Description

Technical Field

[0001] This invention relates to the technical field of photographic accessories, and more specifically to an auxiliary shooting device for backpack shoulder straps. Background Technology

[0002] During outdoor hiking or mountain climbing, more and more users enjoy using action cameras to capture and record the scenery along the way. To free up the hands and facilitate walking, current technology generally uses a backpack shoulder strap quick-release device as a mounting base, on which the action camera is directly installed. The backpack shoulder strap quick-release device is typically fixed at the front of the backpack shoulder strap, allowing for first-person perspective shooting after the action camera is mounted.

[0003] However, the two shoulder straps of a backpack always hang on the user's shoulders, not in the center of the chest. This prevents the quick-release device from being centered, thus causing the action camera to be constantly out of center for shooting, resulting in a consistently off-center shooting angle and affecting the shooting quality. To solve this problem, existing technology provides a quick-release device including a fixed base, a connecting base, and a mounting base. The mounting base allows for camera installation and removal. One end of the connecting base slides to the fixed base, and the other end slides to the mounting base. The mounting base can move smoothly and continuously in a straight line relative to the fixed base, allowing the user to steplessly adjust the camera to a precise center point on their chest.

[0004] However, the aforementioned quick-release device has some problems. For example, for people who are fit and have well-developed pectoral muscles, the pectoral muscles are more prominent, and when pulling the mounting seat, the pectoral muscles will play a certain role in obstructing the movement, making it inconvenient to pull and adjust the position of the mounting seat. Summary of the Invention

[0005] The purpose of this invention is to provide an auxiliary shooting device for backpack shoulder straps to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides an auxiliary shooting device for backpack shoulder straps, comprising a flexible fastening assembly and a quick-release assembly. The flexible fastening assembly includes a fastening part and a mounting part, wherein the fastening part is detachably mounted on the backpack shoulder strap, and the mounting part has a mounting surface. The quick-release assembly includes a fixing seat, a connecting seat, and a mounting seat. The fixing seat is fixed to the mounting surface, and the mounting seat is for camera detachment and installation. The connecting seat includes a slide rail and a connecting plate. One end of the connecting plate is hinged to the fixing seat, and the other end is slidably connected to one end of the slide rail. The other end of the slide rail is hinged to the mounting seat, and the mounting seat can move relative to the fixing seat to adjust its position. Furthermore, one end of the connecting plate is hinged to the fixed base via a second pivot, and the other end of the slide rail is hinged to the mounting base via a first pivot. Both the first pivot and the second pivot are damping shafts. Furthermore, after the connecting plate is slidably stored in the slide rail, the connecting seat can be folded so that the fixing seat, the connecting seat and the mounting seat are stacked in sequence. Furthermore, the fixing base and / or the mounting base are provided with a storage groove, and the connecting base is located in the storage groove. Furthermore, one of the fixed base and the mounting base is provided with an elastic connector, and the other is provided with a snap-fit ​​connector. The elastic connector can snap onto the snap-fit ​​connector to achieve a fixed connection between the fixed base and the mounting base. Furthermore, the elastic connector includes a button, a buckle, and a pressing spring. One end of the pressing spring abuts against the buckle, one end of the button is connected to the buckle, the button is pressed by a hand, and the buckle can be engaged with the connector. Furthermore, the slide rail is provided with an embedding groove, the connecting plate is inserted into the embedding groove and slidably connected to the embedding groove, and the connecting plate can be slidably stored in the embedding groove. Furthermore, the slide rail is provided with an elastic fastener that can extend into the embedded groove, and the connecting plate is provided with at least two sets of stop portions, with the stop portions provided at least at both ends of the connecting plate, and the elastic fastener can be snapped into the stop portions. Furthermore, the gear position is provided with a slot, and the elastic fastener can be snapped into the slot. Furthermore, one end of the slide rail is provided with a mounting cavity, and the elastic fastener is installed in the mounting cavity. The elastic fastener includes a compression spring, a snap-fit ​​block, and a pressing head. One end of the compression spring abuts against the side wall of the mounting cavity, and the other end abuts against the snap-fit ​​block. The snap-fit ​​block can be snapped into the slot. The pressing head is connected to the snap-fit ​​block and drives the snap-fit ​​block to move out of the slot.

[0007] The beneficial effects of this invention are as follows: 1. This application constructs a multi-degree-of-freedom adjustment mechanism through the hinged connection between the connecting plate and the fixed base, the sliding connection between the connecting plate and the slide rail, and the hinged connection between the slide rail and the mounting base. Users can easily and smoothly adjust the position by rotating or folding the camera to avoid protruding body parts such as the pectoral muscles. At the same time, by pulling the connecting plate, the connecting plate slides on the slide rail, further expanding the range of motion of the mounting base, allowing for linear adjustment of the camera's left and right position to align with the center of the chest.

[0008] 2. Both the first and second hinges adopt a damping axis design, which enables the camera to remain stable after being adjusted to a suitable position and angle. It is not limited to center shooting, but can also finely adjust the pitch and tilt angles as needed to obtain a better shooting perspective.

[0009] 3. After the connecting plate slides back into the slide rail, the connecting seat can be folded up so that the fixed seat, connecting seat, and mounting seat are stacked in sequence.

[0016] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] Reference Figures 1 to 3 As an embodiment of the present invention, an auxiliary shooting device for a backpack shoulder strap is provided, including a flexible fastening assembly 10 and a quick-release assembly 20. The flexible fastening assembly 10 includes a fastening part 11 and a mounting part 12. The fastening part 11 is detachably mounted on the backpack shoulder strap, and the mounting part 12 is provided with a mounting surface 13. The quick-release assembly 20 includes a fixing seat 21, a connecting seat 22, and a mounting seat 23. The fixing seat 21 is fixed to the mounting surface 13, and the mounting seat 23 is used for camera disassembly and installation. The connecting seat 22 includes a slide rail 221 and a connecting plate 222. One end of the connecting plate 222 is hinged to the fixing seat 21, and the other end is slidably connected to one end of the slide rail 221. The other end of the slide rail 221 is hinged to the mounting seat 23, and the mounting seat 23 can move relative to the fixing seat 21 to adjust its position.

[0018] In this embodiment, a multi-degree-of-freedom adjustment mechanism is formed by the hinged connection between the connecting plate 222 and the fixed base 21, the sliding connection between the connecting plate 222 and the slide rail 221, and the hinged connection between the slide rail 221 and the mounting base 23. Users can easily and smoothly adjust the camera's position by rotating or folding it to avoid protruding body parts such as the pectoral muscles. Simultaneously, by pulling the connecting plate 222, it slides on the slide rail 221, further expanding the range of motion of the mounting base 23, allowing for linear adjustment of the camera's left and right position to align with the center of the chest.

[0019] Specifically, refer to Figure 1 The fastening part 11 is used to detachably bind and secure the entire device to the backpack shoulder strap. It can specifically employ Velcro straps, elastic bands, or webbing with hooks and loops to accommodate shoulder straps of different sizes and materials. The mounting part 12 is typically a rigid plate, with one side connected to the fastening part 11 and the other side forming a flat mounting surface 13 for mounting the fixing seat 21. The fixing seat 21 is fixed to the mounting surface 13 by screws, clips 252, or adhesive.

[0020] Reference Figures 2 to 4The connecting base 22, as the core adjustment and storage component, is key to achieving multi-degree-of-freedom adjustment and folding functions. The connecting base 22 includes a slide rail 221 and a connecting plate 222. The slide rail 221 has a slot 2211 facing the connecting plate 222's insertion groove 225. One end of the connecting plate 222 is hinged to the fixed base 21 via a second pivot 224, and the other end is inserted into and slidably connected to the insertion groove 225 of the slide rail 221. This allows the connecting plate 222 to slide relative to the slide rail 221 and to be completely or partially stored in the insertion groove 225. The insertion groove 225 not only achieves a stable sliding connection between the connecting plate 222 and the slide rail 221 but also provides the connecting plate 222 with a preliminary storage function when not in use, effectively reducing the overall longitudinal dimension of the device, making it more compact, portable, and easy to store. The other end of the slide rail 221 is hinged to the mounting base 23 via the first pivot 223. Both the first pivot 223 and the second pivot 224 are damping shafts, which enable the camera to remain stable after being adjusted to a suitable position and angle. It is not limited to center shooting, but can also be finely adjusted for pitch and tilt angles as needed to obtain a better shooting angle.

[0021] Furthermore, after the connecting plate 222 is slidably stored in the slide rail 221, the connecting seat 22 can be folded so that the fixing seat 21, the connecting seat 22 and the mounting seat 23 are stacked in sequence.

[0022] Specifically, storage slots 24 are provided on the fixing base 21 and / or mounting base 23 to provide dedicated space for the folded connecting base 22. This design allows all components to be neatly embedded in the storage slots 24 when folded, resulting in a more uniform and integrated appearance. It further reduces the overall thickness and protrusion, prevents components from wobbling after folding, and enhances the product's refined look and portability. When the fixing base 21, connecting base 22, and mounting base 23 are stacked, part or all of the connecting base 22 can be embedded in the storage slots 24, making the overall structure flatter.

[0023] To ensure the stability and safety of shooting, one of the fixed base 21 and the mounting base 23 is provided with an elastic connector 25, and the other is provided with a snap-fit ​​connector 26. The elastic connector 25 can be snapped into the snap-fit ​​connector 26 to achieve a fixed connection between the fixed base 21 and the mounting base 23.

[0024] Reference Figure 5 and Figure 6Specifically, a snap-fit ​​element 26 is provided on the fixed base 21, and an elastic connector 25 is provided on the mounting base 23. The elastic connector 25 includes a button 251, a latch 252, and a pressing spring 253. A mounting groove 233 is provided on one side of the mounting base 23. The latch 252 and the pressing spring 253 are located in the mounting groove 233. One end of the pressing spring 253 abuts against the side wall of the mounting cavity 227, and the other end abuts against the latch 252. The pressing spring 253 causes the latch 252 to tend to pop outward. One end of the button 251 is connected to the latch 252, and the other end extends out of the mounting groove 233. The snap-fit ​​element 26 adopts a slot 226, a hole, or a claw. When the mounting base 23 is folded over the connecting base 22 to overlap with the fixed base 21, or when adjusted to a position that needs to be locked, the latch 252 springs into the snap-fit ​​element 26 on the fixed base 21 under the action of the pressing spring 253, thereby achieving locking. When readjustment is needed, press button 251 to overcome the spring force of spring 253 and retract latch 252, thus releasing the lock. A simple and reliable locking mechanism is provided by the mutually cooperating latching element 26 and elastic connecting element 25 on the fixed base 21 and mounting base 23. When the user is using the camera to take pictures while walking, running, or engaging in other activities, the mounting base 23 can be moved to securely lock it onto the fixed base 21, preventing the mounting base 23 from shifting or loosening due to shaking, thus ensuring the stability and safety of the shooting.

[0025] In other embodiments, the fixed base 21 may be provided with an elastic connector 25, and the mounting base 23 may be provided with a snap-fit ​​connector 26.

[0026] Furthermore, referring to Figure 6 To ensure that the connecting plate 222 slides on the slide rail 221 without detaching from it, at least two sets of stop portions are provided on the connecting plate 222, with stop portions located at least at both ends of the connecting plate 222. An elastic fixing member 27 is provided on the slide rail 221, which can be engaged with the stop portions. By providing the elastic fixing member 26 to cooperate with the at least two sets of stop portions on the connecting plate 222, a clear and reliable position locking mechanism is provided for the sliding of the connecting plate 222. The stop portions near both ends are designed to lock the two typical positions of "fully extended" and "fully retracted," ensuring that the camera position is stable and does not slide during use, and that the connecting plate 222 will not accidentally detach during storage, thus improving the operational certainty and safety of the device.

[0027] Specifically, refer to Figure 7 and Figure 8The slide rail 221 has a mounting cavity 227 at one end, and an elastic fastener 27 is installed in the mounting cavity 227. The elastic fastener 27 includes a compression spring 271, a locking block 272, and a pressing head 273. One end of the compression spring 271 abuts against the side wall of the mounting cavity 227, and the other end abuts against the locking block 272. The stop part has a locking groove 226, and the locking block 272 can be locked into the locking groove 226. The pressing head 273 connects to the locking block 272 and drives the locking block 272 to move out of the locking groove 226. The compression spring 271 provides an automatic locking force, and unlocking can be achieved with a simple pressing action. The operation is intuitive, labor-saving, and efficient. The cooperation between the locking groove 226 and the locking block 272 provides a firm mechanical lock, preventing accidental unlocking due to vibration or movement. The structure is simple, reliable, and durable.

[0028] In this embodiment, the mounting cavity 227 is vertically mounted on the slide rail 221, and one end of the mounting cavity 227 has an opening 2271. The pressing block is installed inside the mounting cavity 227 and one end protrudes from the opening 2271. This layout makes the direction of the pressing operation (usually vertically downward or to the side) more ergonomic, facilitates one-handed operation, and improves the convenience and user experience of quick adjustment in outdoor or sports environments.

[0029] The snap-fit ​​component 26 is positioned near the side of the fixed base 21. When the connecting base 22 rotates and fits against the fixed base 21, a space is left between the snap-fit ​​component 26 and the connecting base 22, facilitating the subsequent snap-fit ​​component 26 and the elastic connecting component 25. The mounting base 23 is provided with a storage groove 24. When the mounting base 23 rotates and fits against the fixed base 21, the connecting base 22 is completely embedded in the storage groove 24. Therefore, in this embodiment, if it is necessary to slide the connecting plate 222 out of the embedded groove 225, the elastic connecting component 25 must be unlocked first, and then the mounting base 23 must be rotated to expose the connecting base 22. Only then can the elastic fixing component 27 be unlocked to allow the connecting plate 222 to slide out of the embedded groove 225.

[0030] In other embodiments, the positions of the elastic fastener 27 and the stop portion can be interchanged. That is, at least two sets of stop portions are provided on the slide rail 221, and the elastic fastener 27 is provided on the connecting plate 222. The elastic fastener 27 can be snapped onto the stop portion.

[0031] Furthermore, the mounting base 23 can be designed as a split type, including a base body 231 and a mounting head 232. The mounting head 232 is used to directly connect the camera and is detachably mounted on the base body 231. By replacing the mounting head 232 with different interface standards, various models of action cameras or compact cameras can be adapted, improving the versatility of the device.

[0032] The auxiliary shooting device for the backpack shoulder strap in this embodiment is used as follows: First, secure the flexible fastening component 10 to any shoulder strap of the user's backpack. Then, mount the camera on the mounting base 23. Adjust the position of the mounting base 23 and the camera by flipping and sliding the connecting base 22 according to the user's body size and backpack status, until the camera lens is positioned at the optimal shooting point directly in front of the user's sternum. This allows for centered first-person perspective shooting, significantly improving the shooting effect.

[0033] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
