Detailed Implementation

[0022] 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.

[0023] Please see Figure 1 - Figure 6 The present invention provides the following technical solution:

[0024] A novel front bumper tilting mechanism includes a frame 1, a four-bar linkage assembly 2, and an inspection door 4. The four-bar linkage assembly 2 is installed inside the frame 1. The four-bar linkage assembly 2 is connected to the inspection door 4 via a spring-loaded latch 3. Auxiliary grooves 5 are provided at both the left and right ends inside the inspection door 4. Limiting structures 6 are connected at both the left and right ends inside the inspection door 4.

[0025] like Figure 1 , Figure 4 and Figure 5 As shown, the spring-loaded latch 3 includes a first connecting plate 301, a first arc plate 302, a second arc plate 303, a first spring 304, a second connecting plate 305, and a locking ball 306. The first connecting plate 301 and the second connecting plate 305 are fixedly connected to the four-bar assembly 2 and the access door 4, respectively, and are located on the left and right sides of the top and bottom of the four-bar assembly 2 and the access door 4, respectively. The first arc plate 302 and the second arc plate 303 are rotatably connected to the inner side of the first connecting plate 301. The first arc plate 302 and the second arc plate 303 form a slot. The locking ball 306 is fixedly connected to the inner side of the second connecting plate 305.

[0026] like Figure 2 and Figure 3 As shown, auxiliary grooves 5 are provided on the left and right sides of the outer side of the inspection door 4. This design is a hidden handle, which can avoid the obstruction caused by the protruding handle. When the finger is inserted into the auxiliary groove 5, each locking ball 306 is aligned with the corresponding locking groove and pushed towards the locking groove, thereby pushing the locking ball 306 into the locking groove.

[0027] Since both the first arc plate 302 and the second arc plate 303 are connected to the first connecting plate 301 via the first spring 304, during the insertion of the ball 306, the first spring 304 is first pressed towards the first connecting plate 301, so the slot formed by the first arc plate 302 and the second arc plate 303 opens, and the ball 306 is directly inserted. After the ball 306 is fully inserted, the force on the first spring 304 decreases, and the first arc plate 302 and the second arc plate 303 exert a force on the ball 306, so that the ball 306 will not come off when it is not subjected to external force.

[0028] When disassembling the access door 4, insert your fingers into the auxiliary groove 5 and pull the access door 4 in the opposite direction of the frame 1. This will cause the locking ball 306 to leave the groove formed by the first arc plate 302 and the second arc plate 303. When the locking ball 306 is pulled, it will exert a large force on the first arc plate 302 and the second arc plate 303, causing the first spring 304 to be pressed again. This will open the first arc plate 302 and the second arc plate 303, allowing the locking ball 306 to be pulled out and the access door 4 to be disassembled.

[0029] like Figure 2 and Figure 6 As shown, the limiting structure 6 includes a connecting rod 601, a cavity 602, a limiting rod 603, and a second spring 604. After the inspection door 4 is connected to the four-bar assembly 2 via the spring latch 3, the connecting rod 601 is rotatably connected inside the inspection door 4. A cavity 602 is provided at the end of the connecting rod 601 away from the inspection door 4. The limiting rod 603 is slidably connected inside the cavity 602. When the limiting rod 603 is pulled outward, the tail end of the limiting rod 603 is fully inserted into the cavity 602. At the same time, the connecting rod 601 is rotated. An opening is provided in the front side plate of the frame 1. After the cavity 602 is rotated to align with the opening, the limiting rod 603 is released. A second spring 604 is provided on the outside of the limiting rod 603. The second spring 604 is located inside the cavity 602. Through the elastic force of the second spring 604, the tail end of the limiting rod 603 enters the opening in the front side plate of the frame 1, thereby providing secondary limiting for the inspection door 4 and improving the firmness of the connection of the inspection door 4.

[0030] Hold the limiting rod 603 and pull it outward so that the tail end of the limiting rod 603 leaves the opening in the front panel of the frame 1. Rotate the connecting rod 601 downward so that the cavity 602 is misaligned with the opening, and then the inspection door 4 can be disassembled.

[0031] The four-bar assembly 2 and the access door 4 are fixed by spring-loaded lock 3, and the frame 1 and access door 4 are fixed by limiting structure 6. The access door 4 is double-connected by double-layer structure to improve its strength.

[0032] Disassembly method: First, disassemble the limiting structure 6, hold the limiting rod 603, let its tail end leave the opening, and rotate the connecting rod 601 so that the cavity 602 is misaligned with the opening. Do the same for both limiting rods 603. Then, insert your fingers into the auxiliary groove 5 and pull the inspection door 4 in the opposite direction of the frame 1 to disassemble it.

[0033] Installation method: Insert your finger into the auxiliary groove 5, align each locking ball 306 with the corresponding locking groove formed by the first arc plate 302 and the second arc plate 303, and push it towards the frame 1 to push the locking ball 306 into the locking groove. Install the access door 4. Then, hold the limiting rod 603 and insert its entire tail end into the cavity 602. At the same time, rotate the cavity 602 to align it with the opening. Release the limiting rod 603, and its tail end will enter the opening for secondary limiting.

[0034] The above completes a series of operations for the novel front guard tilting mechanism. Any content not described in detail in this specification is prior art known to those skilled in the art.
