[0062] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0063] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0064] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0065] The present application provides an ultrasound device that can detect a detection object using ultrasound signals and form a corresponding image to help doctors diagnose and treat. The ultrasound device can be a desktop ultrasound device or a portable ultrasound device. The desktop ultrasound device is usually large in size and is generally placed in a fixed position for use and is not frequently moved, while the portable ultrasound device is usually smaller in size and is easy to carry, such as but not limited to a notebook ultrasound device.

[0066] For some examples, please refer to Figure 1 The ultrasound device includes a base 100, a control key assembly 200, and a control unit (not shown in the figure). Of course, in other embodiments, the ultrasound device may also have other components according to other requirements. For example, in some embodiments, it may also have a display device for displaying ultrasound signals, an ultrasound probe for transmitting and receiving ultrasound signals, and a probe docking module for docking the ultrasound probe.

[0067] The control key assembly 200 is supported on the base 100. In some embodiments of the portable ultrasound device, the base 100 can be used as a supporting structure of the entire ultrasound device, and the control unit can also be arranged in the base 100. In some embodiments of the desktop ultrasound device, the base 100 can be the base 100 of the control panel, and the control panel can be additionally installed on the ultrasound host, and the control unit can be installed in the ultrasound host.

[0068] The control key assembly 200 is used by the operator to input commands related to ultrasonic testing operations. The control key assembly 200 includes a control key circuit board 210 and a flexible outer cover 220 fixed to each other. The control key circuit board 210 is electrically connected to the control unit to transmit the control command input by the operator to the control unit. Figure 1 In some embodiments, the control key circuit board 210 has a plurality of control switches 211. When these control switches 211 are triggered, they can input signals representing corresponding information to the control unit. For example, they can be pot pieces commonly used for push-type control keys, inductive control switches commonly used for inductive control keys, etc.

[0069] The flexible outer cover 220 is used by the operator to input instructions related to the ultrasonic detection operation. Specifically, the flexible outer cover 220 includes a plurality of control keys 221 for the operator to input trigger signals, and the control keys 221 are opposite to the corresponding control switches 211 so that the operator can trigger the corresponding control switches 211 through the control keys 221.

[0070] The flexible outer cover 220 forms an integrated waterproof structure, for example, it can be an integrally formed structure, or it can be a whole formed by sealing and assembling a plurality of separately manufactured sub-units. The flexible outer cover 220 covers the control switch 211 of the control key circuit board 210, thereby forming a waterproof layer on the control switch 211 of the control key circuit board 210. This integrated structure has a better waterproof effect. The flexible outer cover 220 includes a plurality of control keys 221 for the operator to input a trigger signal, and the control keys 221 are opposite to the corresponding control switches 211 so that the operator can trigger the corresponding control switches 211 through the control keys 221. The operator can control the display device to display content related to the ultrasonic detection operation through these control keys 221, and can also adjust various parameters in the ultrasonic detection operation, etc. The specific control content can refer to the existing various ultrasonic equipment.

[0071] In some embodiments, the outer surface of the control key 221 is provided with a mark indicating the function of the control key 221, and the mark is used for the operator to identify different control keys 221. The mark can be, but is not limited to, text, pattern or other forms of marks.

[0072] In the above embodiment, the flexible outer cover 220 replaces a single button in the existing ultrasonic device for the operator to input instructions. Since the flexible outer cover 220 is an integrated waterproof structure, there is no need to set an active gap, which can achieve a better waterproof effect. Moreover, in the control key assembly 200, the operator can directly trigger the control switch 211 on the control key circuit board 210 through the control key 221 of the flexible outer cover 220, without setting other button structures, which can further reduce the thickness of the entire control key assembly 200.

[0073] The flexible outer cover 220 is made of a flexible material, such as silicone or other similar materials. Figure 1 In the illustrated embodiment, the flexible outer cover 220 is an integrally formed silicone outer cover. Of course, in other embodiments, the silicone outer cover may also be made into a plurality of sub-units and sealed and fixed into an integral structure, for example, by ultrasonic welding to form an integral structure.

[0074] The control keys 221 on the flexible outer cover 220 are used to directly receive the operator's instructions. According to the control requirements, various types of control keys 221 can be formed on the flexible outer cover 220, and each control key 221 can have a corresponding function. The specific function type and layout of the control keys 221 can refer to the key structure of various existing ultrasonic devices. Among them, the operator can trigger these control keys 221 by, but not limited to, pressing, touching or any other existing triggering methods.

[0075] Please refer to Figure 1 In some embodiments, at least one control key 221 is a push-type control key 222. In this case, the control switch 212 corresponding to the push-type control key 222 may be a pot piece or other structure that can be triggered by the push-type control key 222, that is, the operator triggers the control key 221 by pressing. Figure 2 In some embodiments, the push-type control key 222 includes a key body 2221. The push-type control key 222 may also include an elastic reset member. The elastic reset member forms an elastic support for the key body 2221, so that the key body 2221 can move toward the corresponding control switch 211 under the pressure of the operator and trigger the control switch 211. After the pressing force of the operator disappears, the elastic reset member can drive the key body 2221 to reset.

[0076] The elastic reset member and the key body 2221 may be an integral structure, or the elastic reset member may be an independent structure relative to the key body 2221, and its elastic force may act directly or indirectly on the key body 2221 to provide a reset force to the key body 2221 to reset it.

[0077] Please refer to Figure 2In some embodiments, the elastic reset member is an elastic arm arranged around the key body 2221, which can support the key body 2221 and provide a reset force for the key body 2221. The elastic arm is sealed with the key body 2221, and the two can be an integrally formed structure or a sealed fixed structure. The elastic arm is arranged around the key body 2221, so as to form a waterproof structure around the key body 2221, which plays a waterproof and dustproof role.

[0078] Please refer to Figure 1 and 2 In some embodiments, the flexible outer cover 220 further includes a base 224, which is a mounting and supporting base for each control key 221. The elastic reset member is an elastic arm 2222. The key body 2221 is connected to the base 224 through the elastic arm 2222. The elastic arm 2222 and the base 224 are also sealed and connected, and the two can be either an integrally formed structure or a sealed fixed structure. Figure 1 and 2 In the illustrated embodiment, the elastic arm 2222, the base 224 and the key body 2221 are an integrally formed structure. In addition, in other embodiments, the elastic arm 2222 and the base 224 can also be fixedly connected by ultrasonic welding or other methods.

[0079] For further information, please refer to Figure 2 In some embodiments, the thickness a1 of the elastic arm 2222 is smaller than the thickness a2 of the key body 2221. When the thickness a1 of the elastic arm 2222 is smaller than the thickness a2 of the key body 2221, the elastic arm 2222 is more easily deformed than the key body 2221, so that the key body 2221 can be more easily moved toward the corresponding control switch 211 under the pressure of the operator, thereby obtaining a lighter and smoother pressing feel.

[0080] More specifically, in some embodiments, the ratio A of the thickness a1 of the elastic arm 2222 to the thickness a2 of the key body 2221 is: 0.02≤A≤0.22. Under this thickness ratio range, the key body 2221 can be more easily moved toward the corresponding control switch 211 under the pressure of the operator to obtain a lighter and smoother pressing feel, and the elastic arm 2222 can also have sufficient resetting elastic force to drive the key body 2221 to return to its original position.

[0081] Alternatively, in some embodiments, the thickness a1 of the elastic arm 2222 is 0.12 mm ≤ a1 ≤ 0.40 mm, and the thickness a2 of the key body 2221 is a2 ≥ 2.1 mm. Within this value range, the key body 2221 can be more easily moved toward the corresponding control switch 211 under the pressure of the operator to obtain a lighter and smoother pressing feel, and the elastic arm 2222 can also have sufficient resetting elastic force to drive the key body 2221 to return to its original position.

[0082] Of course, in some other embodiments, the thickness a1 of the elastic arm 2222 may also be greater than or equal to the thickness a2 of the key body 2221 , so that the resetting elastic force of the elastic arm 2222 is greater and the key body 2221 can be reset more quickly.

[0083] Further, in some embodiments, please refer to Figure 2 In order to make it easier for the operator to press, at least a portion of the button body 2221 protrudes from the base 224.

[0084] In order to better support the button body 2221 and provide a restoring elastic force, please refer to Figure 1 and 2 In some embodiments, the elastic arm 2222 has a cylindrical structure with one end being large and the other end being small. The structure is similar to a truncated cone, but the radial cross-section of the cylindrical structure is not limited to a circle, and may also be a square or other shapes. The small end of the cylindrical structure surrounds and is connected to the key body 2221, and the large end of the cylindrical structure is connected to the base 224. That is, Figure 2 As shown, in the cross-sectional view along the thickness a2 direction of the key body 2221, the cross-section of the elastic arm 2222 forms a shape that is inclined from top to bottom. Of course, in other embodiments, the elastic arm 2222 may also be in other shapes, for example, in the cross-sectional view along the thickness a2 direction of the key body 2221, the cross-section of the elastic arm 2222 may also be in a wavy shape, a folded shape, or a plane shape perpendicular to the thickness a2 direction of the key body 2221.

[0085] For some examples, please refer to Figure 2 The button body 2221 is provided with a conductive circuit 2221a. When the button body 2221 moves to contact the corresponding control switch 211, the conductive circuit 2221a is connected to the control switch 211. For example, the conductive circuit 2221a contacts the gold finger in the control switch 211 to trigger the control switch 211.

[0086] In some embodiments, the conductive circuit 2221a is formed by conductive particles embedded in the key body 2221. These conductive particles are mixed in the key body 2221 to form the conductive circuit 2221a. The conductive circuit 2221a has a contact exposed on the key body 2221, so that it can be connected to the control switch 211 when the key body 2221 moves to contact the corresponding control switch 211. In addition, in other embodiments, the conductive particles can be used but not limited to conductive carbon particles.

[0087] Of course, in other embodiments, the button body 2221 can also trigger the control switch 211 in other ways. For example, the button body 2221 does not have a conductive circuit 2221 a , but the control switch 211 is triggered by pressing the control switch 211 .

[0088] In addition, in addition to the above-mentioned push-type control key 222, in other embodiments, please refer to Figure 1 At least one control key 221 in the flexible outer cover 220 is an inductive control key 223, and the control switch 211 corresponding to the inductive control key 223 is an inductive control switch 213, and the inductive control key 223 covers the inductive control switch 213. The operator can control the inductive control switch 213 by touching the inductive control key 223.

[0089] In some embodiments, the inductive control switch 213 is a mutual capacitance inductive control switch or other types of reactive control switches 211 that can be triggered without direct contact.

[0090] To improve the touch feel, please refer to Figure 3 In some embodiments, the inductive control key 223 has a recess 2231 on one side facing away from the corresponding inductive control switch 213 , and a touch film 2232 is disposed in the recess 2231 . The touch film 2232 is used to provide a touch feel different from that of the flexible outer cover 220 .

[0102] Further, in order to increase the stability and waterproofness of the control key assembly 200 on the base 100, please refer to Figure 4 In some embodiments, the control panel further comprises a base 100. The base 100 has an installation cavity 110, and the control key assembly 200 is fixedly installed in the installation cavity 110, and a waterproof seal is formed around the control key assembly 200 and the base 100. Such a waterproof seal can be achieved by providing a special seal, or by a docking structure between the control key assembly 200 and the base 100.

[0103] Please refer to Figure 4 In some embodiments, the flexible outer cover 220 is buckled on the control key circuit board 210, and the flexible outer cover 220 has a side wall body 228 buckled on the side of the control key circuit board 210. The side wall body 228 and the cavity wall 111 of the installation cavity 110 are tightly fitted and sealed. Since the side wall body 228 of the flexible outer cover 220 has a certain degree of deformability, it can form an interference fit with the base 100, thereby achieving a waterproof effect.

[0104] Of course, in other embodiments, a sealing member is provided between the control key assembly 200 and the cavity wall of the installation cavity 110 to achieve waterproof sealing. The sealing member can be a sealing ring or a sealing glue.

[0105] The control key assembly 200 shown in the present application above uses an integrated flexible outer cover 220 to simultaneously realize the ultrasonic functions of key pressing conduction, TGC, and encoder. While streamlining the thickness of the entire machine, it can achieve the seamless appearance requirements of the entire control key assembly 200 area, and meet the requirements of waterproof and dustproof control panel. The control key assembly shown in the present application can be integrated and installed on the base of an ultrasonic portable notebook, or it can be used on a desktop ultrasonic device and arranged on a support portion above the host.
