FIG. 1 illustrates a perspective view of the alarming system for an wiper according to an embodiment of the invention, and FIG. 2 illustrates an exploded view of the alarming system according to an embodiment of the invention. As shown in FIGS. 1 and 2, an alarming system for a wiper comprises a first connecting member 1 and a second connecting member 2. In this embodiment, the first connecting member 1 is connected to the wiper arm 3, and the second connecting member 2 is connected to the wiper blade 4. The engagement between the wiper blade 4 and the wiper arm 3 is achieved by the engagement of the wiper blade adapter 41 and the wiper arm adapter 31. In this embodiment, the wiper blade adapter 41 is snap-fitted into the wiper arm adapter 31 by pushing the wiper blade adapter 41 into the wiper arm adapter 31 along a long-axis direction of the wiper blade adapter 41, and thus the engagement of the wiper blade 4 with the wiper arm 3 is achieved.

FIGS. 3, 4 a and 4b respectively show enlarged views of the alarming system according to an embodiment of the invention. In the figures, for clarity, only the wiper blade adapter 41 and the wiper arm adapter 31 are shown. FIG. 3 shows the case where the first connecting member 1 is not engaged with the second connecting member 2, and FIGS. 4a and 4b shows the case where the first connecting member 1 is engaged with the second connecting member 2. Specifically, as shown in FIGS. 3, 4a and 4b, in this embodiment, the first connection member 1 is located in the housing of the wiper arm adapter 31, and the second connection member 2 is located in the housing of the wiper blade adapter 41.

FIG. 5 illustrates an exploded view of the first connecting member 1 according to an embodiment of the invention, and FIG. 6 illustrates a view of the first connecting member and wiper arm adapter 31 according to an embodiment of the invention.

As shown in FIG. 5, the first connecting member 1 comprises a first body 11 and a first number of first contacts 12 which are insulated to each other and disposed at the first body 11. The first contacts 12 are made of electrically conductive material, and the first body 11 is made of insulated material. In this embodiment, the first number equals two, and the first number may also be selected as greater than two as required. For example, when the first number is greater than two, the additional first contacts 12 may be used to be charged with electricity to heat liquid, such as cleaning fluid, in the wiper.

As shown in FIG. 5, in this embodiment, two rod-shaped projections 111 are disposed on one side face of the first body 11, and the first contact elements 12 are respectively disposed on the outer surfaces of the rod-shaped projections 111. Specifically, two cylindrical rod-shaped projections 111 project from one side face of the first body 11, and two first contacts 12 are nested on the ends of the two rod-shaped projections 111 respectively and are made of electrically conductive material, such as copper. Specifically, the general shape of the first body 11 is adapted to be fixed in the housing of the wiper arm adapter 31. Alternatively, the first body 11 and the rod-shaped projections 111 may be of other shapes, respectively. Alternatively, the first contacts 12 may be provided at other positions of the outer wall of the rod-shaped projection 111, such as fully or partially cladding on the outer peripheral wall, or only disposed on the end surface. For example, in other embodiments, the first contacts 12 may be rod-shaped, which is connected to one side face of the first body 11. In the case where the first contacts 12 are rod-shaped, the first body 11 may not have the rod-shaped projections 111.

As shown in FIG. 5, the first connecting member 1 may further include a sealing gasket 13 disposed around the rod-shaped projection 111, and the sealing gasket 13 may be made of rubber material. When the first connecting member 1 and the second connecting member 2 are connected, the sealing gasket 13 is located between the first body 11 of the first connecting member 1 and the second body 21 of the second connection member 2 (the second body will be described in detail below) and seals therebetween.

As shown in FIG. 6, in this embodiment, the first connecting member 1 further includes two parallel positioning walls 112 protruding from one side face of the first body 11, and a buckle 113 at the other side face of the first body 11. Correspondingly, the wiper arm adapter 31 is provided with a positioning projection 311 and a snap groove 312. In this way, the first connecting member 1 can be snap-fitted into the housing of the wiper arm adapter 31. When mounting the first connecting member 1 onto the wiper arm adapter 31, firstly the orientation of the first connecting member 1 is adjusted, and then the positioning wall 112 receives the positioning projection 311 and finally the first connecting member 1 is pressed into the housing of the wiper arm adapter 31 in the direction of the arrow shown in FIG. 6, such that the buckle 113 is received into the snap groove 312. In other embodiments, the first connecting member 1 may also be fixed in the housing of the wiper arm adapter 31 in other manners, or the first connecting member may be connected to the wiper arm 3 other than the wiper arm adapter 31 in other ways. This other way is, for example, connecting by fasteners, adhering, welding, or the like. In addition, the first connecting member 1 may be connected to the wiper arm adapter 31 or other part of the wiper arm 3 through a flexible connection member such as a strap or a cord.

FIGS. 7a, 7b illustrates an exploded view of the second connecting member 2 according to an embodiment of the invention, respectively. FIGS. 8a, 8b illustrates a view of the second connecting member 2 and wiper blade adapter 41 according to an embodiment of the invention, respectively.

As shown in FIGS. 7a and 7b, the second connecting member 2 comprises a second body 21 and a first number of second contacts 22 which are electrically connected to each other and disposed at the second body 21. In this embodiment, the first number equals two. The second contacts 22 are made of an electrical conductive material, and the second body 21 is made of an insulated material. In this embodiment, two grooves 211 which open towards a same direction are provided on one side face of the second body 21, two second contacts 22 are disposed in these two grooves 211 respectively, and the grooves 211 receive the rod-shaped projections 111. Specifically, two cylindrical grooves 211 which open towards a same direction are provided on one side face surface of the second body 21, and are substantially complementary to the shapes of the two rod-shaped projections 111 of the first body 11, to allow the two grooves 211 to receive the two rod-shaped projections 111, respectively. Specifically, the second contact 22 is sheet-shaped, and includes a attaching portion 221 attached on the inner wall surface of the groove 211 and a press-contact portion 222 inclined to the central axis of the groove 211. The attaching portion 221 may be fixed on the inner wall surface of the groove 211 by pressing. Alternatively, the second contact 22 may also be in other shapes or be a coating, and may also be embedded in the inner wall of the groove 211 as long as at least one outer surface of the second contact 22 is exposed outwards. Two second contacts 22 may be integrally formed. Alternatively, the groove 211 is not limited to a hole shape and may be an open groove; the groove 211 is not limited to a cylindrical shape, and may be other shapes such as a cuboid.

As shown in FIGS. 7a and 7b, the second connecting member 2 may further include a sealing gasket mating groove 212 that is recessed inward from a side face which the opening of the groove 211 is towards.

As shown in FIGS. 8a and 8b, the shape of the second body 21 is adapted to be fixed in the housing of the wiper blade adapter 41. A first snap-fit structure 213 is also disposed on one side face of the second body 21, and a second snap-fit structure 411 which is mated with the first snap-fit structure 213 is disposed on the wiper blade adapter 41. In addition, the second body 21 is also provided with on the outer surface thereof a first positioning structure 214, and the wiper blade adapter 41 is provided with on the inner surface thereof a second positioning structure 412 that is mated with the first positioning structure 214, to facilitate the positioning and fixing of the second connecting member 2 in the housing of the wiper blade adapter 41. The second connecting member 2 can be snap-fitted into the housing of the wiper blade adapter 41. When mounting the second connecting member 2 onto the wiper blade adapter 41, firstly the orientation of the second connecting member 2 is adjusted, and then the second connecting member 2 is pressed into the housing of the wiper blade adapter 41 in the direction of the arrow shown in FIG. 8a. In other embodiments, the second connecting member 2 may be fixed in the housing of the wiper blade adapter 41 in other manners.

In this embodiment, as the first connecting member 1 and the second connecting member 2 are snap-fitted in the housing of the wiper arm adapter 31 and the housing of the wiper blade adapter 41 respectively, the first connecting member 1 and the second connecting member 2 can be easily mounted and detached and can achieve appropriate fixing effects, which allows the first connecting member 1 and the second connecting member 2 to be selected by users as options and be replaced easily.

FIG. 9 illustrates the first connecting member 1 and the second connecting member 2 being connected together according to an embodiment of the invention. Referring to FIGS. 3 and 9, the first connecting member 1 is fixed in the housing of the wiper arm adapter 31, and the second connecting member 2 is fixed in the housing of the wiper blade adapter 41. When the wiper blade adapter 41 is properly mounted to wiper arm adapter 31, said first connecting member 1 is connected to said second connecting member 2. Specifically, the extending direction of the cylindrical rod-shaped projections 111 of the first body 11, the extending direction of the grooves 211 of the second body 21, the long axis direction of the wiper arm adapter 31, and the long axis direction of the wiper blade adapter 41 are same. In this embodiment, as shown in FIG. 3, the wiper blade adapter 41 is pushed into the wiper arm adapter 31 in the direction of the arrow shown in FIG. 3, while the first connecting member 1 is connected to the second connecting member 2, such that the two rod-shaped projections 111 are respectively inserted into the two grooves 211, resulting in that the two first contacts 12 located on the outer surfaces of the rod-shaped projections 111 are in contact with the two second contacts 22 located in the grooves 211 respectively. In this way, the first contacts 12 that are electrically insulated from each other establish electrical connection therebetween by means of the second contacts 22 that are electrically connected to each other. Advantageously, the press-contact portion 222 of the second contact 22 presses against the first contact 12, such that the first contact 12 and the second contact 22 can be in better contact, and the sealing gasket 13 is received into the sealing gasket mating grooves 212 and are subjected to a pressure perpendicular to the surface thereof, such that the space in which the first contacts 12 and the second contacts 22 are located is well sealed to prevent the entry of liquid and prevent electric leakage.

In this embodiment, the connection between the first connecting member 1 and the second connecting member 2 may be fixed by the snap-fit member on the wiper arm adapter 41 and wiper arm adapter 31. In addition, corresponding snap-fit members may be provided on the first connecting member 1 and the second connecting member 2, to fix the connection between the first connecting member 1 and the second connecting member 2. The snap-fit members can apply pressure to the sealing gasket 13 in a direction perpendicular to its surface.

The wiper arm 3 and the wiper blade 4 of the motor vehicle are connected by a wiper arm adapter 31, which is typically located at the end of the wiper arm 3, and a wiper blade adapter 41, which is located near the mid-portion of the wiper blade 4, such that the wiper arm 3 drives the wiper blade 4 to swing back and forth. The wiper blade adapter 41 of the motor vehicle and the wiper arm adapter 31 corresponding thereto may be of various types. Herein, the direct insertion connection is used as an example for illustration, but is not limited thereto.

In some cases where the first connecting member 1 is connected to the wiper arm 3 by other means, the first connecting member 1 may be coupled with the second connecting member 2, for example, the first connecting member 1 may be inserted into the second connecting member 2 from one side, after assembling the wiper blade 4 to the wiper arm 3, that is, after assembling the wiper blade adapter 41 to the wiper arm adapter 31. For the wiper arm 3 and the wiper blade 4 which are assembled in other forms, the first connecting member 1 and the second connecting member 2 may be connected to the wiper arm 3 and the wiper blade 4 respectively in various ways, for example, the first connecting member 1 or the second connecting member 2 respectively does not necessarily be fixed in the housing of the wiper arm adapter 31 or the housing of the wiper blade adapter 41, and the mounting way and mounting sequence thereof may also be modified, as long as when the wiper blade 4 is properly mounted to the wiper arm 3, the first connecting member 1 is connected with the second connecting member 2 (not necessarily simultaneously), such that each of the first contacts 12 is in contact with the corresponding second contact respectively, and thus the first contacts 12 are electrically connected to each other through the second contacts 22.

The alarming system for the wiper may further include a control member (not shown in the figures), which is configured to sense the electrical connection between the first contacts 12, and to generate an alarm signal when the electrical connection between the first contacts 12 is disconnected.

The control member may be located at the body of the vehicle, and specifically, the control member may be included in ECU of the vehicle. As shown in FIG. 2, the first connecting member 1 is connected to the corresponding inputs of the ECU by signal lines 5. Since the wiper arm 3 is moved at the time of operation, at least a part of the signal line 5 extends along the wiper arm 3 and is fixed to the wiper arm 3, in order to prevent the signal line 5 from being wound or damaged.

FIG. 10 illustrates a view of the wiper arm 3 and the signal line retaining clip 6 according to an embodiment of the invention. FIG. 11 illustrates a perspective view of the signal line retaining clip 6 according to an embodiment of the invention. As shown in FIG. 10, the signal line 5 can be fixed to the wiper arm 3 by the signal line retaining clip 6. As shown in FIG. 11, the signal line retaining clip 6 is substantially an annular structure having an opening 61, and the signal line retaining clip 6 further includes a recess 62 that protrudes outward. As shown in FIG. 10, the signal line retaining clip 6 has elasticity, its opening can be temporarily expanded. The signal line retaining clip 6 can be nested on the wiper arm 3 from the direction shown in FIG. 10, and the signal line 5 is fixed in the recess 62. Alternatively, the signal line 5 may also be located in the interior cavity of the wiper arm 3.

As described above, when the wiper blade 4 is properly mounted to the wiper arm 3, the first connecting member 1 and the second connecting member 2 are connected so that each of the first contacts 12 is respectively in contact with the corresponding second contact, thereby the two first contacts that are insulated from each other establish electrical connection therebetween by two second contacts 22 that are electrically connected to each other.

When the wiper blade 4 is detached from the wiper arm 3, for example when it is stolen, since the first connecting member 1 is connected to the wiper arm 3 and the second connecting member 2 is connected to the wiper blade 4 (specifically, for example, the first connecting member 1 is fixed in the housing of the wiper arm adapter 31, and the second connecting member 2 is fixed in the housing of the wiper blade adapter 41), the first connecting member 1 is not removed together with the wiper blade 4, while the second connecting member 2 is removed together with the wiper blade 4. In this way, the first connecting member 1 is no longer connected with the second connecting member 2, thereby causing the electrical connection between the two first contacts 12 through the second contact 22 to be disconnected. After the control member senses that the electrical connection between the two first contacts 12 is disconnected, an alarm signal is generated. Here, the control member includes the ECU, the ECU generates an alarm signal, and may control the alarm of the vehicle to generate a sound, and may also control the camera on the motor vehicle to capture the image around the motor vehicle.

The control member may also be configured to send alarm information to alarm information receiver. The alarm information receiver may be a mobile terminal, for example, a user's smart phone, tablet computer, laptop computer and the like. The alarm information receiver can also be a computer, a server, etc., and the server can further push related alarm information to the user. In this way, the user can instantly know the abnormal condition of the wiper blade 4 on the wiper. After the mobile terminal receives the alarm information, it can receive the image(s) captured by the camera to view the situation around the motor vehicle, or can turn off the alarm, and so on.

The alarming system can also monitor whether the wiper blade 4 is properly mounted on the wiper arm 3. For example, in the embodiment shown in FIG. 3, if the wiper blade 4 is not properly mounted on the wiper arm 3, the first contact 12 and the second contact 22 can not contact well, resulting in a disconnection of the electrical connection between the first contacts 12, and further causing the control member to generate an alarm signal.

FIG. 12 illustrates an exploded view of the first connecting member 1 according to another embodiment of the invention. As shown in FIG. 12, the alarming system further comprises a wireless transmitting member positioned in the first body 11 and a wireless receiving member coupled to the control member. The wireless receiving member may be included in the control member. The control member may be configured to sense the electrical connection between the first contacts 12 via the wireless transmitting member and the wireless receiving member. The first contacts 12 may be electrically connected to respective inputs of the wireless transmitting member, and the wireless transmitting member and the wireless receiving member may communicate via protocols such as Bluetooth, ZigBee, NFC, and the like. Specifically, the wireless transmitting member sends a signal to the wireless receiving member when the electrical connection between the first contacts 12 is disconnected. The wireless receiving member then sends a signal to the control member if the wireless receiving member is a member independent of the control member, and in this way, the control member senses the disconnection of the electrical connection between the first contacts 12, thereby generating an alarm signal. If the wireless receiving member is included in the control member, the control member directly receives the transmitted signal sent from the wireless transmitting member, and in this way, the control member senses the disconnection of the electrical connection between the first contacts 12, thereby generating an alarm signal.

The wireless transmitting member may include a battery 71 for supplying power. As shown in FIG. 12, the battery 71 is a button battery, and a battery space 72 for accommodating the battery 71 is provided in the first body 11. In addition, a seal ring 73 and a battery cap 74 for enclosing the battery space 72 are provided above the battery 71. The battery cap 74 is provided with a radial projection 741 on an outer periphery thereof, and the battery space 72 is provided with a radial groove 721 mated with the radial projection 741 and a mounting opening 722 that has a shape mated with the shape of the radial projection 741. A battery cap 74 is placed in the mounting opening 722, the battery cap 74 is rotated, such that the battery cap 74 is snap-fitted into the radial groove 721, and a vertical direction force is applied to the seal ring 73 to seal the battery space 72. The wireless transmitting component and the wireless receiving component may be, for example, a Bluetooth transmitting member and a Bluetooth receiving member.

In other embodiments, if the first connecting member 1 does not need to be connected to the control member on the vehicle body in a wired manner, for example, if the control member senses the connection between the first contact 12 through the wireless transmission member and the wireless receiving member, the first connecting member 1 may also be connected to the wiper blade 4, and the second connecting member 2 may be connected to the wiper arm 3.

In other embodiments, the first connecting member 1 and the second connecting member 2 may be in other configurations.

For example, in an embodiment, the first body 11 is provided with a first number of grooves that open in a same direction, and the first contacts 12 are disposed in the first number of grooves respectively.
