Description

Technical Field

[0001] This utility model relates to the field of gaming equipment technology, and in particular to a pedal device and gaming equipment. Background Technology

[0002] Driving simulation game equipment typically includes a steering wheel and pedals, with the pedals being a crucial component for transmitting commands and providing real-time feedback within the game environment. Existing pedal systems consist of pedals and connected drive components. Taking a drive component composed of a lead screw and a drive element as an example, because pedal systems are frequently operated devices, vibrations and load impacts often cause the lead screw and nut to loosen due to relative rotation, leading to force transmission failure and equipment malfunction. Utility Model Content

[0003] Therefore, it is necessary to address the above-mentioned shortcomings by providing a pedal device, comprising: a pedal, a drive assembly, and a locking member. The drive assembly includes a drive member and a lead screw. The drive member is connected to the lead screw and drives the lead screw to move along an axial direction. One end of the locking member is connected to the pedal, and the other end is connected to the lead screw. The end of the lead screw connected to the locking member has a reverse threaded hole. The locking member includes a first through hole and a fixing member with a reverse thread. The fixing member passes through the first through hole and is threadedly connected to the reverse threaded hole. The fixing member is used to fix the locking member to the lead screw.

[0004] Preferably, the pedal device further includes a first fastener, and the locking member has a first clamping part and a second clamping part disposed opposite to each other on the side near the lead screw. At least one of the first clamping part and the second clamping part has a second through hole in the radial direction of the lead screw. The first fastener is used to pass through the second through hole to connect the first clamping part and the second clamping part and to bring the first clamping part and the second clamping part closer to each other to clamp the lead screw.

[0005] Preferably, the first clamping part or the second clamping part has two second through holes, and each of the first fasteners passes through one of the second through holes on the first clamping part or the second clamping part and is connected to the other clamping part.

[0006] Preferably, the first clamping part has a first mounting part on the side near the second clamping part, and the second clamping part has a second mounting part on the side near the first clamping part. The first mounting part and the second mounting part enclose each other to form an installation space. The installation space is used to accommodate one end of the lead screw near the locking member, and the inner diameter of the installation space is larger than the gap between the first clamping part and the second clamping part.

[0007] Preferably, the mounting space has a cavity on the side away from the lead screw, the cavity is located between the first clamping part and the second clamping part, and the cavity communicates with the mounting space. The extending direction of the cavity is the same as the extending direction of the first clamping part and / or the second clamping part, and the radial dimension of the cavity is greater than or equal to the minimum gap between the first clamping part and the second clamping part.

[0008] Preferably, a limiting portion is formed on the side wall of the installation space away from the lead screw, and a positioning surface matching the limiting portion is formed at the end of the lead screw near the locking member. The limiting portion is used to cooperate with the positioning surface to restrict the rotation of the lead screw within the installation space.

[0009] Preferably, the inner walls of the first mounting portion and the second mounting portion are threaded, and one end of the lead screw connected to the locking member is provided with a thread that matches the thread on the inner walls of the first mounting portion and the second mounting portion, and the lead screw is threadedly connected to the locking member.

[0010] Preferably, the lead screw has a threadless section with a diameter smaller than the inner diameter of the lead screw thread at one end near the first through hole. The threadless section is used to form an assembly gap when the lead screw is threadedly connected to the locking member.

[0011] Preferably, the threaded section on the outer surface of the lead screw is provided with a clearance space away from the locking member.

[0012] A gaming device is also provided, including any of the pedal devices described above.

[0013] The aforementioned pedal device and gaming equipment utilize the reverse thread engagement between the fixing component and the reverse threaded hole of the lead screw. The thread direction of the fixing component is opposite to that of the lead screw and its driving component, causing the locking component and the lead screw to move along the axial direction and generate torque resistance. When the lead screw is axially displaced by the driving component, the thread direction of the fixing component is opposite to the direction of the force generated by the movement of the lead screw. This results in a greater load on the pedal and a tighter meshing between the fixing component and the lead screw thread, effectively avoiding the loosening risk that traditional anti-loosening methods are prone to under dynamic scenarios such as repeated stepping and vibration. Even under long-term high-frequency use, it can still maintain a stable and reliable connection effect. Attached Figure Description

Detailed Implementation

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] This utility model discloses a pedal device, such as Figures 1-5As shown, the assembly includes: a pedal 100, a drive assembly 200, and a locking member 300. The drive assembly 200 includes a drive member 210 and a lead screw 220, which is connected to the lead screw 220 and drives the lead screw 220 to move axially. One end of the locking member 300 is connected to the pedal 100, and the other end is connected to the lead screw 220. A reverse threaded hole 220a is provided at the end of the lead screw 220 connected to the locking member 300. A first through hole 300a is provided at a position opposite to the reverse threaded hole 220a on the locking member 300. A fixing member 400 with reverse threads passes through the first through hole 300a and is threadedly connected to the reverse threaded hole 220a at the end of the lead screw 220. The fixing member 400 is used to fix the locking member 300 to the lead screw 220. It should be noted that the reverse thread in the reverse threaded hole 220a at the end of the lead screw 220 and the reverse thread on the fixing member 400 are precisely engaged with each other. This reverse thread engagement method has a thread direction opposite to that of the lead screw 220 and the drive member 210 (i.e., when the lead screw 220 and the drive member 210 are left-handed, the reverse thread is right-handed; when the lead screw 220 and the drive member 210 are right-handed, the reverse thread is left-handed). This can form a torque counteracting force against the movement of the lead screw 220 along the axial direction. When the lead screw 220 is axially displaced by the drive member, the thread direction of the fixing member 400 is opposite to the direction of the force generated by the movement direction of the lead screw 220. This makes the greater the load borne by the pedal 100, the tighter the engagement between the fixing member 440 and the thread of the lead screw 220. This completely avoids the risk of loosening that traditional anti-loosening methods (such as spring washers and snap rings) are prone to in dynamic scenarios such as repeated stepping and vibration. Even under long-term high-frequency use, it can still maintain a stable and reliable connection effect.

[0018] In one embodiment, such as Figures 1-4As shown, the locking member 300 has a first clamping portion 320 and a second clamping portion 330 disposed opposite each other on the side near the lead screw 220. At least one of the first clamping portion 320 and the second clamping portion 330 has a second through hole 300b radially along the lead screw 220. The pedal device also includes a first fastener 310, which is used to connect the first clamping portion 320 and the second clamping portion 330 through the second through hole 300b, and to bring the first clamping portion 320 and the second clamping portion 330 relatively close to each other to clamp the lead screw 220. In one embodiment, a second through hole 300b is formed in the first clamping portion 320, and the first fastener 310 is connected to the second clamping portion 330 through the second through hole 300b. In another embodiment, a second through hole 300b is formed in the second clamping portion 330, and the first fastener 310 is connected to the first clamping portion 320 through the second through hole 300b. By adding a first fastener 310 and the oppositely arranged first clamping part 320 and second clamping part 330, a dual locking mechanism of "reverse thread fixing + radial clamping" is formed: the first fastener 310 passes through the second through hole 300b, bringing the first clamping part 320 and the second clamping part 330 closer together and clamping the lead screw 220, thereby significantly increasing the friction between the first clamping part 320, the second clamping part 330 and the lead screw 220 to fix the lead screw 220, forming a synergy with the fastener 400 with reverse threads. The device functions by providing both axial anti-loosening protection with a reverse thread and radial clamping to eliminate the clearance between the lead screw 220 and the locking element 300, thereby increasing friction and significantly improving connection rigidity and vibration resistance. This effectively reduces the risk of loosening under extreme conditions such as high-frequency stepping and severe vibration. Furthermore, the adjustability of the first fastener 310 allows for adjustment of the clamping force according to actual working conditions, adapting to different load requirements and facilitating tightness calibration during later maintenance, further enhancing the structural reliability and operational flexibility of the pedal device.

[0019] In one embodiment, such as Figures 1-4As shown, the first clamping part 320 has two second through holes 300b, and there are two first fasteners 310. Each first fastener 310 passes through the second through hole 300b on the first clamping part 320 and is connected to the second clamping part 330. In another embodiment, the second clamping part 330 has two second through holes 300b, and there are two first fasteners 310. Each first fastener 310 passes through the second through hole 300b on the second clamping part 330 and is connected to the first clamping part 320. By providing two second through holes 300b in the first clamping part 320 or the second clamping part 330 and cooperating with two first fasteners 310, a dual-point radial clamping structure is formed. Compared with single-point clamping, the clamping force can be distributed more evenly, avoiding deformation of the locking part 300 or the lead screw 220 caused by local stress concentration, and extending the service life of the components. At the same time, dual-point cooperative clamping can further reduce the fit gap with the lead screw 220. Even under high-frequency vibration or heavy load conditions, if a single fastener 310 becomes slightly loose, the other can still maintain effective clamping, significantly improving the overall anti-loosening redundancy and structural stability, and ensuring that the pedal device maintains accurate transmission response and connection reliability during long-term use.

[0020] In one embodiment, such as Figures 1-4 As shown, the first clamping part 320 has a first mounting part 321 on the side near the second clamping part 330, and the second clamping part 330 has a second mounting part 331 on the side near the first clamping part 320. The first mounting part 321 and the second mounting part 331 enclose each other to form a mounting space 300c. The mounting space 300c is used to accommodate one end of the lead screw 220 near the locking member 300. The inner diameter of the mounting space 300c is larger than the gap between the first clamping part 320 and the second clamping part 330. By providing a first mounting part 321 and a second mounting part 331 in the first clamping part 320 and the second clamping part 330 respectively, and enclosing them to form an installation space 300c, and making the inner diameter of the installation space 300c larger than the gap of the clamping parts, the enclosed installation space 300c can form a more closely fitting wrapping contact with the outer peripheral surface of the lead screw 220. This allows the inner walls of the first mounting part 321 and the second mounting part 331 to act evenly on the surface of the lead screw 220, avoiding local stress concentration caused by the small contact area during clamping, reducing the risk of wear on the outer surface of the lead screw 220 or deformation of the clamping parts. At the same time, it can more stably position the lead screw 220 radially, preventing radial offset of the lead screw 220 during axial movement or vibration, and ensuring the accuracy of the transmission response and long-term stability of the pedal device.

[0021] In one embodiment, such as Figures 1-4As shown, based on the previous embodiment, the mounting space 300c has a cavity 300d on the side away from the lead screw 220. The cavity 300d is located between the first clamping part 320 and the second clamping part 330, and the cavity 300d communicates with the mounting space 300c. The extending direction of the cavity 300d is the same as the extending direction of the first clamping part 320 and / or the second clamping part 330. The radial dimension of the cavity 300d is greater than or equal to the minimum gap between the first clamping part 320 and the second clamping part 330. By providing a cavity 300d communicating with the mounting space 300c on the side of the mounting space 300c away from the lead screw 220, the cavity 300d effectively thins the connection between the first clamping part 320, the second clamping part 330 and the locking body, reducing the tensile force required for the relative positional displacement of the first clamping part 320 and the second clamping part 330, thereby reducing the load on the first fastener 310. Furthermore, the cavity 300d provides ample deformation buffer space for the first clamping part 320 and the second clamping part 330. When the first fastener 321 tightens, bringing the first clamping part 320 and the second clamping part 330 closer together, the relative positional displacement of the first clamping part 320 and the second clamping part 330 occurs more smoothly, avoiding local stress concentration caused by rigid constraints and significantly reducing the risk of cracking at the root of the clamping part or at the connection with the mounting part. In one embodiment, the cavity 300d is columnar with an arc-shaped radial cross-section; in another embodiment, its radial cross-section is polygonal.

[0022] In one embodiment, such as Figure 5 As shown, a limiting part is formed on the side wall of the installation space 300c away from the lead screw 220, and a positioning surface 221 matching the limiting part is formed at the end of the lead screw 220 near the locking member 300. The limiting part is used to cooperate with the positioning surface 221 to restrict the rotation of the lead screw 220 within the installation space 300c. By setting a limiting part in the first mounting part 321 and / or the second mounting part 331 to match the positioning surface 221 at the end of the lead screw 220, the rotational freedom of the lead screw 220 within the mounting space 300c can be effectively restricted. On the one hand, this avoids relative rotation between the lead screw 220 and the locking member 300 due to vibration and load fluctuations, preventing loosening of the reverse threaded connection due to rotation. On the other hand, precise rotation limiting ensures transmission stability when the lead screw moves axially, avoiding additional friction or jamming between the inner wall of the mounting space 300c and the lead screw 220 caused by rotational offset, reducing component wear and extending service life. At the same time, the limiting fit between the limiting part and the positioning surface 221 makes the relative position of the lead screw 220 and the locking member 300 more precise, ensuring a stable correspondence between the action of the pedal 100 and the displacement of the lead screw 220, and improving the operating accuracy and response consistency of the pedal device.

[0023] In one embodiment, such as Figures 1-4As shown, the inner walls of the first mounting portion 320 and the second mounting portion 330 are threaded. One end of the lead screw 220 connected to the locking member 300 is provided with a thread that matches the thread on the inner walls of the first mounting portion 320 and the second mounting portion 330. The lead screw 220 is threadedly connected to the locking member. By providing threads on the inner walls of the first mounting portion 321 and the second mounting portion 331 and matching them with the thread on one end of the lead screw 220 connected to the locking member 300, a threaded connection is formed. Through the triple locking of "reverse threaded fixing member + mounting portion threaded engagement + clamping portion radial clamping", the connection reliability is significantly improved. The threaded engagement between the lead screw 220 and the first mounting portion 321 and the second mounting portion 331 allows the lead screw 220 and the locking member 300 to form a deep engagement in the axial direction. The reverse threaded connection between the fixing member 400 and the lead screw 220 forms a bidirectional thread constraint, which greatly enhances the anti-loosening capability. Even under high-frequency vibration or heavy-load conditions, relative loosening can be effectively avoided; at the same time, the threaded engagement increases the contact area between the two, which can distribute the stress load on each component and reduce component fatigue or damage caused by local stress concentration; in addition, the threaded engagement can achieve precise axial positioning of the lead screw 220 and the locking member 300, and with the radial constraint of the clamping part, the relative displacement between the two is further restricted, ensuring that the transmission is more stable when the drive member 210 drives the lead screw 220 to move, and the correspondence between the action of the pedal 100 and the displacement of the lead screw 220 is more accurate, thereby improving the overall operating accuracy and long-term stability of the device.

[0024] In one embodiment, such as Figure 5 As shown, the lead screw 220 has a threadless section 222 with a diameter smaller than the inner diameter of the lead screw 220's thread at one end near the first through hole 300a. The threadless section 222 is used to form an assembly gap when the lead screw 220 is threadedly connected to the locking member 300. By setting a threadless section 222 with a diameter smaller than the inner diameter of the lead screw 220's thread at one end of the lead screw 220 near the first through hole 300a of the locking member 300, on the one hand, the threadless section 222, due to its smaller diameter, can play a guiding role in the initial stage of assembly, helping the lead screw 220 to quickly align with the installation space 300c of the locking member 300, avoiding jamming or sticking due to misalignment during the initial thread engagement, significantly reducing assembly difficulty and improving assembly efficiency in mass production; on the other hand, the assembly gap formed by the threadless section 222 can avoid damage to the thread tooth surface caused by forced tightening, protect the integrity of the thread structure, extend the service life of the component, and further improve the assembly adaptability and long-term stability of the overall device.

[0025] In one embodiment, such as Figure 5As shown, a clearance 223 is provided on the surface of the threaded section of the lead screw 220 away from the locking member 300. During assembly of the lead screw 220 and the locking member 300, unnecessary contact between the lead screw 220 and its components and the locking member 300 may cause distortion of the lead screw 220 or the locking member 300, leading to gaps or localized stress concentration on the contact surface. This can cause the pedal device to wobble or experience localized fatigue during use, significantly affecting its stability and service life. By providing a clearance 223 on the surface of the threaded section of the lead screw 220 away from the locking member 300, the clearance 223 prevents unnecessary contact between the lead screw 220 and its components and the locking member 300 when the lead screw 220 is screwed into the locking member mounting part, thus avoiding distortion and improving the stability and service life of the pedal device. Furthermore, during later maintenance and disassembly, the clearance 223 provides a certain operating space, facilitating the application of force or positioning of the lead screw 220 with tools, reducing disassembly difficulty, and further improving the ease of use and long-term stability of the device.

[0026] In one embodiment, a gaming device includes a pedal device as described in any of the above embodiments.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
