For convenience of explanation, the first state described in this embodiment is also the hidden state as shown in fig. 10, and the second state is also the used state as shown in fig. 12.

Specifically, referring to fig. 2, 3 and 4, the hidden pull-out door handle 100 includes a base assembly 110, a rotating bracket 120, a handle body 150 and a spring fastener 160, wherein the rotating bracket 120 in fig. 2 and 3 is in a first state.

Further, as shown in fig. 4, the base assembly 110 includes a base frame 111, a fixing lug 116 is disposed on an edge of the base frame 111, the base frame 111 and the door 200 are installed and connected through the fixing lug 116, and in addition, the installation and connection manner of the base frame 111 may also be other manners, such as adhesion, snap, magnetic attraction, and the like.

Further, a window 112 is formed on the base frame 111, the rotating bracket 120 is rotatably disposed in the window 112 of the base frame 111, and in order to enable the rotating bracket 120 to rotate, the rotating shaft 130 is disposed at both ends of the rotating bracket 120, the rotating hole 113 is formed on the base frame 111, and the rotating bracket 120 is switched from the first state to the second state when in use.

In order to ensure that the handle body 150 can be leaked out after the rotation of the rotation bracket 120 and the user can grip the handle body 150 to open the door, the handle body 150 is disposed inside the rotation bracket 120, and further, in order to unlock the door by the pull-out handle body 150, the pull-out handle body 150 and the rotation bracket 120 are designed to be in a sliding connection.

In a preferred example of the present invention, the sliding connection between the handle body 150 and the rotating bracket 120 is as follows: be equipped with spacing spout 123 at the looks remote site of runing rest 120, set up the spacing slider 151 of outside extension at the both ends of handle body 150 for spacing slider 151 can the joint in spacing spout 123.

Further preferably, as shown in fig. 5 and 6, the handle body 150 can be drawn out of the outer side of the rotating bracket 120 in the second state, so as to avoid the phenomenon of mechanical locking of the handle body 150 in the drawing process, therefore, the number of the limiting sliding grooves 123 at each end of the rotating bracket 120 is two, and at this time, the limiting sliding blocks 151 should correspond to the number of the limiting sliding grooves 123, i.e., two, so as to ensure the stability of the handle body 150 in drawing, avoid the locking condition, and facilitate smooth unlocking and opening of the vehicle door.

In a preferred example of the present invention, please refer to fig. 7 and 8, the spring fastener 160 is disposed on the top of the rotating bracket 120, the spring fastener 160 is connected to the handle body 150 through an elastic member (not shown), the elastic member can act on the handle body 150 to make the handle body 150 always have a tendency to retract into the inside of the rotating bracket 120, so that the handle body 150 can automatically return to retract after being pulled out, and the hidden closing of the handle body 150 is prevented from being obstructed.

Therefore, the handle body 150 is arranged on the rotating bracket 120 through the elastic piece, so that the handle body 150 can be pulled out when in use and can be reset to the initial state when not in use, the rotating bracket 120 is rotationally arranged on the base frame 111, so that the rotating bracket 120 can cover the window 112 when in the first state, the window 112 is opened when in the second state, and the handle body 150 is pulled out to unlock the automobile door.

In some examples of the invention, as shown in fig. 5, in order to ensure that the rotating bracket 120 can cover the window 112 after being turned over for hiding, the rotating bracket 120 includes a hiding baffle 121, and the hiding baffle 121 is arranged to cover the window 112 in the first state.

In some examples of the present invention, referring to fig. 5 to 8, in order to facilitate the opening of the limiting sliding groove 123 on the rotating bracket 120 for the sliding installation of the handle body 150, therefore, the rotating bracket 120 further includes two rotating blocks 122 disposed oppositely, the rotating blocks 122 are disposed on the inner side surface of the hidden baffle 121, a cavity for accommodating the handle body 150 is formed between the opposite rotating blocks 122, the rotating blocks 122 are provided with the limiting sliding groove 123, the handle body 150 is provided with the limiting sliding block 151, and the limiting sliding block 151 is slidably disposed in the limiting sliding groove 123, so as to enable the handle body 150 to slide relative to the rotating blocks 122.

With reference to fig. 5, since the rotating blocks 122 are disposed at the inner sides of the two ends of the hidden baffle 121, in order to ensure the stability of the rotating bracket 120 during rotation, the rotating shaft 130 is disposed on the outer wall of the rotating blocks 122, and then the rotating shaft 130 is rotatably inserted into the rotating hole 113.

Referring to fig. 4, in the rotation process of the rotating bracket 120, a certain limitation needs to be made on the revolute pair of the rotating bracket 120, so as to avoid that the rotating bracket 120 rotates over the head and cannot achieve the effects of hiding and reducing wind resistance, for this reason, a lower stop strip 114 and an upper stop strip 115 need to be arranged inside the window 112 of the base frame 111, and the lower stop strip 114 and the upper stop strip 115 can be used for limiting the revolute pair of the rotating bracket 120 in the first state or the second state, specifically, in the first state, the lower stop strip 114 acts on the lower edge of the hidden baffle 121 to play a role of blocking, that is, the lower edge of the hidden baffle 121 cannot rotate into the inside of the window 112, and in the second state, the upper stop strip 115 acts on the outer surface of the hidden baffle 121 to play a role of blocking, at this time, the hidden baffle 121 cannot be turned upwards, and the pull-out handle body 150 can open the vehicle door.

In some examples of the present invention, as shown in fig. 6 to 8, in order to allow the handle body 150 to be automatically returned and retracted after the handle body 150 is drawn out, a connection fastener 152 is provided at an upper edge of the handle body 150, and an end of the spring fastener 160 in the first state is extended above the connection fastener 152, and an elastic member is provided between the connection fastener 152 and the spring fastener 160.

In a preferred embodiment, the elastic member is a spring.

As shown in fig. 3 and 9, in order to realize the automatic rotation of the rotating bracket 120, the hidden pull-out door handle of the present invention further includes a driving mechanism 140, which is used for switching the rotating bracket 120 between the first state and the second state by the driving mechanism 140 acting on the rotating shaft 130, so as to achieve the purpose of automatically opening the window 112.

In some examples of the present invention, the driving mechanism 140 includes a speed reducer 141, an output end of the speed reducer 141 is provided with a first driving wheel 142, the rotating shaft 130 is provided with a second driving wheel 143, the first driving wheel 142 is in driving connection with the second driving wheel 143, wherein both the first driving wheel 142 and the second driving wheel 143 are driving gears, and the first driving wheel 142 and the second driving wheel 143 are in meshing transmission.

In other examples of the present invention, the first transmission wheel 142 and the second transmission wheel 143 may also be a sprocket wheel or a pulley wheel, and may be respectively transmitted by a chain or a belt, and may be selected according to the vehicle type and the space inside the door.
