Description

Technical Field

[0001] The invention relates to the technical field of motorcycle brake oil pumps, and more specifically to a motorcycle brake oil pump assembly. Background Art

[0002] A motorcycle brake pump, as the name implies, is a component used to brake a motorcycle. A Chinese patent discloses a motorcycle brake pump that is easy to repair with patent number CN202323228753.1. The utility model adopts a structural design that can position the retaining spring. During the user's disassembly and repair process, the retaining spring will not be randomly ejected without a regular pattern, so that the user can easily put away the parts to avoid loss. Moreover, with the assistance of the latch and the positioning ring, the retaining spring can be easily and quickly installed in the appropriate position without repeated adjustment, which saves time for the user's disassembly and assembly work, and improves the user's efficiency in repairing the motorcycle brake pump, providing convenience for the user's repair work. However, there is still a problem. The problem is that the motorcycle brake lower pump is installed and positioned between the brake pad and the pump housing by a pin cooperating with the socket, and the brake pad is pressed against the brake pad by a retaining spring. Since the outer diameter of the pin is matched with the sockets on the brake pad and the pump housing, and the gap between the pin and the socket is small, the pin needs to overcome the elastic force given by the retaining spring when passing through the sockets on the pump housing and the brake pad. The elastic force given by the retaining spring will cause the socket on the brake pad and the socket on the pump housing to be not completely in a straight line, but staggered, which will affect the insertion of the pin. Since some existing pins are relatively simple, most of them are an integrated rod-shaped structure, it is actually more troublesome to insert the pin, which reduces the convenience of use. Summary of the invention

[0003] The object of the present invention is to provide a motorcycle brake oil pump assembly to solve the problems raised in the above background technology:

[0004] Some existing motorcycle brake pumps are installed and positioned between the brake pad and the pump housing by means of a pin and a socket, and the brake pad is pressed against a retaining spring. Since the outer diameter of the pin is matched with the sockets on the brake pad and the pump housing, and the gap between the pin and the socket is small, the pin needs to overcome the elastic force given by the retaining spring when passing through the sockets on the pump housing and the brake pad. The elastic force given by the retaining spring will cause the socket on the brake pad and the socket on the pump housing to be not completely in a straight line, but staggered, which will affect the insertion of the pin. Since the pins are relatively simple and most of them are an integrated rod-shaped structure, it is actually quite troublesome to insert the pin, which reduces the convenience of use.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A motorcycle brake oil pump assembly comprises a pump housing and a latch assembly, wherein the latch assembly comprises a latch rod, one end of the latch rod is fixedly connected to a threaded rod, the other end of the latch rod is fixedly connected to a bolt head, a slot is provided on a side of the bolt head away from the latch rod, and the slot is convenient for a user to screw the bolt head with different tools, a first groove is provided on the inner side of the latch rod close to the bolt head, a first support rod is arranged inside the first groove, the first support rod is rotatably connected to the latch rod, an end of the first support rod that is rotatably connected to a support plate is provided on the outer side of the latch rod away from the latch rod, and the outer side of the latch rod and the position between the support plate and the bolt head A blocking piece is sleeved therein, and the blocking piece is slidably connected to the latch rod, and a connecting rod is rotatably connected between the blocking piece and the first support rod, a second groove is provided on the side of the latch rod away from the bolt head, four of the first groove and the second groove are provided, and are symmetrically distributed on the four side positions of the latch rod, a second support rod is provided inside the second groove, one end of the second support rod is rotatably connected to the latch rod, and the other end of the second support rod is rotatably connected to the support plate, a threaded hole is provided inside the pump housing, the threaded hole is used in conjunction with the threaded rod, and after the threaded rod and the threaded hole are combined, the stability of the entire latch assembly on the pump housing can be ensured.

[0007] Preferably, a third groove is provided inside the bolt head on one side close to the latch rod, a sliding rod is slidably connected inside the third groove, the sliding rod is fixedly connected to the blocking piece, a first spring is provided between the sliding rod and the third groove, the elastic force of the first spring drives the blocking piece to reset via the sliding rod in the third groove, and during the resetting of the blocking piece, the blocking piece will drive the first support rod to rotate toward the direction close to the latch rod via the connecting rod, and cooperate with the second support rod to fold the support plate, so that the overall diameter of the latch assembly becomes smaller, which is beneficial for the installation and disassembly of the latch assembly.

[0008] Preferably, a fourth groove is provided inside the latch rod, the fourth groove is arranged at one side position of the first groove and the second groove, and is symmetrically distributed at two opposite side positions on the latch rod, the fourth groove is slidably connected to a slider inside, a second spring is provided between the slider and the fourth groove, a sleeve is provided on the outside of the latch rod, the sleeve is slidably connected to the latch rod, and the slider is fixedly connected to the sleeve, when the first support rod and the second support rod leave the first groove and the second groove, the first groove and the second groove are directly connected to the outside, if small stones or other debris enter the first groove or the second groove, it will affect the entry of the first support rod and the second support rod, so that the support plate cannot be folded normally, so the first groove and the second groove are blocked by the sleeve.

[0009] Preferably, a fifth groove is provided on the inner side of the sleeve away from the slider, and the first support rod and the second support rod are both used in conjunction with the fifth groove, and the first support rod and the second support rod are both located on the inner side of the fifth groove. When the first support rod or the second support rod rotates toward the direction close to the latch rod, the first support rod or the second support rod will squeeze the inner wall of the fifth groove, thereby pushing the sleeve away from the first groove or the second groove, so that the first support rod can enter the first groove and the second support rod can also enter the second groove, thereby realizing folding of the support plate.

[0010] Preferably, a pin hole is provided on the inner side of the threaded rod away from the latch rod, a bayonet is inserted into the inner side of the pin hole, a sixth groove is provided on the inner side of the threaded rod away from the latch rod at one end, the sixth groove is used in conjunction with the bayonet, and after the brake pad and the pump housing are installed and positioned by the latch assembly, the user can insert the bayonet into the pin hole on the threaded rod, limit the latch assembly by the bayonet, and after the bayonet pin is inserted into the pin hole, the bayonet pin is twisted so that the bayonet pin engages with the sixth groove at one end of the threaded rod, thereby limiting the bayonet pin itself.

[0011] Preferably, the cross-section of the support plate is an arc-shaped structure. There are four support plates in total, and the four support plates are symmetrically distributed on the four side positions of the latch rod. Since the cross-section of the support plate is an arc-shaped structure, when the four support plates are unfolded, an approximately cylindrical latch can be formed, and the outer diameter of the latch is compatible with the inner diameter of the socket on the pump housing and the brake pad. After the latch passes through the socket, the brake pad can be installed and positioned on the pump housing.

[0012] Preferably, the outer wall of the latch rod fits with the inner wall of the sleeve, and the cross-sections of the latch rod and the sleeve are both square structures. The sleeve can slide back and forth on the latch rod. Since the latch rod and the sleeve fit tightly, the sleeve will not shake when sliding back and forth on the latch rod.

[0013] Preferably, the first support rod and the second support rod have the same size. Since the first support rod and the second support rod have the same size, a parallelogram is formed between the support plate, the first support rod, the second support rod and the latch rod, so that the support plate and the latch rod always remain parallel, ensuring that the outer wall of the support plate fits with the pump housing and the inner wall of the socket on the brake pad.

[0014] Preferably, the first support rod is an H-shaped structure. The H-shaped first support rod has an opening at the bottom of the first support rod. The space formed by the opening can accommodate the connecting rod on the first support rod, so that when the connecting rod drives the first support rod to rotate, there will be no interference or jamming between the connecting rod and the first support rod, thereby ensuring that the first support rod and the connecting rod can both enter the first groove, thereby folding the support plate to the maximum extent.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1) When the motorcycle brake oil pump assembly is in use, generally the overall diameter of the latch assembly is smaller than the diameter of the insertion hole. Therefore, even if the insertion hole on the brake pad and the insertion hole on the pump housing are staggered, it will not be affected, and the user does not need to deliberately press the retaining spring, which makes the installation of the latch assembly more convenient. After the latch assembly is installed in place, it is forwardly screwed through the bolt head so that the threaded rod is combined with the threaded hole on the pump housing. When the baffle plate is tightly pressed against the pump housing, the baffle plate will move relative to the bolt head in a direction close to the bolt head. At this time, the baffle plate drives the first support rod to rotate in a direction away from the latch rod through the connecting rod, and cooperates with the second support rod to drive the support plate to automatically expand until the outer wall of the support plate fits and presses against the inner wall of the insertion hole, and finally completes the installation. Since the overall diameter of the latch assembly is smaller before being inserted into the insertion hole, it is easier and more convenient for the latch assembly to be inserted and pass through the insertion hole, thereby improving the convenience of use.

[0017] 2) When the motorcycle brake oil pump assembly is in use, when the user screws the bolt head in the forward direction, the first support rod will rotate out of the first groove, and the second support rod will also rotate out of the second groove. At this time, the elastic force of the second spring will drive the sleeve on the latch rod to slide toward the first groove and the second groove through the slider, thereby blocking the first groove and the second groove through the sleeve to prevent pebbles or other debris from entering the first groove or the second groove.

[0029] Embodiment 1

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 10A motorcycle brake oil pump assembly includes a pump housing 1 and a latch assembly 2, wherein the latch assembly 2 includes a latch rod 201, one end of the latch rod 201 is fixedly connected to a threaded rod 202, the other end of the latch rod 201 is fixedly connected to a bolt head 203, a slot is provided on the bolt head 203 on a side away from the latch rod 201, and the slot is convenient for the user to screw the bolt head 203 with different tools, a first groove 204 is provided on the inner side of the latch rod 201 close to the bolt head 203, a first support rod 205 is provided inside the first groove 204, the first support rod 205 is rotatably connected to the latch rod 201, an end of the first support rod 205 away from the latch rod 201 is rotatably connected to a support plate 206, and a baffle is sleeved on the outer side of the latch rod 201 and located between the support plate 206 and the bolt head 203 207, the baffle 207 is slidably connected to the latch rod 201, and a connecting rod 208 is rotatably connected between the baffle 207 and the first support rod 205. A second groove 209 is provided on the side of the inside of the latch rod 201 away from the bolt head 203, and four first grooves 204 and second grooves 209 are provided, and are symmetrically distributed on the four side positions of the latch rod 201. A second support rod 210 is provided inside the second groove 209, and one end of the second support rod 210 is rotatably connected to the latch rod 201, and the other end of the second support rod 210 is rotatably connected to the support plate 206. A threaded hole 219 is provided inside the pump housing 1, and the threaded hole 219 is used in conjunction with the threaded rod 202. After the threaded rod 202 is combined with the threaded hole 219, the stability of the entire latch assembly 2 on the pump housing 1 can be ensured, and it is not easy to get loose.

[0032] Furthermore, a third groove 211 is provided inside the bolt head 203 on one side close to the latch rod 201, and a slide rod 212 is slidably connected inside the third groove 211. The slide rod 212 is fixedly connected to the baffle 207, and a first spring 213 is provided between the slide rod 212 and the third groove 211. The elastic force of the first spring 213 drives the baffle 207 to reset via the slide rod 212 in the third groove 211. During the resetting process of the baffle 207, the baffle 207 will drive the first support rod 205 to rotate toward the direction close to the latch rod 201 via the connecting rod 208, and cooperate with the second support rod 210 to fold the support plate 206.

[0033] Furthermore, a pin hole 3 is provided on the inner side of the threaded rod 202 away from the latch rod 201, and a bayonet pin 4 is inserted into the inner side of the pin hole 3. A sixth groove 5 is provided on the inner side of the threaded rod 202 away from the latch rod 201, and the sixth groove 5 is used in conjunction with the bayonet pin 4. After the brake pad and the pump housing 1 are installed and positioned by the latch assembly 2, the user can insert the bayonet pin 4 into the pin hole 3 on the threaded rod 202, and limit the latch assembly 2 by the bayonet pin 4. After the bayonet pin 4 is inserted into the pin hole 3, the bayonet pin 4 is twisted so that the bayonet pin 4 engages with the sixth groove 5 at one end of the threaded rod 202, thereby limiting the bayonet pin 4 itself, so that the bayonet pin 4 will not shake or swing in the pin hole 3.

[0034] Furthermore, the cross-section of the support plate 206 is an arc-shaped structure. There are four support plates 206 in total, and the four support plates 206 are symmetrically distributed on the four side positions of the latch rod 201. Since the cross-section of the support plate 206 is an arc-shaped structure, when the four support plates 206 are unfolded, a nearly cylindrical latch can be formed, and the outer diameter of the latch is compatible with the inner diameter of the socket on the pump housing 1 and the brake pad.

[0035] Furthermore, the first support rod 205 and the second support rod 210 have the same size. Since the first support rod 205 and the second support rod 210 have the same size, a parallelogram is formed between the support plate 206, the first support rod 205, the second support rod 210 and the latch rod 201, so that the support plate 206 and the latch rod 201 always remain parallel.

[0036] Furthermore, the first support rod 205 is an H-shaped structure. The H-shaped first support rod 205 makes the bottom of the first support rod 205 have an opening. The space formed by the opening can accommodate the connecting rod 208 on the first support rod 205, so that when the connecting rod 208 drives the first support rod 205 to rotate, there will be no friction or jamming between the connecting rod 208 and the first support rod 205, thereby ensuring that the first support rod 205 and the connecting rod 208 can both enter the first groove 204, and then the support plate 206 is folded to the maximum extent, reducing the overall diameter of the latch assembly 2.

[0037] The use steps of the present invention are as follows: when the motorcycle brake oil pump assembly is in use, generally, due to the elastic force of the first spring 213, the slide bar 212 in the third groove 211 will move toward the direction close to the latch rod 201, so that the slide bar 212 drives the baffle 207 away from the bolt head 203, and the baffle 207 drives the first support rod 205 on one side of the support plate 206 to rotate toward the direction close to the latch rod 201 through the connecting rod 208, so that the first support rod 205 rotates to the inside of the first groove 204. During the process, the second support rod 210 on the other side of the support plate 206 rotates to the inside of the second groove 209, and finally the support plate 206 is folded. At this time, the overall diameter of the latch assembly 2 is very small. After the user puts the brake pad and the retaining ring into the pump housing 1, the latch assembly 2 is inserted from one side of the pump housing 1 and passes through the insertion holes on the pump housing 1 and the brake pad in turn. Since the overall diameter of the latch assembly 2 is smaller than the diameter of the insertion hole at this time, even if the insertion hole on the brake pad and the insertion hole on the pump housing 1 are staggered at this time, it will not be affected. The user does not need to deliberately press the retaining spring, which makes the installation of the latch assembly 2 more convenient. After the latch assembly 2 is installed in place, the bolt head 203 is screwed forward to make the threaded rod 202 engage with the threaded hole 219 on the pump housing 1. During the process of screwing the bolt head 203 forward, the bolt head 203 and the baffle 207 will move toward the pump housing 1. When the baffle 207 is pressed against the pump housing 1, as the user continues to screw the bolt head 203, the baffle 207 will move relative to the bolt head. 203 moves in the direction close to the bolt head 203, at this time, the blocking piece 207 will drive the first support rod 205 to rotate in the direction away from the latch rod 201 through the connecting rod 208, and cooperate with the second support rod 210 to drive the support plate 206 to automatically unfold until the outer wall of the support plate 206 fits tightly against the inner wall of the socket, and finally the installation is completed. Since the overall diameter of the latch assembly 2 is smaller before being inserted into the socket, it is easier and more convenient for the latch assembly 2 to be inserted and pass through the socket, thereby improving the convenience of use.

[0038] Embodiment 2

[0039] When the support plate 206 is unfolded, the first support rod 205 is not inside the first groove 204, and the second support rod 210 is not inside the second groove 209. At this time, the first groove 204 and the second groove 209 are directly connected to the outside world. Due to the working environment of the motorcycle brake oil pump, in order to prevent small stones and other debris from falling into the first groove 204 or the second groove 209 and avoid affecting the folding of the support plate 206, the following solution is used to solve this problem.

[0040] See also Figures 1 to 10, the basis for the combined implementation is different in that a fourth groove 214 is provided inside the latch rod 201, the fourth groove 214 is arranged at one side of the first groove 204 and the second groove 209, and is symmetrically distributed at two opposite side positions on the latch rod 201, a slider 215 is slidably connected inside the fourth groove 214, a second spring 216 is arranged between the slider 215 and the fourth groove 214, a sleeve 217 is sleeved outside the latch rod 201, the sleeve 217 is slidably connected to the latch rod 201, the slider 215 is fixedly connected to the sleeve 217, when the first support rod 205 and the second support rod 210 leave the first groove 204 and the fourth groove 209, When the first groove 204 and the second groove 209 are formed, the first groove 204 and the second groove 209 are directly connected to the outside. If small stones or other debris enter the first groove 204 or the second groove 209, it will affect the entry of the first support rod 205 and the second support rod 210, making it impossible for the support plate 206 to fold normally. Therefore, the first groove 204 and the second groove 209 are blocked by the sleeve 217. When the first support rod 205 and the second support rod 210 are rotated out of the first groove 204 and the second groove 209, the elastic force of the second spring 216 will drive the sleeve 217 to block the outside of the first groove 204 and the second groove 209 through the slider 215.

[0041] Furthermore, a fifth groove 218 is provided on the inner side of the sleeve 217 away from the slider 215, and the first support rod 205 and the second support rod 210 are both used in conjunction with the fifth groove 218. The first support rod 205 and the second support rod 210 are both located on the inner side of the fifth groove 218. When the first support rod 205 or the second support rod 210 rotates toward the direction close to the latch rod 201, the first support rod 205 or the second support rod 210 will squeeze the inner wall of the fifth groove 218, thereby pushing the sleeve 217 away from the first groove 204 or the second groove 209, so that the first support rod 205 can enter the first groove 204, and the second support rod 210 can also enter the second groove 209.

[0042] Furthermore, the outer wall of the latch rod 201 fits with the inner wall of the sleeve 217, and the cross-sections of the latch rod 201 and the sleeve 217 are both square structures. The sleeve 217 can slide back and forth on the latch rod 201. Since the latch rod 201 fits tightly with the sleeve 217, the sleeve 217 will not shake when sliding back and forth on the latch rod 201, thereby improving the stability of the sleeve 217 when sliding back and forth on the latch rod 201.

[0043] The steps of using the present invention are as follows: when the motorcycle brake oil pump assembly is in use, when the user screws the bolt head 203 in the forward direction, the first support rod 205 will rotate out of the first groove 204, and the second support rod 210 will also rotate out of the second groove 209. At this time, the elastic force of the second spring 216 will drive the sleeve 217 on the latch rod 201 to slide in the direction close to the first groove 204 and the second groove 209 through the slider 215, so that the first groove 204 and the second groove 209 are blocked by the sleeve 217 to prevent pebbles or other debris from entering the first groove 204 or the second groove 209. When the latch assembly 2 is removed, the first support rod 205 and the second support rod 210 will squeeze the inner wall of the fifth groove 218 on the sleeve 217, thereby pushing the sleeve 217 away until the first support rod 205 and the second support rod 210 enter the first groove 204 and the second groove 209 respectively.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
