Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electric tricycle cargo box door locks, specifically relating to a hidden lock latch for the cargo box. Background Technology
[0002] Currently, the doors of electric tricycles have an external latch structure. When closing the door, the user needs to hold the door with one hand, push it to the latch fixing position, and then pull down the latch with the other hand to secure the door. In addition, to ensure that the door does not fall off while the vehicle is in motion, there is a locking spring inside the latch that constantly applies an external force to the latch position. Opening and closing the door requires the user to apply external force to the latch to overcome the tension of the spring. In special circumstances, the above actions cannot be completed with one hand.
[0003] Meanwhile, the external door latch is a protrusion on the outside of the vehicle door. During loading, the protruding edge of the vehicle can easily increase the risk of clothing, luggage, or people getting caught or hit, which is especially dangerous when driving or parking in a narrow space. Utility Model Content
[0004] The purpose of this utility model is to provide a hidden lock for the carriage that can be operated with one hand, making it more convenient to use and effectively improving work efficiency.
[0005] To achieve the above objectives, this utility model provides a concealed lock for a vehicle compartment, comprising a lock body embedded in the front door of the vehicle compartment and a lock pin protruding from the side of the side door of the vehicle compartment. The lock body has a slot for accommodating the lock pin, and a lock cylinder is rotatably connected to the slot via a rotating pin. A lock rod is connected above the lock cylinder. The lock body has a sliding groove for the lock rod to pass through, and the front door of the vehicle compartment has a sliding track for the lock rod to pass through, and an opening for the upper end of the lock rod to extend outward. A push-button switch is installed at the opening via a switch fixing base, and the push-button switch is fitted with the end of the lock rod.
[0006] As a further embodiment of this utility model: the end of the lock cylinder away from the lock body is a semi-circular structure with the opening facing inward.
[0007] As a further embodiment of this utility model: the lock cylinder is connected to a protrusion that matches the slot, and the lock cylinder is connected to the lock rod through the protrusion.
[0008] As a further embodiment of this utility model: the upper end of the locking rod is bent outward to form an acute angle.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0010] 1. The lock body is embedded in the front door of the vehicle, and the lock pin protrudes and is connected to the side of the side door of the vehicle. When the lock pin and the lock body are connected, the entire lock can be hidden, creating a seamless appearance, which enhances the technological and design sense of the vehicle and makes the overall side of the vehicle more integrated.
[0011] 2. The concealed buckle structure design can effectively avoid the risks of traditional buckles snagging on clothes, luggage, etc., which is especially safer when driving or parking in narrow spaces, further improving the convenience and safety of use;
[0012] 3. Since the concealed latch is completely hidden inside the vehicle when not in use, it can avoid the influence of the external environment (rain, snow, dust, etc.), reduce damage caused by corrosion and wear, and extend the service life of the latch.
[0013] 4. The concealed latch has no protruding parts or grooves, making it less prone to accumulating dirt and easy to clean;
[0014] 5. It can be operated with one hand, is simple and convenient to use, and can effectively improve work efficiency. Attached Figure Description
[0015] Figure 1 This is a structural schematic diagram of the concealed lock for the carriage of this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] like Figure 1 and Figure 2 As shown, the concealed lock of the carriage includes a lock body 9 embedded in the front door 1 of the carriage and a lock pin 14 protruding from the side of the side door 15 of the carriage. The lock body 9 is provided with a slot 10 for accommodating the lock pin 14. A lock cylinder 11 is rotatably connected to the slot 10 through a rotating pin 8. A lock rod 3 is connected above the lock cylinder 11. The lock body 9 is provided with a slide groove 7 for the lock rod 3 to pass through. The front door 1 of the carriage is provided with a slide rail (not shown in the figure) for the lock rod 3 to pass through, and an opening 2 for the upper end of the lock rod 3 to extend outward. A push-button switch 6 is installed at the opening 2 through a switch fixing base 4. The push-button switch 6 is slidably connected to the switch fixing base 4 and is in contact with the end of the lock rod 3.
[0020] To facilitate the direct pressing and insertion of the locking pin 14 into the slot 10, the end of the lock cylinder 11 away from the lock body 9 is a semi-circular structure with the opening 2 facing inward. When the side door 15 of the carriage is lifted so that the locking pin 14 contacts the lock cylinder 11, the lock cylinder 11 will be subjected to force and rotate around the rotating pin 8 along the tangent of the semicircle, so that the locking pin 14 can smoothly enter the slot 10.
[0021] To further enhance the overall concealment of the latch, a protrusion 12 matching the slot 10 is connected to the lock cylinder 11, and the lock cylinder 11 is connected to the lock rod 3 via the protrusion 12. The protrusion 12 can naturally mate with the slot 10, creating a seamless appearance.
[0022] When the latch is opened by the push-button switch 6, the upper end of the lock rod 3 is further bent outward to form an acute angle to improve the ease of unlocking. In its natural state, the upper end of the lock rod 3 is attached to the push-button switch 6. By pressing the push-button switch 6, the lock cylinder 11 can be rotated around the rotating pin 8, thereby releasing the restriction on the lock pillar 14 and allowing the side door 15 of the carriage to open outward.
[0023] When this utility model is in use, if the side door 15 of the carriage needs to be closed, one hand only needs to apply external force to lift the side door 15 of the carriage. The hinge 13 of the side door 15 of the carriage will make a circular motion, so that the locking pin 14 contacts the lock cylinder 11. The lock cylinder 11 has a semi-circular structure. When it contacts the locking pin 14, the lock cylinder 11 will rotate along the semi-circular tangent of the rotating pin 8. When the rotation height is greater than the diameter of the locking pin 14, the locking pin 14 will enter the interior of the lock body 9. When the diameter of the locking pin 14 enters the interior of the lock body 9, there is no lateral squeezing force on the lock cylinder 11. The lock cylinder 11 will fall under the action of gravity. At the same time, the protrusions 12 at both ends of the lock cylinder 11 will be stuck on the lock body 9, completing the door closing and locking action.
[0024] When the side door 15 of the carriage is to be opened: an external force is applied to the push button switch 6, and the push button switch 6 causes the lock cylinder 11 to rotate along the rotating pin 8 through the locking rod 3. At the same time, the lock cylinder 11 is lifted up, releasing the self-locking state, and the lock pin 14 slides out along the inside of the lock body 9 to complete the door opening action.
