Background Art

[0002] In the fields of various portable electronic device accessories, photographic equipment, and vehicle holders, it is frequently required to quickly attach or remove external devices such as smartphones, auxiliary lighting lamps, and action cameras to or from a base body. Existing connection methods mainly include magnetic adsorption, screwing, and conventional locking structures. The magnetic adsorption type is easy to operate, but it is likely to come off easily when subjected to vibrations or impacts by external forces, lacking connection reliability. The screwing type has a reliable connection, but the procedures for installation and removal are cumbersome and cannot meet the user's need for quick response. In the conventional locking structure, when the user needs to operate multiple unlocking points simultaneously, or the unlocking mechanism is complex and it is often difficult to operate with one hand. Also, when realizing an automatic locking function in an existing locking mechanism, usually, a complex transmission path is required, resulting in a problem that the structure becomes large-sized and the occupied space becomes large. Therefore, in order to solve the above problems, this utility model proposes a pressing lifting mechanism.

Mode for Carrying Out the Invention

[0017] Hereinafter, referring to the accompanying drawings in the embodiments of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of this utility model without creative labor belong to the protection scope of this utility model.

[0018] Embodiment As shown in FIGS. 1-6, a pressing lifting mechanism according to an embodiment of this utility model includes the following. At least one locking member 1 movably attached to the base body, At least one first elastic member 2 connected to the locking member 1, A release member 3 movably attached to the base body and driving the locking member 1 during movement, The locking member 1 contracts in response to external pressure, compresses the first elastic member 2, and automatically resets by the drive of the first elastic member 2 when the external pressure is released.

[0019] This pressing lifting mechanism is composed of three core components: a locking member 1, a first elastic member 2, and a release member 3. The locking member 1 is movably attached to a base body (such as the outer shell, frame, or holder of a bicycle-mounted holder), and is used to form a locking cooperation with an external device (such as an accessory with a locking slot, a smartphone case, the base of an auxiliary lighting lamp, etc.). Please refer to FIGS. 5-6. FIGS. 5-6 show a state in which a smartphone holder for a bicycle is used as the base body, and the locking member 1, the first elastic member 2, and the release member 3 are integrated. The first elastic member 2 is connected to the locking member 1 and always applies a force to maintain or return the locking member 1 to its initial position. Similarly, the release member 3 is movably attached to the base body and forms a transmission relationship with the locking member 1. When the release member 3 moves under an external force, it drives the locking member 1 to generate a corresponding movement, thereby changing the position state of the locking member 1. The entire mechanism realizes the locking and separation from the external device through the movement of the locking member 1.

[0020] <00000​​​​​​​​The locking member 1 is a single integrated component, and its structure is divided into two functional parts: a locking end 11 and a drive end 12. The locking end 11 is the part of the locking member 1 that directly contacts the external device and forms a locking cooperation, and its shape and position determine the locking method and effect with the external device. The drive end 12 is the part of the locking member 1 that receives external driving force and is used for transmission cooperation with the release member 3 or other drive components. When the release member 3 moves, the driving force acts on the drive end 12, causing the entire locking member 1 to move, and consequently the position of the locking end 11 changes, resulting in release.

[0023] By functionally dividing the locking member 1 into a locking end 11 and a drive end 12, a physical separation of the "receiving drive" function and the "performing locking" function is achieved, making the design of the locking member 1 more modular. The shape of the locking end 11 can be individually optimized according to the locking needs of different external devices, and the position and shape of the drive end 12 can also be flexibly adjusted according to the arrangement of the release member 3. Since the two do not interfere with each other, the adaptability and flexibility of the design are greatly improved.

[0024] As shown in Figure 1-6, in some embodiments, the release member 3 is provided with at least one release portion 31, and the release portion 31 cooperates with the drive end portion 12 in a transmission manner.

[0025] The release member 3 is provided with a release section 31 specifically for transmitting driving force. The release section 31 is a specific structure that extends from or is formed from the main body of the release member 3, and forms a transmission cooperation relationship with the drive end 12 on the locking member 1. When the release member 3 moves, the release section 31 also moves with it, and transmits driving force to the locking member 1 through contact or connection with the drive end 12. This transmission cooperation can take various forms depending on the structural design of the release section 31 and the drive end 12, such as direct contact, inclined sliding, and hooking traction.

[0026] The installation of the release section 31 provides a clear interface for power transmission between the release member 3 and the locking member 1. By designing the shape, position, and number of release sections 31, the magnitude, direction, and point of application of the driving force can be precisely controlled, enabling precise control of the movement of the locking member 1. At the same time, since the cooperative relationship between the release section 31 and the drive end 12 is independent of the other parts of the locking member 1, it is easy to individually optimize and adjust the transmission mechanism.

[0027] As shown in Figure 1-6, in some embodiments, one end of the locking member 1 is a rotating end 13 and the other end is a locking end 11, and a fixed shaft 14 is provided passing through the rotating end 13, and the locking member 1 is rotatably installed on the base body via the fixed shaft 14.

[0028] The locking member 1 has an overall U-shape, and the openings of the two locking members 1 face away from each other. One end of the locking member 1 is designed as a pivot end 13, and this end is provided with a structure (e.g., a through hole) for attaching a fixed shaft 14. The fixed shaft 14 is fixed to the base body and passes through the through hole in the pivot end 13, allowing the locking member 1 to rotate freely around the fixed shaft 14. The other end of the locking member 1 is a locking end 11, which moves in an arc as the locking member 1 rotates. This rotational mounting method restricts the movement of the locking member 1 to rotational movement around the fixed shaft 14, and since the motion trajectory is determined, it is easy to control and predict.

[0029] By employing a rotational mounting method, the structure is simple and highly reliable, friction between the moving parts is small, and rotation is smooth. Since the fixed shaft 14 is an independent mounting part, it is easy to process and assemble, and subsequent maintenance and replacement are also easy. The distinction between the rotating end 13 and the locking end 11 clarifies the kinematic characteristics of the locking member 1. That is, the rotating end 13 provides the center of rotation, and the locking end 11 generates the displacement output, making it easy to precisely design the locking position and motion trajectory.

[0030] As shown in Figure 1-6, in some embodiments, the locking end 11 is provided with a guide slope 15 that guides the locking member 1 and displaces the locking end 11 when external pressure comes into contact with it.

[0031] A guide slope 15 is provided at the end of the locking end 11. This guide slope 15 is an inclined plane or curved surface, and when an external device (for example, a smartphone case with a corresponding locking slot) contacts this guide slope 15 and applies pressure, the pressure acts on the slope and is decomposed into a component force perpendicular to the slope and a component force along the slope. The component force along the slope rotates the locking member 1 around the rotating end 13 and displaces the locking end 11 inward. This allows the external device to smoothly move over the locking end 11 and into the locking position. After the external device has moved over the locking end 11, the locking member 1 rotates due to the restoring force of the first elastic member 2, and the locking end 11 is locked into the locking slot of the external device.

[0032] The design of the guide slope 15 enables an automatic locking function that locks simply by pushing it in. The user simply pushes the external device toward the locking end 11, and the guide slope 15 automatically converts the vertical pressure into a force that rotates the locking member 1, eliminating the need for any additional user operation and significantly improving ease of installation and user experience. This slope-based guidance method is simple, efficient, and highly tolerant, allowing for smooth locking even with slight deviations in the mounting angle.

[0033] As shown in Figure 1-6, in some embodiments, the rotating end 13 is provided with a notch 16, a part of the fixed shaft 14 is exposed in the notch 16, the first elastic member 2 is fitted onto the fixed shaft 14, one end of the first elastic member 2 acts on the locking member 1, and the other end acts on the base body.

[0034] A notch 16 is provided at the rotating end 13 of the locking member 1, and a portion of the fixed shaft 14, which is positioned through the rotating end 13, is exposed within this notch 16. The first elastic member 2 (for example, a metallic elastic member such as a torsion spring or coil spring, or a non-metallic elastic member such as rubber) is fitted onto the fixed shaft 14 and positioned within the space secured by the notch 16. One end of the first elastic member 2 is connected to or acts on the locking member 1, and the other end is connected to or abuts against the base body. When the locking member 1 rotates, the first elastic member 2 is twisted or compressed, accumulating elastic energy. When the external force is released, the first elastic member 2 releases energy, causing the locking member 1 to rotate in the reverse direction and reset.

[0035] This design, in which the first elastic member 2 is directly fitted to the fixed shaft 14 and positioned within the notch 16 of the rotating end 13, achieves a high degree of integration between the elastic member and the rotating shaft, resulting in a compact structure with high space utilization and no need for extra installation space. The placement of the notch 16 provides operating space for the first elastic member 2 and avoids motion-interference. This integrated design makes the entire rotating reset module an independent component, facilitating assembly and maintenance.

[0036] As shown in Figure 1-6, in some embodiments, there are two locking members 1, the two locking members 1 are arranged symmetrically, one release portion 31 is provided at each end of the release member 3, and the two release portions 31 cooperate with the drive ends 12 of the two locking members 1.

[0037] The two locking members 1 are attached symmetrically to the base body and are usually arranged symmetrically with respect to the center line. Correspondingly, one release part 31 is provided at each end of the release member 3, and each forms a transmission cooperation with the drive ends 12 of the two locking members 1. When the release member 3 moves, the release parts 31 at both ends simultaneously drive the drive ends 12 of the two locking members 1, causing the two locking members 1 to move synchronously. Due to the symmetrical arrangement, the directions of movement of the two locking members 1 are opposite. For example, they may be pulled inward at the same time or spread outward at the same time.

[0038] By symmetrically arranging the two locking members 1, opposing synchronous locking is achieved, allowing the external device to be clamped or locked from both sides simultaneously. This results in a more balanced and stable locking force, improving connection reliability. The symmetrical structure ensures even load distribution, avoiding the uneven load problem that can occur with single-sided locking. The design, which drives both locking members 1 simultaneously at both ends of the release member 3, guarantees the synchronized movement of both locking members 1, allowing both sides to be released with a single release operation, making operation simple and efficient.

[0039] As shown in Figure 1-6, in some embodiments, the release portion 31 is a release slope provided at the bottom of both ends of the release member 3, the drive end 12 is a transmission arm 121 provided on one side of the locking member 1, and the transmission arm 121 is provided with a transmission slope 122 that cooperates with the release slope.

[0040] When the release member 3 moves, the release slope slides on the transmission slope 122, applying a force to the transmission arm 121 that includes a downward component, thereby driving the locking member 1.

[0041] The release section 31 is designed as a release slope and is located at the bottom of both ends of the release member 3. The drive end 12 is designed as a transmission arm 121 extending from one side of the locking member 1, and the transmission arm 121 is provided with a transmission slope 122 that matches the release slope. When the release member 3 moves horizontally, the release slope slides on the transmission slope 122. Because the two slopes are in contact with each other and their inclination directions are appropriately designed, the horizontal movement of the release slope generates a pressure on the transmission slope 122 in a direction perpendicular to the slope, and this pressure is decomposed into a horizontal component and a vertical component. The vertical component acts on the transmission arm 121, driving the locking member 1 to rotate around the rotation end 13. Through this "slope-slope" cooperative method, the horizontal movement of the release member 3 is converted into a driving force on the locking member 1, including a downward component.

[0042] By employing a transmission system using inclined plane cooperation, the direction of motion can be changed. Specifically, the horizontal movement of the release member 3 is converted into a moment that rotates the locking member 1, resulting in a clever structure and stable transmission. Inclined plane cooperation has good self-adaptability and can automatically correct a certain degree of assembly error. By designing the inclined plane angle, it is possible to precisely control the magnitude and direction of the driving force, and the feel of the release operation and the release force can be adjusted. As shown in Figure 1-6, in some embodiments, the release member 3 is further provided with at least one second elastic member 4, which is used to reset the release member 3 to its initial position.

[0043] To achieve an automatic reset function for the release member 3, this mechanism further provides a second elastic member 4 to the release member 3. The second elastic member 4 can take various forms, such as a metallic elastic member (coil spring, disc spring, mainspring, spring plate, etc.) or a non-metallic or fluid-based elastic member (rubber block, polyurethane elastomer, gas spring, etc.). One end of the second elastic member 4 acts on the release member 3, and the other end acts on the base body. When the release member 3 is moved by an external force, the second elastic member 4 is compressed, stretched, or twisted to accumulate elastic energy. When the external force is released, the second elastic member 4 releases energy and drives the release member 3 to move in the reverse direction, returning it to its initial position.

[0044] The introduction of the second elastic member 4 provides the release member 3 with an automatic reset function. The user no longer needs to manually push the release member 3 back after performing the release operation, making the operation simpler. The automatic reset ensures that the release member 3 always returns to the same initial position after each release operation, preparing it for the next locking operation and ensuring continuity and consistency. The diverse range of elastic member options allows designers to flexibly select members according to space constraints and reset force requirements.

[0045] As shown in Figure 1-6, in some embodiments, the lever 5 is rotatably mounted on the base body, with one end extending to one side of the release member 3 and the other end extending to the outside of the base body, and the rotation of the lever 5 drives the release member 3 to move.

[0046] Lever 5 is rotatably mounted to the base body via a pivot axis in the base body. One end of lever 5 is adjacent to or in contact with one side of the release member 3, and the other end extends outside the base body to form an operating part. When the user operates lever 5 outside the base body, lever 5 rotates around its pivot axis, and the end in contact with the release member 3 moves accordingly. This causes the release member 3 to move linearly, triggering the release action described above. The rotational motion of lever 5 is converted into thrust on the release member 3. Lever 5 itself does not have an independent reset member; when the second elastic member 4 in the release member 3 resets, it pushes the release member 3, and in conjunction with this, lever 5 also resets.

[0047] As shown in Figure 1-6, in some embodiments, an arc-shaped slot 32 is provided on one side of the release member 3, and an arc-shaped projection 51 that fits into the arc-shaped slot 32 is provided on one end of the lever 5. The arc-shaped projection 51 is partially fitted into the arc-shaped slot 32, and the two form a movable connection. When the lever 5 rotates, the arc-shaped projection 51 slides or rotates within the arc-shaped slot 32, driving the release member 3 to move. At the same time, this arc-shaped cooperative structure allows the lever 5 and the release member 3 to automatically adjust their relative angle during the motion process, compensating for deviations caused by differences in the motion trajectory. In addition, because the movement stroke of the release member 3 is short, interference does not occur, ensuring transmission stability and preventing the operation from getting stuck.

[0048] As described above, the coordinated action of the locking member 1, the first elastic member 2, and the release member 3 ensures secure locking and easy release to external devices. The guide slope 15 provided on the locking end 11 automatically rotates the locking member 1 simply by pushing in the external device, allowing for quick attachment by pushing alone, thus eliminating the need for additional operation. The symmetrical arrangement of the two locking members 1, along with the transmission cooperation between the release parts 31 at both ends of the release member 3 and the drive end 12, enables synchronous locking and release, resulting in balanced locking forces and high reliability. The release part 31 slides in cooperation with the transmission slope 122 on the transmission arm 121 via the release slope, resulting in high transmission efficiency. The lever 5 drives the release member 3 through the movable connection between the arc-shaped projection 51 and the arc slot 32, compensating for differences in the motion trajectory and providing a variety of operating methods. The entire mechanism is modularized, making it highly adaptable and easy to operate.

[0049] Finally, it should be explained that the examples described above are merely excellent embodiments of the utility model and do not limit it. While the utility model has been described in detail with reference to the aforementioned embodiments, a person skilled in the art can still modify the inventions described in the embodiments above, or make equivalent substitutions for some of their technical features. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the utility model shall all be covered by the utility model.
