Description

Technical Field

[0001] The utility model relates to an interior observation mirror for a car. Background Art

[0002] At present, my country stipulates that children under the age of 12 and under 140cm in height cannot sit alone in the front passenger seat of a car. They must sit in the back seat. When there is no one accompanying them in the back seat, the driver needs to observe the situation of the children in the back seat. For commercial vehicles, from a safety perspective, it is also necessary to keep track of the situation of the passengers in the back seat at all times. However, currently, cars are generally only equipped with an interior rearview mirror for observing the situation outside the rear of the car, which cannot effectively observe the situation in the back seat of the vehicle. The driver cannot use the existing interior rearview mirror to fully understand the activities of the people in the back seat at the same time. Summary of the invention

[0023] Unless otherwise specified, the directions of up, down, left, right, front, back, inside and outside in this application document are all based on the directions shown in this embodiment. Figure 1 The directions of the product shown in the figure shall prevail, including up, down, left, right, front, back, inside and outside.

[0024] As shown in the figure, this embodiment includes a housing 2 , a frame 1 mounted on the housing 2 , and a mirror holder 13 with a reflective lens 11 .

[0025] The upper end of the housing 2 of this embodiment is open, and an external connection structure is provided on the housing 2. The external connection structure includes a group of limit blocks 3 respectively provided on the outer sides of the front and rear surfaces of the housing 2, and these limit blocks 3 are used to determine the position of this embodiment during installation.

[0026] The external connection structure also includes two T-shaped grooves 18 with open outer ends on both sides of the lower bottom surface of the housing 2, and each has a claw 4 installed therein. Each claw 4 includes a pointed structure at its lower part, which plays a guiding role during installation. The size of the upper end of the pointed structure is larger, and the root size of the pointed structure is smaller than the size of the larger part, thereby forming an annular groove, which can be matched with the inner hole of the external mechanism of this embodiment for fixing after installation. The upper part of the claw 4 is T-shaped, which cooperates with the T-shaped groove of the lower bottom of the housing 2, and the position of the claw 4 can be adjusted along the T-shaped groove during installation.

[0027] In this embodiment, an embedding groove is provided on the inner side of the left side of the housing 2, and a mounting seat is provided in the embedding groove. The mounting seat includes an outer cover 28 near the left side of the housing 2, and mounting holes 32 are provided at the front and rear parts of the outer cover 28 respectively. Bolts pass through the mounting holes 32 to fix the outer cover 28 on the inner surface of the housing 2. A groove with a protruding ring is provided on the inner surface of the outer cover 28, and the bottom surface of the T-shaped shaft is provided therein, and its shaft portion passes through the shaft hole on the inner cover 26 in the direction of the inner cavity of the housing 2 and is connected to the rubber friction wheel 19. The inner cover 26 has a connecting portion with the outer cover 28, and a concave ring is provided on the connecting portion. The connecting portion of the inner cover 26 is buckled on the outer cover 28, and its concave ring cooperates with the protruding ring of the outer cover 28. The diameter of the rubber friction wheel 19 is preferably larger than the diameter of the inner cover 26.

[0028] The right side plate of the housing 2 is provided with an oblique spring hole 20 and a mounting groove 21 inclined in another direction. The mounting groove 21 is a sunken groove with two through holes on its bottom. The mounting groove 21 is provided with a protrusion near its rear end with a threaded hole. The bolt 8 passes through the spring leaf 7 and is screwed into the threaded hole so that the spring leaf 7 is installed in the mounting groove 21. The size of the spring leaf 7 is adapted to the mounting groove 21.

[0029] A hook spring 6 is arranged in the installation groove. The hook spring 6 is U-shaped, and the middle part thereof is arranged between the installation groove 21 and the spring leaf 7. The front end thereof, i.e., the end away from the protrusion, passes through the through hole at the front of the installation groove 21 and enters the inner cavity of the housing 2. The rear end of the hook spring 6 is inserted into the through hole near the protrusion. Due to the existence of the protrusion, a certain adjustment space is reserved for the hook spring 6 between the bottom surface of the installation groove 21 and the spring leaf 7.

[0030] In this embodiment, a group of upwardly opening card slots 29 are respectively provided on the front and rear inner surfaces of the housing 2, and a protruding card block can be provided in the card slots 29. A frame 1 is provided at the upper end of the housing 2, and card plates 30 corresponding to the card slots 29 are provided below the front and rear surfaces thereof, and each card plate 30 has a card hole. Each card plate 30 is inserted into the corresponding card slot 29, and the card hole on it cooperates with the card block. The frame 1 forms an annular upper surface at the upper end of the housing 2, and particularly leaves space on the left and right sides of the housing 2 below the frame 1.

[0031] In this embodiment, the left and right side plates of the housing 2 are respectively provided with a left shaft hole 17 and a right shaft hole 22 at corresponding positions.

[0032] The frame 13 includes an upper cover plate and two side plates below the upper cover plate, and a frame 12 is arranged between the two side plates, on which a curved reflective lens 11 protruding forward is mounted. The size of the upper cover plate of the frame 13 is adapted to the opening position in the middle of the frame 1, and the upper cover plate can cover the opening part of the frame 1.

[0033] A left rotation shaft 14 and a right rotation shaft 31 are respectively provided on the left side of the left side plate and the right side of the right side plate of the mirror frame 13, and they are respectively installed in the left shaft hole 17 and the right shaft hole 22 on the housing 2.

[0034] An arc plate 15 fixedly connected to the left rotating shaft 14 is arranged above the left rotating shaft 14, and the arc plate 15 is coaxial with the left rotating shaft 14. The arc plate 15 is matched with the circumference of the rubber friction wheel 19.

[0035] An M-shaped guide structure is provided on the right side of the right side plate of the frame 13. The M-shaped guide structure can be a guide rib or a guide groove. The portion of the hook spring 6 extending into the housing 2, that is, the side away from the protrusion, cooperates with the M-shaped guide structure.

[0036] When the M-shaped guide structure is a guide protruding rib, the hook spring 6 can cooperate with its outer peripheral surface; when the hook spring 6 cooperates with the inner surface of the guide protruding rib, a protruding block with a concave upper surface can be provided below the concave portion thereof.

[0037] In this embodiment, arc-shaped first and second baffles 23 and 25 are respectively arranged at the front and rear of the right rotating shaft 31, and a distance is left between them and the right rotating shaft 31. The spring 24 is sleeved on the right rotating shaft 31, one end of which cooperates with the first baffle 23 or the second baffle 25, and the other end passes through the spring hole 20 on the shell 2.

[0038] When the utility model is in use, it can be fixed on the roof of a car or other parts through its external connection structure. The housing 2 is opened downward, and the mirror frame 13 is opened, so that the reflective lens 11 can be pulled out, which is convenient for the driver to observe the situation in the rear row of the vehicle. The cooperation between the M-shaped guide structure and the hook spring 6 is conducive to the positioning of the reflective lens 11. After use, the mirror frame 13 is pushed to make the hook spring 6 separate from the concave part of the M-shaped guide structure, and the mirror frame 13 returns to its original position under the action of the spring 24.
