[0050] As described in the background section, the process of taking out and placing smart terminals in related technologies is cumbersome. The inventors have discovered that this problem arises because current fixing brackets typically use mechanical locking structures to secure the smart terminal. For example, users must first open the clamping arm of the fixing bracket, place the smart terminal inside, and then manually operate the locking device (such as a knob, latch, or spring clip) to ensure the smart terminal's stability. Alternatively, the locking mechanism must be unlocked first, and then the fixing bracket must be pried open to remove the smart terminal. This results in cumbersome operation and inconvenience in taking out and placing the smart terminal.

[0051] To address the aforementioned technical problems, this application provides a fixing device and vehicle. It comprises a first fixed bracket and a second fixed bracket that are movable relative to each other. The first fixed bracket has a first locking element, and the second fixed bracket has a second locking element. When the installation space needs to be adjusted to accommodate smart terminals of different sizes, a drive handle moves the first fixed bracket to adjust the size of the installation space. Simultaneously, the drive handle can control the first and second locking elements to accurately and reliably complete unlocking or locking actions. This integrates the functions of changing the installation space size and unlocking / locking the fixed brackets into a relatively compact structure, eliminating the need for multiple steps of disassembly and installation as in related technologies. This simplifies the handling of smart terminals and greatly improves operational convenience and assembly / disassembly efficiency.

[0052] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0053] Please refer to Figure 1 and Figure 2 This application provides a vehicle 1, which can be a scooter, a balance bike, or an electric vehicle. The vehicle can also be a foldable vehicle for easy carrying. Specifically, the vehicle can be a foldable scooter, a foldable balance bike, a foldable bicycle, or a foldable electric vehicle.

[0054] The vehicle 1 includes a fixing device 10 and a front housing 20. The fixing device 10 is adapted to be connected to the vehicle to fix a smart terminal (e.g., a mobile phone). The fixing device 10 can be fixedly connected to the front housing 20 of the vehicle 1.

[0055] Please refer to Figure 3 The fixing device 10 includes a fixing bracket 100, wherein the fixing bracket 100 is used to fix the forehead housing, and the fixing bracket 100 has an installation space for accommodating the smart terminal or other components (such as a display screen).

[0056] The fixed bracket 100 includes a first fixed bracket 110 and a second fixed bracket 120, which are movably connected, for example, by sliding connection, to adjust the size of the installation space. It should be noted that the installation space can be directly enclosed by the first fixed bracket 110 and the second fixed bracket 120, or other options can be used. Exemplarily, the fixed bracket 100 may also include a third fixed bracket 130, which is connected to the second fixed bracket 120 and located on the side of the second fixed bracket 120 opposite to the first fixed bracket 110. Thus, the first fixed bracket 110, the second fixed bracket 120, and the third fixed bracket 130 together enclose the installation space.

[0057] In some embodiments, please refer to Figure 2 The second fixing bracket 120 is fixedly connected to the forehead housing 20 by fasteners 30. The fasteners 30 include, but are not limited to, screws.

[0058] Please continue to refer to this. Figure 3 The first fixed bracket 110 is provided with a first locking member 111, and the second fixed bracket 120 is provided with a second locking member 121. The first locking member 111 and the second locking member 121 cooperate with each other. For example, when the first fixed bracket 110 and the second fixed bracket 120 are fixedly connected, the first locking member 111 and the second locking member 121 are locked. When the first fixed bracket 110 and the second fixed bracket 120 need to move relative to each other to adjust the size of the installation space, the first locking member 111 and the second locking member 121 are unlocked.

[0059] The fixing device 10 also includes a drive handle 200, which is connected to the first fixing bracket 110. The drive handle 200 is used to drive the first fixing bracket 110 to move, and to unlock or lock the first locking member 111 and the second locking member 121.

[0060] When the installation space needs to be adjusted to accommodate smart terminals of different sizes, the drive handle 200 moves the first fixed bracket 110 to adjust the size of the installation space. At the same time, the drive handle 200 can also control the first locking member 111 and the second locking member 121 to accurately and reliably complete the unlocking or locking action. In this way, the functions of changing the size of the installation space and unlocking and locking the fixed bracket 100 can be integrated into a relatively compact structure. Unlike related technologies, there is no need to perform multiple steps of disassembly and installation, which simplifies the operation of taking out and putting in smart terminals and greatly improves the convenience of operation and disassembly and assembly efficiency.

[0061] It should be understood that the drive handle 200 can move the first fixed bracket 110 towards or away from the second fixed bracket 120. During this movement, the first locking member 111 and the second locking member 121 can be unlocked or locked. For example, one of the first locking member 111 and the second locking member 121 has a locking protrusion, and the other has a locking groove. When the smart terminal needs to be installed in the installation space, the drive handle 200 can move the first fixed bracket 110 away from the second fixed bracket 120 to increase the installation space. At the same time, the locking protrusion disengages from the locking groove, unlocking the first fixed bracket 110 and the second fixed bracket 120. Then, the smart terminal is placed in the installation space, and the drive handle 200 moves the first fixed bracket 110 towards the second fixed bracket 120. At this time, the locking protrusion is inserted into the locking groove, locking the first fixed bracket 110 and the second fixed bracket 120 and securing the smart terminal.

[0062] In addition to moving the first fixed bracket 110 toward or away from the second fixed bracket 120 to adjust the installation space, the drive handle 200 can also have other functions. For example, the drive handle 200 can drive the first locking member 111 on the first fixed bracket 110 to move toward or away from the second locking member 121.

[0063] For example, the drive handle 200 is rotatably connected to the first fixed bracket 110 and connected to the first locking member 111 via the bevel gear transmission assembly 300. Thus, the drive handle 200 can both move the first fixed bracket 110 toward or away from the second fixed bracket 120 to adjust the size of the installation space; and the drive handle 200 can also rotate about its rotation axis, and drive the first locking member 111 to rotate via the bevel gear transmission assembly 300, thereby unlocking or locking the first locking member 111 with the second locking member 121.

[0064] When a smart terminal needs to be installed, the drive handle 200 rotates around its rotation axis away from the ground, and drives the first locking member 111 to rotate via the bevel gear transmission assembly 300, and moves away from the second locking member 121, thereby unlocking the first locking member 111 and the second locking member 121, so that the first fixed bracket 110 and the second fixed bracket 120 are in an active state.

[0065] Then, the first fixed bracket 110 is moved away from the second fixed bracket 120 by the drive handle 200 to increase the installation space.

[0066] Then, the smart terminal is installed in the installation space, and the first fixed bracket 110 is moved toward the second fixed bracket 120 by the drive handle 200 until the first fixed bracket 110 and the second fixed bracket 120 clamp the smart terminal.

[0067] Finally, the drive handle 200 rotates about its rotation axis toward the ground, and drives the first locking member 111 to rotate via the bevel gear transmission assembly 300, and moves toward the second locking member 121, so as to lock the first locking member 111 and the second locking member 121.

[0068] In this embodiment, the adjustment of the installation space size, as well as the unlocking or locking of the first locking member 111 and the second locking member 121, are all driven by the drive handle 200. Furthermore, the connection between the drive handle 200 and the first locking member 111 is achieved through a bevel gear transmission assembly 300. This converts the rotation of the drive handle 200 into the movement of the first locking member 111, making the entire fixing device 10 more compact. Moreover, the bevel gear transmission assembly 300 can achieve power transmission and conversion within a limited space, avoiding the use of complex transmission mechanisms and reducing the number of parts and space occupied.

[0069] In one possible implementation, the drive handle 200 is rotatably connected to the first fixed bracket 110 via a pivot 400. Exemplarily, the drive handle 200 has a mounting protrusion 210 on the side facing the first fixed bracket 110, and the mounting protrusion 210 has a mounting hole 211 extending along a second direction, wherein the second direction is perpendicular to the direction from the first fixed bracket 110 to the second fixed bracket 120, i.e. Figure 3 The Y direction in the diagram. For ease of description, the direction from the first fixed bracket 110 to the second fixed bracket 120 can be considered the first direction. The first direction and the second direction are perpendicular to each other, and the first direction is... Figure 3 In the X direction.

[0070] The rotating shaft 400 passes through the mounting hole 211, and both ends of the rotating shaft 400 are fixedly connected to the first fixed bracket 110. It should be noted that the first fixed bracket 110 includes a mounting groove facing the drive handle 200, allowing the drive handle 200 and the bevel gear transmission assembly 300 to be installed within the mounting groove. This ensures that, in a stationary state, the drive handle 200 is accommodated within the mounting groove, preventing it from protruding from the first fixed bracket 110. On one hand, this significantly improves the utilization rate of the internal space of the first fixed bracket 110, making the entire fixing device 10 more compact and easily arranged inside a vehicle or in other confined installation environments without spatial conflicts with other equipment or components. On the other hand, it also prevents the drive handle 200, which protrudes from the first fixed bracket 110, from colliding with surrounding objects during vehicle operation or scratching personnel during movement, thus improving vehicle safety.

[0071] In this embodiment of the application, the bevel gear transmission assembly 300 includes a driving bevel gear 310 and a driven bevel gear 320. The driving bevel gear 310 is sleeved on the rotating shaft 400 and fixedly connected to the drive handle 200. The driven bevel gear 320 meshes with the driving bevel gear 310.

[0072] It should be noted that the active bevel gear 310 can also be fixedly connected to the drive handle 200 by screws, which can improve the stability of the connection between the active bevel gear 310 and the drive handle 200.

[0073] The first locking member 111 is connected to the driven bevel gear 320. The first locking member 111 and the driven bevel gear 320 can be either fixedly connected or detachably connected. For example, the first locking member 111 and the driven bevel gear 320 are formed as a single piece through in-mold injection molding. This improves the connection strength between the first locking member 111 and the driven bevel gear 320, thereby enhancing the stability of the drive handle 200 during the driving process.

[0074] It should be noted that the first fixed bracket 110 is also provided with a first connecting hole 112, which extends through the first fixed bracket 110 along the first direction and communicates with the mounting groove. Thus, the first connecting hole 112 is used for the first locking member 111 to pass through. A copper bushing can also be provided inside the first connecting hole 112, which utilizes the self-lubricating effect of the copper bushing to improve the smoothness of the first locking member 111 during rotation.

[0075] In one possible implementation, the first locking member 111 has a locking groove 1111, and the second locking member 121 has a locking portion 1211, which is selectively connected to the locking groove 1111. For example, when the first locking member 111 and the second locking member 121 need to be locked, the locking portion 1211 engages within the locking groove 1111 to achieve connection between the locking portion 1211 and the locking groove 1111. As another example, when the first locking member 111 and the second locking member 121 need to be unlocked, the locking portion 1211 disengages from the locking groove 1111 to achieve separation between the locking portion 1211 and the locking groove 1111.

[0076] The locking part 1211 and the locking groove 1111 fit together more tightly and stably. The locking part 1211 can be more firmly engaged in the locking groove 1111, forming a reliable locking structure, effectively preventing relative movement between the first fixed bracket 110 and the second fixed bracket 120, providing a more stable fixing effect for the smart terminal, preventing the smart terminal from shaking or falling off due to bumps, vibrations and other factors during vehicle operation, and providing a reliable guarantee for the normal use of the smart terminal.

[0077] It should be noted that the shape of the locking groove 1111 can be selected in various ways. For example, in a first direction, at least one inner wall of the locking groove 1111 is inclined relative to the first direction; wherein, the first direction is the direction in which the first fixed bracket moves away from or toward the second fixed bracket, i.e. Figure 3 In the X direction.

[0078] When the first locking member 111 rotates around its own axis, the locking part 1211 moves along the inner wall of the locking groove 1111. In this way, the inclined inner wall can play a guiding role, avoiding misalignment between the locking part and the locking groove due to the lack of clear guidance, ensuring that the locking part 1211 can accurately and smoothly enter the locking groove 1111, greatly improving the success rate and accuracy of locking.

[0079] It should also be noted that the second locking member 121 can be directly fixedly connected to the second fixed bracket 120, or it can be connected in other ways. For example, the second fixed bracket 120 is provided with a fixed shaft 122. One end of the second locking member 121 facing away from the locking portion 1211 is sleeved on the fixed shaft 122. For example, the end of the second locking member 121 facing away from the locking portion 1211 is bent to form a bent section 1212. A clamping area is formed between the bent section 1212 and the locking portion 1211, and the clamping area is sleeved on the fixed shaft 122.

[0080] When it is necessary to connect the second locking member 121 to the second fixed bracket 120, simply align the clamping area of ​​the second locking member 121 with the fixed shaft 122 and then gently slide it in. In this way, a rotatable connection point is formed between the second locking member 121 and the fixed shaft 122, allowing the second locking member 121 to swing at a certain angle around the fixed shaft 122. This makes it easier for the locking part 1211 to slide into or out of the locking groove 1111, reducing discomfort caused by component jamming or excessive resistance.

[0081] In this embodiment, the second locking member 121 has a certain elasticity, which facilitates a smoother and more fluid sliding process when it slides into or out of the locking groove 1111. When the locking portion 1211 of the second locking member 121 approaches the locking groove 1111, its elastic properties allow it to automatically fine-tune its posture and position according to the shape and angle of the entrance to the locking groove 1111, eliminating the need for the user to apply excessive external force to force alignment, thus greatly reducing the difficulty of operation. During the sliding process, the elasticity can buffer the impact force caused by slight dimensional differences or installation errors between components, avoiding harsh collisions and making the entire sliding action as natural as flowing water. When sliding out of the locking groove 1111, the elasticity helps the second locking member 121 to more easily overcome any possible friction and quickly and smoothly disengage from the locked state.

[0082] In one possible implementation, the number of locking grooves 1111 includes a plurality; the plurality of locking grooves 1111 are arranged along a first direction and located on at least one side of the second locking member 121 in the second direction; the first direction is the direction in which the first fixing bracket 110 is away from or toward the second fixing bracket 120, and the first direction intersects with the second direction.

[0083] In some embodiments, the locking groove 1111 is disposed on one side of the second locking member 121 in the second direction. In another embodiment, a portion of the plurality of locking grooves 1111 are disposed on one side of the second locking member 121 in the second direction, and the remaining locking grooves 1111 are disposed on the other side of the second locking member 121 in the second direction.

[0084] By using multiple locking slots 1111, the locking positions of the second locking member 121 and the first locking member 111 can be freely adjusted, ensuring that the smart terminal can be stably and reliably fixed in the installation space to meet diverse usage needs. For example, for larger smart terminals, the locking position may need to be adjusted to the outermost locking slot 1111 to provide more stable support; while for smaller smart terminals, the innermost locking slot 1111 can be selected to optimize the installation space.

[0085] In one possible implementation, the fixing device 10 further includes a first elastic reset member 500, which is disposed between the drive handle 200 and the first fixing bracket 110 and is connected to the drive handle 200 and the first fixing bracket 110 respectively.

[0086] The first elastic reset member 500 includes a spiral part 510 and a first arm 520 and a second arm 530 connected to the spiral part 510. The spiral part 510 is sleeved on the rotating shaft 400, the first arm 520 abuts against the drive handle 200, and the second arm 530 abuts against the first fixed bracket 110.

[0087] Without applying force to the drive handle 200, the first elastic reset member 500 can drive the active bevel gear 310 to rotate in the opposite direction, and then drive the first locking member 111 to rotate through the driven bevel gear 320 until the second locking member 121 is engaged in the locking groove 1111 of the first locking member 111, thereby locking the first fixed bracket 110 and the second fixed bracket 120.

[0088] In one possible implementation, a guide 113 is provided on the first fixed bracket 110; the first fixed bracket 110 is slidably connected to the second fixed bracket 120 through the guide 113.

[0089] The guide member 113 can be a guide groove or a guide shaft. In some embodiments, the guide member 113 is a guide shaft, and one end of the guide shaft is integrally formed with the first fixed bracket 110. For example, the guide member 113 and the first fixed bracket 110 can be formed by injection molding to improve the structural strength of the guide member 113 and the first fixed bracket 110.

[0090] Meanwhile, the second fixed bracket 120 is provided with a first guide hole 123, and the guide member 113 is inserted into the first guide hole 123. In this way, when the drive handle 200 moves the first fixed bracket 110 toward or away from the second fixed bracket 120, the guide member 113 can move along the first guide hole 123 to improve the stability of the first fixed bracket 110 during the movement.

[0091] Please continue to refer to this. Figure 3A second elastic reset member 114 and a limiting member 115 are sleeved on the guide member 113. The limiting member 115 is located at the end of the second elastic reset member 114 away from the first fixed bracket 110. The limiting member 115 is used to limit and fix the second elastic reset member 114. It should be understood that the limiting member 115 can be directly welded to the guide member 113, or it can be fixed by screws. For example, the limiting member 115 and the guide member 113 have internally threaded holes that are aligned. Screws are threaded into the internally threaded holes of the limiting member 115 and the guide member 113, thereby achieving a fixed connection between the limiting member 115 and the guide member 113.

[0092] In actual use, after the installation space enclosed by the first fixed bracket 110 and the second fixed bracket 120 is opened to a suitable position, the drive handle 200 is held in place. While pushing the drive handle 200 toward the second fixed bracket 120, the elastic force of the second elastic reset member 114 is used simultaneously until the first fixed bracket 110 and the second fixed bracket 120 clamp the smart terminal.

[0093] When the drive handle 200 is released, the first locking member 111 rotates in the opposite direction under the elastic restoring force of the first elastic reset member 500, thereby locking the first locking member 111 and the second locking member 121.

[0094] In this embodiment, after the drive handle 200 is released, the first locking member 111 is driven to rotate and lock under the elastic restoring force of the first elastic reset member 500, while the second elastic reset member 114 ensures that the bracket remains in close contact with the smart terminal, forming a dual fixing mechanism of "elastic pre-tightening + mechanical locking" to improve reliability.

[0095] In some embodiments, the second fixing bracket 120 is further provided with a second guide hole 124 and a mounting groove 125 communicating with the second guide hole 124, the opening of the mounting groove 125 being located on the top surface of the second fixing bracket 120. In other words, the bottom surface of the second fixing bracket 120 is used for the fixed connection of the vehicle's front shell, and the opening of the mounting groove 125 can only be located on the top surface of the second fixing bracket 120.

[0096] The first locking member 111 passes through the mounting groove 125 into the second guide hole 124. The second locking member 121 is disposed in the mounting groove 125 and is located on one side of the first locking member 111. It should be understood that when there are two second locking members 121, the two second locking members 121 can be located on both sides of the first locking member 111.

[0097] In this way, the second guide hole 124 provides a precise carrier for the installation of the first locking component 111, and reasonably accommodates part of the first locking component 111 therein. This not only ensures the accuracy of the installation position of the first locking component 111, but also protects the first locking component 111 and improves its service life.

[0098] On the other hand, the mounting groove 125 provides good installation conditions for the second locking member 121, avoiding loosening or failure of the second locking member 121 due to improper installation, and ensuring the stability and reliability of the entire fixing device 10 during long-term use.

[0099] In one possible implementation, the fixed bracket 100 further includes a third fixed bracket 130, which is connected to the second fixed bracket 120 and is disposed opposite to the first fixed bracket 110; that is, the first fixed bracket 110 and the third fixed bracket 130 are located on both sides of the second fixed bracket 120 in a first direction.

[0100] The first fixed bracket 110 is provided with a first receiving groove 116, and the third fixed bracket 130 is provided with a second receiving groove 131. The first receiving groove 116 and the second receiving groove 131 are arranged opposite to each other. One end of the smart terminal can be placed in the first receiving groove 116, and the other end of the smart terminal can be placed in the second receiving groove 131. In this way, the first fixed bracket 110 and the third fixed bracket 130 can provide support for the smart terminal, improving the stability of the smart terminal during the movement of the vehicle 1.
