DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0022] First embodiment:

[0023] See also Figures 1 to 3 ,in, Figure 1 is a schematic diagram of the overall structure of a car seat safety headrest according to a first embodiment of the present invention, Figure 2 is a schematic cross-sectional view along the pull-out rod 108 of the first embodiment of the present invention, Figure 3 The first embodiment of the present invention Figure 2The invention provides a car seat safety headrest, comprising a main pillow 101, a connecting rod 102, a rotating mechanism, a rotating block 103, a secondary pillow 104 and a supporting mechanism, wherein the rotating mechanism comprises a rotating rod 105, a transmission member, a transmission rod 106, a supporting plate 107, a pull-out rod 108 and a first spring 109, the transmission rod 106 comprises a first gear 110 and a second gear 111, and the supporting mechanism comprises a fixed block 112, a connecting block 113, a movable rod 114 and a moving rod 115.

[0024] In this embodiment, by arranging the connecting rod 102 below the main pillow 101, the connecting rod 102 can be inserted into the car seat, so that the main pillow 101 can be connected to the car seat and installed on the car seat, and by arranging the auxiliary pillow 104 outside the main pillow 101 and allowing the auxiliary pillow 104 to rotate outside the main pillow 101, the angle of the auxiliary pillow 104 can be adjusted, so that when passengers with different body shapes or different sitting postures use the safety headrest, their heads can effectively rest on the auxiliary pillow 104, thereby improving the use effect of the safety headrest by the passengers, and solving the technical problem that the existing safety headrest can only adjust the height up and down but not the angle of the headrest, resulting in that when passengers with different body shapes or different sitting postures use the safety headrest, their heads cannot effectively rest on the safety headrest, thereby reducing the use effect of the safety headrest by the passengers.

[0025] Among them, the number of the connecting rods 102 is two, and they are respectively arranged on the left and right sides below the main pillow 101. The connecting rod 102 is used to be inserted into the car seat and connected to the car seat. The rotating mechanism is located on the side of the main pillow 101 away from the connecting rod 102, and is used to rotate the rotating block 103. The rotating block 103 is partially located in the main pillow 101 and partially extends out of the main pillow 101. The auxiliary pillow 104 is arranged on the side of the rotating block 103 away from the main pillow 101. The supporting mechanism is arranged between the main pillow 101 and the auxiliary pillow 104, and is used to support the auxiliary pillow 104.

[0026] Secondly, a plurality of fixing slots 116 are evenly distributed outside the connecting rod 102, and the fixing slots 116 are used to be fixed with buckles in the car seat. By engaging the buckles of the car seat with the fixing slots 116 at different heights, the height of the main pillow 101 can be adjusted.

[0027] Again, the rotating rod 105 is arranged in the rotating block 103 and passes through the main pillow 101. The transmission rod 106 is used to transmit the rotational force of the rotating rod 105 to the transmission rod 106. The transmission rod 106 is located on the side of the transmission member away from the rotating rod 105. The first gear 110 is arranged outside the rotating rod 105 and located in the main pillow 101. The second gear 111 is meshed with the first gear 110 and is arranged outside the transmission rod 106. The auxiliary pillow 104 is rotated, thereby driving the rotating block 103 to rotate, and then driving the rotating rod 105 to rotate along its own axis in the main pillow 101. The rotation of the pillow 101 along its own axis can drive the first gear 110 to rotate along the axis of the rotating rod 105, and then drive the second gear 111 to rotate along the axis of the transmission rod 106. The rotation of the second gear 111 along the axis of the transmission rod 106 can drive the transmission rod 106 to rotate along its own axis in the main pillow 101. Since the rotation of the auxiliary pillow 104 on the main pillow 101 is achieved by the meshing of the teeth between the first gear 110 and the second gear 111, it can ensure that the process of adjusting the angle of the auxiliary pillow 104 is smoother, providing a more comfortable use experience for passengers.

[0028] At the same time, the support plate 107 is arranged outside the main pillow 101, the pull-out rod 108 is slidably connected with the support plate 107 and the transmission rod 106 respectively, the pull-out rod 108 passes through the support plate 107 and the transmission rod 106 respectively, the first spring 109 is arranged between the support plate 107 and the end of the pull-out rod 108, the first spring 109 is sleeved outside the rod portion of the pull-out rod 108, the transmission rod 106 is evenly distributed with through holes, the support plate 107 has an opening, the through hole size of the transmission rod 106 is consistent with the opening size of the support plate 107, and the rod portion of the pull-out rod 108 can be It is inserted into the opening of the support plate 107 and the through hole of the transmission rod 106 in sequence, so that the rotation position of the transmission rod 106 is limited and fixed. When the end of the pull-out rod 108 is pulled outward, the rod portion of the pull-out rod 108 will move in the direction away from the transmission rod 106, thereby driving the first spring 109 to be stretched. Since the first spring 109 has a self-restoring effect, when the end of the pull-out rod 108 is released, the first spring 109 will drive the end of the pull-out rod 108 to move in the direction of returning to its original position, thereby driving the rod portion of the pull-out rod 108 to move in the direction of returning to its original position.

[0029] In addition, the main pillow 101 and the auxiliary pillow 104 both have a groove 117, the fixed block 112 and the connecting block 113 are respectively arranged in the grooves 117 of the main pillow 101 and the auxiliary pillow 104, the movable rod 114 is movably connected to the fixed block 112, the moving rod 115 is movably connected to the connecting block 113, and the movable rod 114 and the moving rod 115 are movably connected, the fixed block 112, the movable rod 114, the moving rod 115 and the connecting block 113 together constitute a connecting rod mechanism, so that after the angle of the auxiliary pillow 104 is adjusted, the auxiliary pillow 104 can be supported by the connecting rod mechanism to prevent the auxiliary pillow 104 from returning to its original position.

[0030] Finally, the fixed block 112 and the movable rod 114 , the connecting block 113 and the moving rod 115 , and the movable rod 114 and the moving rod 115 are all connected via connecting pins 118 , so that the movable rod 114 and the moving rod 115 can move freely.

[0031] When using a car seat safety headrest of the present embodiment, the connecting rod 102 is inserted into the car seat, and the slot of the car seat is engaged with the fixed slot 116, so that the main pillow 101 can be connected to the car seat through the connecting rod 102, and the safety headrest can be installed on the car seat. During the installation of the safety headrest, the buckle of the car seat is engaged with the fixed slot 116 at different heights, so that the height of the main pillow 101 can be adjusted according to the height of the passenger, so that the heads of passengers of different heights can be prevented from resting on the auxiliary pillow 104.

[0032] When the angle of the auxiliary pillow 104 needs to be adjusted, the end of the pull-out rod 108 is pulled outward, so that the rod portion of the pull-out rod 108 moves in the direction away from the transmission rod 106, thereby driving the first spring 109 to be stretched. When the rod portion of the pull-out rod 108 moves out of the through hole of the transmission rod 106, the fixed state of the transmission rod 106 is released. Thereafter, the auxiliary pillow 104 is rotated, thereby driving the rotating block 103 to rotate, and further driving the rotating rod 105 to rotate along its own axis in the main pillow 101. Through the rotation of the rotating rod 105 along its own axis in the main pillow 101, Thereby, the first gear 110 can be driven to rotate along the axis of the rotating rod 105, and then the second gear 111 can be driven to rotate along the axis of the transmission rod 106. The rotation of the second gear 111 along the axis of the transmission rod 106 can drive the transmission rod 106 to rotate along its own axis in the main pillow 101. Since the rotation of the auxiliary pillow 104 on the main pillow 101 is achieved by the meshing of the teeth between the first gear 110 and the second gear 111, it can ensure that the process of adjusting the angle of the auxiliary pillow 104 is smoother, providing passengers with a more comfortable use experience.

[0033] When the auxiliary pillow 104 is rotated to a suitable angle, the end of the pull-out rod 108 is released so that the tensile force on the first spring 109 disappears, so that the first spring 109 drives the end of the pull-out rod 108 to move in the direction of returning to its original position, and then drives the rod portion of the pull-out rod 108 to move in the direction of returning to its original position. When the rod portion of the pull-out rod 108 is inserted into the through hole of the transmission rod 106, the rotation position of the transmission rod 106 is limited and fixed, so that the rotation position of the auxiliary pillow 104 is limited and fixed to avoid accidentally touching the auxiliary pillow 104 and causing the angle of the auxiliary pillow 104 to be adjusted. At the same time, the auxiliary pillow 104 can be supported by the connecting rod mechanism to prevent the auxiliary pillow 104 from returning to its original position, thereby further improving the supporting force of the auxiliary pillow 104.

[0034] Second embodiment:

[0035] Based on the first embodiment, please refer to Figure 4 and Figure 5 , Figure 4 2 is a schematic structural diagram of a cushioning mechanism of a car seat safety headrest according to a second embodiment of the present invention. Figure 5 The second embodiment of the present invention Figure 4 The enlarged view of point B of the present invention shows that a car seat safety headrest also includes a buffer mechanism, and the buffer mechanism includes an energy absorption plate 201, a second spring 202 and a buffer plate 203.

[0036] In this embodiment, the buffer mechanism is located in the auxiliary pillow 104 and is used to buffer the impact force on the passenger's head when the passenger is hit.

[0037] Among them, the auxiliary pillow 104 also has a placement groove 204, and the energy absorption plate 201, the second spring 202 and the buffer plate 203 are arranged in the placement groove 204 of the auxiliary pillow 104 from left to right in sequence. The second spring 202 is provided with a damper. When the buffer plate 203 is impacted, the buffer plate 203 will generate an impact force toward the main pillow 101, so that the second spring 202 will be compressed. Since the second spring 202 is provided with a damper, the second spring 202 will generate a damping force to prevent the second spring 202 from being compressed, so that the second spring 202 will buffer the buffer plate 203, and then the second spring 202 can buffer the head of the passenger leaning on the auxiliary pillow 104, thereby protecting the passenger's head. When the second spring 202 cannot prevent the impact force, the energy absorption plate 201 will deform when absorbing the kinetic energy of the impact force, thereby further protecting the passenger's head.

[0038] When using a car seat safety headrest of the present embodiment, when a passenger is hit, the passenger's head will generate an impact force toward the main pillow 101, so that the auxiliary pillow 104 will generate an impact force toward the main pillow 101, so that the buffer plate 203 will generate an impact force toward the main pillow 101, and then the second spring 202 will be compressed. Since the second spring 202 is provided with a damper, the second spring 202 will generate a damping force to prevent the second spring 202 from being compressed, so that the second spring 202 will buffer the buffer plate 203, and then the second spring 202 can buffer the head of the passenger leaning on the auxiliary pillow 104, thereby protecting the passenger's head. When the second spring 202 cannot prevent the impact force, the energy absorption plate 201 will deform when absorbing the kinetic energy of the impact force, thereby further protecting the passenger's head.
