DETAILED DESCRIPTION
[0026] Hereinafter, the present application will be further described in conjunction with specific embodiments, and it should be noted that the following described embodiments or technical features can be combined arbitrarily to form new embodiments, without conflict.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0029] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0030] The following description, in conjunction with the accompanying drawings, further illustrates this application:
[0031] like Figures 1 to 8 As shown, this application provides an angle rotation detection mechanism, including a pin 1, a base 2, a connecting rod 3, and a rotating hook 4. The pin 1 is located on the periphery of the base 2. The connecting rod 3 is slidably disposed on the base 2. The rotating hook 4 includes a rotating end 41 and a locking end 42. The rotating end 41 is rotatably connected to the base 2. The locking end 42 is adapted to rotate along the rotating end 41 (with the rotating end 41 as the rotation center) and engage with the pin 1. The connecting rod 3 is movably connected to the rotating hook 4 between the rotating end 41 and the locking end 42. The connecting rod 3 is adapted to slide with the rotation of the locking end 42. A feedback device 6 is provided on the base 2. When the connecting rod 3 slides relative to the base 2, it is adapted to trigger the feedback device 6 to send a feedback signal. The feedback signal can be directly transmitted or indirectly converted and accepted by the user, thereby facilitating the user to judge the state of the rotating hook 4.
[0032] The detection mechanism amplifies the activity of the detection object, namely the rotating hook 4, by converting the rotational engagement state of the rotating hook 4 into the sliding state of the connecting rod 3. The feedback device 6 detects the sliding state of the connecting rod 3, thereby obtaining the rotational engagement state of the rotating hook 4 more accurately, thus determining the rotation angle of the rotating hook 4 and whether the rotating hook 4 and the pin 1 are correctly engaged, which can effectively reduce the probability of feedback errors.
[0033] In some embodiments, the pin 1 is adapted to be fixed on the structure around the base 2, and the pin 1 will not rotate with the base 2. The pin 1 can be set on the side of the base 2 that needs to be locked. The base 2 can be locked on this side by means of a rotating hook 4, thereby limiting the rotation of the base 2 and fixing the rotation angle.
[0034] like Figure 1 , 3In the embodiments shown in Figs. 6 and 8, the locking end 42 is in the form of a hook, and the opening direction of the locking end 42 is towards the direction of the pin shaft 1. When the locking end 42 rotates towards the direction of the pin shaft 1, the locking end 42 can be correctly hooked on the pin shaft 1, so that no false structural interference occurs between the locking end 42 and the pin shaft 1, thereby realizing structural connection, so as to stabilize and limit the rotating state of the base 2 through the cooperation of the pin shaft 1 and the rotating hook 4.
[0035] In the embodiments shown in Figs. 6 and 8, the locking end 42 is in the form of a hook, and the opening direction of the locking end 42 is towards the direction of the pin shaft 1. When the locking end 42 rotates towards the direction of the pin shaft 1, the locking end 42 can be correctly hooked on the pin shaft 1, so that no false structural interference occurs between the locking end 42 and the pin shaft 1, thereby realizing structural connection, so as to stabilize and limit the rotating state of the base 2 through the cooperation of the pin shaft 1 and the rotating hook 4. Figure 1 2 In the embodiments shown in Figs. 6 and 8, the locking end 42 is in the form of a hook, and the opening direction of the locking end 42 is towards the direction of the pin shaft 1. When the locking end 42 rotates towards the direction of the pin shaft 1, the locking end 42 can be correctly hooked on the pin shaft 1, so that no false structural interference occurs between the locking end 42 and the pin shaft 1, thereby realizing structural connection, so as to stabilize and limit the rotating state of the base 2 through the cooperation of the pin shaft 1 and the rotating hook 4.
[0036] In some embodiments, the reset device 5 is a tension spring, which is simple in structure, convenient to install, and low in cost.
[0037] In the embodiments shown in Figs. 6 and 8, the locking end 42 is in the form of a hook, and the opening direction of the locking end 42 is towards the direction of the pin shaft 1. When the locking end 42 rotates towards the direction of the pin shaft 1, the locking end 42 can be correctly hooked on the pin shaft 1, so that no false structural interference occurs between the locking end 42 and the pin shaft 1, thereby realizing structural connection, so as to stabilize and limit the rotating state of the base 2 through the cooperation of the pin shaft 1 and the rotating hook 4. Figure 1 3 In the embodiments shown in Figs. 6 and 8, the locking end 42 is in the form of a hook, and the opening direction of the locking end 42 is towards the direction of the pin shaft 1. When the locking end 42 rotates towards the direction of the pin shaft 1, the locking end 42 can be correctly hooked on the pin shaft 1, so that no false structural interference occurs between the locking end 42 and the pin shaft 1, thereby realizing structural connection, so as to stabilize and limit the rotating state of the base 2 through the cooperation of the pin shaft 1 and the rotating hook 4.
[0038] In some embodiments, the protruding block 31 is in the form of a connecting pin.
[0039] In the embodiments shown in Figs. 6 and 8, the locking end 42 is in the form of a hook, and the opening direction of the locking end 42 is towards the direction of the pin shaft 1. When the locking end 42 rotates towards the direction of the pin shaft 1, the locking end 42 can be correctly hooked on the pin shaft 1, so that no false structural interference occurs between the locking end 42 and the pin shaft 1, thereby realizing structural connection, so as to stabilize and limit the rotating state of the base 2 through the cooperation of the pin shaft 1 and the rotating hook 4. Figure 1 4 In the embodiments shown in Figs. 6 and 8, the locking end 42 is in the form of a hook, and the opening direction of the locking end 42 is towards the direction of the pin shaft 1. When the locking end 42 rotates towards the direction of the pin shaft 1, the locking end 42 can be correctly hooked on the pin shaft 1, so that no false structural interference occurs between the locking end 42 and the pin shaft 1, thereby realizing structural connection, so as to stabilize and limit the rotating state of the base 2 through the cooperation of the pin shaft 1 and the rotating hook 4.
[0040] In some embodiments, the path direction of the idle stroke section 431 is adapted to the sliding direction of the connecting rod 3, so that the initial sliding action of the connecting rod 3 can be adapted by the idle stroke section 431, and then will not be transmitted to the rotating hook 4, avoiding the unlocking of the rotating hook 4 and the pin shaft 1.
[0041] As shown in the rotating trajectory of the rotating hook 4, Figures 3 to 5 As shown in the rotating trajectory of the rotating hook 4,
[0042] As shown in the rotating trajectory of the rotating hook 4, Figures 1 to 2 As shown in the rotating trajectory of the rotating hook 4,
[0043] In some embodiments, a plurality of rotating hooks 4 can be arranged on one side or both sides of the connecting rod 3 along the sliding direction, so that the locking between the base 2 and the pin shaft 1 along both sides of the connecting rod 3 in the sliding direction can be achieved, that is, the rotating locking of the base 2 in the positive and negative two states of 180° rotation can be achieved.
[0044] As shown in the rotating trajectory of the rotating hook 4, Figure 2 As shown in the rotating trajectory of the rotating hook 4,
[0045] In some embodiments, when the rotating hook 4 and the pin shaft 1 are hooked, the sliding direction of the connecting rod 3 is perpendicular to the axis of the pin shaft 1, the rotating plane of the rotating hook 4 is perpendicular to the axis of the pin shaft 1, and the rotating plane of the rotating hook 4 is parallel to the sliding direction of the connecting rod 3. This arrangement is more stable, the linkage design between structures is simpler, and the occupied space is smaller.
[0046] As shown in the embodiments of Figures 6 to 7 The feedback device 6 comprises an electronic device 61, which is arranged on the moving path 43 of the connecting rod 3.
[0047] In some embodiments, the electronic device 61 is a micro switch, which is arranged at the end of the moving path 43 of the connecting rod 3, and is usually arranged on the side of the connecting rod 3 close to the rotating hook 4. When the rotating hook 4 is hooked with the pin shaft 1, the connecting rod 3 is adapted to be close to the micro switch and trigger the micro switch. When the micro switch is triggered, a feedback signal is sent to the user's mobile phone or the sound on the seat, etc., to facilitate the user to confirm the hooking state between the rotating hook 4 and the pin shaft 1.
[0048] As shown in the embodiments of Figure 1 and 8 The feedback device 6 comprises an observation window 62 and a plurality of indication marks 63. The observation window 62 is arranged on the base 2, and the indication marks 63 are arranged on the connecting rod 3. The indication marks 63 are sequentially distributed along the sliding direction of the connecting rod 3. The connecting rod 3 is adapted to slide relative to the base 2 and expose different indication marks 63 in the observation window 62, thereby feeding back the rotating hooking state of the rotating hook 4.
[0049] In some embodiments, the indication marks 63 are configured in different colors, for example, green and red marks can be arranged on the connecting rod 3. When the rotating hook 4 is not rotated in place, the red mark is always exposed in the observation window 62. When the rotating hook 4 is rotated in place, the red mark exposed in the observation window 62 can be replaced by the green mark with the movement of the connecting rod 3, thereby facilitating the user to observe and confirm the state between the rotating hook 4 and the pin shaft 1.
[0050] It can be understood that the moving distance of the connecting rod 3 is directly related to the exposure state of the indication marks 63 in the observation window 62. Therefore, the indication marks 63 can have a transition state to reflect the situation that the rotating hook 4 is close to the pin shaft 1 but not completely hooked with the pin shaft 1, for example, when the red and green marks exist in the observation window 62, it is the above-mentioned situation. Therefore, the scheme that the feedback device 6 comprises the observation window 62 and the plurality of indication marks 63 can more directly and timely feedback the rotating angle of the rotating hook 4, and has higher detection accuracy.
[0051] The application also provides a safety seat comprising the angle rotation detection mechanism of any of the above embodiments, the safety seat is provided with a rotatable seat on the base 2, the rotation locking of the seat is realized through the connecting and matching between the rotating hook 4 and the pin shaft 1, so as to limit the rotation and shaking action of the seat, realize the angle fixation of the seat in different directions, the angle rotation detection mechanism can detect the rotation angle of the rotating hook 4 through the movement of the connecting rod 3, so as to identify the matching degree between the rotating hook 4 and the pin shaft 1, has higher detection precision, and ensures that the correct matching between the rotating hook 4 and the pin shaft 1 occurs.
[0052] The above describes the basic principles, main features and advantages of the application, and those skilled in the art should understand that the application is not limited to the above embodiments, the above embodiments and the description in the specification are only the principles of the application, various changes and improvements can be made to the application without departing from the spirit and scope of the application, and these changes and improvements all fall within the scope of the claimed application, and the protection scope of the application is defined by the appended claims and their equivalents.
