Description

Technical Field

[0001] This utility model belongs to the field of electric wheelchairs and relates to an electric wheelchair massage controller. Background Technology

[0002] Electric wheelchairs are becoming increasingly popular among people with mobility impairments and the elderly. To improve user experience and increase comfort, many manufacturers add inflatable cushions to the seat and backrest of electric wheelchairs, along with controllers equipped with air pumps to provide a massage function. While the air pumps used in existing products can quickly control the air intake and exhaust of the cushions, the vibration generated during operation remains an unresolved issue. In severe cases, this vibration can resonate with the frame, significantly impacting the user's riding experience. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an electric wheelchair massage controller.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electric wheelchair massage controller includes a housing for mounting an electric air pump. A front rubber plug and a rear rubber plug are respectively fitted onto both ends of the electric air pump, and the front rubber plug and the rear rubber plug are respectively fixedly connected inside the housing.

[0006] Furthermore, mounting pads are provided on the outer periphery of both the front and rear rubber plugs, and multiple posts are provided inside the housing to abut against the mounting pads. The mounting pads and the posts are fixed by through screws.

[0007] Furthermore, it also includes a solenoid valve and an air outlet. The air outlet is located on the outer periphery of the housing, and the solenoid valve is fixedly connected inside the housing. The solenoid valve is connected to the electric air pump and the air outlet respectively.

[0008] Furthermore, the outer side of the housing is provided with multiple support legs, and the support legs are provided with helical shock-absorbing rings.

[0009] Furthermore, the outer shell includes an upper shell and a lower shell, and mounting posts are provided inside both the upper shell and the lower shell, which are mated and connected.

[0010] In summary, the advantages of this utility model are as follows:

[0011] The controller structure of this utility model uses front and rear rubber plugs to suspend and fix the electric air pump, reducing the collision between the electric air pump and the controller. The rubber shock absorption properties effectively absorb the vibration generated by the electric air pump during operation, enhancing the overall stability of the controller and improving the user experience.

[0016] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0017] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0018] In this embodiment of the invention, all directional indicators (such as up, down, left, right, front, back, horizontal, vertical, etc.) are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indicator will also change accordingly.

[0019] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of this utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0020] This utility model provides an electric wheelchair massage controller for controlling the internal air pressure of an inflatable cushion located on the backrest of an electric wheelchair.

[0021] Reference Figure 1 The massage controller includes a housing and an electric air pump 3 and a solenoid valve 4 disposed within the housing. The massage controller is mounted on the frame of the electric wheelchair, and the massage controller is connected to the inflatable cushion via an air pipe.

[0022] Reference Figure 2 and Figure 3 The outer shell includes an upper shell 1 and a lower shell 2, which are engaged and snapped together to form an installation cavity for mounting the solenoid valve 4 and the electric air pump 3. Multiple mounting posts 21 are respectively provided in the upper shell 1 and the lower shell 2. The upper and lower mounting posts 21 are engaged synchronously when the upper shell 1 and the lower shell 2 are engaged, and are fixed by screws to fix the upper shell 1 and the lower shell 2. Rubber rings are also fitted on the mounting posts 21, so that the two ends of the rubber rings are supported by the upper and lower mounting posts 21 respectively, eliminating the movement of the connection position.

[0023] The solenoid valve 4, the electric air pump 3, and the control circuit PCB board 5 are all fixedly installed on the lower housing 2. The solenoid valve 4 is connected to the electric air pump 3. An air outlet 41 is provided on the outer periphery of the housing, which is connected to the solenoid valve 4 to allow air pressure to enter and exit the inflatable pad. An mounting plate is fitted on the outer periphery of the solenoid valve 4. The two ends of the mounting plate are fixedly connected to the lower housing 2 by screws to fix the solenoid valve 4 to the lower housing 2.

[0024] To reduce vibration during operation, a front rubber plug 31 and a rear rubber plug 32 are provided. Both the front rubber plug 31 and the rear rubber plug 32 are cylindrical structures. The front rubber plug 31 is fitted around the outer periphery of one end of the electric air pump 3, and the rear rubber plug 32 is fitted around the outer periphery of the other end of the electric air pump 3. Mounting pads are provided on the outer side of the front rubber plug 31 and the outer side of the rear rubber plug 32, and mounting holes are provided on the mounting pads. Multiple columns 22 are provided on the lower housing 2. The mounting pads abut against the top of the columns 22 and are fixed by screws inserted into the mounting holes and the columns 22, so as to fix the front rubber plug 31 and the rear rubber plug 32 to the lower housing 2 and fix the position of the electric air pump 3 by the two rubber plugs, while absorbing and reducing the vibration during operation of the electric air pump 3.

[0025] Furthermore, in this embodiment, the lower housing 2 is connected to the frame of the electric wheelchair. The bottom of the lower housing 2 is provided with multiple support legs 23, and a spiral shock absorber 231 is connected to the support legs 23.
