Description

Technical Field

[0001] This utility model relates to the field of motorcycle mobile phone holder technology, specifically a ratchet-type quick-release motorcycle mobile phone holder structure. Background Technology

[0002] Motorcycle phone holders are essential accessories for riders to secure their phones and enable navigation and communication functions. Currently, most motorcycle phone holders on the market use a spring-loaded clamping structure, where the spring's elastic restoring force drives the clamps to hold and secure the phone.

[0003] While this structure is simple to build and easy to operate, it presents significant safety hazards in actual use. Specifically, when a motorcycle travels at high speed over potholes, speed bumps, or continuous bumpy sections, the motorcycle experiences a severe longitudinal impact. Under this impact, the phone, due to its own mass, generates a significant downward inertial force. When this inertial force exceeds the clamping force provided by the internal springs of the phone holder, the grippers are forced to open outwards, causing the phone to detach from the holder and fall, easily damaging the phone or even causing a riding accident.

[0004] Therefore, there is an urgent need for a motorcycle phone holder that can effectively resist inertial impacts and prevent the clamping mechanism from opening accidentally under complex road conditions, so as to improve the reliability and safety of phone fixation during riding. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a ratchet-type quick-release motorcycle mobile phone holder structure.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a ratchet-type quick-release motorcycle phone holder structure, comprising an upper shell, a lower shell, a clamping mechanism, a stretching mechanism, and a limiting mechanism. The clamping mechanism includes a second clamping block and a first clamping block linked to the second clamping block. The second clamping block can move along a preset direction, and the first clamping block can be simultaneously opened or clamped by the stretching mechanism and an adjusting plate. The stretching mechanism is used to provide a reset force to the second clamping block, so that the second clamping block resets in the clamping direction after the external force is released. The limiting mechanism includes a toothed structure disposed on the second clamping block and a pawl disposed on the shell. The pawl can switch between two working positions. In the first working position, the first ratchet surface engages with the tooth structure; in the second working position, the second ratchet surface engages with the tooth structure, allowing the second clamping block to move along the first direction but restricting its movement along the second direction in one working position, and allowing its movement along the second direction but restricting its movement along the first direction in another working position. Since the first clamping block and the second clamping block are linked, when the limiting mechanism restricts the movement of the second clamping block along the corresponding direction, the adjusting plate is synchronously restricted, thereby restricting the movement of the first clamping block, thus realizing the linkage locking of the clamping mechanism. The tooth structure is set in the limiting groove formed in the second clamping block, and multiple teeth are arranged along the movement direction of the second clamping block, with each tooth corresponding to a different clamping position of the second clamping block.

[0009] Furthermore, the limiting mechanism also includes a connecting rod, a movable rod, a lever, and a pin. The connecting rod is rotatably mounted inside the housing via a fixed column. The pawl is fixedly connected to one end of the connecting rod and rotates around the fixed column with the connecting rod, selectively engaging with different teeth as the connecting rod rotates. The other end of the connecting rod is movably connected to the movable rod via a pin. A lever is provided at the bottom of the connecting rod. The lever extends outside the lower housing and is located in a movable groove opened in the lower housing. Moving the lever can drive the connecting rod to rotate around the fixed column, allowing the pawl to switch between different working positions.

[0010] Furthermore, the pawl has a first pawl surface and a second pawl surface that are arranged opposite to each other. The first pawl surface and the second pawl surface are located on opposite sides of each other and form an angle between them. The first pawl surface is used to form a one-way locking in a first direction, and the second pawl surface is used to form a one-way locking in a second direction opposite to the first direction.

[0011] Furthermore, a pressure cover plate is fixed inside the lower housing by a fixing bolt. A pressure groove is formed on the opposite side of the pressure cover plate and the lower housing. A pressure spring is installed in the pressure groove. The other end of the movable rod is set in the pressure groove by a pin. The pressure spring continuously applies an elastic force to the movable rod in the direction of the connecting rod, keeping the connecting rod rotating toward the tooth structure, so that the pawl always remains engaged with the tooth structure.

[0012] Furthermore, the lower housing is provided with a first sliding groove and a second sliding groove. The first clamping block is slidably disposed in the first sliding groove, and the second clamping block is slidably disposed in the second sliding groove. The first sliding groove is used to guide and limit the first clamping block. A limiting block is fixed inside the lower housing by a fixing bolt. The second sliding groove cooperates with the limiting block to guide and limit the second clamping block, so as to limit the second clamping block to reciprocate only in a preset direction.

[0013] Furthermore, the first clamping block is slidably connected to the guide groove on the adjusting plate via a guide block. When the second clamping block moves, it drives the adjusting plate to move synchronously, so that the guide block slides along the guide groove and drives the two first clamping blocks to move closer or further away synchronously.

[0014] Furthermore, a guide plate is fixed inside the upper housing, and the adjusting plate is slidably coupled with the guide plate. The guide plate is used to limit the sway of the adjusting plate and to move the adjusting plate along the direction of movement of the second clamping block.

[0015] Furthermore, the tensioning mechanism includes a connecting column, a horizontal plate, a positioning block, and a tension spring. The horizontal plate is disposed between the second clamping block and the adjusting plate. Positioning blocks are fixed at both ends of the horizontal plate and are adapted to the positioning holes of the second clamping block and the adjusting plate. A spring groove is provided in the adjusting plate, and the tension spring is located in the spring groove. One end of the tension spring is fixedly connected to the connecting column disposed in the middle of the horizontal plate, and the other end is fixed to the lower housing through a fixing bolt, so as to drive the second clamping block, the horizontal plate, and the adjusting plate to reset synchronously after the second clamping block is released.

[0016] Furthermore, the lower housing surface is provided with a locking block that matches the locking groove provided on the bottom surface of the upper housing, the upper housing surface is provided with a wireless charging area, the upper housing and the lower housing are connected by a fixing bolt, and the bottom end of the lower housing is fixed with a connecting seat.

[0017] Furthermore, anti-slip pads are provided on the first and second clamping blocks. The first clamping block is located on the left and right sides of the phone, and the second clamping block is located on the bottom of the phone. The first and second clamping blocks together form a three-point clamping structure.

[0018] (III) Beneficial Effects:

[0019] Compared with the prior art, this application has the following beneficial effects:

[0020] I. This utility model fundamentally prevents inertial loosening by using a bidirectional selectable unidirectional mechanical locking mechanism. The limiting mechanism engages with the unidirectional ratchet teeth in the upper limit groove of the second clamping block through a pawl. In the first working position, the second clamping block is allowed to move upward but its downward movement is restricted. When the motorcycle passes over a pothole and generates a downward inertial impact force on the second clamping block, this impact force is directly borne by the engagement of the pawl and teeth and transmitted to the housing. The second clamping block cannot move downward, thus completely avoiding the problem of the clamping mechanism accidentally opening and the mobile phone falling due to the impact force overcoming the spring force.

[0021] Second, in this utility model, the second clamping block cooperates with the guide block on the first clamping block through the guide groove on the adjusting plate, realizing a single action to drive the two first clamping blocks to open or clamp synchronously, forming a three-point linkage clamping. The movement constraint of the limiting mechanism on the second clamping block is synchronously converted into locking of all the first clamping blocks through the transmission chain of the adjusting plate, guide groove and guide block, realizing the full linkage mechanical locking of the entire clamping mechanism. The structure is compact and the transmission is reliable. Attached Figure Description

[0035] 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.

[0036] like Figure 1-12 As shown, this embodiment provides a ratchet-type quick-release motorcycle phone holder structure, including an upper housing 1 and a lower housing 2. The upper housing 1 covers the lower housing 2, and the upper housing 1 and lower housing 2 are fixedly connected, forming an installation cavity for mounting a clamping mechanism, a tensioning mechanism 12, and a limiting mechanism 15. Preferably, the upper housing 1 and the lower housing 2 are engaged with each other by a locking block 21 on the lower housing 2 and a locking groove 23 on the upper housing 1, and further locked by a fixing bolt 6, so as to achieve quick assembly and disassembly and ensure reliable connection.

[0037] The upper casing 1 has a wireless charging area 3 on its front side. This area supports the phone and charges phones that support wireless charging. First clamping blocks 4 are located on the left and right sides of the wireless charging area 3, and a second clamping block 5 is located on the lower side. The two first clamping blocks 4 hold the left and right sides of the phone respectively, and the second clamping blocks 5 support and hold the bottom of the phone. The first clamping blocks 4 and second clamping blocks 5 together form a three-point clamping structure. Anti-slip pads 7 are provided on the side of each of the first clamping blocks 4 and second clamping blocks 5 that contacts the phone to improve clamping friction and reduce relative slippage of the phone during cycling. Preferably, the anti-slip pads 7 are made of silicone or rubber.

[0038] In order to achieve the linkage clamping of the first clamping block 4 and the second clamping block 5, this embodiment is provided with a clamping mechanism, which includes the first clamping block 4, the second clamping block 5, the adjusting plate 8, the guide groove 10 and the guide block 9.

[0039] The first clamping block 4 is disposed in the first sliding groove 19 opened on the surface of the lower housing 2 and is located on the surface of the second clamping block 5. The second clamping block 5 is movably disposed inside the lower housing 2. The lower housing 2 is provided with a second sliding groove 20 corresponding to the second clamping block 5. The second clamping block 5 moves linearly back and forth along the extension direction of the second sliding groove 20. Limiting blocks 16 are provided on both sides of the second sliding groove 20. The limiting blocks 16 cooperate with the second clamping block 5 to guide and limit the second clamping block 5, so that the second clamping block 5 can only move along the second sliding groove 20, and avoids swaying during the movement.

[0040] The second clamping block 5 is connected to the adjusting plate 8 via the horizontal plate 122. When the second clamping block 5 moves, it drives the adjusting plate 8 to move synchronously. The adjusting plate 8 is symmetrically provided with guide grooves 10. Each first clamping block 4 is slidably connected to the corresponding guide groove 10 via a guide block 9. When the second clamping block 5 moves up and down along the second sliding groove 20, the adjusting plate 8 moves synchronously, and the guide block 9 slides relative to the guide groove 10, so that the vertical linear motion of the second clamping block 5 is converted into the horizontal movement of the first clamping block 4, thereby driving the two first clamping blocks 4 to open or clamp synchronously, realizing the linkage clamping between the three clamping blocks.

[0041] like Figure 11 As shown, in order to ensure the stability of the movement of the adjusting plate 8, a guide plate 24 is provided inside the upper housing 1. The guide plate 24 slides with the adjusting plate 8 to guide the adjusting plate 8, so that the adjusting plate 8 keeps moving along the movement direction of the second clamping block 5, thereby improving the stability of the clamping mechanism during operation.

[0042] like Figure 7 As shown, in order to provide clamping restoring force to the clamping mechanism, this embodiment is provided with a tensioning mechanism 12, which includes a horizontal plate 122, a connecting column 121, a positioning block 123 and a tension spring 124.

[0043] A horizontal plate 122 is disposed between the second clamping block 5 and the adjusting plate 8. Positioning blocks 123 are respectively provided at both ends of the horizontal plate 122. The positioning block 123 located above the horizontal plate 122 cooperates with the positioning hole 11 on the adjusting plate 8, and the positioning block 123 located below the horizontal plate 122 cooperates with the positioning hole 11 on the second clamping block 5, so that the horizontal plate 122 is connected to the second clamping block 5 and the adjusting plate 8 respectively. When the second clamping block 5 moves, since the second clamping block 5 is fixedly connected to the adjusting plate 8, the horizontal plate 122 moves synchronously with the second clamping block 5 and the adjusting plate 8 under the cooperation of the positioning block 123, so that the horizontal plate 122, the second clamping block 5 and the adjusting plate 8 are linked together.

[0044] A spring groove 25 is provided on the side of the adjusting plate 8 facing the horizontal plate 122. A tension spring 124 is disposed in the spring groove 25. One end of the tension spring 124 is connected to the connecting post 121, and the other end is fixed to the lower housing 2. When the second clamping block 5 moves downward, the second clamping block 5 drives the horizontal plate 122 and the adjusting plate 8 to move downward synchronously, and the connecting post 121 simultaneously stretches the tension spring 124. When the external force is released, the tension spring 124 releases its elastic potential energy, driving the horizontal plate 122, the adjusting plate 8 and the second clamping block 5 to reset synchronously. During the reset process, the adjusting plate 8 drives the two first clamping blocks 4 to move inward synchronously through the sliding cooperation between the guide groove 10 and the guide block 9, thereby completing the automatic clamping of the mobile phone.

[0045] like Figure 8 and Figure 9 As shown, in order to lock the clamping position, this embodiment provides a limiting mechanism 15. A limiting groove 14 is formed in the second clamping block 5 along its moving direction. The limiting groove 14 penetrates at least one side wall of the second clamping block 5. A plurality of teeth 13 are arranged sequentially in the limiting groove 14 along the moving direction of the second clamping block 5. Each tooth 13 is distributed at equal or unequal intervals along the moving direction of the second clamping block 5. Each tooth 13 corresponds to a different clamping stroke position of the second clamping block 5.

[0046] The limiting mechanism 15 includes a pawl 151, a connecting rod 152, a movable rod 153, a lever 154, and a pin 155. The pawl 151 is fixedly mounted on one end of the connecting rod 152. The connecting rod 152 is rotatably mounted in the lower housing 2 via a fixing post 17, allowing the pawl 151 to reciprocate around the pin 155 within a preset angle range and selectively engage with the teeth 13 at different positions in the limiting groove 14. The other end of the connecting rod 152 is movably connected to the movable rod 153. The lower end of the connecting rod 152 is fixedly connected to the lever 154, which passes through a movable groove 18 on the lower housing 2 and extends out of the lower housing 2, allowing the user to perform a toggle operation from the outside.

[0047] A pressure cover plate 28 is fixedly installed on the side of the lower housing 2 by a fixing bolt 6. A pressure groove 26 is opened on the opposite surface of the lower housing 2 and the pressure cover plate 28. The end of the movable rod 153 away from the connecting rod 152 is movably installed in the pressure groove 26 and can reciprocate within the pressure groove 26. A pressure spring 27 is installed in the pressure groove 26. One end of the pressure spring 27 abuts against the lower housing 2, and the other end abuts against the movable rod 153. The pressure spring 27 is always in a compressed state, continuously applying an elastic force to the movable rod 153 in the direction of the connecting rod 152. The pressure spring 27 pushes the movable rod 153, causing the connecting rod 152 to maintain a tendency to rotate in the direction of the teeth 13, ensuring that the pawl 151 can stably engage with the teeth 13 in different working positions, and preventing the pawl 151 from accidentally disengaging from the teeth 13 due to vibration or impact.

[0048] The pawl 151 has a first ratchet surface and a second ratchet surface that are arranged opposite to each other, forming an angle between them and together creating a V-shaped structure. The first ratchet surface is used to achieve a one-way locking engagement with the tooth 13 in a first direction, and the second ratchet surface is used to achieve a one-way locking engagement with the tooth 13 in a second direction, with the first direction being opposite to the second direction.

[0049] Specifically:

[0050] When the lever 154 is in the first working position, the connecting rod 152 rotates around the pin 155 to the first angle, and the first serrated surface of the pawl 151 faces the tooth 13 and engages with the tooth 13. At this time, a one-way locking engagement is formed between the pawl 151 and the tooth 13 in the first direction: the second clamping block 5 is allowed to move in the first direction (e.g., upward), but is restricted to move in the second direction opposite to the first direction (e.g., downward). When the motorcycle travels on a bumpy road or speed bump, the mobile phone generates a downward impact force due to inertia and acts on the second clamping block 5. Since the engagement of the first serrated surface of the pawl 151 with the tooth 13 restricts the downward movement of the second clamping block 5, the impact force is effectively resisted by the limiting mechanism 15, thereby preventing the second clamping block 5 from continuing to slide downward under the action of inertia, and avoiding the first clamping block 4 from opening outward due to the linkage relationship, which would cause the mobile phone to loosen.

[0051] When the lever 154 is in the second working position, the connecting rod 152 rotates around the pin 155 to the second angle, and the second ratchet surface of the pawl 151 faces the tooth 13 and engages with the tooth 13. At this time, a one-way locking engagement in the second direction is formed between the pawl 151 and the tooth 13. The second clamping block 5 is allowed to move in the second direction (e.g., downward), but is restricted to move in the first direction (e.g., upward). This working position is mainly used for the release or adjustment of the second clamping block 5. When the user needs to remove the phone or readjust the clamping position, the lever 154 is moved to the second working position, and the second clamping block 5 can be pulled downward under the action of external force, so that the first clamping block 4 opens synchronously, thereby releasing the phone.

[0052] Since the second clamping block 5 and the adjusting plate 8 maintain synchronous movement, and are fixedly connected, the adjusting plate 8 drives the first clamping block 4 through the cooperation of the guide groove 10 and the guide block 9. Therefore, when the limiting mechanism 15 restricts the second clamping block 5's degree of freedom of movement in a certain direction, the adjusting plate 8's degree of freedom of movement in that direction is also simultaneously restricted. The relative movement between the guide groove 10 and the guide block 9 is locked, and the first clamping block 4 cannot move in the opening direction. That is, the limiting mechanism 15 indirectly achieves full linkage locking of the entire clamping mechanism by constraining the unidirectional movement of the second clamping block 5, preventing external impact loads from being converted into the opening displacement of the clamping mechanism through the transmission chain of the second clamping block 5, the adjusting plate 8, the guide groove 10, the guide block 9, and the first clamping block 4, thereby eliminating the possibility of the clamping mechanism being accidentally opened due to inertial impact at the source.

[0053] In this embodiment, the limiting mechanism 15 achieves bidirectional selectable unidirectional mechanical locking of the clamping mechanism through the one-way ratchet engagement of the pawl 151 and the teeth 13, combined with the continuous pressure of the pressure spring 27. This limiting mechanism 15 is compact and easy to operate; the user only needs to toggle the lever 154 to quickly switch between locked and released states, ensuring both the reliability of the phone holder on motorcycles under complex road conditions and the convenience of taking the phone out and putting it away during daily use.

[0054] As a further preferred option, the bottom of the lower housing 2 is provided with a connecting seat 22, which is connected to the motorcycle mounting bracket via a universal ball joint, so as to be installed on the motorcycle handlebars or rearview mirror bracket, and the tilt angle and left and right direction of the mobile phone bracket can be adjusted according to actual needs.

[0055] In use, pulling down the second clamping block 5 causes it to move downwards along the second sliding groove 20, simultaneously moving the horizontal plate 122 and the adjusting plate 8. The tension spring 124 in the tensioning mechanism 12 is also stretched. During this process, guided by the guide plate 24, the adjusting plate 8 maintains a linear motion, ensuring the precise fit between the guide groove 10 and the guide block 9. Since the first clamping block 4 is slidably connected to the guide groove 10 on the adjusting plate 8 via the guide block 9, as the adjusting plate 8 moves downwards, the guide block 9 slides along the guide groove 10, driving the two first clamping blocks 4 to move synchronously to both sides, thus creating a clamping space for placing the mobile phone.

[0056] After placing the phone in the wireless charging area 3, the second clamp 5 is released. Under the restoring force of the tension spring 124, the second clamp 5, the horizontal plate 122, and the adjusting plate 8 are simultaneously reset upward. The adjusting plate 8 drives the guide block 9 to slide in the opposite direction through the guide groove 10. The two first clamps 4 move inward synchronously, together with the second clamp 5, to complete the clamping of the phone.

[0057] After clamping is completed, the lever 154 is moved to the first working position. The lever 154 drives the connecting rod 152 to rotate around the pin 155, so that the first ratchet surface of the pawl 151 is engaged between the teeth 13 at the corresponding position in the limiting groove 14 of the second clamping block 5, thereby achieving one-way locking of the current position of the second clamping block 5, allowing the second clamping block 5 to move upward and restricting its downward movement.

[0058] When a motorcycle travels at high speed over speed bumps, potholes, or continuous bumpy sections, the mobile phone tends to move downwards relative to its support due to inertia. This load is transmitted to the second clamping block 5, attempting to push it further downwards. However, the engagement of the first ratchet surface of the pawl 151 with the teeth 13 restricts the downward movement freedom of the second clamping block 5, preventing it from moving further downwards. Consequently, the adjusting plate 8 cannot move downwards synchronously, and the guide groove 10 and guide block 9 no longer experience relative movement. The first clamping block 4 remains in its clamping position, preventing external impact loads from being converted into the opening displacement of the clamping mechanism. The limiting mechanism 15, by independently locking the second clamping block 5 in one direction, indirectly constrains the movement freedom of the adjusting plate 8 and the first clamping block 4, maintaining a stable mechanical locking state for the entire clamping mechanism. This effectively prevents the mobile phone from falling off due to accidental opening of the clamping mechanism caused by inertial impact when the vehicle travels over potholes.

[0059] When it is necessary to remove the phone, the lever 154 is moved to the second working position, and the second raked surface of the pawl 151 engages with the tooth 13. At this time, the second clamping block 5 is allowed to move downwards but is restricted from moving upwards. The user can pull down the second clamping block 5 to open the first clamping block 4 simultaneously and remove the phone.
