Description

Technical Field

[0001] This utility model relates to the field of mobile phone mounting bracket technology, specifically to a vertically snap-fit ​​split mounting bracket. Background Technology

[0002] In the field of vehicle equipment installation, split-type mounting brackets are widely used for mounting mobile phones, navigation devices, and other equipment due to their flexible adaptability to vehicle frames and equipment mounting requirements. Currently, most split-type mounting brackets on the market use bolt connections to fix the bracket to the base, but this has significant technical drawbacks: While bolted connections ensure stability, they require tools such as screwdrivers for disassembly and assembly, making the process cumbersome. This is especially true in the confined space of a vehicle, where tool use is limited, resulting in low equipment loading and unloading efficiency and failing to meet users' needs for quick equipment access. Furthermore, long-term vibration can cause bolts to loosen, requiring frequent checks and tightening, leading to high maintenance costs.

[0003] Therefore, there is an urgent need for a vertical snap-fit ​​split-type fixing bracket that can achieve quick assembly and disassembly while being stable and preventing slippage, greatly improving the convenience and reliability of the fixing bracket. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a vertical snap-fit ​​split-type fixing bracket, which can achieve quick assembly and disassembly while being stable and preventing detachment, greatly improving the convenience and reliability of the fixing bracket.

[0005] The basic solution provided by this utility model is: a split-type fixing bracket with vertical snap-fit, including a fixing bracket and a fixing base that can be detachably fixed to the vehicle frame; a connecting component is provided between the fixing bracket and the fixing base; The connecting assembly includes a first connecting part that is detachably connected to the fixed base and a second connecting part that is fixedly connected to the fixed bracket; The first connecting part is provided with a snap-fit ​​component; The second connecting part has a first connecting groove for the snap-fit ​​assembly to extend into. The inner wall of the first connecting groove has a second snap-fit ​​groove. The inner wall of the second snap-fit ​​groove is provided with a guide pressing block. The snap-fit ​​assembly extends into the first connecting groove and is snapped vertically into the second snap-fit ​​groove by the guide pressing block.

[0006] The principle and advantages of this utility model are as follows: In this solution, based on the mechanical cooperation logic of "vertical guiding extrusion + rotation locking", a quick split connection between the fixed bracket and the fixed base is achieved. The specific principle can be broken down as follows: The fixed bracket forms an initial engagement with the snap-fit ​​component of the first connecting part on the fixed base through the first connecting groove of the second connecting part. The snap-fit ​​component extends into the first connecting groove along its axial direction. At this time, the first connecting groove plays a "pre-positioning" role, preventing the snap-fit ​​component from shifting in subsequent operations and providing a precise initial position for vertical snap-fit.

[0007] As the snap-fit ​​assembly continues to extend into the first connecting groove, its outer wall comes into contact with and compresses the "guide extrusion block" on the inner wall of the second snap-fit ​​groove. The guide extrusion block applies radial extrusion force to the snap-fit ​​assembly through its own structure (usually a sloped or curved surface design with a certain degree of elasticity): on the one hand, it guides the snap-fit ​​assembly to move towards the second snap-fit ​​groove along a preset trajectory; on the other hand, it adapts to the shape of the snap-fit ​​assembly through slight deformation, eliminating assembly gaps and laying a sealing / stable foundation for subsequent locking.

[0008] When the snap-fit ​​assembly is guided to the entrance position of the second snap-fit ​​groove by the guide pressing block, the snap-fit ​​assembly rotates around its own axis by rotating the fixed bracket (or fixed base), and finally fully embeds into the second snap-fit ​​groove. At this time, the inner wall of the second snap-fit ​​groove and the snap-fit ​​assembly form a mechanical locking structure "perpendicular to the initial insertion direction", and the snap-fit ​​assembly cannot be dislodged along the axial direction of the first connecting groove. At the same time, the rebound force of the guide pressing block can further press the snap-fit ​​assembly into the second snap-fit ​​groove, achieving a stable connection. To disassemble, simply rotate in the opposite direction to release the lock, and then remove it along the axial direction of the first connecting groove for separation.

[0009] Compared to traditional split-type fixed brackets (such as bolt connections, simple snap-fit ​​connections, etc.), the double-fixing structure: the axial positioning of the first connecting groove + the vertical locking of the second locking groove, forms a double constraint of "axial anti-loosening + radial limiting", which prevents the bracket from loosening in vibrating and shaking environments (such as when the vehicle frame is in motion).

[0010] The guide compression block features a beveled or curved surface. When the locking component is inserted, the compression block guides it along a preset trajectory using compression force, eliminating the need for repeated manual alignment. Even in confined spaces or poor visibility, it can quickly guide the locking component to the second locking slot entrance, significantly reducing alignment difficulty and improving assembly accuracy. After compression, rotation locks the component, creating a mechanical engagement perpendicular to the insertion direction. The locking component is pressed firmly into the slot by the compression block's rebound force, preventing axial dislodgement. Even with frame vibration and bumps, it prevents the bracket from loosening, making it particularly suitable for dynamic scenarios such as vehicle mounting. Its locking reliability far surpasses traditional clips. This achieves both quick assembly and disassembly while ensuring stable anti-dislodgement, greatly improving the convenience and reliability of the fixed bracket.

[0011] Furthermore, the first connecting part includes a first fixed cover and a first open box, the first fixed cover being fastened to the opening of the first open box; the first fixed cover and the fixed base are detachably fixedly connected; support columns are symmetrically arranged on the end of the first fixed cover away from the fixed base, a first spring is sleeved on the support column, a first limiting pin is sleeved on the first spring, the two first limiting pins are fixedly connected by a first connecting rod, and a first mounting groove for installing the snap-fit ​​assembly is opened on the first connecting rod; The snap-fit ​​assembly includes two snap-fit ​​heads, with a first crossbar and a second crossbar respectively provided on the left and right sides of the snap-fit ​​heads. A second spring is sleeved on the second crossbar of the two snap-fit ​​heads and is fixedly connected to the two snap-fit ​​heads respectively. The first open box is provided with a first protrusion hole and a second protrusion hole for the support column and the clip head to protrude; The second connecting part is provided with a limiting hole for the support column to extend into.

[0012] Beneficial effects: In this design, the clamping head is aligned with the first connecting groove of the second connecting part and inserted, with the outer wall of the clamping head contacting the guide compression block on the inner wall of the second clamping groove. As the insertion depth increases, the guide compression block generates radial compression force on the clamping head, forcing the two clamping heads to move inward. At this time, the second crossbar of the clamping head compresses the second spring (stores elastic potential energy), and simultaneously, the clamping head compresses the first connecting rod through the first mounting groove, causing the first connecting rod to move downward.

[0013] When the first connecting rod moves down, it simultaneously pulls the two first limiting pins to slide downward along the axis of the support column. The first limiting pins compress the first spring on the support column, and the support column moves down accordingly until the locking head moves to the entrance position of the second locking slot.

[0014] Rotate the clamping head so that it rotates around its own axis and embeds itself into the second clamping groove. At this time, the squeezing force of the guide squeezing block on the clamping head disappears, the second spring releases its elastic potential energy, and pushes the two clamping heads to open outwards, making them fit tightly against the inner wall of the second clamping groove.

[0015] Simultaneously, the first spring resets, pushing the first limiting pin and the first connecting rod upwards, causing the support column to move upwards until it precisely inserts into the pre-set limiting hole of the second connecting part, completing the "axial limiting". Ultimately, the "radial engagement + axial limiting" forms a double mechanical lock, fixing the first connecting part and the second connecting part.

[0016] After assembly, the clamp head and the second locking groove form a "radial engagement," while the support column and the opening in the second connecting part form an "axial limit." This double mechanical constraint can resist external impacts such as frame vibration and bumps. During disassembly, simply rotating the clamp head in the opposite direction triggers the linkage. The clamp head squeezes and drives the support column downward to disengage from the hole, eliminating the need for forceful prying. The operation requires minimal effort, making it easy even for beginners, thus solving the pain points of traditional fixing structures being "difficult to disassemble and prone to jamming."

[0017] Furthermore, the fixed bracket is a clamping member, which includes a fixed plate fixedly connected to the second connecting part, and a rotating hole for placing the rotating disk is provided at the middle position of the fixed plate; a fixed post is provided at the center position of the rotating disk, and a first gear is sleeved on the fixed post; the fixed disk is fixedly connected to the rotating post. The fixing plate is provided with fixing posts, and the fixing plate is provided with fixing holes for the fixing posts to extend into. It also includes a first clamp and a second clamp arranged on the left and right sides. Both the first clamp and the second clamp include a clamping hook, as well as a rack and a guide limiting block arranged on the top and bottom sides. The rack meshes with the first gear. It also includes a limiting strip set above the fixed plate, the lower end face of the limiting strip is provided with a limiting post, and the guide limiting block is provided with a limiting groove for the limiting post to extend into.

[0018] Beneficial effects: The first gear meshes with the racks of the first and second clamps. When the first gear is rotated, the two clamps can move synchronously in opposite directions, achieving symmetrical clamping. Compared with single-sided adjustable clamping, this ensures that the clamped items (such as mobile phones and devices) are subjected to uniform force.

[0019] The guide limit block and the limit post of the limit strip cooperate with each other. The limit post extends into the limit groove, which can limit the movement direction of the clamp and prevent misalignment or offset when the rack and gear mesh, thus ensuring smooth transmission. At the same time, the limit groove can limit the maximum opening and closing distance of the clamp, prevent the rack from disengaging from the gear, protect the transmission structure, and extend the service life of the clamping parts.

[0020] Furthermore, the first fixing cover is provided with a second mounting groove, and the bottom of the second mounting groove is provided with a first insertion hole for the fixing screw to be inserted. The fixed base has an internal thread that mates with the threaded fixing screw.

[0021] Beneficial effects: The second mounting slot provides a preset installation space for the fixing screw, which can accurately limit the screw position and avoid misalignment during installation; the screw passes through the first insertion hole and engages with the internal thread of the fixing base to form a rigid threaded connection. Compared with connection methods such as snap-fit, it can withstand greater radial and axial forces, effectively preventing the first fixing cover and the fixing base from loosening during frame vibration, and ensuring that the first connection part is fixed and stable as a whole.

[0022] Furthermore, a second spring is fitted onto the fixing screw.

[0023] Beneficial effects: After the screw is tightened, the second spring is in a compressed state, continuously applying axial preload to the first fixing cover, counteracting the tendency of the screw to loosen due to frame vibration, and avoiding the problem of "loose threads" after long-term vibration of traditional threaded connections.

[0024] Furthermore, the card head is provided with a locking tongue type guide.

[0025] Beneficial effects: The locking tongue guide can disperse the contact stress between the chuck and the guide extrusion block, avoiding excessive local force during extrusion that could lead to deformation or wear of the chuck; at the same time, the guide guides the chuck to move smoothly inward, reducing friction between the chuck and the inner wall of the first connecting groove, extending the service life of the chuck, and reducing structural wear.

[0026] Furthermore, a magnetic suction plate is also provided on the fixing plate.

[0027] Beneficial effects: The magnetic plate enables quick positioning, helping users quickly find the snap-fit ​​position. Attached Figure Description
