Description

Technical Field

[0001] This utility model relates to the field of electric coffee tables, and in particular to an electric coffee table frame. Background Technology

[0002] Traditional coffee tables, with their fixed height and single function, are no longer suitable for the diverse needs of modern life. In the living room, when people want to comfortably enjoy tea, read, or use a laptop, a fixed-height coffee table may not provide the right support angle and height, easily causing discomfort and inconvenience. In parent-child interaction scenarios, for young children, the height of a standard coffee table is too high, hindering their activities such as crafts and drawing, limiting the fun of parent-child interaction and the development of children's creativity. Furthermore, during family gatherings or meals with friends, if a large amount of food and drinks needs to be placed on the coffee table, its fixed height and limited functionality cannot be flexibly adjusted to meet the needs of multiple users and the placement of different items. From the perspective of home space utilization, a single-function coffee table cannot be adjusted in height or function according to changes in the spatial layout, resulting in inefficient and wasteful space utilization. Therefore, coffee tables urgently need improvement to suit multiple application scenarios. Utility Model Content

[0003] To improve the adaptability of coffee tables to various usage environments, this utility model provides an electric coffee table frame.

[0004] This utility model provides a technical solution that adopts the following approach:

[0005] An electric coffee table frame includes a frame body, a signal transmitter, a signal receiver, and a lifting assembly. The signal transmitter is externally mounted on the coffee table, and the signal receiver is located inside the frame body. The lifting assembly electrically lifts the top of the frame, and the signal receiver is electrically connected to the lifting assembly. The frame body includes a top frame and legs, and the legs are telescopic rods.

[0006] The user operates the signal transmitter to send an electrical signal. Upon receiving the signal, the signal receiver activates the lifting mechanism and extends / retracts the table legs, thereby controlling the raising and lowering of the top frame. This allows the coffee table to be easily adjusted to multiple different heights. The ability to adjust the coffee table to the appropriate height for different usage environments enhances its adaptability and increases its utilization rate.

[0007] Preferably, the lifting assembly includes a lead screw and a drive block disposed inside the table leg, the lead screw and the drive block forming a lead screw slider structure, the table leg includes a support part and a lifting part, the lifting part is slidably connected to the support part, the top of the lifting part is connected to the top frame, and the drive block is connected to the lifting part to drive the lifting part to move.

[0008] When the lifting assembly is activated, the lead screw rotates, which in turn drives the drive block to move along the length of the lead screw, which in turn drives the lifting part to move along the height of the support part, thereby lifting the top frame.

[0009] Preferably, the lifting assembly includes a drive motor and a reversing group. The drive motor is located on the side of the top frame near the lifting part, and the drive motor is connected to the lead screw through the reversing group.

[0010] The drive motor is located on the top frame. After the tabletop is installed on the top frame, the tabletop covers the drive motor, thus hiding the drive motor under the tabletop, which helps to improve the overall aesthetics of the coffee table.

[0011] Preferably, the reversing assembly includes a reversing box, a driving wheel, and a driven wheel. The driving wheel is connected to a drive motor. Both the driving wheel and the driven wheel are bevel gears and mesh with each other. The driven wheel is rotatably mounted on the top of the telescopic part and is sleeved and fixed to the top of the lead screw. The driving block is located at the bottom of the support part and has internal threads for threaded connection with the lead screw.

[0012] A pneumatic drive motor drives the drive wheel to rotate, which in turn drives the driven wheel to rotate. The driven wheel drives the lead screw to rotate. The drive block is restricted by the support and cannot move. Therefore, when the lead screw rotates, it slides out or into the drive block, thereby causing the telescopic part connected to the lead screw to move closer to or away from the support, thus realizing the extension and retraction of the table legs.

[0013] Preferably, both the telescopic part and the support part are square cylindrical, the telescopic part is inserted into the support part, and the outer peripheral wall of the telescopic part is in contact with the inner peripheral wall of the support part.

[0014] The telescopic part and the support part restrict each other, making it difficult for the telescopic part to rotate, and allowing the telescopic part to slide stably within the support part.

[0015] Preferably, the axis of the drive wheel is horizontally arranged, the center of the drive wheel has a drive groove, the drive groove is a polygonal groove, and the output end of the drive motor is connected to a polygonal shaft corresponding to the polygonal groove.

[0016] By inserting the polygonal shaft into the polygonal slot, the drive wheel can be driven to rotate. When the polygonal shaft of the motor or the drive wheel wears out, the damaged parts can be removed and replaced, which helps to reduce the cost of replacement and maintenance.

[0017] Preferably, the polygonal groove is a hexagonal groove, and the polygonal shaft is a hexagonal shaft.

[0018] Preferably, the reversing box has a connecting hole on one side along the length of the polygonal shaft for the polygonal shaft to pass through, a support column is connected to the side of the drive wheel away from the polygonal shaft, a bearing is connected to the end of the support column away from the drive wheel, and a limiting groove for installing the bearing is recessed on the inner side wall of the reversing box away from the connecting hole.

[0019] The combination of bearings and support columns can support and stabilize the drive wheel. While stabilizing the drive wheel, the bearings and support columns can also prevent the drive wheel from separating from the polygonal shaft, making the overall structure more compact.

[0020] Preferably, the top frame is also connected to two sides of an expansion frame, which is set to correspond to the shape of the coffee table's tabletop and is used to install the tabletop.

[0021] In summary, this utility model has the following beneficial technical effects:

[0022] The user operates the signal transmitter to send an electrical signal. Upon receiving the signal, the signal receiver activates the lifting mechanism and extends / retracts the table legs, thereby controlling the raising and lowering of the top frame. This allows the coffee table to be easily adjusted to multiple different heights. The ability to adjust the coffee table to the appropriate height for different usage environments enhances its adaptability and increases its utilization rate. Attached Figure Description

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0027] This utility model discloses an electric coffee table frame.

[0028] Reference Figure 1An electric coffee table frame includes a frame body 1, a signal transmitter, a signal receiver, and a lifting component. The signal transmitter is externally placed on the coffee table, and the signal receiver is located inside the frame body 1. The lifting component electrically lifts the top of the frame. The signal receiver is electrically connected to the lifting component. The frame body 1 includes a top frame 2 and table legs 3, and the table legs 3 are telescopic rods.

[0029] The user operates the signal transmitter to send an electrical signal. Upon receiving the signal, the signal receiver activates the lifting assembly and extends / retracts the table legs 3, thereby controlling the raising and lowering of the top frame 2. This allows the coffee table to be easily adjusted to multiple different heights. The ability to adjust the coffee table to the appropriate height in different usage environments enhances its adaptability and increases its utilization rate.

[0030] Reference Figure 1 as well as Figure 2 In this embodiment, the lifting component includes a lead screw 4 and a drive block disposed in the table leg 3. The lead screw 4 and the drive block constitute a lead screw 4 slider structure. The table leg 3 includes a support part 5 and a lifting part 6. The lifting part 6 is slidably connected to the support part 5. The top of the lifting part 6 is connected to the top frame 2. The drive block is connected to the lifting part 6 to drive the lifting part 6 to move.

[0031] The lifting assembly is activated, causing the lead screw 4 to rotate, which in turn drives the drive block to move along the length of the lead screw 4, and drives the lifting part 6 to move along the height of the support part 5, thereby driving the top frame 2 to rise and fall.

[0032] Reference Figure 1 as well as Figure 2 In this embodiment, the lifting assembly includes a drive motor 7 and a reversing group. The drive motor 7 is located on the side of the top frame 2 near the lifting part 6, and the drive motor 7 is connected to the lead screw 4 through the reversing group.

[0033] The drive motor 7 is electrically connected to the signal receiver. The drive motor 7 is installed on the top frame 2. After the tabletop is installed on the top frame 2, the tabletop covers the drive motor 7, thus hiding the drive motor 7 under the tabletop, which helps to improve the overall aesthetics of the coffee table.

[0034] Reference Figure 1 as well as Figure 2 In this embodiment, the reversing group includes a reversing box 8, a driving wheel 9 and a driven wheel 10. The driving wheel 9 is connected to the drive motor 7. Both the driving wheel 9 and the driven wheel 10 are bevel gears and they mesh with each other. The driven wheel 10 is rotatably located on the top of the telescopic part. The driven wheel 10 is sleeved and fixed on the top of the lead screw 4. The drive block is located at the bottom of the support part 5. The drive block has internal threads so as to be threadedly connected to the lead screw 4.

[0035] The pneumatic drive motor 7 drives the drive wheel 9 to rotate, which in turn drives the driven wheel 10 to rotate. The driven wheel 10 drives the lead screw 4 to rotate. The drive block is restricted by the support part 5 and is difficult to move. Therefore, when the lead screw 4 rotates, it causes the lead screw 4 to slide out or slide into the drive block, thereby causing the telescopic part connected to the lead screw 4 to move closer to or away from the support part 5, thus realizing the extension and retraction of the table leg 3.

[0036] Reference Figure 1 as well as Figure 2 In this embodiment, both the telescopic part and the support part 5 are square cylindrical. The telescopic part is inserted into the support part 5, and the outer peripheral wall of the telescopic part is in contact with the inner peripheral wall of the support part 5.

[0037] The telescopic part and the support part 5 restrict each other, making it difficult for the telescopic part to rotate and allowing the telescopic part to slide stably within the support part 5.

[0038] Reference Figure 1 as well as Figure 2 In this embodiment, the axis of the drive wheel 9 is horizontally set, and a drive groove 11 is opened at the center of the drive wheel 9. The drive groove 11 is a polygonal groove, and the output end of the drive motor 7 is connected to a polygonal shaft 12 corresponding to the polygonal groove.

[0039] By inserting the polygonal shaft into the polygonal slot, the drive wheel 9 can be driven to rotate. When the polygonal shaft 12 of the motor or the drive wheel 9 is worn, the damaged parts can be removed and replaced, which helps to reduce the cost of replacement and maintenance.

[0040] Reference Figure 1 as well as Figure 2 In this embodiment, the drive groove 11 is a hexagonal groove, and the polygonal shaft 12 is a hexagonal shaft.

[0041] A commutator is also connected between the polygonal shaft 12 and the drive motor 7, and the drive shaft of the drive motor 7 is connected to the drive wheel 9 of the commutator. The arrangement of the two commutator groups can transmit the power of the drive motor 7 to the polygonal shaft 12 through the commutator groups, which helps to protect the polygonal shaft 12.

[0042] Reference Figure 1 as well as Figure 2 In this embodiment, the reversing box 8 has a connecting hole 13 on one side along the length of the polygonal shaft 12 for the polygonal shaft 12 to pass through. The side of the drive wheel 9 away from the polygonal shaft 12 is connected to a support column 14. The end of the support column 14 away from the drive wheel 9 is connected to a bearing 15. The inner sidewall of the reversing box 8 away from the connecting hole 13 has a limiting groove 16 for installing the bearing 15.

[0043] The cooperation between bearing 15 and support column 14 can support and stabilize drive wheel 9. While stabilizing drive wheel 9, bearing 15 and support column 14 can also prevent drive wheel 9 from separating from polygonal shaft 12, making the overall structure more compact.

[0044] Reference Figure 1 as well as Figure 2 In this embodiment, the top frame 2 is also connected to the two sides of the expansion frame 17. The expansion frame 17 is set according to the shape of the coffee table tabletop and is used to install the tabletop.

[0045] The extended frame 17 can enhance the stability of the table frame body 1 in supporting the tabletop, and apply the weight of the tabletop to the table frame body 1 more evenly, which is beneficial to protecting the tabletop and the table frame body 1.

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
