Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a roof box that is easy to assemble and disassemble. Background Technology

[0002] With the increasing popularity of car travel and outdoor activities, roof boxes have become a widely adopted and important in-vehicle storage solution. Roof boxes not only increase vehicle storage space but also effectively protect luggage from weather conditions. Existing roof boxes are typically secured to a crossbar on the roof via a fixing device at their base. Removal is simple; just loosen the fixing device to remove the roof box. Users can easily install and remove roof boxes as needed, offering high flexibility.

[0003] However, existing roof boxes still have some drawbacks in actual use:

[0004] Firstly, the fixing devices are usually locking clips, etc., and require the use of tools such as wrenches to assist in the disassembly and assembly process. The steps are complicated, resulting in inconvenience, time and effort wasted in disassembly and assembly.

[0005] Secondly, disassembly and assembly operations usually need to be completed by the user on the roof. When the vehicle is high, it is difficult for the user to operate. In some cases, it is even necessary to stand on a stool or other structure to operate. If the center of gravity shifts during the operation, the user may fall, which poses a safety hazard.

[0006] Third, the installation process is entirely manual, which is laborious and prone to problems such as insecure installation and improper operation.

[0007] Therefore, how to design a roof box that is easy to assemble and disassemble, and which is not only easy to assemble and disassemble, but also secure and safe, is a technical problem that designers and developers need to solve. Utility Model Content

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] This utility model provides a roof box 10 that is easy to assemble and disassemble, aiming to ensure that it is not only easy to assemble and disassemble but also securely installed and highly safe. Figure 1 and Figure 2 As shown, the easy-to-assemble and disassemble roof box 10 includes: a box body 100, a drive unit 200, a fixing frame 300, and a clamping assembly 400. The drive unit 200 and the clamping assembly 400 are fixedly connected to the box body 100 through the fixing frame 300.

[0037] Preferably, the suitcase body 100 and the fixing frame 300 can be fixedly connected by screws, clips, or other techniques commonly used in the art. Similarly, the clamping assembly 400 and the fixing frame 300 can also be fixedly connected by the aforementioned techniques. In some embodiments, such as Figure 5As shown, the easily detachable roof box 10 of this utility model includes a mounting base 800, and a drive component 200 is mounted on a fixing frame 300 via the mounting base 800. Specifically, the mounting base 800 has a receiving hole 810, and the drive component 200 passes through the receiving hole 810 and is fixedly connected to the wall of the receiving hole 810. Further, the mounting base 800 has a connecting part 820, and the connecting part 820 is fixedly connected to the fixing frame 300.

[0038] To prevent the clamping component 400 from protruding too much from the luggage box body 100 when it is installed on the roof, which would cause the luggage box body 100 to be too high and thus make the vehicle unstable during driving, this utility model provides an installation groove 110 at the bottom of the luggage box body 100. The fixing bracket 300, the driving component 200 and the clamping component 400 are housed in the installation groove 110, thereby effectively avoiding this problem. At the same time, this utility model makes the roof luggage box 10, which is easy to install and remove, more compact and simpler in appearance.

[0039] Specifically, such as Figures 3 to 6 As shown, the clamping assembly 400 includes a first clamping arm 410, a second clamping arm 420, and a knob 430. The first clamping arm 410 has a first clamping claw portion 411 and a first rack portion 412, and the second clamping arm 420 has a second clamping claw portion 421 and a second rack portion 422. The first clamping claw portion 411 and the second clamping claw portion 421 cooperate with each other.

[0040] The knob 430 has a vortex wall 431. A first rack portion 412 and a second rack portion 422 respectively engage with the vortex wall 431. The drive member 200 drives the knob 430 to rotate around the center line 432 of the vortex wall 431. During rotation, the knob 430 causes the first clamping arm 410 and the second clamping arm 420 to move closer or further apart. A vortex groove 433 is formed inside the vortex wall 431. The first rack portion 412 and the second rack portion 422 extend into the vortex groove 433 and abut against the vortex wall 431. Understandably, the drive member 200, in conjunction with existing reducers or other transmission mechanisms, can convert electrical energy into mechanical energy, thereby driving its output shaft to rotate. This rotation of the output shaft directly or indirectly drives the knob 430 to rotate. The aforementioned reducers and other transmission mechanisms are common knowledge to those skilled in the art and will not be described in detail here. In some embodiments, the drive member 200 is a stepper motor.

[0041] Preferably, the easily detachable roof rack 10 of this invention includes a control component (not shown). The control component includes a control mainboard and a switch. The drive unit 200 is electrically connected to the control mainboard; the switch is also electrically connected to the control mainboard. The user can control the start and stop of the drive unit 200 via the switch. In some embodiments, the switch is disposed on the side wall of the rack body 100.

[0042] Preferably, the user can control the start and stop of the drive unit 200 via a mobile phone, or via a remote control or other structure.

[0043] like Figures 2 to 6 As shown, the clamping assembly 400 includes a housing 440, within which a first rack portion 412 and a second rack portion 422 are housed. A sliding groove 441 is provided at the bottom of the housing 440. The first gripper portion 411 and the second gripper portion 421 extend outside the housing 440 through the sliding groove 441 and are designed to slide along the groove 441, thereby guiding the sliding of the first and second clamping arms. Preferably, a vortex wall 431 at least partially extends into the housing 440 and engages with the first rack portion 412 and the second rack portion 422. The housing 440 protects the first rack portion 412 and the second rack portion 422, preventing debris such as sand and insects from affecting the sliding engagement between the vortex wall 431 and the first rack portion 412 or the second rack portion 422, thus ensuring the smooth operation of the clamping assembly 400 during clamping.

[0044] The working principle of the easily detachable and assembleable roof luggage box 10 of this utility model will be explained below in conjunction with the above structure. (Refer to...) Figures 1 to 6 As shown:

[0045] It should be noted that, as Figure 1 As shown, existing vehicles typically have two longitudinal bars 20 fixed to the roof, located on both sides of the roof and parallel to the vehicle's longitudinal direction. Two transverse bars 30 are horizontally mounted at both ends of the longitudinal bars 20. The roof rack is usually installed on the transverse bars 30 to ensure stable installation. The transverse bars 30 are generally fixed to the longitudinal bars 20 using a specific fixing structure. Various mature existing technologies can be used to fix the transverse bars 30 to the longitudinal bars 20, which are well-known in the field and will not be elaborated upon.

[0046] In use, the user places the easy-to-assemble and detachable roof box 10 of this utility model on the roof of the vehicle, aligns the clamping component 400 with the crossbar 30, and activates the drive component 200 to clamp the clamping component 400 onto the crossbar 30, thereby fixing the box body 100 onto the crossbar 30; when disassembling, the user activates the drive component 200 again, the clamping component 400 releases the crossbar 30, thereby allowing the easy-to-assemble and detachable roof box 10 of this utility model to be removed from the roof of the vehicle.

[0047] During operation, taking the installation of the suitcase body 100 as an example, the user activates the drive unit 200, and the knob 430 rotates around the center line 432 of the vortex wall 431 under the drive unit 200. During the rotation of the knob 430, the first rack portion 412 and the second rack portion 422 slide along the vortex groove 433 under the pressure of the vortex wall 431. Since the first gripper portion 411 and the second gripper portion 421 are limited to sliding along the sliding groove 441, the first clamping arm 410 and the second clamping arm 420 slide linearly along the sliding groove 441 under the drive unit 200. This causes the first gripper portion 411 and the second gripper portion 421 to approach each other until they tightly clamp the crossbar 30, thus completing the installation of the suitcase body 100. The process of disassembling the suitcase body 100 is similar to the process of installing it and will not be described in detail here.

[0048] Specifically, the drive unit 200 can drive the knob 430 to rotate in different ways. Two different embodiments are described below for reference.

[0049] Example 1:

[0050] like Figures 1 to 4 As shown, the easy-to-assemble and disassemble roof box 10 includes a worm gear 500, which is connected to the output shaft of the drive unit 200. Multiple teeth 434 are provided on the outer edge of the knob 430. The multiple teeth 434 are evenly spaced along the circumferential direction of the knob 430 and cooperate with the worm gear 500.

[0051] Preferably, at least two clamping components 400 are spaced apart on the fixed frame 300, the driving component 200 is located at one end of the fixed frame 300, and the worm gear 500 cooperates with at least two clamping components 400 simultaneously.

[0052] Furthermore, the number of driving components 200 and worm gears 500 is set to two, and the number of clamping components 400 is set to four, arranged in pairs side by side. The two worm gears 500 respectively cooperate with the two rows of clamping components 400. Understandably, at this time, one driving component 200 drives one worm gear 500 to rotate, and one worm gear 500 simultaneously drives two clamping components 400 to work.

[0053] Here is a brief explanation of the working principle of this embodiment: During operation, the drive component 200 drives the worm gear 500 to rotate. The torque on the worm gear 500 is transmitted to the knob 430 through the engagement of the gear teeth 434 and the tooth surface, thereby generating a thrust on the knob 430, causing the knob 430 to rotate around the center line 432 of the vortex wall 431, which in turn drives the first clamping arm 410 and the second clamping arm 420 to move closer to or further away from each other.

[0054] It should be noted that since one worm gear 500 drives two knobs 430 to rotate simultaneously, the two clamping components 400 can operate synchronously, thus ensuring stability during the clamping process and avoiding the problem of the luggage body 100 shifting during the clamping process due to asynchronous operation between multiple clamping components 400. At the same time, effective clamping can be achieved with a smaller number of drive components 200, which effectively reduces costs.

[0055] Example 2:

[0056] like Figure 5 and Figure 6 As shown, the drive unit 200 is located at the top of the knob 430. The knob 430 has a connecting hole 435 at the center of the vortex wall 431. The output shaft of the drive unit 200 passes through the connecting hole 435 and is connected to the hole wall of the connecting hole 435 through a connector (not shown).

[0057] Preferably, the connector can be an expansion sleeve. The inner ring of the expansion sleeve contracts and grips the output shaft of the drive component 200, while the outer ring of the expansion sleeve expands and presses against the wall of the connecting hole 435. This allows the torque on the output shaft of the drive component 200 to be effectively transmitted to the knob 430 through the high coefficient of friction at the connection.

[0058] Furthermore, the number of clamping components 400 and driving components 200 is set to four, with each of the four clamping components 400 corresponding to one of the four driving components 200. The four clamping components 400 are respectively located at the four corners of the mounting slot 110 to ensure the stability of clamping.

[0059] Here is a brief explanation of the working principle of this embodiment: During operation, the output shaft of the drive member 200 rotates. Due to the high coefficient of friction between the output shaft and the connecting member, the torque on the output shaft can be effectively transmitted to the connecting member. Then, through the tight fit between the connecting member and the hole wall of the connecting hole 435, the torque is transmitted to the knob 430, thereby driving the knob 430 to rotate around the center line 432 of the vortex wall 431, which in turn drives the first clamping arm 410 and the second clamping arm 420 to move closer to or further away from each other.

[0060] It should be noted that at this time, the driving component 200 directly drives the knob 430 to rotate, which reduces the number of transmission components, thereby reducing energy loss in the transmission process and achieving higher transmission efficiency.

[0061] It should be emphasized that, compared with the prior art, the easily detachable roof box 10 of this utility model has the following advantages:

[0062] Firstly, the luggage body 100 can be installed without manual operation by the user, relying solely on the start-stop drive unit 200. No other auxiliary tools are required, avoiding the problem of being unable to disassemble or install the luggage body 100 due to the loss of auxiliary tools. At the same time, the operation is simple and quick.

[0063] Secondly, users can disassemble and assemble the trunk body 100 from the side of the vehicle without having to operate it on the roof, thus eliminating the need to stand at a high position and eliminating safety hazards, making it highly safe.

[0064] Third, the clamping component 400 clamps the crossbar 30 through the driving component 200, so that the clamping force provided by the clamping component 400 is no longer limited by human strength. This not only improves the clamping efficiency, but also ensures the stability of the clamping, making the luggage body 100 firmly installed.

[0065] Preferably, in an embodiment not shown, pressure sensors are respectively installed on the first clamping arm 410 and the second clamping arm 420, and the pressure sensors are electrically connected to the control mainboard. When the pressure sensor detects that the pressure on the first clamping arm 410 or the second clamping arm 420 reaches a preset threshold, it transmits information to the control mainboard. The control mainboard receives the signal and controls the drive unit 200 to stop operating, thereby avoiding damage to the clamping assembly 400 or the crossbar 30 due to excessive pressure.

[0066] In some embodiments, a slide rail is provided on the side wall of the housing 440. A first connecting portion (not shown) is provided between the first rack portion 412 and the first gripper portion 411, and a second connecting portion (not shown) is provided between the second rack portion 422 and the second gripper portion 421. A slider is provided on both the first and second connecting portions, and the slider cooperates with the slide rail. In this way, the sliding of the first gripper arm 410 and the second gripper arm 420 is guided by the cooperation of the slider and the slide rail, which not only further ensures that the first gripper arm 410 and the second gripper arm 420 can slide smoothly, but also ensures the accuracy of clamping.

[0067] Preferably, such as Figure 2 As shown, the sliding paths of the first gripper portion 411 and the second gripper portion 421 are parallel and do not overlap. This avoids the problem of collision and interference between the first gripper portion 411 and the second gripper portion 421 when they slide towards each other. Specifically, there are two sliding grooves 441, and the first gripper portion 411 and the second gripper portion 421 are respectively disposed in the two sliding grooves 441.

[0068] In some embodiments, at least a portion of the first gripper portion 411 and at least a portion of the second gripper portion 421 are provided with anti-slip material. Preferably, the anti-slip material is disposed on the contact surfaces of the first gripper portion 411 and the second gripper portion 421 with the crossbar 30. This effectively improves the stability of clamping and avoids surface wear caused by direct rigid contact between the first gripper portion 411 and the second gripper portion 421 and the crossbar 30. Preferably, the anti-slip material is disposed on the first gripper portion 411 and the second gripper portion 421 by means of adhesive bonding, spraying, or other methods.

[0069] In some embodiments, such as Figure 1 As shown, the easily detachable roof box 10 includes an energy storage component 600. The energy storage component 600 is housed within and detachably connected to the roof box body 100. The energy storage component 600 provides electrical power to the drive component 200, and is electrically connected to the drive component 200. Understandably, placing the energy storage component 600 within the roof box body 100 protects it from rain, gravel, and other elements that could affect its normal operation. A battery may be housed inside the energy storage component 600. When the battery is depleted, the user can remove the energy storage component 600 from the mounting bracket 300 and recharge it.

[0070] In some embodiments, the drive unit 200 is electrically connected to the vehicle's power supply via a wire. In this case, the vehicle's power supply can power the drive unit 200 for a long time, so users do not need to worry about battery life and improve the user experience.

[0071] Preferably, such as Figure 7 As shown, the mounting bracket 300 is equipped with casters 700, which allow the suitcase body 100 to be moved easily. This allows users to easily move the suitcase body 100 and adjust its position.

[0072] In summary, the roof box 10 of this utility model, which is easy to assemble and disassemble, is not only easy to assemble and disassemble, but also securely installed and highly safe.

[0073] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
