Description

Technical Field

[0001] This utility model belongs to the field of motorcycle parts technology, and in particular relates to an adjustable motorcycle windshield mounting bracket. Background Technology

[0002] During motorcycle riding, the windshield bracket, as the core component for mounting the windshield, directly affects the rider's comfort and riding safety. Traditional brackets generally use a fixed structure design, and their height parameters cannot be dynamically adjusted. This makes it difficult for the bracket to adapt to the personalized sitting posture characteristics of riders of different heights, and it cannot respond to the wind resistance management needs of diverse riding scenarios. For example, in short-distance urban commuting scenarios, riders often need a lower windshield height to maintain a clear field of vision; while in long-distance travel scenarios, a higher windshield height can effectively reduce wind resistance and alleviate rider fatigue. Because fixed brackets cannot adjust their height, in actual use, the windshield position often does not match the rider's line of sight, causing not only continuous neck muscle tension and obstructed vision, but also potentially inducing safety hazards at high speeds.

[0003] While existing adjustable mounts attempt to overcome the limitations of fixed height, multiple technical bottlenecks have been exposed in practical applications. Firstly, the adjustment range is severely limited; most designs only support minute adjustments at the centimeter level, failing to accommodate the significant changes in rider posture from short rides to long journeys, rendering the adjustment function practically useless. Secondly, the operation process is cumbersome and inefficient. Users must use external tools such as wrenches or screwdrivers to loosen fasteners or perform multiple manual unlocking, positioning, and locking operations. This complex process significantly increases the difficulty of adjustments during riding, especially in inclement weather or emergencies. Thirdly, the internal structure is overly complex, commonly employing multi-link linkage mechanisms or precision threaded transmission systems. These designs are constantly subjected to road bumps and engine vibrations during motorcycle operation, making them highly susceptible to fastener loosening, moving parts jamming, or transmission mechanism failure. This not only weakens the long-term adjustment stability of the mount but also significantly reduces user confidence and product reliability.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable motorcycle windshield mounting bracket, which has the advantages of simple operation, wide adjustment range, and stable and reliable structure, so as to solve the problems that traditional fixed brackets cannot adapt to different riding scenarios and existing adjustable brackets have limited adjustment range, cumbersome operation, complex structure and easy failure.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: an adjustable motorcycle windshield mounting bracket, including an upper bracket, a lower bracket, and an adjustment component. The upper bracket and the lower bracket are connected to each other and can be locked in a relative sliding arrangement along their length. The adjustment component is located between the upper bracket and the lower bracket and includes a locking block and an adjustment handle. The locking block is mounted on the upper bracket, and the lower bracket has a limiting rack corresponding to the locking block, which engages with the locking block. The upper bracket and the lower bracket are locked and limited by the engagement of the locking block and the limiting rack. The adjustment handle is mounted on the upper bracket in a controllable sliding manner along its length. The locking block can move synchronously with the sliding of the adjustment handle to engage with or disengage from the limiting rack.

[0007] Furthermore, the adjustment assembly also includes a pressure block, the adjustment handle has a first sliding groove extending along the length direction, the upper bracket is provided with a first mounting post, the adjustment handle and the upper bracket are slidably connected by the first mounting post being inserted into the first sliding groove, the pressure block is fixedly installed on the first mounting post, and the pressure block and the adjustment handle clamp and limit the locking block; the pressure block is provided with a limiting guide rail extending along the width direction, and the locking block is provided with a corresponding limiting sliding groove that slides with the limiting guide rail, and the locking block is guided by the limiting guide rail to reciprocate in a single degree of freedom along the width direction.

[0008] Furthermore, the adjusting handle is provided with a guide rail extending along its length, and the locking block is provided with an inclined guide groove that slides in cooperation with the guide rail; along the length direction, the guide rail is inclined, with the upper end of the guide rail inclined away from the central axis of the adjusting handle, and the lower end of the guide rail inclined towards the central axis of the adjusting handle; when the adjusting handle slides upward, the locking block is simultaneously driven to move along the width direction towards the central axis of the adjusting handle to move away from the limiting rack, and when the adjusting handle slides downward, the locking block is simultaneously driven to move along the width direction away from the central axis of the adjusting handle to approach and engage with the limiting rack.

[0009] Furthermore, the adjustment assembly also includes a tension spring, one end of which is connected to the lower end of the adjustment handle and the other end is connected to the lower part of the upper bracket. Under the action of the elastic force of the tension spring, the adjustment handle tends to move downward along the length direction.

[0010] Furthermore, the upper bracket is also provided with a second mounting post, and the lower bracket is provided with a second sliding groove extending along the length direction. The lower bracket and the upper bracket are slidably connected by the second mounting post being inserted into the second sliding groove.

[0011] Furthermore, multiple first mounting columns are provided, and the multiple first mounting columns are arranged linearly along the central axis of the upper bracket. The first sliding groove is provided at the central axis position of the adjustment handle, and at least one first sliding groove is provided. Multiple second mounting columns are provided, and the multiple second mounting columns are scattered. Multiple second sliding grooves are provided in one-to-one correspondence with the second mounting columns.

[0012] Furthermore, there are two locking blocks symmetrically arranged along the width direction. Two limiting racks are arranged in a one-to-one correspondence with the locking blocks. The two limiting racks are symmetrically arranged on both sides of the lower bracket along the width direction. The two locking blocks are located between the two limiting racks. The locking blocks are provided with limiting teeth that can be inserted and engaged with the limiting racks. The locking blocks are arranged with the limiting teeth facing the limiting racks. Two guide rails are provided symmetrically so that the two locking blocks can move in opposite directions synchronously with the sliding of the adjustment handle.

[0013] Furthermore, the upper end of the adjustment handle is bent away from the upper support to form an operating part.

[0014] The beneficial effects of this technical solution are as follows:

[0015] This utility model provides an adjustable motorcycle windshield mounting bracket. By sliding the adjustment handle, the locking block and the limiting rack are engaged or disengaged, allowing the upper and lower brackets to slide and lock relative to each other along their length. This facilitates convenient adjustment of the windshield height, enabling simple height adjustment operations. Locking and unlocking can be completed simply by sliding the adjustment handle, reducing the complexity of windshield height adjustment. It solves the problems of fixed height in traditional brackets and the cumbersome and narrow adjustment range of existing adjustable brackets. It has the advantages of simple operation, wide adjustment range, and stable and reliable structure, meeting the needs of more riders of different heights and riding scenarios, and providing a better riding experience.

[0030] 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.

[0031] Unless otherwise specified, the length and width directions in this embodiment are based on the upper bracket as a reference, while the up and down directions correspond to the up and down positions of the adjustable motorcycle windshield mounting bracket after installation. This is something that those skilled in the art can understand and will not be elaborated here.

[0032] The basic implementation examples are as follows: Figure 1-12 As shown: An adjustable motorcycle windshield mounting bracket includes an upper bracket 1, a lower bracket 2, and an adjustment assembly. The upper bracket 1 and the lower bracket 2 are connected to each other and can be locked in a relative sliding arrangement along their length. The adjustment assembly is located between the upper bracket 1 and the lower bracket 2. The adjustment assembly includes a locking block 5 and an adjustment handle 3. The locking block 5 is installed on the upper bracket 1. The lower bracket 2 has a limiting rack 201 that engages with the locking block 5 at the position corresponding to the locking block 5. The upper bracket 1 and the lower bracket 2 are locked and limited by the engagement of the locking block 5 and the limiting rack 201. The adjustment handle 3 is installed on the upper bracket 1 in a controllable sliding manner along its length. The locking block 5 can move synchronously with the sliding of the adjustment handle 3 to engage with or disengage from the limiting rack 201. Specifically, the upper bracket 1 and the lower bracket 2 together constitute the main structure of the motorcycle windshield mounting bracket. The upper bracket 1 is used to connect the windshield, while the lower bracket 2 is connected to the motorcycle body. They are designed to move relative to each other to adjust the windshield height. The adjustment assembly is the core mechanism for realizing the bracket height adjustment and locking functions. Its function is to control the relative position between the upper bracket 1 and the lower bracket 2 and provide a reliable locking mechanism to ensure the stability of the windshield at the set height. Furthermore, in the adjustment assembly, the locking block 5 is the actuator for realizing the locking function. Its structure is designed to mechanically cooperate with the limiting rack 201, locking the upper bracket 1 and the lower bracket 2 in a specific position through plugging or snapping. The adjustment handle 3 is the interface for user operation. By operating the adjustment handle 3, the locking block 5 can be moved, thereby unlocking and relocking the bracket to ensure smooth height adjustment. The limiting rack 201 set on the lower bracket 2 has a series of toothed structures or grooves on its surface. The limiting rack 201, through its toothed structure, engages with the corresponding structure of the locking block 5, providing multiple preset locking positions, allowing the bracket to be precisely locked at different heights. Thus, the adjustable motorcycle windshield mounting bracket of this embodiment, through the relative sliding arrangement of the upper bracket 1 and the lower bracket 2 and the locking mechanism of the adjustment components, achieves flexible adjustment of the windshield height. It also simplifies the operation process, avoiding the cumbersome adjustment and loosening issues of traditional brackets, thereby improving riding comfort and safety, and meeting the adaptability needs of different riders and diverse riding scenarios for windshield height.

[0033] In this embodiment, the adjustment assembly further includes a pressure block 4. The adjustment handle 3 has a first groove 301 extending along the length direction. The upper bracket 1 is provided with a first mounting post 101. The adjustment handle 3 and the upper bracket 1 are slidably connected by the first mounting post 101 being inserted into the first groove 301. The pressure block 4 is fixedly installed on the first mounting post 101. The pressure block 4 and the adjustment handle 3 clamp and limit the locking block 5. The pressure block 4 is provided with a limiting guide rail 401 extending along the width direction. The locking block 5 is correspondingly provided with a limiting groove 501 that slides with the limiting guide rail 401. The locking block 5 is guided by the limiting guide rail 401 and can reciprocate in a single degree of freedom along the width direction. Specifically, the pressure block 4 is a limiting component in the adjustment assembly. Its main function is to cooperate with the adjustment handle 3 to clamp and limit the locking block 5 to ensure the stability and accuracy of the locking block 5 during movement. The adjustment handle 3 has a first groove 301 extending along the length direction, which provides a guide path for the sliding of the adjustment handle 3 in the length direction. The upper bracket 1 is provided with a first mounting post 101. The first mounting post 101 can be a pin, bolt 7, or a column structure with a threaded hole that is fixed to or passes through the upper bracket 1. In this embodiment, it is preferably a column structure with a threaded hole along the central axis, and a bolt 7 is correspondingly fitted to ensure the stable connection between the adjusting handle 3 and the upper bracket 1, while not affecting the relative sliding between the two. The adjusting handle 3 is inserted into the first mounting post 101 on the upper bracket 1 through its first sliding groove 301, thereby realizing the sliding connection of the adjusting handle 3 relative to the upper bracket 1 and ensuring that the adjusting handle 3 moves along a preset path. The pressure block 4 is fixedly mounted on the first mounting post 101, meaning that the pressure block 4 is fixed relative to the upper bracket 1. Specifically, the first sliding groove 301 of the operating handle is first fitted onto the first mounting post 101 to form a sliding insertion structure. Then, the bolt 7 is passed through the pressure block 4 and connected to the threaded hole of the first mounting post 101 and tightened, thus fixing the pressure block 4 to the upper bracket 1. Simultaneously, the adjusting handle 3 is limited to the upper bracket 1 in the thickness direction, ensuring that the adjusting handle 3 can only slide and will not disengage from the upper bracket 1. During the movement of the locking block 5, the pressure block 4 and the adjusting handle 3 together clamp the locking block 5, thereby limiting its movement and preventing it from moving in an unexpected direction or wobbling. Furthermore, the pressure block 4 is provided with a limiting guide rail 401 extending in the width direction. This limiting guide rail 401 can be a raised rib or edge structure used to guide the movement of the locking block 5. The locking block 5 is provided with a limiting groove 501 that slides in conjunction with the limiting guide rail 401. The limiting groove 501 can be a groove that matches the shape of the guide rail. Through the cooperation between the limiting guide rail 401 and the limiting groove 501, the locking block 5 is precisely guided, allowing it to reciprocate with only one degree of freedom in the width direction, thereby ensuring that the locking block 5 can accurately engage or disengage from the limiting rack 201.Thus, through the above technical solution, by introducing the pressure block 4 and utilizing the cooperation of the adjusting handle 3, the pressure block 4, the first mounting post 101, and the first sliding groove 301, effective clamping and precise guidance of the locking block 5 are achieved. The first mounting post 101 is inserted into the first sliding groove 301 of the adjusting handle 3, allowing the adjusting handle 3 to slide stably along its length. The pressure block 4 is fixedly installed on the first mounting post 101 and, together with the adjusting handle 3, clamps and limits the locking block 5, thereby providing necessary support and constraint during the movement of the locking block 5. In addition, the limiting guide rail 401 on the pressure block 4 slides in cooperation with the limiting sliding groove 501 on the locking block 5, precisely guiding the locking block 5 to reciprocate along its width in a single degree of freedom. This structural design ensures the accuracy and stability of the movement trajectory of the locking block 5 when it engages or disengages the limiting rack 201, preventing the locking block 5 from deviating or jamming during movement, thereby significantly improving the reliability and smoothness of operation of the locking mechanism. In the locked state, the clamping action of the pressure block 4 and the adjusting handle 3 on the locking block 5 further enhances the stability of the connection between the locking block 5 and the limiting rack 201, effectively preventing accidental loosening due to vibration or external force, and improving the safety of the entire mounting bracket.

[0034] In this embodiment, the adjusting handle 3 is provided with a guide rail 302 extending along the length direction, and the locking block 5 is provided with an inclined guide groove 502 that slides with the guide rail 302. Along the length direction, the guide rail 302 is inclined, with the upper end of the guide rail 302 inclined away from the central axis of the adjusting handle 3 and the lower end of the guide rail 302 inclined towards the central axis of the adjusting handle 3. When the adjusting handle 3 slides upward, the locking block 5 is simultaneously driven to move along the width direction towards the central axis of the adjusting handle 3 to move away from the limiting rack 201. When the adjusting handle 3 slides downward, the locking block 5 is simultaneously driven to move along the width direction away from the central axis of the adjusting handle 3 to approach and engage with the limiting rack 201.

[0035] Specifically, the guide rail 302 on the adjusting handle 3 is a protruding structure machined into the body of the adjusting handle 3, extending along the length of the adjusting handle 3. The main function of the guide rail 302 is to cooperate with the guide groove 502 on the locking block 5, converting the longitudinal sliding of the adjusting handle 3 into the lateral movement of the locking block 5. The shape and size of the guide rail 302 should match the guide groove 502 to ensure smooth sliding cooperation between them. The corresponding inclined guide groove 502 on the locking block 5 is an inclined channel formed on the body of the locking block 5, and its size and inclination angle match the guide rail 302. When the guide rail 302 slides within the guide groove 502, the inward inclination of the guide groove 502 forces the locking block 5 to move along its width. The inclination angle of the guide groove 502 can be designed according to the required moving distance and operating force of the locking block 5 to achieve the best driving effect. The guide rail 302 extends along its length and is inclined. Specifically, the upper end of the guide rail 302 is inclined away from the central axis of the adjusting handle 3, while the lower end is inclined towards the central axis of the adjusting handle 3. This specific inclination ensures that the locking block 5 can perform the expected insertion or disengagement action when the adjusting handle 3 slides in different directions. For example, when the adjusting handle 3 slides upward, the inclined structure of the guide rail 302 pushes the guide groove 502, thereby driving the locking block 5 to move towards the central axis of the adjusting handle 3, that is, to move inward, away from the limiting rack 201. Conversely, when the adjusting handle 3 slides downward, the inclined structure of the guide rail 302 drives the locking block 5 to move away from the central axis of the adjusting handle 3, that is, to move outward, so that it approaches and inserts into the limiting rack 201. Thus, by setting an inclined guide rail 302 on the adjusting handle 3 and cooperating with the corresponding guide groove 502 on the locking block 5, the linkage between the sliding of the adjusting handle 3 along its length and the movement of the locking block 5 along its width is achieved. When the adjusting handle 3 slides upward, the inclined structure of the guide rail 302 drives the locking block 5 to move inward, separating it from the limiting rack 201, thereby releasing the locking state and facilitating relative sliding adjustment between the upper bracket 1 and the lower bracket 2. Conversely, when the adjusting handle 3 slides downward, the locking block 5 is driven to move outward, bringing it closer to and engaging with the limiting rack 201, achieving reliable locking. This design not only provides a compact and convenient locking block 5 driving method, effectively solving the problem of precise engagement and disengagement of the locking block 5, but also allows locking and unlocking to be completed with simple handle operation, significantly improving the ease of use and reliability of the adjusting bracket.

[0036] In this embodiment, the adjustment assembly also includes a tension spring 6. One end of the tension spring 6 is connected to the lower end of the adjustment handle 3, and the other end is connected to the lower part of the upper bracket 1. Under the elastic force of the tension spring 6, the adjustment handle tends to move downward along its length. Specifically, the tension spring 6 is a common elastic element whose main function is to generate an elastic restoring force when stretched, so that it returns to its original length. In this application, the tension spring 6 is configured to provide a continuous pulling force to drive the adjustment handle 3 to move in a specific direction. It can be implemented as a helical tension spring with hooks or rings at both ends for easy connection. When the spring is stretched, it stores elastic potential energy and applies a restoring force opposite to the stretching direction. This means that when the adjustment is completed, simply releasing the adjustment handle will cause it to slide downward spontaneously under the action of the elastic restoring force, thereby causing the locking block 5 to be inserted into the limiting rack 201 to form a lock. In a preferred embodiment, the tension springs 6 in this example are arranged in two parallel lines. Both the lower end of the adjusting handle 3 and the lower part of the upper bracket 1 are provided with hanging holes for attaching the tension springs 6. After installation, the tension springs 6 are in a pre-tensioned state. This arrangement ensures that the locking block 5 can be tightly engaged with the limiting rack 201 without external force. Thus, by introducing the tension springs 6 and connecting one end to the lower end of the adjusting handle 3 and the other end to the lower part of the upper bracket 1, the adjusting handle 3, under the elastic force of the tension springs 6, always tends to move downwards along its length. Given the guiding relationship between the adjusting handle 3 and the locking block 5, this downward movement of the adjusting handle 3 drives the locking block 5 to move away from the central axis of the adjusting handle 3, thereby bringing it closer to and automatically engaging with the limiting rack 201. This effectively solves the problem of incomplete locking or inaccurate positioning that may occur during manual operation, ensuring reliable engagement between the locking block 5 and the limiting rack 201. Therefore, this solution provides an automatic or assisted locking function, which significantly improves the locking reliability and ease of operation of the motorcycle windshield mounting bracket, avoids accidental unlocking due to vibration or accidental contact, and thus enhances the stability and safety of the entire bracket.

[0037] In this embodiment, the upper bracket 1 is further provided with a second mounting post 102, and the lower bracket 2 has a second sliding groove 202 extending along its length. The lower bracket 2 and the upper bracket 1 are slidably connected by the second mounting post 102 being inserted into the second sliding groove 202. In this embodiment, the structure of the second mounting post 102, the structure of the second sliding groove 202, and the connection principle of the second mounting post 102 are the same as those of the first mounting post 101. The purpose is to achieve a sliding connection between the upper bracket 1 and the lower bracket 2 while preventing them from separating. As a preferred method, the bolts 7 corresponding to the first mounting post 101 and the second mounting post 102 can be equipped with structural components such as stop rings 8, washers 9, and O-rings 10 to enhance connection stability, further improving user experience and the overall reliability of the bracket.

[0038] In this embodiment, multiple first mounting posts 101 are provided, arranged linearly along the central axis of the upper bracket 1. A first sliding groove 301 is located at the central axis of the adjusting handle 3, and at least one first sliding groove 301 is provided. Multiple second mounting posts 102 are provided, distributed in a scattered manner. Multiple second sliding grooves 202 are provided in one-to-one correspondence with each second mounting post 102. Specifically, the multiple first mounting posts 101 are designed to enhance the connection strength and stability between the adjusting handle 3 and the upper bracket 1. The linear arrangement of these mounting posts along the central axis of the upper bracket 1 ensures that the adjusting handle 3 maintains correct guidance during sliding, avoiding skewing or jamming due to uneven force. The first sliding groove 301 is located at the central axis of the adjusting handle 3 and is at least one. It can be a through groove penetrating the adjusting handle 3 or composed of multiple aligned short grooves, cooperating with the multiple first mounting posts 101 to guide the smooth sliding of the adjusting handle 3. This design effectively distributes the load borne by the adjustment handle 3 during operation, improving the reliability and smoothness of its sliding connection. Furthermore, in this embodiment, two first mounting posts 101 are provided, and the pressure block 4 is installed on the first mounting post 101 located at the lowest position. This placement further enhances the windshield adjustment range. Simultaneously, the multiple second mounting posts 102 are used to enhance the overall rigidity and torsional resistance of the sliding connection between the upper support 1 and the lower support 2. These second mounting posts 102 are arranged in a dispersed manner, for example, at the edges or key stress points of the connection area between the upper support 1 and the lower support 2, thereby constraining and guiding the relative sliding of the upper support 1 and the lower support 2 in multiple directions, effectively preventing relative rotation or lateral swaying during sliding. Correspondingly, the lower support 2 is provided with multiple second sliding grooves 202, each corresponding to a second mounting post 102, ensuring that each mounting post can slide independently and precisely within its corresponding groove. This achieves smooth and reliable length adjustment between the upper support 1 and the lower support 2, and effectively resists external impacts and vibrations. In a preferred embodiment, this example uses three second mounting posts 102 arranged in an inverted triangle at the lower part of the upper support 1. Thus, through the above technical solution, the single mounting post connection method is improved to the synergistic effect of multiple mounting posts, significantly enhancing the stability, reliability, and load-bearing capacity of each sliding connection part of the support. Multiple first mounting posts 101 are linearly arranged along the central axis of the upper bracket 1, and cooperate with the first sliding groove 301 at the central axis position of the adjusting handle 3, so that the force on the adjusting handle 3 is more uniform and the guidance is more precise during the sliding process, effectively avoiding shaking and jamming during operation, thereby ensuring the precise insertion and separation of the locking block 5 and the limiting rack 201, and improving the smoothness and convenience of the adjustment operation.Meanwhile, the distributed arrangement of multiple second mounting posts 102, and the multiple second sliding grooves 202 corresponding one-to-one with each second mounting post 102, provides multi-point support and multiple guides for the relative sliding between the upper bracket 1 and the lower bracket 2. This effectively suppresses the torsion and lateral displacement of the bracket during length adjustment, greatly enhancing the structural rigidity and vibration resistance of the entire mounting bracket. This allows the motorcycle windshield mounting bracket to maintain a stable support state in complex driving environments, extending the product's service life and improving user safety and experience.

[0039] In this embodiment, there are two locking blocks 5 symmetrically arranged along the width direction. Two limiting racks 201 are arranged in a one-to-one correspondence with each locking block 5, symmetrically arranged on both sides of the lower bracket 2 along the width direction. The two locking blocks 5 are positioned between the two limiting racks 201. Each locking block 5 has limiting teeth 503 that can interlock with the limiting racks 201. The locking blocks 5 are arranged with the limiting teeth 503 facing the limiting racks 201. Two symmetrical guide rails 302 are correspondingly arranged, allowing the two locking blocks 5 to move synchronously in opposite directions as the adjusting handle 3 slides. Specifically, the locking blocks 5 are no longer a single structure, but are designed as two independent or functionally separate components, symmetrically arranged along the width direction of the bracket with the central axis as the reference. These symmetrically arranged locking blocks 5 can be made from a single molded material, or they can be two independent components operating synchronously through a common drive mechanism. This design aims to increase the number of locking points, thereby improving the overall locking strength and stability. Corresponding to the two locking blocks 5, two limiting racks 201 are also provided. These two limiting racks 201 are symmetrically distributed along the width direction of the lower bracket 2 and respectively engage with the two locking blocks 5. The limiting racks 201 can be integrally formed on the lower bracket 2 by milling, stamping, or other methods, or they can be independent rack components fixed to the lower bracket 2 by riveting, welding, or bolting 7. Their function is to provide an independent and reliable engagement interface for each locking block 5. In order to achieve reliable mechanical locking, the locking block 5 is provided with limiting tooth profiles 503 that match the tooth profile of the limiting racks 201. These tooth profiles can be sawtooth, square, trapezoidal, or other geometric shapes that can achieve tight engagement. The installation direction of the locking block 5 is explicitly specified as such, with its limiting tooth profile 503 facing the limiting rack 201. This ensures that during locking operations, the teeth of the locking block 5 can correctly and effectively engage with the teeth of the limiting rack 201, forming a stable mechanical connection. To drive the two symmetrical locking blocks 5 to operate synchronously, the adjusting handle 3 is equipped with two symmetrical guide rails 302, forming an inverted V-shape. These two guide rails 302 respectively cooperate with the guide grooves 502 on the two locking blocks 5. When the adjusting handle 3 slides along the length direction, due to the inclined design of the guide rails 302, it drives the two locking blocks 5 to move synchronously in opposite directions along the width direction. For example, when the adjusting handle 3 slides upward, the two locking blocks 5 may synchronously move towards the direction closer to the central axis of the adjusting handle 3 to move away from the limiting rack 201; when the adjusting handle 3 slides downward, the two locking blocks 5 synchronously move away from the central axis of the adjusting handle 3 to approach and engage with the limiting rack 201. This synchronous reverse movement mechanism ensures that the two locking blocks 5 can lock or unlock simultaneously.Thus, by improving the locking structure of a single locking block 5 into a dual-point locking structure consisting of two symmetrically arranged locking blocks 5 along the width direction and two symmetrical limiting racks 201, the connection stability between the upper bracket 1 and the lower bracket 2 is significantly enhanced, effectively resisting vibrations and impacts from different directions. The symmetrical locking points can more effectively disperse and resist torsional forces, preventing the bracket from deflecting or loosening under wind pressure or vibration, thereby improving the bracket's torsional resistance. Furthermore, the simultaneous and symmetrical engagement of the two locking blocks 5 ensures that the locking force is evenly distributed on both sides of the bracket, avoiding localized wear or failure caused by excessive force at a single point, thereby extending the service life of the locking mechanism and the entire bracket. The synchronous reverse movement mechanism of the two locking blocks 5, driven by two symmetrical guide rails 302 on the adjustment handle 3, ensures the coordination and consistency of the locking and unlocking processes, improving the reliability and smoothness of operation, allowing users to adjust and fix the height of the motorcycle's windshield more conveniently and safely.

[0040] In this embodiment, the upper end of the adjustment handle 3 is bent away from the upper support 1 to form the operating part 303. Specifically, the upper end of the adjustment handle 3 is designed with a specific shape, that is, bent away from the upper support 1, to form an area that is convenient for the user to grip, apply force, or perform operations; this area is the operating part 303. The operating part 303 can be integrally formed with the adjustment handle 3, or it can be implemented by an additional component. For example, the bending angle can be designed according to actual needs and ergonomic principles; it can be a gentle arc bend or a near-right angle bend to accommodate different users' gripping habits. The surface of the operating part 303 can be designed with an anti-slip texture, or it can be covered with a material with a high coefficient of friction to increase stability when gripping. In addition, the bending of the operating part 303 away from the upper support 1 ensures that the user's hand has sufficient space during operation, avoiding interference with the upper support 1 or other components, thereby improving the smoothness of operation.

[0041] Through the above technical solution, the upper end of the adjustment handle 3 is bent away from the upper bracket 1 to form the operating part 303, providing the user with a gripping area that conforms to ergonomic principles. When the user needs to adjust the length of the motorcycle windshield mounting bracket, they can directly hold the operating part 303. Due to its bent design, it provides a more comfortable grip and a more effective point of force application. This allows the user to push or pull the adjustment handle 3 more easily and effortlessly, thereby quickly and accurately engaging or disengaging the locking block 5 from the limiting rack 201. This significantly improves the convenience and efficiency of the adjustment operation, avoids misoperation or operator fatigue caused by unreasonable handle design, and thus optimizes the overall user experience of the mounting bracket.
