Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted refrigerators, in particular to a rope-type vehicle-mounted refrigerator adopting a photoelectric sensor. Background Art

[0002] The applicant has applied for a rope-driven car refrigerator with application number 2022221584629. Since this type of refrigerator requires a rope to drive the drawer to open and close, the rope needs to be tightened to drive the drawer to move very smoothly. In the traditional method, the rope is completely tightened, which means that its opening and closing need to be operated by independent switches. However, users still tend to close the drawer by pushing the drawer. In the original technology, it is impossible to drive the pull-out drawer to move by external force. First, the rope reel has a great control force on the rope, and it is basically impossible for the user to overcome the force of the rope reel to push the pull-out drawer. Second, if the external force is too large and causes the drawer to move, it will inevitably cause the rope to move as a whole. When the motor is not working, the rope moves on the rope reel, which will cause damage to the rope reel. Utility Model Content

[0029] Reference Figures 1 to 5 , a rope-type vehicle refrigerator using a photoelectric sensor, comprising:

[0030] A box body 10, wherein a cold storage chamber 11 is disposed in the box body 10, an opening communicating with the cold storage chamber 11 is disposed on the surface of the box body 10, and a winding member is disposed at the front end of the cold storage chamber 11;

[0031] A pull-out drawer 20, wherein the pull-out drawer 20 is movably installed in the cold storage chamber 11 along the opening, and a sunshade 50 is provided on the outer surface of the pull-out drawer 20;

[0032] A rope drum 30, the rope drum 30 is arranged on the box body 10, the rope drum 30 is provided with a rope 40 and a motor for driving the rope 40 to move back and forth, the rope 40 is wound on the winding member, the rope 40 is connected to the pull-out drawer 20 from both sides and tensioned, and a tension spring 41 is provided on the rope 40;

[0033] The photoelectric sensor 60 includes a photoelectric receiver 61 disposed in the cold storage chamber 11 and a photoelectric transmitter 62 facing the photoelectric receiver 61 . The shading plate 50 can move between the photoelectric transmitter 62 and the photoelectric receiver 61 during the movement.

[0034] The rope 40 is tightened by the tensioning spring 41, thereby changing the rope 40 from the original rigid tension to the elastic tension. Under normal circumstances, when the user controls the pull-out drawer 20 to be fully opened, the shading plate 50 moves to between the photoelectric transmitter 62 and the photoelectric receiver 61 to block the photoelectric signal of the photoelectric sensor 60. When the user needs to close the pull-out drawer 20, the pull-out drawer 20 is slightly pushed. Since a tensioning spring 41 is provided on the rope 40 to tighten the rope 40, the rope drum 30 can be short-displaced a certain distance by the deformation margin brought by the tensioning spring 41 when the pull-out drawer 20 is not working. The short displacement of the pull-out drawer 20 will cause the shading plate 50 to withdraw from between the photoelectric transmitter 62 and the photoelectric receiver 61, so that the photoelectric receiver 61 receives the signal sent by the photoelectric transmitter 62 again. At this time, it is judged that the user needs to close the pull-out drawer 20 and the motor is controlled to drive the rope drum 30 to work, thereby driving the pull-out drawer 20 to close. Through this method, the user can control the closing of the drawer 20 by pushing the drawer 20, which is more in line with the user's usage habits.

[0035] In the first embodiment, the bottom of the drawer 20 is preferably provided with a front mounting groove 21 and a rear mounting groove 22, and the two ends of the rope 40 are respectively installed in the front mounting groove 21 and the rear mounting groove 22 along the front-to-back direction, and the two tension springs 41 are provided, and the front ends of the two tension springs 41 are respectively fixed to the ends of the rope 40, and the ends of the two tension springs 41 are respectively abutted against the inner walls of the front mounting groove 21 and the rear mounting groove 22 to tighten the rope 40. In order to facilitate the arrangement of the rope 40, it is preferred that a mounting platform 201 is provided at the bottom of the drawer 20, and the front mounting groove 21 and the rear mounting groove 22 are provided on the mounting platform 201, and the front end of the mounting platform 201 is provided with a front wire receiving groove 211 extending to the front side wall of the front mounting groove 21, and the rear end of the mounting platform 201 is provided with a rear wire receiving groove 221 extending to the rear side wall of the rear mounting groove 22, and the rope 40 is passed through the front wire receiving groove 211 and the rear wire receiving groove 221.

[0036] In this manner, when the drawer 20 is pushed, the ends of the rope 40 are relatively displaced with the drawer 20 in the front mounting groove 21 and the rear mounting groove 22 by the tension spring 41, but from the perspective of the entire vehicle refrigerator, the rope 40 is in a stationary state as a whole. That is, the drawer 20 moves inward, thereby driving the front mounting groove 21 and the rear mounting groove 22 to move inward, and during the process of the front mounting groove 21 and the rear mounting groove 22 moving inward, since the rope 40 is stationary, both ends of the rope 40 move forward in the front mounting groove 21 and the rear mounting groove 22, so that the tension spring 41 in the front mounting groove 21 is further compressed, and the tension spring 41 in the rear mounting groove 22 is relaxed.

[0037] In the present embodiment, the front mounting groove 21 and the rear mounting groove 22 are preferably both lower opening structures, and baffles are provided on both sides of the opening at the front end of the front mounting groove 21 and both sides of the opening at the rear end of the rear mounting groove 22 to prevent the tension spring 41 and the rope 40 from falling off from the front mounting groove 21 and the rear mounting groove 22.

[0038] In the second embodiment, the rope 40 preferably includes a front section and a rear section, and the tension spring 41 is arranged between the front section and the rear section and is used to connect the front section and the rear section. In this way, when the drawer 20 is pushed, the transition effect of the tension spring 41 allows the front section and the rear section to move when the rope drum 30 is not working, so that the drawer 20 can be pushed without damaging the rope drum 30.

[0039] In this solution, the shading plate 50 is preferably disposed on the bottom surface of the pull-out drawer 20 , and the photoelectric sensor 60 is disposed on the bottom surface of the cold storage chamber 11 .

[0040] In this embodiment, the bottom surface of the cold storage chamber 11 is preferably provided with a sunken wire groove 71, and the sunken wire groove 71 is used to fix the wires connected to the photoelectric sensor 60, so that the wires can be well stored and will not be caught by the pull-out drawer 20.

[0041] In the above scheme, it is preferred that when the pull-out drawer 20 is fully opened, the shading plate 50 is located between the photoelectric transmitter 62 and the photoelectric receiver 61. However, in actual practice, the length of the shading plate 50 can be adjusted so that when the drawer is fully opened, the shading plate 50 just does not block the photoelectric transmitter 62 and the photoelectric receiver 61, while in other positions, the shading plate 50 is in a state of blocking between the photoelectric transmitter 62 and the photoelectric receiver 61.

[0042] In this solution, it is preferred that a mounting seat 70 is detachably provided on the bottom surface of the cold storage chamber 11, the photoelectric sensor 60 is provided on the mounting seat 70, and the winding member is provided on the mounting seat 70, so as to facilitate installation.

[0043] Preferably, a fixed slide rail is provided in the storage cold chamber 11 , and a movable slide rail connected to the fixed slide rail is provided on the pull-out drawer 20 . Preferably, the fixed slide rail is provided on the mounting seat 70 .

[0044] In this solution, the winding member is preferably a turntable 42, and the outer circumference of the turntable 42 is provided with an annular winding groove for the rope 40 to be embedded therein, so that the movement of the rope 40 is smoother. In other embodiments, the winding member can also be an independent winding column.

[0045] In the present embodiment, the shading plate 50 preferably includes a front baffle 52 and a rear baffle 51 which are arranged on the rear side of the bottom of the pull-out drawer 20, and a gap is arranged between the front baffle 52 and the rear baffle 51, so that when the pull-out drawer 20 is opened, the signal between the photoelectric receiver 61 and the photoelectric transmitter 62 is first off, then on, and then off, and when the pull-out drawer 20 is closed, the signal between the photoelectric receiver 61 and the photoelectric transmitter 62 is first on, then off, and then on. In this way, by controlling the transmission frequency of the signal, the phenomenon of false touch can be avoided.

[0046] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
