[0020] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] The following combination Figure 1 and Figure 2 The utility model describes a vehicle door lock body side impact protection device and a vehicle door.
[0022] like Figure 1 As shown, in an embodiment of the present invention, the vehicle door lock body side impact protection device includes a buffer block 50, which is used to be arranged on the side of the vehicle door lock body 30 facing the vehicle door outer panel 40, or to be arranged between the vehicle door outer panel 40 and the reinforcement plate 20, and the buffer block 50 is a flexible buffer block.
[0023] Specifically, if Figure 2 As shown, the vehicle door comprises: a door inner panel 10, a reinforcement plate 20, a door lock body 30, and a door outer panel 40. The reinforcement plate 20 is welded to the door inner panel 10, the door inner panel 10 and the door outer panel 40 are welded together, and the door lock body 30 is connected to the reinforcement plate 20. In this embodiment, a buffer block 50 is provided on the side of the door lock body 30 facing the door outer panel 40. When the door outer panel 40 is impacted, the door outer panel 40 deforms and compresses the buffer block 50, rather than directly compressing the door lock body 30. This prevents the door lock body 30 from failing and causing the door to open automatically.
[0024] Optionally, a cavity is formed between the reinforcing plate 20 and the door outer panel 40, and a buffer block 50 may be disposed within the cavity. When the door outer panel 40 collides, the buffer block 50 acts as a buffer to prevent the door lock body 30 from being deformed by compression, thereby causing the door lock body 30 to fail and automatically open the door.
[0025] Furthermore, in an embodiment of the present invention, the buffer block 50 is a flexible buffer block, and the material of the buffer block 50 can be foam, plastic, rubber, etc.
[0026] The vehicle door lock body side impact protection device provided by the embodiment of the present invention can play a buffering role when the vehicle door outer panel collides by arranging a buffer block on one side of the vehicle door lock body, or arranging a buffer block between the vehicle door outer panel and the reinforcement plate, thereby preventing the vehicle door lock body from being squeezed and deformed, thereby ensuring the normal opening and closing of the vehicle door lock body, avoiding the vehicle door lock body from failing and throwing people inside the vehicle out, and improving driving safety.
[0027] In the embodiment of the present invention, the buffer block 50 can be rectangular, regardless of whether it is positioned on one side of the door lock body 30 or between the door outer panel 40 and the reinforcement plate 20. When the door outer panel 40 is impacted, causing deformation of the sheet metal of the door outer panel 40, the buffer block 50, with its sufficient surface area, can cushion the deformation, thereby preventing the door lock body 30 from being squeezed and deformed.
[0028] Furthermore, the buffer block 50 should have a certain thickness to buffer the deformation of the door outer panel 40. Optionally, in an embodiment of the present invention, the thickness of the buffer block 50 is greater than or equal to 7 mm.
[0029] When the buffer block 50 is disposed on one side of the door lock body 30 , the buffer block 50 is disposed in contact with the surface of the door lock body 30 close to the door outer panel 40 . At this time, the surface area of the buffer block 50 is larger than the surface area of the surface.
[0030] Specifically, when the buffer block 50 is fitted with the surface of one side of the door lock body 30, the width and length of the buffer block 50 should be greater than the width and length of the surface fitted with the door lock body 30, so that when the door outer panel 40 is deformed, the extrusion force is transmitted to the buffer block 50 and cannot directly act on the door lock body 30, thereby protecting the door lock body 30.
[0031] Furthermore, when the buffer block 50 is disposed on one side of the door lock body 30 , the buffer block 50 can be disposed in various ways, such as: the buffer block 50 can be clamped to two opposite surfaces of the door lock body 30 ; or, it can be clamped to two adjacent surfaces of the door lock body 30 .
[0032] Specifically, the surface of the door lock body 30 facing the door outer panel 40 is defined as the first surface, the surface of the door lock body 30 connected to the reinforcement plate 20 is defined as the second surface, and the surface opposite the second surface is defined as the third surface. In other words, the buffer block 50 can be engaged with the second and third surfaces, or it can be bonded to the first and third surfaces.
[0033] Specifically, if Figure 1 As shown, Figure 1The present invention provides a buffer block structure. The buffer block 50 comprises a first body 51, a second body 52, and a third body 53, which are sequentially connected. The first body 51 and the third body 53 are arranged parallel to each other on either side of the second body 52. The first body 51 and the third body 53 are respectively configured to engage with two opposing surfaces of the door lock body 30. Specifically, the first body 51 overlaps the second surface, the second body 52 abuts the first surface, and the third body 53 overlaps the third surface, thereby wrapping the surface of the door lock body 30 facing the door outer panel 40. When the door outer panel 40 collides, the buffer block 50 completely wraps the surface of the door lock body 30 facing the door outer panel 40, thereby protecting the door lock body 30 from being squeezed and deformed.
[0034] In the above-described embodiment, the first body 51 , the second body 52 and the third body 53 form a U-shaped structure.
[0035] When the buffer block 50 is in contact with the first and third surfaces of the door lock body 30 , the buffer block 50 includes a fourth body and a fifth body connected thereto. The fourth body and the fifth body are arranged vertically, and the fourth body and the fifth body are respectively used to be in contact with the two adjacent surfaces of the door lock body 30 .
[0036] That is, in this embodiment, the buffer block 50 is L-shaped, the fourth body of the buffer block 50 is in contact with the first surface of the door lock body 30, and the fifth body of the buffer block 50 overlaps the third surface of the door lock body 30. When the door outer panel 40 collides, the fourth body can protect the door lock body 30.
[0037] The vehicle door lock body side impact protection device provided by the embodiment of the present invention can wrap the surface of the vehicle door lock body facing the vehicle door outer panel by setting the structure of the buffer block to a U-shaped structure or an L-shaped structure. When the vehicle door outer panel collides, the buffer block can buffer the entire surface of the vehicle door lock body facing the vehicle door outer panel, thereby preventing the vehicle door lock body from being squeezed and deformed.
[0038] In the above-described embodiment, the buffer block 50 is connected to the door lock body 30 by bonding. Arranging the buffer block 50 in a U-shaped or L-shaped structure provides a larger bonding area between the buffer block 50 and the door lock body 30 than a rectangular block structure, making the bonding more secure and less likely to fall off.
[0039] The vehicle door lock body side impact protection device provided by the embodiment of the present invention increases the area when the buffer block is bonded to the vehicle door lock body and improves the bonding strength by setting the structure of the buffer block to a U-shaped structure or an L-shaped structure; at the same time, setting the buffer block to a U-shaped structure allows the buffer block to be clamped on two opposite surfaces of the vehicle door lock body, further improving the bonding strength and making it less likely to fall off.
[0040] Furthermore, during assembly, the buffer block 50 may be installed on the door lock body 30 first, and then the door lock body 30 may be installed on the reinforcement plate 20 to reduce the difficulty of installation.
[0041] When the buffer block 50 is disposed between the door outer panel 40 and the reinforcement plate 20, the buffer block 50 can be disposed on the reinforcement plate 20, with a gap therebetween, or the buffer block 50 can be in close contact with the door outer panel 40. When the buffer block 50 is in close contact with the door outer panel 40, the gap between the reinforcement plate 20 and the door outer panel 40 is filled. When the door outer panel 40 collides with the vehicle, the buffer block 50 can cushion the deformation of the door outer panel 40, thereby preventing the door outer panel 40 from undergoing significant deformation, protecting the door outer panel 40, and further preventing the door lock body 30 from deforming.
[0042] In an embodiment of the present invention, the buffer block 50 may be made of foam, plastic or rubber. In one embodiment of the present invention, the buffer block 50 is made of EPDM rubber.
[0043] When the vehicle door lock body side impact protection device provided by an embodiment of the present invention was applied to a vehicle door, a national standard Beta lock with a static strength of 2.0 times was selected. A buffer block 50 was installed on one side of the Beta lock. A side impact test was conducted, in which the colliding vehicle weighed 1.4 tons and was traveling at a speed greater than or equal to 60 km / h. After the collision, the vehicle door remained intact, the door lock body 30 remained intact, and the buffer block 50 was severely damaged by compression. The test demonstrated that the vehicle door lock body side impact protection device provided by an embodiment of the present invention can effectively protect the door lock body 30 from damage and failure when the door outer panel 40 is impacted, thereby improving driving safety.
[0044] like Figure 2 As shown, an embodiment of the present invention further provides a vehicle door, comprising: a door inner panel 10, a reinforcement plate 20, a door lock body 30, a door outer panel 40, and a door lock body side impact protection device. The reinforcement plate 20 is welded to the door inner panel 10, the door inner panel 10 is welded to the door outer panel 40, and the door lock body 30 is connected to the reinforcement plate 20. A cavity is defined between the reinforcement plate 20 and the door outer panel 40, and the door lock body side impact protection device is disposed on one side of the door lock body 30 or within the cavity.
[0045] Specifically, the door lock body side impact protection device includes a flexible buffer block 50, which is positioned on the side of the door lock body 30 facing the door outer panel 40, or between the door outer panel 40 and the reinforcement plate 20. Positioning the buffer block 50 on one side of the door lock body 30 allows the outer panel 40 to deform during a collision, squeezing the buffer block 50 rather than directly squeezing the door lock body 30. This prevents the door lock body 30 from failing and causing the door to open automatically.
[0046] Optionally, a buffer block 50 may be disposed in the cavity. When the door outer panel 40 collides, the buffer block 50 acts as a buffer against compression, thereby preventing the door lock body 30 from being deformed by compression, thereby rendering the door lock body 30 ineffective and automatically opening the door.
[0047] Furthermore, in an embodiment of the present invention, the buffer block 50 is a flexible buffer block, and the material of the buffer block 50 can be foam, plastic, rubber, etc.
[0048] The vehicle door provided by the embodiment of the present invention, by providing a vehicle door lock body side impact protection device, can play a buffering role when a collision occurs in the vehicle door outer panel, preventing the vehicle door lock body from being squeezed and deformed, thereby ensuring the normal opening and closing of the vehicle door lock body, avoiding the vehicle door lock body from failing and throwing people out of the vehicle, and improving driving safety.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
