Description

Technical Field

[0001] This utility model relates to the field of vehicle suction cup technology, and in particular to a suction cup and a vehicle-mounted camera bracket. Background Technology

[0002] A car camera mount is a product used for automotive photography, typically mounted to the vehicle body using a magnetic structure or suction cup. Various interface devices, such as ball joints, magic arm mounts, quarter-mounts, and cold shoe mounts, are then connected to the mount, and the camera is mounted on these devices. Once installed, the camera can take photos while the vehicle is in motion, meeting the needs of special scenarios.

[0003] In related technologies, vehicle-mounted camera mounts are fixed to vehicle surfaces using suction cups, avoiding damage to the vehicle's surface. However, when these suction cup products are connected to other equipment, the concentrated weight of the equipment can cause excessive localized pressure at the connection points, leading to stress concentration. This reduces the strength of the connection frame and decreases the durability of the suction cup product. Utility Model Content

The valve body extends into the connecting frame, and the inner cavity of the valve body communicates with the inner cavity of the push tube. A pressing rod is sleeved inside the push tube, and a portion of the pressing rod extends into the inner cavity of the valve body. The push rod is sleeved on the outside of the pressing rod and extends into the inner cavity of the push tube.

[0013] In one embodiment, the end of the pressing rod away from the push rod is provided with a pushing part, an airtight component is connected between the pressing rod and the pushing part, an elastic component is sleeved on the outer periphery of the pressing rod, and the pushing part can reciprocate along the inner cavity of the valve body under the push of the pressing rod.

[0036] This utility model proposes a suction cup 1000.

[0037] Please see Figures 1 to 4 In one embodiment of the present invention, the suction cup includes a suction cup body 1, a connecting frame 2, and an air extraction structure 3. The suction cup body 1 is connected to the connecting frame 2. A connecting portion 21 is formed on the surface of the connecting frame 2 away from the suction cup body 1. The connecting portion 21 has multiple Arri positioning holes 22 and threaded holes 23 for connecting equipment. The air extraction structure 3 is located between the suction cup body 1 and the connecting frame 2. A portion of the air extraction structure 3 extends into the connecting frame 2, and the inner cavity of the air extraction structure 3 communicates with the inner cavity of the suction cup body 1.

[0038] In this embodiment, the suction cup is used in an automotive photography scene with a vehicle-mounted photography bracket 2100. The suction cup body 1 is used for direct contact with the car surface; the connecting bracket 2 is used to increase the usage methods of the suction cup and connect it to different equipment; the vacuum structure 3 is used to extract the air from inside the suction cup body 1 to create a vacuum environment. It can be understood that the connecting part 21, i.e., the end surface of the connecting bracket 2 away from the suction cup body 1, is the connection surface for connecting with equipment. The Arri positioning hole 22 is used for precise alignment, ensuring that the equipment maintains accurate orientation and accuracy when connected to the suction cup. The threaded hole 23 can be used to fix the equipment with bolts, screws, etc., enhancing the mechanical strength and firmness of the connection. The combination of these two allows for multi-point fixation, ensuring that the connection between the suction cup and the equipment does not loosen; at the same time, multiple connection points can evenly distribute the load from the suction cup, reducing the problem of local stress concentration.

[0039] The technical solution of this utility model utilizes the air extraction structure 3 to form a seal between the suction cup body 1 and the car surface, increasing the suction force by extracting air and ensuring that the suction cup is firmly fixed to the car surface. Furthermore, by providing multiple Arri positioning holes 22 and threaded holes 23 at the connection part, the connection between the suction cup and other equipment is ensured to be more stable, reducing loosening or detachment during use. The multiple positioning holes 22 and threaded holes 23 distribute the weight of the equipment, reducing localized pressure, and the combination of the air extraction structure 3 and the connecting frame 2 enhances the strength of the connecting frame, effectively reducing stress concentration and its impact on the durability of the suction cup.

[0040] In one embodiment of the present invention, the connecting part 21 has a central section 211 and an edge section 212 that are integrally formed. The edge section 212 is arranged around the central section 211 and is connected to the suction cup body 1. The height of the central section 211 is higher than the height of the edge section 212. The central section 211 is provided with a plurality of Arri positioning holes 22 and threaded holes 23.

[0041] Combination Figure 1 and Figure 2In this embodiment, the connecting portion gradually tapers from its edge towards its center. The center of the connecting portion 21 protrudes beyond its surrounding edges, and the connection between the center and the surrounding edges forms an arc-shaped transition. A marking area can be placed at the edge of the protruding portion and the edge portion, where a nameplate or similar item can be placed. The higher design of the central section 211 allows it to better bear the load of the suction cup connection to the equipment, providing stronger support. The design of the edge section 212 surrounding the central section 211 enhances the stability and sealing of the connection, especially under vibration and external impact, preventing excessive stress or deformation of the central section 211. By setting the end surface of the connecting frame 2 away from the suction cup body 1 to have its center protruding beyond the edge of the surface, the stress load is more evenly distributed when the connecting portion 21 is connected to the equipment, reducing stress concentration points. Simultaneously, the protruding portion increases the rigidity of the suction cup connecting frame 2, improving its bending resistance and maintaining structural integrity. The above-described configuration increases the stability of the suction cup connector 2 and reduces deformation or damage caused by external forces. This configuration also enhances the compressive and tensile strength of the connector 21.

[0042] In one embodiment of this utility model, each Arri positioning hole 22 is arranged around the threaded hole 23.

[0043] Combination Figure 2 In this embodiment, it is understood that by surrounding the threaded hole 23 with the Arry positioning hole 22, the force can be evenly distributed across multiple points, avoiding localized stress concentration. Simultaneously, the Arry positioning hole 22 can prevent bolts or nuts from loosening, providing an anti-loosening effect, especially under vibration or high-load environments, increasing the connection's robustness; it also serves as an auxiliary positioning element, evenly distributing pressure from the bolts during connection, reducing component damage or deformation caused by uneven stress, thereby enhancing the structural strength and compressive resistance of the entire connection 21. Furthermore, the shape of the aforementioned arrangement also possesses a certain degree of symmetry and aesthetic appeal.

[0044] In one embodiment of this utility model, the suction cup body 1 has a cavity, the cavity contains a connector 11, the connector 11 has a first through hole 11a, the connecting frame 2 has a locking member, the connecting frame 2 has a second through hole 24 corresponding to the first through hole 11a, and the locking member passes through the first through hole 11a and is fixed to the second through hole 24.

[0045] In this embodiment, the cavity is used to accommodate the connector 11, housing it inside the suction cup body, thus improving the overall compactness of the device. The connector 11 is in the form of a metal block, preferably ring-shaped with a hollowed-out center. Figure 4One end of the connector 11 protrudes to form a sleeve-shaped protrusion. A first through hole 11a is formed at the end of the sleeve-shaped protrusion near the connecting frame 2. A second through hole 24 is correspondingly formed on the connecting frame 2 at the position of the sleeve-shaped protrusion. A locking element passes through the first through hole 11a and the second through hole 24 to lock and fix the connector. Accordingly, the locking element here is a bolt, and the first through hole 11a and the second through hole 24 are threaded holes 23; alternatively, the locking element here can be a spring pin, and the first through hole 11a and the second through hole 24 are slotted holes. It can be understood that by fixing the connector through the first through hole 11a and the second through hole 24, the fastening force between the suction cup body 1 and the connecting frame 2 is ensured, preventing loosening or unstable connection. This arrangement improves the stability and safety of the suction cup, while also making the suction cup design more compact.

[0046] In one embodiment of this utility model, the air extraction structure 3 includes a valve body 31, a push tube 32, and a push rod 33. The valve body 31 extends into the connecting frame 2, and the inner cavity of the valve body 31 communicates with the inner cavity of the push tube 32. A pressing rod 321 is sleeved inside the push tube 32, and part of the pressing rod 321 extends into the inner cavity of the valve body 31. The push rod 33 is sleeved on the outside of the pressing rod 321 and extends into the inner cavity of the push tube 32.

[0047] In this embodiment, it is understood that the push rod 33 can extend into the inner cavity of the push tube 32 and abut against the pressing rod 321. Pressing the push rod 33 drives the pressing rod 321 to move along the inner cavity of the valve body 31 from the end near the push rod 33 to the end away from the push rod 33, thereby compressing the inner cavity of the valve body 31 to achieve the function of suction. Furthermore, in order to prevent the suction cup from falling off due to changes in air pressure, the push rod 33 is provided with a warning scale. When the external air pressure is much greater than the internal air pressure of the valve body 31, the warning scale is hidden in the push tube 32. When the internal air pressure of the valve body 31 increases, the push rod 33 moves away from the valve body 31 under the action of the internal air pressure, and the warning scale moves outward accordingly. When the push rod 33 is completely moved outside the push tube 32, the warning scale is fully displayed on the outside. At this time, the user can pay attention to the installation status of the suction cup through the warning scale to provide a monitoring function.

[0048] In one embodiment of the present invention, the end of the pressing rod 321 away from the push rod 33 is provided with a pushing part 322, and an airtight member 323 is connected between the pressing rod 321 and the pushing part 322. An elastic member 324 is sleeved on the outer periphery of the pressing rod, and the pushing part 322 can move back and forth along the inner cavity of the valve body 31 under the push of the pressing rod 321.

[0049] In this embodiment, to effectively prevent gas leakage and ensure the airtightness of the pumping process, an airtight component 323 is provided to prevent gas exchange between the inside and outside of the system during the reciprocating motion of the pressing rod 321, thus ensuring that the negative pressure within the system remains stable. Accordingly, the airtight component 323 can be made of rubber, silicone rubber, etc., preferably a silicone plug, and is fitted between the pressing rod 321 and the pressing part. The elastic component 324 is preferably a coil spring, which provides elastic restoring force and a cushioning effect. This arrangement effectively ensures the airtightness during the pumping process and prevents gas leakage; simultaneously, the elastic component 324 provides elastic restoring force, allowing the pressing part 322 to automatically reset after operation, ensuring the continuity and stability of the operation.

[0050] In one embodiment of this utility model, the suction cup body 1 has a cavity, and the cavity contains a connector 11. The connector 11 has a third through hole 11b. The valve body 31 has an exhaust nozzle 311 that communicates with the inner cavity of the valve body 31. The exhaust nozzle 311 passes through the suction cup body 1 and communicates with the third through hole 11b. Alternatively, the valve body 31 has a valve core 312 that is located near the exhaust nozzle 311 and communicates with the inner cavity of the valve body 31.

[0051] In this embodiment, the exhaust nozzle 311 is used to discharge gas. The valve core 312 is used to regulate the flow of air and has a one-way ventilation function to ensure that the gas discharged from the exhaust nozzle 311 does not flow back from the exhaust nozzle 311. Accordingly, the exhaust nozzle 311 is provided on the valve body 31 by means of threaded connection or other means, and the valve core 312 and the valve body 31 are integrally formed. It can be understood that when the suction cup needs to be disassembled, the outer peripheral wall of the suction cup body 1 is provided with a disassembly point, which is connected to the inner cavity of the suction cup body 1. When the disassembly point is opened, the internal air pressure of the valve core 312 is connected to the external air pressure, and the air pressure difference tends to be balanced, so that the suction cup can be disassembled. Further, when the user installs, he places the suction cup on the mounting surface of the car and pushes the push rod 33. The push rod 33 pushes the pressing rod 321, thereby the pressing part of the pressing rod 321 compresses the inner cavity of the valve body 31. At this point, the air pressure between the suction cup body 1 and the car mounting surface increases, opening valve core 312 and releasing gas from exhaust nozzle 311. This reduces the air pressure between the suction cup body 1 and the car mounting surface. Because the air pressure between the suction cup body 1 and the car mounting surface is lower than the external atmospheric pressure, the suction cup presses firmly against the mounting surface under negative pressure, thus completing the suction cup installation process. After installation, equipment can be connected via connecting bracket 2 to fulfill photography and other needs.

[0052] This utility model also proposes a vehicle-mounted camera bracket 2000, which includes an adapter and the aforementioned suction cup. The specific structure of the suction cup is as described in the above embodiments. Since this vehicle-mounted camera bracket 2000 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The adapter is connected to the suction cup, and the adapter is provided with a connection part for mounting the camera device.

[0053] In this embodiment, the connection method between the adapter and the suction cup includes, but is not limited to, bolt connection, snap-fit, etc., and is not limited here. Figure 5 Accordingly, to further enhance stability during use, multiple suction cups are incorporated. This design improves connection strength and makes assembly and disassembly more convenient, adapting to different types of adapters. It is understood that the adapter has an interface at the end furthest from the suction cup. Adapter types include, but are not limited to, magic wrist mounts and ball heads; adapters can also be designed as fixed-length or telescopic tubes, without limitation. Interface types include, but are not limited to, action camera (GoPro) connectors, quarter-screw connectors, or cold shoe connectors, allowing users to choose according to their needs. Adapters can also be in the form of sliders, used to clamp and secure equipment to a slider holder. The slider connects to the suction cup via threads. Correspondingly, the slider has clamping grooves for securing equipment to it via clamping.

[0054] In one embodiment of this utility model, the vehicle-mounted camera bracket includes three suction cups as described above. The adapter includes a first bracket 2100, a second bracket 2200, and a connecting arm 2300. The connecting arm 2300 connects the first bracket 2100 and the second bracket 2200. Two of the suction cups are connected to the two ends of the first bracket 2100, and the other suction cup is rotatably connected to the end of the second bracket 2200. The three suction cups are triangularly distributed along the plane of each suction cup.

[0055] In this embodiment, combined with Figure 6 The first bracket 2100 and the second bracket 2200 cooperate to provide additional support and stability for the entire vehicle-mounted camera bracket. Here, the bracket takes the form of a connecting rod. The number of suction cups includes, but is not limited to, three. The three suction cups are arranged in a triangle to provide good stability and reduce displacement or shaking of the camera bracket caused by vibration or impact during vehicle movement. Accordingly, the connection methods between the suction cups and the first bracket 2100 and the second bracket 2200 include, but are not limited to, threaded connections, snap-fit ​​connections, etc. It can be understood that one end of the connecting arm 2300 is slidably fitted onto the first bracket 2100 and locked in place by a locking device, while the other end of the connecting arm 2300 is connected to the second bracket 2200 by a screw connection or other means. Figure 7The connecting arm 2300 is used to adjust the rotation angle of the second bracket 2200. The connecting arm 2300 includes a detachably connected first clamping arm 2301 and second clamping arm 2302, a locking screw 2303, and a locking knob 2304. The first clamping arm 2301 and second clamping arm 2302 can be detachably connected by bolts, clips, or other means. Each end of one corresponding side of the first clamping arm 2301 and second clamping arm 2302 has an arc-shaped groove 2305. A universal ball joint 2306 is installed within the arc-shaped groove 2305. Each universal ball joint 2306 contacts the inner wall of the arc-shaped groove 2305 and is rotatably connected to the arc-shaped groove 2305; this rotatable connection is a hinged connection. Each universal ball joint 2306 is connected to the first bracket 2100 and the second bracket 2200 respectively via a connecting seat 2307; this connection is also a hinged connection. The first clamping arm 2301 and the second clamping arm 2302 have through holes. A locking screw 2303 passes through these through holes and is screwed onto a locking knob 2304, which in turn abuts against the periphery of the through hole. The knob drives the locking screw 2303 to rotate, causing the first clamping arm 2301 and the second clamping arm 2302 to clamp or release each universal joint 2306, thereby adjusting the orientation and elevation angle of the first bracket 2100 and consequently, the spatial position of the camera. Furthermore, due to the presence of the universal joint 2306 in the connecting arm 2300, the universal joint 2306 provides almost omnidirectional freedom of movement, including rotation and tilt, allowing the orientation and elevation angle of the first bracket 2100 to be adjusted arbitrarily. This configuration improves the convenience of the vehicle-mounted camera bracket.

[0056] In one embodiment of this utility model, the second support 2200 is made of an elastic sheet.

[0057] In this embodiment, it is understood that the elastic sheet here includes, but is not limited to, elastic steel sheets, patch plastic sheets, and other materials with elastic deformation capabilities, so as to achieve the technical effect of preventing excessive vibration from affecting the camera and other components during the shooting process.

[0058] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
