[0001] The utility model relates to the field of mechanical manufacturing, in particular to a touch-type gear shifter used in a car cab. Background Art

[0002] Currently, touch-type shifters are increasingly used in the field of automobile shifting to issue shifting instructions.

[0003] Existing touch-sensitive shifters generally use a capacitive film, a resistive film, or a pressure-sensitive element disposed in a touch screen panel to sense a user's pressing position.

[0004] However, this sensing method has problems such as unreliable sensing results or complex recognition algorithms for various vehicle motion conditions, and it is necessary to improve it through a new touch-type shifter. Utility Model Content

[0005] Based on the above technical problems in the prior art, the utility model aims to provide a touch-type shifter. According to the touch-type shifter of the utility model, the sensing of the user's touch and pressure is more accurate and the identification is simpler, which is conducive to meeting more sports conditions of the car.

[0006] To this end, the utility model provides a touch-type shifter, comprising:

[0007] shifter base;

[0008] A touch panel, the touch panel being mounted on the shifter base and comprising a touch area for a user to touch and press;

[0009] two pressure sensors, each used to sense pressure values ​​at two different pressure sensing points on the touch panel; and

[0010] A capacitive film is installed on the touch panel, and the capacitive film can reflect the change of capacitance when the user's fingertip touches different positions.

[0011] The above-mentioned touch-type shifter according to the utility model has a simple structure, and only requires a combination of two pressure sensors and a capacitive film to give the linear position in the direction of the connection between the two pressure sensors. Therefore, the mechanical structure and the coordination relationship between the components are simple, the performance of the entire shifter subsystem itself is reliable, and it can be modified using components commonly used in the prior art to adapt to the market and actual production and processing needs.

[0012] According to a preferred embodiment of the touch-type shifter of the present invention, the touch area is located between the two pressure sensing points.

[0013] The touch area arranged in this way can better utilize the difference in pressure values ​​between two pressure sensing points to assist in determining the touch pressing position. Such an arrangement is also an example of the structural structure of the pressure sensing points and the pressure transmission part coordinated therewith, which will be described later.

[0014] According to a preferred embodiment of the touch-type shifter of the present invention, the touch area includes three spaced-apart sub-touch areas distributed along a direction of a line connecting two of the pressure sensing points and spaced apart from each other.

[0015] The sub-touch areas distributed in this way are further helpful in assisting the determination of the touch pressing position by utilizing the difference in the pressure values ​​between the two pressure sensing points. Such an arrangement also conforms to the usual operating habits of drivers and the general requirements of motor vehicles for gear settings.

[0016] According to a preferred embodiment of the touch-type shifter of the present invention, the sub-touch areas respectively indicate the D gear, the P gear and the R gear.

[0017] This is a preferred embodiment of the touch-type shifter according to the utility model, and the sequential arrangement of the forward gear, the parking gear and the reverse gear is a gear distribution method commonly used in the art.

[0019] Such relative arrangement of the pressure sensor and the pressure sensing point and force transmission through the pressure transmission part are conducive to ensuring the accuracy of pressure transmission and are particularly suitable for use in road conditions with severe vibrations of a moving motor vehicle.

[0020] According to a preferred embodiment of the touch-type shifter of the present invention, the pressure transmission portion is integrated with the touch panel.

[0021] This integrated arrangement can further improve the movement consistency between the pressure transmission part and the touch panel, specifically the touch points on the touch panel, so as to further facilitate the force transmission through the pressure transmission part and ensure the accuracy of pressure transmission. In particular, when "zero contact" with the pressure sensor is required, this arrangement can facilitate the smooth assembly process.

[0022] According to a preferred embodiment of the touch-type shifter of the present utility model, the shifter base includes a mounting substrate and a mounting bracket fixed on the mounting substrate, the printed circuit board is mounted on the mounting bracket, and the touch panel is mounted on the mounting bracket.

[0023] By dividing the shifter base into a detachable mounting base plate and a mounting bracket, it is possible to facilitate the installation and removal of the components contained in the shifter base, thereby facilitating not only the assembly production process but also the operation in the subsequent maintenance stage.

[0024] According to a preferred embodiment of the touch-type gear shifter of the present invention, the capacitive film is attached to the touch area on the touch panel.

[0025] The above-mentioned setting position of the capacitive film is conducive to redundancy and calibration with the sensing result of the pressure sensor, thereby facilitating the reliability and safety of the sensing result.

[0026] In addition, the utility model also relates to a cab, comprising the touch-type shifter according to the above content.

[0051] Reference will now be made in detail to embodiments of the present invention, examples of which are shown in the accompanying drawings and described below.

[0052] Although the utility model will be described in conjunction with exemplary embodiments, it should be appreciated that this specification is not intended to limit the utility model to those exemplified embodiments. On the contrary, the utility model is intended to cover not only these exemplary embodiments, but also various alternative forms, modified forms, equivalent forms and other embodiments that can be included in the spirit and scope of the utility model.

[0053] In order to facilitate explanation and accurately define the technical solutions of the present invention, the terms “upper”, “lower”, “inner” and “outer” are used to describe features of the exemplary embodiments shown in the drawings with reference to their positions.

[0054] See also Figure 1 , shows a cross-sectional schematic diagram of a touch-type shifter 100. Figure 1 The touch type shifter 100 shown in FIG. 1 includes a shifter base 110, a touch panel 120, two pressure sensors 130, and a capacitive film 140. The touch type shifter 100 of the present invention can be used in a vehicle and a cab of the vehicle.

[0055] Although not required, a preferred structure of the shifter base 110 may include a mounting base plate 111 and a mounting bracket 112 attached to the mounting base plate 111. The mounting bracket 112 may be placed above the mounting base plate 111 by a structure that cooperates with the mounting base plate 111 and fixed by threaded fasteners at recessed portions of the two that are recessed toward each other, such as Figure 1 However, it should be made clear that the structure and specific shape of the shifter base 110 are not limited thereto, but may also include, for example, an integrally formed shifter base 110, or, for example, include a mounting base 111 and a mounting bracket 112 having a different form from that shown in the figure. For example, the two may be fixed to each other by a shape-fitting relationship without the aid of threaded fasteners, and for example, the quantitative relationship between the two may be that a plurality of mounting brackets 112 share one mounting base 111 or vice versa.

[0056] In the above preferred case, the circuit board 113 and the touch panel 120 may be mounted on the mounting bracket 112 .

[0057] Of course, the installation method of the circuit board 113 is not limited thereto. For example, the circuit board 113 may also be installed on the installation substrate 111 .

[0058] Furthermore, it should be pointed out that although Figure 1 The preferred installation method of the circuit board 113 is shown in detail in FIG. 1 , but the circuit board 113 can be split into multiple pieces (e.g. Figure 1 The circuit board 113 can also be a whole piece, and can also be fixed to the fixed part of the touch-type shifter 100 by other various common fastening methods. No more details are given here.

[0059] Furthermore, in addition to the illustrated positions of the above-mentioned single-point or multi-point bolt fixing, that is, the left and right circuit boards 113 are respectively fixed at the positions where bolt fasteners are installed near the left edge and near the right edge, and the middle circuit board 113 is fixed at the positions where bolt fasteners are installed on the left and right, different installation and fixing positions can also be selected according to actual needs.

[0060] Finally, regarding the installation method of the circuit board 113, it should be pointed out that even in the case of using bolts for threaded connection, the specific form and size of the bolts shown in the figure are only for reference. Technical personnel in this field can also install the necessary structures for bolt or screw connection such as smooth holes for screws and screw holes for screws in different positions according to actual needs.

[0061] The touch panel 120 is mounted on the shifter base 110 and includes a touch area 121 for the user to touch and press. Pressure sensing points 122 are arranged on the touch panel 120 (see FIG. 1 ). Figure 2 ).

[0062] It should be pointed out that if Figure 1 The protruding flanges on the left and right sides of the touch panel 120 shown in FIG. 1 and / or Figure 2 The cross-sectional shape of the touch panel 120 shown in the figure, which is roughly uniform in the middle and has arc transitions and tapers at both ends, is only for illustration, and is for the purpose of better maintaining the position of the touch panel 120 and making the touch-type shifter 100 of the present invention more convenient to match and install in the vehicle cab as a whole. Those skilled in the art may also design touch panels 120 of other different shapes according to actual needs.

[0063] The two pressure sensors 130 are respectively used to sense the pressure values ​​at two different pressure sensing points 122 on the touch panel 120. The utility model aims to use these two separate pressure sensors 130 to accurately sense the touch position. Under the premise of using two fixed pressure sensors 130, those skilled in the art can, for example, obtain the specific area of ​​the touch by comparing the difference in the sensing values ​​between the two pressure sensors based on the deformation characteristics of the material. Since how to specifically obtain the corresponding sensing area is not the focus of the improvement of the utility model, it is only briefly described as an example here. Those skilled in the art can also choose other common methods according to actual needs, which will not be repeated here.

[0064] It should also be pointed out that Figure 2 The positions of the pressure sensing points 122 shown in the figure are for illustration only, and those skilled in the art may distribute the two pressure sensing points 122 at different intervals on the touch panel 120 according to actual requirements.

[0065] According to a preferred embodiment, the pressure sensor 130 can be fixedly mounted on the circuit board 113 of the shifter base 110. In this case, the touch panel 120 includes a pressure sensor extending from the pressure sensing point 122 and extending at the Figure 1 In the figure, the pressure transmitting portion 123 extends downward from the area of ​​the touch panel 120 located above to the corresponding pressure sensor 130, so that the pressure transmitting portion 123 moves with the movement of the pressure sensing point 122.

[0066] More preferably, the pressure transmission part 123 can be integrated with the touch panel 120. For example, the pressure transmission part 123 can be integrated with the touch panel 120 during the actual assembly process by a photosensitive cementing agent, so as to maintain zero contact with the pressure sensor 130.

[0067] Obviously, in addition to the above preferred arrangement, the specific structure and arrangement of the pressure sensor 130 and the pressure transmission part 123 are not limited thereto. For example, but not limited to, the pressure sensor 130 can be detachably mounted on the shifter base 110, or the pressure sensor 130 can also be mounted on other parts that do not move with the deformation of the touch panel 120, which will not be described in detail here.

[0068] The capacitive film 140 is installed on the touch panel 120, and the capacitive film 140 can reflect the capacitance change when the user touches and presses different positions of the touch area 121. Figure 1 In the preferred embodiment shown in , the capacitive film 140 may be attached to the touch panel 120 on the reverse surface at the touch area 121 .

[0069] exist Figure 2 In the preferred embodiment shown in , the touch area 121 framed by the red frame can be preferably arranged between the two pressure sensing points 122 on the touch panel 120. However, this preferred embodiment is not necessary, because those skilled in the art can also deduce the pressure changes at the two pressure sensing points 122 caused by the touch pressing outside the two pressure sensing points 122 according to the deformation characteristics of the material. In some cases, part of the touch area 121 or a part of the entire touch area 121 can also be located outside the two pressure sensing points 122.

[0070] Furthermore, Figure 2 As shown in FIG. 1 , the touch area 121 may include three sub-touch areas 121A, 121B, and 121C (eg, Figure 2 The blue box in the figure shows the schematic outline).

[0071] In this case, the three sub-touch areas 121A, 121B, and 121C can be used to touch and select the D gear, the P gear, and the R gear, respectively. Figure 2 As shown in , those skilled in the art may further consider using, for example, an LED light array or other indication methods to visually indicate the gear position corresponding to each area on the corresponding area.

[0072] However, it should be pointed out that the above division of the touch area 121 is only an example. Those skilled in the art can also divide the touch area 121 into more or fewer touch sub-areas according to actual needs, and the shapes, sizes and distributions of the touch sub-areas within the touch area 121 are not limited thereto. Those skilled in the art can carry out personalized and customized designs according to actual needs, which will not be elaborated here.

[0073] Preferred embodiments of the present invention have been described in detail above, but it should be understood that aspects of the embodiments can be modified, if necessary, to employ aspects, features and concepts of the various patents, applications and publications to provide further embodiments.

[0074] These and other changes can be made to the embodiments in light of the above detailed description.In general, in the claims, the terms used should not be considered limited to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which these claims are entitled.
