Description

Technical Field

[0001] The invention belongs to the technical field of vehicle accessories, and in particular relates to a detachable bottom fixing structure for a vehicle-mounted oven. Background Art

[0002] The rise of long-distance self-driving tours has brought more freedom and fun to life. At the same time, household appliances are gradually moving towards car-mounted installations. For example, car-mounted refrigerators, ovens, and cookers are gradually becoming the new favorites of travelers. The fixation of car-mounted appliances requires consideration of flexible disassembly and assembly for different models and scenarios, and on the other hand, it is also necessary to consider the shock absorption and protection of car-mounted appliances. In addition, in order to save time, truck drivers of long-distance logistics transportation often use rice cookers and ovens in the cab to solve the problem of eating. In addition, car-mounted appliances are often in use while driving, and the problem of vehicle bumps also poses new challenges to the installation and fixation of car-mounted appliances.

[0003] Common fixing methods include adhesive, suction cup, and clip types. However, these common fixing methods are not effective when installing larger electrical appliances because the appliances themselves are heavy and large in size, and are also affected by factors such as vehicle bumps and vibrations.

[0004] Chinese patent document with publication number CN114148238B discloses a multifunctional vehicle-mounted refrigerator and its connecting seat, including a refrigerator and a connecting seat, wherein the refrigerator is arranged above the connecting seat, a movable door is hinged on the front wall of the refrigerator by hinges, a handle is fixedly installed on the top of the refrigerator, a pull-out storage drawer is arranged on the bottom inner wall of the refrigerator, two partitions are arranged above the storage drawers corresponding to the interior of the refrigerator, and a cleaning device for cleaning the surface of the partition is arranged above the partition. The multifunctional vehicle-mounted refrigerator and its connecting seat place the bottom block on the bottom surface behind the vehicle, the base on the rear seat, and then rotate the threaded column to adjust the length of the threaded column extending out of the outside of the column to keep the base in a horizontal state, and then connect the refrigerator to the base. Such an arrangement can make the refrigerator maintain stability to the greatest extent possible on the rear seat of the vehicle and is not easy to tilt.

[0005] In the above patent scheme, although the dual support function of the base and the bottom block can provide stable support and fixation for the vehicle electrical appliances, there are still three problems: 1. The space inside the car is small and the vehicle electrical appliances are large in size. It is not convenient to take and place the vehicle electrical appliances on the base, which is not conducive to flexible adjustment of the space layout inside the car; 2. The rigid connection between the base and the vehicle electrical appliances causes the vibration of the vehicle to be directly transmitted to the vehicle electrical appliances, which will cause certain damage to the components of the vehicle electrical appliances and reduce their service life; 3. After the connecting socket is removed, the shape is irregular and occupies a large space, which is not convenient for storage. Summary of the invention

[0006] In order to overcome the technical problems in the prior art that the connection seat for installing a vehicle oven is not easy to disassemble and assemble on the vehicle, has poor stability after installation, and occupies a large space and is inconvenient to store after disassembly, one object of the present invention is to provide a detachable bottom fixing structure for a vehicle oven, by movably setting two height-adjustable ISOFIX locks on one side of the connection seat, so that the connection seat can be stably and horizontally installed on the vehicle seat, and an abutment rod abutting against the vehicle seat back is also provided to limit the activity margin of the ISOFIX lock and increase the stability of the installation. In addition, the easy-to-disassemble design of the ISOFIX lock also makes it easy to disassemble and assemble, and occupies a small space after storage.

[0007] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a detachable bottom fixing structure for a vehicle-mounted oven, comprising a connecting seat, two locking parts arranged on one side of the connecting seat and four connecting parts arranged on the connecting seat; the connecting part can be selectively engaged with the vehicle-mounted oven; the locking part includes an ISOFIX lock with one end rotatably connected to the lower support arm of the connecting seat and the other end of the support arm rotatably connected; the rotation axis of the support arm is arranged in the horizontal direction; wherein an abutment rod is slidably connected to the connecting seat, and the abutment rod can selectively abut against the backrest of the car seat and limit the rotation of the support arm.

[0008] The ISOFIX (International StandarDS Organization FIX-child safety seat fixing system) interface is located at the bottom of the vehicle seat backrest. At the same time, based on safety and driving comfort considerations, the rear of the vehicle seat is designed to be significantly lower than the front, and the height difference between the front and rear is different for different models / series. Therefore, when the connecting seat is placed on the vehicle seat, the relative height of the ISOFIX lock and the connecting seat is changed by adjusting the rotation angle of the support arm and the connecting seat. One side of the connecting seat is supported by the ISOFIX lock and the other side is supported by the front of the vehicle seat, so that the connecting seat is horizontally and stably installed on the vehicle seat, and the car oven can be used directly on the vehicle.

[0009] Although the ISOFIX lock is easy to disassemble and assemble, there is a certain amount of movement margin between the ISOFIX and the ISOFIX interface. After the abutment rod is pressed against the car seat backrest, the above-mentioned movement margin is limited, thereby improving the stability of the connecting seat. During the driving process of the vehicle, the horizontally placed car oven can also be easily used, directly utilizing the shock absorption of the car seat, which can also achieve a certain degree of shock absorption effect.

[0010] Furthermore, the locking portion includes a second stop plate slidably connected to the connecting seat, and the second stop plate can be selectively engaged with the support arm; a linkage groove is provided on the outer wall of the second stop plate; a linkage plate slidably connected to the linkage groove is provided on the abutment rod; the linkage plate includes an inclined hypotenuse and two straight edges respectively arranged at both ends of the hypotenuse; the length direction of the straight edge is arranged along the sliding direction of the abutment rod.

[0011] Specifically, a driving shaft that is rotatably connected to the connecting seat and is transmission-connected to the abutment rod; first knobs are respectively axially slidably connected to both ends of the driving shaft, and the first knob is transmission-connected to the driving shaft; a first locking disk for limiting the rotation of the first knob is provided on the connecting seat; the first knob can selectively abut against the first locking disk.

[0012] When the abutment rod slides into the connection seat, the second stop plate does not contact the support arm, and the support arm can be rotated for height adjustment; when the abutment rod slides outward and abuts against the vehicle seat back, the second stop plate is driven to engage with the support arm, and the position of the connection seat is completely restricted. Only by turning the first knob, the rotation of the support arm can be restricted, and the abutment rod can be abutted against the vehicle seat back, thereby greatly shortening the installation steps of the connection seat and simplifying the operation steps of personnel.

[0013] Specifically, a connecting shaft is arranged between the two support arms, and the connecting shaft is coaxially arranged with the rotating axis of the support arm; the second stop plate is connected to the outer periphery of the connecting shaft along the axial sliding of the connecting shaft; two first stop plates are coaxially arranged on the connecting shaft; the second stop plate can be optionally abutted against the first stop plate.

[0014] Furthermore, four supporting legs are provided at the lower end of the vehicle-mounted oven, and positioning grooves are provided on the outer periphery of the supporting legs; the connecting part includes three limiting slides slidably connected to the connecting seat, a supporting plate longitudinally slidably connected to the connecting seat, and a second spring arranged between the supporting plate and the connecting seat; the elastic force of the second spring is used to make the supporting plate slide upward; the three limiting slides are evenly distributed along the circumferential direction, and the supporting plate is longitudinally slidably connected to the middle part of the distribution circumference of the limiting slides; the support plate is transmission-connected to the limiting slide; the limiting slide can be selectively located in the positioning groove.

[0015] The vehicle oven is placed on the connecting seat, and the four legs are respectively against the lower end of the support plate. The support plate slides downward under the gravity of the vehicle oven, thereby driving the limiting slide plate to slide into the positioning groove, limiting the movement of the vehicle oven, thereby completing the stable installation of the vehicle oven.

[0016] Specifically, the connecting part includes a primary transmission ring rotatably connected to the connecting seat and a secondary transmission ring rotatably connected to the connecting seat; the primary transmission ring is transmission-connected to the corresponding three limiting slides; the secondary transmission ring is transmission-connected to the corresponding support plates; the primary transmission ring and the secondary transmission ring are coaxially arranged; a secondary driven column is arranged on the primary transmission ring; a secondary driving groove for driving the secondary driven column to rotate is arranged on the secondary transmission ring; the secondary driven column can slide in the secondary driving groove.

[0017] During the downward movement of the support plate, the positive rotation of the secondary drive groove drives the secondary driven column to rotate, so that the limiting slide slides into the positioning groove to fix the vehicle oven; however, during the upward movement of the support plate, the reverse rotation of the secondary drive groove cannot drive the secondary driven column to rotate, but the secondary driven column slides relatively in the secondary drive groove. During the bumpy process of the vehicle, when the vehicle oven bounces upward, the vehicle oven will not separate from the connecting seat and cause it to fall, but the second spring under the support plate will buffer the vibration of the vehicle oven.

[0018] Furthermore, the connecting part includes a locking rod slidably connected to the connecting seat and a tension spring arranged between the locking rod and the secondary driven column; the side wall of the connecting seat is rotatably connected to a second knob for driving the locking rod to slide; the sliding of the locking rod is used to change the elastic force on the tension spring.

[0019] When the locking rod is in the first position, the elastic force of the tension spring is zero, and the reverse rotation of the secondary driving groove cannot drive the secondary driven column to rotate. Even if the vehicle is bumpy, the vehicle oven will not fall off the connecting seat; when the locking rod is in the second position, the elastic force of the tension spring is used to make the secondary transmission ring drive the limiting sliding column to slide in the direction away from the positioning groove, so that the vehicle oven can be removed.

[0020] Preferably, the outer wall of the support plate is provided with a longitudinal sliding column; the inner wall of the secondary transmission ring is provided with a combined sliding groove slidably connected to the longitudinal sliding column; the combined sliding groove includes a spiral groove and an axial groove arranged at the lower end of the spiral groove.

[0021] The axial groove allows the vehicle oven to have room for movement in the longitudinal direction, so that it can better cope with the bumps and vibrations of the vehicle.

[0022] Furthermore, the four locking rods are respectively located on both sides of the second knob; the outer wall of the second knob is provided with four radially arranged extension rods; the ends of the extension rods can be selectively pressed against the corresponding locking rods.

[0023] Preferably, two receiving chambers are provided below the connecting seat; the supporting arm is rotatably connected in the receiving chamber; and the receiving chamber can selectively accommodate the supporting arm and the ISOFIX lock.

[0024] Preferably, when the vehicle-mounted oven is placed on the supporting plate, the limiting slide plate does not contact the upper and lower ends of the positioning groove; the elastic force of the second spring enables the supporting plate to support the supporting foot, thereby playing a vibration isolation role.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The present invention is installed on a vehicle seat, can provide horizontal installation and vibration protection for the vehicle oven, and the vehicle oven is convenient to take and put on the connecting seat; after storage, the shape is regular and the volume is small, which is convenient for flexible adjustment of the space in the vehicle.

[0027] 2. The connecting seat is stably installed on the car seat through the ISOFIX lock. At the same time, the supporting height of the connecting seat can be adjusted to adapt to the installation position of various models and series, so that the connecting seat can be installed horizontally on the car seat, which is convenient for the use of the car oven.

[0028] 3. The abutment rod is pressed against the car seat back and limits the rotation of the support arm. It locks the height adjustment and limits the activity margin between the ISOFIX lock and the corresponding interface, which improves the firmness, simplifies the operation steps and facilitates disassembly and assembly.

[0029] 4. The car oven placed on the connecting seat is automatically locked, and the car oven can also move longitudinally within a certain range. The elastic force of the second spring supports the car oven, provides vibration buffering for the car oven, and also prevents the car oven from detaching from the connecting seat, which can better cope with vehicle bumps and protect the car oven.

[0049] Four legs 21 are provided at the lower end of the vehicle-mounted oven 2, and positioning grooves 211 are provided on the outer periphery of the legs 21; the connecting portion 5 includes a leg positioning tube 33 provided on the connecting seat 3, three limiting slide plates 51 connected to the connecting seat 3 along the radial direction of the leg positioning tube 3, a primary transmission ring 52 rotatably connected to the outer periphery of the leg positioning tube 33, a secondary transmission ring 53 rotatably connected to the outer periphery of the leg positioning tube 33, a support plate 54 connected to the leg positioning tube 33 along the axial longitudinal sliding direction, and a second spring 55 provided between the support plate 54 and the connecting seat 3.

[0050] The three limiting slide plates 51 are evenly distributed along the circumferential direction; the elastic force of the second spring 55 is used to make the support plate 54 slide upward;

[0051] A primary driven column 511 is arranged at the lower end of the limiting slide plate 51; three primary driving grooves 521 are arranged on the primary transmission ring 52 and are slidably connected to the corresponding primary driven columns 511 and are evenly distributed in the circumferential direction; the primary driving grooves 521 are arranged along the involute direction; three secondary driven columns 522 are arranged at the lower end of the primary transmission ring 52; three secondary driving grooves 531 are arranged at the upper end of the secondary transmission ring 53; the secondary driven column 522 can slide in the secondary driving grooves 531.

[0052] The outer wall of the support plate 54 is provided with three longitudinal sliding columns 541 evenly distributed in the circumferential direction; the inner wall of the support leg positioning tube 33 is provided with three guide grooves 331 arranged axially and slidably connected to the corresponding longitudinal sliding columns 541; the inner wall of the secondary transmission ring 53 is provided with a combined sliding groove slidably connected to the longitudinal sliding column 541; the combined sliding groove includes a spiral groove 532 and an axial groove 533 arranged at the lower end of the spiral groove 532.

[0053] The connecting part 5 includes a locking rod 61 slidably connected to the connecting seat 3 and a tension spring 63 arranged between the end of the locking rod 61 and the secondary driven column 522; the side wall of the connecting seat 3 is rotatably connected to a second knob 62 for driving the locking rod 61 to slide; the four locking rods 61 are respectively located on both sides of the second knob 62; a vertical plate 611 is provided at one end of the locking rod 61 close to the second knob 62; four radially arranged extension rods 621 are provided on the outer wall of the second knob 62; the end of the extension rod 621 can be optionally pressed against the corresponding vertical plate 611.

[0054] Installation process: Pull the support arm 42 and ISOFIX lock 41 out of the storage cavity 31, insert the two ISOFIX locks 41 into the corresponding ISOFIX interface, and make the connection seat 3 abut against the front of the car seat 1. Adjust the angle of the support arm 42 to make the upper end of the connection seat 3 horizontal. Press the first knob 44 inward to separate the second lock disk 442 from the first lock disk 32, compress the first spring 47, and at the same time, turn the first knob 44 forward to drive the drive shaft 46 to rotate forward, and the rotation of the drive shaft 46 drives the abutment rod 43 to slide toward the backrest of the car seat 1. The sliding of the abutment rod 43 synchronously drives the sliding of the bevel 432, and the bevel 432 drives the linkage groove 451 to make the second stop disk 45 slide toward the first stop disk 421, limiting the rotation of the support arm 42. After the first knob 44 is rotated until the contact rod 43 is pressed against the backrest of the car seat 1 , the first knob 44 is released, and the elastic force of the first spring 47 causes the second lock disk 442 to contact the first lock disk 32 again, and the drive shaft 46 cannot rotate.

[0055] The second knob 62 is turned so that the extension rod 621 cannot contact the locking rod 61, and the vehicle oven 2 is placed on the connecting seat 3, and the support leg 21 is aligned with the support plate 54, and the support plate 54 slides downward under the gravity of the vehicle oven 2. The longitudinal sliding column 541 on the support plate 54 drives the spiral groove 532 to rotate forward, thereby causing the secondary transmission ring 53 to rotate forward, and the secondary driving groove 531 drives the secondary driven column 522 to rotate, thereby causing the primary transmission ring 52 to rotate forward. The rotation of the secondary transmission ring 52 causes the primary driving groove 521 to drive the primary driven column 511 to slide, and the limiting slide plate 51 slides into the positioning groove 211 in the direction of the support leg 21, and the limiting slide plate 51 does not contact the upper and lower ends of the positioning groove 211.

[0056] During the bumping of the vehicle, the vehicle oven 2 is damped by the elastic force of the second spring 55. Even if a larger bump occurs, during the upward movement of the vehicle oven 2, that is, during the upward movement of the support plate 54 under the elastic force of the second spring 55, the secondary driving groove 531 cannot drive the secondary driven column 522 to move, so that the limiting slide plate 51 remains in the positioning groove 211 to prevent the vehicle oven 2 from falling from the connecting seat 3.

[0057] Removal process: Turn the second knob 62 90 degrees to make the extension rod 621 drive the lock rod 61 to slide, and the tension spring 63 accumulates force. In the process of moving the vehicle oven 2 upward, as the secondary transmission ring 53 rotates, the elastic force of the tension spring 63 drives the secondary driven column 522 to make the primary transmission ring 52 rotate in the opposite direction. Then, the limiting slide plate 51 is moved out of the positioning groove 211, and the vehicle oven 2 can be easily removed from the connecting seat 3.

[0058] Finally, the first knob 44 is pressed and rotated in the reverse direction to return the abutment rod 43 to its original position, and then the support arm 42 and the ISOFIX lock 41 are retracted into the storage cavity 31 .

[0059] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
