A rear door panel locking mechanism includes:

[0029] Carriage 1, with a rear door panel 2 provided on one side;

[0030] A first mounting base 3 is connected to one side of the bottom of the carriage 1. A support arm 4 is rotatably connected to one side of the first mounting base 3 via a rotating shaft. A push rod 5 is rotatably connected to one side of the support arm 4 via a rotating shaft. A handle 8 is connected to one end of the support arm 4.

[0031] The second mounting base 7 is connected to the right side of the bottom of the carriage 1. One end of the push rod 5 is rotatably connected to the locking hook 6 via a rotating shaft. One end of the locking hook 6 is rotatably connected to the second mounting base 7 via a rotating shaft. A fixed base 3 is connected to the bottom of the carriage 1 and between the first mounting base 3 and the second mounting base 7. A chain 9 is connected between the support arm 4 and the fixed base 3.

[0032] The second mounting base 7 and the first mounting base 3 are made of high-strength steel and are firmly fixed to the carriage 1 by welding or bolting. The support arm 4 can rotate flexibly within a certain angle range. The support arm 4 is made of alloy steel to ensure that it will not deform or break when subjected to large external forces. One side of the support arm 4 is connected to the push rod 5 through a rotating shaft. This connection method allows the push rod 5 to move with the rotation of the support arm 4. One end of the support arm 4 is connected to a handle 8. The handle 8 is designed to facilitate the operator to apply force. The surface of the handle 8 is covered with rubber or has a textured surface to prevent the operator from slipping during operation. The handle 8 is fixed to the support arm 4 by welding or bolting.

[0033] A bolt is provided between the first mounting base 2 and the support arm 4, which can fix the support arm 4 and the push rod 5 after the lock hook 6 is connected to the rear door panel 2.

[0034] The locking hook 6 is made of hardened steel to ensure its hardness and wear resistance. The push rod 5 plays the role of transmitting force during the entire locking process. Its length and shape are designed according to the actual force transmission path and operating space.

[0035] The main function of chain 9 is to limit the support arm 4 and push rod 5 to prevent them from rotating or moving excessively during operation. Chain 9 is generally made of metal chain, which has high strength and wear resistance. The length of chain 9 is determined according to the range of motion of support arm 4 and push rod 5. At the same time, the connection between chain 9 and support arm 4 and fixed seat 3 must be firm and reliable, which is generally achieved through the cooperation of chain links and connectors.

[0036] The chain 9 is used to limit the position of the support arm 4 and the push rod 5.

[0037] The surface of the rear door panel 2 is provided with a lock groove that is compatible with the lock hook 6.

[0038] The push rod 5 is used to push the support arm 4 and the push rod 5.

[0040] This utility model provides a rear door panel locking mechanism, which uses a push rod 5 with a support arm 4 and a locking hook 6 and a chain 9 at the bottom of the carriage 1, with a first mounting seat 3, a second mounting seat 7 and a fixed seat 3 respectively. It can ensure that the rear door panel is firmly closed even when the vehicle is in motion and is subjected to strong vibrations and bumps. Its structural design is simple and reasonable, and the operator can easily and quickly realize the closing and locking operation of the rear door panel.

[0041] Second Embodiment

[0045] The surface of the circular limiting block 102 is provided with a plurality of limiting through holes 104 that are adapted to the limiting bolt 103.

[0046] The multiple limiting through holes 104 can be opened so that the push rod 5 can be pushed to different angles and connected to the first mounting base 2 by the limiting bolt 103. The limiting bolt 103 is threadedly connected to the circular limiting block 102 and the first mounting base 2.

[0047] A limiting hole adapted to the limiting bolt 103 is provided on the surface of the first mounting base 2. One end of the circular block 101 passes through the first mounting base 2 and is connected to one side of the push rod 5, and can rotate with the push rod 5.

The connection between the circular block 101 and the first mounting base 2 is connected by a bearing.

[0048] The working principle of the rear door panel locking mechanism provided by this utility model is as follows:

[0049] In use, when the support arm 4 and the push rod 5 move the lock hook 6, the circular block 101 drives the circular limit block 102 to rotate. After the support arm 4 and the push rod 5 drive the lock hook 6 to contact and fix with the rear door panel 2, the limit bolt 103 passes through the limit through hole 104 on the surface of the circular limit block 102 and connects with the limit hole on the first mounting base 2.
