Description

Technical Field

[0001] This invention relates to the field of automotive seat headrest technology, and more particularly to an internal mounting structure for an automotive seat headrest. Background Technology

[0002] The headrest is an important component of a car seat, consisting of a frame and cushioning components covering the outside of the frame. The main function of a car seat headrest is to prevent the cervical spine of passengers in front of the vehicle from being injured due to inertia in the event of a rear-end collision or other safety accident.

[0003] The utility model patent with publication number CN210912129U discloses an air-purifying car seat headrest, which uses an air purifier fixed in the headrest frame assembly to purify the air in the car, eliminate odors, and improve the air quality inside the car.

[0004] In the above technical solution, in order to facilitate the installation of the air purifier inside the frame, the frame is designed to interlock with the frame assembly and the headrest back cover. In the event of damage to the air purifier, the frame assembly and the headrest back cover need to be disassembled. However, the commonly used headrest frame interlocking structure is prone to breakage when the two are disassembled, which will affect the assembly operation and assembly firmness of the headrest. Summary of the Invention

[0005] In view of this, the present invention proposes an internal mounting structure for a car seat headrest, which, while ensuring the firmness of the first frame and the second frame, allows for easy assembly and disassembly of the two.

[0006] The technical solution of this invention is implemented as follows: This invention provides an internal mounting structure for a car seat headrest, including a first frame and a second frame, wherein,

[0007] A ring plate is fixedly installed on the first frame;

[0008] The second frame is disposed on one side of the first frame. A fixing seat is fixedly disposed on the second frame. An elastic latch is fixedly disposed on the fixing seat. The fixing seat passes through the ring plate and is slidably connected to it. The elastic latch abuts against the side of the ring plate away from the second frame. The distance from the end of the elastic latch abutting against the ring plate to the ring plate gradually increases along the direction from the center line of the fixing seat to the periphery of the fixing seat.

[0009] Based on the above technical solutions, preferably, an elastic plate is fixedly provided between the fixed base and the elastic latch.

[0010] More preferably, it also includes a limiting plug, which is fixedly disposed on the side of the fixed seat away from the second skeleton. A supporting rod is fixedly disposed on the limiting plug, which passes through the fixed seat and abuts against the elastic latch and the elastic plate respectively.

[0011] More preferably, a fixing post is fixedly provided on the limiting plug, the fixing post passing through the fixing seat and abutting against the side of the elastic plate away from the abutting rod.

[0012] More preferably, a wedge is fixedly provided on the fixed column, and the wedge abuts against the side of the elastic plate away from the abutting rod.

[0013] Based on the above technical solutions, preferably, the fixing base includes a rectangular tube, a fixing rod, and a rubber plate, wherein,

[0014] The elastic latch is fixedly mounted on the rectangular tube, and the rectangular tube passes through the annular plate and is slidably connected to it;

[0015] One end of the fixing rod is fixedly mounted on the second frame;

[0016] The rubber plate is fixedly installed at the end of the fixing rod away from the second frame and is fixedly connected to the rectangular tube.

[0017] More preferably, a support plate is fixedly provided on the side of the elastic latch near the center line of the rectangular tube;

[0018] The rubber plate is disposed at one end of the rectangular tube away from the second skeleton, and selectively abuts against the end of the support plate away from the elastic latch, and the tensile force on the rubber plate when it deforms is not less than the tensile force on the elastic latch when it deforms.

[0019] More preferably, a sliding frame is fixedly provided on the second skeleton, and the rectangular tube is slidably connected to the sliding frame.

[0020] Based on the above technical solution, preferably, the first frame is provided with a plurality of ring plates, and the second frame is provided with a plurality of fixing seats, wherein the number and position of the ring plates and the fixing seats correspond one-to-one;

[0021] Each of the fixed seats has a plurality of elastic latches arranged in a circumferential manner.

[0022] More preferably, the distance from the end of the fixing seat away from the second frame to the second frame is less than the distance from the side of the first frame away from the second frame to the second frame.

[0023] The automotive seat headrest internal mounting structure of the present invention has the following advantages over the prior art:

[0024] (1) By setting a ring plate and a fixed seat, and setting an elastic latch on the fixed seat, the ring plate and the fixed seat can be easily fixed. By setting the abutting end of the elastic latch to be inclined, the elastic latch can be prevented from being damaged when the fixed seat and the ring plate are separated, so that the first frame and the second frame can be easily disassembled and assembled.

[0025] (2) By setting up elastic plates and limiting plugs, the tongue can be supported and fixed, the fixing of the first frame and the second frame can be strengthened, and the fixing seat and the ring plate can be prevented from separating due to external force.

[0026] (3) By setting a support plate and setting the fixing seat to include a rectangular tube, a fixing rod and a rubber plate, the elastic change of the elastic latch after being subjected to force and the elastic change of the rubber plate after being subjected to force can make the first frame and the second frame easy to separate under a specified force, thereby avoiding the separation of the first frame and the second frame due to misoperation.

[0041] The technical solutions of this invention will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0042] Example 1

[0043] like Figures 1-7 As shown, an internal mounting structure for a car seat headrest according to the present invention includes a first frame 1, a second frame 2, and a limiting plug 3.

[0044] The seat headrest assembly consists of two parts, with the first frame 1 being one of them.

[0045] The second frame 2 is another part of the seat headrest. A ring plate 11 is fixedly installed on the first frame 1. The second frame 2 is located on one side of the first frame 1. A fixing seat 21 is fixedly installed on the second frame 2. An elastic latch 2111 is fixedly installed on the fixing seat 21. The fixing seat 21 passes through the ring plate 11 and is slidably connected to it. Figure 6 As shown, the elastic latch 2111 abuts against the side of the ring plate 11 away from the second frame 2, thereby connecting and fixing the first frame 1 and the second frame 2. Since the first frame 1 and the second frame 2 need to be disassembled during use, to prevent the ring plate 11 from breaking the elastic latch 2111 during this disassembly process, it is preferable that the distance from the end of the elastic latch 2111 abutting against the ring plate 11 to the ring plate 11 gradually increases along the direction from the center line of the fixing seat 21 to the periphery of the fixing seat 21. Figure 6 As shown, the lower end of the elastic latch 2111 is set to an inclined shape. When the fixing seat 21 moves downward, this inclined surface can be used to allow the elastic latch 2111 to retract into the fixing seat 21, so as to avoid damage and affect the reassembly of the headrest.

[0046] To improve the fixation of the first frame 1 and the second frame 2 and prevent abnormal noise during use, it is preferable to set multiple ring plates 11 on the first frame 1 and multiple fixing seats 21 on the second frame 2, so that the number and position of the ring plates 11 and the fixing seats 21 correspond one-to-one; similarly, multiple elastic latches 2111 can also be set in a circular arrangement on each fixing seat 21.

[0047] In order to avoid the fixed seat 21 protruding from the surface of the first frame 1 and affecting the user's experience, it is preferable that the distance from the end of the fixed seat 21 away from the second frame 2 to the second frame 2 is less than the distance from the side of the first frame 1 away from the second frame 2 to the second frame 2.

[0048] Since the abutting end of the elastic latch 2111 is inclined, the first frame 1 and the second frame 2 will separate after being subjected to a small external force. In order to improve its fixation firmness, it is preferable to fix an elastic plate 2112 between the fixing seat 21 and the elastic latch 2111 to enhance its anti-deformation effect.

[0049] The limiting plug 3 is used to prevent the first frame 1 and the second frame 2 from separating. The limiting plug 3 is fixedly installed on the side of the fixed seat 21 away from the second frame 2. A supporting rod 31 is fixedly installed on the limiting plug 3. The supporting rod 31 passes through the fixed seat 21 and abuts against the elastic latch 2111 and the elastic plate 2112 respectively. Figure 7As shown, when the first frame 1 and the second frame 2 are connected and fixed, the limiting plug 3 is installed on the fixed base 21, and the supporting rod 31 can be used to support the elastic latch 2111 and the elastic plate 2112 to prevent them from deforming. When it is necessary to separate the first frame 1 and the second frame 2, the limiting plug 3 can be removed.

[0050] To enhance the supporting effect of the limiting plug 3 on the fixed seat 21, it is preferable to fix a fixing post 32 on the limiting plug 3, allowing the fixing post 32 to penetrate the fixed seat 21 and abut against the side of the elastic plate 2112 away from the supporting rod 31; similarly, a wedge block 321 can also be fixedly installed on the fixing post 32, allowing the wedge block 321 to abut against the side of the elastic plate 2112 away from the supporting rod 31, such as... Figure 7 As shown, while using the wedge block 321 to hold and fix the elastic plate 2112, it can also prevent the limiting plug 3 from falling off the fixed seat 21.

[0051] The method of using the internal mounting structure of a car seat headrest according to this embodiment of the invention is as follows:

[0052] When it is necessary to disassemble the first frame 1 and the second frame 2, first remove the limiting plug 3 from the fixing seat 21, and then forcefully separate the first frame 1 and the second frame 2; when it is necessary to install the first frame 1 and the second frame 2, first use the fixing seat 21 and the elastic latch 2111 to cooperate with the ring plate 11 to fix the first frame 1 and the second frame 2, and then insert the limiting plug 3 into the fixing seat 21 so that it abuts against the elastic latch 2111 and the elastic plate 2112.

[0053] Example 2

[0054] like Figures 1-2 , Figures 8-12 As shown, an internal mounting structure for a car seat headrest according to the present invention includes a first frame 1 and a second frame 2.

[0055] The seat headrest assembly consists of two parts, with the first frame 1 being one of them.

[0056] The second frame 2 is another part of the seat headrest. A ring plate 11 is fixedly installed on the first frame 1. The second frame 2 is located on one side of the first frame 1. A fixing seat 21 is fixedly installed on the second frame 2. An elastic latch 2111 is fixedly installed on the fixing seat 21. The fixing seat 21 passes through the ring plate 11 and is slidably connected to it. Figure 6As shown, the elastic latch 2111 abuts against the side of the ring plate 11 away from the second frame 2, thereby connecting and fixing the first frame 1 and the second frame 2. Since the first frame 1 and the second frame 2 need to be disassembled during use, to prevent the ring plate 11 from breaking the elastic latch 2111 during this disassembly process, it is preferable that the distance from the end of the elastic latch 2111 abutting against the ring plate 11 to the ring plate 11 gradually increases along the direction from the center line of the fixing seat 21 to the periphery of the fixing seat 21. Figure 6 As shown, the lower end of the elastic latch 2111 is set to an inclined shape. When the fixing seat 21 moves downward, this inclined surface can be used to allow the elastic latch 2111 to retract into the fixing seat 21, so as to avoid damage and affect the reassembly of the headrest.

[0057] To improve the fixation of the first frame 1 and the second frame 2 and prevent abnormal noise during use, it is preferable to set multiple ring plates 11 on the first frame 1 and multiple fixing seats 21 on the second frame 2, so that the number and position of the ring plates 11 and the fixing seats 21 correspond one-to-one; similarly, multiple elastic latches 2111 can also be set in a circular arrangement on each fixing seat 21.

[0058] In order to avoid the fixed seat 21 protruding from the surface of the first frame 1 and affecting the user's experience, it is preferable that the distance from the end of the fixed seat 21 away from the second frame 2 to the second frame 2 is less than the distance from the side of the first frame 1 away from the second frame 2 to the second frame 2.

[0059] The fixing base 21 is preferably configured to include a rectangular tube 211, a fixing rod 212, and a rubber plate 213. The elastic latch 2111 is fixedly mounted on the rectangular tube 211, and the rectangular tube 211 passes through the ring plate 11 and is slidably connected to it. One end of the fixing rod 212 is fixedly mounted on the second frame 2, and the rubber plate 213 is fixedly mounted on the end of the fixing rod 212 away from the second frame 2 and is fixedly connected to the rectangular tube 211. When the first frame 1 and the second frame 2 are subjected to an external force that separates them, the second frame 2 drives the fixing rod 212 and the rubber plate 213 to move, thereby causing the elastic latch 2111 on the rectangular tube 211 to slide against the side wall of the ring plate 11, so that the elastic latch 2111 is separated from the ring plate 11.

[0060] Since the abutting end of the elastic tongue 2111 is inclined, the first frame 1 and the second frame 2 will separate under a relatively small external force. To improve the firmness of their fixation, it is preferably provided with a support plate 2113 on the side of the elastic tongue 2111 close to the center line of the rectangular tube 211. The rubber plate 213 is arranged at one end of the rectangular tube 211 away from the second frame 2 and selectively abuts against the end of the support plate 2113 away from the elastic tongue 2111. The tensile force received by the rubber plate 213 during deformation should not be less than the tensile force received by the elastic tongue 2111 during deformation. For example, the minimum tensile force received by the rubber plate 213 during deformation is A, the minimum tensile force received by the elastic tongue 2111 during deformation is B, and the separating force on the first frame 1 and the second frame 2 is C. As shown in the figure, if C > A, it will cause the rubber plate 213 to deform, making the rubber plate 213 abut against the elastic plate 2112, so that the elastic tongue 2111 is inconvenient to shrink into the rectangular tube 211. If C < B, the elastic tongue 2111 will not shrink into the rectangular tube 211 due to too small force. Therefore, when B ≤ C < A, it is convenient to pull out the fixing seat 21 from the ring plate 11. Thus, by selecting the materials of the rubber plate 213 and the elastic tongue 2111, the disassembly force of the first frame 1 and the second frame 2 can be restricted, so as to achieve a certain anti-misoperation effect.

[0061] To avoid the rectangular tube 211 from skewing during the disassembly and assembly of the first frame 1 and the second frame 2, it is preferably provided with a sliding frame 22 fixed on the second frame 2, and the rectangular tube 211 is slidably connected to the sliding frame 22.

[0062] The usage method of an internal installation structure of an automotive seat headrest according to an embodiment of the present invention is as follows:

[0063] When it is necessary to disassemble the first frame 1 and the second frame 2, the splitting force on the two can be controlled between the tensile force received by the rubber plate 213 during deformation and the tensile force received by the elastic tongue 2111 during deformation; when it is necessary to install the first frame 1 and the second frame 2, the rectangular tube 211 and the elastic tongue 2111 can be directly fixed in cooperation with the ring plate 11.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
