to the footplate 221 using glue or snaps.

[0070] Example 5:

[0071] This embodiment provides a foot-driven door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] The second anti-slip member 6 is a plurality of saw-shaped holes 60 .

[0073] The second anti-slip mechanism further enhances the anti-slip effect of the pedal in specific directions or situations, preventing the foot from sliding beyond the pedal range when on the pedal. This provides additional anti-slip protection for the user, especially in some special pedaling actions or unexpected situations. It works in conjunction with the first anti-slip mechanism to improve the anti-slip performance and safety of the entire pedal assembly 22. The second anti-slip mechanism mentioned in this embodiment is a saw-shaped hole provided at equal intervals at the other end of the baffle 222. The saw-shaped hole is serrated, similar to the teeth of a saw. The saw teeth can be right-angled, oblique, or other shapes suitable for increasing friction to better grip the sole and prevent slipping.

[0074] Example 6:

[0075] This embodiment provides a foot-driven door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0076] The connecting device 3 includes:

[0077] The fixed seat 30 is provided on the sliding seat 231;

[0078] A fixing sleeve 31 is sleeved on the handle body 1;

[0079] The connecting member 32 is disposed between the fixing seat 30 and the fixing sleeve 31 .

[0080] The fixing sleeve 31 is tightly fitted on the handle body 1, and plays the role of fixing the connecting device 3 and the handle body 1, ensuring the stability of the connection, and enabling the connecting device 3 to effectively transmit the movement of the pedal assembly 22 to the handle body 1. The fixing sleeve 31 is usually a hollow cylindrical structure. Below the fixing sleeve 31, two symmetrically arranged first fixing plates 220 may be provided for connecting with the connecting member 32. The first fixing plate 220 is used to support and connect the connecting member 32. It is an intermediate component connecting the fixing sleeve 31 and the connecting member 32, and plays the role of transmitting force and fixing the structure. It is generally a flat plate structure, and the plate is provided with holes or other connecting structures for connecting to the connecting plate. It is symmetrically arranged and can be installed below the fixing sleeve 31 by welding or being made integrally with the fixing sleeve 31 to ensure balanced force transmission and structural stability.

[0081] The fixing base 30 can be mounted above the slide 231 using screws, welding, or other methods. It is used to connect to the connector 32, transmitting the movement of the pedal assembly 22 through the connecting device 3. It also provides a mounting location for the connector 32, ensuring a stable connection between the connecting device 3 and the pedal assembly 22. The fixing base 30 can be two second fixing plates 220 fixed parallel to each other on the slide 231. The connector 32 can be fixed between the second fixing plates 220 via an axial connection.

[0082] The connector 32 is provided between the fixed sleeve 31 and the fixed seat 30, and plays the role of connection and force transmission. The connector 32 can be fixed to the fixed sleeve 31 and the fixed seat 30 respectively through an axial connection, realizing the movable connection between the various components of the connecting device 3, so that the movement of the pedal assembly 22 can be smoothly transmitted to the handle body 1, while allowing relative movement within a certain range to adapt to different working conditions and force transmission requirements. The connector 32 is usually a plate-shaped or rod-shaped structure, with a shaft hole at both ends. One end of the connector 32 is connected to the corresponding structure on the fixed sleeve 31 through a shaft, and the other end is connected to the fixed seat 30 in the same way. A clearance fit or transition fit is usually adopted between the connector 32 and the shaft hole to ensure that a certain degree of relative rotation and displacement can be allowed while transmitting force, so as to adapt to different working conditions and force changes during the movement of the pedal assembly 22.

[0084] This embodiment provides a foot-driven door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0085] The handle body 1 is provided with a limiting member 4 threadedly connected to the end of the handle body 1 .

[0086] The stopper 4 limits the fixing sleeve 31 on the handle body 1, ensuring that the fixing sleeve 31 does not separate from the handle body 1 during operation. The stopper 4 can be provided with a threaded rod on the side close to the handle body 1 to cooperate with the internal threaded hole at the end of the handle body 1. The stopper 4 can be cylindrical or block-shaped.

[0087] Example 8:

[0088] This embodiment provides a foot-driven door handle, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0089] The limiting assembly 25 includes:

[0090] The limiting screw 250 is located below the foot pedal 221 in its initial state and is provided on both sides of the support base 20. The support base 20 has limiting holes on both sides for the limiting screw 250 to pass through.

[0091] The limiting nut 251 is provided on the limiting screw 250 .

[0092] The limit screw 250 limits the range of motion of the pedal assembly 22. Its specific position on the support base 20 establishes the upper and lower limits of the vertical movement of the pedal assembly 22, thereby ensuring the stability and accuracy of the pedal assembly 22 in its initial position and during movement. The limit screw 250 is typically an elongated cylindrical structure with a threaded surface. One end may have a head to facilitate tool adjustment, while the other end passes through a limit hole in the support base 20.

[0093] The limiting nut 251 cooperates with the threaded portion on the limiting screw 250 to fix the limiting screw 250 on the support seat 20 to prevent the limiting screw 250 from loosening or displacement during use, thereby ensuring that the limiting function of the limiting assembly 25 is stably implemented.

[0094] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention.
