They usually have special designs and functions to complete arduous tasks such as building houses, repairing roads, building bridges, mining, and disaster relief. They represent the perfect combination of mechanical power and human wisdom and are indispensable tools for promoting social development and modernization.

[0003] During operation, the locking status of the cab door of existing engineering vehicles directly affects driving safety and ease of operation. During operation, the cab door must be fully locked to prevent the door from shaking due to bumps. During maintenance and repair, the door should be fixed in a half-open position to facilitate personnel entry and exit and tool transfer. When temporarily parked, the door should be lightly locked to prevent the wind from causing the door to open or close.

[0004] Therefore, a multi-position locking mechanism for the cab of an engineering vehicle is proposed to address the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] The following describes an embodiment of this utility model based on its overall structure.

[0033] like Figures 1 to 5 As shown, this utility model provides a multi-position locking mechanism for the cab of an engineering vehicle, including a door 1, a support column 5 on the left side of the door 1, the door 1 and the support column 5 being rotatably connected to form the core motion basis for opening and closing, and a locking component 2 being fixedly provided on the top of the support column 5.

[0034] The locking assembly 2 includes a housing 201. A fixing post 202 is fixedly installed inside the housing 201. A locking limiting groove 203 is opened on the top of the housing 201. A locking hole 204 is opened through the top of the locking limiting groove 203 through the housing 201 to ensure that the locking block 213 can be fully inserted and locked. A door limiting groove 205 is opened on the front side of the housing 201 to limit the opening and closing angle of the door 1 and prevent the door 1 from rotating excessively. A mounting seat 206 is rotatably installed on the outside of the fixing post 202. Sliding grooves 208 are opened on both the left and right sides of the mounting seat 206. A locking seat 209 is slidably installed inside the mounting seat 206. A slider 210 is fixedly installed on both the left and right sides of the locking seat 209 to ensure that the locking seat 209 does not deviate when sliding up and down in the mounting seat 206.

[0035] In this embodiment, the bottom of the mounting base 206 is provided with a circular hole 207, the bottom of the locking base 209 is fixedly provided with a cylinder 211, and a telescopic spring 212 is fixedly sleeved on the outside of the cylinder 211. In its natural state, the telescopic spring 212 pushes up the locking base 209. When the locking base 209 is pressed, the telescopic spring 212 is compressed. After being released, the telescopic spring 212 returns to its original position and pushes the locking base 209 upward. A locking block 213 is fixedly provided on the top of the locking base 209, and a pressing rod 8 that penetrates the outer shell 201 is fixedly provided on the top of the locking base 209.

[0036] There are three cylinders 211. The cylinders 211 are slidably connected to the circular holes 207. The three cylinders 211 are evenly distributed at the bottom of the locking seat 209, corresponding to the three circular holes 211 at the bottom of the mounting seat 206, forming a three-point sliding support.

[0037] A connecting rod 101 is fixedly provided on the right side of the mounting base 206. The connecting rod 101 is fixedly connected to the door 1 and slidably connected to the door limiting groove 205. The linkage between the door 1 and the mounting base 206 is directly realized through the connecting rod 101.

[0038] There are three locking holes 204, corresponding to three positions. When the door 1 is rotated to different angles, the locking block 213 can be engaged in different locking holes 204 to achieve multi-position locking. A distance sensor 7 is fixedly provided on the left side of the locking hole 204 to detect whether the locking block 213 is engaged in the current locking hole 204, thereby detecting the current opening and closing angle of the door 1.

[0039] A three-color warning light 6 is fixedly installed on the right side of the door 1. The three-color warning light 6 is electrically connected to the distance sensor 7. By receiving the signal from the distance sensor 7, it uses different colored lights to reflect the locking status of the door 1.

[0040] A handle 3 is fixedly provided on the front side of the door 1 for people to push and pull the door 1 to facilitate opening and closing the door 1. A window 4 is fixedly provided inside the door 1 to ensure that the driver can observe the outside environment.

[0041] The distance sensor is existing technology and will not be described in detail here; in addition, this utility model also includes a three-color warning light, which is not the main technical point of this patent and will not be described in detail here.

[0042] The working principle and process of a multi-position locking mechanism for the cab of an engineering vehicle:

[0043] When the door 1 is closed, the locking seat 209 is held in place by the elastic force of the telescopic spring 212, and the top locking block 213 is engaged in the corresponding locking hole 204 of the outer casing 201. The distance sensor 7 detects the position of the locking block 213 and sends a signal to the tri-color warning light 6. The warning light turns green, indicating that the locking is safe. At this time, the door 1 cannot be turned at will.

[0044] When the driver needs to adjust the angle of the door 1, pressing the pressing rod 8 that passes through the outer shell 201 causes the locking seat 209 to move down. The sliders 210 on both sides of the locking seat 209 slide along the sliding groove 208 of the mounting base 206, and the telescopic spring 212 is compressed. When the locking block 213 completely disengages from the current locking hole 204 and falls into the locking limit groove 203, the unlocking is completed, and the door 1 can rotate freely. The driver pushes and pulls the door 1 to rotate by pressing the pressing rod 8. When the pressing rod 8 is released, the telescopic spring 212 returns to its elasticity, pushing the locking seat 209 up. The locking block 213 slides along the locking limit groove 203 and accurately engages in the locking hole 204 of the target gear. The distance sensor 7 detects the position of the locking block 213 in real time and uses different colored lights to indicate the locking status of the door 1. When temporarily parking, it engages in the second locking hole 204. When working in a spacious area, it engages in the third locking hole 204.
