Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and in particular to a side panel safety lock structure. Background Art

[0002] As consumer spending rises, market demand for mid-to-large vehicles continues to grow, and so too do the collision safety requirements for these vehicles. Currently, in the C-NCAP / C-IASI side impact tests, some mid-to-large vehicles with longer wheelbases experience a situation where the lower and rear edges of the side impact barrier barely cover the sill beam and C-pillar. This prevents the C-pillar from effectively bearing the impact load, leading to structural failure. This creates a significant risk of the rear door shifting significantly during a side impact, potentially even sliding into the passenger compartment, seriously impacting rear occupant safety. To address the significant risk of the rear door shifting significantly during a side impact, potentially impacting rear occupant safety, caused by the lower and rear edges of the side impact barrier failing to cover the sill beam and C-pillar in the C-NCAP / C-IASI side impact tests, an anti-slip structure has been introduced. In a side impact, multiple connections between the rear door and the side panel are designed, including door locks and anti-slip structures. This prevents the rear door from pulling away and flipping during impact, effectively protecting occupants in the event of a collision.

[0003] However, the rear door with an anti-slip structure is not easy to open after a collision, which affects rescue and increases the difficulty and risk of passengers escaping from the cabin to a certain extent. Therefore, a new structure is needed to solve this problem. Summary of the Invention

[0004] The object of the present invention is to provide a side panel safety lock structure to solve the problems raised in the above background technology.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A side panel safety lock structure, comprising:

[0007] An anti-slip lock, comprising an anti-slip lock hook, an anti-slip lock column, and a mounting base, wherein one end of the anti-slip lock hook is connected to one end of the anti-slip lock column, the other end of the anti-slip lock column is connected to the mounting base, and the mounting base is connected to the rear door inner panel;

[0008] an anti-slip sleeve, the anti-slip sleeve being positioned opposite to the anti-slip lock, the anti-slip sleeve comprising a lock sleeve body and a lock sleeve base, the lock sleeve body being disposed on the lock sleeve base, the lock sleeve body being provided with an anti-lock lock hole, the lock sleeve body being provided with an anti-slip lock tongue, the anti-slip lock tongue being spaced apart from the lock sleeve body to form an anti-slip lock hole, the anti-slip lock hole being in communication with the anti-lock lock hole, and the lock sleeve base being connected to the lower side of the side panel;

[0009] Under normal conditions, the anti-slip lock and the anti-slip sleeve are loosely matched, and the rear door can be used normally; under collision conditions, the rear door collapses due to side impact, causing the anti-slip lock to displace and / or rotate, and the anti-slip lock hook and the anti-slip lock column are in contact and deformed with the lock sleeve body and the anti-slip lock tongue in the anti-slip lock hole to form an interlock, so that the rear door will not be pulled off and flipped over; during the rescue process after a side collision, the anti-slip lock hook and the anti-slip lock column are pushed from the anti-slip lock hole into the anti-lock lock hole, and the anti-slip lock hook and the anti-slip lock column are unlocked and released from the lock sleeve body and the anti-slip lock tongue, so that the rear door can be opened.

[0010] Optionally, a diameter of the anti-slip lock hook is larger than a diameter of the anti-slip lock column.

[0011] Optionally, the anti-slip lock hook and the anti-slip lock column are coaxially arranged.

[0012] Optionally, the mounting base is provided with a first mounting hole.

[0013] Optionally, the diameters of the anti-slip lock hook and the anti-slip lock column are both smaller than the width of the anti-slip lock hole.

[0014] Optionally, there are two anti-lock lock holes, one of which is located above the anti-slip lock tongue, and the other anti-lock lock hole is located below the anti-slip lock tongue.

[0015] Optionally, the diameters of the anti-slip lock hook and the anti-slip lock column are both smaller than the width of the anti-lock lock hole.

[0017] Beneficial effects of the present invention:

[0018] The side panel safety lock structure provided by the present invention has an installation base connected to the rear door inner panel, and a lock sleeve base connected to the lower side of the side panel. Under normal conditions, the anti-slip lock and the anti-slip sleeve are clearance-matched, and the rear door is used normally, ensuring normal opening and closing of the rear door; under collision conditions, the rear door collapses due to side impact, causing the anti-slip lock to displace and / or rotate, and the anti-slip lock hook and the anti-slip lock column are contacted and deformed with the lock sleeve body and the anti-slip lock tongue in the anti-slip lock hole to form an interlocking, so that the rear door will not be pulled off and flipped, achieving the purpose of protecting the safety of the occupants in the event of a collision; during the rescue process after a side collision occurs, the anti-slip lock hook and the anti-slip lock column are inserted from the anti-slip lock hole into the anti-lock lock hole, and the anti-slip lock hook and the anti-slip lock column are unlocked and released from the lock sleeve body and the anti-slip lock tongue, so that the rear door can be opened, without affecting the rescue and the occupants' escape from the cabin, thereby improving the side collision safety performance and ensuring the safety of the rear passengers. This side safety lock structure can not only prevent the rear door from being severely displaced and sliding into the passenger compartment during a side collision, but also ensure that the rear door is easy to open after a side collision without affecting rescue and passengers' escape from the cabin, thereby improving side collision safety performance and ensuring the safety of rear passengers.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0036] like Figures 1 to 9 As shown, the present invention provides a side panel safety lock structure, including an anti-slip lock 100 and an anti-slip sleeve 200. Among them, the anti-slip lock 100 includes an anti-slip lock hook 110, an anti-slip lock column 120 and a mounting base 130, one end of the anti-slip lock hook 110 is connected to one end of the anti-slip lock column 120, the other end of the anti-slip lock column 120 is connected to the mounting base 130, and the mounting base 130 is connected to the rear door inner panel; the anti-slip cover 200 is positioned opposite to the anti-slip lock 100, the anti-slip cover 200 includes a lock cover body 210 and a lock cover base 220, the lock cover body 210 is set on the lock cover base 220, the lock cover body 210 is provided with an anti-lock lock hole 230, the lock cover body 210 is provided with an anti-slip lock tongue 240, the anti-slip lock tongue 240 and the lock cover body 210 are spaced apart to form an anti-slip lock hole 250, the anti-slip lock hole 250 is communicated with the anti-lock lock hole 230, and the lock cover base 220 is connected to the lower side of the side panel. Under normal conditions, the anti-slip lock 100 and the anti-slip sleeve 200 are loosely matched, and the rear door can be used normally; under collision conditions, the rear door collapses due to side impact, causing the anti-slip lock 100 to displace and / or rotate, and the anti-slip lock hook 110 and the anti-slip lock column 120 are in contact and deformed with the lock sleeve body 210 and the anti-slip lock tongue 240 in the anti-slip lock hole 250 to form an interlocking, so that the rear door will not be pulled off and flipped; during the rescue process after the side collision occurs, the anti-slip lock hook 110 and the anti-slip lock column 120 are inserted from the anti-slip lock hole 250 into the anti-lock lock hole 230, and the anti-slip lock hook 110 and the anti-slip lock column 120 are unlocked and released from the lock sleeve body 210 and the anti-slip lock tongue 240, so that the rear door can be opened.

[0037] The side panel safety lock structure provided by the present invention has a mounting base 130 connected to the rear door inner panel, and a lock sleeve base 220 connected to the lower side of the side panel. In a normal state, the anti-slip lock 100 and the anti-slip sleeve 200 are loosely matched, and the rear door is used normally to ensure normal opening and closing of the rear door. In a collision state, the rear door collapses due to a side impact, causing the anti-slip lock 100 to displace and / or rotate, and the anti-slip lock hook 110 and the anti-slip lock column 120 are in the anti-slip lock hole 250 and the lock sleeve body 210 and the anti-slip lock tongue 240. Contact deformation occurs to form an interlock, so that the rear door will not be pulled off and flipped, thereby protecting the safety of the occupants in a collision; during the rescue process after a side collision occurs, the anti-slip lock hook 110 and the anti-slip lock column 120 are inserted from the anti-slip lock hole 250 into the anti-lock lock hole 230, and the anti-slip lock hook 110 and the anti-slip lock column 120 are unlocked and released from the lock sleeve body 210 and the anti-slip lock tongue 240, so that the rear door can be opened, without affecting the rescue and the occupants' escape from the cabin, thereby improving the side collision safety performance and ensuring the safety of the rear passengers.

[0038] In some embodiments, the diameter of the anti-slip lock hook 110 is larger than the diameter of the anti-slip lock post 120, allowing the anti-slip lock hook 110 to interlock with the lock sleeve body 210 or the anti-slip lock tongue 240 in the event of a collision. The anti-slip lock hook 110 and the anti-slip lock post 120 are coaxially arranged to ensure that, under normal conditions, the anti-slip lock 100 and the anti-slip sleeve 200 have a clearance fit, maintaining a safe distance between the anti-slip lock 100 and the anti-slip sleeve 200 during both static and relative motion, without interference. The diameters of both the anti-slip lock hook 110 and the anti-slip lock post 120 are smaller than the width of the anti-slip lock hole 250, allowing them to smoothly pass through the anti-slip lock hole 250 under normal conditions.

[0039] The mounting base 130 defines a first mounting hole 131, through which the anti-slip lock 100 is fixed to the rear door inner panel. The number of the first mounting holes 131 can be two or more, and the two first mounting holes 131 are located on both sides of the anti-slip lock column 120.

[0040] In some embodiments, there are two anti-lock lock holes 230, one located above the anti-slide lock tongue 240, and the other located below the anti-slide lock tongue 240. During rescue after a side collision, the anti-slide lock hook 110 and the anti-slide lock column 120 are forced upward or downward through the anti-slide lock hole 250 to slide upward or downward into the anti-lock lock hole 230. The anti-slide lock hook 110 and the anti-slide lock column 120 are unlocked from the lock sleeve body 210 and the anti-slide lock tongue 240, allowing the rear door to be opened without affecting rescue and occupant escape from the cabin, thereby improving side collision safety and ensuring the safety of rear passengers.

[0041] The diameters of the anti-slip lock hook 110 and the anti-slip lock column 120 are both smaller than the width of the anti-lock lock hole 230, ensuring that the anti-slip lock hook 110 and the anti-slip lock column 120 can be smoothly disengaged from the anti-lock lock hole 230 during the rescue process after a side collision occurs.

[0042] The lock sleeve base 220 has a second mounting hole 221, and the anti-slip cover 200 is fixed to the lower side of the side panel through the second mounting hole 221 on the lock sleeve base 220. The number of the second mounting holes 221 can be two or more, and the two second mounting holes 221 are respectively located on both sides of the lock sleeve body 210.

[0043] The usage scenarios of the side panel safety lock structure provided by the present invention are described as follows:

[0044] like Figure 4 and Figure 5 As shown, usage scenario one: for daily car use, the car door is opened and closed normally. In this scenario, the anti-slip lock 100 and the anti-slip cover 200 are clearance-matched. The anti-slip lock 100 and the anti-slip cover 200 maintain a safe distance during static and relative motion without interference.

[0045] like Figure 6 and Figure 7 As shown, usage scenario two: in the process of side collision, in this scenario, the rear door collapses due to the side impact, causing the anti-slip lock 100 to displace and / or rotate, and the anti-slip lock hook 110 and the anti-slip lock column 120 contact and deform with the lock sleeve body 210 and the anti-slip lock tongue 240 in the anti-slip lock hole 250 to form an interlocking, so that the rear door will not be pulled off and flipped, thereby achieving the purpose of protecting the safety of the occupants in the event of a collision.

[0046] like Figure 8 and Figure 9 As shown, usage scenario three: for the rescue process after a side collision occurs, in this scenario, personnel inside or outside the passenger compartment need to apply an upward or downward force to the position of the side safety lock structure. The applied force is calculated to be 30N, and the anti-slip lock hook 110 and the anti-slip lock column 120 will be moved upward or downward from the anti-slip lock hole 250 into the anti-lock lock hole 230. The anti-slip lock hook 110 and the anti-slip lock column 120 are unlocked and released from the lock sleeve body 210 and the anti-slip lock tongue 240. The anti-slip lock hook 110 and the anti-slip lock column 120 can be smoothly disengaged from the anti-lock lock hole 230, ensuring that the rear door is easy to open after a side collision, without affecting the rescue and the passengers' escape from the cabin, thereby improving the side collision safety performance and ensuring the safety of the rear passengers.

[0047] This side safety lock structure can not only prevent the rear door from being severely displaced and sliding into the passenger compartment during a side collision, but also ensure that the rear door is easy to open after a side collision without affecting rescue and passengers' escape from the cabin, thereby improving side collision safety performance and ensuring the safety of rear passengers.
