[0032] Figures 1 to 5 FIG. 1 is a schematic diagram showing the structure of a door lock structure provided by an embodiment of the utility model. Figures 1 to 5 As shown, the first embodiment of the utility model provides a vehicle door lock structure, including a vehicle door handle frame 1, a lock core pull rod 2 and a vehicle door lock assembly 3 connected in sequence, a vehicle door handle 20 is installed on the outer side of the vehicle door handle frame 1, a baffle 4 is provided on the inner top of the vehicle door handle frame 1, a protective cover 5 is provided on the side of the lock core pull rod 2 close to the vehicle door, and the top of the protective cover 5 has a first connecting flange 51 extending toward the vehicle door handle frame 1, the first connecting flange 51 is located below the baffle 4, and at least partially overlaps with the baffle 4 in upper and lower directions.

[0033] The door handle frame 1, the lock cylinder rod 2 and the door lock assembly 3 are connected in sequence from top to bottom from the outside of the door to the inside of the door. A baffle 4 is arranged on the top of the inner side of the door handle frame 1 to block the gap between the door and the door handle frame 1, preventing hook-shaped tools such as iron hooks from hooking the lock cylinder rod 2 from above the door handle 20 to unlock the door.

[0034] One end of the lock core rod 2 is connected to the door handle frame 1, and the other end of the lock core rod 2 is connected to the door lock assembly 3. A protective cover 5 is set on the inner side of the lock core rod 2 (the side of the lock core rod 2 close to the door), and the lock core rod 2 (including other parts of the connection between the lock core rod 2 and the door handle frame 1 and the connection between the lock core rod 2 and the door lock assembly 3) is located in the protective cover 5 to protect the lock core rod 2. A first connecting flange 51 extending toward the door handle frame 1 is provided on the top of the protective cover 5. The first connecting flange 51 is located below the baffle plate 4 and can protect the lock cylinder rod 2 and the components at the connection between the lock cylinder rod 2 and the door handle frame 1 from above the lock cylinder rod 2. The first connecting flange 51 and the baffle plate 4 at least partially overlap with each other up and down. At the same time as the baffle plate 4 is used to perform the first level of protection for the door lock, the first connecting flange 51 below the baffle plate 4 can be used to perform the second level of protection for the door lock, thereby effectively preventing the lock cylinder rod 2 from being hooked from above the door handle 20 by hook-shaped tools such as iron hooks.

[0035] The vehicle door lock structure provided in this embodiment is achieved by configuring the vehicle door lock to include a vehicle door handle frame 1, a lock core rod 2 and a vehicle door lock assembly 3 which are connected in sequence. A vehicle door handle 20 is installed on the outer side of the vehicle door handle frame 1, a baffle plate 4 is provided on the inner top of the vehicle door handle frame 1, a protective cover 5 is provided on the side of the lock core rod 2 close to the vehicle door, and the top of the protective cover 5 has a first connecting flange 51 extending toward the vehicle door handle frame 1. The first connecting flange 51 is located below the baffle plate 4 and at least partially overlaps with the baffle plate 4 in upper and lower directions. Double protection can be formed by using the baffle plate 4 and the first connecting flange 51 of the protective cover 5 to block the gap between the vehicle door and the vehicle door handle frame 1, prevent hook-shaped tools such as iron hooks from hooking the lock core rod 2 from above the vehicle door handle 20, unlock the vehicle door, improve the vehicle anti-theft performance, and prevent the vehicle from being stolen.

[0036] The purpose of vehicle anti-theft performance is to determine whether the vehicle anti-theft system installed as standard can prevent the vehicle from being forced into the vehicle within 2 minutes, prevent the steering lock from being forced to be released within 2 minutes, and whether the electronic anti-theft system can resist cracking within 5 minutes. Vehicle anti-theft performance can be broken down into three parts: body safety, electronic safety, and vehicle identification. The above door lock structure can effectively ensure the safety of the vehicle body.

[0037] In particular, the above-mentioned door lock structure can meet the vehicle anti-theft performance of the British market and complies with the SEC-C4NVSA2019Criteria. The vehicle anti-theft rating (NVSA rating) refers to the evaluation level used to evaluate the anti-theft performance of the entire vehicle. The British Thatcham company distinguishes the vehicle anti-theft level with English letters, and divides it into four levels from good to bad: E, A, D, and U, respectively representing: E-exceeds safety requirements, A-meets safety requirements, D-does not meet safety requirements, and U-unacceptable.

[0038] In this embodiment, the baffle 4 is a horizontal baffle, which can effectively block the gap between the vehicle door and the door handle frame 1, and has a small size and a light weight. In other embodiments, the baffle 4 can also be an inclined baffle.

[0039] In some embodiments, Figure 4 As shown, there is a gap 6 between the first connecting flange 51 and the baffle 4, and the gap 6 is less than or equal to 2 mm.

[0040] The gap 6 is the safe assembly distance between the top of the protective cover 5 and the baffle 4, which avoids interference problems during installation due to component tolerances. At the same time, setting the size of the gap 6 to be less than or equal to 2 mm can prevent a large gap from being generated between the first connecting flange 51 and the baffle 4, and prevent the use of hook-shaped tools such as iron hooks to extend into the gap to hook the lock core rod 2, thereby further ensuring the safety of the door lock.

[0041] In some embodiments, Figure 4 As shown, the overlapping length L between the first connecting flange 51 and the baffle 4 is greater than or equal to 20 mm, which can effectively prevent the protective cover 5 from being pried open by a hook-shaped tool, causing the door lock function to fail.

[0042] In some embodiments, Figure 3 As shown, the side of the protective cover 5 has a second connecting flange 52 extending toward the door handle frame 1 , a clamping piece 53 is provided at the end of the second connecting flange 52 , and a clamping position for clamping with the clamping piece 53 is provided on the door handle frame 1 .

[0043] The second connecting flange 52 is used to align the lock cylinder pull rod 2 from the side of the lock cylinder pull rod 2, and a clamping member 53 is provided at the end of the second connecting flange 52, and the clamping member 53 is clamped to the clamping position on the door handle frame 1, so that the protective cover 5 can be reliably connected to the door handle frame 1 and the assembly tolerance between the two can be reduced.

[0044] In this embodiment, a second connecting flange 52 is respectively provided on the left and right sides of the protective cover 5, and a clamping part 53 is respectively provided on the upper and lower sides of the end of the second connecting flange 52, which can improve the stability and reliability of the connection between the protective cover 5 and the door handle frame 1, prevent the protective cover 5 from falling off, and ensure the safety of the door lock.

[0045] In some embodiments, Figure 1 and Figure 3As shown, a reinforcing rib 7 is provided at the connection between the door handle frame 1 and the baffle 4, one end of the reinforcing rib 7 is connected to the door handle frame 1, and the other end of the reinforcing rib 7 is connected to the baffle 4, which can improve the connection strength between the baffle 4 and the door handle frame 1, as well as the structural strength of each, and in particular, can strengthen the strength of the bottom of the baffle 4 to prevent attacks from the water shear direction. In a specific implementation, multiple reinforcing ribs 7 can be arranged at intervals along the length direction of the baffle 4 for effective reinforcement.

[0046] Optionally, the reinforcing rib 7 is a triangular rib plate, a trapezoidal rib plate or an L-shaped rib plate. The triangular rib plate and the trapezoidal rib plate have good supporting stability, and can effectively improve the connection strength between the baffle 4 and the door handle frame 1, and improve the bottom strength of the baffle 4. The L-shaped rib plate can also improve the connection strength between the baffle 4 and the door handle frame 1, as well as the bottom strength of the baffle 4, but the length of the two plates of the L-shaped rib plate may need to be set longer to increase the connection area with the baffle 4 and the door handle frame 1 to ensure connection reliability.

[0047] The reinforcing ribs 7 may also be ribs, such as L-shaped ribs. When the reinforcing ribs 7 are ribs, more ribs may be needed to effectively improve the connection strength between the baffle 4 and the door handle frame 1 and improve the bottom strength of the baffle 4.

[0048] In some embodiments, a metal protective bracket 8 is further provided on the inner side of the door handle frame 1, the metal protective bracket 8 is connected to the door handle frame 1, and is located in a protective space formed by the door handle frame 1 and the protective cover 5. A lock core cam shaft 202 is provided on the inner side of the door handle 20, and the metal protective bracket 8 is arranged around the lock core cam shaft 202.

[0049] like Figure 2 , Figure 3 and Figure 5 As shown, a lock core 201 is installed on the door handle 20, and the lock core 201 is connected to one end of the lock core pull rod 2 through the lock core cam shaft 202, and the other end of the lock core pull rod 2 is connected to the door lock assembly 3. In the prior art, by using tools such as a hammer and a screwdriver to pull the lock core 201 up, down, left, and right on the side of the door lock, the door lock can be forcibly impacted from the side, causing the door lock to fail (the door lock assembly 3 is unlocked). The metal protection bracket 8 is arranged around the lock core cam shaft 202 of the lock core 201, which can prevent the screwdriver from being inserted from the junction of the door handle 20 and the door panel, contacting the lock core cam shaft 202, and unlocking by prying up and down, that is, the metal protection bracket 8 can prevent the door lock from being forcibly impacted from the side of the door to be forcibly unlocked, and cooperate with the above-mentioned baffle 4 and protective cover 5 to protect the upper part of the door lock, it can realize multi-directional protection of the door lock, and further improve the anti-theft performance of the door. The metal protection bracket 8 can be connected to the door handle frame 1 through fasteners such as bolts 9 to improve the bracket strength.

[0050] In some embodiments, the metal protective bracket 8 is a plate bracket having a plate thickness of 1 mm to 1.5 mm, which effectively protects the door lock from impact while reducing the overall weight of the door lock.

[0051] Furthermore, the metal protective bracket 8 is preferably a galvanized plate bracket, which can improve the anti-rust performance of the bracket and extend its service life.

[0052] like Figure 5 As shown, in this embodiment, the above-mentioned door lock structure is installed between the door outer panel 30 and the door inner panel, and the door handle frame 1 is closely connected to the door outer panel 30, so that the door handle frame 1 can be reliably fixed to the door outer panel 30, avoiding damage to the door handle frame 1 caused by prying the lock core 201, thereby improving the reliability of the entire door lock structure.

[0053] In order to better ensure the fit between the door handle frame 1 and the door outer panel 30, as Figure 2 and Figure 5 As shown, the length H (along the vehicle height direction, Z direction) of the door handle frame 1 is set to be greater than or equal to 120 mm, and the width W (along the vehicle length direction, X direction) is set to be greater than or equal to 70 mm, so as to further prevent the lock core 201 of the door handle 20 from being pried up and down by the screwdriver, thereby prying up the lock core rod 2 to open the door.

[0054] The material of the door handle frame 1 is preferably PA6-GF30, which is a kind of engineering plastics, also called nylon 6, and contains 30% reinforced glass fiber, and can be effectively bonded to the door outer panel 30.

[0055] A second embodiment of the utility model provides a vehicle including the above-mentioned door lock structure.
