Description

Technical Field

[0001] This utility model relates to the field of headrest speaker technology, specifically a replaceable headrest speaker for automobile seats. Background Technology

[0002] With the booming development of the automotive industry, users have increasingly higher requirements for the sound quality inside cars. Currently, most high-end models on the market are equipped with headrest speakers for playing navigation, calls, alert tones, and music.

[0003] For example, the announcement number CN222053364U describes a replaceable headrest speaker for car seats. In actual use, the bracket is inserted into the seat, and the bottom of the bracket is inserted into the connecting sleeve. Then, by rotating the torsion column, the first gear is rotated, which causes the second gear to drive the inner shaft and the third gear to rotate. This causes the gear plate to push the movable plate to both sides, allowing the fixed protrusion to be inserted into the middle of the fixing hole to connect the power cord, thus completing the installation. Then, the push column is pulled down to insert the positioning rod into the positioning hole, which can be used to position and prevent loosening, making the installation more stable. It can be customized to meet different user needs and preferences, and it is more convenient to replace and clean the headrest speaker.

[0004] The patent requires that when disassembling the headrest speaker, the locking lever must first be released from the headrest's limiting position, then the knob is turned to drive the transmission component to move, causing the locking block to disengage from the bracket, and then the headrest speaker is separated from the bracket. This method of disassembling the headrest speaker is rather cumbersome and inconvenient for disassembling the headrest speaker. Utility Model Content

[0005] The purpose of this invention is to provide a replaceable headrest speaker for automobile seats, so as to solve the problem mentioned in the background art that existing headrest speakers are not easy to disassemble.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a replaceable headrest speaker for automobile seats, comprising: a connecting frame and a speaker body, wherein a bracket is slidably connected to the top of the connecting frame, the headrest body is disposed on the top of the bracket, and speaker bodies are mounted on both sides of the headrest body.

[0007] The top of the connecting frame is provided with a limiting mechanism, which includes a push rod that is slidably connected to the inside of the bracket. One end of the push rod is movably connected to a connecting rod a via a rotating shaft. One end of the connecting rod a is movably connected to a connecting rod b via a rotating shaft. One end of the connecting rod b is movably connected to a connecting rod c via a rotating shaft. One end of the connecting rod c is movably connected to a push plate via a rotating shaft.

[0010] Specifically, the sliders on both sides of the push plate can limit its range of movement and prevent it from moving out of the support.

[0011] Preferably, a spring a is fixedly connected inside the connecting frame, and a locking block is fixedly connected to one end of the spring a.

[0012] Specifically, spring a can push the card block to reset.

[0013] Preferably, one side of the card block is engaged with the bracket, and the outer side of the card block is slidably connected to the connecting frame.

[0014] Preferably, a spring b is sleeved on the outer side of the push rod, and one end of the spring b abuts against the bracket.

[0015] Specifically, spring b can push the push rod to reset.

[0016] Preferably, the adjustment mechanism includes a handle that is movably connected to the headrest body via a bearing.

[0017] Preferably, two sets of bevel gears a are fixedly connected to the outer side of the handle, and bevel gears b are meshed with the outer sides of the two sets of bevel gears a.

[0018] Specifically, the handle can drive two sets of bevel gears a to mesh with two sets of bevel gears b.

[0019] Preferably, a threaded rod is fixedly connected to one side of the bevel gear b, the top of the threaded rod is movably connected to the headrest body through a bearing, and the outer side of the threaded rod is threadedly connected to the bracket.

[0020] Specifically, bevel gear b can drive the threaded rod and the bracket to perform threaded transmission, thereby driving the headrest speaker to move.

[0021] Compared to existing technologies, the advantages of this replaceable headrest speaker for car seats are:

[0022] 1. This replaceable headrest speaker for car seats allows for easy replacement of the headrest speaker when the headrest body is removed and replaced. Pushing the push rod compresses a spring (b) on one side, causing a connecting rod (a) to rotate. The rotation of connecting rod (a) pushes the bottom connecting rod (b) downwards. The movement of connecting rod (b) then rotates connecting rod (c), causing a push plate at one end of connecting rod (c) to move. The push plate then pushes a locking block out of the bracket, allowing the headrest body to separate from the connecting frame, thus completing the disassembly of the headrest body. This operation facilitates the replacement of the headrest speaker.

[0023] 2. This replaceable headrest speaker for car seats allows for height adjustment of the headrest body by turning the handle. The handle engages two sets of bevel gears (a and b), causing the bevel gears (b) to rotate. These bevel gears (b) then drive two sets of threaded rods to rotate synchronously, creating a threaded transmission with the bracket. This changes the height of the headrest body. Once adjustment is complete, releasing the handle locks the threaded rods to the bracket, fixing the headrest body in place. This operation facilitates easy height adjustment of the headrest speaker.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 This utility model provides a technical solution: a replaceable headrest speaker for a car seat, comprising: a connecting frame 1 and a speaker body 4, a bracket 2 slidably connected to the top of the connecting frame 1, a headrest body 3 disposed on the top of the bracket 2, and speaker bodies 4 mounted on both sides of the headrest body 3.

[0031] A limiting mechanism 5 is provided at the top of the connecting frame 1. The limiting mechanism 5 includes a push rod 501 that is slidably connected to the inside of the bracket 2. One end of the push rod 501 is movably connected to a connecting rod a 502 via a rotating shaft. One end of the connecting rod a 502 is movably connected to a connecting rod b 503 via a rotating shaft. One end of the connecting rod b 503 is movably connected to a connecting rod c 504 via a rotating shaft. One end of the connecting rod c 504 is movably connected to a push plate 505 via a rotating shaft. An adjustment mechanism 6 is provided at the bottom of the headrest body 3.

[0032] Both sides of the push plate 505 are fixedly connected to sliders 509, and the outer side of the sliders 509 is slidably connected to the bracket 2; the inside of the connecting frame 1 is fixedly connected to a spring a507, and one end of the spring a507 is fixedly connected to a locking block 506; one side of the locking block 506 is engaged with the bracket 2, and the outer side of the locking block 506 is slidably connected to the connecting frame 1; the outside of the push rod 501 is sleeved with a spring b508, one end of the spring b508 abuts against the bracket 2, and the push rod 501 forms a rotating structure with the connecting rod a502 through a rotating shaft. The inside of the connecting frame 1 is provided with a sliding groove that matches the locking block 506, and the locking block 506 and the connecting frame 1 form a sliding structure.

[0033] In practical implementation, when the replaceable headrest speaker for car seats is removed and replaced by pushing the push rod 501, the push rod 501 will compress the spring b508 on one side and drive the connecting rod a502 at one end to rotate. When the connecting rod a502 rotates, it can push the connecting rod b503 at the bottom to move down. When the connecting rod b503 moves, it can push the connecting rod c504 to rotate, causing the push plate 505 at one end of the connecting rod c504 to move. When the push plate 505 moves, it will push the locking block 506 out of the bracket 2. At this time, The movable headrest body 3 is separated from the connecting frame 1, completing the disassembly of the headrest body 3. When installing a new headrest body 3, the bracket 2 at the bottom of the headrest body 3 is inserted into the top of the connecting frame 1. When the bracket 2 contacts the inclined surface of the locking block 506, the locking block 506 will move and press the spring a507 on one side. When the locking block 506 contacts the slot inside the bracket 2, the spring a507 will push the locking block 506 to engage with the bracket 2, completing the installation of the headrest speaker. The above operation makes it easy to replace the headrest speaker.

[0034] Please see Figures 1-2The adjustment mechanism 6 includes a handle 601 that is movably connected to the headrest body 3 via a bearing; two sets of bevel gears a602 are fixedly connected to the outside of the handle 601, and bevel gears b603 are meshed on the outside of the two sets of bevel gears a602; a threaded rod 604 is fixedly connected to one side of the bevel gear b603, the top of the threaded rod 604 is movably connected to the headrest body 3 via a bearing, the outside of the threaded rod 604 is threadedly connected to the bracket 2, the bracket 2 and the threaded rod 604 form a threaded transmission structure, and the bevel gears a602 and b603 form a meshing transmission structure.

[0035] In practical implementation, when adjusting the height of the headrest body 3, the replaceable headrest speaker for car seats is adjusted by turning the handle 601. The handle 601 drives two sets of bevel gears a602 and two sets of bevel gears b603 to mesh, thereby driving the two sets of bevel gears b603 to rotate. The two sets of bevel gears b603 drive the two sets of threaded rods 604 to rotate synchronously, thereby performing threaded transmission with the bracket 2. At this time, the height of the headrest body 3 will change. After the adjustment is completed, the handle 601 can be released. At this time, the threaded rods 604 will self-lock with the bracket 2, completing the fixation of the position of the headrest body 3. In this way, the height of the headrest speaker can be easily adjusted.

[0036] In summary: When using replaceable headrest speakers for car seats, the headrest body 3 firstly supports the user's head, and the speaker bodies 4 on both sides of the headrest body 3 can play music. The contents not described in detail in this specification are prior art known to those skilled in the art.
