Technical Field

[0001] This application relates to the technical field of automotive parts, and more particularly to a stationary device and a motorized device. Background Technology

[0002] Nowadays, with the continuous development of living standards, cars have gradually become one of the important means of transportation for people. In order to avoid the situation where the vehicle cannot move due to a tire puncture, existing car manufacturers usually equip cars with a spare tire when they leave the factory. However, the existing spare tires are usually fixed to the car frame or body by bolts. This kind of fixing method is not stable when encountering bumps during the car's driving, which may result in the spare tire becoming loose or even falling off. Summary of the Invention

[0003] This application provides a fixing device to solve the problem that existing spare tire fixing methods are unstable when encountering bumps during vehicle operation, which can lead to the spare tire becoming loose or even falling off.

[0004] In a first aspect, embodiments of this application provide a fixing device, including:

[0005] First connection component; and

[0006] A second connecting assembly is rotatably configured relative to the first connecting assembly. The second connecting assembly includes a driving member and a driven member rotatably connected to each other. The driving member is disposed on one side of the driven member, and the driven member engages with the first connecting assembly.

[0007] When the driving member moves in a direction close to the driven member to drive the driven member to rotate, the driven member can abut against the first connecting component and rotate relative to the driving member to separate the driven member from the first connecting component.

[0008] In one embodiment, the first connecting component includes a first mounting portion, a first connecting portion, and a first engaging portion connected one-to-one. The first mounting portion is used to connect a spare tire. The driven member includes a second mounting portion, a second connecting portion, and a second engaging portion connected one-to-one. The second mounting portion is used to connect the driving member. The first engaging portion and the second engaging portion are both hook-shaped.

[0009] In one embodiment, the angle formed between the first engaging portion and the first connecting portion is 100° to 120°, and / or the angle formed between the second engaging portion and the second connecting portion is 100° to 120°.

[0010] In one embodiment, the driving member includes a plate and a first extension, the second mounting portion partially overlaps with the plate, the fixing device includes a first connector that passes through the overlapping area of ​​the second mounting portion and the plate to rotatably connect the second mounting portion to the plate, the first extension extends in a direction away from the second mounting portion, and the second connecting component further includes a handle that is fixedly connected to one end of the first extension away from the second mounting portion.

[0011] In one embodiment, the fixing device further includes a fixing base and a second connecting member. The fixing base is disposed on the side of the driving member away from the driven member. The fixing base includes a first limiting plate and a second limiting plate, which are spaced apart to form a limiting space. The driving member further includes a second extension, which extends in a direction toward the first connecting component and is disposed within the limiting space. The second connecting member passes through the first limiting plate, the second extension, and the second limiting plate to rotatably connect the second extension to the fixing base.

[0012] In one embodiment, when the fixing device is in a locked state, the fixing device includes a first rotation region and a second rotation region located on both sides of the connecting line formed between the locking portion of the first locking portion and the second locking portion and the first connector. The second connecting component rotates along the direction from the first rotation region to the second rotation region to unlock the fixing device, wherein the second connector is located within the second rotation region.

[0013] In one embodiment, the handle further includes a third extension located within the limiting space, and the fixing device further includes a third connector that passes through the first limiting plate, the third extension, and the second limiting plate, thereby detachably connecting the handle to the fixing base.

[0014] In one embodiment, the third connector includes a housing, a pull ring, and a limiting member. The housing is hollow to form a hollow region. The pull ring is fixedly connected to the limiting member. The limiting member is movably disposed within the hollow region and elastically connected to the inner wall of the housing.

[0015] In one embodiment, the second connecting component further includes an anti-slip sleeve fitted onto the end of the handle away from the drive member.

[0016] Secondly, embodiments of this application also provide a motorized device, including:

[0017] The rear door panel is used to install the spare tire;

[0018] The rear bumper is connected to the rear door panel; and

[0019] As in any of the above embodiments, the fixing device has one end for connecting to the spare tire and the other end for connecting to the rear bumper to fix the spare tire.

[0020] The fixing device provided in this application embodiment can be applied to the field of vehicle technology, specifically for fixing a spare tire to a car. The fixing device includes a first connecting component and a second connecting component. The first connecting component can be used to connect the spare tire, and the second connecting component can be used to connect the car. The second connecting component is rotatably configured relative to the first connecting component. The second connecting component includes a driving member and a driven member that are rotatably connected to each other. The driving member is disposed on one side of the driven member, and the driven member engages with the first connecting component.

[0021] It is understood that in this embodiment, when the driven member engages with the first connecting assembly, the spare tire can be fixed to the vehicle. When it is necessary to unlock the spare tire, an external force can be applied to the driving member in the direction close to the driven member, causing the driving member to rotate. When the driving member rotates to a certain angle, since the driving member and the driven member are rotatably connected, the driving member will drive the driven member to rotate, and the part of the driven member engaged with the first connecting assembly will continuously abut against the first connecting assembly. During the continuous abutment of the driven member (while the driven member remains stationary), since the driving member is constantly rotating and the driven member is rotatably connected to the driving member, the relative angle between the driven member and the driving member will continuously increase with the rotation amplitude of the driving member. At this time, an external force (i.e., a reverse force) is applied to the driving member in the direction away from the driven member. Since the relative angle between the driven member and the driving member increases, the driven member will not contact the first connecting assembly, thereby achieving the purpose of unlocking and separating the spare tire from the vehicle.

[0022] When it is necessary to fix the spare tire to the car, an external force can be applied first to engage the driven member and the first connecting component. Then, an external force is applied to the driving member in a direction away from the driven member, so that the driving member can drive the driven member to rotate in a direction away from the first connecting component, making the engagement between the driven member and the first connecting component tighter. When the driving member rotates to a certain angle, the engagement between the driven member and the first connecting component is most secure. At this point, the external force applied to the driving member in a direction away from the driven member is stopped, and the driving member is kept stationary. This achieves the purpose of stable and reliable fixing of the spare tire and the car. Compared with the screw connection method of the prior art, the fixing device provided in this application embodiment can achieve the engagement and unlocking of the spare tire and the car in a simple step, further ensuring that the spare tire is more stable when encountering bumps during the car's driving process, and avoiding the situation where the spare tire becomes loose or even falls off.

Detailed Implementation

[0032] 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.

[0033] Nowadays, with the continuous development of living standards, cars have gradually become one of the important means of transportation for people. In order to avoid the situation where the vehicle cannot move due to a tire puncture, existing car manufacturers usually equip cars with a spare tire when they leave the factory. However, the existing spare tires are usually fixed to the car frame or body by bolts. This kind of fixing method is not stable when encountering bumps during the car's driving, which may result in the spare tire becoming loose or even falling off.

[0034] To address the aforementioned technical issues, this application provides a fixing device 100 and a motorized device 200. The fixing device 100 is applicable to the field of vehicle technology and specifically serves to fix a spare tire to a vehicle. Please refer to... Figures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the fixing device 100 provided in the embodiments of this application. Figure 2 for Figure 1 The structural schematic diagram of the fixing device 100 from another perspective is shown. Figure 3 This is a schematic diagram illustrating the unlocking process of the fixing device 100 provided in this embodiment of the application.

[0035] like Figures 1-3 As shown, in one embodiment of this application, the fixing device 100 includes a first connecting component 110 and a second connecting component 120. The first connecting component 110 can be used to connect a spare tire, and the second connecting component 120 can be used to connect a car. The second connecting component 120 is rotatably configured relative to the first connecting component 110. The second connecting component 120 includes a driving member 121 and a driven member 122 that are rotatably connected to each other. The driving member 121 is disposed on one side of the driven member 122, and the driven member 122 is engaged with the first connecting component 110.

[0036] It is understood that, in this embodiment, when the driven member 122 engages with the first connecting assembly 110, the spare tire can be secured to the vehicle. When it is necessary to unlock the spare tire, an external force can be applied to the driving member 121 in a direction close to the driven member 122, causing the driving member 121 to move along... Figure 3The rotation direction is shown. When the drive member 121 rotates to a certain angle, since the drive member 121 and the driven member 122 are rotatably connected, the drive member 121 will drive the driven member 122 to rotate, and the part of the driven member 122 that is engaged with the first connecting component 110 will continuously abut against the first connecting component 110. During the continuous abutment of the driven member 122 (while the driven member 122 remains stationary), since the drive member 121 is constantly rotating and the driven member 122 is rotatably connected to the drive member 121, the relative angle between the driven member 122 and the drive member 121 will continuously increase with the rotation amplitude of the drive member 121. At this time, if an external force (i.e., a counterforce) is applied to the drive member 121 in a direction away from the driven member 122, since the relative angle between the driven member 122 and the drive member 121 increases, the driven member 122 will not contact the first connecting component 110, thereby achieving the purpose of unlocking and separating the spare tire and the car.

[0037] When it is necessary to fix the spare tire to the car, an external force can be applied first to engage the driven member 122 and the first connecting component 110. Then, an external force is applied to the driving member 121 in a direction away from the driven member 122, so that the driving member 121 can drive the driven member 122 to rotate in a direction away from the first connecting component 110, and make the engagement between the driven member 122 and the first connecting component 110 tighter. When the driving member 121 rotates to a certain angle, the engagement between the driven member 122 and the first connecting component 110 is the most secure. At this time, the external force applied to the driving member 121 in a direction away from the driven member 122 is stopped, and the driving member 121 is kept stationary. This achieves the purpose of stable and reliable fixing of the spare tire and the car. Compared with the screw connection method of the prior art, the fixing device 100 provided in this application embodiment can realize the engagement and unlocking of the spare tire and the car in a simple step, further ensuring that the spare tire is more stable when encountering bumps during the car's driving process, and avoiding the situation where the spare tire becomes loose or even falls off.

[0038] In some embodiments, such as Figure 2 As shown, the first connecting component 110 may include a first mounting part 111, a first connecting part 112, and a first engaging part 113 connected one to one. The first mounting part 111 can be used to connect the vehicle's spare tire to achieve the purpose of fixing the first connecting component 110 to the spare tire, while the first connecting part 112 is used to connect the first mounting part 111 and the first engaging part 113.

[0039] Please continue to refer to Figure 3The driven member 122 may include a second mounting portion 1221, a second connecting portion 1222, and a second engaging portion 1223 connected one-to-one. The second mounting portion 1221 is used to connect to the driving member 121 so that the driving member 121 drives the driven member 122 to rotate. The second connecting portion 1222 is used to connect the second mounting portion 1221 and the second engaging portion 1223. The second engaging portion 1223 is used to engage with the first engaging portion 113 to achieve the locking purpose of the fixing device 100. Both the first engaging portion 113 and the second engaging portion 1223 can be hook-shaped, thereby achieving a better locking purpose for the fixing device 100 and further ensuring that the spare tire is more stable when encountering bumps during vehicle operation, preventing the spare tire from becoming loose or even falling off.

[0040] Furthermore, such as Figure 2 As shown, in another embodiment of this application, the angle formed between the first engaging portion 113 and the first connecting portion 112 can be 100° to 120°, and the angle formed between the second engaging portion 1223 and the second connecting portion 1222 can also be 100° to 120°. Thus, when the first engaging portion 113 and the second engaging portion 1223 engage with each other to achieve the purpose of fixing the spare tire to the car, not only can the engagement connection between the first engaging portion 113 and the second engaging portion 1223 be made more secure, but it can also prevent the first engaging portion 113 and the second engaging portion 1223 from disengaging during the locking process.

[0041] like Figure 1 and Figure 2 As shown, in some embodiments, the driving member 121 may include a plate 1211 and a first extension 1212. The second mounting portion 1221 partially overlaps with the plate 1211. Meanwhile, the fixing device 100 includes a first connector 131, which passes through the overlapping area of ​​the second mounting portion 1221 and the plate 1211 to achieve a rotatable connection between the second mounting portion 1221 and the plate 1211. The first extension 1212 may extend in a direction away from the second mounting portion 1221. Please refer to [further details omitted]. Figure 2 In this embodiment, the second connecting component 120 may also include a handle 123, which is fixedly connected to the end of the first extension 1212 away from the second mounting portion 1221, thereby making it faster and easier to rotate the driving member 121 to drive the driven member 122 to rotate.

[0042] at the same time, Figure 2 As shown, in another embodiment of this application, the second connecting component 120 may further include an anti-slip sleeve 1232, which may be fitted onto the end of the handle 123 away from the drive member 121, thereby not only protecting the handle 123, but also making it more convenient for human operation.

[0043] Please combine Figure 2 And see Figure 4 , Figure 4 for Figure 1 An exploded view of the fixture 100 shown. In some embodiments, such as... Figure 2 and Figure 4 As shown, the fixing device 100 may further include a fixing base 140 and a second connecting member 132. Specifically, the fixing base 140 is disposed on the side of the driving member 121 away from the driven member 122, and the fixing base 140 may include a first limiting plate 141 and a second limiting plate 142, which are spaced apart from each other to form a limiting space 143.

[0044] Please continue to refer to Figure 2 and Figure 4 The driving member 121 may also include a second extension 1213, which extends in the direction toward the first connecting component 110 and is disposed in the limiting space 143. Meanwhile, the second connecting member 132 may pass through the first limiting plate 141, the second extension 1213 and the second limiting plate 142, so that the second extension 1213 is rotatably connected to the fixed base 140.

[0045] It is understandable that since the second extension 1213 is disposed within the limiting space 143 formed by the first limiting plate 141 and the second limiting plate 142, when the second extension 1213 rotates relative to the fixed base 140, the first limiting plate 141 and the second limiting plate 142 can limit the second extension 1213 in the vertical direction, thereby preventing the second extension 1213 from becoming displaced during rotation.

[0046] Meanwhile, it should be noted that the first connecting member 131 and the second connecting member 132 in the embodiments of this application can be a rotating shaft structure, and can be used with bearing 171 and snap ring 172. In this way, not only can the rotation of the driving member 121 relative to the fixed base 140 and the rotation of the driven member 122 relative to the driving member 121 be achieved, but the snap ring 172 can also be provided to prevent the rotating shaft from coming loose during rotation.

[0047] like Figure 2 As shown, when the fixing device 100 is in the engaged state, the fixing device 100 may include a first rotation area 151 and a second rotation area 152 located on the left and right sides of the connecting line formed between the engagement points of the first engagement portion 113 and the second engagement portion 1223 and the first connector 131, and the second connecting component 120 rotates along the direction from the first rotation area 151 to the second rotation area 152 to unlock the fixing device 100, wherein the second connector 132 is located within the second rotation area 152.

[0048] Understandably, when the drive member 121 needs to be rotated to a certain angle to secure the spare tire to the vehicle, the steering force of the drive member 121 will generate a reaction force with the engaging force between the driven member 122 and the first connecting assembly 110. When the second connecting member 132 is located to the right of the connecting line formed between the engaging part of the first engaging part 113 and the second engaging part 1223 and the first connecting member 131, the rotational force and the engaging force can be balanced, thereby achieving the most secure engagement between the driven member 122 and the first connecting assembly 110. It is also understood that because the rotational force and the engaging force are balanced, not only is a secure engagement between the driven member 122 and the first connecting assembly 110 achieved, but the drive member 121 is also secured, thus achieving the goal of stably securing the spare tire to the vehicle via the fixing device 100.

[0049] In some embodiments, such as Figure 4 As shown, the handle 123 may further include a third extension 1231, which is located within the limiting space 143. Simultaneously, the fixing device 100 may also include a third connector 160, which passes through the first limiting plate 141, the third extension 1231, and the second limiting plate 142, and detachably connects the handle 123 to the fixing base 140. This allows the handle 123 and the drive member 121 to be secured to the vehicle after the spare tire is stably fixed using the fixing device 100, further preventing the handle 123 or the drive member 121 from loosening and unlocking the fixing device 100 when encountering bumps during vehicle operation.

[0050] It is understandable that, since the third extension 1231 of the handle 123 is disposed within the limiting space 143, the first limiting plate 141 and the second limiting plate 142 can also limit the vertical direction of the third extension 1231, thereby preventing the third extension 1231 from becoming displaced when encountering vehicle bumps, and further ensuring the reliability of the fixing device 100.

[0051] Please combine Figure 4 And see Figure 5 , Figure 5 for Figure 4 A schematic diagram of the overall structure of the third connector 160 in the fixing device 100 shown.

[0052] Furthermore, such as Figure 4 and Figure 5As shown, in the above embodiment, the third connector 160 may include a housing 161, a pull ring 162, and a limiting member 163. The housing 161 is hollow to form a hollow region. The pull ring 162 is fixedly connected to the limiting member 163. The limiting member 163 is movably disposed within the hollow region and elastically connected to the inner wall of the housing 161, thereby allowing the separation of the third connector 160 from the handle 123 by pulling the pull ring 162. It should be noted that this embodiment does not limit the specific elastic connection method between the limiting member 163 and the inner wall of the housing 161; for example, it can be one of various elastic connection methods such as a spring connection or the use of a rubber ring.

[0053] This application also provides a motorized device 200, please refer to... Figure 6 , Figure 6 This is a partial structural diagram of the motor vehicle 200 provided in an embodiment of this application. The motor vehicle 200 includes a rear door panel 210, a rear bumper 220, and a fixing device 100 mentioned in any of the above embodiments. The rear door panel 210 is used to install a spare tire, the rear bumper 220 is used to connect to the rear door panel 210, and one end of the fixing device 100 is used to connect to the spare tire, and the other end is used to connect to the rear bumper 220. Thus, the fixing device 100 achieves the purpose of ensuring that the spare tire is more stable when encountering bumps during vehicle operation, and avoids the spare tire from becoming loose or even falling off.

[0054] It is understood that the motorized equipment 200 provided in this embodiment can be a motor vehicle such as a pickup truck or a car, or a motorized vessel such as a ship or a yacht. That is, as long as it includes the aforementioned fixed device 100, it can be included in the scope of protection of this application.

[0055] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0056] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.
