[0002] For tablet-type electronic devices such as mobile phones and tablets, using a stand to support or clamp them can free up the user's hands and provide convenience for the user to use these electronic devices.

[0003] However, existing stents have the following shortcomings:

[0004] 1. The clamping contact area for electronic devices is small, resulting in unreliable clamping. If the clamping area is increased, the overall size will be too large, occupying too much space.

[0005] 2. When users want to use a bracket in their car, existing brackets are generally clamped at the front of the car, which is only convenient for the driver and front passenger, and not convenient for rear passengers. Utility Model Content

[0006] The purpose of this utility model is to address the problems existing in the background technology by proposing a clamping mechanism and a hidden rear seat bracket for vehicles that can increase the clamping area when clamping electronic devices, and can be stored away when not in use to reduce the overall space occupied, and can also be used by rear passengers.

[0011] Preferably, a first connecting nut is provided at the outer end of a connecting bracket, and a second connecting nut is provided at the middle of the back of the mounting cylinder.

[0012] Preferably, a connecting rope is provided on another connecting frame.

[0013] On the other hand, this utility model proposes a hidden vehicle rear seat bracket, including the above-mentioned clamping mechanism, a mounting frame, a clamping component disposed on the mounting frame, a first connecting seat disposed at one end of the mounting frame, a storage frame disposed on the first connecting seat with one end damped and rotatable, a second connecting seat disposed on the other end of the storage frame with damped and rotatable, and a third connecting seat connecting the second connecting seat and the clamping mechanism.

[0030] Example 1

[0031] like Figures 1-4 As shown, the clamping mechanism proposed in this embodiment includes a mounting cylinder 1, an elastic tensioning component, and a clamping component, the clamping component being used to clamp electronic devices.

[0032] Both ends of the mounting cylinder 1 are equipped with sealing caps 4, and the inner side of the mounting cylinder 1 is open along its length. A mounting frame 8 can be installed inside the mounting cylinder 1 to improve structural strength.

[0033] The elastic tensioning assembly includes a slide rod 5 slidably mounted on a sealing cover 4, a connector 6 connected to one end of the slide rod 5 located inside the mounting cylinder 1, and a spring 7 sleeved on the outer periphery of the slide rod 5 and connected at both ends to the connector 6 and the sealing cover 4, respectively.

[0034] Two sets of clamping components are distributed opposite each other on both sides of the mounting cylinder 1 along its length, so that they can be clamped to both sides of the electronic device.

[0035] When one set of elastic tensioning components is provided, the two sets of clamping components are respectively connected to the outer end of the slide rod 5 and another sealing cover 4. This other sealing cover 4 is not a sealing cover 4 for the slide rod 5 to slide on. At this time, only one end of the clamping mechanism can be telescopically adjusted. When two sets of elastic tensioning components are symmetrically provided about the mounting cylinder 1, the two sets of clamping components are respectively connected to the outer end of the slide rod 5 in the two sets of elastic tensioning components. The multiple slide rods 5 in the two sets of elastic tensioning components slide on the two sealing covers 4 respectively. At this time, both ends of the clamping mechanism can be telescopically adjusted.

[0036] The clamping assembly includes a connecting frame 2 and two positioning clamps 3 symmetrically rotatably mounted on the connecting frame 2. The connecting frame 2 is connected to a slide rod 5 or a sealing cover 4. The connecting frame 2 has an abutment surface that limits the outward extension range of the positioning clamps 3. When the positioning clamps 3 extend outward to their limit position, they abut against the abutment surface.

[0037] The two clamping assemblies have two connecting frames 2. One connecting frame 2 has a first connecting nut 91 at its outer end, and the other connecting frame 2 has a connecting rope 10 for easy lifting. A second connecting nut 92 is located in the middle of the back of the mounting cylinder 1. The two connecting nuts give the clamping mechanism two connection positions, allowing for the connection of an external support structure or a clamping structure. The support structure can be placed on a table, and the clamping structure can be mounted on a table frame, bed frame, or vehicle. Regardless of whether an external support structure or a clamping structure is connected, both clamping assemblies can clamp tablet computers and other tablet-like electronic devices.

[0038] The positioning clamp 3 has a recessed clamping channel, which prevents the electronic device from easily falling off after clamping it. A mounting groove is provided at the bottom of the clamping channel, and an elastic pad 11 is provided at the mounting groove to prevent wear when clamping the electronic device. The connecting bracket 2 has a protruding locking platform 201 on the side facing the positioning clamp 3, and the positioning clamp 3 has a locking groove 301 into which the locking platform 201 can be engaged. When the positioning clamp 3 unfolds outward, the locking platform 201 engages with the locking groove 301, limiting the positioning clamp 3.

[0039] This embodiment allows the clamping assembly to be pulled from one or both sides, with the pulling distance adjustable according to the size of the electronic device. It securely clamps the electronic device from both sides, preventing it from easily falling off. Furthermore, after the positioning clamp 3 is extended outwards, it is limited by the locking plate 201 on the connecting frame 2, preventing it from moving erratically. The stable positioning clamp 3 after being extended facilitates user clamping operations on the electronic device. When extended, the positioning clamp 3 provides a large clamping area and secure hold. When not in use, the positioning clamp 3 can be rotated inwards to save space and facilitate storage.

[0040] Example 2

[0041] like Figures 1-9 As shown, the concealed rear seat bracket proposed in this embodiment includes the clamping mechanism in Embodiment 1, and also includes a mounting frame 12, a clamping assembly disposed on the mounting frame 12, a first connecting seat 13 disposed at one end of the mounting frame 12, a storage frame 14 disposed at one end of the first connecting seat 13 with damping rotatability, a second connecting seat 15 disposed at the other end of the storage frame 14 with damping rotatability, and a third connecting seat 16 connecting the second connecting seat 15 and the clamping mechanism. The storage frame 14 includes two connecting plates, forming a storage space between the two connecting plates. By rotating the clamping mechanism, the third connecting seat 16, and the second connecting seat 15, the clamping mechanism can be stored inside the storage space. Then, by rotating the storage frame 14 through the first connecting seat 13, the storage frame 14 fits against the mounting frame 12, and the entire bracket achieves neat concealed storage. The connection relationship between the third connecting seat 16, the second connecting seat 15, and the clamping mechanism is divided into the following three cases:

[0042] 1. The third connecting seat 16 is selected to be damped and rotatedly connected to the second connecting seat 15 and the clamping mechanism, that is, the third connecting seat 16 is only damped and rotatedly connected to one structure, and is detachably or fixedly connected to another structure. Specifically, the third connecting seat 16 is connected to a connecting frame 2 in the clamping mechanism.

[0043] 2. The third connecting seat 16 is not a damped rotational connection with the second connecting seat 15 and the clamping mechanism, but a detachable connection or a fixed connection. The third connecting seat 16 is specifically connected to a connecting frame 2 in the clamping mechanism.

[0044] 3. The third connecting seat 16 is simultaneously connected to the second connecting seat 15 and the clamping mechanism in a damped rotatable manner. That is, the damped rotatable mechanism is mounted on the second connecting seat 15 and is also connected to the end of a connecting frame 2 in the clamping mechanism in a damped rotatable manner. The rotational axis of the second connecting seat 15, the rotational axis of the third connecting seat 16, and the rotational axis of the connecting frame 2 are all perpendicular to each other, thereby enabling multi-directional adjustment of the electronic equipment clamped by the clamping mechanism.

[0045] In all three cases, the clamping mechanism can be deployed when in use and stored inside the storage rack 14 when not in use.

[0046] like Figures 5-7As shown, the clamping frame 12 has a laterally distributed guide rail section, and two sets of clamping components are arranged side by side, including a sliding frame 17 slidably mounted on the clamping frame 12, a clamping pad 18 mounted on the sliding frame 17, a knob 19 connected to the outer end of the sliding frame 17, and a pressure pad 20 mounted on the knob 19 and facing the clamping pad 18. Based on the two metal rods above the front seat of the car, the sliding frame 17 is adjusted on the guide rail section of the clamping frame 12 to adjust the distance between the two sliding frames 17, and the two sliding frames 17 are inserted into the two metal rods respectively. Then, the knob 19 is tightened to clamp the metal rods between the clamping pad 18 and the pressure pad 20 (or clamped onto the plastic layer surrounding the metal rods). The position of the sliding frame 17 is adjustable to accommodate front seat metal rods with different spacing. When the bracket is fully retracted, the clamping frame 12 and the storage rack 14 are located in the space between the headrest above the seat and the backrest below, without protruding from the seat, resulting in a harmonious and aesthetically pleasing overall appearance.

[0047] like Figure 7 As shown, the sliding frame 17 has a clamping channel, and the outer end of the sliding frame 17 has a threaded portion 171. There are two threaded portions 171 distributed opposite each other. The knob 19 has an internal thread that is threaded to the threaded portion 171. The seat metal rod is clamped by screwing the knob 19 onto the threaded portion 171.

[0048] like Figure 8 and Figure 9 As shown, a silicone sleeve 21 is fitted onto the storage rack 14. The silicone sleeve 21 includes two protective layers and a buffer layer integrally connected between the two protective layers, with the buffer layer protruding outwards. The silicone sleeve 21 enhances safety during use. When the rack is in its retracted state, if a rear passenger's head hits the silicone sleeve 21 on the rack, the silicone sleeve 21 provides cushioning to prevent injury.

[0049] This embodiment can be clamped onto the metal rod of the front seat of a car. The clamping mechanism can be adjusted to the appropriate position to hold electronic devices as needed, whether horizontally, vertically, or at an angle. Rear passengers can comfortably use their electronic devices after clamping them onto the mechanism. The electronic devices will not fall out after being clamped, ensuring high safety. When not in use, the bracket can be folded and stored in the area between the headrest and backrest of the seat for concealed storage.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
