Description

Technical Field

[0001] The utility model relates to the technical field of roof luggage locking, in particular to a locking mechanism for a roof luggage. Background Art

[0002] When the vehicle brakes or accelerates emergently, the items in the roof box will move rapidly. The rapid displacement will impact the box body, causing the box opening and posing a great safety hazard. At the same time, when the vehicle is driving at high speed, wind resistance will be generated, which will also force the box to open. In order to reduce the probability of accidents, generally a cover is placed at the front end of the box body, which can not only prevent the items from hitting the box body but also block the wind and reduce the influence of air flow on the box body. Content of the Utility Model

[0003] The purpose of the utility model is to provide a locking mechanism for a roof luggage, which cleverly sets the locking mechanism at the front and rear ends instead of the side of the vehicle body, so that it forms a resistance force itself, blocks the wind, and at the same time can reduce the influence of air flow on the box body.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions.

[0005] The locking mechanism for a roof luggage includes a locking mechanism that is arranged along the vehicle driving direction and is located at the front end of the driving direction to form a driving resistance.

[0006] An unlocking mechanism for controlling the unlocking of the locking mechanism, the unlocking mechanism is located at the side of the vehicle body and is arranged at an angle with the locking mechanism.

[0007] Further, it further includes a reset pause member. When the unlocking mechanism acts on the locking mechanism to unlock it, the reset pause member is forced to bounce up, so that the unlocking action of the locking mechanism is maintained and in an unlocking holding state. When the locking mechanism is subjected to a force, the reset pause member is pressed down, and the unlocking is reset until the locking mechanism returns to the locking state.

[0008] Further, the locking mechanism includes an upper locking mechanism and a lower locking mechanism, and the reset pause member is assembled close to the lower locking mechanism. Under normal conditions, it is pressed below the lower locking mechanism.

[0009] Further, the lower locking mechanism includes a lower locking body forming an assembly shell, and the reset pause member is assembled in the assembly shell through an elastic reset key and is pressed down in a compressed state under normal conditions.

[0010] Further, the unlocking mechanism is linked with an unlocking pull block located in the assembly cavity, and the unlocking pull block drives the lower locking block to rotate, so that the lower locking block presses or releases the reset pause member.

[0011] Further, the lower locking block includes a rotating part and an assembly cavity located below the rotating part for assembling the unlocking pull block.

[0012] Further, a stop block is provided on the reset and pause member. When the reset and pause member is released, the reset and pause member in a compressed state moves in a reset manner, and the stop block contacts the assembly cavity to pause its rotation.

[0013] Further, the unlocking mechanism is linked with the unlocking pull block through an unlocking pull rope passing through the assembly cavity.

[0014] Further, the upper locking mechanism forms a locking hook, and a cavity part through which the locking hook passes is provided on the lower locking mechanism.

[0015] Further, a guiding surface that contacts the reset and pause member is formed inside the locking hook. When a force acts on the locking mechanism, the reset and pause member disengages from the guiding surface and the reset continues.

[0016] Further, it further includes a luggage case located at the top of the vehicle compartment. The locking mechanism is located at the front end and / or the rear end of the luggage case, and the front end is arranged along the vehicle body length direction and is the end close to the vehicle head.

[0017] The beneficial effects of the present utility model are as follows:

[0018] In the present utility model, the locking mechanism is arranged at the front side instead of the side, thereby forming a reverse resistance with the airflow during vehicle driving, enhancing the overall strength and safety. Compared with the locking arranged on the side, it directly forms a head-on collision with the airflow to improve the safety performance.

[0019] Secondly, in the present utility model, the locking mechanism and the unlocking mechanism are arranged at an angle, such as being vertically arranged or obliquely arranged, rather than on the same horizontal line. This kind of arrangement further increases the resistance and improves the safety. Description of the Drawings

[0031] The present utility model will be described in detail below in conjunction with the embodiments shown in the drawings. However, it should be noted that these embodiments are not limitations on the present utility model. Any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present utility model.

[0032] Referring to the attached Figures 1-9 As shown, the locking mechanism 10 for the roof luggage case in this embodiment includes a locking mechanism 10 that is arranged along the vehicle driving direction and is located at the front end in the driving direction to form a driving resistance; an unlocking mechanism 20 for controlling the unlocking of the locking mechanism 10, and the unlocking mechanism 20 is located on the side of the vehicle body and is arranged at an angle to the locking mechanism 10.

[0033] During normal vehicle driving, it is generally moving forward or backward in reverse, that is, the entire driving direction is consistent with the vehicle body length direction. In this embodiment, there are three ways to set the locking mechanism 10. The first is to set it near the vehicle head, which is suitable for the normal forward state at this time, and thus can form a resistance near the vehicle head; the second is to set it at the vehicle tail, which is more suitable for the driving state in reverse at this time, and it forms a resistance opposite to the reverse direction; the third is to set the locking mechanism 10 at both the vehicle head and the vehicle tail, and this setting method has a wider application range.

[0034] In this embodiment, there are at least two ways to arrange the locking mechanism 10 and the unlocking mechanism 20. That is, they are vertically arranged, one is arranged in the vertical direction and the other is arranged in the horizontal direction, and they are connected by a vertical connecting member; the second is to connect the locking mechanism and the unlocking mechanism through an inclined connecting member. This arrangement in different horizontal directions can also generate a certain resistance to improve safety.

[0035] In this embodiment, in order to keep the whole state in the unlocked state all the time instead of resetting immediately after unlocking, a reset pause member 212 is added in this embodiment. When the unlocking mechanism 20 acts on the locking mechanism 10 to unlock it, the reset pause member 212 is forced to bounce up, so that the unlocking action of the locking mechanism 10 is maintained and in the unlocked holding state; when the locking mechanism 10 is subjected to a force, the reset pause member 212 is pressed down to unlock and reset until the locking mechanism 10 returns to the locked state. In this embodiment, the addition of the reset pause member enables the locking mechanism 10 not to reset immediately when it is opened. During use, when acting on the unlocking pull rope once, it drives the box to present an unlocked state and the box remains in the open state all the time; in the prior art, for most boxes, after unlocking, it is still necessary to manually maintain the unlocked and open state, which causes inconvenience in use. However, the addition of the reset pause member in this embodiment enables it to be in the open state for a long time, greatly facilitating the user's operation and improving the user experience.

[0036] For the specific locking mechanism 10, it includes an upper locking mechanism 11 and a lower locking mechanism 12. The reset pause member 212 is assembled near the lower locking mechanism 12 and is normally pressed down below the lower locking mechanism 12. This setting enables the reset pause member 212 to have a certain downward pressure, providing a basis for subsequent resetting and the like.

[0037] Referring to the attached drawings, the lower locking mechanism 21 includes a lower locking body 211 forming an assembly shell. The reset pause member 212 is assembled in the assembly shell through an elastic reset key 217 and is normally pressed down in a compressed state. At this time, due to the existence of the elastic reset key 217, it can be reset subsequently.

[0038] To control unlocking, the unlocking mechanism 20 is linked with an unlocking pull block 213 located in the assembly cavity. The unlocking pull block 213 drives the lower locking block 215 to rotate, so that the lower locking block 215 presses down or releases the reset pause member 212. In this embodiment, the unlocking pull block 213 drives the lower locking block 215 to rotate instead of moving horizontally. During its rotation, the reset pause member 212 located below it can be released and popped up, providing a basis for subsequent reset pause or preventing reset.

[0039] When setting the specific structure, the lower locking block 215 includes a rotating part and an assembly cavity located below the rotating part for assembling the unlocking pull block 213. Actually, the rotating part is a circular tubular cavity structure, and then the bottom of the circular tube is symmetrically extended, and assembly holes are added or reduced at the extended part. The unlocking pull block 213 is assembled into the assembly holes through bolts to achieve linkage. Furthermore, horizontally pulling the unlocking pull block can drive rotation and release the reset pause part 212.

[0040] In order to more stably achieve pause reset subsequently, a stop block 2121 is provided on the reset pause part 212. When the reset pause part 212 is released, the reset pause part in the compressed state performs a reset movement, and the stop block 2121 contacts the assembly cavity in the lower locking block, causing the lower locking block to pause rotation, thereby achieving its reset.

[0041] For the convenience of operation, an unlocking pull rope 214 linked to the unlocking pull block 213 is provided. Specifically, the unlocking mechanism is linked to the unlocking pull block through the unlocking pull rope passing through the assembly cavity. Furthermore, by controlling the unlocking pull rope, the control of the unlocking pull block can be achieved.

[0042] Regarding the locking of the locking mechanism 10, specifically, the upper locking mechanism 11 forms a locking hook, and a cavity part through which the locking hook 1111 passes is provided on the lower locking mechanism 21. During the up and down movement of the upper locking mechanism 11, it enters or exits the cavity part, especially the locking hook 1111 passes through the cavity part.

[0043] In this embodiment, a guiding surface in contact with the reset pause part 212 is formed inside the locking hook 1111. When the locking mechanism 10 is subjected to a force, the reset pause part 212 disengages from the guiding surface and the reset continues. In this embodiment, the guiding surface is cleverly utilized to achieve the final reset.

[0044] The assembly method in this embodiment is as follows:

[0045] In the unlocking mechanism, the lower locking block 215 is rotatably connected to the lower locking body 211 to facilitate subsequent rotation control for unlocking; the unlocking pull block 213 is rotatably connected to the lower locking block 215 and slides inside the lower locking body 211. The unlocking pull rope 214 is fixed to the unlocking pull block 213, and the unlocking pull rope 214 is fixed to the unlocking operating part 311. Furthermore, the entire control can be achieved by controlling the unlocking operating part 311; the unlocking pause part 212 slides inside the lower locking body 211, providing a basis for subsequent sliding to achieve pause reset, and the lower locking rear cover 216 is fixed to the lower locking body 211 to form an integral body.

[0046] The working principle in this embodiment is as follows:

[0047] In this embodiment, when setting, the position of the locking mechanism 10 is set in front A or behind B in the vehicle traveling direction, so that the upper cover 1 and the lower cover 2 of the roof box can be locked to each other. The unlocking operating member 311 is arranged on the left side E or the right side F of the roof box, so that it is in different horizontal positions;

[0048] This embodiment mainly includes three major parts, namely, the upper locking assembly 11 fixed on the upper cover 1 of the roof box, the lower locking assembly 21 fixed on the lower cover 2 of the roof box, and the unlocking operating member 311 arranged at E or F; the upper locking assembly 11 includes an upper locking connecting member 112 and an upper locking hook 111; the lower locking assembly 21 mainly includes a lower locking body 211, a reset and pause member 212, an unlocking pull block 213, an unlocking pull rope 214, a lower locking block 215, and a lower locking rear cover 216.

[0049] During assembly, the upper locking hook 111 is inserted into the lower locking body 211, and the lower locking block 215 hooks the upper locking hook 111 to lock the upper cover 1 and the lower cover 2 to each other; by pulling the unlocking operating member 311, the unlocking pull block 213 drives the lower locking block 215 to rotate away from the upper locking hook 111. At the same time, the reset and pause member 212 pops up and uses the inclined plane feature C (i.e., the stop block 2121) to force the lower locking block 215 to maintain a non-return pause state. At this time, the upper locking hook 111 can be disengaged from the locking body 211 to achieve unlocking. During the disengagement process, the inclined plane D on the body of the upper locking hook 111 impacts the unlocking pause member 212 and forces 212 to move downward. At this time, the lower locking block 215 returns from the pause state to the original state.

[0050] In this embodiment, by cleverly using the locking mechanism and unlocking mechanism settings at different positions, the overall resistance resistance is improved, which is more suitable for the roof luggage case and improves the user experience.
