[0003] There is currently an upper and lower connecting rod type cargo compartment door lock mechanism, which includes a handle, a lock core, a connecting rod, etc. The lock core is rotated by rotating the handle, and the connecting rod is driven up and down by the rotation of the lock core, thereby realizing the locking and unlocking functions.

[0004] However, when transporting the cargo box on bumpy roads, the connecting rod may move unexpectedly due to factors such as bumps and shaking, causing the door lock mechanism to be accidentally unlocked. Utility Model Content

[0005] The main purpose of the utility model is to provide a door lock mechanism, a cargo compartment and a vehicle, aiming to reduce the possibility of accidental unlocking of the door lock mechanism due to bumps.

[0006] To achieve the above-mentioned purpose, the door lock mechanism proposed by the present invention comprises:

[0007] include:

[0008] Lock cylinder, movably arranged on the door body;

[0009] A lock rod, the lock core drivingly connected to the lock rod, so that the lock rod moves to a locking position to close the door body or moves to an unlocking position to open the door body; and

[0010] An anti-lifting assembly is arranged on the door body and connected to the locking rod to increase the damping of the locking rod moving toward the unlocking position.

[0011] In one embodiment, the anti-opening assembly includes an elastic member, which is disposed on the door body and elastically connected to the locking rod to increase the damping of the locking rod moving toward the unlocking position.

[0012] In one embodiment, the elastic member is a spring sheet, both ends of which are fixed to the door body, and the middle portion of the spring sheet protrudes away from the door body to form an elastic portion, and the elastic portion elastically abuts against the outer peripheral surface of the locking rod to increase the damping of the locking rod moving toward the unlocking position.

[0013] In one embodiment, the lock core is rotatably disposed on the door body, one end of the lock rod is rotatably connected to the lock core and is away from the rotation center of the lock core, and the lock rod is switched between the locking position and the unlocking position by the rotation of the lock core;

[0014] Wherein, the elastic portion is arranged between the locking position and the unlocking position of the locking rod.

[0015] In one embodiment, the spring sheet is close to one end of the lock rod connected to the lock core.

[0016] In one embodiment, the locking rod and the anti-lifting assembly are both arranged on the inner side of the door body.

[0017] In one embodiment, the door lock mechanism further includes a guide member, the guide member is fixed to the door body, and one end of the lock rod away from the lock core is movably inserted into the guide member.

[0018] In one embodiment, the guide member is provided with an oblong hole penetrating the guide member along the extension direction of the locking rod, the length direction of the oblong hole is arranged along the movable direction of the locking rod, and the locking rod is movably inserted into the oblong hole.

[0025] The door lock mechanism in the technical solution of the utility model includes a lock core, a lock rod and an anti-bumping assembly. The lock core drives the lock rod, and the lock core moves to drive the lock rod to switch between the locking position and the unlocking position. When the lock rod is in the locking position, the door lock mechanism locks the door body to ensure that the door body is closed; when the lock rod is in the unlocking position, the door lock mechanism unlocks the door body and the door body can be opened. The anti-bumping assembly is arranged on the door body and connected to the lock rod, which increases the damping of the lock rod moving toward the unlocking position, so that the lock rod needs to overcome a certain resistance when moving toward the unlocking position, and the force generated by the bumping and shaking is small, and it is difficult to drive the lock rod to move toward the unlocking position, thereby reducing the possibility of the door lock mechanism being accidentally unlocked due to bumping and shaking. On the other hand, the anti-bumping assembly is arranged on the door body and connected to the lock rod, which increases the connection and support between the lock rod and the door body, can improve the stability of the lock rod, and reduce the shaking degree of the lock rod under bumping and shaking conditions, thereby reducing the possibility of the lock rod moving toward the unlocking position, thereby reducing the possibility of the door lock mechanism being accidentally unlocked. On the other hand, increasing the damping of the lock rod's movement toward the unlocked position reduces the possibility of accidental unlocking of the door lock mechanism. Compared with adding a locking component to restrict the lock rod from moving toward the unlocked position, this method does not add any extra unlocking steps for the user. When unlocking the door, the user still only needs to operate the lock cylinder and only needs to slightly increase the force applied to the lock cylinder. This method has fewer steps and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] In one embodiment of the present invention, the door lock mechanism 100 comprises:

[0046] A lock core 110 is movably disposed on the door body 210;

[0047] The lock rod 120 is driven by the lock core 110 to connect to the lock rod 120, so that the lock rod 120 moves to a locking position to close the door body 210 or moves to an unlocking position to open the door body 210; and

[0048] The anti-lifting assembly 130 is disposed on the door body 210 and connected to the locking rod 120 to increase the damping of the locking rod 120 moving toward the unlocking position.

[0049] The door lock mechanism 100 in the technical solution of the utility model includes a lock core 110, a lock rod 120 and an anti-bumping assembly 130. The lock core 110 drives and connects the lock rod 120. The lock core 110 moves to drive the lock rod 120, so that the lock rod 120 switches between the locked position and the unlocked position. When the lock rod 120 is in the locked position, the door lock mechanism 100 locks the door body 210 to ensure that the door body 210 is closed; when the lock rod 120 is in the unlocked position, the door lock mechanism 100 unlocks the door body 210, so that the door body 210 can be opened. The anti-bumping assembly 130 is arranged on the door body 210 and connected to the lock rod 120, which increases the damping of the lock rod 120 moving toward the unlocked position, so that the lock rod 120 needs to overcome a certain resistance when moving toward the unlocked position, and the force generated by the bumping and shaking is small, and it is difficult to drive the lock rod 120 to move toward the unlocked position, thereby reducing the possibility of the door lock mechanism 100 being accidentally unlocked due to bumping and shaking. On the other hand, the anti-bumping assembly 130 is disposed on the door body 210 and connected to the lock rod 120, which increases the connection and support between the lock rod 120 and the door body 210, can improve the stability of the lock rod 120, and reduce the shaking degree of the lock rod 120 in the case of bumps and shakes, thereby reducing the possibility of the lock rod 120 moving toward the unlocked position, thereby reducing the possibility of accidental unlocking of the door lock mechanism 100. On the other hand, the method of reducing the accidental unlocking of the door lock mechanism 100 by increasing the damping of the lock rod 120 moving toward the unlocked position does not increase the user's unlocking steps compared to the method of adding another locking assembly to restrict the lock rod 120 from moving toward the unlocked position. When unlocking, the user still only needs to operate the lock cylinder 110 to move, and only needs to slightly increase the force applied to the lock cylinder 110, which has fewer steps and is easy to operate.

[0050] The anti-bumping assembly 130 can increase the damping of the lock rod 120 moving toward the unlocking position through various forms such as a damper and a spring.

[0051] In one embodiment, the anti-lifting assembly 130 includes an elastic member, which is disposed on the door body 210 and elastically connected to the locking rod 120 to increase the damping of the locking rod 120 moving toward the unlocking position.

[0052] In an embodiment of the utility model, the anti-opening assembly 130 includes an elastic member, which is arranged on the door body 210 and elastically connected to the locking rod 120. The elastic deformation ability of the elastic member increases the damping of the locking rod 120 moving toward the unlocking position. The elastic member can be in various forms such as a spring, an elastic cable, a spring sheet, an elastic block, etc., with a simple structure, easy implementation and low cost.

[0053] In one embodiment, the elastic member is a spring sheet 131, both ends of which are fixed to the door body 210, and the middle portion of the spring sheet 131 protrudes in a direction away from the door body 210 to form an elastic portion 1311, and the elastic portion 1311 elastically abuts against the outer peripheral surface of the locking rod 120 to increase the damping of the locking rod 120 moving toward the unlocking position.

[0054] Combination Figure 2 , Figure 4 , Figure 5 as well as Figure 7 In the embodiment of the utility model, the elastic member is a spring sheet 131, the two ends of the spring sheet 131 are fixed on the door body 210, the middle part is arched to form an elastic part 1311, and the elastic part 1311 elastically abuts against the outer peripheral surface of the lock rod 120, thereby increasing the damping of the lock rod 120 moving toward the unlocking position. The spring sheet 131 has a simple structure, is easy to manufacture and install, and is easy to replace, thereby reducing the production cost and maintenance cost. On the other hand, the spring sheet 131 elastically abuts against the lock rod 120, and there is friction between the lock rod 120 and the spring sheet 131. If the lock rod 120 moves toward the unlocking position, as the elastic part 1311 deforms, the elastic force applied to the lock rod 120 by the elastic part 1311 will increase, and the friction between the lock rod 120 and the spring sheet 131 will also increase, that is, the resistance of the lock rod 120 moving toward the unlocking position is increased, further reducing the possibility of the door lock mechanism 100 being unlocked due to accidental bumps. The specific protruding height and shape of the elastic portion 1311 can be adjusted and designed as needed to adapt to locking rods 120 of different weights and sizes, which are not limited here.

[0055] Reference Figure 1 and Figure 3 Specifically in this embodiment, a locking rod 120 is provided on opposite sides of the lock core 110 , and the lock core 110 drives the two locking rods 120 to move simultaneously. A spring sheet 131 can be provided corresponding to one of the locking rods 120 , or a spring sheet 131 can be provided corresponding to both of the locking rods 120 .

[0056] In one embodiment, the lock core 110 is rotatably disposed on the door body 210, and one end of the lock rod 120 is rotatably connected to the lock core 110 and is away from the rotation center of the lock core 110, so that the lock rod 120 is switched between the locking position and the unlocking position by the rotation of the lock core 110;

[0057] The elastic portion 1311 is disposed between the locking position and the unlocking position of the locking rod 120 .

[0058] Reference Figures 5 to 7In the embodiment of the utility model, one end of the lock rod 120 is connected to the lock core 110 for rotation. The rotation of the lock core 110 drives the end of the lock rod 120 to move around the rotation center of the lock core 110, thereby driving the entire lock rod 120 to move. The lock rod 120 is switched to the locking position or the unlocking position by the forward and reverse rotation of the lock core 110. The structure is simple and the operation is convenient. The elastic part 1311 is arranged between the locking position and the unlocking position of the lock rod 120. In the process of the lock rod 120 moving toward the unlocking position, it is ensured that the elastic part 1311 can provide damping for the lock rod 120. Specifically in this embodiment, when the lock rod 120 is in the locking position, the extension direction of the elastic member is perpendicular to the extension direction of the lock rod 120. The lock rod 120 compresses the elastic part 1311 to deform. The elastic part 1311 generates a certain elastic force on the lock rod 120, so that the lock rod 120 is more stably maintained in the locking position, ensuring the locking function of the door lock mechanism 120.

[0059] In one embodiment, the spring piece 131 is close to one end of the lock rod 120 connected to the lock cylinder 110 .

[0060] Combination Figure 1 and Figure 3 In the embodiment of the utility model, the rotation of the lock core 110 drives the lock rod 120 to move, so that the displacement distance of the end of the lock rod 120 connected to the lock core 110 is greater than the displacement distance of the end of the lock rod 120 away from the lock core 110, and the spring sheet 131 is arranged close to the end of the lock rod 120 connected to the lock core 110, so that the spring sheet 131 is mainly used to reduce the possibility of the end of the lock rod 120 connected to the lock core 110 moving toward the unlocking position, which makes it easier to reduce the possibility of the lock core 110 moving, thereby making it easier to reduce the possibility of accidental unlocking of the door lock mechanism 100, thereby ensuring the anti-bumping effect of the spring sheet 131.

[0061] In one embodiment, the locking rod 120 and the anti-lifting assembly 130 are both disposed on the inner side of the door body 210 .

[0062] In the embodiment of the present utility model, the lock rod 120 and the anti-bumping assembly 130 are both arranged on the inner side of the door body 210, that is, arranged on the side of the door body 210 away from the external environment. For example, if the door lock mechanism 100 is applied to the cargo compartment of a vehicle, the lock rod 120 and the anti-bumping assembly 130 are both arranged inside the cargo compartment, which reduces the possibility of the lock rod 120 and the anti-bumping assembly 130 being damaged by others, and also reduces the impact of rain, snow, dust, etc. on the lock rod 120 and the anti-bumping assembly 130, thereby ensuring the safety of the door lock mechanism 100 and extending the service life of the door lock mechanism 100. The door lock mechanism 100 also includes a handle, which is arranged on the outer side of the door body 210, that is, the side of the door body 210 facing the external environment. The handle is connected to the lock core 110, and the lock core 110 on the inner side of the door body 210 is rotated by turning the handle, thereby locking or unlocking the door lock mechanism 100.

[0063] In one embodiment, the door lock mechanism 100 further includes a guide member 140 , which is fixed to the door body 210 , and one end of the lock rod 120 away from the lock core 110 is movably disposed in the guide member 140 .

[0064] Reference Figure 6 In the embodiment of the present utility model, the door lock mechanism 100 further includes a guide member 140, which ensures the movement trajectory of the lock rod 120 during the movement process, improves the accuracy and stability of the movement of the lock rod 120, and thus ensures the stability and reliability of the door lock mechanism 100 when locking and unlocking. Specifically in this embodiment, the lock core 110 rotates to drive one end of the lock rod 120 to move, so that the other end of the lock rod 120 extends out of the door body 210 to achieve locking, or the other end of the lock rod 120 retracts into the door body 210 to achieve unlocking. The guide member 140 is arranged at the end of the lock rod 120 away from the lock core 110, which improves the accuracy and stability of the end of the lock rod 120 away from the lock core 110 when moving, and further improves the stability and reliability of the door lock mechanism 100 when locking and unlocking. On the other hand, the guide member 140 and the lock core 110 are arranged at both ends of the lock rod 120, which improves the stability of the lock rod 120 and reduces the possibility of shaking of the lock rod 120.

[0065] In one embodiment, the guide member 140 is provided with an oblong hole 141 penetrating the guide member 140 along the extension direction of the locking rod 120 . The length direction of the oblong hole 141 is arranged along the movable direction of the locking rod 120 , and the locking rod 120 is movably inserted into the oblong hole 141 .

[0066] Reference Figure 8 In an embodiment of the utility model, the guide member 140 is provided with an oblong hole 141, and the locking rod 120 passes through the guide member 140 through the oblong hole 141. The length direction of the oblong hole 141 is arranged along the movable direction of the locking rod 120, which not only ensures the guiding function of the guide member 140 on the locking rod 120, but also avoids excessive restriction of the locking rod 120 so that the locking rod 120 cannot move. On the other hand, the oblong hole 141 is easy to process and has a low manufacturing cost.

[0067] The utility model also provides a cargo compartment, comprising:

[0068] The door lock mechanism 100 described above;

[0069] Carriage 220; and

[0070] The door body 210 is movably disposed on the compartment body 220 to open or close the compartment body 220;

[0071] The door lock mechanism 100 is disposed on the door body 210 , and the door body 210 is locked or unlocked with the compartment body 220 through the door lock mechanism 100 .

[0072] The specific structure of the door lock mechanism 100 refers to the above embodiment. Since the cargo compartment adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the cargo compartment can be a container or a cargo compartment of a van, etc. By adopting the above door lock mechanism 100, the possibility of the door lock mechanism 100 being accidentally unlocked in the case of bumps and shakes in the cargo compartment is reduced, which also reduces the possibility of the door body 210 being accidentally opened in the case of bumps and shakes, thereby ensuring the safety of the cargo compartment during transportation and reducing the possibility of goods falling in the cargo compartment.

[0073] The utility model also provides a vehicle, including the above-mentioned door lock mechanism 100.
