Description

Technical Field

[0001] This utility model relates to a water cup holder, specifically a self-locking water cup holder. Background Technology

[0002] In the daily use of two-wheeled vehicles such as motorcycles and electric bikes, riders often need to carry drinking water. To ensure safety and convenience during travel, cup holders, as an important auxiliary accessory, are widely used on these vehicles. Currently, the basic structure of common motorcycle and electric bike cup holders typically includes a main cup frame, a movable plate, a first fixed arm, and a second fixed arm. One end of both the first and second fixed arms is rotatably engaged with the movable plate, while the other end is rotatably connected to the main cup frame via a reset elastic element. A typical mechanism is an automatic locking cup holder disclosed in application number CN202421536792X.

[0003] In practical use, this type of cup holder relies on the elastic force of the reset elastic element to drive the movable plate to rotate and move closer to the main cup frame, creating a clamping space between the movable plate and the main cup frame to accommodate and secure the cup. When a cup needs to be placed, the driver or passenger can pry the movable plate outward to overcome the elastic force of the reset elastic element and expand the clamping space. After placing the cup, releasing the movable plate allows the reset elastic element to return the movable plate to its original position, thus stably clamping the cup between the movable plate and the main cup frame, meeting basic cup securing requirements.

[0004] However, the existing cup holder structure described above has significant technical flaws in practical applications: when the movable plate is in the lowered position and no cup is placed on it, the elastic element constantly pulls the movable plate towards the main cup holder, causing it to rotate and retract towards the main cup holder under this force, making it unable to stably maintain its lowered position. This not only inconveniences passengers when placing cups—requiring them to readjust the movable plate and overcome the elastic force to secure it each time—but also risks causing the movable plate to wobble during vehicle operation, producing abnormal noises or affecting the normal operation of other components. In extreme cases, it may even interfere with the operation of passengers, posing a safety hazard.

[0005] Therefore, in response to the problem that the movable plate of existing motorcycle and electric vehicle cup holders cannot be positioned when there is no cup and tends to retract on its own, there is an urgent need to develop a cup holder structure that can achieve the function of positioning the movable plate, ensuring that it can be stably kept in the lowered state when needed, while not affecting the normal cup holding function, so as to improve the convenience and safety of use. Utility Model Content

[0006] To address the shortcomings of the prior art, this utility model provides a self-locking water cup holder.

[0007] The technical solution adopted by this utility model is: a self-locking water cup holder, including a main water cup frame, a movable plate, a first fixed arm and a second fixed arm. One end of the first fixed arm is rotatably engaged with the movable plate, and the other end is rotatably connected to the main water cup frame through a self-locking clutch mechanism. The self-locking clutch mechanism includes a self-locking mechanism and a clutch mechanism. The self-locking mechanism is used to position the first fixed arm in the working position, and the clutch mechanism is used to unlock the first fixed arm after positioning.

[0008] One end of the second fixed arm is rotatably engaged with the movable plate, and the other end is rotatably connected to the main frame of the water cup through a reset elastic element.

[0009] The present application further specifies that the self-locking mechanism includes a positioning plate fixedly connected to the first fixed arm and an elastic locking tongue mechanism disposed below the positioning plate, wherein the positioning plate is provided with a positioning groove for positioning and cooperating with the elastic locking tongue mechanism.

[0010] The present application further specifies that: the clutch mechanism includes a clutch housing and an elastic semi-ring; the clutch housing is provided with an upper mounting cavity and a lower mounting cavity; the positioning plate and the elastic semi-ring are installed in the upper mounting cavity; one end of the elastic semi-ring is rotatably connected to a rotating shaft on the bottom wall of the mounting cavity through a rotating hole; and the positioning plate is provided with an abutting step that abuts against one end of the elastic semi-ring.

[0011] The present application further specifies that the elastic locking tongue mechanism includes a locking tongue spring and a locking tongue body, one end of the locking tongue spring abuts against the bottom wall of the lower mounting cavity, and the other end abuts against the locking tongue body, and a slot for the locking tongue body to extend is provided between the upper mounting cavity and the lower mounting cavity.

[0012] The present application further specifies that: the first fixed arm includes a left crank arm, a right crank arm, and a connecting shaft for connecting the left crank arm and the right crank arm; the side of the connecting shaft is provided with at least one limiting cut surface; and the positioning plate is provided with a shaft hole for adapting and connecting with the connecting shaft.

[0013] The present application further specifies that the connecting shaft and the left and right crank arms are fixedly connected by a long pin shaft.

[0014] The present application further specifies that the main frame of the water cup includes a vertical plate and a support plate, and the back of the vertical plate is provided with a positioning groove for the positioning clutch housing.

[0015] The present application further provides that: the inner surfaces of the vertical plate and the movable plate have arc-shaped contact walls, and the two sides of the arc-shaped contact walls are provided with first anti-slip rubber pads at intervals, and the support plate is provided with second anti-slip rubber pads.

[0016] The beneficial effects of this utility model are:

[0017] I. Achieving Mobility by Positioning the Movable Plate: This application utilizes a self-locking mechanism on the first fixed arm to stably position the first fixed arm in the working position when the movable plate is lowered (i.e., unfolded to prepare for placing a water cup), thus keeping the movable plate in the unfolded state and preventing it from retracting automatically under the action of the reset elastic element. When placing a water cup, passengers no longer need to repeatedly bend and fix the movable plate; they can simply place the water cup directly into the clamping space between the movable plate and the main water cup holder. This simplified operation, especially during riding breaks or in one-handed operation scenarios, significantly reduces the difficulty of placing a water cup and greatly improves ease of use.

[0018] II. Balancing Stable Cup Holding and Flexible Unlocking Capabilities: In this bracket, the second fixing arm is always connected to the main cup frame via a reset elastic element. Combined with the reset action of the first fixing arm after the cup is placed (after unlocking and self-locking, the reset elastic element can drive the movable plate to move closer to the main cup frame), it can stably hold cups of different diameters, ensuring that the cup does not tip over or fall off during bumpy rides, meeting the needs of securing conventional cups. Simultaneously, the self-locking clutch mechanism allows for flexible switching between "positioning" and "unlocking": when placing or removing the cup, the movable plate can be flexibly adjusted by unlocking and positioning via the clutch mechanism; when no operation is required, the self-locking mechanism can stably maintain the movable plate's state. This makes it suitable not only for drinking cups used in daily commutes but also for different types of containers such as insulated cups and sports water bottles, making it more widely applicable than existing fixed clamping brackets.

[0019] In addition to the objectives, features and advantages described above, this utility model has other objectives, features and advantages.

[0029] 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.

[0030] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0031] This utility model provides a self-locking water cup holder.

[0032] In this embodiment, refer to Figure 1-7 The self-locking cup holder includes a main cup frame 1, a movable plate 2, a first fixed arm 3, and a second fixed arm 4. One end of the first fixed arm is rotatably engaged with the movable plate, and the other end is rotatably connected to the main cup frame through a self-locking clutch mechanism 30. The self-locking clutch mechanism 30 includes a self-locking mechanism and a clutch mechanism. The self-locking mechanism is used to position the first fixed arm in the working position, and the clutch mechanism is used to unlock the first fixed arm after positioning.

[0033] One end of the second fixed arm 4 is rotatably engaged with the movable plate, and the other end is rotatably connected to the main frame of the water cup through the reset elastic member 5.

[0034] In the above technical solution, the main frame of the water cup provides overall installation support, and the movable plate, together with the first and second fixed arms, constitutes the water cup clamping assembly. One end of the first fixed arm is rotatably engaged with the movable plate, and the other end is rotatably connected to the main frame of the water cup via a self-locking clutch mechanism. When the movable plate is unfolded to a suitable working position for placing the water cup, the self-locking mechanism locks the first fixed arm in that position through mechanical limiting, preventing it from rotating in the opposite direction under the tension of the return elastic element. If it is necessary to retract the movable plate or adjust its position, the clutch mechanism can release the self-locking mechanism's limiting action, allowing the first fixed arm to regain its rotational freedom. One end of the second fixed arm is rotatably engaged with the movable plate, and the other end is rotatably connected to the main frame of the water cup via a return elastic element. Its function is to always provide elastic tension in the direction of the main frame of the water cup, working in conjunction with the first fixed arm to achieve the reset of the movable plate and the clamping of the water cup.

[0035] To address the shortcomings of existing brackets where the movable plate retracts automatically when there is no water cup: through the positioning function of the self-locking mechanism, the movable plate can be stably held in the working position after it is unfolded, without the need for manual fixing by the driver or passenger, thus simplifying the operation process;

[0036] Achieve flexible switching between "positioning and unlocking": The clutch mechanism provides a convenient way to unlock, which does not affect the operational efficiency when the movable plate is retracted, and also ensures the stability of the positioning state;

[0037] It retains the core clamping function of traditional brackets: the reset elastic element design of the second fixed arm can be adapted to different sizes of water cups, ensuring that the water cup will not tip over or fall off during cycling, taking into account both innovation and practicality.

[0038] Specifically: The self-locking mechanism includes a positioning disk 6 fixedly connected to the first fixed arm and an elastic locking tongue mechanism disposed below the positioning disk 6. The positioning disk is provided with a positioning groove 7 for positioning and cooperating with the elastic locking tongue mechanism.

[0039] In this embodiment, the self-locking mechanism consists of a positioning disk fixedly connected to the first fixed arm and an elastic locking tongue mechanism disposed below the positioning disk. The positioning disk rotates synchronously with the first fixed arm. When the first fixed arm drives the movable plate to the working position, the positioning groove on the positioning disk is aligned with the elastic locking tongue mechanism. The elastic locking tongue mechanism is embedded in the positioning groove under its own elastic force. The mechanical engagement between the groove and the tongue achieves the limitation of the positioning disk, thereby preventing the first fixed arm from rotating. If unlocking is required, an external force is applied through the clutch mechanism to disengage the elastic locking tongue mechanism from the positioning groove, thereby releasing the limitation.

[0040] The above-mentioned mechanical interlocking positioning method is not easily affected by environmental factors such as vibration and temperature, and can maintain its positioning status even in bumpy riding scenarios. The precise cooperation between the positioning groove and the elastic locking tongue mechanism ensures that the first fixed arm can be stably locked in the preset working position every time, avoiding the shaking of the movable plate due to positioning deviation.

[0041] Specifically: The clutch mechanism includes a clutch housing 8 and an elastic semi-ring 9. The clutch housing 8 is provided with an upper mounting cavity 10 and a lower mounting cavity 11. The positioning plate and the elastic semi-ring are installed in the upper mounting cavity 10. One end of the elastic semi-ring is rotatably connected to the rotating shaft 13 on the bottom wall of the mounting cavity through a rotating hole 12. The positioning plate is provided with an abutting step 14 that abuts against one end of the elastic semi-ring.

[0042] In this embodiment, the clutch mechanism includes a clutch housing and an elastic half-ring. The clutch housing achieves partitioned installation of each component through upper and lower mounting cavities—the positioning plate and the elastic half-ring are installed in the upper mounting cavity. One end of the elastic half-ring is rotatably connected to the rotating shaft on the bottom wall of the mounting cavity through a rotating hole, allowing it to rotate around the rotating shaft. When unlocking is required, the positioning plate is rotated downwards, and the abutment step on the rotating positioning plate presses against the elastic half-ring, applying external force to the elastic half-ring. This causes it to rotate around the rotating shaft, and the other end of the elastic half-ring presses against the elastic locking tongue mechanism, causing the elastic locking tongue mechanism to disengage from the positioning groove, completing the unlocking process. After the external force is removed, the elastic half-ring resets under its own elastic force, without affecting the next self-locking operation. Only a simple external force is needed to drive the elastic half-ring, eliminating the need for complex operations, making it particularly suitable for one-handed unlocking scenarios while riding.

[0043] Specifically: The elastic locking tongue mechanism includes a locking tongue spring 15 and a locking tongue body 16. One end of the locking tongue spring 15 abuts against the bottom wall of the lower mounting cavity, and the other end abuts against the locking tongue body. A slot 17 for the locking tongue body to extend is provided between the upper mounting cavity and the lower mounting cavity.

[0044] In this embodiment, the elastic latch mechanism consists of a latch spring and a latch body. The lower mounting cavity provides installation space for it. One end of the latch spring abuts against the bottom wall of the lower mounting cavity, and the other end abuts against the latch body, always applying an upward elastic force to the latch body. The slot between the upper and lower mounting cavities provides an extension channel for the latch body, allowing the top of the latch body to pass through the slot and contact the positioning plate in the upper mounting cavity. When the positioning plate rotates until the positioning slot aligns with the slot, the latch body passes through the slot and embeds into the positioning slot under the thrust of the latch spring, achieving self-locking. During unlocking, the latch body is subjected to the thrust of the elastic semi-circular ring, forcing the latch body to compress the latch spring and retract downward into the slot, disengaging from the positioning slot.

[0045] The latch spring continuously provides upward elastic force, ensuring that the latch body always fits tightly against the positioning plate. Once aligned with the positioning groove, it can be quickly inserted to avoid missing locks. Moreover, when the latch body is squeezed, it can be smoothly retracted by compressing the spring without jamming, thus improving the smoothness of the unlocking operation.

[0046] Specifically: the first fixed arm includes a left crank arm 18, a right crank arm 19, and a connecting shaft 20 for connecting the left crank arm 18 and the right crank arm 19. The side of the connecting shaft is provided with at least one limiting cut surface 21, and the positioning plate is provided with a shaft hole 22 for adapting and connecting with the connecting shaft.

[0047] In this embodiment, the first fixed arm consists of a left crank arm, a right crank arm, and a connecting shaft. The connecting shaft connects the left and right crank arms to form a symmetrical support structure. At least one limiting facet is provided on the side of the connecting shaft, and the shaft hole on the positioning plate matches the shape of the connecting shaft (including the corresponding facet). When the positioning plate and the connecting shaft are assembled, the limiting facet and the facet structure of the inner wall of the shaft hole interlock, preventing relative rotation between the positioning plate and the connecting shaft. This ensures that the first fixed arm can synchronously drive the positioning plate to rotate when it rotates, avoiding slippage and subsequent failure of the self-locking mechanism. The shape-matching design of the shaft hole and the connecting shaft allows for circumferential fixation without additional fasteners, simplifying the assembly process and improving production efficiency.

[0048] Specifically: the connecting shaft and the left and right crank arms are fixedly connected by a long pin 23.

[0049] In this embodiment, the connecting shaft is fixedly connected to the left and right crank arms via long pins. The long pins pass through corresponding shaft holes in the connecting shaft and the left and right crank arms, axially fixing all three components and preventing the left and right crank arms from detaching from both ends of the connecting shaft during use. Simultaneously, the rigid connection of the long pins further enhances the overall structural strength of the three components, preventing loosening due to vibration or external forces. Its structure is simple, easy to assemble, and low in cost.

[0050] Specifically: The main frame of the water cup includes a vertical plate 24 and a support plate 25, and the back of the vertical plate 25 is provided with a positioning groove 26 for the positioning clutch housing.

[0051] In this embodiment, the main frame of the water cup consists of a vertical plate and a support plate. The vertical plate provides a vertical mounting reference for components such as the movable plate and the fixed arm. The support plate is used to support the bottom of the water cup and prevent the water cup from sliding down. A positioning groove is provided on the back of the vertical plate. The shape of the positioning groove is adapted to the clutch housing to achieve precise positioning and assembly between the clutch housing and the vertical plate, and to prevent the clutch housing from shifting laterally or longitudinally during use.

[0052] Specifically: the inner surfaces of the vertical plate and the movable plate have arc-shaped contact walls 27, and the two sides of the arc-shaped contact walls 27 are spaced apart with first anti-slip rubber pads 28, and the support plate is provided with a second anti-slip rubber pad 29.

[0053] In this embodiment, the inner surfaces of the vertical plate and the movable plate are designed as arc-shaped contact walls. The arc-shaped structure can conform to the curved shape of the outer wall of the water cup, increasing the contact area between the two and the water cup. First anti-slip rubber pads are distributed at intervals on both sides of the arc-shaped contact wall, and a second anti-slip rubber pad is provided on the support plate. When the water cup is clamped, the arc-shaped contact wall fits against the outer wall of the water cup, and the first anti-slip rubber pad fills the contact gap through its own elastic deformation, increasing the friction. The second anti-slip rubber pad on the support plate supports the water cup from the bottom, preventing the water cup from moving upward or rotating due to bumps.

[0054] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
